阅读下面短文,并根据短文后的要求答题。

      The relationship between students and teachers is less formal in the U.S. than in many other countries,

especially at college. (1)当老师走进教室时,学生不必起立。Students are encouraged to ask

questions during class, to go to the teacher’s office for help after class, and to phone if they can’t go to

school and need help with their lessons. (2)Most teachers allow students to enter class late or leave early,

if necessary.

     (3)However, students are still asked to be polite to their teacher and classmates and to be quiet during

a test. When students want to ask questions, they usually put up a hand and wait. When the teacher or a

student is speaking to the class, it’s rude to talk to another classmate, even in a low voice. When a test is

being given, talking to a classmate is not only rude but also wrong. In the eyes of most American teachers,

students who are talking to each other during a test are cheating.
