Once Wilhelm K. Roentgen and several other scientists were experimenting with passing electric currents through certain gases in a special glass tube （管子） from which the air had been taken away. Then one day Roentgen noticed that though the tube was covered with black paper， some strange kind of radiation were coming through and making a screen nearby give out light. Roentgen could see nothing out of the tube. But then he discovered that if he put the screen in the next room on the other side of the closed door， the rays still seemed to affect it. The screen showed that the rays could pass not only through the black paper but also through wood.

The next thing he found out was that if he put his hands between the rays and a photographic plate， the rays would print a shadow of the bone framework （骨架） of his hands on the plate. In fact， the rays could pass as easily through the fleshy （肉的） part of his hand as through the black paper， but hardly at all through the bone. So Roentgen made the first X-ray picture of a hand showing just how the bones in the hand fitted together.

Roentgen called these unknown rays X-rays， but other scientists called them Roentgen rays in honor of the man who first found them.

A. Air. B. Water.

C. Gases. D. Nothing.

A. by accident

A. Wood. B. Bones.

阅读表达（阅读下面短文，并按照题目要求用英语回答问题。）

Some expressions describe people who are important， or who at least think they are. One such expression is “bigwig”.

In the seventeenth century， important men in Europe began to wear false hair， called wigs. As years passed， wigs began to get bigger. The size of a mans wig depended on how important he was. The more important he was—or thought he was—the bigger the wig he wore.

Today， the expression “bigwig” is used to make fun of a person who feels important. People never tell someone he is a bigwig. They only use the expression behind his back.

“Big wheel” is another way to describe an important person. A big wheel may be the head of a company， a political leader， a famous movie star. They are big wheels because they are powerful. What they do affects many people. Big wheels give the orders. Other people carry them out. As in many machines， a big wheel makes the little wheels turn. “Big wheel” became a popular expression after World War II. It probably comes from an expression used for many years by people who fix parts of cars and trucks. They said a person rolled a big wheel if he was important and had influence.

The top of something is the highest part. So it is not surprising that top is part of another expression that describes an important person. The expression is “top banana”. A top banana is the leading person in a comedy show. The funniest comedian is called the top banana. The next is second banana. And so on. Why a banana？ A comedy act in earlier days often included a part where one of the comedians would hit the others over the head with a soft object. It was shaped like the yellow fruit： the banana. “Top banana” is still used mainly in show business. Yet nowadays the expression can also be used to describe the top person in any area.

1. Who began to wear wigs in the 17th century？ （within 4 words）

2. Why do we call political leader a big wheel？ （within 5 words）

3. When did “big wheel” become a popular expression？ （within 4 words）

4. Who could be called the top banana in a comedy show？ （within 3 words）

5. What is “top banana” used to describe nowadays？ （within 8 words）

Psychologist George Spilich and workmates at Washington College in Chestertown， Maryland， decided to find out whether， as many smokers say， smoking helps them to “think and concentrate”. Spilich put young non-smokers， active smokers and smokers deprived （被剥夺） of cigarettes through many tests.

In the first test， each subject sat before a computer screen and pressed a key as soon as he or she recognized a target letter among a group of 96 letters. In this simple test， active smokers， deprived smokers and non-smokers performed equally well.

The next test was more complex， requiring all to look quickly at orders of 20 same letters and respond to the immediate one of the letters transformed into a different one. Non-smokers were faster， but under the encouragement of nicotine， active smokers were faster than deprived smokers.

In the third test of short-term memory， non-smokers made the fewest errors， but deprived smokers committed fewer errors than active smokers.

The fourth test required people to read a passage， and then answer questions about it. Non-smokers remembered 19 percent more of the most important information than active smokers， and deprived smokers bested those who had smoked a cigarette just before testing. Active smokers were not only likely to have poorer memories but also had trouble picking important information from unimportant details （细节）.

“As our tests became more complex，” Spilich concludes， “non-smokers performed greatly better than smokers.” He predicts， “Smokers might perform well enough at many jobs—until they got complex. A smoking airline pilot could fly well enough if no problems appeared， but if something went wrong， smoking might damage his mental capacity （容量）.”

1. Whats the purpose of George Spilichs experiment？

A. To show how smoking damages peoples mental capacity.

B. To prove that smoking affects peoples regular performance.

C. To find out whether smoking helps peoples short-term memory.

D. To test whether smoking has a positive effect on the mental capacity of smokers.

2. George Spilichs experiment was conducted in such a way as to ___ .

A. check the effectiveness of nicotine on smokers

B. register the immediate responses of the subjects

C. put the subjects through increasingly complex tests

D. force the subjects to pick major information from less major details

3. The underlined word “bested” in Paragraph 5 most probably means “___”.

A. lost B. beat

C. hated D. caught

4. It can be inferred from the last paragraph that ___ .

A. no airline pilots smoke during flights

B. smoking in urgent cases causes mental illness

C. smokers should not expect to become airline pilots

D. smokers may prove unable to deal with urgent cases
