The parents are nice, but they often ask you to watch over their child. How do you feel? What would you do if the child asked you to do his/her homework for him/her?

I work for the Li family and I look after their library. My job is to store all the books that they borrow from their school or friends in my brain. Of course my brain is as large as a mountain so work like that is no trouble to me. I really eat books just like people eat food.‎ ‎ The Lis have a child who needs me to remember all his school textbooks so I can do his homework for him. He just gives me the information on the subject, what has to be done and the page numbers and I get on with it while he enjoys himself with his friends. Sometimes I don’t think it is right to do his homework for him—it’s somewhat cheating. However, his parents are very concerned at the pressure of work in school these days. The child has too much homework to do. They like him to go to the key school but they also want him to be able to have hobbies, learn to swim and keep fit! Poor child!‎ Mr and Mrs Li work very hard too. Mr Li is an architect and designs great tall apartment blocks. Mrs Li is a doctor and has to look after many patients. I remember all the plans for Mr Li’s projects and can tell Mrs Li which drugs are the best to give any particular patient. Mrs Li no longer has to read all those medical journals because I can do it for her. She and her husband have sometime together to enjoy life too.‎ ‎ So they consider me the most important person in the family after themselves. I am always introduced to their friends and play with visiting children. I am the perfect family academic aid and, although I was not cheap to buy, Mr Li says I was worth every yuan!‎ ‎2. Homework Now computer games become more and more popular among students. Write an article on this topic to show their views.‎ One possible version:‎ ‎ Computer Games There's a famous saying, "Everything has two sides, the ad-vantages and disadvantages. " Computer games are no exception. In its development computer games have brought both advantages and disadvantages. ‎ Now, here's an example: A racecar game—— Need For Speed III is absolutely a fantastic game. Imagine this: You sit in-front of the screen with wheels in your hands and eyes fixed on the screen. You can feel the powerful roaring of the 3600ml engine from Porsche 911 Turbo as you drive up to ‎290km/h without any real danger. You can also hear the wheels screaming as a sharp turn was being made. And if you have a 3Dfx card you can really feel what is realistic. The road, the raindrops, the snowflakes and other racecars seem as real, which give us a great pleasure and satisfaction. Apart from it, they can train us to respond to things quickly. Moreover, computer games can stimulate our imagination and interest in electronics and computer sciences. On the other hand, computer games also have its disadvantages. First, it is harmful to our eyes and health, which is one of the most serious disadvantages about computer games. And sec-only, we are still middle school students, playing games is not our destination. If we play games too much, we may forget those things that we should do, because we lack the ability to control ourselves. Also, games cost a lot of money, especially for us who do not have a regular income ‎ So, what attitude shall we hold towards computer games? Of course, we can not kill games, nor could we stop them from developing, because they are required by all kinds of people. After all, playing games is a primitive type of using computer, as many of my classmates do. And I think we should not stick to them, and if you don't have the ability to control yourself, you'd better keep away from it before you really stick to it. ‎ Sample writing 2:‎ With the development of computer-technology, computers are becoming more and more popular with people all over the world. The frequency of using computer has risen year by year. The advantages taken over by computers can be seen everywhere.‎ ‎  Due to the comprehensive applications of the computer, it has been gradually taking place of human beings in some areas. Such as people can use computers to compose,to purchase gods, and to hold meetings. What's more, computer can greatly enhance people's working efficiency.‎ ‎ However, everything has its two aspects. Computer also has some disadvantages. Take some examples. Since computer games now have been more prevalent among students, they almost spend more than 6 hours for entertainment on computer, and not study any more. Next, many people now like to communicate with their friends on line, and they meet less frequent than ever before. As a result, the lack of the language speaking leads to their expression barriers. In short, we should make the best use of its good aspect to get more imperilments.‎
