综合练：
1．“What were you trying to prove to the police?” “_________I was last night.”
A. That B. When C. Where D. What
【分析】此题应选 C，其余三项均有可能误选，答句为省略句，其完整形式为 I was trying to prove to the police where I was last night. (where 引导的是一个宾语从句)。请看以下类似试题：
(1) “What made her so happy?” “_________ her son passed the college entrance examinations.”
A. That B. 不填 C. Since D. For
【分析】此题选A，为That her son passed the college entrance examinations made her so happy. 之省略。
(2) “What made you so upset?” “_________ my wallet.”
A. Lost B. Losing C. Having lost D. Being lost
【分析】此题选B，为 Losing my wallet made me so upset. 之省略。
(3) “What did she tell you?” “_________ she would be late”
A. That B. When C. Where D. Whether
【分析】此题选A，为 She told me that would be late. 之省略。
(4) “What did he ask you?” “_________ I would be late.”
A. That B. When C. Where D. Whether
【分析】此题选D，为 He asked me whether I would be late. 之省略。
2．If the weather is fine, we’ll go. If _________, _________.
A. not, not B. no, no C. not, no D. no, not
【分析】此题应选A。If not, not. 为 If the weather is NOT fine, we will NOT go. 全句意为“如果天气好, 我们就去；如果天气不好，我们就不去”。该句的特点是：后句与前句的用词和句式完全相同, 只是前句为肯定，后句为否定，为了简洁起见, 于是将后句与前句相同部分省略，只保留否定词 not。又如：
If it is cheap, I’ll buy it. If not, not. 如果这东西便宜，我就买；如果不便宜，我就不买。
If you study hard, you’ll succeed. If not, not. 你若努力，你就会成功；你若不努力，你就不会成功。
If you start at once, you’ll catch the train. If not, not. 你若马上动身，你就会赶上火车；你若不马上动身，你就赶不上火车了。
请再看以下例子(只保留否定词not)。如：
“Can you repair it yourself?” “I am afraid not.” “你自己会修吗?”“恐怕不行。”(=I am afraid I can't repair it myself.)
“Did you know anything about it?” “Not until you told me.” “这事你以前知道吗?”“你告诉我才知道。”(=I didn't know anything about it until you told me.)
“Will it rain today?” “I hope not.” “今天会下雨吗?”“希望不会。”(=I hope it will not rain today.)
3．“She’s not a dancing teacher, is she?” “_________.”
A. Yes, and she isn’t B. Yes, but she was
C. No, but she isn’t D. No, but she was
【分析】此题最佳答案为D，可视为 No, she isn’t. But she was a dancing teacher. 之省略，即其意为“她现在不是舞蹈教师，但她过去是”。此题也可以是 No, but she used to be.
4．“
A. had B. would C. was going to D. did
【分析】此题应选C，为 I was going to come 之省略，意为“我本来是打算来的”，这与其后 but I had an unexpected visitor 的语境刚好吻合。注意不能选 would，因为它没有“打算”之意。
5.In some western countries, the rich are becoming richer, and _________.
A. the poor the poor B. poor poor
C. the poor poorer D. poorer the poor
【分析】此题应选C。句子后半部分为…and the poor are becoming poorer 之省略。句意为“在有些西方国家，富人变得更富，而穷人则变得更穷”。句中的 the rich 指“富人”，the poor 指“穷人”。按英语习惯，若前后两句谓语动词相同，则后句通常可承前省略。又如：
He is a teacher and his wife a nurse. 他是老师，他妻子是护士。(...his wife a nurse=...his wife is a nurse)
John won the first race and Mick the second. 约翰赢了第一场比赛,米克赢了第二场比赛。(... and Mick the second = ...and Mick won the second race)
In the accident the son was wounded, but the mother killed. 在事故中，儿子受伤，母亲丧命。(...but the mother killed=...but the mother was killed)
有时若后句的主语和宾语等与前句相同，也可一起省去：
He did it and quite successfully too at the beginning. 他这样做了，而且一开始就很成功。(=He did it and he did it quite successfully too at the beginning.)
6.“Would you like to come for a walk with me?” “I’d prefer _________, thank you.”
A. not to B. to not C. not D. can’t
答案选A，I’d prefer not to 为 I’d prefer not to come for walk 之省略。注意，在该省略结构中，用以代表不定式的 to 不宜省去。请看类例：
(1) “Shall I give the dog a chocolate?” “It’s better _________.”
A. not to B. to not C. don’t D. can’t
答案选A，为It’s better not to give the dog a chocolate 之省略。注意，不定式的否定式要将not 置于不定式符号to 之前，而不是之后。
(2) I would mend your radio, but I don’t know _________.
A. how B. to C. how to D. to how
答案选C，为 but I don’t know how to mend it. 之省略。
(3) Why didn’t you come at eight? You were _________.
A. told B. told to C. telling to D. to tell
答案选B，为 You were told to come at eight. 之省略。
(4) We should like Jane to get a good degree, but we don’t really expect _________. A. to B. her to C. to her D. her
答案选B，为 but we don’t really expect her to get a good degree. 之省略。
