| People in different countries have different ways of doing things. Something that is polite in one country may be quite impolite in another. In Britain, you mustn't lift your bowl to your mouth when you are having some liquid (液体) food. But it's different in China. And in Japan you even needn't worry about making much noise when you have in. It shows that you are enjoying it. But it is considered as bad manners in Britain. If you are a visitor in Mongolia, what manners do they wish you to have？ They wish you to give a loud "burp" (打嗝) after you finish eating. Burping shows that you like the food. In Britain, you should try not to put your hands on the table when you're having a meal. In Mexico, however, guests are expected to keep their hands on the table during a meal. But in Arab countries you must be very careful with your hands. You mustn't eat with your left hand. Arabs consider it very bad manners eating with left hands. So, what should you do if you are on a visit to another country？ Well, remember when in Rome do as the Romans do. You can ask the local people to help you or just watch carefully and follow them. |

第10题
First the person must recognize that there is a problem. For example, Sam’s bicycle is broken, and he cannot read it to class as he usually does. Sam must see that there is a problem with his bicycle.
Next the thinker must define the problem. Before Sam can repair his bicycle, he must find out the reason why it does not work. For instance, he must determine if the problem is with the gears, the brakes, or the frame. He must make his problem more specific.
Now the person must look for information that will make the problem clearer and lead to possible solutions. For instance, suppose Sam decided that his bike does not work because there is something wrong with the gear wheels. At this time, he can look in his bicycle repair book and read about gears. He can talk to his friends at the bike shop. He can look at his gears carefully.
After studying the problem, the person should have several suggestions for a possible solution. Take Sam as an illustration. His suggestions might be: put oil on the gear wheels; buy new gear wheels and replace the old ones; tighten or loosen the gear wheels.
Eventually one suggestion seems to be the solution to the problem. Sometimes the final idea comes very suddenly because the thinker suddenly sees something new or sees something in a new way. Sam, for example, suddenly sees that there is a piece of chewing gum between the gear wheels. He immediately realizes the solution to his problem: he must clean the gear wheels.
Finally the solution is tested. Sam cleans the gear wheels and finds that afterwards his bicycle works perfectly. In short, he has solved the problem.
