5 . A teenager needs to have a sense of independence in their life to feel secure (安全的). To some teenagers independence means a lot to them, and I think that some parents don’t allow their teenagers enough independence.

Independence has something to do with freedom. Some kids are not allowed to go anywhere alone, and the only thing their schedule includes is going to school, coming home, going to sleep, and repeating the process the next day. Parents tend to be afraid that their kids can get hurt if they go outside into the world. But if parents control their kids too much, they may never learn to live on their own. The best way for a teenager to learn lesson is through experience. I think it is beneficial for teenagers to have freedom.

Teenagers’ lack of freedom can also stop them from having good friendship at school. Some might say this is a good thing, because it helps them focus more on their school work. I argue that this can only discourage them not to do their school work. Some parents do not allow their children to be around their friends outside the school, thinking that this will get them into trouble. But I don’t think so. Instead, isn’t this a good reason for parents to get their children a cellphone? Cellphones allow teenagers to stay in touch with their parents, and communicate with friends.

Privacy is another issue between parents and their teenagers. Teenagers tend to enjoy relaxation by themselves in their own room. This also gives them a sense of independence. It often annoys teenagers when their parents enter their room when they are not home. I know that my mom always goes in my room when I’m not home, and this has brought me to the point where I have asked many times to get a lock on my door.

The United Kingdom, Great Britain, Britain, England--many people are confused by     1     these different names mean. Getting to know a little bit about British history will help you     2    (solution) this puzzle. In the 16th century, the nearby country of Wales was joined to the Kingdom of England. Later, Scotland and the Kingdom of Ireland     3    (add ) to create the United Kingdom of Great Britain and Ireland. Finally, the southern part of Ireland broke away from the UK, which resulted     4     the full name we have today.   As a matter of fact, the four countries     5     belong to the United Kingdom work together in some areas.

If you keep your eyes open, you will be surprised     10     (find) that you can see both its past and its present.

10 . We are all busy talking 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, 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 had become cheaper and easier to use. Scientists had also developed software that made “surfing” the Internet more convenient. (方便的)

Today it is easy to get online and it is said that millions of people use the Internet every day. Sending email is more and more popular among students. The Internet has now become one of the most important parts of people’s life.
