高一英语 非谓语动词 选择题疑问

___ your composition carefully, you can at least avoid some spelling mistakes.
A.Check B. To check C. Having checked D. If you check
为什么不能选C。D表示什么？

什么时候才要用从句

从句可以与非谓语动词互换。
If you check your composition carefully, you can at least avoid some spelling mistakes.
=Checking your composition carefully, you can at least avoid some spelling mistakes.
=Check your composition carefully, and you can at least avoid some spelling mistakes.
Having checked 表示检查的动作在先，避免拼写的错误在后，语意错。应该的检查的时候就可以避免拼写错误，所以用 checking,不用having checked 。

这句话 的翻译是：如果你的作文写得更仔细的话，你至少能够避免一些拼写的错误 这里是条件状语从句， If 引导的，这里如果直接用C的话 句义不完整
