❷ 大学英语段落，求翻译，一定要语言通顺
中国股市是否已抄出现泡沫？这取袭决于你看股市的哪一部分。对于长期萎靡的大盘股来说，经过过去几年的长期低迷之后，目前毫无疑问其股价表现得更加公允。许多银行股的股价也仍然低于国际同业银行机构的股价。不过对于创业板（主要为初创公司上市融资）来说，情况就不是这样了，尤其是高科技企业，其市盈率已高达130，比那些迅速成长的普通公司的市盈率高出二倍有余。创业板被看做是中国的纳斯达克；而当前创业板的状况也的确很像1999年时纳斯达克的状况——那是全球网络泡沫崩溃的前夕。
中国股市经常被称为一个大赌场，股价与其背后的经济状况完全扯不上关系。虽然股价在过去的经济增长中并没有什么像样的抬升，但是过去几个月这种股价与经济的背离又向着相反的方向达到了一个新的极致。（中国）一季度的经济增速回落到7%，创下六年来的新低；但股市自去年年中以来却已经翻了个番。（随着中国的经济政策逐渐转向）货币宽松和财政刺激——以及对两种经济工具兼而有之的期盼——大概能够解释为什么会引发这一次的牛市。但是随着本轮牛市持续的时间越长，其表现就越像一个典型的非理性繁荣状况。因此，我们用图表数据来展示一下当前这种狂热的股市。
❸ 如何讲大学英语精读
所谓精读，就是要精讲。
讲什么呢：讲语言。
你可以从小讲到大，比如，先讲专重要的单词属（key words）；然后讲词组或短语；接着讲句子；最后讲整篇。
这里面渗透了词法、句法和修辞等东西，所以你事先要研究一番这些概念。
也可以由大讲到小（我觉得这样讲比较好）。先把重点放在全文，让学生们给一个梗概；然后，分段落展开（每段落的中心市什么），当然要有学生们讨论；再讲作者是如何用各个句子展现这个中心的（其中最关键的是每段的主体句）。
❹ 如何讲一节大学英语课，时间是20分钟，没有学生，就是事业编考试的试讲环节，没有题目和具体内容。
大学抄英语教材袭一般是大学英语，你可以选择大一大学英语课本里的几篇篇文章的某一个段落进行准备。如果面试时候老师不给材料现场准备就讲自己准备好的。不过，一般都会现场给你题目和内容的。
一般试讲都是没有学生的，面对的只有评审老师，你要把他们当成学生，进行一些有效互动，但是不要等着台下老师的回应，继续你的讲课就可以了。
体态仪容仪表也很重要，不要有过多的小动作，发音一定要标准，淡定从容。
❺ 怎样写好英语段落
段落是文章的缩影。写好了段落，就能比较成功地写出较好的文章。经过中学英语基础阶段的学习之后，大学英语的写作重点就从选词造句转移到了联句成段和联段成篇上。进行段落层次上的写作训练，是写好英语文章的关键一环。下面介绍的是段落结构。
段落（ paragraph ）是由表达单一中心思想（controlling idea or central idea ）的一组句子（包括主题句 topic sentence,推展句supporting sentences及结论句concluding sentence）构成，是文章结构的基本独立单位。本讲我们将就主题句和中心思想这两个方面展开讨论。
主题句与推展句
1． 主题句
主题句（topic sentence）是表达段落主题的句子。它用以概括段落大意，要求全段其他文字都围绕它展开。请看下例：
My mother has passed along to me certain rules for getting along with others. Don't argue with parents; they will think you don't love them. Don't argue with children; they will think themselves victimized. Don't argue with spouses; they will think you are a tiresome mate. Don't argue with strangers; they will think you are not friendly. My mother's rules, in fact, can be summed up in two words: Don't argue.
