英语语法入门之过去时态

  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.
