'USA? Britain? Which country is better to study in?' We often hear such discussions. As China opens its door, it is a dream for many Chinese students to study abroad. They want to learn about the outside world.
     It's true that studying abroad can help students develop themselves. Their foreign language skills will be improved and it may be easier to find jobs.
     But there are problems that should be considered. Language is the first. Students must spend a lot of time learning another language.     
     Students must also learn to live without parents' care and deal with all kinds of things they haven't had to do before, like looking after themselves. There are reports about Chinese students abroad running into an ocean of difficulties and giving up finally. When they have to take care of themselves, it is hard for students to study well. 
     Finally, studying abroad brings a heavy burden (负担) to the family. For most Chinese parents, the cost of studying abroad is very high. But is it worth it?
     We know that there are many famous people who have achieved success through their hard work in China. Liu Xiang is a good example. Once an American teacher invited him there, but he refused. He kept training hard with his Chinese teacher. He surprised the world when he won a gold medal at the Athens Olympic Games. So when you wonder which country is better to study in, think again.

    Several Asian hospitals are doing experiments with tele-medicine. Tele-medicine is a technology that allows doctors to "see" patients without them being in the same place. This is made possible through high-speed communication networks(网络). At both ends of the line, the way of video-meeting lets them see and talk to each other. Blood pressure (血压) and body temperature are directly shown on computers.

    Tele-medicine is already in wide use in some places such as the United States and Germany. Among other uses, village doctors hold "consultations (会诊)"with far-away experts(专家). The experts can also help them during operations.

    Tele-medicine has been slow to reach Asia because of high costs besides other reasons. When things improve, this technology will develop very fast. Chinese University of Hong Kong's medical school has joined a big hospital in Beijing, and Thailand is building a tele-medicine station connecting 20 areas.

    Tele-medicine will do good to patients because doctors from different places can see them and give their medical advice. The help is quite important if the disease is an unusual one. It also helps spread medical knowledge among experts.

    As tele-medicine develops well, its costs will be lower and it will become very popular in the medical field.

    Summer vacation means long days, sleeping in or enjoying the summer sun. It is quite true for students to enjoy a rest after a long and difficult year. But more and more parents fear their kids forgetting a lot of knowledge, so they send their children to summer schools. Because summer schools have many advantages, they can help children go over the knowledge that they have learnt during the school year.

    In summer schools, students probably study in a more relaxing situation and can come up with interesting topics for discussion with their teachers. Usually, the number of. students attending summer schools is smaller, so this gives them a good chance to connect with other students and teachers better. If a student has failed a course, summer schools may help him or her. Moreover, they are building their creativity(创造力) and imagination(想象力) as well as learning social skills.

    On the other hand, summer schools bring children problems at the same time. It takes children the whole summer vacation to learn without playing. That is too long. As a result, it may make them less interested in school during the coming year.

    For many students, taking summer classes can be a tiring experience. Teachers teach the subject too quickly, where only harms the whole education of students. Summer schools are usually expensive. They usually offer only a few subjects. So many students have to take classes that they don't like.

    A summer school can be a good chance for students who need it, but it can be difficult for students who need a rest. So you can decide whether a summer school is suitable for your children.

    It is said that the eyes are "the windows of our soul". Beautiful and bright eyes not only show a good health but also make you look very attractive. However, to have healthy eyes, you have to look after them properly. Your eyes need taking good care of.

    Be careful with your diet. First, eat food that is good for your eyes. They are fresh fruits, vegetables, fish, eggs, and milk. Besides, a regular amount of vitamins A and B2 should also be taken.

    A regular and sound sleep is a must. It relaxes your eyes and gives them enough rest. Sleep not only helps repair the tired body. Usually, you must sleep for at least seven to eight hours every day. Loss of sleep can give you dark circles under the eye.

    You must exercise your eyes every day. Blink(眨眼) your eyes at regular periods, which makes the eyeballs full of water and gives them a good wash.

    We use our eyes in many wrong ways. Fox example, if a small thing goes into our eye we start rubbing it, which is wrong. Rubbing can hurt your eyes. Don't read or write in poor or bright sunlight. Always use sunglasses as sunlight can cause eye tiredness. Light should not shine directly in your eyes.

    Too much reading, watching TV or working on the computer can also cause eye tiredness.

    Remember to always take care of God's most beautiful gift to you. Your life will be very colorless without your eyes.