主题句中提出的 "certain rules" 指的是什么？展开句中通过四个 "Don't argue --" 逐一加以交代。从结构来看，这是一个比较典型的段落，它包括了主题句，推展句和结论句（即本段中的末句）。
1．1 主题句的位置
主题句通常放在段落的开端，其特点是开门见山地摆出问题，然后加以详细说明。其作用是使文章的结构更清晰，更具说服力，便于读者迅速地把握主题和想象全段的内容。主题句可以放在段中起到承上启下的作用，或放在段尾起概括全段的作用。但初学者比较难于掌握，因而在四级考试中，考生应尽量采用将主题句放在段落开头的写作手法。
例1: Our life today depends very much on energy. In towns and in villages, on farms and in factories, machines have made life easier than it used to be. The machines use energy, and energy is needed for heating, lighting, communications, carrying goods -- everything. Factories and instrial plants use a great deal of energy to make the things that we use and buy and sell.
这段文字所讲的主要是能源问题。第一句就概括性地提出“我们目前的生活很大程度上依赖于能源”。而随后出现的三句都是具体事例，对第一句进行说明和论述。我们可以断定第一句为该段的主题句（斜体部分）。
例2: （主题句）No one can avoid being influenced by advertisements. （推展句1）Much as we may pride ourselves on our good taste, we are no longer free to choose the things we want, for advertising exerts a subtle influence on us. （推展句2）In their efforts to persuade us to buy this or that proct, advertisers have made a close study of human nature and have classified all our little weakness.
以上这段由三句话组成。第一句是主题句，直截了当指出无人不受广告影响这个主题，接着列举两个推展句对其补充和支持，指出我们已无法自由选择所需的商品，理由是广告商已仔细研究了我们
❻ 大学英语课文该怎么讲给学生听,作为一名新大学老师求助！
英语要学好，注意，是学“好”，主要不是靠上课，有时甚至可以基本忽略上课的内作用。原因第一是个人容努力占最大比重，第二就是大部分老师上的是混日子的课，对学生帮助很少，味同嚼蜡。
你不错啊，因为你确实在考虑怎么去讲“有意思”的课。很好的开始。
要讲好一堂课，作为老师，也是学无止境。
作为良好开始的基础：大学英语的话，知识点肯定要讲一讲的。课文内容不需要翻译给学生。但是要讲解其中的精妙处。然后设置一些课堂讨论，然后在学了一阵以后可以请同学朗读某一个精彩段落之类。
至于其他的，等上面的内容做好了，再改进。
你可以参考一下新东方讲新概念的视频。有很多课很精彩的。如果你要成为一个优秀的老师，可以学习借鉴一下。还可以去参加新东方专门培训老师的课程。
❼ 大学英语精读怎么讲解
翻译课文，讲难句子的句法，讲重点单词。我们老师是这样讲的
❽ 怎样写好英语段落（二）
段落发展的手段及结尾段的写法 在上一讲我们讲了主题句，推展句的写法；这一讲我们要进一步来谈一谈段落发展的几种手段以及结尾段的写法。 段落发展的几种手段 1． 列举法(details) 作者运用列举法，是通过列举一系列的论据对topic sentence中摆出的论点进行广泛、全面地陈述或解释，列举的顺序可以按照所列各点内容的相对重要性、时间、空间等进行。 Yesterday was one of those awful days for me when everything I did went wrong. First, I didn't hear my alarm clock and arrived late for work. Then, I didn't read my diary properly and forgot to get to an important meeting with my boss. During the coffee break, I dropped my coffee cup and spoilt my new skirt. At lunch time, I left my purse on a bus and lost all the money that was in it. After lunch, my boss was angry because I hadn't gone to the meeting. Then I didn't notice a sign on a door that said "Wet Paint" and so I spoilt my jacket too. When I got home I couldn't get into my flat because I had left my key in my office. So I broke a window to get in and cut my hand. 根据本段主题句中的关键词组everything I did went wrong，作者列举了8点内容，分别由first, then, ring the coffee break, after lunch time等连接词语引出，使得该文条理清楚、脉络分明、内容连贯。 常用于列举法的过渡连接词有：for one thing , for another, finally, besides, moreover, one another , still another, first, second, also等。 2. 举例法(example) 作者通过举出具体事例来阐述、说明主题句的内容，严格地讲，举例法也是列举法的一种，它们的区别在于：列举法侧重罗列事实，所列事实力求全面；而举例法侧重通过举出典型事例来解释作者观点，且事例可多可少。 我们来看下面这个用举例法展开的段落。 There are many different forms of exercises to suit different tastes. For example, those who enjoy competitive sports may take up ball games. For another example, if they prefer to exercise alone, they can have a run or take a walk in the morning or in the evening. Besides, people can go swimming in the summer and go skating in the winter. In short, no matter what their interests are, people can always find more than one sports that are suitable to them. 