十六套單項選擇
第一套
1.—He must be busy doing his homework right now.
—I imagine____.
A. that B. to C. so D. it
選C。I imagine so=I think so,
2. Mary had promised to give me a ticket for tomorrow. She failed, ____.
A. either B. though C. but D. too
選B。結(jié)合上下文意思我們可以知道本題表示轉(zhuǎn)折關(guān)系,先排除A、D;而but為并列連詞通常放在句首或句子中間起連接作用。故選B。
3. When I got to the cinema, the film _____ for five minutes.
A. had begun B. has been on
C. has begun D. had been on
選D。電影開始了五分鐘,for five minutes為一段時間要求謂語動詞要用延續(xù)性動詞,故A和C先排除,而從句的動作發(fā)生在主句動作之后。
4.---I wonder why Mr Green hasn’t showed up at the meeting yet.
