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.
小题1:The “Reduce” rule mainly requires(要求) us ______.
A. to use things wisely
B. to cut down many trees
C. to use less paper
小题2: The right order of recycling coke cans is ______.
a. collect the used cans b. melt them c. smash them flat d. send them to a factory
A. a b c d B. a d c b C. d b c a
小题3:The “Recover” rule mainly requires us ______.
A. to throw waste thing away
B. to cover waste thing with the earth
C. to get back the useful parts