本段采用了三个事例来说明主题句中的关键词组different forms of exercises，这三个例子分别由连接词for example, for another example 和 besides引出，最后由引导的结尾句总结全段内容。 举例法中常用的连接词有：for example (instance), one example is, besides, furthermore, moreover, in addition等。 3. 叙述法(narration) 叙述法发展段落主要是按照事物本身的时间或空间的排列顺序，通过对一些特有过渡连接词的使用，有层次分步骤地表达主题句的一种写作手段。用这种方法展开段落，作者能够清楚连贯地交待事物的本末，从而可以使读者可以清晰、完整地理解文章的含义，例如： In the flat opposite, a woman heard the noise outside. When she looked out through the window, she discovered that her neighbor was threatened by someone. She immediately called the police station. In answer to the call, a patrol police car arrived at the scene of the crime quickly. Three policemen went inside the flat at once, and others guarded outside the building to prevent anyone from escaping. 这段是按照事物发展的先后顺序，叙述从发现案情、报警、到警察赶到、包围现场的过程。全文脉络清晰，叙述的层次感强，结构紧凑。 常用于叙述法中的过渡连接词有：first, an the beginning, to start with, after that, later, then, afterwards, in the end, finally等。 4． 对比法或比较法(comparison & contrast) 将同类的事物按照某种特定的规则进行比较分析是一种常用的思维方法。通过对比，更容易阐述所述对象之间的异同和优缺点，例如： The heart of an electronic computer lies in its vacuum tubes, or transistors. Its electronic circuits work a thousand times faster than the nicer cells in the human brain. A problem that might take a human being a long time to solve can be solved by a computer in one minute. 在这段文字上， 作者为了突出电子计算机运行速度之快，首先将它与人脑进行了比较， "-- a thousand times faster than --" ;而后，又将这一概念具体到了 "a problem"上，通过对比使读者从 "-- a long time -- in one minute"上有更加直观的认识。 常用于对本法或比较法上的过渡连接词有：than, compared with等。 5． 分类法(classification) 在阐述某一概念的段落中，常用分类法。通过对概念中所包括的事物进行分门别类，分别加以叙述，使读者有更为清晰的认识，如： Ever since humans have lived on the earth, they have made use of various forms of communication. Generally, this expression of thoughts and feelings has been in the form of oral speech. When there is a language barrier, communication is accomplished through sign language in which motions stand for letters, words and ideas. Tourists and the people unable to hear or speak have had to resort to this form of expression. Many of these symbols of whole words are very vivid and exact and can be used internationally; spelling, however, cannot. Body language transmits ideas or thoughts by certain actions, either intentionally or unintentionally. A nod signifies approval, while shaking the head indicates a negative reaction. Other forms of nonlinguistic language can be found in signal flags, Morse code, and picture signs. 在该段中为了说明topic sentence中的 "various forms of communication"，作者将其分为oral speech, sign language, body language及other forms of nonlinguistic language，并逐加阐述。 采用这种方法的段落并没有标志突出的连接词，所述各项均为平行并列关系，所以没有明显的主次之分。 6．因果分析法(cause and effect) 在阐述某一现象的段落中，常采用因果分析法。例如： The role of women in today's society is changing. One reason is that women have begun to assert themselves as independent people through the women's movement. Also, women are aware of the alternatives to staying at home. Another reason is that increasing numbers of women who enter new fields and interests serve as role models for other women. Moreover, men are becoming more conscious of the abilities of women and have begun to view their independence positively. 