It's important to learn about protecting our environment. Here is a 5R rule for us:
Reduce
If you want to reduce waste, you should use things wisely(明智地). A larger number of trees are cut down to make paper. If everyone uses paper carelessly, soon we will 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 use things wisely.
Reuse
You should always think of reusing the usable things before throwing them away. For example, you can give your clothes you do not wear any more to the poor. In a family, you may pass on such clothes to younger brothers or sisters.
Recycle
Bottles, cans and paper can easily be recycled. By recycling them we save lots of time and money. For example, Coke cans are sent to a factory, where they are smashed flat (压平) and melted(融化) and the metal things are made for new Coke cans.
Recover(恢复)
When you buy a box of apples, there may be a few rotten(腐烂的) apples, you have two choices(选择): One is to throw the whole apples away, or you can cut off the rotten parts and keep the good parts. In the way, you are recovering the eatable(能吃的) parts of food.
Repair
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.
( ) 1. The "reduce" rule mainly wants us ?.
A. to use things wisely B. to cut down many trees
C. to use a lot of paper D. to throw away your old things
( ) 2. What's the right order of recycling Coke cans?
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 D. c, a, b, d
( ) 3. The "recover" rule mainly wants us ?.
A. to throw waste things away
B. to cover waste things with earth
C. to get back the useful parts
D. to throw the whole things away
( ) 4. Which is the best way to do with your broken tables?
A. Throwing them away. B. Repairing them.
C. Selling them. D. Putting them away.
