after后面跟to do还是doing

after后面跟to do还是doing

“after doing”。after为介词，根据介词后面如果要加动词，只能用动词的现在分词形式，所以after后面不能用do，只能用doing。例句：You may have a rest after doing your homework.做完作业后你可以休息一会儿。after doing还是do【为什么after后不能用do】“after doing”成立，但“after do”不成立。其关键点在于：after为介词，介词后面如果用动词，只能用动词的现在分词（动名词）形式，即doing作做宾语。【after doing 双语例句】意为“做某事之后”。例句 1. You may have a rest after doing your homework. 做完作业后你可以休息一会儿。例句 2. I don't know how she copes with looking after her family and doing a full-time job. 既要照顾家庭又要全天工作，我不知道她是如何对付的。例句 3. He improved his grade after doing well on the last exam. 自从上次考试表现不俗之后，他的成绩就开始提高了。例句 4. After doing her homework, there was not so much time left. 在她做完家庭作业之后，没有多少时间剩了。例句 5. It can be used directly or used after doing moistening procedure. 可直接使用，也可在润肤程序后使用。例句 6. After doing this, Local Lag is used to control the consistency of the system. 然后运用本地滞后技术进行基本的一致性控制。
