Question

看下两个不定式题?
1.He was made __________ too hard.
A.work B.working C.to work D.to be work
15.The chair looks rather hard,but in fact it is very comfortable to ______.
A.sit B.be sat C.be sat on D.sit on
具体分析下>

Answer 1

第一题选C
我们一般都知道make sb.do sth,这是不带to的不定式.
其实不然,这是是在主动语态中的.在被动语态中,to要还原,也就是说,不定式要带上to,即sb.be made to do sth.
PS:这不仅针对make 还有其他一系列的感官动词,在变成被动语态的时候都要加上to.所以这题选C
第二题选D
it's adj to do sth,这里用带to的不定式
所以排除ABC,所D.
至于为什么要加个on：因为sit是不及物动词,后面要跟一个介词才能和名词或者代词连用.那题目中的名词或者代词在哪?
其实就是前面的chair.
把这句话还原it's very comfortable to sit on the chair..
