单选题It is reported that over 300 million people in China are suffering from nearsightedness (近视). As more children have got eye trouble, their parents hope to cure the disease by medicine, equip-ment or by correcting the way children read and sit. But in fact the care given to one"s eyes should start with the exercise on one"s feet. Three methods on how to protect eyes are as follows: Firstly, don"t fasten your shoes too tightly. Try wearing loose socks or walking barefooted at home. When traveling, try wearing cloth shoes so as to make blood circulation (循环) easier. Secondly, walking on tiptoes will help improve one"s eyesight, and prevent nearsightedness. Figures show that few ballet (芭蕾舞) performers are nearsighted. Thirdly, rope skipping also does good to one"s eyesight. When skipping the rope, one has to react quickly, which excites the brain as well as the eyes. It will also help make one grow taller. Besides foot exercises, it is good to pull one"s ears. Pulling the ears 20 times is found to be an effective way to reduce the pressure on one"s eyes soon.

单选题{{B}}B{{/B}} The Internet has opened up a whole new on-line world for us to meet, chat and go where we've never been before. But just as in face-to-face communication, there are some basic rules of behavior that should be followed when online. The basic rule is simple: treat others in the same way you would want to be treated. Imagine how you'd feel if you were in the other person's shoes. For anything you're about to send: ask yourself, "Would I say this to the person's face?" If the answer is no, rewrite and reread. Repeat the process till you feel sure that you'd feel comfortable saying the words to the person's face. If someone in the chat room is rude to you, your instinct is to fire back in the same manner. But try not to do so. You should either ignore the person, or use your chat software to block their messages. If it was caused by a disagreement with another member, try to fix the situation by politely discussing it. Remember to respect the beliefs and opinions of others in the chat room. Everyone was new to the network once. Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate. When someone makes a mistake whether it's a stupid question or an unnecessarily long answer be kind about it. If it's a small mistake, you may not need to say anything. Even if you feel strongly about, think twice before saying anything. Having good manners yourself doesn't give you license to correct everyone else. If you decide to tell someone about a mistake, point it out politely. At the same time, if you find you are wrong, be sure to correct yourself and apologize to those that you have offended. It is not polite to ask others, personal questions such as their age, sex, and marital status. Unless you know the person very well, and you are both comfortable with sharing personal information, don't ask such questions.
