23、Li Hua is a primary school student and he enjoys drawing very much．

    One day，he went to the small woods not far from the town to draw from nature，carrying a drawing board．He was glad to find a tree living although the rest had been cut down．“Let me start work at once，”he thought and began to set up his board．

    Just then a strong young man came with a big axe and got down to cutting the tree．Soon he cut it down and pulled it away．

    When Li Hua got ready and turned back to draw，he found the tree had disappeared．

“Dear me！Where on earth is the tree？”Li Hua wondered，disappointed．

    From the story above，we can see it's high time that public awareness should be raised to keep the ecological balance，otherwise we would destroy not only the natural habitat of wildlife but our own living space as well．Besides，more legislation is needed to protect the environment．
