时态导学
1.现在进行时表示正在进行的事情或正在发生的动作。
2.标志词:now,look,listen,It is+时间.
3.现在进行时的句子结构:be(am/is/are)+动词ing(两者同时兼有,缺一不可),如:
(1) I am listening to music now.
(2) The boys are drawing pictures now.
(3) Listen! She is singing an English song.
(4)Look! Mr Li is flying a kite.
(5)It is half past four. The children are going back home.
4.动词-ing形式构成方法如下:
(1)一般情况下,在动词后直接加-ing。如:
go-going,wash-washing,fly-flying
(2)以不发音的e结尾,去e再加-ing。如:
drive-driving,ride-riding
(3)有些单词要双写词尾的字母再加-ing。如:

在现行的广州版小学英语教材中,下列单词的-ing构成属于这种类型:
5t-get,forget,sit,put,cut
3p-skip,shop,stop
