The world is nor only hungry，but it is also t 1  for water．This may seem strange to you，since nearly 70％of the earth is c 2 with water：But about 97％of this huge amount is sea water，or salt water．Man can only drink and use the other 3％——the fresh water from rivers，lakes，

underground，and other sources. Even w 3 ，some of it has been p 4 ．Now our need for water is i 5  -almost day by day．We must take steps to solve this prob1em，or we can’t a 6 a worldwide water shortage later on．

We all have to learn how to  s 7  water．One of the first steps is to develop ways of reusing it．

Today in most large cities，water is used only o 8  and then sent out into a sewer system(下水道)．But it is possible to get used water to a purifying(净化)factory．There it can be purified so t9   it can be used again．

    The world’s water shortage is a big p10 for humans．We must save every drop of water and keep our rivers and lakes clean．

If you have to choose a “Person of the Year” for 2005 , who will you pick ？For many of us ,the choice might not be a person at all . It would be Mother Nature（大自然母亲）.

While the world was still getting over the Indian tsunami（海啸）of December 2004 . Mother Nature went on showing her power throughout 2005 .

From July to October, about seven typhoons（台风）hit China’s coastal（沿海的）area.In August , the whole New Orleans city in the US was hit with its worst 一ever natural disaster , Hurricane Katrina . In early October , an earthquake in Pakistan killed more than 70,000 people .

Mother Nature was trying to give us a message:humans need to take responsibility（duty ) for the earth . She was just fighting back .

It is we humans who burn coal and oi1 to make electricity and power cars . This makes huge amount of greenhouse gases , which cause global warming .

It is we humans who cut forests and fill lakes to make space for buildings.This leaves fewer trees and lakes to keep floods（洪水）from rushing to towns and cities .

We need to work hard to ease（缓解）Mother Nature’s anger , or we’11 see more years of disasters.For example , we can start to use less electricity . Turn off lights , TVs and computers when we’re not using them . We can plant trees . One new tree a year from each of us can make a forest. Forests not only hold floods , they also take in greenhouse gases.
