一个学生找老师因为他要写的bird migration的报告，但找不到足够多的材料，老师认为不可能材料不够(出现考点：问教授这话什么意思，答案是她认为找resource应该easy)，男生说因为他要写得paper是关于古代鸟类迁徙的，所以资料不够。教授的说：“哦你确实找到了一个好的题目，但是你要知道我的要求是你们的论文要反映你们这学期学了什么。”后来他说想写关于Aristotle关于这个题目的看法之类的，老师说她的要求是希望他们运用所学知识研究来完成paper 不要做summarization,希望他换一种想法,可以写以前的old theory, 然后现在的这些新研究如何支持或者驳斥这些theory，接着他想到可以写bird migrate at night，人们大多只看到大鸟，所以认为小鸟在大鸟的翅膀下迁徙什么的，其实新发现是因为小鸟晚上飞(通过说这个topic来验证自己理解了老师的意图change the topic from ancient to recent)。后来他又想写一种不迁徙而是冬眠的鸟，又被老师拒绝了，老师说才15页的报告就不要那么折腾成这样，但是想法挺不错。最后老师希望他一周后再来一下，看一看他确定的方向。
People think small birds do not migrate. But birds migrate at night and the small birds are under the wing of big wings. So they are invisible to people. Then the student wants to write a bird that not migrate but hibernate, but the teacher denies his idea. At last, the teacher hopes that he can come a week later and see his new topic.
He can not find sufficient material for the bird migration. But the teacher thinks it is impossible. They he wants to write some ideas from Aristotle. But the teacher says that her request is to apply their knowledge to accomplish the paper. So he should change the topic.
祝大家：Merry Christmas ！
