We are all busy taking about and using the Internet. But how many of us know the history of the Internet?
Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer networks didn’t work well. If one computer in the network broke down, then the whole network stopped. So a new network system had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way, computer network system would keep on working all the time.
At first the Internet was only used by the government (政府). But in the early 1970s, universities, hospitals and banks were allowed to use it, too. However, computers were still very expensive and the Internet was difficult to use. By the start of the 1990s, computers became cheaper and easier to use. Scientists had also developed software that made “surfing” the Internet more convenient.
Today it is easy to get on-line and it is said millions of people use the Internet every day. Sending e-mails is more and more popular among students.
The Internet has now become one of the most important parts of people’s life.

Jessie felt her life so boring one summer day. She was tired of watching TV, she read all her books, and her friends were on vacation. She wanted something different to do. Suddenly, she saw the lawn mower(割草機) sitting in the yard.
“Mom,” she shouted, “I think I will mow the lawn.” Her mom ran into the yard and said, “Oh no, you don’t. You’re too young to mow the law.”
“I’m fourteen years old and know how to do it,” Jessie said. “Besides, it would help Dad out, and he won’t have to worry about it over the weekend.”
Mom thought for a while and then decided to let Jessie give it a try. After all, she was home and would keep an eye on her. Jessie already knew how to start the lawn mower from watching her dad. Jessie checked the gas(汽油) to make sure it was full, and put on her gardening gloves to protect her hands. Mom watched from the kitchen window. Jessie really does know how to mow the lawn. She was very careful around the flowers and trees. When she finished, she felt so good, but she was so hot. Mom brought her some ice tea and said, “You sure did a great job. Dad will be very surprised.”
Later that day, Dad came home and said to Jessie’s mom, “You didn’t have to mow the lawn. I was going to do it on Saturday. It looks great. Thanks.”
“I didn’t mow it. Jessie did.”
“Wow, our little girl is growing up!” Dad told Jessie what a great job she had done.
“It was fun, and I will do it again next week,” said Jessie.
The neighbor next door came by and asked Jessie if she wanted to mow his lawn and make some money. “Sure!” said Jessie. Jessie began mowing his lawn. Two other neighbors asked so, then another three. Jessie was now mowing lawns for them all and making some money. She was no longer bored! “I won’t have time to spend my money,” she laughed to herself.

Childhood is a time of fun and games. Many people still remember when they were young, they often played games like hide-and-seek and chess. Playing teaches children how to get along with others, and it also helps to exercise the mind and body. However, children today spent most of their playing time in front of the computer, playing video games.
A recent survey found that in the US children between 8 and 12 spent at least 13 hours a week playing video games or “gaming”. Boys of this age spend even more time, almost 16 hours a week. Although some people will say that gaming is helpful, it brings many problems as well.
One big problem is that kids who spend most of their time on games might have difficulty communicating with real people. They might have trouble sharing and resolving problems because they do not practice these shills when sitting alone at a computer.
Another problem is about health. Game players usually sit for hours without doing any exercise. And they might not eat healthily. As a result, they might be out of shape.
Next, game players might have trouble with their lessons. Many of them spend more time playing games than working on their homework. In the end, _______________.
Finally, it is always possible that the gamers become addicted(成癮). Some people play four or five hours a day or even all day. This happened to a 28-year-old Korean man. He spent about 50 hours playing an online game without sleeping or eating well. He died while gaming!
This is one example of the dangers of video gaming. It tells us that video gaming, like everything else, should not be done too much. A few hours a week should not hurt, but several hours a day just might be dangerous to your health.
小題1:Children of 8 to 12 in the US spent at least _____ hours a week playing video games.
A．13B．16C．28D．50
小題2:How many problems about playing video games are mentioned in the passage?

小題3:Which of the following is the right sentence for the blank(空白處) in Paragraph 5?
A．they might become illB．they might lose their friends
C．they might stop playing games D．they might get lower grades at school
小題4:What does the writer want to tell us by writing this passage?
A．Video gaming has quite a lot of advantages.
B．Video gaming might be a dangerous thing.
C．Childhood is a time of fun and games.

Can plants eat people? Probably not, but there are many plants that eat meat. Some of them are big. And they can eat small animals. One famous meat-eating plant is the Venus flytrap.
The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like the pages of a book. They can open and close very quickly. Inside the leaves, there are three small hairs. If a fly(蚊子) touches one of the hairs, the leaf close quickly. The fly cannot get out. In about half an hour, the leaf presses(擠壓) the fly until it is dead. Then, the plant covers the fly. Slowly, the plant eats the fly.
How can that happen? Most plants get what they need from the sun, the air, and the ground. In some places, the ground is very poor. It doesn’t have all these important things, especially nitrogen(氮). Animal meat has a lot of nitrogen, so some plants eat meat to get what they need. Let’s hope that some of the bigger plants don’t get the same idea!
小題1:What kind of plant is the Venus flytrap?
A．It is the plant that can be eaten as vegetables
B．It is the plant that can eat people

In the opinion of many people, the two­parent family is the correct way to raise children. Traditionally, this has been as the most natural way, but single­parent families have had to face prejudices(偏見) against their life­style. However, the single­parent family is the fastest growing type of family. In the United States, a national survey showed that at least 50% of children will be members of a single­parent family. So we think it is important to throw prejudices away and to see the advantages of single­parent families.
When compared to two­parent families, single­parent families are usually at a disadvantage in some ways. They are often in short of money, and children receive less attention. What’s more, single parents can find themselves under too much pressure(壓力) of both work and home. Despite(盡管) these disadvantages, it is possible for single­parent families to look for support from friends, schools, communities or other organizations. They need to remember that nobody can do it alone.
Surprisingly, single­parent families also have some advantages over two­parent families. Single parents have greater flexibility(靈活性) in spending time with children, because they don’t have to consider the needs of a husband or wife. So they can develop closer relationships with their children. Another advantage comes from the fact that single parents often work together with their children to solve problems, which makes children feel more needed and valued.
It’s important to remember that single­parent families have, until now suffered prejudices from some people. They think that it’s easier for the children in single­parent families to drop out of school in teens, and to be jobless in their early twenties. But, with the support from friends, schools and communities, single­parent families become more accepted by society, and this situation is certain to improve. In the future we will probably see these prejudices disappear.
小題1:What does the writer mainly tell us in Paragraph 1?
A. People shouldn’t have prejudices against single­parent families.
B. The single­parent family is not good for raising children.
C. The two­parent family is the correct way to raise children.
D. 50% of children will be members of a single­parent family in the USA.
小題2:Which disadvantage of single­parent families is NOT mentioned in Paragraph 2?
A．They are often in short of money.
B．Children may receive less attention.
C．Children also suffer from the prejudice.
D．Parents are under pressure of both work and home.
小題3:How can single parents make their children feel more needed and valued?
A．Don’t consider the needs of others.
B．Pay more attention to their children.
C．Develop closer relationships with their children.
D．Discuss and solve problems together with their children.
小題4:Which of the following may be the best title for this passage?
A．Advantages and Disadvantages
B．Changing Views on Single­parent Families
C．Best Life­style for Children
D．Comparing Two Types of Family
