高中生科普类英语文章阅读题目
高中英语阅读理解题型
阅读理解是英语考试中的一个重点和难点。下面由我为大家带来了高中英语阅读理解题型解读和解题技巧，一起来看看吧!
【高中阅读理解题型解读】
(一)阅读是获得更综合、更复杂、更精确信息的必要手段，考生在做阅读理解时，不仅要看懂文章的字面意思，还需要针对不同题材和体裁的篇目运用不同的方法作出正确的选择。一般来说，词汇、阅读速度和理解能力是阅读理解中三个最重要且有相互联系的因素。
阅读的方法可以使用以下几种：
1.跳读：就是快速的一步阅读法。实际上是有选择阅读，找关键词。用这种阅读方法回答who、what、when、where之类的问题最为有效。
2.略读：指比跳读慢些的二步阅读法。即泛泛地、粗略地快速阅读，目的是了解大意，对文章有个总的概念。此种阅读方法能回答why、how之类的问题。
3.精读：即最细致、最慢的深层阅读方法，目的是求得对所读文章的全部意义的理解与掌握。
在使用阅读技巧时尽量做到以下几点：
1.带着问题阅读短文。
2.找出主题句、确定中心思想。
3.推断单词、句子和文章的含义。
4.尽快选择答案。
(二)不同体裁文章的特点及解题技巧
1.记叙文
记叙文又可分传记类和故事类。 传记类文章在阅读中时间是全文的关键，根据时间我们可以找到相关的事件，抓住文章的主要内容。故事类文章情节性较强，阅读时要注意故事中的时间、地点、人物和发生的事件，这些都是文章中的主要内容和信息，对于准确理解文章十分重要。
2.说明文
说明文是对事物的形状、性质、特征、成果或功用等进行介绍，解释或阐述的文章。把握所说明事物的特征和本质是理解说明文的关键。说明事物特征的方法很多，主要有定义法、解释法、比较法、比喻法、数字法、图表法、引用法和举例法等。
数字说明文
在阅读数字说明文时要特别注意文中数字的含义，从这些数字中可以找到文章的主要内容。
解释说明文
解释说明文着重说明事物的本质、特征和功用等。许多科普文章都属于这一类。在阅读这类文章时要学会解决what, how, why 等一类的问题。它们是文章的关键。如能带着这些问题阅读，将会更迅速抓住文章的主题。
比较说明文 比较说明文是通过对比方法说明问题。在阅读这类文章时要善于把握全篇陈述的基本倾向。作者在谈论一个有争议的问题时总要顾及到争议的各个方面。但是，在一般情况下，作者的陈述总要倾向于某一种观点。
3.应用文
应用文涉及的.范围比较广，包括广告、通知、书信等。应用文一般语言简洁，省略及不规范的句子较多。阅读时一般要求考生全面掌握文章中提供的信息，并运用这些信息去解决问题。因此对题干的理解尤为重要。
阅读理解的考题分为客观理解题(是指在短文中客观存在的事实，客观信息的答案一般都可以在原文中找到。即理解文中的具体事实或抽象概念)和主观理解题(这类问题都不可能直接从原文中找到答案，须通过阅读文章对文章主旨和深层含义有更深理解，并据此进行判断和推理)。其中细节理解题和猜测词义题属于客观题;主旨大意题和推理判断题属于主观题。针对不同类型的题目，要在平时的练习过程中，结合具体的题目，给学生进行解题方法的指导和讲解。对于客观题，要提醒他们阅读时关注文章的细节，如时间，地点或一些具体数字，在选择答案时，务必从原文中找到确切的依据。 我们可将阅读理解归纳为以下四大题型，根据阅读理解题考查角度的不同，可采用不同的解题技巧来应付。
Ⅰ.事实细节题
属于细节类型的阅读理解题一般只针对某个特定的细节，题型可以多种多样。此类题型一般分两种。第一种是直接理解题，在原文中可以直接找到答案。第二种是词义转换题，正确选项是原文有关词语和句子的转换。做此类试题一定要抓住事件发生的时间、地点、人物、发展过程和结局等环节，所选答案一定要符合原文，切不可望文生义。这类题型的主要提问方式常为：
①Which of the following is true/NOT true in the passage?
②Which of the following statements is NOT discussed/mentioned in the passage?
③Which is the right order of the events given in the passage?
