2021届河北衡水高三英语新高考语法学习笔记(06)时态和两句连接方法知识点概要
时态
· He writes a letter.
· He comes back.
这两个例子无时间副词修饰,所以不是习惯性的动作,因此无意义
· He who is lazy is doomed to failure. to是介词
· He who is lazy is doomed to fail.
begin start arrive leave come go 等动词可用一般现在时表将来
· They arrive tomorrow.
· The meeting begins at 7.
· They start the day after tomorrow.
· Does he come tomorrow?
表示过去经验可用一般过去时,现在完成时也可以
Did you ever see her before?
=Have you ever seen her before?
你以前见过她吗?
句中若有after until before 等连接词引导的从句,由于时间先后很清楚,可用一般过去时代替过去完成式
· After I finished the work, I went home.
· I didn’t study English until I was 10.
· Before I moved here, I lived in Japan for a long time.
when unless if once等引导的状语从句表示条件时,要用一般现在时,主句用一般将来时
· When I have money, I will buy a car.
· I won’t buy a car unless I have money.
· If I see him, I will tell him the truth.
He told me that he had seen the movie once.
He was angry because he hadn’t seen Mary.
过去完成式不能单独存在,要与另一一般过去时从句或表过去的副词短语连用
He will have arrived in Chicago by this time tomorrow.
When you come, everything will have been finished.
He was dying.
He was going to die.
He was about to die.
主句为一般过去时时,从属从句不得用表现在或将来的时态
I thought he had been working hard.
for/during/in/through/down through/over the past/last five years 过去五年来=since five years ago
这些短语与现在完成时或现在完成进行时连用
I have been studying English for the past two weeks.
since表自从,作介词,后面接名词或动名词
since后还可以引导一般过去时的状语从句,主句应用现在完成时或现在完成进行时
· I have lived here since 2000.
· I have been studying English since I went to college.
since 之后必须接明确的某时间作宾语,不可以接一段时间作宾语,若接一段时间,需要在一段时间之后接ago
Peter has lived here since two years ago.
现在完成时和现在完成进行时与for+一段时间连用时,该动词所表示的动作必须可持续进行
He has died for two months. 错误
He has married Jane for twenty years. 错误
It is three years since he died.
It is twenty years since he married Jane.
