[A] These silent, zero-emission gadgets have long been used in NASA spacecraft. They represent the great hope of many environmentalists to power the first mass-produced electric car.´Àõ´AçÒ)öforum.liuxuehome.comÀ3G¬)ÜóX
Whether they are used to run cars and buses or to make electricity for other applications, fuel cells operate by converting hydrogen to electricity without combustion. They are akin to continuously-recharging batteries. Hydrogen and oxygen are fed into a stack of plates that create electricity, with harmless water vapor as the by-product.´Àõ´AçÒ)öforum.liuxuehome.comÀ3G¬)ÜóX
[C] While batteries alone haven’t supplied the performance most drivers want, proponents believe that fuel cells, probably combined with batteries, hold the promise of performance, range and better mileage compared with today’s internal combustion engines.´Àõ´AçÒ)öforum.liuxuehome.comÀ3G¬)ÜóX
[D] If they work, methanol fuel cells could be a major breakthrough in energy consumption and conservation. The brave new technology could drastically cut air pollution from auto emissions and other sources.´Àõ´AçÒ)öforum.liuxuehome.comÀ3G¬)ÜóX
[E] The size and weight of fuel cells have always been problems. New fuel-cell technology promises to solve those issues.´Àõ´AçÒ)öforum.liuxuehome.comÀ3G¬)ÜóX
[F] Fuel cells can use various sources of hydrogen, including a simple tank of compressed gas. But methanol, a liquid usually produced from natural gas, is a much more efficient way to store hydrogen. This is why the first wave of fuel cells in cars will likely use an indirect methanol fuel cell, in which the methanol passes through a mechanism called a “reformer”, which extracts the hydrogen.´Àõ´AçÒ)öforum.liuxuehome.comÀ3G¬)ÜóX
[G] A new, lightweight fuel cell that runs on methanol may one day power your electric car. Sooner still, the new cell may fuel smaller devices such as your lap-top computer or mobile phone.´Àõ´AçÒ)öforum.liuxuehome.comÀ3G¬)ÜóX

1) It is the business of the scientist to accumulate knowledge about the universe and all that is in it, and to find, if he is able, common factors which underlie and account for the facts that he knows. He chooses, when he can, the method of the “controlled experiment”. If he wants to find out the effect of light on growing plants, he takes many plants, as alike as possible. Some he stands in the sun, some in the shade, some in the dark, all the time keeping all other conditions (temperature, moisture, nourishment) the same. In this way, by keeping other conditions constant, and by varying the light only, the effect of light on the plants can be clearly seen. 2) This method of using “controls” can be applied to a variety of situations, and can be used to find the answers to questions as widely different as “Must moisture be present if iron is to rust?” and “Which variety of beans gives the greatest yield in one season? ”´Àõ´AçÒ)öforum.liuxuehome.comÀ3G¬)ÜóX
´Àõ´AçÒ)öforum.liuxuehome.comÀ3G¬)ÜóX
In the course of his inquiries the scientist may find what he thinks is one common explanation for an increasing number of facts. The explanation, if it seems consistently to fit the various facts, is called a hypothesis. If a hypothesis continues to stand the test of numerous experiments and remains unshaken, it becomes a law.´Àõ´AçÒ)öforum.liuxuehome.comÀ3G¬)ÜóX
´Àõ´AçÒ)öforum.liuxuehome.comÀ3G¬)ÜóX
3) The scientist is always most gratified to find that an underlying “explanation” of many phenomena suggests in its turn the possibility of proving its own accuracy or falsity by a suitably arranged critical experiment. He is also gratified when his “explanation”, if true, points to a new series of experiments designed to answer a new set of questions. For the curiosity of the scientist is never satisfied.´Àõ´AçÒ)öforum.liuxuehome.comÀ3G¬)ÜóX

The evidence as to the vastness of the universe and the complexity of its arrangements continues to grow at an amazing rate. The gap between what we know and all that can be known seems not to diminish, but rather to increase with every new discovery. Fresh unexplored regions are forever opening out.´Àõ´AçÒ)öforum.liuxuehome.comÀ3G¬)ÜóX
´Àõ´AçÒ)öforum.liuxuehome.comÀ3G¬)ÜóX
4) The rapidity of the increase of scientific knowledge, in the nineteenth and twentieth centuries, is apt to give students and teachers the impression that no sooner is a problem stated than the answer is forthcoming. A more detailed study of the history of science corrects the impression that fundamental discoveries are made with dramatic suddenness. Even in our present age no less than fifty years separate the discovery of radioactivity from the explosion of the first atomic bomb. Much of the fundamental information which now enables us to control the onset and duration of disease was known a century ago.´Àõ´AçÒ)öforum.liuxuehome.comÀ3G¬)ÜóX

5) The teacher, giving his brief accounts of scientific discovery, is liable to forget the long periods of misunderstanding, of false hypotheses and general uncertainty, which almost invariably precede the clear statement of scientific truth. (486 words)´Àõ´AçÒ)öforum.liuxuehome.comÀ3G¬)ÜóX

燃料电池能使用各种来源的氢气,包括一种简单的压缩气储罐。 但通常从天然气中产生的一种液体─—甲醇─—能跟有效地储存氢。这就是为什麽在小轿车中首批使用的很可能是一种间接的甲醇燃料电池。在该电池中, 甲醇里的氢通过一个叫做“重整器”的机械装置被提取出来。´Àõ´AçÒ)öforum.liuxuehome.comÀ3G¬)ÜóX