④All the following statements are NOT true excep. 细节题的破解一般采用寻读法，即先看试题，再读文章。对有关信息进行快速定位，再将相关信息进行整合、甄别、分析、对比，有根有据地排除干扰项，选出正确答案。此法加强了阅读的针对性，提高了做题的准确率，节省了宝贵的时间。寻读法还特别适用于对图形表格类题材的理解。做此类型的题目还要特别注意句子的逻辑关系。英语中有许多功能词，如：表因果关系的because, since, as等;表转折关系的but, however ,on the contrary, on the other hand等等。
Ⅱ.猜测词义题
在高考阅读题中，考生遇到的最大障碍往往有两个：一是被已认识的单词的某一熟知含义所误导;二是被完全不认识的单词的意思所阻碍，从而出现理解偏差或理解困难，影响阅读的速度。其实解决这两个困难的一个重要法宝是考生在心目中树立起上下文观念，要学会“顺藤摸瓜”，通过构词，语法，定义，同位，对比，因果，常识，上下文等线索确定词义。
在阅读解题时要注意从以下七个方面着手：
1)根据定义或解释、说明猜测生词的词义 在be,be called,call等判断词出现的判断句中，或定语从句及标点符号，可以根据已知部分，猜测生词的含义。例如：
The herdsman, who looks after sheep, earns about 650 yuan a year.通过理解定语从句的意思，能猜出herdsman是“牧人”。
2)根据对比关系猜测生词的词义 在but,however,yet,otherwise,though这些表示意义转折的连词出现的句子中，其前后的词有明显对比关系，根据已知的内容，通过这种对比关系，就很容易猜出生词的词义了。例如： Though Tom’s face has been washed quite clean, his neck still remains grubby. 和clean意思相对的便是“肮脏的”了，因此可猜出句中grubby的意思是“肮脏的”。
3)通过因果关系猜测词义 because, since与as是连接原因状语从句的从属连词，so是连接表示结果的状语从句的连词，so……that与such……that中的that是连接结果状语从句的。当这些信息词出现在有生词的句子中，通过因果关系，依据已知部分就能猜出生词的词义。例如：She wanted the hairdresser to trim her hair a bit because it was too long. 根据because从句所讲的意思，我们就可推测trim就是“修剪”之意。
4)根据生活常识猜测词义
3 运用逻辑推理能力，自身的生活经验及生活常识。再联系上下文能读懂的部分，可以正确猜出词义。例如：Most of the roses are beginning to wither because of the cold. 根据句子意思及生活经验，wither表示“枯萎”。
5)根据同等关系猜测词义 同等关系，指的是一个词，一组词或短语在句中作同一成分，而且它们的词义都属于同一范畴。明显的标志是，这样的词组或短语中间常常用并列连词and或or来连接。例如： At forty-two he was in his prime and always full of energy. 从“年龄42岁”以及与prime具有同等关系的full of energy可以猜出prime的意思是“盛年时期”。
6)根据列举的事例猜测词义 You can take any of the periodicals: "The World of English". "Foreign Language Teaching in Schools", or "English Learning". 从后面列举的例子中，可以猜出periodical是“期刊，杂志”的意思。
7)根据构词法知识猜测词义 根据学过的构词法知识，知道词根和前缀或后缀的意义，就可猜出由它们组成的新词词义。
Ⅲ.推理判断题
做这类题要求考生在阅读理解整体语篇的同时，又要求学生对作者的态度、意图及文章细节的发展作正确的推理判断，力求从作者的角度去考虑，不要固守自己的看法或观点。不要主观臆断，凭空想象，任意发挥，而走入误区。学生要学会运用主题句去推测、揣摩文字背后作者的意图，运用归纳、对比、演绎技能，运用背景知识去挖掘文章深层含义，从而正确理解作者的言外之意，同时认真体会文章的语气与感情基调(如：否定、厌恶、反问、讽刺等)。
这类试题常以如下句式发问：
①What can you conclude/ imply from this passage?
②What’s the author’s attitude(态度)towards……?
③We can infer /learn from the passage that……
如： Once there was something wrong with a machine in a factory. The workers could do nothing but turn to a German engineer for help, who drew a line on it and said, “Take off the part where the line is and change it for a new one. ”The machine, with a new line on, began running well again. The engineer then asked for $ 30,000 for what he had done. The following were what he wrote on a bill, “The new part only costs one dollar, and knowing where the problem with the machine is costs $ 29,999.”
Q: What can you conclude from this passage?
A. the engineer asked for too much money
B. the workers should pay the money
C. the knowledge is worth money
D. the new part could cost more
这篇短文是作者讲的一个故事，那么通过这个故事我们可以判断出什么呢?虽然作者没有言明，但是我们可以断定，发现问题的所在需要智慧和知识，知识是创造价值的源泉，因此此题的正确答案应为C. Ⅳ.主旨大意题 这种题型要求考生能够把握文章的总体，并真正理解主题和中心;要求能较好地运用概括、判断、归纳、推理等逻辑思维方法解题，难度较大，属于高层次题。

听点小音乐 轻松学分数
Stuck on a tricky math problem? Start clapping. Grade school kids who learned about fractions through a rhythm-and-music-based curriculum outperformed their peers in traditional math classes. The work is inEcational Studies in Mathematics.
