Many birds and animals lived beside the water,which was full of fish. Now there are few birds, animals, andfish. The lake water is polluted (污染的). It is in a colour ofdirty brown, and it is filled with strange plants.How did this happen? First, we must think about how watergets into Lake Ponkapog. When it rains, water es into thelake from all around. In the past, there were forests allaround Lake Ponkapog, so the rainwater was clean.Now there are many homes around the lake. People often usechemicals (化学品) in their gardens. They use other chemicalsinside their housed for cleaning or killing insects (昆虫).There are also many businesses. Businesses use chemicals intheir machines or shops. Other chemicals fall onto the groundfrom cars or trucks. When it rains, the rainwater picks up allthe chemicals from homes and businesses and then carries theminto the lake. They pollute the water and kill the animals.Boats on the lake are also a problem. Lake Ponkapog is apopular place for motorboats. But oil and gas (油和汽) from boatsoften get into the lake. So more bad chemicals go into thewater this way.People in Hartwell are worried. They love their lake andwant to save it. Will it be possible? A clean lake must haveclean rainwater going into it. Clean rainwater is possibleonly if people are more careful about chemicals at home and atwork. They must also be more careful about gas and oil andother chemicals on the ground. And the mustnt use motorboatsany more on the lake. All these may change peoples lives.Only then can Lake Ponkapog be a beautiful, clean lake again.1) In the past, the water in Lake Ponkapog was made clean byA. forestsB. rainC. birdsD. fish2）Chemicals from homes and businesses .A. are always cleanB. can help the animalsC. are good for the lakeD. get into the rainwater3）Cleaner rainwater will mean .A. more boats on the lakeB. more dirty things in the lakeC. a cleaner lakeD. a dirtier lake4）To save Lake Ponkapog, people need to .A. be more careful about chemicalsB. use less waterC. grow fewer plants in the gardensD. use more motorboats on the lake5) The passage is about .A. boats on Lake PonkapogB. why the water is dirty in Lake PonkapogC. clean rainwaterD. dirty lakes参考答案一、1. because of 2. because 3. because of 4. because of 5.because二、第(1)题make后接不带to的feel。第(3)题从句是were enjoying，故主句选过去式died。第(7)题选引导宾语从句的that。第(8)题从语义和结构上判定couldnt。第(9)题是条件状语从句，故选if。第(10)题注意noteither的用法。答案：(1)B (2)D (3)A (4)B (5)C (6)C (7)B (8)A (9)D (10)A三、1)选A。文章第二段最后一句话就能直接找到答案。2)选D。文中第三自然段倒数第二行“the rain water picks up”。3)选C。很显然干净的雨水使湖泊干净。4)选A。挽救Ponkapog的关键当然在于少用污染。5)选B。全文总观可知，主要描述Ponkapog 为什么变脏。
