教学思路:

    本节课我教的是情态动词cancould能力解时的区别。这节课我打算通过复习以前学过的情态动词can的用法,以及通过做游戏,让学生在轻松愉快的氛围中掌握can的用法,以及了解cancould的区别。

一、teaching content:

topic:unit 5 can you play the guitar?

 grammarusing “can”/ “could” to talk about ability

二、teaching aims:

1.use can  talk about the ability at present.

2.use could talk about ability in the past.

三、teaching key and difficult points:

how to use “can” and “could” to express ability in the present and past.

四、teaching methods:

task-based language teaching method

五、teaching procedures:

step 1warming up

   yes, i could./ no, i couldn’t  ( help him answer)

s1:yes, i could./ no, i couldn’t.

t: we can use “could” t talk about the past

.e.g i can play computer now .but, last year i couldn’t play.
