Question

The boy wanted to ride his bike in the street ,but his mother told him （）A.not to B.not to doC.no

-t do it D.do not to选哪个，为什么

Answer 1

B需要加宾语。
C不符合习惯用法。
A习惯用法，像这种前后宾语一致，为了不使整个句子表达罗嗦,往往后者要省略,(个句子省略的就是: not to ride his bicycle in the street.)但是,要注意,省略时有介词要带介词,没有的不用带.

Answer 2

C not to do it
tell sb. to do sth.
tell sb. not to do sth.
固定用法。
it代词，代指前文所提到的 ride his bike in the street。

Answer 3

选A
