（1）填表：

（2）如果剪10次，共剪出多少个小正方形？

（3）如果剪了100次，共剪出多少个小正方形？

（4）观察图形，你还能得出什么规律？

My father's day

    My father is a teacher. He teaches Chinese. He likes his job and his students. And the students like him too. He goes to work from Monday to Friday. He does not work on Saturday and Sunday. Every day, he gets up at five thirty. At six, he has breakfast. Then he goes running. He goes to school at seven. He has lunch at school. He goes home at five in the afternoon. At six o'clock, he has dinner. He doesn't watch TV. He likes reading（读）books with me. He goes to bed at nine thirty.
