Question

英语句子解释,这句为什么没有介词来修饰时间词?
When the reply came a few months later they were enrolled as full members,but Chu's membership was kept a secret from outsides.词句中 a few months later 怎么没有用介词in 修饰?是否later 做副词(后来,随后)时修饰了 a few months

Answer 1

He left China two days ago.He left China two days before the president died.
He came back two days later.He came back to China two days after the earthquake.
一段时间后面要是有ago,before later after...等前面是不加介词,而且一般用过去时态.
当有in 的候,时态也不一样.
He will leave China in two weeks.
