　　 　　　　　　　 　　Way of Life for Students

The Internet is way of life for US college students, with research showing them to be one of the most connected groups.

A recent study by Harris Interactive and 360 Youth found that 93 percent of American college students visit the Internet, and this market is expected to grow from 15.2 million in 2003 to 16.4 million in 2007. That is slow but could be the result of the already high number of college Internet users.

About 88 percent of American college students own a computer, and more than half have broadband(宽带) connections. Furthermore, 67 percent use the cell phones and 36 percent use their mobile devices to visit the Internet. Study findings are that 42 percent go online mainly to communicate socially, and 72 percent of college students check emails at least once a day, with 66 percent using at least two email addresses.

The most popular online social activity is forwarding messages to friends of family, with 37 percent of college students saying they do so. The study also looked beyond the Internet surfing(冲浪) habits and into the buying habits of this group, and found them responsible for more than US $ 210 billion in sales last year alone.

College students have learned how to spend their money, with 93 percent saying low prices were important when shopping.

The study also showed that 65 percent make loan(贷款) payments; 41 percent of freshmen have a credit card; and 79 percent of seniors have a credit card. A significant number of charges on these credit cards are likely to be for entertainment and leisure expenses.

Accidents happen almost daily. Some accidents are minor and some are serious but others may be fatal. We read about such accidents nearly every day in the newspapers. It is wrong for people to think that accidents occur only on the roads or highways, or even at worksites. Home accidents are just as common. Because very few home accidents are reported, people tend to think that there are few accidents that happen in homes.

There have been many cases where people fall to their deaths from high-rise flats. Children often fall from staircases while coming down the stairs. Old people may slip on wet or slippery floors if they are not careful.

Nowadays there are a lot of modern electrical appliances such as rice-cookers, electric irons, and kettles which make life easy for the modern housewives. These appliances can kill if they are not used in the proper way.

Gas stoves used for cooking are also dangerous if they are not properly handled. They may cause burns or, in more serious cases, they may even cause fires.

But all such accidents can be prevented if we are careful and obey simple rules of safety. For example, it is unwise for people to try repairing their own electrical appliances if they do not know how. It is safer for them to get their faulty appliances repaired by a qualified electrician.

　　　　　　　　　　 　 Electric shock

Injuries caused by electric shock are fairly common. When a person has received an electric shock, no one should go near him/her until the current has been turned off. If a shock occurring at work or at home causes someone to lose consciousness(知觉), electrical connection must be broken before anyone tries to give help. You should either turn off the switch at the mains or, if that is not possible, push the person away with a dry piece of wood.

　　　　　　　 　　　 Treatment of shock

Look out for signs of shock. People who have been injured or who may have lost a lot of blood, or those who have had heart attacks, may be in deep shock. The signs to look for are faintness, paleness, a moist (潮湿的), sticky skin, shallow, rapid breathing and a fast but weak heartbeat.

Shock can prove fatal, and it is essential to do something to prevent its developing. The best way to treat or prevent shock is to keep the patient lying down, better with the legs higher than the head; if possible, raise the lower part of the body on a rolled-up packet or similar object. Make the patient as comfortable as possible, loosening any tight clothing, and comfort him/her because fright increases the effects of shock.
