是时候去购物了英语为什么是过去式呢

Question

如题所述

Answer 1

“是时候去做某事了”的句型结构：It is (high) time (that) sb. did sth.

这是一个固定的句型结构,that从句里必须用虚拟语气,就是用过去式来表达一个建议。

因此，“是时候去购物了”英语中从句里的动词就要用过去式。即：
It is (high) time that you went shopping .

that从句里的虚拟语气也可用should do来表达，should不能省略。
故：It is (high) time that you went shopping .
=It is (high) time that you should go shopping .

当然，这句话还可用不定式来表达，那就是：It is time to go shopping .

It is time to do sth. “是时候去做某事了/该做某事了”，这是最简单的表达方式。

Answer 2

还是得看语境，一般情况下是用一般现在时的，但如果是直接引语改成间接引语就要变时态了。追答

给你举个例子

"It's time to go shopping", Lily said yesterday. 丽丽昨天说是时候去购物了。

变形就是 Lily said it was time to go shopping yesterday.

Answer 3

不是现在吗。
