Question

【題目】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(機制).

In l914 Professor Robert Barany won the Nobel prize for Physiology(生理學(xué)) 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(反應(yīng))

【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

Answer 1

【答案】

【1】D

【2】C

【3】A

【解析】

試題分析：本文屬于新聞類閱讀，介紹了天文學(xué)家Ulf Merbold通過實驗證明Robert Barany關(guān)于人體機制的一個理論是錯誤的，并介紹了這個實驗的有關(guān)信息。

【1】D 推理判斷題。根據(jù)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可知在宇宙飛船上進行了一項實驗來證明之前的一個科學(xué)理論是錯誤的。所以該檢測的目的在于證明這個理論。故D正確。

【2】C 細節(jié)理解題。根據(jù)文章倒數(shù)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.在這個實驗中，當(dāng)冷熱空氣被吹進耳朵的時候，人會眨眼�？芍�Barany認為眨眼是因為溫度的變化。故C正確。

【3】A 推理判斷題。根據(jù)倒數(shù)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的理論正確，那么在失重的情況下，人是不會眨眼的。最后一句Both Merbold’s eyes continually blinked when the test was carried out.告訴我們在這個實驗中，在太空中，人仍然在眨眼。故A項正確。
