时态讲解(一)
现在进行时用法。
一、定义:1、表示说话时正在进行的动作及行为2、表示现阶段正。
在进行的动作。
二、结构:现在进行时常有三种句型:
1)肯定式:主语+be+v-ing+其它。如:he is mending his bike.他正在修自行车。
2)否定式:主语+be+not+v-ing+其它。如:
he is not(isn't)mending his bike.他没在修自行车。(3)疑问式:主要分一般疑问句和特殊疑问句两种句式。
一般疑问句:be+主语+v-ing+其它?如:
—is he mending his bike?他正在修自行车吗?—yes,heis.(no,he isn't.)
特殊疑问句:疑问词+be+主语+v-ing+其它?如:
what is he doing?他正在干什么?
三、何时用现在进行时?
1)以look!或listen!开头的句子提示我们说话时动作正在进行,应用现在进行时。如:
look!the children are playing games over there.listen!who's singing in the classroom?
2)当句子中有now(现在)时,常表示说话时动作正在进行,这时也常用现在进行时。如:we are reading english now.
3)描述**中的人物的动作时常用现在进行时,以示生动。如:look at the picture.the girl is swimming.(4)表示当前一段时间内的活动或现阶段正在进行的动作时常用现在进行时。
这时常与时间状语these days,this week等连用。如:
we are playing football these days.这些天我们在踢足球。(5)有时句子中可能没有时间状语,但如果表示的是说话时或者现阶段正在进行的动作,就应该用现在进行时。如:
—what's jim doing?吉姆在干什么?—he is cleaning the room.他正在打扫房间。
注意:是不是所有的动作都可以用现在进行时?
不是。有一些表示状态、结果、感觉和感情的动词,如h**e(有),be(是),like(喜欢),know(知道),want(想要),think(认为),see(看见),hear(听见),forget(忘记)等,一般不用现在进行时。如:
i h**e a new bike now.现在我有一辆新的自行车。但不说:i'mh**ing a new bike now.
四、有些动词的现在进行时表示近期按计划或安排要进行的动作。go,come,le**e,start,arrive,return,work,sleep,stay,play,do, h**e,wear, die等。如:
she's coming to see me tomorrow.她明天要来看我。the football match is starting next monday.

一般现在时和现在进行时的区别。
一般现在时表示经常性的动作;而现在进行时表示暂时性的动作。he walks to work.
他步行上班。(习惯、经常性的动作)

他家住在哪儿?(询问一般的情况)where is he living(staying)?他这几天住在哪儿?(询问暂时一段时间的情况)
6现在进行时有时可用来代替一般现在时,表达说话人的某种感惰,使句子有强烈的感**彩。常与always,forever连用。you are always forgetting the important thing.
你总是把重要的事情忘掉。(表达出不满的情绪)mary is doing fine work at school.玛丽在学校学习得挺不错。
比mary does fine work.更富有赞许的意思)
