初一英语现在进行时讲解及练习答案

现在进行时

一、现在进行时

A表示现在( 指说话人说话时) 正在发生的事情(now，at the moment )

What are you doing

I am watching TV now.

B. 表示当前一段时间内的活动或者现阶段正在进行的动作(these days，this week，this month, this term)

I’m reading a history book this month.

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

PS: 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。

PS: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。

二、现在进行时的构成：

现在进行时由"be+现在分词（v-ing）"构成。

Be动词应与主语的人称和数保持一致，即：I am/he/she/it 包括单数名词和不可数名词用is, you/we/they 包括复数名词用are.

The students are listening to the teacher.

He is watching TV now.

三、现在分词的构成

四、（1）一般情况下在动词词尾加ing。

五、go→going ask （问，询问）→asking look→looking

六、（2）以不发音的e结尾的动词，去掉e加ing。

七、have →having take→taking

make（做，制造）→making write（写）→writing

（3）以一个辅音字母结尾的重读闭音节，双写最后一个字母，再加-ing。

get→getting sit（坐）→sitting

put（放）→putting run（跑）→running

swim→swimming begin（开始）→beginning

相关拓展：重读闭音节是指在一个音节中，以辅音音素结尾的而且是重读音节的音节。重读闭音节中元音字母不是发它本身的字母音，而是发短元音。

(4) 特殊形式lie-lying die-dying

The students are cleaning the room now.

（2）否定式：主语+be＋not＋v-ing +其他
