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,he is.(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)描述图片中的人物的动作时常用现在进行时,以示生动。如:

(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?

不是。有一些表示状态、结果、感觉和感情的动词,如 have(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 have a new bike now.现在我有一辆新的自行 车。但不说:I'm having a new bike now.

She's coming to see me tomorrow. 她明天要来看我。

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,使句子有强烈的感情色 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)
