Note the usage of the following words used in this lesson:

1. While 上课 was defined as “to start class,” it can also mean “to attend class” as shown by examples such as “因为他们上课一直跟同学说话.”

2. 应该 was originally defined as “should”; however, it can also mean “probably” as shown in the example “老师应该会生气.”

3. 请 has been defined in the past as “Please” and “Invite.” Here it’s also being used in an “ask” context as in “老师要请同学回答问题.”

4. 同学 was defined as meaning “classmates.” However, it more specifically refers to “students in the same class”; which means this term can also be used by teachers and not only by fellow classmates themselves.
