What happened to you is almost exactly the same. I am also a student in the key class of Grade One, but I know and understand that I will work hard for my future. Therefore, no matter how sad and sleepy I am, I must, cheer up and listen to the teacher carefully. This kind of life is boring and boring. Many times I don't know how to persist. In our school, cell phones are not allowed, but I still take them secretly. Tomorrow night, everyone will listen to their favorite songs, encourage themselves and stick to it! Cheer up, you still have a lot to finish. I want to laugh, if you persist, how happy your future life will be. If you can't persist, then you are the one who has been eliminated. Sometimes rationality is very important. No matter what kind of adversity you say, you are there. You must stick to the path you choose. Please remember a word, don't forget your initiative, so as to achieve your ultimate goal.
