What is the most common mistake that experienced teachers often make?
Do you agree or disagree with the statement: we should always be honest with our friends.
Notice: The writer of letter proposes that sleeping in the library should be banded. Because sleeping students take up too much space, also, that behavior gives others a bad impression
【学生态度】：The man disagree
Reason 1: This behavior cannot take negative influence on students, there are enough tables and space, and they can find their preferred one.
Reason 2: It will not leave a bad impression on others. For example, he joined a tour group and also saw students sleeping in the library. The student just take a nap when he felt tired, the spirit of saving time leaves a good impression as long as you do not sleep all the time.
Question: Explain the man’s opinion and why he holds that opinion.
The reading is about an academic topic known as flip-classroom method, which refers to a method different from the traditional ones in which the teachers assign video course to the students before the class and teach them how to solve their difficulties in the class.
Example 1: One of the professors’ friends, a high-school math teacher used to teach concepts in the class and gave students homework to finish after the class but they didn’t do it well or even didn’t know how to do it. So the teacher changed her way of teaching. She first recorded the video of explaining the concepts, uploaded to the internet, and asked the students to watch on their own. And then in the class, they would do harder ones and she would solve the students’ problems immediately in the class, which was proved to be quite useful.

【讲课要点】：In the lecture, the professor talks about two ways the caterpillars protect themselves from injury.
Firstly, they do it by their specially-modified physical features. These features make it hard for their predators to eat them. For example, the skin of the caterpillars is very rough so when a bird catches it bites it and tries to swallow, but the bird will find it impossible to do that because of the rough skin. As a result, the birds won’t prey the caterpillars any more.
Secondly, they will take advantages of other animals to protect themselves. The cat-pillar will create food for some animals so these animals will help protect them from the predators. For example, the caterpillar secretes some liquid that the ants love to eat. So when the predators of the caterpillar are approaching them, the ants would bite or attack the predators and thus protect the caterpillars.
