( 改一般疑问句并作肯定和否定回答)_ _3Im playing the football in the playground .(改为否定句)_4Tom is reading books in his study . (改为一般疑问句)_ （1）现在进行时的肯定句转化为一般疑问句以及否定句还没有完全掌握。I am not working.（改为一般疑问句并作出肯定和否定回答）He is runnig or the track.（改为否定句。）The students arent playing football.（改为肯定句）（2）抓住句子中关键词，判断现在进行时。用给出的动词的正确形式填空。1、He _(read) a newspaper in the office now2、 I_(look) after the baby these days.3、 What is ourdaughterdoing?
