Japan has a new craze: the virtual pet” Tamagocchi. The new object of consumer desire is the latest in high-tech — an electronic bird creature, the size of an egg that has been sold everywhere and is now only available on the streets at more than 20 times its original (原来的)price of 11,980 yen or $16.
You can feed it, stroke (抚摸) it, carry it in your pocket and even take it to the bathroom—all with a push of a button. But be aware of that if you don’t take care of your Tamagocchi—Japanese word for “lovely egg”— your pet will die before your eyes and before its time.
The Tamagocchi starts life as a bird-like image on the screen of an egg-shaped key-ring device. It changes from a chick to a fully grown alt in around 10 days. However, the owner must feed, clean and calm the digital(数字的) creature by pushing the proper buttons to prevent it from dying from neglect(忽视). The owner may choose to feed the creature digital sweets and enjoy its sound of delight by pressing buttons in response to the creature’s movements.

A. It can grow up in around 10 days.
B. It has to be fed, cleaned and calmed in case it might die.
C. It can proce a sound of delight.
D. It can be bought everywhere now.
44. What is the best title for the passage?

Some scientists say that animals in the ocean are increasingly threatened(威胁)by noise pollution caused by human beings..
The noise that affects（影响） sea creatures comes from a number of human activities. It is caused mainly by instrial underwater explosions（爆炸）, ocean drilling, and ship engines. Such noises are added to natural sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.
Decibels (分贝 measured in water are different those measure on land. A noise of one hundred and twenty decibels on land causes pain to human ears. In water, a decibels level of one hundred and ninety-five would have the same effect.
Some scientists have proposed（提议）setting a noise limit of one hundred and twenty decibels in oceans. They have observed that noises at that level can frighten and confuse whales（鲸鱼）.
A team of American and Canadian scientists discovered that louder noises can seriously injure some animals. The research team found that powerful underwater explosion were causing whales in the area to lose their hearing. This seriously affected the whales’ ability to exchange information and find their way. Some of the whales even died. The explosion had caused their ears to bleed（流血）and become infected（感染）.
Many researchers whose work depends on ocean sounds object to(反对) to a limit of one hundred and twenty decibels. They say such a limit would mean an end to important instrial and scientific research.
Scientists do not know how much and what kind of noises are harmful to ocean animals. However, many scientists suspect(认为，怀疑) that noise is a greater danger than they believed. They want to prevent noises from harming creatures in the ocean.
52.According to the passage , which of the following is increasingly dangerous to sea creatures?
A. The man-made noises.
B. The noises made by themselves.
C. The sound of earthquakes.
D. The sound of the ice- breaking.
53. Which of the following is discussed in the third paragraph?
A. Different places with different types of noises.
B. The very human ears sensitive to all types of noises.
C. The same noise measured differently on land and in the ocean.
D. The animal’s reaction(反应) to noises.
54. As to the influence (影响)of noises on whales, which of the following statements is true?
A. They are deaf to noises.
B. Noises at a certain level may hurt them.
C. They are easily confused by noises.
D. Noises will limit their ability to reproce.
55. According to the passage, what will scientists most probably do in the future?
A. They will try their best to decrease(减小)noise.
B. They will work hard to cut down noise pollution.
C. They will study the effect of different noises.
D. They will protect animals from harmful noises.

㈣ 科技英语阅读7内容太长了 到8里接着看吧
【1节】有两个主要的事情，使飞机工程困难;必须尽一切组成部分可靠的，可能和需要建立的一切轻如可能。事实上，飞机是在空中，不能停止，如果任何事情都会发生错误，这使得或许是生死存亡，其性能绝对可靠。鉴于某些权力的发动机，因此，一定燃料消耗，有一个实际的限制，总重量的飞机可以飞。在体重尽可能通缉燃料，无线电导航仪器，乘客座位，或货物的房间，当然，乘客或货物本身。因此，结构的飞机将作为体积小，重量轻的安全性和效率将允许。设计者必须计算出的正常负荷，每个部分将难以承受。这个专家称为''强调人' 。他考虑到任何不寻常的强调，可能是把一部分作为一个防范错误的制造，意外损坏等。男子应力的计算去设计的一部分，他必须一样强烈的应力男子说，如果必要的。一个或两个样品的测试总是证明他们是强烈的设计意图。每个单独的部分进行测试，然后整个装配，例如，一个完整的机翼，并最终整个飞机。当一种新型的飞机正在取得，通常只有一个头三个提出将飞行。两名将被摧毁在地面上的结构试验。第三是将测试空气中。【2节】两种地面强度试验进行。首先是寻找抗负荷的翅膀，尾巴等直至他们达到其最大负荷和崩溃。其他测试是疲劳强度。相对较小的载荷应用数千次。每个可以及在什么样的结构可以作为一个单一的负荷，但许多重复可能导致崩溃。一位从这个试验是这样做的客舱。这是充满空气在高压力，高超低空飞行，完全淹没在一个大罐的水，而测试正在进行中。周围的水无法从机舱爆裂像一个炸弹，如果有一个失败。当飞机已通过所有的测试可以得到政府的单机适航证，没有这一点，是非法的飞行，除了飞行试验。制作可靠的工作部件是困难的，因为决策的结构足够强大。飞行控制，电气设备，防火措施等。不仅必须重量轻，而且必须在高海拔地方的温度可能低于冰点和热空气的一个机场在热带地区。【翻译的还不错吧！】

㈥ 英语阅读理解文章
This is not the world we know. This world is controlled by computers. Men and women can be seen, but they are following orders given to them by machines. The machines were designed by mad scientists, but at some point even the mad scientists were taken over by their super-inventions.
Does this sound familiar? You have probably read something like it in magazines or books, or seen it in a film. Why is it popular? One of the reasons is that it reflects the fears of many people; fear of the unknown, fear of what is not understood or, at least, fear of something that is not completely understood.
The fact is that every day it seems that computers take control of another area of our lives. Some factory jobs are now done by robots(机器人)and the robots are controlled by computers. Our bank accounts are managed by computers. At the airport, our tickets are sold by a computer. Certainly many of these operations are made more efficient by computers, but our admiration is sometimes mixed with unsafe feelings. And this lack of safety is caused by the fact that we do not know how computers do these things, and we really don’t know what they might do next.
But we can find out how computers work, and once we understand them, we can use computers instead of worrying about being used by them. Today, there is a new generation of computer wizards(奇才) who know exactly how computers get things done. These young men and women, usually university students, are happy to sit for hours, sometimes for days, designing programs, not eating, not sleeping,. But discovering what can be done by these wonderful slaves which they have learned to control. These computer wizards have learned to use the computer and search for new tasks for their machine.
