Question

Which sentence is WRONG？

1. A.
   We promise not to pollute the environment．
2. B.
   We promise never to pollute the environment．
3. C.
   We promise that we will never pollute the environment．
4. D.
   Our promise is that we have never polluted the environment．

Answer 1

D
分析：promise意思是“许诺”，许诺的事情应该是尚未发生的事情，A、B、C三项中分别用动词不定式的否定结构not to pollute，never to pollute和that宾语从句中否定谓语结构will never pollute来表示之后不发生的事情，但在D项的that从句中用现在完成时的否定结构明显是和promise的词义有矛盾。
