Step2 Presentation
1. T: Just now you talked about Mike and his family. Here are some sentences of them.

2. 学生自己来总结行为动词的过去式构成：
① 一般情况是在动词后加ed，如：snow---snowed
② 以不发音的字母e结尾的动词直接加d，如：like---liked
③结尾是“辅音字母+y”的动词，先变“y”为“i”再加ed，如：study---studied
④末尾只有一个辅音字母的重读闭音节词，先双写这个辅音字母，再加ed，如：stop---stopped
⑤不规则变化，见书P39：can--could， get---got， do---did, fly--flew, go--went;
see---saw ;eat---ate, take--took，read--read

could/couldn’情态动词t+动词原形， did/didn’t助动词+动词原形
3. 反馈预习自测语法机械训练结束，是否应该联系生活让孩子运用所学的词谈一谈身边的变化？

Step3 Consolidation
