Weather has a strong effect(影响) on people. It influences health, intelligence (智力) and feelings. In August, it is very hot and wet in the southern part of the United States. People there easily have heart trouble and other kinds of health problems during this month. In the Northeast and the Middle West, it is hot at some times and very cold at other times. People in those states will have heart trouble after the weather changes in February or March.
      The weather can also influence intelligence. For example, in a 1983 study by scientists, the IQ scores of some college students were very high during storm, but after the storm, their scores were low. Storms can increase intelligence. Very hot weather, on the other hand, can decrease(减少) it. Students in many schools of the United States often do badly in exams in the hot months of the year(July and August).
      Weather also has a strong effect on people's feeling. Winter may be a bad time for thin people. They usually feel cold during these months. They might feel depressed during cold weather. In hot summer weather, on the other hand, fat people may feel unhappy. At about 65F, people become stronger.
      Low air pressure(气压) makes people feel free, but it also increases forgetful- ness. People leave more bags and umbrellas on buses and in stores on low pressure days. There is a“perfect weather”for work and health. People feel best at a tempera- ture of about 64F with 65 percent humidity(湿度).
      Are you feeling sick, sad, tired, forgetful, or very intelligent today? The weather may be the reason.

        Have you ever dreamed about sending a letter to yourself or your friends in the future? While express mail(快递) is a fast way to send your letters, there is another type of mail appearing in China as a new business—future mail.

     “The letter should be sent next Mother's Day and not a day earlier!” Lin Xiaofan, acollege student in Shanghai, tells one of the companies offering the service.

Lin Xiao fan wrote the letter to her mother nearly a year earlier to express her love to hermother for next Mother's Day.

“Offering thisservice makes people slow down and lets them understand the meaning of ‘time'in another way,” said Zheng Zhimin, manager at a “future mail” company. Zheng thinks “future mail” letters help remind us of care, friendship and love.

      While “futuremail” is becoming more and more popular, some people are wondering what will happen if the postal address changes or if the company goes broken before theletters arrive.

     Zheng said customers are glad to sign a contract(签订合同) to make sure that they canbe compensated if their letters are lost or damaged.

    Most of the customers are college students and young white-collar(白领) workers. Psychologists (心理学家) said that young Chinese might have a new way to express their feelings through this service. Most peopleput their hopes and wishes in the letter so that they can experience the connection(联系) between the past and the present when they receive theletter.

    Many scientists find that colors can change people's feelings. It's very interesting. Some colors can make people feel relaxed, and some colors can make people feel nervous. Now, this kind of knowledge is being used in many places. For example, school walls are always painted green because green makes students feel relaxed. It is also good for the students' eyes. Some books are also green or light blue for the same reason. Restaurant owners not only have to know how to make food, but also have to know how to make money. Here are some things they've learned from scientific studies. The color red makes people hungry. Many fast food restaurants have red furniture or walls. Soft colors like pink and light blue make people feel relaxed, so they spend more time eating. Loud music may be nice at first, but it soon makes people want to leave. Hard seats also make customers want to eat quickly and leave. Many restaurants, especially fast food restaurants, use this knowledge to make customers eat faster.

    Get a lot of letters at this time of year from people complaining (抱怨) that they have a cold and that it won't go away. There are so many ways to cure (治愈) a child. It is often difficult to know what to do. Although (尽管) cold are rarely (很少) dangerous, weak people , such as the elderly or young babies, often catch them. Colds are always uncomfortable and sometimes very unpleasant. Of course, you can buy lots of medicine. This will help to make your cold less unpleasant, but you must remember that nothing can actually cure a cold or make it go away quickly.

    Another thing is that any medicine can be dangerous if you are already taking another type of medicine for some other illness. So always check with your chemist (药剂师) or doctor to see if they are all right for you. Also, remember that they might make you sleepy; please don't try to drive it they do! Lastly, if you want to keep away from colds, don't blindly (盲目地) believe in 'magic' foods or drinks. The best way is to keep strong and healthy –you'll have less chance of catching a cold, and if you do, it shouldn't be so bad!

    It's hard to make friends if you stay at home all the time, so get out of the house and do things that will put you in touch with(接触)other people. It's easier to make friends with them when you find you like the same things as other people.

Don't be afraid to show people what you're really good at. You can talk about the things you like and do best. People will be interested in you if they, hear something interesting about you.

    Look at people in your eyes when you talk to them. That way, they'll find it easier to talk to you, or people may think you're not interested in them and may stop being interested in you.

    Be a good listener. Let people talk about themselves before talking about "me, me, me” You can ask people lots of questions and show that you are interested in their answers.

    Try to make friends with the kind of people you really like, respect(尊敬)and admire(羡慕). You shouldn't just make friends with those people you will meet them easily. Try to be friendly with all kinds of people. That way, you'll have a bigger group of people to choose from. Then you'll be easier to make friends with other people.
