參考答案及解析:
1.A
解析:A.as though引導(dǎo)的與過去相反的虛擬。
2. D
解析:D.felt是過去式,所以該句是由as though引導(dǎo)的與過去相反的虛擬。
3. D
解析:D.as if引導(dǎo)的與現(xiàn)在事實(shí)相反的虛擬。
4. 答案D.
根據(jù)題干可知,enjoy 是過去發(fā)生的動(dòng)作,而not see 這一動(dòng)作發(fā)生在enjoy 之前,即過去的過去。故用過去完成時(shí)。答案選D。
5.答案C.
本題考查現(xiàn)在完成時(shí)的基本用法。A強(qiáng)調(diào)現(xiàn)在習(xí)慣或經(jīng)常性的動(dòng)作,與過去無關(guān);B項(xiàng)表示現(xiàn)在或近段時(shí)期內(nèi)正在進(jìn)行的動(dòng)作,不能與for long 時(shí)間狀語連用;D項(xiàng)表示過去經(jīng)常發(fā)生的動(dòng)作,或者過去的動(dòng)作已經(jīng)結(jié)束,同樣不能和for long連用。C項(xiàng)強(qiáng)調(diào)發(fā)生在過去的動(dòng)作對(duì)現(xiàn)在造成的影響。答案選C。
6. 答案B.
根據(jù)第一個(gè)會(huì)話者所說的bought 的時(shí)態(tài),可知說的是過去的事情,用 “Did he?” 表示反問,讓對(duì)方進(jìn)一步證實(shí),故答案選B。
7. C
解析:(C)這是一人含蓄虛擬條件句,通過介詞短語without,表示潛在的一種假設(shè),而主句中的情況也早已經(jīng)發(fā)生,所以是對(duì)過去情況的一種假設(shè),因此用would not have been achieved這一形式。
8. D
解析:(D)連so that引導(dǎo)的從句中要求用虛擬語氣,表示一種假設(shè),形式為might+動(dòng)詞原形。
9. B
解析:(B)It is time that是一種要求從句用虛擬語氣的常見句型。虛擬語氣形式為動(dòng)詞的過去式。
10. 答案D.
動(dòng)詞need …+ v.-ing 結(jié)構(gòu)表被動(dòng)含義,類似用法的動(dòng)詞還有want, require, deserve, worth.. 另外,本句中wash 這個(gè)詞也通常主動(dòng)結(jié)構(gòu)表示被動(dòng)意思。如 read, write, clean, wash, iron, burn, draw, cook, keep, cut等。
