北师大版初一(下)英语第4讲：Unit Two 语法篇(教师版)--顺义刘燕

Unit Two 语法篇____________________________________________________________________________________________________________________________________________________________________ 重点掌握现在进行时的用法重点语法：现在进行时一、概念表示正在发生的事情或动作，常和now，look，listen连用。

二、句子结构1．be + 动词现在分词（即：动词-ing形式），be + doing 是一个整体，不能分开。

2．be 随着主语的变化而变化，doing的变化规则根据现在分词的变化规律来定。

三、动词现在分词的构成规律1．一般情况下,在动词原形后直接加-ing；如：work→working do→doing play→playing 2．以不发音字母e结尾的动词，先去掉e，再加-ing；如：dance→dancing e→ing3．在重读闭音节（即：辅音＋元音＋辅音）的动词中，要先双写末尾的辅音字母，再加-ing；如：get→getting shop→shopping run→running swim→swimming4．以ie结尾的重读闭音节词，将ie改成y再加ing。

如：lie→lying die→dying四、现在进行时的各种句式变化现在进行时的肯定句（1）第一人称：主语+ am + 现在分词+ ……（2）第三人称单数：主语+ is + 现在分词+ ……（3）第二人称及复数人称：主语+ are + 现在分词+ ……现在进行时的否定句句型：主语+ 相应be动词+ not + 现在分词+ ……现在进行时的一般疑问句句型：相应be动词+ 主语+ 现在分词+ ……？现在进行一般疑问句的答语（1）肯定回答：Yes, 主语+ 相应be动词。

（2）否定回答：No, 主语+ 相应be动词+ not。

现在进行时的特殊疑问句句型：特殊疑问词+ 相应be动词+ 主语+ 现在分词+ ……？现在进行时特殊疑问句的答语回答特殊疑问时，根据不同的疑问词的情况来决定回答方式。

回答what提问时，答语是现在进行时的肯定形式；回答who提问时，只需说明主语是谁，再加相应的be动词即可。

1.Look! She is ________ his red sweater .A. putting onB. puting onC. put inD. put on2. That boy isn’t ________ the teacher .A. listenB. listensC. listeningD. listening to3.It’s eight o’clock.

2.listen to 是固定搭配，又有系动词is，不能用动词，所以用listening。

3.从现在八点可以看出动作正在进行，用现在进行时，故用动词ing,前面是父母，所以用复数。

4.从at the moment 判断出是现在进行时，做蛋糕用make,为某人做用介词for.5.句子中出现了are,所以不能用动词，只能用动名词D。