被一条数学题难住了?拍拍手试试吧。研究表明，小学生在有节奏感的音乐背景下学习分数知识的效果会好于传统课堂(具体研究发表在《数学教育研究》上的《学术性音乐：如何用音乐辅助三年级小学生学习基础分数》一文，作者：苏珊·科瑞等)。
Fractions let you divide up a measure of music into notes of varying length. For example, one four-beat measure could contain a single whole note held for all four beats, two half notes of two beats apiece, four quarter notes of a beat each, and so on. In the Academic Music program, based on the Kodaly method of musical ecation, students clap, drum and chant to memorize the lengths of musical notes—then solve problems in which fractional notes must add up to a full measure of music.
根据分数的概念，一节音乐可分成长短不一的几串音符。例如，一节四拍子的调子可包含一个代表四拍子的全音符，两个各代表一个二拍子的二分音符，四个各代表一个一拍子的四分音符……以此类推。在“学术性音乐”项目中，研究人员以科达伊的音乐教育 方法 为基础，让学生通过打拍子、敲鼓、合唱记住各音符的长度，学生必须把这些片段加起来，才能得到一节完整的音乐——如此实践可解决学生对分数的疑惑。
Sixty-seven students participated in the study. Half did math problems using the Academic Music system. And after six weeks, the students in the music program averaged 50 percent higher on tests than did the kids in regular math class. Fractions create a solid foundation for further math ecation—so mastering them is music to ecators' ears.
有67名学生作为实验对象参与了本次研究，其中有一半在“学术性音乐”体系下解决数学问题。六周后，他们在测试中的得分要比普通班级中的学生平均高50%。分数是进一步进行数学知识教学的基础——如此看来，这还多亏了教育者的耳朵。

十万年前的颜料工作室
Archeologists have discovered a paint proction studio in an ancient South African cave A new archaeological find may signify one of the great leaps in human cultural and cognitive history. Because researchers have discovered a 100,000-year-old art studio. It was known that ochre—rock with red or yellow pigments—was used for paint even that far back in history. But there was scant evidence for how it was prepared and handled. Then, in 2008, researchers uncovered an ochre mixing kit in a South African cave. They found two abalone shells, most likely used for paint mixing and storage. They also found ochre, bone, charcoal, grindstones and hammerstones. The researchers say the ochre was probably rubbed on quartzite slabs to create a fine powder. It was then mixed and heated with other crushed substances, including other stones or mammal-bone. Microscopic striations on the inner abalone surface likely are likely scrape marks left ring paint mixing. The research was published in the journal Science. The paint may have been used for body adornment or for long-gone artwork. And the presence of this paint-proction laboratory indicates that the early humans knew basic chemistry and could plan for the future.
考古学家在南非的一个古老洞穴中发现了一个油漆制作工作室。这个新的考古发现可能是人类 文化 和认知历史的最伟大的跨越之一。因为研究人员发现的这个工作室产生于十万年前。众所周知，拥有红色或黄色色素的赭石岩一直被广泛运用于绘画中，但却少有证据显示它是如何制作并运用的。2008年，研究人员 在南非的山洞中发现了赭石混合工具， 两个可能用于调漆和储存的鲍鱼壳，除此之外他们还发现了赭石，骨头，炭笔和石锤。研究人员称，这些赭石很有可能经过在石英岩板上仔细研磨后，得到上等的粉末，然后再与 其他石头或者是哺乳动物的粉末混合并加热。用显微镜观察鲍鱼壳的内表面，你可以发现一些刮痕，这些都有可能是在混合颜料的过程中留下来的。这个发现已经被刊登在科学期刊上。这些颜料可能一直被运用在人体 彩绘 和长久失传的艺术品上。而且这些颜料制作工作室的存在表明了早期人类对化学已有了基本的了解并具有了规划未来的能力。颜料工具的一小步，人类历史的一大步——辛西亚莫。

你知道发烧的妙处吗?
Fever can play a variety of roles, such as inhibiting pathogen replication. It also apparently increases the population of killer T cells of the immune system. Christopher Intagliata reports.
发烧有多种不同的作用，如抑制病菌复制。它还可以显著增加免疫系统中杀伤性T细胞的数量。
I've always thought that when I get a fever, it's my body trying to make things uncomfortable for the invading pathogen. And that's often true—higher temperatures can inhibit the bad guys' ability to replicate. But my fever may actually be a one-two-punch. In addition to slowing down the invader, the heat helps the immune system recruit more troops for a counter-attack. That finding appears in the Journal of Leukocyte Biology.
