If we walk by the rivers or drive past them which go through city． We can see the chemical factories near them pouring waste water into them without doing anything to it all the time．As a result, the fish and kinks of animals in them are dying out because of the polluted water．Many trees have been cut down while no more trees have been planted in the places．People leave rubbish everywhere．All these have caused some serious problems．For example, the land is sandy, the air is less clean, even the temperature of the earth is rising． As we know, the 2008 Olympics will be hosted in Beijing．In order to improve our environment, we should plant more trees, sort the rubbish and put it into right dustbins and stop factories pouring waste directly the air or rivers． In word, nowadays the most important thing we can do is to protect the environment．
    如果我們走在河流或開(kāi)車(chē)過(guò)去，穿過(guò)城市。我們可以看到化工廠附近，他們把污水倒進(jìn)他們什么也不做這一切的時(shí)候。因此，在他們的魚(yú)和各種各樣的動(dòng)物死亡，被污染的水。許多樹(shù)木被砍伐雖然沒(méi)有更多的樹(shù)木被種植在地。人們到處亂扔垃圾。所有這些都造成了一些嚴(yán)重的問(wèn)題。例如，土地沙化，空氣不清新，甚至是地球的溫度上升。我們知道，2008奧運(yùn)會(huì)將在北京舉行。為了提高我們的環(huán)境，我們應(yīng)該種更多的樹(shù)，把垃圾放進(jìn)垃圾箱，權(quán)和阻止工廠把廢物直接空氣或河流?？傊?，現(xiàn)在最重要的事情是我們可以做的是保護(hù)環(huán)境。
