　　　　1、同學(xué)們，看到下面的四幅圖片及相應(yīng)的報(bào)道后，你感到最擔(dān)憂的是哪兩種情形?請(qǐng)簡(jiǎn)述你擔(dān)憂的理由并提出建議或希望。要求：

　　　　⒈ 從所給素材中任選兩種情形進(jìn)行闡述，不可多選或少選。

　　　�、� 條理清楚，意思連貫，語句通順，標(biāo)點(diǎn)正確;⒊ 詞數(shù) 80 ～ 100。

　　　　參考詞匯： 建議 suggest v. suggestion n.氣體 gas n.　 污染 pollution n.

　　　　THE POLLUTIONS

　　　�、� One third of the world's people don't have enough clean water.

　　　　② More and more diseases are caused by polluted air.

　　　�、� People are disturbed quite often by kinds of noises.

　　　　④ Every person in our city makes about 1.8 kilos of rubbish every day.

　　　　The environment is becoming worse and worse. There are many kinds of pollution I worry about. The most serious two are water pollution and air pollution, because people can't live healthily with dirty water and polluted air, nor can animals. More and more diseases are caused by polluted air.

　　　　I think factories should not pour dirty water into the river directly or produce more waste gas. We'd better go on foot or by like instead of by car, because more cars mean more waste gas. We should make our world more and more beautiful.
