15.highlysubjectiveway

16.WhenWhen解析：這里的一句話其實與下一半“whenwearedown-to-earth…．”所起到的作用是一樣的，同時兩者也是并列的，when表達了“當(dāng)…”，所以這里填when。故答案為when。

17.amongamong解析：此句意為“后一種觀點得到了許多支持者，尤其…教育家?！憋@然，空處應(yīng)填“在…中”，介詞among即有此意。

18.drinkingdrinking解析：由本句句意“通過將污水和化學(xué)物質(zhì)倒入河流和湖泊，我們已經(jīng)污染了我們的…水?！憋@然，此空處應(yīng)為“飲用”。

19.whichwhich解析：由37題解析可知此空應(yīng)為一個引導(dǎo)定語從句的詞，即which，其后的定語修飾“several(typesofcontamination)”。

20.happinesshappiness解析：根據(jù)上下文，日本年輕人更看重追求個人的幸福。所以此處應(yīng)填“happiness”。

21.whichwhich解析：此空后的句子應(yīng)為定語從句，修飾“tokeneconomies”，故此空應(yīng)填一個可引導(dǎo)定語從句的詞，而且前面可加介詞in。

22.thatthat解析：此空之后的內(nèi)容為suggests的內(nèi)容，即此處應(yīng)填that，引導(dǎo)賓語從句。

23.thatthat解析：此空后的內(nèi)容為maintain的內(nèi)容，即此空后的句子為maintain的賓語，應(yīng)填一個可引導(dǎo)賓語從句的詞。

24.disposedispose解析：由前一句“但是這個問題因為我們的“一次性”技術(shù)而加劇了?！笨芍颂帒?yīng)為“丟掉，扔掉”之意，即disposeof。

25.thoughthough解析：本句話的意思是“盡管知道顧客們可能不知道自己為什么買了這些商品，但是賣家卻知道怎么去做?！惫蚀鸢笧閠hough。

26.A解析：從文章第二段倒數(shù)第一句話“…andmanysaytheyremainoptimisticabouttheeconomy'slong-termprospects…．”可以看出，人們對現(xiàn)在的經(jīng)濟形勢并不擔(dān)心，相反他們認(rèn)為從長遠的角度來看，這種情況還是比較好的。故應(yīng)選A。

27.C解析：選項A即心理學(xué)家已經(jīng)放棄，而生物學(xué)家正在展開研究工作。而文中第三句話說“Psychologistsviewthesubjecteitherasamatteroffrustrationorajoke．”即心理學(xué)家認(rèn)為這個研究不是一件沮喪的事，就是一個笑話，此句和選項A含義不一樣。選項B即大腦區(qū)別顯示出一個性別優(yōu)于另外一個性別。而文中第一段最后一句話說“Butbeingdifferent，theypointouthurriedly，isnotthesameasbeingbetterorworse．”即他們指出盡管有區(qū)別，但并不能說明誰優(yōu)誰劣，此句和選項B含義不一樣。選項D兩性大腦結(jié)構(gòu)的區(qū)別早已為人所知。而文中第三段第三句話說“Thisisthefirsttimethatastructuraldifferencehasbeenfoundbetweenthebrainsofwomenandmen…”即這是第一次人們發(fā)現(xiàn)了兩性大腦結(jié)構(gòu)的不同，此句和選項D含義不一樣。所以本題應(yīng)選C。

28.CC解析：由下一段第一句“Thebookbeginswith…”可知，只有C放于此空處才可以與下文銜接，意思連貫。

29.D解析：由短文第二段中的“…showedthatthosewit
