考点规范练21(必修5Unit1)Ⅰ.阅读理解Indian scientists have designed a new device which they hope will solve one of the biggest problems with the use of solar energy. They call the device a solar tree. Solar trees have metal “branches” extending from a tall, central pole at different levels. Each branch holds a photovoltaic (光电的) panel, also called a solar panel. These panels are flat surfaces that collect energy from the sun and turn it into electricity.Daljit Singh Bedi is the chief scientist at the Council of Scientific and Industrial Research, or CSIR, in New Delhi, India. The CSIR laboratories are where the solar tree was designed.Bedi says the shape of the solar tree makes it possible to fit more photovoltaic panels in a space than traditional systems do.“It takes about 4 square metres of space to produce energy which otherwise would have required 400 square metres of space,” he says.Scientists believe the energy a solar tree collects will be enough to power five homes. The solar trees will make it easier to provide solar energy for homes in cities, they say. The solar trees will also take less space from farmers in rural areas. And they will collect more energy than normal photovoltaic panels on the tops of buildings, because their design helps with placement of solar panels in a way that they are exposed more to the sun.India is the world’s third largest producer of greenhouse gases. The country has promised to reduce its rate of greenhouse gas production.The cost of photovoltaic panels has gone down in recent years. This has made solar power cheaper and easier to use. But it is still not clear how useful these new developments in solar power technology are.1.What does Bedi say about the solar trees?A.They are energy-consuming.B.They are space-saving.C.They are easily accessible.D.They have geographical limitation.2.What makes the solar tree collect more energy?A.The hi-tech materials built in the panels.B.The number of panels fixed on it.C.The correct placement of the tree.D.The flexibility of its design.3.What’s the purpose of the passage?A.To introduce a new technological invention.B.To explain why scientists design solar trees.C.To describe the features of solar trees.D.To show the benefits of solar power technology.Ⅱ.完形填空(2020·全国Ⅲ)As a businesswoman,I care deeply about my customers.But like anyone for whom you feel affection,1 can also drive you mad.They’ll come rushing in,2 their handbag’s been stolen.They’ll3 that they left it in the changing room,create havoc(混乱) and then 4 it had been in their car all the time.They’ll have out half the 5 in the shop,and want the only style you don’t have left in a 6colour.I do know how upset the shop staff can get,but I try to persuade them to keep 7.I remember the first really 8 customer we had at Covent Garden.She was 9 absolutely everything,nothing was right and I was rather 10 that she became a“regular”.After a while,she11 for the way she behaved at the beginning.She had split up with her husband the week before,was living in a flat 12,and since she’d found it too much to cope with(应对),she’d taken it out on 13 people.That taught me a valuable 14 and I pass it on to the people who 15 in the market.Don’t take it 16.If a customer is rude or difficult,just think “Maybe she’s had a row with her husband.Maybe her child’s not 17.”Always water it down and don’t let your ego(自我) get 18.If you do,you won’t be able to 19 it and the whole thing develops into an unpleasant scene and that 20 everyone’s day.1.A.shopkeepers B.customersC.salespersonsD.receptionists2.A.saying B.pretendingC.guessingD.replying3.A.agree B.promiseC.imagineD.swear4.A.forget B.decideC.discoverD.assume5.A.foods B.cataloguesC.belongingsD.goods6.A.particular B.differentC.matchingD.natural7.A.fighting B.smilingC.waitingD.changing8.A.generous B.politeC.carelessD.difficult9.A.curious about B.displeased withC.patient withD.uncertain about10.A.relaxed B.delightedC.surprisedD.embarrassed11.A.searched B.arguedC.prayedD.apologized12.A.by chance B.by herselfC.on purposeD.on duty13.A.rude B.suchC.otherD.lonely14.A.lesson B.trickC.skillD.trade15.A.work B.shopC.meetD.quarrel16.A.kindly B.secretlyC.personallyD.casually17.A.ready B.awayC.upD.well18.A.out of sight B.in the wayC.behind the sceneD.above the law19.A.stress B.expectC.handleD.blame20.A.ruins B.makesC.startsD.savesⅢ.语篇填空Dujiangyan is the oldest man-made water system in the world,and a wonder in the development of Chinese science and technology.1.(build) over 2,200 years ago,this amazing engineering 2.(achieve) is still used today.In ancient times,the region in which Dujiangyan now stands 3.(suffer) from regular floods caused by overflow from the MinjiangRiver.4.(help) the victims of the flooding,LiBing,the region governor,together with his son,decided to find a solution.Li designed a series of channels built at different levels along Mount Yulei that would take away the floodwater while leaving the river flowing naturally.5.(good) still,the extra water could be directed to the dry Chengdu Plain,making 6.suitable for farming.Once the system was finished,no more floods occurred and the people were able to live 7.(peaceful).Today,Dujiangyan is admired by scientists from around the world because of one feature.Unlike modern dams 8. the water is blocked with a huge wall,Dujiangyan still lets water flow through the Minjiang River naturally,9.
