Generally, it has a certain connection with the examples in the book or the usual simulation questions. After the mock exam, the teacher will probably understand by listening to the examples.

1. You need to know the general layout between the geometric diagram and the function diagram.

2. Analyze what function the problem probably belongs to. (There are usually several functions, and most of the questions asked are not a function, remember. )

3. Make bold description and analysis again, and make many assumptions quickly until they are consistent with the meaning of the question.

In fact, such questions are a waste of time. Make sure the previous questions are correct first, and then study them carefully. Generally, the first one or two questions are simple and naive, while the last one or two questions need to be extended and carefully studied. Remember, don't hang yourself from a tree. )
