Different from popular thought, colds are not caused by bad weather. Colds are caused by viruses(病毒)in the body, and you are better out on the snowy day than you are in a warm room, with your friends, who may be passing the virus around. If you feel a chill when you are coming down with a cold, you are already sick. A chill is an early sigh (标志)of the cold.
The virus can spread(传播)through air when a cold-sufferer(患者)coughs or sneeze surprisingly, this is not the most usual way of spreading. Many studies have now shown that most colds are caught by hands. A cold sufferer rubs her nose, so spreading the virus to her hand. Then a friend comes to visit her. They shake hands. The friend then get something to eat by hand, and several days later she catches a cold. Although some parents pick up their children's tissues(纸巾)and carefully throw them away, they failed to wash their hands. They'll catch the colds, too.
Cold virus can also be spread by objects, for example, telephones plates. The cold-sufferer as well as other members of the house, by washing their hands often, will stop the virus from spreading in a way.

It is important that you make yourself excited to make your memory more active. You can do this by doing some new activities and by changing your daily habits. Learning a new skill helps your brain to develop. When trying to remember something, you should pay special attention to the most important things about it. Do not allow other thoughts to enter your mind because they will reduce your chances of making right memories.
An excellent way to help improve memory is to connect information with pictures. Try to see the pictures in your mind. Taking notes and keeping a diary will also be helpful.
Healthy food and plenty of vitamins are necessary for your memory to work well. Drinking a lot of water also helps keep your memory. You must allow your brain to have enough sleep and rest. When you are sleeping, your brain stores memories. Not enough sleep can cause problems with storing information. And being tired will also stop you from being able to think clearly and well.
In order to keep your mind on your work, you must be free from worry. Generally keeping fit and normal health checks are both important—not just for improving your memory.
