七年级下教案

Unit 4 Save the trees Grammar：现在进行时

构成:主语+be+动词ing〔现在分词〕形式

I+am+v-ing

we/ you/ they+are+v-ing

he/ she/ it +is+v-ing 定义：现在进行时表示现在或当前一般时间正在进行的动作。

【No. 1】现在进行时的构成

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

【No. 2】现在进行时的应用

(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。

(2)【No. 3】现在进行时的变化

肯定句式：主语+be( am, is, are)+现在分词+其它.

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

一般疑问句：Be(am, is, are) +主语+现在分词+其它？

特殊疑问句：疑问词+be(am, is, are)+主语+现在分词+其它？

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。

有一些特殊变化(或者说以ie为结尾的重读闭音节的动词)的现在分词〔有3个〕,:lying—lie,

dying ―die tying―tie 这些以ie结尾要去e再把I变y再加ing．
