一.省略的定义：为了避免重复，将句子中的某些成分省去，这种语言现象叫做省略。
二.省略的意义：省略是避免重复，突出中心信息并使上下文紧密连接的一种语法手段。通常来说，只要不破坏结构或引起歧义，能省略的地方就应省略。省略之后，不仅句子结构显得紧凑，而且句子意思更加明确。
例如：-Can you finish your work today?你今天可以完成工作吗？
-I think so.我认为可以。
（冉老师有话说：在该句的答语中用so替代了整个宾语从句部分。原句为I think I can finish my homework。）
-I hope he will win.我希望他会赢。
-I hope so, too.我也希望如此。
（冉老师有话说：该句中的so也是替代了整个宾语从句部分，原句为I hope that he will win.）
-It will rain tomorrow.明天会下雨。
-I believe not./I don"t think so.我不那样认为。
（冉老师有话说：该句的答语中省略了整个宾语从句，原句为I believe it will rain tomorrow./I don"t think it will rain.）
三.省略句历年真题练习：
1. (福建市考题)The climate here is quite pleasant, the temperature rarely,___,reaching 30°in summer.
A. if not B.if ever C.if any D.if so
（冉老师有话说：本题考查省略句。根据句中的关键词quite pleasant“宜人”，rarely“极少”可知，空格处表达的意思是“如果曾经有if ever”。If ever相当于if it(the temperature)ever reached 30°in summer.所以答案为B)
2. (江西省考题)If___to look after luggage for someone else inform the police at once.
A. asked B.to ask C.asking D.having asked
(冉老师有话说：本题考查状语从句中某些成分的省略。主句为祈使句，省略了主语you，根据语境可知，条件状语从句中you与ask之间为被动关系。所以答案为A）
3. (福建省考题)Any one, once___positive for HQN9 flu virus, will receive free medial treatment from our government.
A. to be tested B.being tested C.tested D.to test
（冉老师有话说：本题考查状语从句中的省略。由题干中的关键信息once可知此处为时间状语从句的省略。根据状语从句中省略的条件“当主句和从句主语一致，并且从句的谓语动词包括be动词时，可将从句的主语和be动词一起省略”,逆推可将该从句还原为“once anyone is tested positive for H7N9 flu virus”,并且时间状语从句中要用一般现在时，所以是省略了“anyone is”，所以答案为C.)
4. (湖北省考题)You can only be sure of___you have at present;you cannot be sure of something___you might get in the future.
A. that;that B.what C.which;that D./;that
(冉老师有话说：of后面是what引导的宾语从句，意为“你目前所拥有的”；something后面为that引导的定语从句，that在从句中作宾语，可以省略。所以答案为B）
5. (浙江省考题)Eye doctors recommend that a child’s eye exam____at the age of six months old.
A. was B.be C.were D.is
（冉老师有话说：本题考查省略句。Recommend“建议”后接宾语从句时，从句用虚拟语气，谓语动词用should do形式，should可以省略所以答案为B）
6.(四川省考题)-What’s the matter with Della?
-Well,her parents wouldn’t allow her to go to the party,but she still____.
A. hopes to B.hope so C.hopes not D.hopes for
（冉老师有话说：本题考查省略句。hope后再次出现前面出现过的动词不定式短语to go to the party，为了避免重复，只用动词不定式符号to代替。所以答案为A）
7.(重庆省考题)-Are you a volunteer now?
-No, but I____.I worked for the city Sports Meeting last year.
A. used to B.used to be C.used to do D.was used to
（冉老师有话说：本题考查省略句。动词不定式作某些动词的宾语时，常省略to之后的部分，但要保留to。当省略的动词不定式内含有做助动词用的have或be时，则保留have或be。此处为I used to be a volunteer.的省略。所以答案为B）
8. (新课标考题)The driver wanted to park his car near the roadsides but was asked by the police____.
A. not to do B.not to C.not do D.do not
(冉老师有话说：本题考查动词不定式符号to后面的保留与省略及其否定形式。通过分析题干并结合句意可知，动词不定式符号to后面省略了“Park his car near the roadside”,全句补充完整是“The driver wanted to park his car near the roadside but was asked by the police not to park his car near the roadside.”在此种用法中可以只在句中保留不定式符号to，而把与前面重复的内容省略；动词不定式的否定形式是直接在不定式符号to的前面加上否定副词not/ never.所以答案为B)