本段中，主题句提出了一种社会现象，推展句则对产生这种现象的原因作出各种解释。 常用于因果分析法的连接词有：because, so, as a result等。 7． 定义法(definition) 在科普文章的写作中，定义法是必不可少的。通过下定义，可以使读者对该事物有一个更直接的认识。 Automation refers to the introction of electronic control and automation operation of proctive machinery. It reces the human factors, mental and physical, in proction, and is designed to make possible the manufacture of more goods with fewer workers. The development of automation in American instry has been called the "Second Instrial Revolution". 这一段文字使我们了解了 "automation" 和 "Second Instrial Revolution" 两个概念，分别由 "refers to" 和 "been called" 引出。 常出现在定义法中的词语有：refer to, mean, call等。 8. 重复法(repetition) 句子的一部分反复出现在段落中，这就是重复法。它往往造成一种步步紧逼的气氛，使文章结构紧凑，有感染力。比如： Since that time, which is far enough away from now, I have often thought that few people know what secrecy there is in the young, under terror. I was in mortal terror of the young man who wanted my heart and liver; I was in mortal terror of my interlocutor with the iron leg; I was in mortal terror of myself, from whom an awful promise had been extracted; -- 该段中反复应用了I was in mortal terror of …我经常处于恐怖之中。 以上， 我们结合具体文章讨论了展开段落的几种方法。在实际写作中，我们往往不必拘泥于一种写作方法，而是将若干方法穿插在一起，使文章有声有色。 结尾段 我们知道文章的开头很重要，因为好的开头可以吸引读者、抓住读者的注意力。同样，文章的结尾也很重要，好的结尾会使读者对全文的中心思想留下深刻的印象，可以增添文章的效果和说服力，让人深思，回味无穷。确切地说，结尾的作用就是概括全文内容，进一步强调或肯定文章的中心思想，使读者加深印象；有时也用于展望未来，提出今后方向或令人深思的问题给读者留下回味和思考的余地。 但是，如何才能写好英文短文的结尾呢? 下面就介绍几种写结尾段最常用的方法： 1．重复中心思想: 回到文章开头阐明的中心思想或主题句上，达到再次肯定和强调的效果。 (例1)A sense of humor is really one of the keys to happiness. It gives zest to life to make it worth living. (例2)With all these benefits, it is no wonder that sports and games have now become more popular with people than ever. 2．作出结论: 文章最后用几句话概括全文内容，并进一步肯定文章的中心思想或作者的观点。 (例1)In conclusion, a good teacher-student relationship can be mutual beneficial. The students gain knowledge eagerly and enjoyably, and the teacher gains satisfaction from his job. (例2)On the whole there are more advantages than disadvantages in the use of TV. Yet different people may have different attitude toward TV. But we must realize that television in itself is neither good nor bad. Its value to people and society depends on how we look at it. 3．应用引语: 用格言、谚语或习语总结全文，既言简意赅又有更强的说服力。 (例1)If you have anything to do, try to do it yourself, for that is the safest way to
permanent success. Remember the famous saying. "God helps those who help themselves." (例2)If we stick to studies day after day, there is nothing that can't be achieved. As an old saying goes: "Constant dropping of water wears away a stone." 4．用反问结尾: 虽然形式是问句，但意义却是肯定的，具有明显的强调作用，引起读者思考。 (例1)Therefore, listening skills must be consciously improved. Since it is such an important means of learning and communication, why should we not develop this ability as far as possible? (例2)So，what can we benefit from wealth if we do not have health? 5．提出展望或期望: 表示对将来的展望或期待读者投入行动。 (例1)I am sure that Chinese will become one of the most important languages in the world in the next century. As China will open further to the outside world the language is sure to be spread world widely. (例2) If everyone has developed good manners, people will form a more harmonious relation. If everyone behaves considerately towards others and social ethics people will live in a better world. With the general mood of society improved, there will be a progress of civilization. 