【答辩题目解析】
1. Please talk about the differences between the present perfect tense and the simple past tense.
【参考答案】
Well, it is a difficult point to distinguish the present perfect tense from the simple past tense in this lesson. The structure of the present perfect tense is “subject + have + past participle”, which describes the things happened before the things in the past. However, the structure of the simple past tense is “subject+ past tense”，which is used to describe the past things.
2. Please talk about the procedure of the grammar class.
【参考答案】
The procedure of the vocabulary class includes five steps. First, lead-in. Let students concentrate on the class and cultivate their interest to learn. Second, presentation. Help them learn the new grammar. Third, practice. Through practicing, students can master the grammar better. Then, production. It aims to help them to apply what they have learned to the daily life. At last, summary and homework. This is the regular part of the class.