我很早就知道，发烧的时候，其实是我的身体正在对入侵的病原体做出抵抗。这是事实---高温可以抑制坏病菌复制的能力。但发烧更是一个组合打击。除了减缓病原体的入侵，高温可以帮助免疫系统召集更多的部队做出抵抗。这一研究发表在《白细胞生物学杂志》。
Researchers warmed up one group of mice to body temperatures of about 103 degrees Fahrenheit. They left another group at normal core temperature—about the same as ours. Then they injected both groups of mice with an antigen, a substance that attracts the attention of the immune system.
研究人员将一组老鼠的体温升高到103华氏度，另外一组保持正常体温---大约是人体温度。然后向这两组老鼠的体内注射抗原——一种会引起免疫系统反应的物质。
Blood samples taken three days later revealed that the feverish mice had nearly twice as many killer T-cells: the kind of immune cells that can hunt down infected cells or tumor cells, and slaughter them.
三天后，这两组老鼠的血样表明，体温较高老鼠组体内的杀伤性T细胞是正常组的2倍，这种免疫细胞可以追踪感染细胞或癌细胞，并将其消灭。
So when you're sick and you get the chills, the authors say, your body may be trying to tell you to hop under some blankets. Lie down, warm up and send a message. The heat is on.
所以，当你生病或感到寒冷时，表示你的身体正直向你传达信息--裹条毯子。躺在床上吧，热起来，身体自会做出反应。热度来袭啊。

高考英语阅读理解试题【2】
When you look at yourself in the mirror, do you ever wonder why you look the way you do? Do you also wonder what biological processes were at work to shape your face, which is as indivial and unique as a fingerprint?
The answer is in a little piece of your DNA called a gene enhancer(增强片段),according to scientists at Berkeley Lab. These little pieces6 of DNA help switch on or boost the expression of specific genes, that control the development of the face and head before birth. What's interesting about these little influential bits of DNA is that a gene enhancer doesn't have to be found anywhere close to the genes and, in some cases, doesn't even have to be located on the same chromosome.
Of course, there are a number of hereditary(遗传) factors which help determine appearance, for example, a child resembles a parent. The researchers, who outlined their findings in the journal Science, said the gene enhancer adjusts the genes to give your face its final unique look. Even with look similar but are not exactly the same in appearance.
"Our results suggest that there are thousands of enhancers in the human genome that are involved in facial development," said Axel Visel, a geneticist with Berkeley Lab's Genomics Division, who led the research. "We don't know yet what all of these enhancers do, but we do know that they are out there and they are important for facial development."
Scientists have previously been able to identify some of the genetic faults that can cause birth defects, such as a cleft lip(兔唇), but haven't been able to fully understand what genetic factors are responsible for subtle differences in appearance.
26. The author put forward two questions at the beginning of the passage to ________.
A. expect readers to answer them
B. carry out a survey among readers
C. start a discussion among readers
D. draw readers attention to the topic
27. From Paragraph 3, we know that________.
A. identical twins look similar but not exactly the same
B. hereditary factors determine our appearance completely
C. a child resembles a parent because of afterbirth factors
D. the gene enhancer is something useless and unimportant
28. The underlined word "subtle" in Paragraph 3 is closest in meaning to"___________".
A. not a little
C. not small B. not a bit D. not obvious
29. According to the passage, which statement is NOT true?
A. A cleft lip is a kind of birth defects which are caused by genetic faults.
B. Genetic faults can not be identified and fully understood with today's technology.
C. Gene enhancers have something to do with the facial development according to the research
D. The relation between genetic factors and subtle differences in appearance remains a mystery.
30. Which part of a website is the passage probably taken from?
A. Culture.
C. Science.
B. Opinion. D. Business.

高考英语阅读理解试题【3】
Grown- ups are often surprised by how well they remember something they learned as children but have never practiced ever since. A man who has not had a chance to go swimming for years can still swim as well as ever when he gets back in the water. He can get on a bicycle after many years and still ride away. He can play catch and hit a ball as well as his son. A mother who has not thought about the words for years can teach her daughter the poem that begins “Twinkle, twinkle, little star” or remember the story of Cinderella or Goldilocks and the Three Bears.
One explanation is the law of overlearning, which can be stated as follows: Once we have learned something, additional learning trials increase the length of time we will remember it.
In childhood we usually continue to practice such skills as swimming, bicycle riding, and playing baseball long after we have learned them. We continue to listen to and remind ourselves of words such as “Twinkle, twinkle, little star”and childhood tales such as Cinderella and Goldilocks. We not only learn but overlearn.
