解放军文职招聘考试太空引力

 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.

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. prove the theory 　　　　　　　　

D. disprove 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

(1—3 CCA)