以上介绍了几种写结尾段最常用的方法，但到底选择何种方法结尾还得根据文体来决定。平铺直叙的记叙文，往往在故事或事实情节讲完时文章也就自然结束了，而说理性和逻辑性较强的说明文和议论文都应有一个正式的结尾。希望以上介绍的几种方法能对大家写好结尾有所帮助。 首先，一个段落必须有一个中心即主题思想，该中心由主题句特别是其中的题旨来表达。整个段落必须紧扣这个主题(stick or hold to the topic)，这就是段落的统一性(unity)。其次，一个段落必须有若干推展句，使主题思想得到充分展开，从而给读者一个完整的感觉，这就是完整性(completeness or adequateness)。再者，一个段落不是杂乱无章的，而是有机的组合，句子的排列顺序必须合乎逻辑，从一个句子到另一个句子的过渡必须流畅(smooth)，这就是连贯性(coherence)。下面我们就对这三个标准分别加以说明。 1. 统一性 一个段落内的各个句子必须从属于一个中心，任何游离于中心思想之外的句子都是不可取的。请看下例： Joe and I decided to take the long trip we'd always wanted across the country. We were like young kids buying our camper and stocking it with all the necessities of life. Bella bakes the best rhubarb pie. We started out in early spring from Minneapolis and headed west across the northern part of the country. We both enjoyed those people we met at the trailer park. Joe received a watch at his retirement dinner. To our surprise, we found that we liked the warm southern regions very much, and so we decided to stay here in New Mexico. 本段的主题句是段首句，controlling idea（中心思想）是take the long trip across the country。文中出现两个irrelevant sentences，一个是Bella bakes the best rhubarb pie，这一段是讲的是Joe and I，中间出现一个Bella是不合适的。还有，Joe received a watch at his retirement dinner这一句更是与主题句不相关。考生在四级统考的作文卷上常常因为造出irrelevant sentences（不相关语句）而丢分，值得引起注意。再看一个例子： My name is Roseanna, and I like to keep physically fit. I used to weigh two hundred pounds, but I joined the YMCA for an exercise class and diet program. In one year I lost eighty pounds. I feel much better and never want to have that much weight on my five-feet frame again. I bought two new suitcases last week. Every day I practice jogging three miles, swimming fifteen laps, lifting twenty-pound weights and playing tennis for one hour. My mother was a premature baby. 本段的controlling idea 是like to deep physically fit，但段中有两个irrelevant sentences，一个是I bought two new suitcases last week，另一个是My mother was a premature baby。 从上面两个例子可以看出，native speakers同样会造出来irrelevant sentences。卷面上如果这种句子多了，造成偏题或离题，那问题就更严重了。权责声明：本站所有音乐均网上搜集仅做宽带测试，任何涉及商业盈利目的均不得使用，否则后果自负！如遇英文歌曲不能播放，系歌曲链接失效，请谅解！本站全部英文歌曲的所有权归其唱片公司或歌手所有。请购买正版英文歌曲支持你的偶像！
❾ 英语老师叫我们上去讲解课文段落，应该从哪些方面入手呢

如果你的意思是如何写好一个段落，那么请继续往下看
首先，一个段落必须有一个中心即主题思想，该中心由主题句特别是其中的题旨来表达。整个段落必须紧扣这个主题（stick or hold to the topic），这就是段落的统一性（unity）。其次，一个段落必须有若干推展句，使主题思想得到充分展开，从而给读者一个完整的感觉，这就是完整性（completeness or adequateness）。再者，一个段落不是杂乱无章的，而是有机的组合，句子的排列顺序必须合乎逻辑，从一个句子到另一个句子的过渡必须流畅（smooth），这就是连贯性（coherence）。下面我们就对这三个标准分别加以说明。
1、统一性
一个段落内的各个句子必须从属于一个中心，任何游离于中心思想之外的句子都是不可取的。请看下例：
Joe and I decided to take the long trip we’d always wanted across the country. We were like young kids buying our camper and stocking it with all the necessities of life. Bella bakes the best rhubarb pie. We started out in early spring from Minneapolis and headed west across the northern part of the country. We both enjoyed those people we met at the trailer park. Joe received a watch at his retirement dinner. To our surprise, we found that we liked the warm southern regions very much, and so we decided to stay here in New Mexico.
