31 . D 。考點:將來完成時的用法。 by the time 常用于引導(dǎo)時間狀語從句,其主句一般要用完成時。因從句中謂語動詞為一般現(xiàn)在時,其主句的謂語要用將來完成時。句意:等他到達(dá)北京的時候,我們在這兒已經(jīng)呆了兩天了。
32 . C ?键c:名詞的辨析。 scope 范圍; rank 等級; span 一段時間; scale 比例。 life span 是固定搭配,意為“壽命(生命的全長)”。句意:根據(jù)美國聯(lián)邦政府的統(tǒng)計,夏威夷居民的壽命最長,為 77.2 歲。
33 . C ?键c:虛擬語氣在非真實條件句中的使用。 had they been done by hand 是一個省略了 if 的用倒裝語序的非真實條件句,表示與過去事實相反,所以主句也要用相應(yīng)的虛擬語氣形式“ would have+ 過去分詞”。應(yīng)該注意的是,該非真實條件句不像通常那樣位于主句前面,而是插在了主句中間。句意:所需的數(shù)百萬次的運算如果用手工來做,那到它們完成的時候,也就失去了所有的實用價值。
34 . D ?键c:不定式在復(fù)合謂語結(jié)構(gòu)中的用法。該結(jié)構(gòu)中不定式的動詞若是表示動作的動詞(如 do, take, learn 等)要用完成形式表示結(jié)果或狀態(tài),若是狀態(tài)動詞(如 be, like, have 等)則用一般式表示結(jié)果或狀態(tài)。因題中不定式動詞 know 是一個狀態(tài)動詞,故用一般式。句意:作為一個公共關(guān)系職員,據(jù)說他認(rèn)識一些很有影響的人物。
35 . D 。考點:動詞意義的辨析。選項中四個動詞意義分別是: aroused vt . 引起,喚起; arouse vi . 出現(xiàn),發(fā)生; raised vt . 舉起,養(yǎng)育; rose vi . 升起,上升。本句要求填入一不及物動詞,再根據(jù)意義分析, rose 正確。句意:我們的希望瞬間升起,但瞬間又破滅了。
