Jack is swimming.看！杰克正在游泳。 Listen! She is singing.听！她正在唱歌。 I am cleaning my room now.现在我正在打扫房间。 听了"我"的自述后，小朋友们，你们一定更加了解"我"了吧。 练习 I. 写出下列动词的-ing形式 run ________ swing ________ jump ________ write ________ do ________ answer _________ read ________ draw ________ cook ________ make _________ talk _________ answer ________ wash _________ go _________ fly ________ take ________ carry ________ ask ________ sing ________ begin ________ stop ________ get ________ grow ________ buy ________ II. 用所给的动词的正确形式填空 1.
