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.
1.How many dangers of using social networks are mentioned in the passage?
A. 2. B. 3. C. 4. D. 5.
2.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
3.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

Play is the basic business of childhood, and in recent years research has shown the great importance of play in the development of a human being. From earliest infancy（婴儿）, every child needs opportunity and right materials for play, and the main tools of play are toys. The main function of toys is to suggest, encourage and play. To succeed in this, they must be good toys, which children will play with often, and will come back again and again. Therefore, it is important to choose suitable toys for different stages of a child’s development.
In recent years, research on baby development has shown that the standard a child is likely to reach, within the range of his inherited（遗传的）abilities, is largely determined in the first three years of his life. So a baby’s ability to benefit from the right play materials should not be underestimated. A baby who is encouraged, talked to and shown things and played with, has the best chance of growing up successfully.
In the next stage, from three to five years old, curiosity knows no bounds. Every type of suitable toys should be made available to the child, for trying out, experimenting and learning, for discovering his own particular ability: Bricks and jigsaws（七巧板）and construction toys; painting, scribbling（涂鸦）and making things; sand and water play; toys for imaginative and pretending play—the first social games for learning to play and get on with others.
But at the third stage of play development—from five to seven or eight years old— the child is at school. But for a few more years play is still the best way of learning, at home or at school．It is easier to see which type of toys the child most enjoys.
Until the age of seven or eight, play and work mean much the same to a child．But once reading has been mastered, then books become the main source of learning. Toys are still interesting and valuable, which lead up to new hobbies, but their significance has changed to a child of nine or ten years old, toys and games mean, as to adults, relaxation and fun.
1. What does the writer want to tell us in the first paragraph?
A.    Children should choose toys by themselves.
B.    Children like playing, but they don’t need any toys.
C.    Children should be given different toys as they grow up.
D.    Children should be given the same toys as they grow up.
E.    58．According to the passage, we can give the child every kind of toys ________．
A．when he is two             B．when he is around four
C．when he is six              D．when he is eight
2.When a child is seven years old, what is the main source of learning?
A. Toys.      B. Books.    C. Jigsaws.   D. Paintings.
3. What is the article mainly about?
A．The importance of schooling.
B．The choice of toys for children.
C．The importance of pre-school education.
D．The role of play in a child’s development.
