Wherever we go, we can see that paper, bottles and cans are thrown away; food     1     (waste) just because of its poor taste; clothes are thrown around simply due to their old fashion Not only things and money are wasted, but natural resources are wasted as well.     2     (tree) are cut down merely for fuel; wildlife is killed     3     (simple) for food; coal and minerals are exploited (开采) in     4     bad way.

The worst example of man’s waste is the waste of time. Many people tend to spend their time on     5     (worth) things, such as wandering about (漫步) in the street, gossiping in the office, or     6     (sleep) too much during the day. As we know, time is so valuable to us that it never returns if it     7     (pass) by.

It is time     8     (call) for an end to waste. On the one hand, we must save natural resources and make full use of them,     9     is very important to our future; otherwise human beings will be faced with the lack of natural resources and suffer     10     pollution caused by waste. On the other hand, we must value our time. Only with our time devoted to study and work for the people will we never regret the life we have had.
