I have a best friend named Nha, we have been together since we were just little kids. She has beautiful bright skin and big black eyes. We have a lot of things in common, such as we love the same band, food and books. She and I even share the same name, and it is a small surprise for anyone who has talked to us. Nha is not my classmate, but we always help each other with the homework and school projects. We spend every minute in our break time to talk about all the things that happen in class, and people usually ask what can even makes us laugh that hard. Sometimes I think it is we have been best mates since forever, and I hope that we will be happy this for a very long time

Tôi có một người bạn thân tên Nhã, chúng tôi đã chơi cùng nhau kể từ khi còn là những đứa trẻ. Cô ấy có một làn da trắng rất đẹp và đôi mắt lo đen láy. Chúng tôi có nhiều điểm chung, ví dụ như tôi và cậu ấy thích chung một ban nhạc, thức ăn và sách. Tôi và cô ấy thậm chí còn có chung tên, và đó là một điều ngạc nhiên nhỏ cho những ai từng nói chuyện với chúng tôi. Nhã không phải là bạn chung lớp với tôi, nhưng chúng tôi luôn giúp đỡ nhau làm bài tập về nhà và những dự án của trường. Chúng tôi dành từng phút của giờ nghỉ trưa để nói về mọi chuyện ở lớp, và mọi người thường thắc mắc điều gì có thể khiến hai chúng tôi cười nhiều đến vậy. Đôi khi tôi nghĩ rằng chúng tôi đã là bạn thân từ rất lâu rồi, và tôi hy vọng chúng tôi sẽ luôn vui vẻ như thế thật lâu nữa

2.Enviroment is the most important thing for our life. Enviroment is the air we breath, the water we drink and is everything we need for our life. But now that most important thing for our life is being polluted and by many different ways. This pollution affects the health of living things. Air is damaged by car and lorry fumes, and power stations create acid rain which destroys entire forests and lakes. When fossil fuels i.e. oil, gas and coal are burned to provide energy for lighting, cooking etc. they form polluting gases. Not only on land but also in the sea, oils spills pollute sea water and kill marine life; chemical waste from factories and sewage works, and artificial fertilisers from farmland, pollute river water, killing wildlife and spreading disease. Everything is being caused by human’s existence. Humans create such a lot of rubbish! Each household produces about 1 tonne of rubbish every year! Most of this is taken away by dustmen and buried in enormous landfill sites or burned in incinerators - both of these actions can be dangerous for the environment.
But only we can change it and solve it. Pollution can be prevented by thing we do everyday. First we can use recycled paper to help save trees. Second try to avoid buying plastic. It's hard to recycle. One way to cut down on plastic is to refuse to use carrier bags. If we can’t avoid buying plastic bags, we should use re-use plastic bags over and over again, until they wear out. Finally we should take your old clothes to charity shops, some are sold. To protect environment we also have to save energy. Use less energy by switching off lights when rooms are not in use, not wasting water; don’t forget to switch off all electric things when they are not in use, use a bicycle or walk instead of using a car for short trips we can save energy, keep clean atmosphere and keep healthy life. Lighting accounts for 10 percent to 15 percent of the electricity bill. However, this amount can be reduced by replacing an ordinary 100-watt light bulb with an energy-saving bulb and we still trying to invent the new thing to save money as well as conserve the Earth’s resources.
Keep clean environment isn’t only all ways are mentioned before but also to protect natural resources. That is the way to conserver wild life. First we need to conserve the old forest, rainforest, build more safari and national park, and plant more trees to make place to live for wild animals. Second we need to prohibit hunters who hunt animals too many out of the law allowance.
Finally, we now know that enviroment is the most important thing for life and we know how to protect and use it scientifically. Everyday we invent and find more and more way to protect enviroment. I hope that in the future the earth will be cleaner.
First of all, some of the largest problems now affecting to the world, air pollution and hazardous waste. These issues can be avoided with the recycling, for example in order to reduce pollution, we can minimize the energy spends on industrial production. Consequently, the greenhouse emission can be reduced which are harmful for the environment and our health. Furthermore, most of the landfill sides are filled up with a lot of waste products that could have been recycled, especially waste materials that belong to non-biodegradable category which takes a long time to discompose. In this way, recycling enable proper usage of these waste products and saves space for landfill.
Plant more trees. This is easy, you know? Choose an open area/ground near your residence or workplace. Plant a tree every month, encourage your friends and colleagues to join you. Have more and more trees planted and there will come a day when you have a green stretch of land thanks to your effort.
Walk more, drive less. Now that's not very difficult, is it? Choose to walk short distances instead of taking your car every time. Walking to the gym, to work (if it's not very far), go walking to run errands. Or use a bicycle. Both cycling and walking are good exercises. And each time you avoid using your car, you are contributing to reducing air pollution. You are saving fuel, saving money and getting a good workout too.

My best friend in high school is Lan. Lan sits next to me in class, eats with me at break time, and hangs out with me after school. She has long and beautiful hair; my mother always says that I need to pay more attention to my hair so it can be pretty as hers. I am good at English while Lan is excellent in Math, therefore we can help each other every time one of us has trouble in understanding those subjects. Besides our study, Lan is always by my side whenever I feel upset. I tell her everything, and only her can know my true feelings. We have been best friends since our young age, and I will keep this friendship forever.
I have a bestfiend and also a neighborhood whoes name is Tuan. His age is the same as mine but he looks older than me. Because he’s very tall and thin, everybody calls him “a palm”. Tuan has a short curly hair and beautiful chestnut brown eyes that appeal of many girls. He is a person of very few words that makes him to be a good listener. Anyone, who has ever contacted with Tuan, thinks about him as a glacial boy. In fact he’s really warm and nice. He’s willing to help people whenever possible. When I was in secondary school, I found Math was very difficult to understand but Tuan solved the Math problems so fast. He spent all seven nights of weeks to help me in Math while he could go out to relax. Tuan was a good all-rounder exception English. Most of the teachers in school and parents highly appreaciated his talent. Only a month ago, he received two full scholarships from America Government to study oversea but he has not yet decided whether he should go or not. Although he has not spent much time to take part in sport activities, he is a well football player. We were in Ha Noi Young Football Team when we were in grade 10. Everything seems perfect to my bestfriend but he’s very modest and always talks to himself to give more effort. I’m proud of Tuan and pray for the good things beside him forever
