How to Behave Well?
In order to build a civilized city, we students should try our best to behave well in the activities.
It's a good habit to keep our clothes clean and tidy. Our city should be kept clean every day. Don't throw litter or spit about. It's good manners to say "Thank you" and "Please" and so on. We should never say dirty words. Be friendly to others and always ready to help the people in need. For example, when we are on a bus, we should give our seats to the old and the women with babies. We should also obey traffic rules. When the traffic lights are red, we should stop. And we'd better not talk or laugh loudly in public.
If everyone behaves well, our city will be more beautiful and more attractive.
提示词：give up concentrate on be (become)interested in
Li Hua spent too much time playing computer games and he fell behind others. As a good friend of his, I must do something to help him.
Firstly, I think it’s very important for him to learn lessons well. He should spend most of his time on his study instead of computer games. Secondly, I must tell him that playing computer games too much is bad for his health, especially for his eyes. So he must give it up. I can play more sports with him after school. Maybe he will become more interested in sports than computer games. And then I'll ask him to concentrate more on his study. Of course, I will try my best to help him with all his subjects. I think I can do it in many fun ways and let him find much fun in studying. At the same time, I'll ask both his parents and our teachers to help him, too. If I try these, I'm sure he will make great progress soon.
提示词语: three years, memories, one of, one day, think, happy/ sorry
How time flies! I have studied in my school for three years. And I will graduate from middle school in a month. I am eager to share my happiness and sadness with you. I had so many memories in three years’ life. One of them impressed me very much. I still remember, when I began to learn English, I found it too difficult. No matter how hard I tried, I still couldn’t do well in it and almost gave it up. As soon as my English teacher found my problem, she had a talk with me about how to learn English well. Since then, she has kept helping me. Little by little, I’ve become interested in English and I’m good at it. I think I am so lucky to become one of her students. I’ve learned a lot from her. I will try to help others when they are in trouble. I think it is a happy thing to help others.
Leifeng was known as a pattern that offered help to others selflessly. He devoted all this life into his beloved career as well. I, myself, was totally shocked by his character.
Such is human nature; people trace the good, water flows to low. Everyone should copy his sprit as our daily life goes instead of uttering a meaningless slogan “learn from Leifeng, our decent idol”, so that we could definitely see a lot more smiling faces rather than conflict.
To help others is not a hard thing, however, what you need is to consist doing it. Take myself as an example. I am the representative of Math, to collect homework is my daily task, however, I would turn them to the right page for shorten the time for teachers when correcting them.
I strongly propose that we shall see a better world if each of us treat Leifeng as our model and copy his spirit.
