When read the paragraph 5, I know that the benefits of being good-looking do not spring entirely from one's being sexually attractive. I think person prefer attractive person to unattractive person is a nature activity. Because the pure children are favorably biased the attractive children. So I agree with the author. I think if I am the teacher, I will do the same thing with the teacher.
When I read the paragraph 6, I was puzzled by “to top it off”,and I fund [found]it in the dictionary, it meansin addition, usually something esp. Good or bad. In this sentence it means that people not only like attractive persons more, but also think that attractive people, more than unattractive people, are guessed to have personalities like one's own. I find the findings point to a physical- attractiveness stereotype is accepted by more and more person, the good look person have much better conditions.
