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.                                             
【小題1】How many dangers of using social networks are mentioned in the passage?

A.2.B.3.C.4.D.5.

A.students could be put into unreal situations on the Internet

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

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.

Hands play an important part in our daily life. But do you know which of your two hands you use more? Very few people use both hands equally well.  Most of us are right-handed.  Only about five people out of a hundred are left-handed.  New-born babies can take hold of things with either of their hands, but in about two years they usually use their right hands.  Scientists don’t know why this happens.
Monkeys are our close relatives in the animal world. Scientists have found that monkeys like to use one of their hands more than the other, but it can be either hand.  There are as many right-handed monkeys as left-handed ones.  Next time you visit a zoo, watch the monkeys carefully, you will see that some of them will use their right hands and others will use their left hands.  But most of the people use their right hands better and this makes life difficult for those left-handed people.  We live in a right-handed world.

What does it feel like to break a bone (骨頭)? It’s different for everyone, but the pain is often sharp (嚴重). If the break is small, however, the person may not feel much pain at all. If you think that you or someone else has broken a bone, the most important things to do are to stay calm, make the hurt person comfortable, and call the doctor. Do not move the injured body part since movement could make it worse.
To treat the break, the doctor will need to take an X-ray. This gives the doctor the information he or she needs to set (接上) the bone: to put it back to its normal place. If the bone is large or it is broken in more than one place, the doctor may need to use metal pins (鋼釘) to set it. After the bone has been set, the next step is usually putting on a cast, the special, hard thing that will keep the bone in place for a month or two.
Your bones are excellent at healing themselves. Broken bones will produce many new cells (細胞) and tiny blood vessels (血脈). These cover both ends of the broken part, and close up the break until the bone is as whole and strong as before.
【小題1】Which of the following is the best title for the passage?

A.How to Know if a Bone is Broken
B.How Broken Bones Heal Themselves
C.Common Causes (原因) of Broken Bones
D.What You Should Know about Broken Bones
【小題2】When someone breaks his bone, the following should be done except ______.
A.asking the doctor for helpB.comforting the hurt person
C.moving the injured partD.staying calm
【小題3】Which is the correct order to treat the break?
a. take an x-ray  b. use metal pins to set it  c. put it back to its normal place  d. put on cast
A.a→b→c→dB.a→c→b→dC.a→d→c→bD.d→a→b→c

Even though global warming may have made the weather more mild, many animals are still hibernating(冬眠). It’s too bad that humans can’t hibernate. In fact we almost did.
Apparently, at times in the past, farmers in France liked a semi-state of human hibernation. So writes Graham Robb, a British scholar who has studied the sleeping habits of the French farmers. As soon as the weather turned cold, people all over the France shut themselves away and practiced the forgotten art of doing nothing at all for months.
In line with this, Jeff Warren, a producer at CBC Radio’s The Current, tells us that the way we sleep has changed since the invention of lighting.
When historians began studying texts of the Middle Ages, they noticed something referred to as “first sleep”, which was not clarified, though. Now scientists are telling us our ancestors most likely slept in separate periods. The business of eight hours’ continuous sleep is a modern invention.
In the past, without the artificial light, humans went to sleep when it became dark and then woke themselves up around midnight. The late night period was known as “The Watch”. It was when people actually kept watch against wild animals, although many of them simply moved around or visited family and neighbors.
According to some sleep researchers, a short of insomnia(失眠)at midnight is not a disorder. It is normal. Humans can experience another state of consciousness(清醒狀態)around their sleeping, which happens in the brief period before we fall asleep or wake ourselves in the morning. This period can be a creative time for some people.
Playing with your sleep rhythms(節奏)can be dangerous, as worry may set in. Medical science doesn’t help much in this case. It offers us medicines for a full night’s continuous sleep, which sounds natural; however, according to Warren’s theory, it is really the opposite of what we need.
【小題1】The late night was called “The Watch” because it was a time for people ______.

A.to set time to catch animals
B.to remind others of the time
C.to guard against possible dangers
D.to wake up their family and neighbors
【小題2】We can infer from the last paragraph that people should ______.
A.sleep in the way animals do
B.follow their natural sleep rhythms
C.keep to the eight-hour sleeping way
D.ask doctors for help if they can’t sleep
【小題3】What is the writer’s purpose in writing the passage?
A.To throw new light on human sleep.
B.To encourage people to sleep less.
C.To give some suggestions on insomnia.
D.To find out people’s hibernating history.

Scientists (科學家) think that many animals cannot see colours. The world is black and white to them. Scientists want to find out if (是否) dogs can see colours.
