英语时态的语法总结

【基本用法】

“过发现影”--- 表示过去发生，对现在造成了影响。

e.g. Their parents have known the good look excited.

“过发持续”--- 表示从过去开始，持续到现在的动作或状态。

e.g. I have learned English for 10 years.

“经历” --- 表示曾经做过某事，或曾做过n次

【时间状语】

already, just, yet, since, since then, for, recently / lately,

so far = till / until now = up to now, in the last / past few years,

How long…ever, never, before, once, …times

【重难点】

延续性与非延续性动词的用法

什么时候才必须用延续性动词？ 出现how long, for+时间段, since+时间点

非延续性动词转化

▲ 高频考点

borrow → keep buy → have

finish / end → be over begin / start → be on

open → be open die → be dead

join → be in / be a…member leave →be away（from）

▲ 需了解记忆

get up → be up fall asleep → be asleep

fall ill → be ill, lose → be lost

become → be return / come back / get back → be back

close → be closed catch / get a cold → have a cold

arrive /come / go / move / reach /get to → be in /at / be here /be there

【易错点】

in the past few years (不是 a few)

have been to, have gone to和have been in的区别

already与yet区别

since+时间点，for+时间段（since 3 years ago; for 3 years）

since 引导的从句要用一般过去时

It is /has been + 时间段 + since + 从句（一般过去时）

He came to our school in 2000, since then he has taught English here.
