In addition to paying attention to basic knowledge, we should also pay attention to strengthening the cultivation of our own mathematical sensitivity in the review process. This includes observation and induction. Two triangles form a butterfly diagram, two line segments form a right angle, and three perpendicular lines appear in a square. Many ideas come from our careful observation when doing a good job. This ability is highlighted in the last question in the blank and the 22nd question in the answer.
To put it bluntly, these questions are testing everyone's observation ability, discovery ability, induction ability and application ability. In the case that the basic knowledge has been reviewed almost, we should have a pair of keen eyes and a good inductive mind for these problems. The outstanding point of these two problems is change. We should be good at finding the unchangeable things in the process of change, whether it is graphic change, condition change or digital change, there are always unchangeable things among them. Either the thinking of solving the problem remains unchanged, or the auxiliary line drawing method remains unchanged, or the relationship between the two quantities remains unchanged, or the conclusion remains unchanged.
We observe the figures, observe the conditions, and observe the conclusion drawn from the previous question. There will always be a line to string them together, which provides a good idea for us to do the next question. Therefore, in this review stage in spring, training your observation ability and induction ability will help you find a way of thinking faster and more accurately.
Next, let's talk briefly about mentality. No matter whether your grades are good or bad now, our spring review is to improve your grades and ensure that your grades are as stable as possible. In addition to studying at home on weekdays, relax and talk to your parents about things other than study, and combine work and rest. But be careful not to be disturbed by other trifles.
