继续巩固合成词及for, since的 ( http: / / www.21cnjy.com )用法，引出2a内容，然后用多媒体创设情景，通过讲故事的方式呈现延续性动词与非延续性动词在现在完成时中的用法及2b中的生词，并让学生掌握，完成2a，2b。
1. 分组开展竞赛，复习合成词。
2.组织学生仔细观察2a中的图解，引导学生对含有for和since的现在完成时与一般过去时进行区别。
T: Read 2a care ( http: / / www.21cnjy.com )fully, try your best to find the differences between the two sentences in groups.
