1.-Do you often have someone ( )your clothes?-Yes,I often have them ( ).
A.wash ; to wash B.to wash; washed C.washed;wash D.wash ; washed
(为什么选D?)
2.She finished her letter,and read it through ( ).
A satisfaction B.with satisfaction C.satisfied D.satisfying
(为什么选B 为什么不选A?)
3.The problem _______ at tomorrow’s meeting is a very difficult one.
A、being discussed
B、discussed
C、to be discussed
D、to discuss
(我们学过:“不等式作定语或与被修饰词是主谓、动宾、同位等逻辑关系时,多用主动形式”,那为什么这道题选C ,而不选D呢?)
1.第一个空格是表示have somebody do sth.这个do的动作,是somebody 发出来的,所以是wash,而第二个的话,是have sth done的形式,不是sth自己会去做,而是被人做,所以是done;
2.里边出现两个词组哦,read through 是一起组成个动词词组,表示“读完,通读”,然后后边剩下的词,应该是个副词,或者副词词组,才能修饰动词,所以是with satisfaction(这个介词加名词组成的词组,表示“满意地”),当然,也可以用satisfiedly.
3.问题是“明天要被讨论”,首先,因为是明天,所以修饰的时候,我们用不定式来表示将来,同时,因为它自己不能发出讨论的动作,就变成 to be discussed 了.如果变成the problem which is to be discussed at tomorrow's meeting is a very difficult one.是不是更容易理解?:) 因为which指代的就是the problem,充当主语,而且谓语动词是is(属于be动词),所以,可以把which is给省略掉~
加油咯
