In English class,we often have group practices.How can group activities help us study english better?
Here （are 改为is）some advice：
We must make it clear (and多余去掉 )what the mission for each group（ 加is ）and how it should be done.The group numbers must know what (they 改为to) do.The different roles have different (duty改为duties).Think and work （with one heart and one mind改为wholeheartedly）.
（Teacher should of necessary改为If necessary,the teacher should） （help改为offer help） to each group during activies.
The activity （mission 可以去掉）report must be shared in class,because they are our （classmate改为classmates）.
If we (try改为follow) （these改为the） advice,we probably (incrase改为increase) our English（加learning） skills.