The multiplication tables (乘法口诀表) are an exception to the general rule that we forget rather quickly the things that we learn in school, because they are another of the things we overlearn in childhood. The law of overlearning explains why cramming (突击学习) for an examination, though it may result in a passing grade, is not a satisfactory way to learn a college course. By cramming, a student may learn the subject well enough to get by on the examination, but he is likely soon to forget almost everything he learned. A little overlearning, on the other hand, is really necessary for one’s future development.
1. What is the main idea of Paragraph 1?
A. People remember well what they learned in childhood.
B. Children have a better memory than grown- ups
C. Poem reading is a good way to learn words.
D. Stories for children are easy to remember. 2. The author explains the law of overlearning by.
A. presenting research findings
B. setting down general rules
C. making a comparison
D. using examples
3. According to the author, being able to use multiplication tables is
A. a result of overlearning
B. a special case of cramming
C. a skill to deal with math problems
D. a basic step towards advanced studies
4. What is the author’s opinion on cramming?
A. It leads to failure in college exams.
B. It’s helpful only in a limited way.
C. It’s possible to result in poor memory. D. It increases students’learning interest.

生物与环境平衡的危机
The history of life on earth has been a history of interaction between living things and their surroundings. To a large extent, the physical form and the habits of the earth’s vegetation and its animal life have been molded by the environment. Considering the whole span of earthly time, the opposite effect, in which life actually modifies its surroundings, has been relatively slight. Only in the present century has one species man acquired significant power to alter the nature of his world.
During the past quarter century this power has not only become increasingly great but it has changed in character. The most alarming of all man’s assaults upon the environment is the contamination of air, earth, rivers, and sea with dangerous and even lethal materials. This pollution is for the most part irrecoverable. In this now universal contamination of the environment, chemicals are the sinister partners of radiation in changing the very nature of the world the very nature of its life. Chemicals sprayed on croplands or forests or gardens lie long in soil, entering into living organisms, passing from one to another in a chain of poisoning and death. Or they pass mysteriously by underground streams until they emerge and combine into new forms that kill vegetation, sicken cattle, and work unknown harm on those who drink from once pure wells. "Man can hardly even recognize the devils of his own creation," as a scientist has said.
It took hundreds of millions of years to proce the life that now inhabits the earth. Given time not in years but in millennia life adjusts, and a balance has been reached. But in the modern world there is no time.
The rapidity of change follows the impetuous pace of man rather than the deliberate pace of nature. Radiation is now the unnatural creation of man’s tampering with the atom. The chemicals are the synthetic5 creations of man’s inventive mind, having no counterparts in nature.
To adjust to these chemicals would require not merely the years of a man’s life but the life of generations. And even this, were it by some miracle possible, would be futile, for the new chemicals come from our laboratories in an endless stream; almost five hundred annually find their way into actual use in the United States alone. Among them are many that are used in man’s war against nature. Since the mid 1940’s over 200 basic chemicals have been created for use in killing insects, weeds, and other organisms described as "pests."
It is not my contention that chemical insecticides must never be used. I do contend that we have put poisonous and biologically potent chemicals indiscriminately into the hands of persons largely or wholly ignorant of their potentials for harm. We have subjected enormous numbers of people to contact with these poisons, without their consent and often without their knowledge. I contend, furthermore, that we have allowed these chemicals to be used with little or no advance investigation of their effect on soil, water, wildlife, and man himself. Future generations are unlikely to forgive our lack of concern for the integrity of the natural world that supports all life.
