They were also constant communication with people on the earth.  22 , being with people from whom you cannot get away might be even harder than being alone. This is what happens on long submarine (潛水艇) voyages. It will also happen on  23  space flights in the future. Will there be special problem of adjustment under such conditions?

Scientists have studied the reactions of men to one another during long submarine voyages. They have found that the longer the voyage lasts, the more serious the problem of 24  is.

Apparently, although no one wants to be  27  all the time, everyone needs some degree of privacy. When people are enclosed together, they are in what is called a stress situation. That means that they are under an unusual amount of  28  or stress.

People who are well-adjusted are able to  29  stress situations better than others. That is one reason why so much care is taken in  30  our astronauts. These men undergo a long period of testing and training. One of the things tested is their behavior under stress.

完形填空解析

獨自一人在太空中飛行讓人感到孤獨、壓抑。科學家門研究發(fā)現，長時間乘坐潛水艇航行，需要對情緒作一些調整，否則就會處于一種長期的壓抑狀態(tài)中。在挑選飛行員時，要選那些心理素質好的，訓練時特別注意他們處于壓抑狀態(tài)中的反應。

21．答案：D    考點：形容詞詞義辨析

    解析：讓獨自進行太空飛行的宇航員有事情可做，使他們處于忙碌的狀態(tài)（不至于感到孤獨）。

22．答案：C    考點：連接性副詞詞語辨析

    解析：根據上下文的邏輯關系，此處表轉折關系，故選C項。so far迄今為止，表時間；therefore 表因果關系；after all 用來提醒對方注意。

23．答案：A     考點：形容詞詞義辨析

    解析：上文 “This is what happened on long…”已暗示，故選A項。

24．答案：C    考點：名詞詞義辨析

25．答案：A    考點：動詞短語詞義辨析

解析：根據句意：“在有限的空間中呆很長時間，既不說話，也不挪動會使人變得厭煩�！盇, C, D三項均不合乎題意。

27．答案：B    考點：形容詞詞義辨析

    解析：前后句為轉折關系，只有B項與后半句中privacy的意義相近。

28．答案：D

    考點：動詞詞義辨析

    解析：根據句意，空格內應填一個表“應對，處理”的詞，只有A項符合。create創(chuàng)造，帶來；affect影響；investigate調查。

30．答案：B       考點：動詞詞義辨析

    解析：根據上文，心理素質好的人比別人更能很好地應對壓抑（stress situations）。在挑選飛行員的時候要特別注意這一點。become成為；order預訂；promote促進，促使。
