【题目】Experiments aboard the spaceship Columbia have disproved a theory on the human nervous system which won an Austrian professor a Nobel prize 79 years ago.

West German astronaut Ulf Merbold disproved the theory during tests aboard the spaceship yesterday. His discovery is connected with the workings of the inner ear, the body’s balance mechanism(机制).

In l914 Professor Robert Barany won the Nobel prize for Physiology(生理学) and Medicine when he announced that temperature differences affected the inner ear and caused the eyes to blink(眨眼). His theory was accepted by scientists.

But Merbold carried out tests to find if the theory was correct and shocked himself and space officials when he proved it wrong.

According to Barany’s theory the eyes would blink when cold air was blown into one ear and hot air blown into the other.

But if this theory was correct such a movement would be impossible in zero gravity(重力).

Both Merbold’s eyes continually blinked when the test was carried out.

【1】Tests were carried out in outer space in order to _______.

A. find what causes the eyes to blink

B. shock the world

C. win the prize

D. prove the theory

【2】Barany’s theory declared to prove _______.

A. how our hearing mechanism works

B. why we constantly move our eyes

C. that eye movement is affected by temperature

D. how hearing reacts(反应)

【3】Barany’s theory was proved incorrect in space by the effects of _______.

A. having no weight B. having no air

C. the pull of gravity D. hot and cold air streams

【答案】

【1】D

【2】C

【3】A

【解析】

试题分析:本文属于新闻类阅读,介绍了天文学家Ulf Merbold通过实验证明Robert Barany关于人体机制的一个理论是错误的,并介绍了这个实验的有关信息。

【1】D 推理判断题。根据文章第一段Experiments aboard the spaceship Columbia have disproved a theory on the human nervous system which won an Austrian professor a Nobel prize 79 years ago可知在宇宙飞船上进行了一项实验来证明之前的一个科学理论是错误的。所以该检测的目的在于证明这个理论。故D正确。

【2】C 细节理解题。根据文章倒数第三段According to Barany’s theory the eyes would blink when cold air was blown into one ear and hot air blown into the other.在这个实验中,当冷热空气被吹进耳朵的时候,人会眨眼。可知Barany认为眨眼是因为温度的变化。故C正确。

【3】A 推理判断题。根据倒数第二段But if this theory was correct such a movement would be impossible in zero gravity(重力).可知如果Barany的理论正确,那么在失重的情况下,人是不会眨眼的。最后一句Both Merbold’s eyes continually blinked when the test was carried out.告诉我们在这个实验中,在太空中,人仍然在眨眼。故A项正确。

【题目】What is the nature of the scientific attitude, the attitude of the man or woman who studies and applies physics, biology, chemistry, geology, engineering, medicine or any other science?

We all know that science plays an important role in our societies. However, many people believe that our progress depends on two different aspects of science. The first aspect is the application of the machines, products and systems of knowledge that scientists and technologists develop. The second is the application of the special methods of thought and action that scientists use in their work.

What are these special methods of thinking and acting? First of all, it seems that a successful scientist is curious - he wants to find out how and why the universe works. He usually pays attention to problems which he notices have no satisfying explanation, and looks for relationships even if the data available seem to be unconnected. Moreover, he thinks he can improve the existing conditions and enjoys trying to solve the problems which this involves.

He is a good observer, accurate, patient and objective and uses the facts he observes to the fullest. For example, trained observers obtain a very large amount of information about a star mainly from the accurate analysis of the simple lines that appear in a spectrum(光谱).

He does not accept statements which are not based on the most complete evidence available. He rejects authority as the only basis for truth. Scientists always check statements and make experiments carefully and objectively.

Furthermore, he does not accept his own idea, since he knows that man is the least reliable of scientific instruments and that a number of factors tend to disturb objective investigation.

Lastly, he is full of imagination since he often has to look for relationships in data which are not only complex but also frequently incomplete. Furthermore, he needs imagination if he wants to guess how processes work and how events take place.

These seem to be some of the ways in which a successful scientist or technologist thinks and acts.

【1】Which of the following statements about a curious scientist is TRUE?

A. He doesn’t find confidence and pleasure in work.

B. He is interested in problems that are explained.

C. He makes efforts to investigate potential connections.

D. He looks for new ways of acting.

【2】According to the passage, a successful scientist would NOT______.

