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) 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
小題2:How many ways are suggested to make electricity in the passage?

小題3:The passage is mainly about             .
A．how to run our cars
B．what to do when oil runs out
C．different types of gas
D．the way to make electricity

小題1:B
小題2:D
小題3:B

小題2:根據(jù)短文描述主要介紹三種發(fā)電方法，火力發(fā)電，水力發(fā)電和利用海洋潮汐，故選D。

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．a(chǎn)sking 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(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?
A．In a story book.B．On a poster.C．In a health care book.D．In a chemistry book.

Almost all of us have unpleasant habits. We all want to get rid of(擺脫) them, but we don’t know proper ways. Here’s some advice.
●Write down all the reasons why you want to stop some behavior. Look at the reasons very often.
●It’s clever to do something else when you want to stop your bad habits. If you get angry easily, for example, you can go out for a walk.
●Decide what you’ll do to reward(獎勵) yourself if you really get rid of your bad habits.
●If you get too heavy, keep junk food out of your house.
●Bad habits develop over years, so you can’t get rid of them very soon. So you should be patient.
●Don’t be afraid to ask others for support. You can talk to your friends, family or other people. When you talk to them, they might be able to provide some advice that you can’t get from yourself.

We all need a healthy environment, but we produce waste every day and it does harm to our environment. Though we are young, we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. Here are some ideas for you to live a green life.
Remember these three words: reduce, reuse and recycle.
Reduce means “use less”. Don’t waste things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think if it is really necessary or maybe the old one will be just as good! When we do buy things, choose local products if possible, and try not to buy too many things from abroad.
Reuse means “use again”. Use things for as long as possible. When we buy things, make sure that they last a long time. We should take care of them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones. Don’t use a paper cup or a paper bag. It’s better to use a china cup and a lunch box because you can use them again.
Recycle means “change things into something else”. Although it takes energy to change something into something else, it’s better than throwing things away or burning them. Find out what can be recycled in your neighbourhood and take part in recycling programmes. We should also buy products made from recycled materials, such as recycled paper, to help save trees.
