However, computers were still very expensive and yet Internet was difficult to use. By the start of the 1990s, computers became cheaper and easier to use. Scientists had also developed (开发) software (软件) that made "surfing" the Internet easier.

A PLANE crashed (坠机) in Libya on May 12, killing 103 people on board. The only survivor is a 10-year-old Dutch boy.
This is not the only example of a crash in which everyone but a child died. A 12-year-old girl was the only person to survive a 2009 air crash in the Indian Ocean. When a plane crashed over Sudan in 2003, only a 3-year-old boy survived.
It's a question that leaves safety experts puzzled. So farthere is not enoughhard evidence forthem to answer withany certainty.
Although unclear, there arereasons to suggestthat children maycope (应对) better than others.
Professor Ed Galea at the University of Greenwich, suggested children would be cocooned(被紧紧抱住) within their seat and therefore might be less probably to receive injuries.
"With an adult with their head above the seat and legs on the floor, they will receive some kind of injury landing on your head and legs," he told the BBC.
"It would be miraculous (奇迹的) to survive that, but there have been cases(情况) of people falling into trees. A smaller body would mean it's more possible the tree would break your fall," he explained.
Studies found other factors (因素), besides luck, influence the chances of surviving a crash.
One is seating. A study of plane crashed conducted by Poplar Mechanics found that people sitting toward the back of the plane were more probably to survive than those sitting toward the front. A survey conducted by researchers at the University of Greenwich in the UK found that what matters most is how close you are to an exit(出口). Sit in five rows(排) of an exit, and you've got better-than-even chances of surviving. Sit in six rows or more away, and your chances are less than 50-50.
Other factors for surviving a plane crash include wearing a seat belt, paying attention to flight instructions and staying alert(警觉) during taking off and landing. And of course, don't fly with airlines that are the most pobably to crash.

Last March, the H7N9 virus (病毒) hit Shanghai, Anhui, Jiangsu, Zhejiang and so on. It seemed that most people who were infected(被感染) with H7N9 had the common flu. Some people suffered from a fever or a cough.

Don’t be afraid—it’s not easy to be infected with the virus. Here is some advice to help you protect yourself when it comes.
Wash your hands. You need to wash your hands with soap and hot water before you eat, after you use the toilet, and after you touch animals, because your hands may carry viruses.
Cover your nose and mouth. When someone sneezes(打喷嚏) or coughs, flu viruses can travel as far as one meter through the air, so you’d better stand a proper distance (距离) while talking to someone who has a cold. And always cover your mouth and nose with a piece of paper when you sneeze or cough, and then clean your hands.
Wear a mask(口罩). Some doctors say that masks can stop the flu as much as 80%, but if
you don’t wash your hands often, it’s no use wearing a mask. And it’s necessary to wear the mask in the groups of people.
Do sports often. Exercises will help make your body strong enough to resist the virus.
小题1:When did the H7N9 virus hit Shanghai?
A．In March, 2013. B．In May, 2013.    C．In March, 2012.

Space vegetables are grown from seeds (种子) that have been taken to space and brought back to the earth. The seeds are affected by the radiation (辐射) and low gravity in space. When they are brought back to the earth, these seeds produce vegetables that are bigger and healthier than normal vegetables. However, some people worry about eating space vegetables. They think that space vegetables might not be good for us and could make us get sick because of the radiation in space. However, people should not be frightened because space vegetables are very healthy.
Here are some facts that you should know about space vegetables.
Space vegetables are grown from seeds that are carefully chosen. When seeds are brought back from space, they are tested to make sure that they will be safe to eat.
Space vegetables are better for you than normal vegetables. For example, space tomatoes stay fresh for twenty days, which is one week longer than normal tomatoes.

For example, if nut genes (坚果基因) are put inside potatoes, people allergic (过敏的) to nuts might get sick from eating these potatoes because they do not know they are also eating nuts.
