▼优质解答
答案和解析
43 选 B
这里是考察 have的用法,have sth done ,过去分词表被动,使某物某人做某事,have his tooth pulled ,拔牙.牙齿是被拔的 ,所以用过去分词.
当然也有句型have sth doing,现在分词表主动.
47.选 B
这是考察动词不定式做宾语.
A how to do next,how是副词,不能做do的宾语,正确的说法是how to do it next.
C where to go to,to 是介词,后面应该接宾语,where只能做状语,正确的是where to go
D what to do it,这里it已经重复了,what就是做do的宾语,所以不用it
