1、2021 届临朐第六中学高三英语第四次联考试卷及参考答案 第一部分 阅读(共两节,满分 40 分)第一节(共 15 小题;每小题 2 分,满分 30 分)阅读下列短文,从每题所给的 A、B、C、D 四个选项中选出最佳选项 A Personal Time Off(PTO)is something my wife and I created after having kids.We learned that,over time,a full life can leave little time for personal rest and for reflection,hanging out wit
2、h friends,or just being“off.”So,after a number of years,we make a change.If I can persuade you to take your own PTO,then these might help.Schedule it First of all,one of our favorite family sayings is“schedule it.”Sounds easy enough,but life gets complicated managing full-time work and full-time fam
3、ily.Put yourPTO time on the calendar and you make it a real thing.Be flexible and strict If you can schedule PTO at the same time each week,then all the better.Because our calendar can get rather full,flexibility in scheduling becomes a necessity.But being strict in actually taking the time each wee
4、k is more important.Skipping it once makes it easier to skip again.Take enough time My typical PTO lasts a couple of hours or longer.Sometimes it might be half the day depending on what Im doing.The goal is to spend enough time away to1et your shoulders drop.Do what you want to do Remember,PTO time
5、is about personal time to do what you want to do,not what you have to do.PTO time is about relaxation.Grab a friend and get a beer.Work can wait until tomorrow.1.What can be the first step to take the PTO?A.Persuade the family.B.Have a personal rest.C.Ask friends for advice.D.Make a time plan.2.What
6、 does the underlined part“let your shoulders drop”probably mean?A.Get you more focused.B.Have you feel relaxed.C.Shake your shoulders often.D.Make you feel more stressed.3.What does the text mainly talk about?A.Tips on how to take your time off B.Skills to manage work and family C.Advice on how to f
7、ree yourself D.Ways of scheduling your work B Improvements to energy efficiency,such as LED lights,are seen by many authorities as a top priority for cutting carbon emissions.Yet a growing body of research suggests that arebound effect could wipe out more than half of the savings from energy efficie
8、ncy improvements,making the goals of the Paris Agreement on climate change even harder to hit.A team led by Paul Brockway at the University of Leeds,UK,looked at the existing 33 studies on the impact of the rebound effect.First comes the direct rebound:for instance,when someone buys a more efficient
9、 car,they may take advantage of that by driving it further.Then comes the indirect rebound:fuel savings leave the owner with more money to spend elsewhere in the economy,consuming energy.Although the 33 studies used different methods to model the rebound effect,they produced very consistent estimate
10、s of its impact,leading the team to conclude that the effect wipes out,on average,63 percent of the anticipated energy savings.“Were not saying energy efficiency doesnt work.What were saying is rebound needs to be taken more seriously,”says Brockway.The idea that increased efficiency may not deliver
11、 the hopedfor savingsdates back to the Jevons paradox(悖论),named after the economist William Stanley Jevons,who,in 1865,observed that more efficient coal use led to more demand for coal.If the rebound effect does prove to be as big as suggested,it means future global energy demand will be higher than
12、 expected and the world will need far more wind and solar power and carboncapture technology than is currently being planned for.But that doesnt mean nothing can be done to limit the rebound effect.One answer is to double down on energy efficiency and do twice as much to achieve the same effect.4.Wh
13、ich of the following is a rebound effect?A.A man uses LED lights to cut carbon emissions.B.A company uses coal more efficiently to reduce waste.C.A family saves money by using energysaving devices.D.A lady spends savings from her fuel efficient car on more clothes.5.How did Paul Brockways team carry
14、 out their research?A.By interviewing economists.B.By analyzing former studies.C.By modeling the rebound effect.D.By debating about the Jevons paradox.6.What would Paul Brockway probably agree with?A.Authorities should dismiss energy efficiency.B.Worldwide efforts to preserve energy are in vain.C.Th
15、e rebound effect helps protect the environment.D.More attention should be paid to the rebound effect.7.Whats the authors attitude towards limiting the rebound effect?A.Positive.B.Pessimistic.C.Doubtful.D.Disapproving.C Thermoelectric generators turn waste heat into electricity without producing gree
16、nhouse gas emissions,like a free lunch.But the high cost of these devices has prevented their widespread use.Now,researchers have found a way to make cheap thermae-lectrices that work just as well.The work could pave the way for greener car engines,and other energy-generating devices.“This looks lik
17、e a very smart way to realize high performance,”says Li-Dong Zhao,a materials scientist.He notes there are still a few more steps before these materials can become high-performing.However,he says,“This will be used in the not too far future.”Thermoelectrics are semiconductor devices placed on a hot
18、surface.That gives them a hot side and a cool side.If a device allows the hot side to warm up the cool side,the electricity stops flowing.A devices success at preventing this,as well as its ability to conduct electrons,feeds into a score known as the figure of merit,or ZT.Researchers have produced t
19、hermoelectric materials with increasing ZTs.The record came in 2014 when Mercouri Kanatzidis came up with a tin selenide with a ZT of 3.1.Yet the material was too fragile to work with.“For practical applications,its a non-star-ter,”Kanatzidis says.Getting through that door will still take some time.
20、The tin selenide the team makes is mixed with Na,creating a“p-type”material that conducts positive charges.To make working devices,researchers also need an“n-type”version to conduct negative charges.Zhaos team is now working on making an n-type version.Once successful,researchers should have a clear
21、 path to making a new generation of super-efficient thermoelectric genera-tors.Those could be installed everywhere from automobile exhaust pipes to water heaters and industrial smelters toscavengesome of the 65%of fossil fuel energy that winds up as waste heat.8.The first paragraph wants to tell us_
22、.A.The wide use of thermoelectric generators B.The devices of current thermoelectric generators C.The reason why researchers make cheap thermoelectrics D.The greener car engines that contribute to environmental protection 9.How does Li-Dong Zhao feel about cheap thermoelectric generators?A.Indiffere
23、nt.B.Optimistic.C.Critical.D.Worried.10.What do you know about the research in 2014 from paragraph 4 and 5?A.It was far from a success for practical applications.B.A tin selenide with a ZT of 3.1 can be easy to work with.C.Researchers made an“n-type”version to make working devices D.A“p-type”materia
24、l made from the tin selenide conducts negative charges 11.What does the underlined word“scavenge”in the last paragraph mean?A.Recycle.B.Produce.C.Clean.D.Increase.D One-year-old Tallulah turned purple and stopped moving after the sweet became stuck in her throat.Her mum Leigh-Anne said the drama beg
