    其它省略
    
    1、连词that的省略:
    
    ①、宾语从句中常省略连词that,但也有不能省略的情况(参看“名词性从句”等有关部分)。
    
    ②、在定语从句中,that在从句中作宾语时可省略。
    
    ③、引导主语从句、同位语从句等的连词that一般不可省略。在表语从句中偶尔可省略。
    
    2、不定式符号to的省略
    
    ①、并列的不定式可省去后面的to。
    
    I told him to sit down and wait for a moment.
    
    ②、某些使役动词(如let, make, have)及感官动词(如see, watch, notice, hear, feel, look at和listen to等)后面作宾语补足的不定式一定要省去to,但在被动语态中须把to复原。
    
    ---- I saw the boy fall from the tree.            ---- The boy was seen to fall from the tree.
    
    ③、介词but前若有动词do,后面的不定式不带to。
    
    The boy did nothing but play.
    
    3、在某些状语从句中,从句的主语与主句主语一致时,可省去“主语 + be”部分。(参看“状语从句”有关部分)
    
    4、连词if在部分虚拟条件句中可省略,但后面的语序有变化(参见“倒装句”有关部分)
    
    5、主句与从句各有一些成分省略。
    
    The sooner (you do it), the better (it will be).
    
    (二)[基础过关]
    
    1.  Some of you may have finished unit one. _____ , you can go on to unit two.
    
    A. If you may     B. If you do      C. If not            D. If so
    
    答案:D
    
    解析:省略句的用法。 If so = If you have done that / so
    
    2.— Shall Mary come to the concert with us?
    
    -Not ___she has finished her paper.
    
    A.since          B.once               C.when            D.unless
    
    答案:D
    
    解析:由题意可以得知,回答中用到了虚拟语气,是与过去的事实相反,补全句子应该是he would have given me one if I had wanted one.
    
    (三)[能力提高]
    
    1. Every evening after dinner, if not_____ from work, I will spend some time walking my dog.
    
    A. being tired  B. tiring         C. tired          D. to be tired
    
    答案:C
    
    解析:省略句式。在if引导的条件状语从句中,从句中还原应为if am not tired from work,根据省略的原则,所以答案选C。
    
    2. The government managed to have two chemical factories built, though _____ by the citizens.
    
    A. being opposed to B.opposed to        C.was opposed to   D.having been opposed to
    
    答案:B
    
    解析:由句意可以得知文中,补全句子应该是though (it was) opposed by the citizens,省略掉了it is
    
    3.______, Mr. Smith managed to send his daughter to school.
    
    A.As he was a poor man               B.A poor man as he was
    
    C.Poor man as was he                D.Poor man as he was
    
    答案:D
    
    解析:在as引导的让步再从句倒装对,名词前冠词应省略。提示:as引导的让步状语从句通常将表语或修饰谓语动词的副词提前至句首。
    
    6.——Where did you come across our chemistry teacher ?
    
    ------ It was in the supermarket ______ I purchased moon cakes.
    
    A. that                B. which             C. where          D. when
    
    答案:C
    
    解析:本题考查强调句的省略用法,被强调部分是一个定语从句,在moon cakes后省略了that I came across our chemistry teacher.