本段的主题句是段首句，controlling idea（中心思想）是take the long trip across the country。文中出现两个irrelevant sentences，一个是Bella bakes the best rhubarb pie，这一段是讲的是Joe and I ，中间出现一个Bella是不合适的。还有，Joe received a watch at his retirement dinner这一句更是与主题句不相关。考生在四级统考的作文卷上常常因为造出irrelevant sentences（不相关语句）而丢分，值得引起注意。再看一个例子：
My name is Roseanna, and I like to keep physically fit. I used to weigh two hundred pounds, but I joined the YMCA for an exercise class and diet program. In one year I lost eighty pounds. I feel much better and never want to have that much weight on my five-feet frame again. I bought two new suitcases last week. Everyday I practice jogging three miles, swimming fifteen laps, lifting twenty-pound weights and playing tennis for one hour. My mother was a premature baby.
本段的controlling idea 是like to deep physically fit，但段中有两个irrelevant sentences，一个是I bought two new suitcases last week，另一个是My mother was a premature baby。
从上面两个例子可以看出，native speakers同样会造出来irrelevant sentences。卷面上如果这种句子多了，造成偏题或离题，那问题就更严重了。
2、完整性
正象我们前面说得那样，一个段落的主题思想靠推展句来实现，如果只有主题句而没有推展句来进一步交待和充实，就不能构成一个完整的段落。同样，虽然有推展句，但主题思想没有得到相对圆满的交待，给读者一种意犹未尽的感觉。这样的段落也不能完成其交际功能。例如：
Physical work can be a useful form of therapy for a mind in turmoil. Work concentrates your thoughts on a concrete task. Besides, it is more useful to work ---- you proce something rather than more anxiety or depression.
本段的主题句是段首句。本段的两个推展句均不能回答主题句中提出的问题。什么是“a mind in turmoil”（心境不平静）Physical work又如何能改变这种情况？为什么它能起therapy的作用？读者得不到明确的答案。由于四级统考的作文部分只要求写一篇100～120个词的三段式短文，每一段只有大约40个词左右，因此，要达到完整就必须尽可能地简明。例如：
It is not always true that a good picture is worth a thousand words. Often writing is much clearer than a picture. It is sometimes difficult to figure out what a picture means, but a careful writer can almost always explain it.
段首句所表达的主题思想是一种看法，必须有具体事例加以验证。上述两个推展句只是在文字上对主题作些解释，整个段落内容空洞，简而不明。如果用一两个具体的例子的话，就可以把主题解释清楚了。比如下段：
It is not always true that a picture is worth a thousand words. Sometimes, pictures are pretty useless things. If you can’t swim and fall in the river and start gulping water, will you be better off to hold up a picture of yourself drowning, or start screaming "Help"?
3、连贯性（coherence）
连贯性包括意连和形连两个方面，前者指的是内在的逻辑性，后者指的是使用转换词语。当然这两者常常是不可分割的。只有形连而没有意连，句子之间就没有内在的有机的联系；反之，只有意连而没有形连，有时行文就不够流畅。
1）、意连
段落中句子的排列应遵循一定的次序，不能想到什么就写什么。如果在下笔之前没有构思，边写边想，写写停停，那就写不出一气呵成的好文章来。下面介绍几种常见的排列方式。
A．按时间先后排列（chronological arrangement）
B. 按位置远近排列（spatial arrangement）
C. 按逻辑关系排列（logical arrangement）
a. 按重要性顺序排列（arrangement in order of importance）
b.由一般到特殊排列（general-to-specific arrangement）
c. 由特殊到一般排列（specific-to-general arrangement）
2）、形连
行文的逻辑性常常要靠适当的转换词语及其他手段来实现。
4、有损连贯性的几种情况：
考生在写作中经常出现下面几种错误：
1、不必要的改变时态，
2、不必要的改变单复数，
3、不必要的改变人称
因此写作中，一定要注意时态，人称以及数的变化是否正确，要注意保持一致。
