Teaching Reflection　【教学反思】 In this period, we should practice the key structure and the clause carefully in reading and speaking activities. We must learn some new words and expressions in reading, and it is necessary to get the students to pay enough attention to the verbs and their forms. When we learn grammar, we get the students to read enough sentences and sum up the main structures and compare the different tenses. Students can practice grammar by using the language. The students should practice in different activities. And we’d better have them write their own sentences and tell their own stories. In this way they may practice the tenses and the structures. 学科网（北京）股份有限公司 $
