七年级英语下册
Unit5 语法和写作
一、语法
现在进行时
（一）用法：
1.表示说话时正在进行或发生的动作。
2.表示当前一段时间内的活动或现阶段正在进行的动作。
（二）构成：
主语 + Be动词 + 动词现在分词
动词现在分词变化规则：
1.一般情况下，直接加ing
Eg：work -- working
2.以不发音的e结尾，去e加ing
Eg：take -- taking
3.在重读闭音节中（单词中总有一个元音，元音后只有一个辅音）
Eg：stop -- stopping
4.以ie结尾的动词变ie为y加ing
Eg：die -- dying ; lie -- lying
（三）现在进行时的句型变化：
肯定句：They are talking on the phone. 他们正在打电话。
否定句：They aren’t talking on the phone. 他们没有在打电话。
一般疑问句：Are they talking on the phone 他们在打电话吗？
肯定句：Yes, they are. 否定句：No, they aren’t.
特殊疑问句：What are they doing
注意：表示位移动词，如leave, move, go, come等，常用现在进行时，表示动作将要发生，而不表示动作正在进行。
Eg：My family is moving to Beijing next month. 我的家人下个月要搬到北京了。
（四）现在进行时时间标志词：
now(现在)，at the/ this moment(此时此刻)，Look! (看)， Listen!(听)等。
Eg：I am doing my homework now. 我现在正在做作业。
They are listening to music at the moment. 此刻他们正在听音乐。
Listen! Someone is singing in the next door. 听！有人在隔壁唱歌。
