Skills to do the last question:
1。 Most of these questions are three or four. And context. If you can't do the first question, or do it wrong, you will lose everything. It is important to do the first and second questions well.
2。 The first question is simple, but there are many analytic expressions. The basic concepts must be well used in the function foundation. The nature and significance of linear function, inverse proportional function and quadratic function should be well understood.
3。 The second problem is to find the moving point or area.
The moving points are mostly in the same direction, multi-direction and opposite direction at the same time, but they are all at the same time on the whole, which is easier to do. An unknown number can be set, and the equation can be listed by calculating the formula of the travel problem.
If you want to turn a little movement into a static bitmap, you can draw more pictures according to the meaning of the question, which is very helpful to understand the meaning of the question.
Find the area: mostly the combined area. To remember the formulas for calculating the area of triangles, quadrilaterals and polygons and their properties, the concepts of similarity and congruence are sometimes used, and the basis of triangles is the key point.
4。 The third question is more about expanding divergent thinking on the basis of the second question. Only by summing up the laws of the previous questions can we do the third question well. We usually practice this kind of problem a lot.
5。 Asking the fourth question is even more abnormal. This question is not very difficult. Mainly focus on multiple solutions. It is common for some problems to have four or five solutions. Usually, you should do such questions with a normal heart, so you won't hesitate when you take the exam.
6。 Remember to have confidence in yourself (which is also the most important thing), it is difficult for you, and it is the same for others. Concentrate. Also set aside time to check, otherwise it will be done in vain.
7。 Remember, inspection is also important.
8。 Do the same thing at ordinary times, don't be afraid of questions, ask questions frequently, and use your head to sum up the rules.
9。 Don't practice too difficult, too biased and too weird questions. This kind of problem is rare. Asking too many questions is asking too many questions. Most of them can't. Don't take it too seriously.
If you really can't do it, forget it. You can get high marks if you do well in front.
The topic of moving should be considered comprehensively.
The first two questions are usually relatively simple, so we should pay attention to the connection between the first two questions and the last one.
