The computer is a wonderful machine. They are already widely used in industries and in universities. They are used in many ways.
Computers can do many kinds of work. For example, computers can helps us do maths problems quickly. Some problems are too hard for us to work them out, but computers can. A scientist can ask computers some questions, and the computers can answer on the screen.
In a car-factory computer tells the robots how to do with the cars.
Computers are very useful. So many parents buy computers for their children. They hope computers can help them improve their studies in school, but some children don’t do as what parents want them to do. Because they used the computers for surfing on the Internet and spend too much time playing computer games instead of learning. It does not good for their eyesight. So their parents complain about computers not help children to study but also make them fall behind.
In many companies computers instead of workers to work. So many people lose their jobs. So many workers think computers bring them a lot of trouble.
If computers are good for us or bad for us it’s hard to say so I hope computers will be used in the right way.
The air we breathe is so freely available that we take it for granted. Yet without it we could not survive more than a few minutes. For the most part, the same air is available to everyone, and everyone needs it. Some people use the air to sustain them while they sit around and feel sorry for themselves. Others breathe in the air and use the energy it provides to make a magnificent life for themselves.
Opportunity is the same way. It is everywhere. Opportunity is so freely available that we take it for granted. Yet opportunity alone is not enough to create success. Opportunity must be seized and acted upon in order to have value. So many people are so anxious to "get in" on a "ground floor opportunity", as if the opportunity will do all the work. That's impossible.
Just as you need air to breathe, you need opportunity to succeed. It takes more than just breathing in the fresh air of opportunity, however. You must make use of that opportunity. That's not up to the opportunity. That's up to you. It doesn't matter what "floor" the opportunity is on. What matters is what you do with it.
Air is around us. We can not see it, smell it, or taste it. But we can feel the wind blow. We can see the wind move waves on the water, clouds in the sky, and tree branches. Wind is moving air.
Without air we could not breathe. There could be no living plants or animals. Because sound travels through air, without air there would be silence. The movement of air can support a large, heavy plane.
Air is a mixture of gases and water vapor. The most important gases in the air are nitrogen and oxygen. 78 percent of the air is made up of nitrogen, and about 21 percent of oxygen. Almost all living things use the oxygen in air. Fire cannot burn without oxygen.
Since the one child policy carried on, many families had only one kid. As the children growing up, they felt lonely, because they did not have anyone to accompany. They felt so envious when they saw others have siblings. There is no doubt that the one child policy has controlled the population to increase so fast and helped people to improve their life lever. Recently, the government tends to open the second child policy slowly. People hold the different opinion. Some people think that it is good to let the child have siblings, so they will not lonely and can learn the meaning of sharing. Other people don’t want to have one more child because they don’t have enough money. They want to give the best education to the child, so they think one child is enough. Anyway, the second child policy gives people more choice.
This summer holiday, I had travelled to Hong Kong with many other students. We went to Hong Kong by plane. Hong Kong is very small, but there are many people living there.
In Hong Kong, all of the buildings are very tall. There are lots of shops there and you can go shopping until about 11:00 at night. In Hong Kong, things are very expensive, so we only bought a few souvenirs.
We went to lots of places, such as the Avenue of Stars and Ocean Park. I like Ocean Park best. The park is very big. Sitting in the cable car, you can see two hills, lots of different flowers and the sea. Some students were afraid of sitting in the cable car!
We stayed in the Shu Ren College. There are many big trees around it. We had meals in the restaurants, but I didn't like the food.
Hong Kong is very beautiful. I like Hong Kong and I hope to go there again some day.
Environmental problems are becoming more and more serious all over the world. For example, cars have made the air unhealthy for people to breathe and poisonous gas is given off by factories. Trees on the hills have been cut down and waste water is being poured continuously into rivers.Furthermore, wherever we go today, we can find rubbish carelessly disposed. Pollution is, in fact, threatening our existence.
The earth is our home and we have the duty to take care of it for ourselves and for our later generations. Fortunately, more and more people have realized these problems. Measures have been taken to cope with these problems by the government. Laws have been passed to stop pollution. I hope the problem will be solved in the near future and our home will become better and better.
Environmental problems are becoming more and more serious all over the world. With the development of industry and agriculture, cars make GREat noises and give off poisonous gas. Trees on the hills have been cut down,and waste water is being poured continuously into rivers. Furthermore,wherever we go today, we can find rubbish carelessly disposed. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even poses a great threat to man's existence.
We must face the situation that exists and take actions to solve our environmental problems. For instance, new laws must be passed to place strict control over industrial pollution, the pub!ic must receive the education about the hazard of pollution and so on. We hope that all these measures will be effective and bring back a healthful environment.
When I got settled, the total use of the microwave to do their own things to eat. One day, my father saw me, I am afraid to say that I grew up as a cook. I immediately shaken like a rattle-drum head, you said : "That is not my ideal. When I grow up I want to IT (information technology) industries. "Yes, I bought a computer five years ago after his father, I am familiar with it day by day. Until last year, and I have formed a deep bond with it. From then on, I want success in the information technology industry to make contributions to the cause of national computer. But my father said I could only do in the field "testing the game," is what the new game, and always let me play with, the report there will be any games. I think what he said is not their fault, I always play games recently, those who do not have a veteran like Flash. In recent days, I sprouted out of a bad idea : I will be playing the game that the network server to the black. My account will revise the highest level. However, I Xiangliaoyouxiang, this is wrong, but was caught by the police network is not good. When hackers but also need high computer skills. As a member of the IT industry is my ideal, I would like to advance this goal, to improve their computer skills
