问题补充：

I wanted to park my car by the roadside, but a policeman came up and told me .

A. not to

B. not to do

C. not do it

D. do not to

答案：

(答案→)A. not to

B. not to do

C. not do it

D. do not to

解析：考查不定式的省略。不定式在省略的时候，通常只保留不定式的符号to，把后面的成分都去掉。但是当不定式是to be…或者to have done/been的时候要保留be和have。句意：我想把车停在路边上，但是一个警察走了过来告诉我不要这样做。故A正确。
