We live on Earth. It's our home. But how much do you know about it? Let me tell you something about our Earth.
The Earth is like a huge ball. Like the other seven planets, the Earth is running around the sun. It's the third nearest one to the sun. It takes the Earth about 365 days to run around the sun. At the same time, the Earth is going around itself. If you are in space, you can see lots of white clouds over the surface of the Earth. Through the clouds, you can see the blue colour of the oceans, and the brown colour of the land. About 70% of the Earth is covered with water.
Why do we have day and night? When the half of the Earth is facing the sun, it's daytime. As the Earth turns, and this half is away from the sun, night is coming. And it's daytime for the other half.

Amanda is an American filmmaker and actress. She came to China three years ago to study Performance at Beijing Film Academy. Last month, she mto Japan to study Economics at the University of Tokyo. On June 10th, she r
to the USA. She chatted with her parents about the cultural d
between the two countries.
“The people in bcountries are very friendly to f
. But they have different cultures. For example, when I spoke Chinese in China, the people there always showed s
on their faces. But when I came to Japan, I found it was o
. Most local people there hoped I could talk with them in Japanese, t
I was not good at it,” she said.
Amanda thought this might have something to dwith the fact that the western group in Japan is o
than the one in China. They have stayed in Japan for a long time. And most of them speak Japanese well. But Westerners in China are still quite a new group. They’re usually treated as guests and tourists.
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. How many dangers of using social networks are mentioned in the passage?
| A．2. | B．3. | C．4. | D．5. |
The writer takes MySpace as an example to show that ________.
| A．students could be put into unreal situations on the Internet |
| B．teenagers are facing unknown dangers on the social networks |
| C．Internet provides more social websites to American teenagers |
| D．social networks are very popular among teenagers in America |
We can infer from the passage that ________.
| A．the dangers are similar when chatting online and surfing social networks |
| B．more than half American teenagers aged from 12 to 17 use social networks |
| C．teens who ask for help are wiser when meeting problems on social networks |
| D．there are more disadvantages than advantages for teens to use social networks |

Three kids have been learning chemistry for only a few months. But they have already begun to challenge (挑战) 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 (酸碱指示剂). 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 (茎) 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 color change. They decided it was the litmus paper!
"It's our first scientific journey, Huang said, "But it makes me want to try harder."Whom did the three kids want to challenge?
| A．Their chemistry teacher. |
| B．Their headmaster. |
| C．Robert Boyle |
| D．Thomas Edison |
From the text, a red cabbage is a kind of ____.
| A．plant | B．animal | C．paper | D．liquid |
What is widely used as the acid-base indicator now?
| A．red cabbage | B．litmus paper |
| C．any plant | D．any flower |
