19、First, we must think about how water gets into Lake Ponkapog. When it rains, water es into the lake from all around.

21、esses and then carries them into the lake. They pollute the water and kill the animals. Boats on the lake are also a problem. Lake Ponkapog is a popular place for motorboats. But oil and gas (油和汽) from boats often get into the lake. So more bad chemicals go into the water this way. People in Hartw

22、ell are worried. They love their lake and want to save it. Will it be possible? A clean lake must have clean rainwater going into it. Clean rainwater is possible only if people are more careful about chemicals at home and at work. They must also be more careful about gas and oil and other chemicals

26、 D. dirty lakes [參考答案] 一、 1. because of　 2. because　 3. because of 　4. because of　 5.because 二、 第(1)題make后接不帶to的feel。 第(3)題從句是were enjoying，故主句選過去式died。 第(7)題選引導賓語從句的that。 第(8)題從語義和結構上判定couldn't。 第(9)題是條件狀語從句，故選if。 第(10)題注意not…either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)選A。文章第二段最后一句話就能直接找到答案。 2)選D。文中第三自然段倒數(shù)第二行“the rain water picks up……”。 3)選C。很顯然干凈的雨水使湖泊干凈。 4)選A。挽救Ponkapog的關鍵當然在于少用污染。 5)選B。全文總觀可知，主要描述Ponkapog 為什么變臟。
