Question

For some people, the sight of a mouse can be reason to scream. For other mice, the same sight can be reason to sing.

    Mice will probably   21   sing their way to any concert, but researchers in the United States have found   22   that mice do,   23  , sing.

    Scientists already knew that mice make ultrasonic(超聲波) sounds—noises that are too high-pitched(高音的) for people to hear   24   special equipment.

    To find out whether mice put such sounds together in song-like   25  , the researchers recorded the sounds of 1 mice. Using computer   26  , they were able to separate the sounds into specific types of syllables(音節(jié)), and found the mice produced about 10 syllables per second.

    The results showed that nearly all of the mice repeated sequences(順序) of syllables in different patterns. That’s enough to meet the definition of what scientists   27   song. But not all scientists are   28  _ that what the mice are doing is   29   singing. To prove it, the researchers must show that there’s learning involved. And, they need to __  30   why the mice sing.

21. A. almost                      B. even                        C. never                      D. usually

22. A. coincidence   B. evidence               C. guidance               D. instance

23. A. at once           B. by means              C. for example D. in fact

24. A. during                       B. inside                      C. through                 D. without

25. A. fashions                   B. instructions C. patterns                D. styles

26. A. access                      B. printer          C. screen          D. software

27. A. call                             B. hear                        C. sing                         D. write

28. A. accustomed  B. convinced             C. involved                 D. qualified

29. A. actually           B. obviously               C. simply           D. unlikely

30. A. figure out                B. get about              C. run across            D. talk over

解析:

導讀：這是一篇科普文章，文章講到科學家對于老鼠進行研究，從中發(fā)現(xiàn)他們也有自己的音律表達。

21. C�？疾楦痹~詞意辨析和語境的理解。從語篇知道老鼠開音樂會那是從來沒有的。

22. B。考查名詞詞意辨析和語境的理解。由上下文知道在美國的研究者找到老鼠唱歌的證據(jù)。

23. D�？疾榻樵~短語辨析和語境的理解。這里是說發(fā)現(xiàn)老鼠事實上也會唱歌。

24. D�？疾榻樵~詞意辨析和語境的理解。表示沒有特殊的設備人類聽不到老鼠所發(fā)出的音律。

25. C�？疾槊�詞詞意辨析和語境的理解。研究者在研究是否老鼠能夠把聲音結(jié)合在一起構成像歌曲一樣具有節(jié)奏。

26. D。考查名詞詞意辨析和語境的理解。運用電腦軟件來尋找節(jié)奏。

27. A。考查動詞詞意辨析和語境的理解。研究者發(fā)現(xiàn)它們的聲音可以組成有節(jié)奏的東西，這些證據(jù)可以符合歌曲的定義。

28. B�？疾閯釉~詞意辨析和語境的理解。表示并非所有的科學家都相信老鼠會唱歌。

29. A。考查副詞詞意辨析和語境的理解。表示“事實上”，即有寫科學家不相信老鼠真的會唱歌。

30. A�？疾閯釉~詞組辨析和語境的理解。figure out計算出, 解決；get about走動, 旅行, 傳開；run across偶遇, 跑著穿過；talk over詳盡地商議, 商量, 討論, 說服。下一步科學家們要解決的問題是為什么老鼠要唱歌。
