I think that when the senior high school entrance examination encounters such a problem, we should first look at the topic, understand the main idea, and then spend five minutes thinking. If you have any ideas, write them down. If egoism is particularly clear, you know at a glance that you will do it, then do it quickly.
If you haven't figured it out after thinking for 10 minutes, check the previous question first to make sure that there is nothing wrong with the previous question, and then come back to do this question, sort out your thoughts step by step and find out the relationship between the conditions.
If you don't have any ideas, you can try to push back and maybe find something.
If you really can't do it and time is running out, you must have the mentality of "Ah Q" at this time. Write down the points you think you can get. If you can get more points, you can get more points. If you write too much, the teacher will not criticize you, and you are afraid that you will miss one or two points if you don't write.
