Here's a 4Rs rule for us.·ReduceIf you want to reduce waste, you should use things wisely (明智的). A large number of trees are being cut down to make paper. If everyone uses paper carelessly and then throws it away, soon we would not have any trees left. Some other things are also being wasted, and people don't know what to do with waste in big cities, so it's necessary to reduce waste.·ReuseYou should always think of reusing the usable (可用的) things before throwing them away. Give your clothes or things you don't use to the poor. In a family, you may pass such clothes on to your younger brothers or sisters.·RecycleBottles, cans and paper can easily be recycled. By doing so we save lots of time and money, for example, cola cans are sent to a factory, where they're smashed flat（压平）and smelted (熔化), and the metal things are made into new cola cans.·RepairIf one of the legs of your table is broken, you can repair it. If you want to change for better ones, it's better for you to sell the old ones or give them to other people who can use them after doing some repair.（11）The "Reduce" rule mainly requires us_____.    A．to use things wisely B．to cut down many treesC．to use paper carelessly D．to use more and more things（12）What's the right order of recycling cola cans?  a. smash them flat      b. collect the used cansc. smelt them         d. send them to a factoryA．a-b-c-d B．d-c-b-a C．b-d-a-c D．b-d-c-a（13）The "Reuse" rule mainly requires us_____.    A．to throw away the old clothesB．to collect waste paper and soft drink cansC．to use both sides of paperD．to give the old but usable things to the poor（14）Which sentence is about the "Repair" rule?   A．When you leave a room, turn off the lights.B．Take a cloth bag when you go shopping.C．Don't use plastic bags.D．If your chair is broken, you can repair it.（15）Which is the best title for this passage?   A．A 4Rs rule B．Protect the environmentC．Save energy D．Good habitsB    Our living environment is being polluted faster than before and it seems nobody can prevent it. Time brings us more people, and more people bring us more industry, more cars, larger cities and growing use of man-made materials.How can we understand and solve this problem? The fact is that pollution is caused by man —by his desire (欲望）for a modem way of life. So we are often ready to offer everything: clean water, good food, our health and the future of our children. There are more people from the countryside moving into the cities and enjoying the modem society. But as the technological momentum (势头) has grown in the last twenty years, pollution has become a serious problem.Now we have to stop to ask ourselves where we are going and why. It makes one think of the story about the airline pilot who told his passengers over the loudspeaker, "I've got some good news and bad news. The good news is that we're going at 530 miles per hour. The bad news is that we're lost and don't know where we are going." The sad fact is that this problem becomes a true story when speaking of our modem society.（16）Man fails to stop the world from being polluted because       .   A．the population of the world is increasing fastB．people use too many machinesC．we have more and more industryD．we are producing more cars, trucks and buses（17）People from the countryside crowd into cities for         .   A．good jobs B．enjoying the modern lifeC．Fun D．becoming tired of their hometown（18）Man cares about            most according to the passage.   A．industry B．clean waterC．health D．the future of the children（19）The story about the airline pilot tells us that           .   A．man knows where the society is goingB．the pilot doesn't know where to goC．man has done little with the problem of pollutionD．the pilot is not good at flying（20）The main idea of this passage is          .   A．pollution has become a serious problemB．man should slow down the speed of development to stop pollutionC．the pilot would like to make a contribution to protecting the environmentD．as industry is growing fast, pollution is the natural result C Air pollution is one of the most common types of pollution in the world nowadays. It is quite serious in many places, especially in big cities. It can do great harm to our environment such as making the earth warmer, causing acid rain or destroying the ozone layer. As for human beings, air pollution causes all kinds of breathing problems.    