In many cities, hundreds of people 16 bikes to work every day. In the New York City, some bike riders have even founded a group: Bike for a Better City. They say if more people ride bikes to work, there would be 17 cars and less dirty air.For several years this group has tried to gather help for bike riders. They want to have special roads 18 bikes only, because when bikes and cars use the same roads, there may be accidents. Bike for a Better City thinks if there were bike roads, more people would use bikes.But no bike roads have been established 19 . Not everyone thinks it is a good 20 . Drivers dont like it, and some shop owners dont like it, 21 . And most people live 22 far from the city to travel by bike. Still, 23 has been done about it. On Saturdays and Sundays, the largest open park in New York is 24 to cars, and the roads may be used by bikes only, but the group still says this is not enough and goes on fighting 25 bike roads. I think there will be more bike roads in the future.( )16.A.onB.rideC.byD.take( )17.A.fewerB.lessC.manyD.more( )18.A.untilB.forC.asD.of( )19.A.yetB.alreadyC.stillD.once( )20.A.hopeB.wayC.helpD.idea( )21.A.soB.andC.alsoD.either( )22.A.veryB.quiteC.tooD.so( )23.A.everythingB.somethingC.anythingD.nothing( )24.A.closedB.openC.openingD.closing( )25.A.getB.to getC.askD.to ask.阅读理解。（30分）(A) Air pollution comes from factories, power stations and cars. Chemicals in the smoke from power stations cause a lot of damage（损害；毁坏）. They can travel hundreds of miles in the wind before falling to the ground in the rain. And this “chemical rain” gradually（逐渐地）destroys trees in the forests and kills fish in the lakes. In Germany, over 50% of the countrys trees had been damaged by the year 1986.Time and time again there are serious accidents that pollute the air. In 1986 there was a serious accident at a nuclear power station in Russia. A cloud of radiation flew across the whole Europe. It is said that 125,000 people died in Russia as a result of illness caused by this accident.In 1984 there was a serious accident at a factory in India and a cloud of dangerous gas covered the town of Bhopal. Over 2,500 people were killed that night, and hundreds of thousands of people were injured (受伤的). Many of the injured lost their sight.根据短文内容，选择正确答案。( )31.Air pollution comes from _.A.factoriesB.power stationsC.carsD.all of the above( )32.According to the passage, which sentence is TRUE?A.Chemicals in the smoke from power stations cant travel far in the wind.B.“Chemical rain” is good for the trees.C.Chemicals in the smoke from power stations are very safe.D.“Chemical rain” is bad for our environment.( )33.In Germany, how many trees had been damaged by the year 1986?A.A quarter.B.A half.C.Three quarters.D.A third.( )34.What was the result of the accident that happened in Russia in 1986?A.Over 2,500 people were killed.B.Many people couldnt walk.C.Many people lost their sight.D.Compared with (同比较) the accident in India, more people died.( )35.From the sentence “Many of the injured lost their sight.” we can know _.A.the gas covered the town of Bhopal at that time was poisonous (有毒的)B.gradually the injured could see everythingC.many of the injured couldnt see anything any moreD.Both A and C(B) Its important to learn things about protecting environment. Heres 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 dont know what to do with waste in big cities, so its 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 dont 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 theyre 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, its better for you to sell the old ones or give them to other people who can use them after doing some repair.根据短文内容，选择正确答案。( )36.The “Reduce” rule mainly requires us _.A.to use things wiselyB.to cut down many treesC.to use paper carelesslyD.to use more and more things( )37.Whats the right order of recycling cola cans?a.smash them flatb.collect the used cansc.smelt themd.send them to a factoryA.a-b-c-dB.d-c-b-aC.b-d-a-cD.b-d-c-a( )38.The “Reuse” rule mainly requires us _.A.to throw away the old clothesB.to collect waste paper and soft drink cansC.to use bot
