do not和have not有什么区别:
例如:If you hadn't pushed me,I wouldn't have fallen over.
(你如果不推我,我就不会摔倒的)
这里为什么不说:if you did not pushed me.
thank
比方说我要翻译一句话,形容某个东西没有充分插入,应该说have no insert fully,还是do not insert fully.
答
就你的例子来说吧,If you hadn't pushed me,I wouldn't have fallen over 一句是虚拟语气的固定用法,只能用过去完成时态hadn't pushed.你在学习中可能会碰到不少这样的句子.