地球上生命的历史一直就是一部生物与其环境相互作用的历史。在很大程度上，地球上动植物的形态以及习性都是由外部环境所塑造的。考虑到地球上生命存在的整个时间，相反作用，即生命对其周围环境的实际改变作用，却相对很小。只有在当前这个世纪(指20世纪)才有一个物种--人类，获得了强大的力量，改变了其所生存的世界的自然状态。
在过去的1/4世纪中，这种力量不仅日趋强大，而且其性质也发生了变化。在人类破坏环境的种种行为中，最令人担忧的是人类向大气、土壤、河流以及海洋中排放危险甚至致命物质，而当今这种污染在很大程度上是无法挽救的。在当今这种对环境的普遍污染中，化学制品与辐射狼狈为奸，改变着地球的自然状态，也就是改变着地球上生命的自然状态。喷洒到农田、森林或者花园里的化学物质长期滞留于土壤中，渗入有机体内，并彼此相传，形成了一个中毒与死亡的链条。化学物质还神秘地通过地下水传递，最终以新的形式出现并结合，使植物毒死，牲畜害病，并使饮用一度纯净的井水的人遭受了不明之害。正如一位科学家所言：“人类甚至对自己创造的恶魔都不认识。”
地球历经了许多亿年才创造了栖息其上的生命。经过了一定时间--不是以若干年计而是以若干千年计的时间--生命开始适应环境，并形成了一种与环境的平衡。但是在现代世界中，时间这一因素已经没有了。
环境改变的速度不再顺从大自然从容不迫的节奏，而是顺从人类急切匆匆的步伐。辐射是当今人类通过支配原子而得到的一种非自然的创造物。化学制品则是人类有发明创造力的头脑创造出来的合成物，在自然界本无相应的东西。
为了适应这些化学制品，人类需要付出的时间不会只是一个人一生的时间，而是几代人的时间。而即使这样，就算出现奇迹成为可能，这种适应也是徒劳的，因为新的化学制品从我们的实验室中源源不断地涌出。仅在美国，每年就有大约500种化学制品投入使用，其中许多是用于人类对自然的战争中。从20世纪40年代中期起，人类已经创造了200多种基本化学制品用来消灭昆虫、野草以及其他所谓的“有害生物”。
我不是说人类决不能使用化学杀虫剂。我要说的是，我们不分青红皂白地将这些有毒的、具有强大生物功能的化学制品，交给了那些对这些制品的潜在危害基本上或者完全无知的人去使用。我们使众多的人接触这些有毒物质，却没有征得他们的同意，并常常将他们蒙在鼓中。我还要说的一点是，我们允许使用这些化学制品，却事先很少或者根本没有调查它们对土壤、水、野生生物以及人类自身造成的影响。我们缺乏对万物赖以生存的自然界生态统一的关心，对此，我们的后代是不可能原谅的。

基因技术能否使人更聪明?Get Smart
Many people dream of having a smarter brain. Princeton neurobiologist Joseph Z. Tsien found the key. In September he announced that he’d built a better mouse by altering a gene that affects learning and memory. A similar process of gene manipulation might conceivably be used one day to boost intelligence in humans.
The secret lies in a feature of brain cells called the nmda receptor, which Tsien likens[1] to a cylindrical tube or window that mediates[2] the flow of information. When the window is open, chemicals called neurotransmitters flow through easily and memory is registered and stored. But as organisms mature, the window begins to close. (This may explain why children lose their facility for learning new languages when they reach sexual maturity and why some people suffer memory loss as they age.)
Tsien noticed that the receptor worked more efficiently when teamed[3] with the gene NR2B, so he introced extra NR2B genes into a batch of fertilized mouse eggs. In a normal mouse, the memory window is open for just 150-thousandths of a second. In Tsien’s specially engineered mice, the window opens for 250-thousandths of a second, long enough to make a remarkable difference in memory retention. When he pitted[4] his mice against common mice, they won paws down. Ordinary mice could recognize a Lego block for 12 hours, but smart mice could remember the block for up to three days. "That’s a profound enhancement," Tsien says.
Can it be done with humans? Maybe, but genetic engineering will have to make some extraordinary advances first. And some thorny ethical issues will have to be resolved. Meanwhile, Tsien promises to keep his furry little geniuses locked up in a lab, far from your larder. "Otherwise," he says, "you might need a smart cat or a smart mousetrap to catch them."
许多人都希望自己能变成更聪明。普林斯顿神经生物学家Joseph Z. Tsien就找到了这把开启智慧之门的钥匙：他于九月宣布，通过改变影响学习和记忆能力的基因培养出了一只聪明的老鼠。类似的基因处理技术有望在未来日子里运用到人脑，以推动人类智慧的飞跃。
该技术的奥秘就在于名为nmda感受器的脑细胞的功能。Tsien将其比作一个传递信息流的圆柱通道或窗口。当窗口开放时，某种称为神经传递素的化学物质就能轻易流过，记忆因此登记并存储了下来。然而，当器官成熟时，这扇窗口就开始关闭。(这也能解释为何 儿童 长大后(性器官成熟之时)会失去掌握新语言的能力，以及为何某些人年老时会患失忆)。
Tsien注意到，当感受器与名为NR2B的基因协作时效率会更高。因此，他将NR2B基因植入一批老鼠的受精卵中。一只普通老鼠的记忆之窗仅开放千分之150秒。而经Tsien植入基因的老鼠，记忆之窗能开放千分之250秒，这已经能够使其 记忆力 发生惊人的改变。当他让自己的老鼠与普通老鼠互斗时，它们竟能轻而易举地取胜。普通老鼠能够保留关于Lego block的记忆12小时，而聪明的老鼠居然能将记忆保持三天。“这可是一个意义深远的进步。”Tsien这样说。
那么，人类也能接受这种基因移植吗? 或许可以，但前提是基因工程得首先做出非凡的成就，还必须解决一系列棘手的伦理问题。Tsien保证他一定会将那些披着毛皮的小天才锁入实验室，远离人们的食品柜。“否则，”他说，“为了捉住他们，人们就不得不去寻找更聪明的猫或者功能更强的捕鼠器了。”

食用转基因食品安全吗?Food Safe To Eat?
