Recent research from the Pew Internet Project suggests that 90% of Americans aged from 12 to 17 use the Internet, and 51% of those teens use social networks. However, there are many possible problems with social networking sites and the teenagers who use them.
Apart from the social advantages, social networking sites can be used to record school research, develop artistic talents and experiment with other forms of subject creation. They provide a way to communicate with others who share the same interests and to get helpful advice on ongoing projects.
Along with these advantages come some dangers. For example, most social networking sites are open to all, especially MySpace, which is the most popular social network among teens in America. It means that they could be put in unpleasant and frightening situations.
A greater danger is that teens may become objects of the people with secret purposes. The secrecy of some social networking sites makes it easy for dangerous people to find young teens and invite them into dangerous conversations. It’s easy for them to pretend as teens and draw children into dangerous real-world communication as well. Then further hurt might be on its way.
Another danger is identity stealing, which can happen when teens share too much information about their names, dates of birth and locations.
Therefore, it’s very important to make sure teens are safe when they use social networks.
Many of the same rules that work for online chat work for these sites:
※Don’t use your real name.
※ Don’t give out personal information to people you don’t know. A last name and a town
are enough for a bad guy to find where you are.
※ Don’t believe that people are who they say to be.
※ Immediately end any communication that makes you uncomfortable and report it to a
parent.
Only if you are sure of your safety, can you enjoy the fun brought by social networking. Besides, trying to deal with all problems on your own can lead to terrible results. Remember, asking your parents or school officials for help doesn’t mean you are unable to do anything but wiser than many others.

The Earth gives us a lot of things. We also give the Earth a lot, but some of the things are not good.
In nature, when something dies, other animals and plants get food from it. Every animal or plant gives food for other animals or plants.

So what can we do? Don’t leave any rubbish in the countryside! Don’t make so much rubbish!

What is color? Why do some of the things around us look red, some green, others blue?
Colors are really made by deflected (反射) light. We see color because most of the things reflect light. In the same way, if something is green, it reflects most of the green light. If something reflects all light, it is white. If it doesn’t reflect any light, it is black.
Some of the light is reflected and some is taken in (吸引) and turned into (變成) heat (熱能).The darker the color is, the less light is reflected, the more light is taken in. So dark-colored clothes are warmer in the sun than light-colored clothes.
【小題1】When something reflects light, we can _____.
A.see its color | B.see its heat | C.not see its color | D.see nothing |
A.some light | B.no light | C.a(chǎn)ll light | D.most light |
A.more light | B.less light | C.more color | D.less color |
A.dark-colored clothes | B.red-colored clothes |
C.green-colored clothes | D.light-colored clothes |
A.Dark color | B.Color | C.Heat | D.Clothes |

Climate is the average weather usually taken over a 30-year time period for a particular region and time period. Climate is not the same as weather, but rather, it is the average pattern of weather for a particular region. Weather describes the short-term state of the atmosphere (大氣).
The climate is changing. Many agreed that climate change may be one of the greatest threats (威脅) facing the planet. Recent years show increasing temperatures in various regions, and/or increasing extremities (極端性) in weather patterns.
Is the Earth getting warmer? Yes! The Earth has warmed by about 1°F over the past 100 years. But why? Well, scientists are not exactly sure. The Earth could be getting warmer on its own, but many of the world’s leading climate scientists think that things people do are helping to make the Earth warmer.
Global Warming may be a big problem, but can you make a difference? Yes! There are several little things you can do to make a difference. Try carpooling. This will help reduce the amount of fossil fuels going into the atmosphere. Whenever you use electricity, you help put greenhouse gases into the air. Turn off lights, the television, and the computer when you are through with them. Also, planting trees is fun and a great way to reduce greenhouse gases. Trees absorb carbon dioxide, a greenhouse gas, from the air. Finally, don’t forget about recycling.

The scientists from the Lockheed Space Company (公司) work in Felton, California, with the help of a computer. But the computer is placed in Sunnyside, about 80 kilometers away. What the scientists input is sent by telephone lines to the computer, and after a time, copies of the designs are needed back in Felton as possible. Lockheed people have tried several ways of sending the prints (印刷品), but the most effective seems to be by pigeon (鴿子). Are pigeons really used to carry messages in these days?
