英语语法入门之过去时态
英语时态很多同学会搞混，下面我整理了英语语法入门之过去时态知识，希望对大家有帮助！
There are two tenses in English – past and present.
英语里有两种时态—过去时和现在时。
The past tense in English is used:
英语里过去时用于：
to talk about the past
谈论过去
to talk about hypotheses – things that are imagined rather than true.
谈论假设
for politeness.
基于礼貌
There are four past tense forms in English:
We use these forms:
to talk about the past:
He worked at McDonald’s. He had worked there since July.
He was working at McDonald’s. He had been working since July.
to refer to the present or future in conditions:
He could get a new job if he really tried.
If Jack was playing they would probably win.
and hypotheses:
It might be dangerous. Suppose they got lost.
I would always help someone who really needed help.
and wishes:
I wish it wasn’t so cold.
In conditions, hypotheses and wishes, if we want to talk about the past, we always use the past perfect:
在条件状语从句、虚拟语气以及表祝愿时，我们在谈论过去时，经常使用过去完成时。
I would have helped him if he had asked.
It was very dangerous, What if you had got lost?
I wish I hadn’t spent so much money last month.
We can use the past forms to talk about the present in a few polite expressions:
在一些礼貌的`表达中，我们用过去式来谈论现在的事情。
Excuse me, I was wondering if this was the train for York.
I just hoped you would be able to help me.
