一般过去时
1.概念:表示过去某个时间发生的动作或情况。
2.标志词:yesterday, last year, last night, the other day, just now, then, two days ago, in , at that time等。(有时句子中虽然不含表示过去时间的状语,但根据语境可判断动作或状态已经发生,而且与现在没有任何联系,也需用一般过去时。)
一般将来时(will / shall do)
用法:1.be going to do:打算去……,要……
This is just what I am going to say.
这正是我想说的。
2.be about to do:即将、正要,强调近期内或马上要做的事。

5) 有些动词,如:arrive, be close, come, do, done, go, have, leave, open, play, return, sleep, start, stay等,用于一般进行时,并且通常与一个表示将来时间的时间状语连用,可以表示将来时。 例:My mother is coming to visit me next week.(我妈妈下周将来看我。)
现在进行时(be doing)
概念:现在正在进行的动作。
标志词:now, at this moment, look, listen,
过去进行时(was/ were doing)

别担心,你不会认不出她的。她到时会穿一件红色的T恤衫和一条白色的短裙。
注意事项:由于本时态是由将来时和进行时融合在一起的,所以关于本时态的注意事项,可参考"一般将来时"和"现在进行时"的有关注意事项。
现在完成时(have done)
概念:
1.表示某动作发生在过去,强调其对现在的影响。此时用短暂性动词。标志词:already, just, yet, never, before,
2. 表示某动作从过去某时刻开始,持续到现在。此时用延续性动词。标志词:lately, recently, in the past/last few days/years, since then, up to now, so far; since+时间点;for+时间段;

过去进行的结构
过去进行时由"was / were + 现在分词"构成。如:
I was doing my lessons then. 那时,我在做功课。
We were cleaning the house. 我们在打扫房子。
过去将来时态的肯定句、否定句和疑问句形式:
肯定句例句:I was walking down the street when a UFO landed.
否定句例句:I wasnt walking down the street when a UFO landed.
一般疑问句例句:Were you walking down the street when a UFO landed?
特殊疑问句例句:What were you doing when a UFO landed?
初中英语时态知识点:一般现在表过去的用法
1.用于某些动词(tell, say, hear, learn, gather等)表示不确定的过去时间:
John tells me you will leave tomorrow. 约翰告诉我你明天离开。
I hear that he got married last month. 我听说他上个月结婚了。
I hear you want a secretary. 我听说你需要一个秘书。
He says the matter is rather urgent. 他说这事相当紧急。
Mary says you told her to come over here. 玛丽说是你让她到这儿来的。
It really gets me when he says those stupid things. 他说那些傻话真让我生气。
2.当要陈述一个客观事实时,有时即使有过去时间状语也可用一般现在时:
The story is set in the summer of 1937. 故事的背景是1937年夏天。
The story begins in the year 1937. 故事开始于1937年。
运用现在进行时常见的几个错误
1、把动词变成现在分词形式易出错。例:
(1)误:They are swiming (swim) .
正:They are swimming (swim).
(2)误:Jenny is plaiing (play) football.
正:Jenny is playing (play) football.
解析:A、动词变现在分词可有如下口诀:一般-ing;哑e先去e;重闭单辅先双写;-ie结尾y来替。
B、动词现在分词的变化规则要与名词变复数、动词变现单三等规则区分开来。
2、谓语部分的构成不完整:丢掉be动词,或忘记把动词变成现在分词。例:
(1)误:Look! Two children flying (fly) a kite in the park.
正:Look!Two children are flying (fly) a kite in the park.
(2)误:Li Ming isnt read ( not read) a book in bed now.
正:Li Ming isnt reading ( not read) a book in bed now.
解析:现在进行时的谓语部分的构成是"be+现在分词",二者缺一不可,这一点必须要牢记。
3、对动词或动词词组提问时,丢掉代动词doing。例:
The students are singing in the room.(对划线部分提问)
→误:What are the students in the room?
→正:What are the students doing in the room?
解析:现在进行时态中对动作提问可记住此句式"What +be +主语+doing+其它?"或简写为"What......doing......? "句式。
4、现在进行时态的谓语部分是并列结构时,容易忽视第二个以及第二个以后的动词用现在分词形式。例:
孩子们在跑还是在跳?
误:Are the children running or jump?
正:Are the children running or jumping?
解析: or连接的是两个并列成分,动词形式须一致。
现在进行时的三种句式结构
现在进行时在句式的变化上,都应在助动词be上做文章。
1、 肯定式:be(am, is, are)+ Ving(现在分词) 如:
They are having an English class. 他们在上英语课。
2、 否定式:be(am, is, are) + not + Ving(现在分词) 如:
They arent having an English class. 他们不在上英语课。
3、 疑问式:将be的具体形式(即am, is或are)提前到句首。如:
Are they having an English class? 他们在上英语课吗?
助动词变化口诀:变疑问,往前提,句后问号莫丢弃;变否定,更容易,be后not 莫忘记。
初中英语时态知识点:现在进行时结构
现在进行时的结构
现在进行时由“am / is / are + 现在分词”构成。如:
I’m studying at Yu Cai Senior Middle school. 我在育才中学读书。
He is writing on the desk. 他再课桌上写字。
They are talking about their visiting the Great Wall. 他们在谈论游长城的事情。
【说明】动词现在分词的构成方法:
(1) 一般在动词后加-ing。如:say—saying, play—playing, think—thinking, study—studying, teach —teaching, blow—blowing, build—building.
(2) 动词若以-e结尾, 则去e再加-ing。如:love—loving, make—making, guide—guiding, date—dating.
(3) 在以单短元音的重读闭音节结尾,且末尾只有一个辅音字母的动词后,双写最后一个辅音字母,再加-ing。如:begin—beginning, regret—regretting, plan—planning, ban — banning.
(4) 在以ie结尾的动词后,改ie为y,再加-ing。如:lie—lying, die—dying, tie—tying.
(5) 在以-c[k] 结尾的动词后加-king。如:picnic—picnicking, panic—panicking.
现在进行时的应用
现在进行时的应用
(1) 表示目前正在发生或进行的动作。如:
They are planting trees on the mountain. 他们在山上植树。
Mother is preparing supper in the kitchen. 母亲在厨房做晚饭。
(2) 有些非持续性动词的进行时可以表示动作即将进行或发生,或表示动作的重复。如:
He is joining the army. 他要参军了。
They are buying the house. 他们要买那座房子。
(3) 当现在进行时中有always, forever, constantly, continually修饰时,表示说话人的赞赏或厌烦的感情。如:
Why is the baby always crying? 为什么那个老是在哭。
They are always helping us. 他们总是帮助我们。
