1. It seems simple to answer this question: just remember all theorems and formulas, be thoughtful and curious, and do more questions. Actually, it's not. For example, some students can recite the bold words in the book word by word, but they can't use them. Some students do not attach importance to the process of knowledge and methods, and memorize conclusions mechanically; Some students are too arrogant to think and speak, but when it comes to writing and calculation, they are full of loopholes and mistakes. Some students are too lazy to do the problem, and the snow is still falling, slowly turning into a cloud, just like little white cloud. Oh, I was wondering: Is this Snow White the daughter who went to Baiyun that day? Under the cover of darkness, I quietly came to the world, smelled the fireworks and got a little bit of the world red dust. Inadvertent bow, but caused a trace of heart-wrenching pain, the original white snow fell to the ground, disappeared, and even was buried by sewage. Silently sigh: Snowflake, have you ever regretted it? Have you ever been disappointed? You floated happily from the sky to the earth but ended up like this. I stretched out my hands again, trying to catch these simple elves, but only my hands became wetter. I looked up and saw that the opposite roof was a little white. My heart is cheerful again, Xue. Do you want to hide the roughness of this world and give up on yourself? That touch of snow white, I actually look a little crazy. I feel that doing the problem is too hard, too boring and too heavy; Some students did a lot of exercises and read a lot of counseling books, but their grades just couldn't get up. Some students failed to review, learned a paragraph and lost a paragraph.
