时态(Tense)
时态(Tense)是表示行为、动作和 状态在各种时间条件下的动词形式。 因此,当我们说时态结构的时候,指 的是相应时态下的动词形式。
英语时态分为16种:一般现在、一般 过去、一般将来、过去将来时,以及 这四者的进行时、完成时和完成进行 时。
.
英语共有十六种时态,其表现 形式如下(以study为例):
.
练习:
1、我们每天上六hai
in the east of
China.(上海位于中国的东部)
4、安娜英文写得很好但她说得不好。
5、下一趟汽车下午2点开。
.
二. 一般过去时
概念:表示过去某个时间里发生的动作 或状态;过去习惯性、经常性的动作、 行为;过去主语所具备的能力和性格。
基本结构:①be动词;②行为动词 否定形式:①was/were+not;②在行
.
二. 一般过去时
3) 如果强调已经终止的习惯时要用 used to do
He used to drink. (意味着他现在不喝酒了。喝酒这个
动作终止了) I used to take a walk in the
morning. 我过去是在早晨散步。(意味着现在
不在早晨散步了)
.
二. 一般过去时
3)有些句子,虽然没有表示过去确定 的时间的状语,但实际上是指过去发 生的动作或存在的状态的话,也要用 过去时。
I didn’t know you were in Paris. (因为在说话时,我已经知道你在巴
黎了。这句话指的是说话之前,所以 只能用过去时表示。实际上,这句话 暗指:But now I know you are here.)
基本结构:①be动词;②行为动词
否定形式:①am/is/are+not;②此时态 的谓语动词若为行为动词,则在其前加 don't,如主语为第三人称单数,则用 doesn't,同时还原行为动词。
一般疑问句:①把be动词放于句首;② 用助动词do提问,如主语为第三人称单 数,则用does,同时,还原行为动词。
一. 一般现在时
概念:表示通常性、规律性、习惯性的 状态或者动作(有时间规律发生的事件) 的一种时间状态。