There are several reasons for air pollution. Firstly, many cities have a lot of factories and there we need to make food, clothing and other things. Every year these factories pour millions of tons of smog into air. Secondly, power factories can also give out harmful air. For example, in 1986 there was a bad accident at a nuclear power station in Russia. A cloud of radiation crossed the whole Europe. It is said that 125,000 people died in Russia as a result of illnesses caused by this accident. Thirdly, there are more cars in cities now. Once they are out in the streets, they will take in fresh air and give out dirty gas. Besides, smoking cigarettes also makes air pollution worse as will as damaging(损害) our health.  （21）According to the passage, which of the following is NOT caused by air pollution?        A．Global warming.B．Acid rain.C．Breathing problems.D．Accidents at the nuclear power station.（22）How many reasons for air pollution are mentioned in the passage?        A．Two. B．Three. C．Four. D．Six.（23）125,000 people in Russia died from _______.        A．water pollution B．air pollutionC．a car accident D．cancer （24）The underlined word “they” refers to _______.        A．cities B．cars C．cigarettes D．people（25）The main idea of the passage is about _______.        A．what is air pollution B．how to stop air pollutionC．the reasons for air pollution D．how to make air cleanD    All over the world in the twenty-first century, people can get new energy in many ways.Energy from the wind. People use the power of the wind．It is a clean source(来源) of energy, and there is lots of it. However, if the wind does not blow, there is no wind energy.Energy from the water. When water moves from a high place to a lower place, it has the power to make electricity. Waterpower produces enough energy for 40, 000 people in a town. Waterpower gives energy without pollution. However, people have to build dams(大坝) to use this energy, and building dams is very expensive.Energy from the earth. There is heat in the rocks under the earth. Scientists use the heat to make geothermal(地热的) energy. San Francisco gets half of the energy from geothermal power. This kind of energy is cheap, but it is only possible in a few places in the world.Energy from the sun. Solar panels(太阳能电池板) on the roofs of houses and buildings can turn energy from the sun into electricity. These panels can create enough energy to heat the whole house during winter. Solar power is clean and plentiful(丰富的), but when the weather is bad, it can't produce power．（26）The second paragraph tells us that ________.      A．energy can come from the windB．people need windC．if there is no wind, there is still much energyD．there is much wind all over the world（27）Which is TRUE about waterpower?  A．Building dams is not very expensive.B．Four thousand people use waterpower in a town.C．When water moves from a place low to a higher place, it has the power to make electricity.D．Waterpower has no pollution.（28）________ can make geothermal energy.      A．Many countries B．Many places except San FranciscoC．Only a few places in the world D．Every country and everywhere（29）Solar panels ________.      A．can work well in any weather    B．can also be used in winterC．must be placed(放置) in the houseD．can turn energy from the gas into electricity（30）The best title of this passage is ________.      A．Energy from the Wind             B．Energy from the WaterC．Energy from the Earth and the Sun   D．New Energy in the Twenty-first Century三、完成句子。（10分）根据所给中文完成句子，每空一词。每空1分。（31）我想阻止她抓那个球，但是她没有听到。 I wanted to 　                  　 her 　     　　         　 the ball, but she didn't hear me.（32）我想要茶而不是咖啡。 I would like tea 　        　　     　 coffee.（33）水污染导致我们城市切断供水两天。 The water pollution caused our city to　     　　     　 its water supply for two days.（34）当你离开教室的时候，应该随手关灯。 You 　     　　     　 turn off the lights when you leave the classroom.（35）说比做更容易。 　     　 said than　     　.我想阻止她抓那个球，但是她没有听到。 I wanted to　                  　her　              　the ball, but she didn't hear me.四、综合填空。（每空1分，共计10分。）Life today is （36）　     　(easy) than it was hundreds of years ago, but it has（37） 　        　(bring) new problems.

There are many kinds of pollutions around us, such as air pollution, noise pollution, water pollution and light pollution. We can find that rubbish not only pollutes our environment but also harms people's health. So we should not throw rubbish everywhere. Some factories pour waste water into the rivers and the lakes. The behavior of these factories will pollute the water, and sometimes it can kill the fish living in them.We have only one earth. We must keep our environment clean and tidy. We must try our best to protect her, and make our home more beautiful.
