专题十 现在进行时
1、概念
表示正在发生的事情或动作，常和now，look，listen连用。 如：We are listening to music now. 我们现在正在听音乐。 Listen! He is playing the piano. 听！他正在弹钢琴。 2、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。 3、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 come→coming
3)．在重读闭音节（即：辅音＋元音＋辅音）的动词中，中间只有一个元音字母，词尾只有一个辅音字母，要先双写末尾的辅音字母，再加-ing；
如：get→getting shop→shopping run→running swim→swimming 4)．以ie结尾的重读闭音节词，将ie改成y再加ing。 如：lie→lying die→dying 4、现在进行时的各种句式变化
肯定句： 主语 + be + 现在分词V-ing (+ 其他) 例如：I’m doing my homework now . 否定句：主语+be+not+动词-ing +其他. 例如：I’m not doing my homework now.
一般疑问句：Be+主语+动词-ing +其他? 例如： Are you doing your home work now? Yes, I am . No , I’m not . 特殊疑问句：特殊疑问词+be+主语+动词-ing+其他? 例如:What are you doing now ? ◆课堂练习：
