A 5R Rule for Environment
1. Reduce(减少)
If you want to reduce waste, you should use things wisely. A large number of trees are being cut down to make paper. If everyone uses a little paper carelessly and throw it out, soon we would not have any trees left. Other things are also being wasted, and people don’t know what to do with the waste in big cities. So it is necessary to reduce the waste.
2. Reuse(再利用)
You should always think of reusing the usable things before throwing them out. Give your clothes you do not use or the ones which are too small to the poor. In a family, you may pass on such clothes to younger brothers or sisters.
3. Recycle(回收)
Bottles, cans and paper can easily be recycled. By doing so we save lots of time and money. For example, coke cans are sent to a factory, where they are smashed(打碎) flat and melted(融化) and the metal things are made for new coke cans.
4. Recover (恢复)
When you buy a box of apples, there may be a few rotten apples, you have two choices: one is to throw the whole apples away, or you could cut off the rotten parts and use the good parts. In this way, you are recovering the eatable parts of food.
5. Repair(修补)
If one of the legs of your table is broken, you can repair it. If you want to change for better ones, it is better for you to sell the old things or give them to other people who can use them after doing some repair. It is true that North America is a “throw—away” society, but the time has come to change our way of life so that we can protect our environment. Every one of us should try our best.

Music is different from songs. Songs express feelings with lyrics(歌词), but music with tones (音调).Unlike songs, music tones in themselves have no specific meanings. Different people may get different things from the same musical performance. Though some music works are difficult to understand, people need music in their daily life because it brings fun to them. Different people like different music: some love classical music, and others take an interest in pop music. Most young people like pop music.
Pop music began in the USA and became popular around the world during the 1950s and 1960s.The best-known early kind of pop music was “rock and roll”. Pop music has taken the place of (取代)native music in many parts of the world. It has caused the number of people for “jazz” music to become much smaller than in the 1950s and earlier and it has now begun to become the most popular. Much pop music is without artistic value (艺术价值), but the works of some pop singers such as the Beatles, Bob Dylan, the groups like Pink Floyd and Crosby are excellent. And there is still great interest in it today. Pop music concerts and festivals are held all over the world. 
小题1:The biggest difference between music and songs is ________.

You either have it, or you don’t—a sense of direction, that is. But why is that some people would find their way across the Sahara without a map, while others can lose themselves in the next street?
Scientists say we’re all born with a sense of direction, but it is not properly understood how it works. One theory(理论) is that people with a good sense of direction have simply worked harder at developing it. Research being carried out at Liverpool University supports this idea and suggests that if we don’t have it, we lose it.
“Children as young as seven have the ability to find their way around,” says Jim Martland, Research Director of this project. “However, if they are not allowed out alone or are taken everywhere by car, they never develop the skills.”
Jim Martland also emphasized(强调) that young people should be taught certain skills to improve their sense of direction. He makes the following suggestions:
If you are using a map, turn it to the way you are facing.
If you leave your bike in a strange place, put it near something like a big stone or a tree. Note landmarks on the route as you go away from your bike. When you return, go back along the same route.
The simple way of finding your direction is by using lines such as streets in a town, streams, or walls in the countryside to guide you. Count your steps so that you know how far you have gone and note any landmarks such as tower blocks or hills which can help you find out where you are.
Now you will never get lost again!
小题1:Scientists believe that            .
A.only some babies are born with a sense of direction
B.people never lose their sense of direction
C.people learn a sense of direction as they grow older
D.everybody has a sense of direction from birth
小题2:What is true of seven-year-old children according to the passage?
A.They never have a sense of direction without a map.
B.They have a sense of direction and can find their way around.
C.They should never be allowed out alone if they lack a sense of direction.
D.They can develop a good sense of direction if they are driven around in a car.
小题3:If you leave your bike in a strange place, you should             .
A.tie it to the tree in order to prevent it from being stolen
B.draw a map of the route to help remember where it is
C.take the different routes when you come back to it
D.remember something easily recognizable(可辨认的) on the route
