People didnt have modern machines. There was no modern medicine, either. Life today has brought new problems. One of the biggest is pollution (污染). Water pollution has made our rivers and lakes dirty. It kills our fish and polluted our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution. Its bad to all living things in the world. Cars, planes and factories all pollute our air every day. Sometimes the polluted air is so thick that it is like a quilt over a city. This kind of quilt is called smog (烟雾). Many countries are making rules to fight pollution. Factories must now clean their water before it is thrown away, they mustnt blow dirty smoke into the air. We need to do many other things. We can put waste things in the dustbin and not throw it on the ground. We can go to work by bus or with our friends in the same car. If there are fewer people driving, there will be less pollution. Rules are not enough. Every person must help to fight pollution. ( ) 38. Hundreds of years ago, life was much harder than it is today because .

Our class discussed what to do to protect our environment at school. And the next day, we volunteered to clean up the streets. Some of us picked up rubbish. Others put dustbins on both sides of the streets. The dustbins were painted two colors: green and yellow. The green ones were used for recyclable waste and the yellow ones for non-recyclable waste. In this way, we can not only make good use of waste but make people form a good habit.Yours,Kathy精讲巧练1. We are trying to save the manatee. 我们在尽力挽救海牛。（1.）本句的时态是现在进行时，表示现阶段正在做的事情。现在进行时所表示的动作并不一定在说话 的时刻进行，而是在包括说话时刻在内的一段时间当中进行。 例如：My mother is writing a novel now. 我妈妈目前在写小说。（2.）动词短语try to do something的意思是“尽力做某事”，实际做与不做视情况而定；try doing something表示“试着做某事”，即动作真的进行了或者正在进行。 例如：He tried to read more, but it was too dark to read. 他想要多看会书，但是天太黑了以至于不能看了。随时练【考例】They are trying _ the child but they fail at last.A. save B. to save C. saved D. saves【答案与解析】答案是B。动词try的后面用动词不定式表示“尽力做某事”的意思。从句子的意思“他们在尽力挽救那个男孩，但最后失败了”可以判断是用动词不定式。2. I am like this animal because I am strong and intelligent. 我像这种动物，因为我强壮而且聪明。（1.）句子的like是介词，它的意思是“像”，它和一些连系动词be，look和seem等连用构成动词短语 表示“长得像、看起来像、似乎好像”的意思。 例如：It looks like my cat. 它看起来像我的猫。（2.）like的前面可以用very, much，rather，quite等修饰表示“很像、非常像、相当像、十分 像”的意思。 例如：You look very much like your father. 你看上去非常像你的爸爸。随时练【考例】The boy _ his mother, not only tall but also thin.A. likes B. like C. look like D. looks like【答案与解析】答案是D。本句子的like是介词，和连系动词look连用表示“长得像”的意思，主语是第三人称单数形式，所以连系动词用looks。3. There used to be a lot of manatees. 过去有许多海牛。句型there used to be是there be的中间加动词短语used to表示“过去曾经有而现在没有”的意思。There be的中间可以加will表示将来有；加情态动词may/can/must表示“可能有、一定有”的意思。例如：There used to be a tall building in front of our school. 在我们的学校前面曾经有一座大楼。随时练【考例】There _ be an English party tomorrow. Would you like to go with me?A. can B. may C used to D. will【答案与解析】答案是D。本句子的时间状语是tomorrow表示一般将来时，所以用will表示“将来有”的意思。4. I have visited a lot of zoos in my life, and I have never seen one I liked or one that was suitable for animals to live in. 我一生中参观过许多动物园，我从未见过一个我喜欢的或者适合动物住的。（1.）连词and引导的是并列句，第一个句子是现在完成时I have visited a lot of zoos in my life；第二个句子中的动词seen后面用两个宾语one。第一个one有定语从句I liked 修饰，第二 个one有that引导的定语从句修饰。（2.）动词短语be suitable for somebody to do的意思是“适合某人做某事”，句子后面的to live in中的in不能省略。随时练【考例】There is not enough space for everyone _.A. to stand on B. to stand C. standing on D. standing【答案与解析】答案是A。本句子是考查动词不定式的用法，for everyone to stand on中的介词on不能省略，因为它带有逻辑宾语，即前面的名词space，去掉on就成了stand a place，应该是stand on a place。5. They are like living textbooks for young people. 它们就像年轻人的活教科书。（1.）句子的living是现在分词作形容词用，它的意思是“活着的、使用中的”。 例如：She has no living relatives. 她没有活着的亲人了。（2.）living还可以作名词用，它的意思是“生计”。 例如：She earns a living as a writer. 她靠写作维持生计。随时练【考例】They want to buy some _ fish to offer the guests.A. living B. lived C. died D. dying【答案与解析】答案是A。本句子是用形容词living修饰后面的名词fish表示“活着的鱼”，从句子的意思可以判断是用living。6. They provide homes for many endangered animals，and help to educate the public about caring for them. 他们为许多濒临灭绝的动物提供住所，并教育人们应该很好地照顾好它们。（1.）动词provide的意思是“提供、供应”，它可以构成动词短语provide something for somebody和provide somebody with something。 例如：They provide some drinking water for us. 他们为我们提供一些饮用水。 They provide us with some useful information. 他们为我们提供一些有用的信息。（2.）动词短语care for的意思是“喜欢、在意、照顾”。 例如：I dont really care for red wine. 我其实并不喜欢红葡萄酒。 Who can care for me when I am old？我老了谁来照顾我？随时练【考例】Can you provide us _ some useful books?A. for B. with C. of D. on【答案与解析】答案是B。本句子是考查动词短语provide with的用法，provide somebody with something是“向某人提供某物”的意思。7. I urge all of your readers to visit our own wonderful zoo, soon. 我诚恳地要求你们所有的读者尽快来参观我们自己的精彩动物园。（1.）动词urge的意思是“强烈要
