现在进行时
基本用法

eg:---What are you doing?
---I am reading a book.
,但此刻动作不一定正在进行
eg:He is teaching at the school.
We are learning Unit5 these days.
,或在句首常出现Look! Listen!等提示词
eg:Listen! Danny is singing in the room.
He is doing his homework now.
结构: be+doing ( be要根据主语作人称和数的变化)
句型转换
,要在 be 后加 not 构成
eg:We are reading English now.
We are not reading English now.
,把be动词提到句首
eg:The student is drinking.  Is the student drinking?
,由“疑问词+一般疑问句”构成
eg:He is working.  What is he doing?
现在分词的构成
–ing eg:look looking
,则去e加-ing
,且末尾只有一个辅音字母的,应双写此字母,再加–ing. eg:sit sitting
口诀教你学doing
进行时很好记,be加动词-ing;
直加双写去哑e,分词构成须仔细;
别说 be 无词义,主语和它最亲密;
变疑问 be 提前,否定 not 再后添;
何时要用进行时 look,listen,now标志.
