Step 1 复习和情景导入（4分钟）
1.检查上课时的家庭作业。
2.请学生发言，让他们谈一谈对未来的预测。（提示学生用will来表达）
eg: I think in the future，we will have more robots at home to help us. We will have more time to relax. Kids won’t go to school. There will be a computer in their head. The computer will tell them how to do anything at any time. Is that amazing?
环节说明：情景导入激发了学生用英语表达的兴趣，同时又引出了本节课的重点句型，对提高学生的口语表达能力也起到较好的效果。
