　　英語(yǔ)四級(jí)閱讀專練答案

　　1.[B] 事實(shí)細(xì)節(jié)題。本題主要考査復(fù)合句的理解。第2段最后一句表明B是正確選項(xiàng)。選項(xiàng)A中的most和C中的only都太絕對(duì)了，文中并未對(duì)選項(xiàng)A和C中的相關(guān)說(shuō)法加以這樣的限定。選項(xiàng)D也太絕對(duì)了，第2段第3句只是說(shuō)到“大多數(shù)情況下是因?yàn)榭照{(diào)設(shè)計(jì)欠佳所致”,并不是說(shuō)所有設(shè)計(jì)良好的大廈就不會(huì)發(fā)生這種情況。

　　2.[A] 事實(shí)細(xì)節(jié)題。本題考查復(fù)合句的理解。只要明白第3段第2句這個(gè)非限制性定語(yǔ)從句中的the bottoms ofwhich中的which是指上文的reservoirs,問(wèn)題就不難解決了。

　　3.[C] 事實(shí)細(xì)節(jié)題。本題考查被動(dòng)語(yǔ)態(tài)長(zhǎng)句的理解。在第3段第3句中，關(guān)鍵詞是highlight,選項(xiàng)C是對(duì)原句主謂部分的近義替換。選項(xiàng)A和B在文中皆無(wú)提及，選項(xiàng)D是過(guò)度使用生物殺滅劑的后果，與本題干的情況無(wú)關(guān)。

　　4.[A] 觀點(diǎn)態(tài)度題。第3段最后兩句討論生物殺滅劑的用處，其中最后一句中的but, dangerous和cancers等詞說(shuō)明作者認(rèn)為要慎用這種殺滅劑。作者并沒(méi)對(duì)殺滅劑全盤(pán)否定，只是說(shuō)過(guò)量使用會(huì)引發(fā)危險(xiǎn)，因此選項(xiàng)D不對(duì)。

　　5.[C] 推理判斷題。本題考查代詞的理解。解題的關(guān)鍵在于理解最后一句中的This是指上一句所說(shuō)的情況。選項(xiàng)A中所說(shuō)的人造環(huán)境不是使免疫系統(tǒng)變?nèi)醯谋厝粭l件。選項(xiàng)B是保持免疫系統(tǒng)健康的條件。選項(xiàng)D是免疫系統(tǒng)變?nèi)鹾蟮挠绊憽?/p>
