01 概念
表示正在发生的事情或动作，常和now，look，listen连用。
eg：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。
02 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。
03 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;
eg：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;
eg：dance→dancing come→coming
3.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;
eg：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。
eg：lie→lying die→dying
04 现在进行时的各种句式变化
1.否定句
方法：直接在be的后面加not。
eg： They are running. →They are not running.
2.一般疑问句
方法：直接把be放在主语的前面，其余位置不变。
eg：：They are running. →Are they runnin?
3.特殊疑问句
方法：如果就划线部分提问事情或动作时，用What…doing?
eg：They are swimming in the sea now.
→What are they doing in the sea now?
