With time went by, I found that I could 9. _even communicate some college students freely. 10. _答案I. 1. B。run over 及物动词，意为“碾过” 。get 接过
20、去分词表示被动。句意是：否则你就会被汽车压着。2. C。 “need/ want/ require +doing 或 to be done”结构。3. B。主句中带了宾语，不用被动式。leave 这里作“离开” ，及物动词，后应接宾语。4. A。 ought to 的否定形式为 ought not to 或 oughtnt to， 因此，排除 B、D。而 C 表示对过去情况的一种假设，不符合题意。故选 A。5. A。cannot / can not / never too / enough 是一固定搭配，表示“ 越越好” 、 “再也不过分”II. 1. B。cant have done 表示对
21、过去发生的行为的不肯定推测，意为“不可能干过某事” 。2. D。因对话是对过去事情的推测，所以不能选择 A 和 B。从上句意义可知：已坐了 5 个人的小车里再挤一个人一定不是舒服的旅行。答案为 D。3. C。表示对未来可能出现的一种事实的推测，但不是很肯定。4. D。谚语：“三人行，必有我师” 。5. C。前句是 must have +过去分词时，若前句强调对过去情况的推测（一般都有过去时间状语） ，疑问部分的谓语动词用 didnt + 主语；若前句强调动作的完成，疑问部分的谓语动词用 havent/ hasnt +主语。根据题意，by the end of last month（到上月底为止
22、） ，表示动作的完成。6. C。cant have done 表示对过去发生的行为不肯定。7. D。考查情态动词的用法。can 表“可以” ，neednt 表“不必” 。8. D。句意： 她一定回到峡谷了。 不，不可能的。峡谷口找不到的。must have done 的否定形式应是：cant / couldnt have done。9. C。could have done 意为“本来可以干某事” 。10. D。should 用在表示遗憾的从句中。11. A。 can 不能用于肯定句中表示推测；will 表将来或意愿；should have done 意为“本应该却未” 。句子表达的是一种对过去
23、的猜测，但可能性不大。12. B。同上。13. B。该题是 2002 年上海高考题。考查与过去事实相反的假设情况，即虚拟语气再 if 条件句中的运用问题。句意：要是七岁那年不开始那么迷恋 Melinda Cox 图书馆的话，难以想象我今天能干些什么。由题意排除 C、D。由题干 at the age of seven 得知是对过去情况的一种假设，故从句时态用 had +过去分词，即选 B。14. C。因为题目中由 ought to， 其表示过去动作的 have 在省略回答时不能舍弃。15. D。在过去谁会料到这种严重的病也会治愈。由此可见选 D。因为 would have done 表示过去将会
24、做，符合题意。B 项容易引起歧义，它表示 “原以为” 。III.1B。根据上一句所谈的工作是邮差、信使得知。2A。根据下文讲述内容可知她讲述的应该是一个故事。3B。six months earlier “六个月以前” ，通常与完成时连用。4C。据上文谈到的他的工作是“ 邮差”可知应为“投递”信件。5D。信件上有她的街道号码。6C。据上下文意思可知，产生麻烦的根源是标有相同的号码。7B。drop sth. off 将某物送到某处。8D。sth. be intended for 某物本打算给某人。9B。据后面的他们 start dating (开始约会) 得知，Johnson 仍是单身 (sing
25、le)。10C。他们先是谈话，后来打电话，再后来开始约会，然后他们就一起外出。11A。解释同上。12B。由后半句的“把两个好人联系在了一起 ”作者是很高兴的。13D。据后面的 “soon the house was sold”得知，此处应为“待售”标志。14C。据后面的“the wedding happened”得知，此处应为“the wedding invitation ”(结婚请柬)。15B。根据句意判知，前后两句应为并列关系。16D。据下文内容可知，此处指的是 Johnson 夫妇的院子。17C。看到这对夫妇的房子在出售，于是作者唯恐他们的婚姻出现危机。 18C。make up an excuse 编了借口。19A。check on sb.检查某人看情况是否正常。20D。据前面的话可知，他们只好搬家(move)。IV. 1. 2. there where 3. surprised surprise 4. were was 5. me mine6.
