13.You know that squeak(吱吱聲) you hear from your pet mouse or the pest mouse?It turns out that it is not really a squeak,but a sweet song by male mice to attract females.This is the conclusion reached by biologist Dustin Penn and his team at the Veterinary University of Vienna.
The scientists who have been conducting a series of studies on house mice for a number of years,began by recording the high-pitched(聲調(diào)高的) sounds male mice made the moment they sensed a female mouse around.What they discovered when they played them back to females was that the ladies could tell between those made by their brothers and the ones made by unrelated males.Just like human,they tended to ignore the ones made by their brothers.
The researchers then took the experiment one step further and analyzed the squeaks.To their surprise they discovered that while the squeaks sounded similar,they each had a different"tune".The biggest surprise of all was that the mice could even learn tunes from each other.
However,not all scientists agree with this finding.Some like Kurt Hammer,a scientist at the German Primate Center believe that the test sample was too small to make such a conclusion.
The researcher's next plan to test if the females care about the quality of the"song".In some bird species,males that can sing the most complex tunes seem to get the most attention.
So why do we care whether mice can sing or not?Clearly,since they are being used as laboratory testers,it will help us make advances in human speech disorders like the ones found in people suffering from autism(自閉癥).

分析 本文屬于說明文閱讀,作者通過這篇文章主要向我們描述了一項關(guān)于動物的聲音中包含的語言的研究,這項研究可以用來幫助人們治療人類的語言紊亂的問題.
解答 29.D.細節(jié)理解題.根據(jù)第一段中的but a sweet song sung by male mice to attract females 可知,雄鼠發(fā)出的是愉悅的聲音;故選D.
30.C.詞義猜測題. 根據(jù)第二段中的 recording the high-pitched sounds male mice made 可以推知,該詞指代上文提到的雄鼠發(fā)出的聲音;故選C.
31.A.細節(jié)理解題.根據(jù)第四段中的 the test sample was too small to make such a conclusion 可知,Kurt hammer 認(rèn)為得出這個結(jié)論的依據(jù)并不充分,人們需要進行更多的研究;故選A.
32.C.推理判斷題.根據(jù)最后一段中的since they are being used as laboratory testers,it will help us make advances in human speech disorders like the ones found in people suffering from autism可以推知,這項研究可以用來幫助人們治療人類的語言紊亂的問題;故選C.
點評 考察學(xué)生的細節(jié)理解和推理判斷能力,做細節(jié)理解題時一定要找到文章中的原句,和題干進行比較,再做出正確的選擇.在做推理判斷題不要以個人的主觀想象代替文章的事實,要根據(jù)文章事實進行合乎邏輯的推理判斷.
