Should the University Campus be Open to Tourists?1).校园是否应对游客开放,人们看法不同,说明你的观点; 2).阐述你的理由。

参考范文:

With the development of tourism, the campuses of many famous universities in China are open to the tourists. People have different opinions about it. Some people think that the tourists’ visit to the campus will make it harder for students to study. Worse still, it may cause some safety problems. However, others think that it can bring students and the society closer and is good for cultural exchange between people. In my opinion, several factors should be considered before opening the campuses to tourists. First, I suggest we should choose the universities with long history and beautiful campuses. Second, the campus should only be open to tourists on weekends or during holidays.

When you use a computer, the window should be on your left or your right. If it is behind you, the light will reflect on (反射) the screen. If the window is in front of you, the sun and the screen will both shine into your eyes.

Your hands and wrists

Hand and wrist injuries can happen because the hands and wrists are moved in the same way hundreds of times. If you use a keyboard for a long time,follow these three rules:1) Rest your wrists on some thing. 2) Keep your elbows (肘) at the same height as the keyboard. 3) Stop sometimes and exercise your hands,wrists and fingers in a different way.

Your back

Some people sit for many hours in front of a computer. If you sit in the wrong way,you can injure your back or your neck. So you should sit with your back straight. The top part of the screen should be in front of your eyes. Your forearms,wrists,hands and the upper part of your legs should all be parallel (平行) to the floor. If you are sitting for a long time,get up every 30 minutes and exercise your arms,legs and neck.

Enjoy your computer,but use it safely.
