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

In your life, you may have many unforgettable events like wining a prize, going aboard ……1.

I was always dreaming of swimming like a fish! At that time, I was so jealous when I saw people swimming. 2.Later, one summer afternoon, I followed my school buddies to a river, accompanied by my brother. I remember how eagerly I kicked off my shoes and jumped into the cool water. Truthfully, I was not sure what to do but struggle in the water. Luckily, a young swimmer nearby happened to find me and soon I was pulled out. Being out of water, I felt I was transported to the wonder world. Realizing that I was safe and well, I burst into tears.

I stepped carefully into the swimming pool but when the water came up to my stomach, I lost my balance again and fell into the water. I found myself further away from my brother than I thought. The king of Terror was approaching! Desperately, I kept my eyes wide open and tried to seize my brother by the arm, once, twice, three times….I was shouting and waving my arms exhaustedly. At last, my brother was able to reach out his hand to touch me. I got saved again.

4. But motivated by the desire to swim, I made my third attempt.. I felt my legs paralyzed(瘫痪) on the bank when I faced the big swimming pool. Watching the happy swimmers in the water, I was inspired. Why not have a last try? I took a deep breath and confidently went forward. As I was going deeper into the water, I made great efforts to control my thoughts, so I could keep the balance. 5.I was able to swim! Yes, I was able to swim!

Many people watched the lift-off of the space shuttle Columbia on March 21, 1982. But none watched more closely than eighteen-year-old Ted, as Ted’s insects were on board the shuttle.

The Shuttle Student Involvement Program invited students to make a science experiment. The experiment would be done by astronauts on the space shuttle.

Ted had always been interested in space and flight. Insect flight especially interested him. Ted noticed that insects need gravity to take off and land. They need gravity to fly in a straight line. But in space, there is no gravity. Could insects fly in zero gravity? That is what Ted wanted to find out.

Ted made an experiment called “Insect in Flight Motion Study”. He entered his experiment and soon news came that it was a winner.

A large team of scientists and engineers helped Ted get his experiment ready to fly. There were many questions to be answered first. What kind of insects would Ted use in his experiment? The insects would have to be strong enough to live on the shuttle for nine days without much food. What kind of container would hold the insects? Would the insects die during the shuttle flight?

After months of hard work, the “insectronauts” were chosen. A group of moths, flies, and honeybees were put into a special box and put onto the space shuttle. When Columbia flew into space, it was carrying insect passengers.

On March 24, astronauts Gordon Fullerton and Jack Lousma took out the box that held the insects. They began filming the insects with a special video camera.

When the space shuttle landed Ted was able to watch the video film of insects. Just as he thought, most of the insects did have trouble flying in zero gravity. The flies did well. But the moths’ flight seemed “uncontrolled”. They would often just hang in the air. The bees had the most trouble. They couldn’t fly at all! The film showed bees spinning around in all directions. Others were just floating about in the box.

Ted learned the answer to his question about insects’ flight in zero gravity. But he also learned a lot more. He learned about the hard work needed in making a successful experiment.

1.What does the underlined sentence “it was a winner” mean?

A．Ted could fly in space.                    B．Ted won a prize.

C．Ted’s experiment was accepted.           D．Ted won in a race.

2.What did Ted want to find out?

A．Whether the insects could fly in space.

B．Whether the insects could fly in a straight line.

C．Whether the insects could land after flying for a while.

D．Whether the insects could take off after resting for a while.

3.Of the three kinds of insects sent into space, which one flew worst in zero gravity?

A．The flies.          B．The honeybees.     C．The insects.        D．The moths.

4.Who did the experiment?

A．Ted himself.

B．Ted’s friend.

C．A large team of scientists and engineers.

D．Two astronauts on the space shuttle.

5.How did Ted learn the answer to his question about insects’ flight in zero gravity?

A．By asking the scientists and engineers.

B．By studying a book written by the astronauts.

C．By going into space and watching the insects’ flight himself.

D．By watching the video film made by the astronauts.

If you fly non-stop across Canada from Newfoundland in the east to British Columbia in the west, you can arrive before you set out, that is, by the time shown on clocks in British Columbia. Canada is such a big country that people in British Columbia may be having their breakfast while those in Newfoundland are perhaps already beginning their lunch. So the country is divided into five time zones, each an hour behind in time from the west zones to the east. For example, when it is 12 noon Atlantic Time in Newfoundland and the Madritime Provinces, it is 11a.m. Eastern time in most of Quebec and Ontario. Winnipeg, Manitoba, lies in the middle of the Central Time Zone, here it is 10 a.m. In most of the Prairies and the eastern half the mountains it is 9 a.m. Mountain Time while the west coast region has Pacific Time and it is 8 a.m.

45. The underlined word “non-stop” in the first sentence may mean ____.

A. to stop everywhere                            B. no stopping in Canada

C. without stopping before the final stop            D. to stop in Newfoundland

46. Which of the following is not the name of a place in Canada?

A. British Columbia.     B. Newfoundland.    C. Quebec.             D. Atlantic Time.
