内容提要:语法精讲:省略句的三大命题热点

热点一:if省略的固定搭配
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
解析:选B 句意:这里的气候宜人,即使曾经发生过,在夏季气温达到30摄氏度的情况也很少出现。if not“如果不”;if ever“如果曾经有;如果曾经发生”;if any“如果有的话”;if so“如果是这样的话”。if ever相当于if it (the temperature) ever reached 30℃ in summer。
常见if构成的省略的固定搭配有:
if so如果这样的话
if not 如果不这样的话
if ever 如果曾经有过/做过的话
if any 如果有的话
if necessary/important 如果必要/重要的话
It sounds like something is wrong with the car’s engine.If so, we’d better take it to the garage immediately.(2011·江苏高考)
听起来好像汽车的发动机出了毛病,如果这样的话,我们最好马上把车送到修理厂。
热点二:状语从句的省略
1.If________ for the job, you’ll be informed soon.
A.to accept B.accept C.accepting D.accepted
解析:选D 句意:如果你被接受做这份工作,你很快就会接到通知。句中you与accept之间为被动关系,应用过去分词,所以答案为D。本题中if之后省略了主语和be动词,补充完整为:If you are accepted for the job, you’ll be informed soon。
2.There are some health problems that, when ________ in time, can become bigger ones later on.
A.not treated B.not being treated
C.not to be treated D.not having been treated
解析:选A 句意:有一些健康问题,如果不及时处理,过些时候会变成比较严重的问题。when not treated in time是when some health problems are not treated in time的省略。
在状语从句中,如果主从句主语一致或从句的主语是it,且从句中含有be动词,可以将从句的主语和be动词一起省略。
①If (you are) asked to look after luggage for someone else, inform the police at once.(2013·江西高考)
如果有人要求为他照看行李,请马上报警。
②He stood at the gate as if (he was) to say something.
他站在门口好像要说什么。
③All the photographs in this book, unless(they are) stated otherwise, date from the 1950s.(2012·陕西高考)
这本书里所有的照片,除非有说明的,否则,都要追溯到20世纪50年代。
热点三:不定式的省略
The driver wanted to park his car near the roadside but was asked by the police ________.
A.not to do B.not to C.not do D.do not
解析:选B 句意:那名司机想把车停靠在路边,但是警察不允许他这样做。为了避免重复,常常省略与前文相同的部分,只保留不定式符号to。补充完整后应为“was asked by the police not to park his car near the roadside”。
在动词不定式结构中,为了避免重复,常常省略不定式结构中的动词,只保留to。
①I asked him to see the film, but he didn’t want to.
②—Will you join the game?
—I’d be glad to.
[点津] 如果承前省略的不定式中含有系动词be或助动词have时,be和have不能省略。
①—Are you a doctor?
—No, but I used to be.
②—He hasn’t finished the work.
—But he ought to have.
