The relationship between student and teacher is less formal (正式的) in the U.S. than in many other
countries, especially at the college level. (1) 当老师走进教室时, 学生不必起立. Students are generally
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 _____ to their teachers and
classmates and to be _____ during a test. 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 (作弊).
