We are often asked to make a speech in life. Most of us are afraid of it and don't do a good job. Here are some simple steps to make your speech a successful one. First of all, find out everything you can about your subject and at the same time find out as much as you can about your audience. Who are they? What do they know about your subject? Put yourself in their shoes as you prepare your speech. Then try to arrange your material so that your speech is clear and easy to follow. Use as many examples as possible. Never forget your audience. Don't talk over their heads or talk down to them. When you are giving your speech, speak slowly and clearly, look at your audience and pause for a few seconds from time to time to give your audience chances to think over what you've said. Just remember: be prepared, know your subject and your audience, say what you have to say and be yourself so that your ideas will bring you and your audience together.

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 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." 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 |
The story mainly tells us ____.
| A．how to make litmus paper | B．about the three kids’ spirit |
