As we all know, border(边界) safety is very important to a country. In China, many common people, besides soldiers(军人), are doing what they can to keep the border safe, Wei Deyou is one of them.

    1     In 1964, Wei, a soldier in the army, went to Xinjiang to keep the border safe. Years later, when the other members left for other places, he chose to stay.     2     He worked as a border keeper while keeping some sheep to support his family. Every day, he rode a horse or walked along the border. He took everything about border safety seriously.     3     当他发现任何不同寻常的事情，他会及时打电话给警察局。 It was really hard work.

One cold winter day in 1987, when Wei was on his way home from work, a heavy snowstorm came. He lost his way and walked for several hours. He nearly lost his life. Luckily, some soldiers saved him. Another day in 1992, his 400 sheep were driven away or killed.     4     He knew some people hated him because of his strictness.

Wei has been working in Xinjiang for over 50 years.     5     无论他过着怎样艰辛的生活,他从不放弃。 These years, he has walked about 200,000 kilometers along the border. He has also found many new ways to keep the border safer. For his excellent work, he has been given some prizes. He is a model for all of us. Now he is 77 years old. He still keeps working there. Just as he said, “It's my duty to do the job. Border safety is the most important.”

I am worried about China’s car problems. More cars are now available, and     1     我们道路上的车子比以前更多了。There will be 140 million cars on our roads by the year 2020. That’s almost seven times the number of cars on our roads now. The increase in the number of new cars has already blocked roads.     2     Pollution is already a major problem and it will get much worse.     3     The sky is often a yellow-brown color in big cities. There are more road accidents in China than other countries.    4     Traffic problems and road accidents will get much worse in the future.

Cars can be very useful, but they also cause a lot of damage.     5    我认为人们在买车前有必要三思而后行。I also think more should be done about our country’s car problems.

Human activities that have indirect effects on animals can be just as harmful.     1     当我们修建农场和工厂时, we destroy animal habitats and leave many animals with nowhere to live,     2     或者没有食物可吃.     3     We can also put animals in danger without ever entering their habitats. Air, water, noise and light pollution can all have a deep and damaging influence quite far from their source. Partly due to pollution caused by ship traffic and other human activities,     4     the dolphin population has dropped greatly. As the human population continues to grow,     5     so does the effect we have on animals.

There are a number of reasons that can be given as to why children should be taught swimming at a young age.     1     如果你的孩子知道基本的游泳技巧,you can be at peace when your children are near the water.     2     The best way to teach your children to swim is to make them join swimming classes. There are professional（专业的）trainers around your children.     3     They can teach them all the skills of swimming. You can join the parent-child lessons to make your children feel comfortable. If your children are a bit older, then get permission and sit by the pool to watch them learn.

    4    游泳是一种快乐且让人放松的运动方式.You can make it easy for your children to understand. Coordinating（协调）the movements of their arms and legs will take some time. But, with regular practice and training this can be overcome. So, start with the basics and be around your children when they are learning how to swim.     5     Once they know how to swim, then you can be at peace when they play around the water.

I read your magazine every month.     1     我自己也是一个青少年, and have some problems at home that I hope you can help me with.     2     The main problem is that I can't get along with my father. Whenever I want to do something or suggest an idea, such as a restaurant we can go to for dinner, he doesn't listen to me. Then, when I refuse to listen to him, he shouts at me angrily.     3     He and my mother always make me do things I don't like, such as playing the piano and doing housework. Then, whenever I have some spare time and want to be alone, they call me selfish and distant!     4     如果我放外国音乐，我父亲很烦。Also, every time I watch a DVD: he sends me to bed or tells me to spend more time studying. He even forbids me from chatting with my friends in the Internet cafe!     5     I love him a lot, but I don't understand why he is so hard on me and will not respect the things I want to do. He was once a teenager—he should understand me better than he does.
