现在进行时用法专题

一，现在进行时的构成

现在进行时由"be+v-ing"构成。初学者最容易漏掉期中的be动词，它应与主语的人称和数保持一致。

二，现在进行时的应用

在实际运用时，现在进行时常用以下几种情况：

(1) 当句子中有now时，常表示动作正在进行，这时要用现在进行时。如： They are playing basketball now.现在他们正在打篮球。

(2) 以look, listen开头的句子，提示我们动作正进行，这时要用现在进行时。如： Listen！She is singing an English song.听，她正在唱英语歌。

(3) 表示当前一段时间或现阶段正在进行的动作，且此时有this week, these days等时间状语，这时常用现在进行时。如：

We are making model planes these days.这些天我们在做飞机模型。

(4) 描述图片中的人物的动作，也为了表达更生动。此时也常用现在进行时。如：

Look at the picture. The children are flying kites in the park.看这幅图，那些孩子正在公园放风筝。 (5) always, forever,constantly(不断) 等词多出现在现在进行时中，带有一定的感情色彩。 He's always quarrelling with others. 他老喜欢跟别人吵架。

She is constantly worrying about her son's health. 她不停地为她儿子的健康担心着。 The boy is forever asking questions. 那个男孩老是问问题。

(6) 现在进行时表示“逐渐”的含义。此种用法除了偶尔和now连用外，一般不和其他时间副词连用的。 Our study is becoming more interesting. 我们的学习变得越来越有趣了。 The leaves are turning red. 树叶渐渐地变红了。

(7) 有时现在进行时表示将要发生，是一般将来时。 例：I am coming. 我马上就来（将会来）

He is leaving Wuhan for Beijing. 他将离开武汉去北京（将离开） What is Jim doing on vacation? 吉姆度假打算做什么？（将做什么）

三，现在进行时的变化

肯定句式：主语+be( am, is, are)+现在分词+其它. He is watching TV now.

否定句式：主语+be(am, is, are) +not +现在分词+其它. He is not watching TV now.

一般疑问句：Be(am, is, are) +主语+现在分词+其它？ Is he watching TV now? Yes,he is/No, he isn’t. 特殊疑问句：疑问词+be(am, is, are)+主语+现在分词+其它？ What is he doing now? 对现在进行时的特殊疑问句的回答，它不可以用Yes或No直接作答，要根据实际情况回答。 Please don't make so much noise. I'm writing a composition. 不要吵闹。我正在写作文。 Let's set off. It isn’t raining now. 咱们出发吧。现在不下雨了。

Where is Kate? She is reading in the room. 凯特在哪里？她在房间里看书。

四．现在分词变化规则： 1 ).一般情况下直接加ing

think---thinking sleep---sleeping study---studying speak---speaking say---saying

2) .以不发音的字母e结尾的单词，去掉字母e，再加ing

wake---waking make---making come---coming take---taking leave---leaving have---having dance----dancing ride----riding write---writing

3.)以重读闭音节结尾，呈现“辅，元，辅”结构的动词，先双写末尾的辅音字母，再加ing.如：


begin，cut, get, hit, run, sit, stop, set, swim, fit, dig, forget等

stop---stopping sit---sitting run---running forget---forgetting begin---beginning

4). 以ie结尾的动词，把ie改为y ，再加ing lie---lying die→dying