A. easily believe in unchecked statements.

B. easily criticize others' research work.

C. always use his imagination in work.

D. always use evidence from observation.

【3】Which word can be used to describe the data that a good scientist uses?

A. complete B. concrete

C. complicated D. confusing

【4】 What does the passage mainly discuss?

A. Application of technology.

B. Progress in modern society.

C. Successful scientists' ways of thinking and acting.

D. How to become a successful scientist.

【题目】When I was having a walk through the park today, I met a friend I hadn’t seen for ages. She stared at me curiously. “You have kept this umbrella for years; it's old and out of date. I wonder why you keep it and take it wherever you go.” I smiled, “it means a great deal to me.” I simply gave her my shortest answer. Honestly speaking, I, either, could not understand the reason why I kept it.

Then all of a sudden, fallen leaves darkened my eyes with a strong wind. I grabbed the umbrella instinctively. The rain poured down. Thanks to my umbrella, I didn’t get wet at all.

“Why have I kept it for so long?” I asked myself, staring at my umbrella. I couldn’t remember when and where I bought it, for I’m always tired and lazy to answer questions. It could protect me from the heavy rain, I told myself eventually. Looking at the people rushing through the street, I felt safe. This might be another reason.

It is always so. We know a thunderstorm comes unexpectedly and goes without a warning. The sky cleared up. The sun shone brightly. Just as usual, I seized the umbrella with my left hand. Still there’s water dropping down. I walked among the noisy crowd and listened to what they were murmuring in their heart. “Today I will ask for a rise, or I'll leave this company.” Good luck to you, I smiled to him. “I’ll manage to make you live forever.” A little boy held a pet dog close to him. “She’ll be all right, because she is blessed.” I heard angels singing in this city.

The moment my fingertips touched the umbrella, I felt it’s dry, and it’s warm. Soon it became hot. I held it up to avoid harmful sunshine. Do I need a reason to explain why? Maybe I should think about it. I need my umbrella when it is sunny as well as when it is rainy.

【1】Which of the following words best describes the author?

A. Watchful. B. Hard-working.

C. Clever D. Strange

【2】 From the author's feelings with people among the noisy crowd, we can see that _____.

A. he is sensible enough to understand others’ murmur

B. he is sorry for people who can’t foresee their difficulties

C. he is warm-hearted even to care for unfamiliar people

D. he is kind enough to hope everyone will plan their life well

【3】What’s the most suitable title for the passage?

A. Try to notice every passer-by.

B. Umbrellas are important.

C. Always be prepared.

D. Weather changes unexpectedly.

【题目】阅读填空

I used to be the messiest person alive. Over the years, through watching others and by trial and error, I have finally found ways to come up with plans, organize them and follow through with them.

Make an outline of everything you need to have and do to make your plan happen. Make a list of all of the steps that need to be accomplished and think about what needs to be done.

Detail everything thoroughly and read over it so you can start coming up with some mental solutions of how to carry out your plans.

You should ensure that if for some reason way one doesn't work, you have way two and way three to lean back on. Therefore, different ways are needed at hand. It's just a matter of being organized. Chances are that there is always more than one way of doing things, and chances are that if one of those waysdoesn't work,one of the others will.

Committing yourself to finishing at least part ifnot all of your plan at once is also necessary. It willshow that you not only have initiative to get thingsrolling, but that you are interested in the resultsobtained with making the move to get everythingdone.

If you make a commitment to finish before aspecific time, make sure that you carry that out, andbe sure to do everything in the way you said youwould, within the time-frame you set for yourself.

Don't try to tackle (处理) more things all at atime. All that does is delay your progress, distract youand make you lose your interest, motivation andenergy.

Carrying out an effective plan requires being as organized as possible. You will only achieve this bysticking to the order of the plan and not deviating ortrying to do more at a time.

Last but not the least, you should never abandon things mid-project. It will only annoy everyonearound you including yourself. Unfinished plans are awaste of time, energy and, in some cases,evenmoney.

So,don't be afraid of organization. The older weget,the more necessary it becomes to have the skills to follow through with confidence and to be able tocarry through plans in an organized and manageable way. It pays to be organized, after all.
