Is your schoolbag too heavy to carry? The e-schoolbag will help you. In fact, the e-schoolbag should perhaps be called an e-textbook. It is a small computer for students. Heavy schoolbags have been a serious problem for them for a long time. But the e-schoolbag will change everything.
It is much lighter than a usual schoolbag. Also, it is as small as a usual textbook, an exercise book and so on. They can be made into chips that are as small as a stamp. The students can read the text page by page on the “screen”, take notes, or even send e-mails to their teachers. All they have to do is to put the right chip into the e-schoolbag and press the button.
It is said that e-schoolbags have been put into use in some Chinese middle schools. In 2012, some students in Shanghai started to use e-schoolbags in the new term. Some say that e-textbooks can be easily broken. Some say it is not good to students’ eyes. But only time will tell us all.

Passage 5
Here in Siberia (西伯利亚), the winter is always very long and it’s very, very cold! It starts to snow in November and the snow won’t leave until May. The temperature is usually about -25℃, but it’s sometimes much colder. When it’s -35℃, children can’t go to school, but grown-ups still go to work! We wear a lot of warm clothes: socks and boots, sweaters and fur coats. All the houses have heating, so it’s never cold inside. In winter, we close the windows to stop the wind from getting in, and we don’t open them again until spring.
In spring and summer it rains a lot, and we don’t often see the sun. In summer it’s often about 25℃, but the weather is very changeable. One day it’s 25℃, and the next day it’s 10℃. People say that the weather was even colder in the past.

The building is shaking. A woman with a baby in her arms is trying to open the door, but fails. Finding no way, she rushes into her bedroom and there they survive the earthquake.
In a factory building, as the workshop floor swings under the terrible shaking, workers run for safety. Some hide(隐藏) under the machines and survive , but others who try to run outside are killed by the falling ceilings.?
These scenes, played by actors and actresses, are from a film of science education 《Making a Split Second Decision》 shown in 1998 on China Central TV in memory of Tangshan Earthquake.
By studying actual cases in the earthquake areas and scientific experiments, experts(专家)find that buildings remain untouched for the first 12 seconds of an earthquake.
In this short time, one has the best chance of surviving an earthquake by staying near the inside walls, in bedrooms and under beds, experts concluded in the film. “Earthquakes seem to catch the lives of those who run,” said many survivors in the earthquake areas, describing how their friends were killed on the doorways or along the stair steps as they tried to get out of the building.
Their advice was proved in the film, “Take a hiding-place where you are rather than run, unless you are sure you can reach a safe open place in ten seconds.”

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.
小题1:How many dangers of using social networks are mentioned in the passage?

小题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

小题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
