水是生命之源，但水資源短缺和水污染已成為世界最嚴(yán)重的資源環(huán)境問題之一，需要引起極大關(guān)注．假如你是李華，請你給 China Daily投稿，表達一名中學(xué)生對此問題的關(guān)心．要點如下：
1．世界人口增多，工農(nóng)業(yè)發(fā)展需要越來越多的水；
2．河流、湖泊污染嚴(yán)重；
3．全民動員，保護水資源．
注意：
1．詞數(shù)120左右；
2．可以適當(dāng)增加細節(jié)，以使行文連貫．
Dear editor，

As we all know， no life can live without water． Water is of great importance to all living things． Not only do people need water， but also plants and animals need water．
However， as the population grows and industry and agriculture develop， more and more water is needed and used． Besides， many beautiful rivers and lakes have been polluted by the waste water from factories， and the polluted water even does harm to people as well as other living things．
Therefore， it's high time we took measures to prevent water from being polluted， to save water as much as possible and to protect the water source on the earth． Otherwise， the last drop of water on the earth will be human's tear!
Yours，
Li Hua
