现在进行时1.定义：现在进行时表示正在发生或进行的动作。

结构是：be (am, is, are)+动词现在分词形式。

（简写：be +动词-ing）A、陈述句(肯定句)主语＋be (am, is, are)+现在分词，如：I am reading English.我正在读英语。

He is writing.他正在写字。

B、一般疑问句Be(Am, Is, Are)+主语＋现在分词，如：Are you singing?你正在唱歌吗？C、特殊疑问句疑问词＋be (am, is, are)＋主语＋现在分词What are you doing? 你正在干什么I am doing my homework.我正在做作业。

2.标志词：(1) 时间状语 now 、at the moment(2) 句前有提示词look 、listen 、look at …3.动词-ing的构成规则（1）一般情况下，直接加ing，如：cook-cooking（2）以不发音的e结尾，去e加ing，如：make-making, taste-tasting（3）如果末尾是一个元音字母和一个辅音字母，双写末尾的辅音字母，再加ing 如：run-running, stop-stopping（4）以ie 结尾的动词，先把ie变成y 再加-ing。

lie- lying tie -tying die-dying注意： see-seeing draw-drawing listen-listening现在分词构成口诀现在分词很好记，动词后缀-ing。

直接加、去e加、双写加。

还有一点要注意ie要用y来替。

现在进行时用法口诀主语在前be在后，现在分词跟着走，其他成分不可丢。

变一般很简单，把be 提到句子前，否定句也不难，be后要把not添。

还有一点要注意，动作提问doing替。
