What does it feel like to break a bone (骨頭)? It’s different for everyone, but the pain is often sharp (嚴(yán)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(xì)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

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(chǎn)→b→c→dB．a(chǎn)→c→b→dC．a(chǎn)→d→c→bD．d→a→b→c
小題4:The underlined word “heal” in Paragraph 3 is closest in meaning to “______”.
A．break againB．become worse C．wound or hurtD．become healthy again
小題5: Where would you probably read this passage?

The first telephone cards, produced in 1976, were Italian. Five years later the first British card appeared, and now you can buy cards in more than a hundred countries. People usually start collecting cards because they are small and light and you do not need much space for them.

Every time you turn on the television or take a ride in a car ,you could be adding to a problem called acid rain(酸雨). In this article, you’ll learn how acid is created, and how it affects us, and more importantly, what we all can do to prevent it.
How is acid rain created?
When people use fuels(燃料), such as coal and gasoline, poisonous gases are give off. When these gases mix with rain, acid rain forms.

How can we prevent acid rain?
We need to cut down on the pollution that gets into our air. Turn off lights, television, and other electrical appliances if you are not using them, Walk or take a bike whenever possible. If you are travelling a long distance, take a bus or train to save fuel.

How do you remember the way to your house? Where do dreams come from? It is your brain(大腦) that does these things. A British scientist showed that “sleep can improve one’s memory.” It’s not a dream for students to study when they sleep. In fact, your brains is working day and night. If you learn words before bed, a certain part of the brain may help you to remember the words while you sleep. What’s more, another scientist in the USA found that there was a “talent button(天才按鈕)” in the human brain. It might make a person more talented.
There are more interesting things about the brain. Your brain uses less energy than a fridge light. Just two bananas can give the brain enough energy to work for a whole day. According to some scientists, yawning(打哈欠) keeps our brains “cool”, which makes us think quicker.
Here are some pieces of advice to keep a good brain:
Eat healthy food.
Get a lot of playtime or exercise.
Don’t drink or smoke.
Use your brain a lot.
小題1: A British scientist found out that ________ could improve our memories.
A．drinkB．dreamsC．sleepD．bananas
小題2: According to the passage, if we want to have a good brain, we should ________.
A．use our brains moreB．sleep fewer hours

小題3:Which of the following is TRUE according to the passage?
A．Our brains only work in the daytime.
B．Our brains need much energy every day.

There is not enough oil in the world now. As time goes by ,it becomes less and less ,so what are we going to do when it runs out? Perhaps we will go back to use horses ,carriages and bicycles .
In the Second World War ,some people didn＇t use gas made from petroleum （石油）in their cars .They made gas from wood and plants instead . The cars didn＇t go fast ,but they ran ,so this was better than nothing. However, in the future, we can＇t cut down all our trees to make gas; we need our trees for other things, too.
Besides different types of gas, we can also use electricity(電)to run our cars but first we must make the electricity ！Some countries have coal and they make electricity with that, but we might not always have coal, either. Other countries have big ,strong rivers and they can use the power of water to turn turbines(渦輪機(jī)) and make electricity more easily and cheaply.
We are also able to get power from the ocean tides. We put turbines into the mouth of the river .Then the tide comes in ,the water turns the turbines and then it goes out ,it turns them again.
Which of these ways will be used to run our cars in the future?
小題1:When might people have to go back to using horses and carriages?
A．When they are poor
B．When they run out of oil
C．When they need more exercise
D．When there aren＇t any big trees in the world

A．how to run our cars
B．what to do when oil runs out
C．different types of gas

Scientists are placing robotic dogs in the homes of lonely old people to test whether they can improve the quality of life for humans. Alan Beck, an expert(專(zhuān)家) in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study on the effect of robotic dogs on old people’s depression (沮喪) , physical activity, and life satisfaction.
In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, scientists will collect baseline data(數(shù)據(jù)) for six weeks. These old people will keep a diary to note their feelings and activity before and after AIBO. Then, the scientists will review the data to test if it has produced any changes in the life of its owner.
“I talk to him all the time, and he responds to my voice,” says a seventy-year-old lady. “When I’m watching TV, he’ll stay in my arms until he wants down. He has his own mind.”
The AIBOs respond to certain orders. The scientists say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns.
“At the beginning, it was believed that no one would relate(與……相關(guān)) to the robotic dog, because it was metal and not furry.” Beck says. “Hopefully, down the road, these robotic pets could become a more-valuable health helper. They will record their masters’ blood pressure, oxygen levels or heart rhythms(心律). AIBOs may even one day have games that can help stimulate(刺激) older people’s minds.”
小題1:The purpose of Beck and Edwards’ study is to _____________.
A．understand human-animal relationship
B．make lonely old people’s life better
C．find the causes of old people’s loneliness
D．improve the animal-assisted research
小題2: In the research, the old people are asked to _____________.
A．note the activities of AIBOs
B．keep AIBOs at home for 12 weeks
C．record their feelings and activity
D．study the collected information
小題3:What does the underlined word “removes” mean?
A．moves againB．is movableC．doesn’t needD．need
小題4:What is the better point of AIBO than live dogs?
A．It is easier to keep at home.
B．It can help the disabled people.
C．It responds to all the human orders.
D．It can watch TV with its owner.
小題5:The writer seems to suggest that the future robotic dogs may__________.
A．cure certain diseasesB．keep old people active
C．change people’s ideasD．look more like real dogs
