寧波市2012中考英語模擬試題及答案

B
　　Computers can injure you. Most other injuries happen suddenly. For example, if you fall off a bike and break your arms, it happens very quickly. But computer injuries slowly.
　　You probably know how to ride a bike safely. Now learn to use a computer safely.
　　Your eyes
　　Too much light can injure your eyes, so never sit too close to a computer screen. Your eyes should be at least 50 centimeters from the screen. Remember to look away from it sometimes. This gives your eyes a rest.
　　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 (手腕)
　　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 something. 2) Keep your elbows at the same height as the keyboard. 3) Stop something 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 all 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 necks.

　　Chinese government has decided to give up the rules of food with no checking
　　According to the Xinhua News, from September 17 2008, Chinese government decided to give up the rules of food with no checking. Many people said yes to it. The officer said that these days, the food safety accident about children milk of Sanlu made the government decide to give it up. In order to keep the food safe and people healthy, Chinese government said that all the food must be checked. The rule of food with no checking made in 1999 was given up from that day.
　　“I think if the companies get the food with no checking, they will never check their food. It gives them the chance of making the food of poor quality,” an old man said in the shop. “ I hope our government not only gives it up, but also makes some strong rules to manage the companies,” a young woman told us. “ The important point is our government should send officers to the companies and check their food every time,” a shop owner said. A young expert of food safety said, “ The department of government should take the food from the shop or supermarket and check, not ask them to send. In that way, we can get the real checking.”
　　But in order to keep people’s health, the government asks the officers to check all the food before they are sent to the shop or supermarket. That means all the food must be checked before they are sold.
