He likes driving his car.A. must B. can C. need D. may【解析】 come,go,leave,start等趨向動(dòng)詞的進(jìn)行時(shí)表示將來(lái)時(shí)，所以答語(yǔ)是對(duì)這一將來(lái)動(dòng)作作出的推斷。may not“可能不；不一定”，根據(jù)he likes driving his car可以看出John可能乘火車來(lái)，也可能自己開車來(lái)。may not正好符合這一語(yǔ)境。must n

8、 if I _ in love ,at the age of seven ,with the Melinda Cox Library in my hometown.A. wouldn't have fallen B. had not fallenC. should fall D. were to fall【解析】 根據(jù)句意和I would be doing可以判斷這是虛擬語(yǔ)氣。at the age of seven 是表示過(guò)去的時(shí)間狀語(yǔ)，if從句中的謂語(yǔ)要用had not fallen，表示對(duì)過(guò)去情況的假設(shè)。由于主句中的謂語(yǔ)表示對(duì)現(xiàn)在的虛擬，條件句中的謂語(yǔ)表示對(duì)過(guò)去情況的虛擬，增加了試

9、題的難題，但是，使用排除法可以容易地做出該題：should fall 和were to fall都可以用于條件句中表示對(duì)將來(lái)的虛擬；wouldn't have fallen不用于條件句中，所以都不能作為答案。譯文：如果我不在七歲時(shí)就迷戀上了我們家鄉(xiāng)的Melinda Cox圖書館，我真不能想象我今天會(huì)做什么。答案為B。 11.I hear you've got a set of valuable Australian coins. _ I have a look?

11、】 just now是表示過(guò)去的時(shí)間狀語(yǔ)。情態(tài)動(dòng)詞在表示過(guò)去發(fā)生的事時(shí)，必須用“情態(tài)動(dòng)詞+have+過(guò)去分詞的形式”。所以只能在選項(xiàng)B或C中確定答案。mustn't have eaten是一個(gè)錯(cuò)誤選項(xiàng)，因?yàn)椤癿ustn't+動(dòng)詞”表示“禁止”，不表示判斷或推測(cè)。譯文：噢，我覺(jué)得胃不舒服。我剛才不應(yīng)該吃那么多炸雞。答案為C。 13.I was really anxious about you .You_home without a word.A. mustn't leave B. shouldn't have leftC. couldn't have le

Bob had walked farther B. if Bob should walk fartherC. had Bob walked farther D. if Bob walked farther【解析】 因?yàn)橹骶涞闹^語(yǔ)動(dòng)詞用了would have happened，所以從句的謂語(yǔ)動(dòng)詞要用過(guò)去完成時(shí)。在虛擬語(yǔ)氣中，如果條件狀語(yǔ)從句中的if省略，該句要倒裝。譯文：如果鮑勃走得遠(yuǎn)一點(diǎn)，走到岸邊，會(huì)發(fā)生什么事呢?答案為C。 16.
