People often say that the earth is like our mother. She gives life to all the living things on the earth and provides us with air, food, water and other essential things we need for living.
Once she was beautiful and rich, but now she becomes dirtier and dirtier, poorer and poorer. It is due to what we have done to her. Please have a good look at her: polluted rivers and lakes, growing deserts, the destruction of the forests and wild life, and the depletion (消耗，用盡) of the ozone layer (臭氧層)...
Can she bear to see her children putting the waste here and there? Can she bear to see her children cutting down the trees and destroying the grassland, to see the acid rain destroying everything? Can we bear to see our mother suffering (受苦) so much? Isn’t it time for us to ask ourselves whether this is the way to treat our mother?
Floods, droughts, acid rain..., these are the punishments (懲罰) from nature. Everyone should know that there is only one earth. If we go on treating her like this, it won’t be fit for us to live in any longer. It’s time for us to love her, take good care of her and cure her. We should save the earth so as to save ourselves.

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.

Three kids have been learning chemistry for only a few months. But they have already begun to challenge (挑戰(zhàn)) a world famous scientist!
Li Weichi, Huang Runling, and Xiao Yan are from Zhongshan Huaqiao Middle School in Guangdong. They have just found a red cabbage that could be a new kind of acid-base indicator (酸堿指示劑). They want it to take the place of litmus (石蕊) paper.
"We’ve learnt to think of and ask questions about life by ourselves," said Li, "We work well with each other."
British scientist Robert Boyle discovered the use of litmus paper over 300 years ago. Now it is used widely in experiments all over the world.
But when the kids did some experiments in class last winter, they saw that the litmus paper didn’t turn very blue with base matter. It’s hard to get a clear result.
Will there be a better indicator than litmus paper? The three kids decided to try and find out!
How? They went to collect over 40 plants in parks, gardens and markets. Then they ground (研磨) leaves, flowers and stems (莖) to get the pigments (色素) from them.
The kids mixed pigments with acid and base. They spent months watching carefully to see which paper showed the best colour change. They decided it was the litmus paper!
"It’s our first scientific journey, Huang said, "But it makes me want to try harder."

    Plants are very important. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals can get their food by eating plants and other animals. Man gets his food by eating plants and animals, too. So animals and man need plants to live. This is why there are so many plants around us.

On October 31st, 2009, Chinese famous scientist Qian Xuesen, died in Beijing when he was 98 years old. He is famous as “the country’s father of space technology and king of rocketry”.
Qian was born in 1911 in Hangzhou. He left for the United States after winning a schol­arship to graduate school in 1936. He studied at the Massachusetts Institute{學(xué)院) of Technology and later at the California Institute of Technology.

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 _____.

There are few families in the United States that do not have either a radio or television set. Both of them have become a necessary part of our daily life, keeping us filled with the news of the day, teaching us in many fields of interest, and making us happy with singing, dancing and acting.
Marconl, the Italian inventor, who gave us the radio, probably didn’t know how much his great invention would have done for the world in the years to come. Radio had, perhaps done as much as any other communication tool. Things of the world can be reported to people everywhere a few seconds after they happen. Travelers in or out of–the–way places, ships at sea even astronauts round the earth are able to keep in touch with each other by radio.
Television is another important invention. It lets us see as well as hear the actor. Since its appearance, TV has done a great deal in the daily life of people everywhere. Many programs are now televised in color.
Perhaps the most modern invention is “Telstar”, a “star” moving round the earth. It makes it possible for the people all over the world to be closer than ever before. Now a family in Chicago can watch on TV a motor–car race in Italy, a table tennis competition in Beijing or a volleyball match in Japan as these events are actually happening!

Drinking water is good for your health. There are some scientific ways of drinking water.
1. It is the best medicine to drink two glasses of water in the morning.
2. Drink clean water.
3. Drink the water that has not been boiled.
Many people think boiled water is safe and good to people’s health. In fact, it is not true. The boiling point of water is 100℃. By boiling it, most bacteria（細(xì)菌）in water can be killed. In the past, the water was less polluted. So boiling was a good way to make clean water. But heavy metals and other dangerous things in today’s water are much more terrible than bacteria. Boiling doesn’t fix that problem. And boiling water may give us more of the dangerous things in our glass.
4. Never use soft drinks to take the place of water.
5. Water is also needed in winter.
6. Drink water at the right time.
1) After getting up in the morning, you have less water in your body, because you weren’t drinking for the whole night. So you should drink some water to keep your health after getting up in the morning. That can prevent high blood pressure, cerebral hemorrhages（腦溢血）and so on.
2) Drinking water at about 10 am helps your body keep enough water.
3) Drinking water at about 3 pm can clean out the wastes in your body.
4) About eight o’clock in the evening is the best time to drink water. Your blood gets thicker when you sleep. Water will make your blood less thick.