Traditional plant breeding involve s crossing varieties of the same species in ways they could cross naturally.For example，disease-resistant varieties of wheat have been crossed with high-yield wheat to combine these properties.This type of natural gene exchange is safe and fairly predictable.
Genetic engineering(GE)involves exchanging genes between unrelated species that cannot naturally exchange genes with each other.GE can involve the exchange of genes between vastly different species――e.g.putting scorpion toxin genes into maize or fish antifreeze genes into tomatoes.It is possible that a scorpion toxin gene，even when it is in maize DNA，will still get the organism to proce scorpion toxin――but what other effects may it have in this alien environment?We are already seeing this problem――adding human growth hormone genes to pigs certainly makes them grow――but it also gives them arthritis and makes them cross-eyed，which was entirely unpredictable.
It will be obvious，for example，that the gene for human intelligence will not have the same effect if inserted into cabbage DNA as it had in human DNA――but what side-effect would it have?In other words，is GM food safe to eat?The answer is that nobody knows because long-term tests have not been carried out.
Companies wanting a GM proct approved in the UK or USA are required to provide regulatory bodies with results of their own safety tests.Monsanto’s soya beans were apparently fed to fish for10weeks before being approved.There was no requirement for independent testing，for long-term testing，for testing on humans or testing for specific dangers to children or allergic people.
The current position of the UK Government is that“ There is no evidence of long-term dangers from GM foods.”In the US，the American Food and Drug Administration is currently being prosecuted for covering up research that suggested possible risks from GM foods.
传统的植物培育 方法 ，是依照植物自然杂交的方式，进行相同物种的人工杂交。比如，抗病小麦同高产小麦杂交，形成了一种具有双重特性的新的小麦品种。这种自然的基因交换既安全，又具有相当的可预见性。
基因工程是在彼此毫无关系的物种之间，相互交换在自然条件下无法交换的基因。它可在有巨大差异的物种之间进行基因交换。比如，将蝎子毒素基因注入玉米，或者将鱼防冻基因注入西红柿。即使在玉米DNA中，蝎子毒素基因依然可能获得有机组织产生蝎子毒素。但是在这种异质的环境中，这种基因产品会有什么其他作用吗?我们实际上已经发现这个问题：将人类生长荷尔蒙基因植入猪的体内，一定会使猪的生长加速，但是同时也使猪患上了关节炎和内斜视，而这一切是完全无法预测的。
打个比方，人类的智力基因显而易见在人体DNA内和注入卷心菜DNA后的作用是不同的。但将它植入卷心菜中会产生什么样的副作用呢?换句话说，食用转基因食品安全吗?没有人知道答案，因为人们尚未进行长期的测试。
在英国或者美国，一个公司如果希望其转基因产品获得批准，它必须向管理机构提供本公司转基因产品安全测试的结果。Monsanto的大豆在获得批准之前，曾用了10周时间进行喂鱼试验。目前，尚无要求对转基因产品进行独立测试、长期测试、人体测试，或者就其对儿童及过敏者所造成的特定危险进行测试。
英国政府目前的态度是：“尚无证据表明食用转基因食品存在长期性的危险。”在美国，人们正在起诉美国食品药品管理局掩盖转基因食品安全性的研究结果，这些研究结果表明，食用转基因食品可能导致危险。

英语科普文章选——2004年十大科学发现
不久前，著名的《科学》杂志评选出2004年最重要的十大科学发现。这些发现中既有人类对神秘宇宙太空的探索，也有对身边熟悉事物的新发现。无论是何种的科学探索和发现，人类求知的愿望和动力永远都在推动社会的发展和进步。
Water and robots on Mars chosen as tops in 2004 by 'Science'
WASHINGTON — The conclusive discovery by a pair of wheeled robots that Mars once had vast pools of water and possibly could have harbored life was chosen by the editors of the journal Science as the most important scientific achievement of 2004.
Scientists announced in March that the Mars once played host to salty seas. This Mars Express image indicates water erosion.
NASA's two Mars rovers（漫游者）Opportunity and Spirit, landed on the Red Planet early in 2004 and have since found clear and conclusive evidence that Mars was drenched with（浸透） water at some time in its history.
The editors of Science, one of the world's leading publishers of peer-reviewed, original research, judged the robotic accomplishment as the top scientific "Breakthrough of the Year."
"Inanimate, wheeled, one-armed boxes roaming another planet have done something no human has ever managed," Science reported in this week's edition. "They have discovered another place in the universe where life could once have existed."
