-Tom is never late for work.Why is he absent today?
-Something to him.
A.must happen B.should have happened
C.could have happened D.must have happened
答案 D
解析 本題考查情態(tài)動(dòng)詞的用法。must have done的意思是“一定發(fā)生了某事”。由對(duì)話所提供的情景可知:湯姆從不遲到,所以他“一定有事”。因此D項(xiàng)正確。

A.could B.would C.must D.need

of it as possible.
A.would B.could C.had to D.ought to
答案 B
解析 句意為:如果我能計(jì)劃做任何想做的事,我想去西藏盡可能地游覽一番。觀察一下句中的時(shí)態(tài),因?yàn)槎际沁^(guò)去時(shí),句意表示與現(xiàn)在事實(shí)相反的虛擬語(yǔ)氣,因此此處應(yīng)用情態(tài)動(dòng)詞的過(guò)去時(shí),表示的意思是“假如我們現(xiàn)在能夠……”,could表示不存在的可能性。

- You .You haven’t been in touch with him for ages.
A.will B.may C.have to D.should
答案 D
解析 本題考查情態(tài)動(dòng)詞的基本用法。will用于第二人稱常用來(lái)表示命令、指示,意為“務(wù)必,必須”;may表示“可能,也許”,常用于請(qǐng)求許可;have to表示“不得不”;should可用于表示主觀看法、建議、勸說(shuō),意為“應(yīng)當(dāng),應(yīng)該”。在此句中,答話者表示同意對(duì)方的想法。答語(yǔ)句意為:你應(yīng)該(打個(gè)電話),你好長(zhǎng)時(shí)間沒(méi)與他聯(lián)系了。故D項(xiàng)符合情景要求。
