15.C

16.callscalls解析：此句意為“他把這種缺乏禮節(jié)的行為稱作是一種無意識(shí)的無禮”。call+雙賓語(yǔ)結(jié)構(gòu)，以為“把…稱為”，所以此處填“calls”。

17.airair解析：由前面的smog可知，此空處應(yīng)填與smog相應(yīng)的物質(zhì)，又由后面的“hoversovercities”可知，此物質(zhì)只能是“臟空氣”。

18.andand解析：這三個(gè)分詞短語(yǔ)是并列的，故中間的連詞只能用and。

19.onon解析：focuson意為“集中于”，為固定短語(yǔ)。

20.especiallyespecially解析：“Around1980manyJapanese，——youngpeople…”，“1980年左右許多日本人，尤其是年輕人…”，所以此處應(yīng)填“especially”。

21.whichwhich解析：由此句句子成分分析，此空以后的應(yīng)為定語(yǔ)從句，修飾characteristics，所以此空應(yīng)填which，引導(dǎo)定語(yǔ)從句。

22.nono解析：本句話的意思是“那些趾高氣揚(yáng)的人不可能是那些平易近人的人”。這是否定的意思，故答案為no。

23.gogo解析：gotoone'sheads的意思是“展現(xiàn)、表現(xiàn)”，俗語(yǔ)。用在文中表示“把…寫在臉上”，生怕別人不知道的顯擺。故答案為go。

24.SometimeSometime解析：通過對(duì)后面句子的分析，我們可以知道那些想入非非、飄飄欲仙的人有朝一日也是可以“雙腳落地的”，那就是“sharpwordsfromteacher”，所以這里表示的是“有朝一日”，故答案為sometime。

25.poorpoor解析：此句意為“但是很容易通過給…表現(xiàn)報(bào)酬或創(chuàng)造對(duì)報(bào)酬太…的期望而扼殺創(chuàng)造性?！憋@然，此空處應(yīng)填“劣拙的，不好的”。

26.C解析：由第三段最后一句“Lifeinsuranceisan…isnotsubjecttotaxes，incontrasttootherpersonalinvestments．”可知。

27.BB解析：由下一段第—句“Thepoker-lovingLouis-Dreyfusknew…”可知此空處填B最合適，因?yàn)椤癓ouis-Dreyfus，scionof…”必定在下一段之前邏輯上才講得通。

28.FF解析：第一個(gè)“myth”認(rèn)為隨著人口老齡化的增長(zhǎng)，西方國(guó)家的醫(yī)療體系會(huì)癱瘓。研究中的一位人口統(tǒng)計(jì)學(xué)家指出問題的關(guān)鍵是要建成靈活自由的醫(yī)療服務(wù)結(jié)構(gòu)。

29.EE解析：第一段引出了人們對(duì)未來的擔(dān)心，認(rèn)為老齡化將會(huì)帶來各種問題。第三段是對(duì)老齡化社會(huì)的肯定，認(rèn)為這是文明發(fā)展的成果。“myth”一詞含有杜撰的意思。一些人的擔(dān)心是多余的。E起到承上啟下的作用。

30.C解析：越來越多的人贊成Stiglitz的觀點(diǎn)，批評(píng)自由貿(mào)易和全球化，從“Suchclaimsarenolongercredible，forStiglitzispartofasmallbutgrowinggroupofeconomists，sociologistsandpoliticalscientists…”growing一詞可以看出答案。所以本題應(yīng)選C。

31.D解析：deforestat