Nine other scientific achievements, including discovery of another species of human, were selected as runners-up, but Science editor-in-chief Donald Kennedy said "there wasn't much doubt about this year's winner."
Opportunity and Spirit found unmistakable proof of Martian water: rippled sediments（沉积物） that were once at the bottom of a shallow sea, and rock that once was so water-soaked that "it had rotted," the journal said.
"Their finds mark a milestone in humankind's search for life elsewhere in the universe," Science said.
Kennedy said one of the most important messages from the remote exploration is "the extraordinary efficiency of these robot missions."
He said it is clear that the National Aeronautics and Space Administration must not abandon its robotic exploration while gearing up for President Bush's program to send humans to the moon and later to Mars.
"To do one at the expense of the other would be a mistake," Kennedy said. "It remains to be demonstrated what a human exploration could do that we can't do now or couldn't do in the next 10 years with robotic technology."
The first runner-up for breakthrough of the year was the discovery on the Indonesian island of Flores of fossils from a species of tiny humans who stood about 3 feet tall and had a brain less than a third the size of modern humans. Yet, the diminutive（小的） hominid（原始人） lived about 18,000 years ago. This suggests that Homo floresiensis shared the Earth with Homo sapiens（人类）, or modern people. Science said some described the find as "the biggest discovery in half a century of anthropological research."
Third on Science's list of 2004 breakthroughs was the cloning of human embryos by South Korean researcher Woo San Hwang and his colleagues. The work was not an attempt to genetically plicate a human. Instead, the researchers hoped to make embryonic stem cells for research purposes. Although many other mammals have been cloned, the work was the first to demonstrate that cloning techniques would work with human cells.
Following are the rest of Science's 2004 selections.
4. U.S. and Austrian scientists created a new form of condensate（冷凝物）, an ultracold gas that slips into a quantum state where a group of atoms act as a single superatom. The achievement was notable because it used fermions（费米子）, a class of atoms with a nuclear structure that makes it difficult to create a condensate.
5. Scientists discovered that "junk DNA," the base pairs between known genes in the human genetic structure, play an important role. Several research teams have found that DNA between genes helps determine how vigorously and often the genes are activated and shapes the coding for protein proction.
6. Astronomers discovered a pair of neutron stars（中子星） locked in orbit of each other and spewing out beams of radiation. Both objects are pulsars（脉冲星）, rapidly flickering on and off with pulses of energy. One object is pulsing at the rate of 44 times a second. By studying the radiation, astronomers hope for the first time to learn about the density of matter within a neutron star.
7. Naturalists tracking the fate of wild species worldwide reported bad news. A survey of amphibians（两栖动物） found that of 5,700 known species, about 30% were at risk of extinction. A survey in the United Kingdom found that butterflies, songbirds and native plant species are all losing ground in the battle for species survival.
8. It is one of the most common and universally known substances, but researchers are still learning more about water. Several teams of researchers made new discoveries about how water molecules（分子） bind together and how electrons（电子） and protons（质子） dissolve in water. Some of the findings are questioned and Science noted: "Water still gives researchers much to scratch their heads about."
9. A new form of research and aid is creating "a revolution in public health," said Science. The partnership of public and private organizations worldwide is changing the way drugs are developed, tested and distributed to the poorest nations on Earth, the journal said. Researchers tallied at least 92 public-private partnerships worldwide attacking such diseases as malaria, tuberculosis and HIV.
10. Researchers have developed techniques to identify genes in ocean water or in specimens recovered from deep underground. Thousands of new genes have been found. By sequencing these genes, researchers hope to identify news species and, perhaps, learn how organisms survive in harsh and forbidding locations on Earth.

『玖』 关于低碳生活或绿色科技的英语科普类文章
Recently, my classmates and I participated in the activity of Low – Carbon Living organized by the WWF. On the first day, we chose to go to school by bike or on foot rather than by bus or car. Before we left the classroom, we made sure the lights and the computer were switched off. In order to make full use of paper, we began to write on both sides. Besides, while shopping, we no longer used plastic bags but carried environmentally friendly ones. From joozone.com.
I think what we did on that day was meaningful, which an help us to form. a good habit. We should also call on the people around us to do something for low – carbon living. Only in this way will the earth he a good place to live on.
最近，我和我的同学们参加了–低碳生活组织世界自然基金会的活动。在第一天，我们选择去骑自行车或步行而不是乘公共汽车或汽车学院。我们离开教室之前，我们确保灯和电脑被关闭。为了充分利用纸张，我们开始写的两边。此外，在购物时，我们不再使用塑料袋，但是环保。爱戴。
我认为我们所做的，都是有意义的，它帮助我们形成。一个好的习惯。我们应该呼吁我们周围的人们为低碳生活–做某事。只有用这种方式将地球他生活的好地方。
