1.[B]。本題的測(cè)試點(diǎn)是狀語從句。由when引導(dǎo)的時(shí)間狀語從句通常是相對(duì)于另一個(gè)的動(dòng)作。當(dāng)表示另一個(gè)動(dòng)作先于when引導(dǎo)的時(shí)間狀語從句的動(dòng)作時(shí),主句中的謂語動(dòng)詞可用過去完成時(shí),從句中的謂語動(dòng)詞可用一般過去時(shí)。四個(gè)選項(xiàng)中as、while這兩個(gè)連詞引導(dǎo)的從句往往表示主句與從句的動(dòng)作幾乎不分前后,基本上是同時(shí)的。after引導(dǎo)的從句表示“在……之后”,與本題時(shí)態(tài)不符合。因此,B是正確答案。
句意:在我剛返身回家去換衣服時(shí)聽見了一陣說話聲。
2.[D]。本題的測(cè)試點(diǎn)是現(xiàn)在完成進(jìn)行時(shí)。該句中的時(shí)間狀語"for sometime"表示“……已有一段時(shí)間了”,與答案has been leaking相呼應(yīng)。這一時(shí)態(tài)由have(has)+been doing構(gòu)成。它表示動(dòng)作從過去某一時(shí)間開始,一直延續(xù)到現(xiàn)在,可能還要繼續(xù)下去,通常與表示一段時(shí)間的狀語連用。例如:They have been watching television for two hours(他們已經(jīng)看了兩小時(shí)的電視了).A、B、C三項(xiàng)與句中時(shí)態(tài)不符合。
句意:看起來這管子漏油已有一段時(shí)間了,我們必須把機(jī)器拆開修理一下。
3.[A]。本題的測(cè)試點(diǎn)是固定搭配。none but表示“只有,除……外誰也沒有”。例如:None but fools will believe it(除了傻瓜沒有人相信它).在這種用法中,but后面用主格人稱代詞很少見。在現(xiàn)代英語的非正式文體中,更常用的是人稱代詞賓格形式,如me,her等。例如:Who would do a thing like that? Nobody but her.none other than意為“不是別人(或他物)而正是”,如:It was none other than Mr. Wang(不是別人而正是王先生).nothing but意為“除了……以外什么也不,只有,只不過”,如:I've eaten nothing but bread and cheese since Sunday(自從星期日以來,除了面包和乳酪之外,我別的什么東西也沒吃).nothing but和none but意義相近,但用法略有不同:none but修飾人,nothing but多半修飾物。no other than表示“只有,正是”。
句意:當(dāng)他到家時(shí),發(fā)現(xiàn)只有老人和病人在家。
4.[A]。本題的測(cè)試點(diǎn)是非謂語動(dòng)詞。本題的pressure要求一個(gè)定語。to compete是不定式,表示“競(jìng)爭(zhēng)的(壓力)”,可作pressure的后置定語。competing是現(xiàn)在分詞,如作定語常置于名詞之前。如:Competing demands意為“互不相讓的要求”。to be competed為不定式被動(dòng)語態(tài),而compete常用主動(dòng)語態(tài)形式,如:compete in a race,compete with/against.having competed是現(xiàn)在分詞完成式,不符合本題句意。
句意:競(jìng)爭(zhēng)的壓力使得美國人精力旺盛,但同時(shí)也使他們長(zhǎng)期處于情緒緊張的狀態(tài)。
5.[C]。本題的測(cè)試點(diǎn)是動(dòng)詞慣用搭配。want與need較相似,在表示“需要、應(yīng)該”時(shí),要求跟動(dòng)名詞主動(dòng)語態(tài)或不定式被動(dòng)結(jié)構(gòu)。如:The house wants repairing/to be repaired(這房子需要修理了)。據(jù)此可知,只有C項(xiàng)是正確結(jié)構(gòu)。
句意:你該理發(fā)了,你最好明天就理。
