15.Manyweeks．

16.unlikeunlike解析：根據(jù)下文，以日本學(xué)生與美國(guó)和韓國(guó)的作對(duì)比，日本的學(xué)生不像韓國(guó)和美國(guó)的學(xué)生一樣。所以此處應(yīng)填“unlike”。

17.worseworse解析：“the+比較級(jí)，the+比較級(jí)”，意為“越…越…，”根據(jù)上下文，本句句意為“身邊的小玩意兒越多，事情似乎就會(huì)變得越糟糕。”所以此處應(yīng)填“worse”。

18.atat解析：某大學(xué)的教授，應(yīng)為“aprofessorat…university”，所以答案為介詞“at”。

19.productionproduction解析：從前一句話“Themanufacturersgobeyondonlytellingconsumersabouttheirproducts.”可以看出，一方面廣告要介紹自己的產(chǎn)品，而第二個(gè)目的就是賣掉自己的產(chǎn)品。所以這里作者想要表達(dá)的意思是“廣告要使得顧客有一種購(gòu)買的欲望去購(gòu)買自己的產(chǎn)品。”故答案為production。

20.accordingaccording解析：此句意為“…一項(xiàng)個(gè)性與社會(huì)心理學(xué)的六月雜志的研究?！憋@然，空處應(yīng)填“根據(jù)”。

21.especiallyespecially解析：“Around1980many．Japanese，______youngpeople…”，“1980年左右許多日本人，尤其是年輕人…”，所以此處應(yīng)填“especially”。

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

23.ofof解析：beofthesame…意為“是一樣…”，此句意為“…在正確的指導(dǎo)下，他們能繼續(xù)學(xué)習(xí)，繼續(xù)通過(guò)干許多一樣復(fù)雜的工作而獲得多樣性。”

24.tastetaste解析：本句意為“我們看得見(jiàn)它，聞得見(jiàn)它，…它，喝它，而且在它中間掙扎。”由常識(shí)可知，此空處只有一個(gè)“嘗”較合適。

25.fromfrom解析：“來(lái)自…的數(shù)據(jù)”，要用介詞“from”。所以此處應(yīng)填“from”。

26.A解析：第二段中指出“…whenbrainandbodyareactive”，大腦積極運(yùn)轉(zhuǎn)是眼珠快速轉(zhuǎn)動(dòng)的主要特征，且在第三、四段又再次說(shuō)明。選項(xiàng)B“被研究者很快的反應(yīng)速度”，選項(xiàng)C“復(fù)雜的記憶模式”和選項(xiàng)D“前一天事件的重現(xiàn)”都不是眼球快速運(yùn)動(dòng)的主要特征。故應(yīng)選A。

27.D解析：由短文第二段中的“…showedthatthosewithnormalbloodpressureunderwentnochangeatallwhenplacedonanextremelylow-saltdiet，…”可知。

28.DD解析：此處的前一段說(shuō)明的是一些特殊情況，例如“Thesameistrueofthecrippledorphysicallyhandicapped．”而后面的一段指出“Ofcourse，theoppositeisalsotrue．”也就是說(shuō)在空白的地方，作者依然在說(shuō)明這些不尋常的情況，故應(yīng)選D。

29.D解析：選項(xiàng)A意思不準(zhǔn)確，文中提到公立大學(xué)和私立大學(xué)的學(xué)費(fèi)問(wèn)題，但并沒(méi)有表明家長(zhǎng)的態(tài)度和傾向；選項(xiàng)B意思不對(duì)，文中對(duì)應(yīng)
