8、sabilities were “of no use” and therefore,better off dead.Fortunately,Srikanths parents loved their son and refused to give him up.Instead,they encouraged the blind boy to dream big and reach for the stars.Srikanth did not disappoint his parents.The now twenty-seven-year-old is the founder and CEO o
9、f Bollant Industries.Of course,getting here was not easy.Being both blind and poor meant that Srikanth had to face hard challenges.As a young boy,Srikanth attended a regular school near his home.Unfortunately,the students and teachers didnt quite like him because of his disability.As a result,the yo
10、ung boy was largely ignored and often spent the entire day alone.Concerned this would hold back Srikanths development,his family decided to send him to a special school in Hyderabad.Sure enough,the young boy soon rose to the top of his class,winning awards in speech and debate competitions.But Srika
11、nth was prevented from studying sciences when he reached the 10th grade,because it was thought too “dangerous” for a blind student.Not wanting to give up,Srikanth took legal action and became the first blind student in the country allowed to study sciences.Later,after graduating from the Massachuset
12、ts Institute of Technology,Srikanth set up Bollant Industries in 2012.For just four years,it became a powerhouse with over 450 employees,70% of whom are physically challenged.Being disabled doesnt mean being unable.“If the world looks at me and says,Srikanth,you can do nothing. I will look back at t
13、he world and say,I can do anything.” the young man says.4.Why was Srikanth sent to a special school?A.His parents became richer than before.B.He could be treated equally there.C.This school was free for disabled students.D.He was sent away by the regular school.5.What can we know about Srikanth from

15、orn.7.What can be the best title for the text?A.Chances Are EverywhereB.No Challenges,No SuccessC.A Big Dream Makes a DifferenceD.Disability Doesnt Mean Being UnableCSeveral years ago,when someone used camera covers to protect against possible monitoring,it was not popular to talk about it.Today,peo
16、ple use various types of tapes to cover the web cameras and microphones.There are many types of spyware that can dive into our devices and secretly spy on them,recording everything they do.Such programs may infect not only computers but also smartphones.Your data may be used by hackers who will try
17、to request money for not exposing your private information or by companies like NSO Group who created the Pegasus spyware to “provide authorized governments with technology that helps struggle against terror and crime”.In my opinion,the described protection technique is highly overestimated.Users ta
18、pe cameras and microphones due to the lack of understanding of how their devices work and how malware(恶意软件) works.Hackers and even secret services do not have enough resources to monitor all victims using cameras or microphones.If they need to get any information,they get it by sending a targeted ma
19、lware to your device,which will not be stopped by the tapes.Such a virus will find what to stealfrom personal photos and videos to passwords from social networks,browser history,bank accounts and much more.It is unwise to believe that attackers will not be able to find a way to spy on you,even if th
20、e device,discharged to zero,can still deliver data about your location,using the smartphones of the surrounding people as signal repeaters.Let us face it:we live in an era when it is extremely difficult to hide something and a piece of tape is clearly not the most useful tool in the struggle for you
21、r privacy.Again,to be able to spy on you,attackers need to plant malware in your device.To prevent malware from entering your device,do not click suspected links and email attachments.Use strong passwords for email,social media and online banking accounts.8.What does the underlined word “them” in pa
22、ragraph 2 refer to?A.Cameras.B.Types.C.Programs.D.Devices.9.What is NSO Group?A.A group of hackers.B.A company developing spyware.C.A group of terrorists and criminals.D.A company fighting against crime.10.Why does the author think “the described protection technique is highly overestimated”?A.Peopl

24、cking distrustful links.DWhich is better for Earth:an electric or gas-powered vehicle?The answer to this question might seem blindingly obvious:Of course electric cars must be better for the environment,because they dont give off greenhouse gases as people drive.However,electric vehicles(EVs) arent
25、perfect,and they come with their own set of polluting problems.Their batteries require a large amount of energy to produce.Battery production is just one part of an electric cars life span.A study looked at the entire life cycle of an EVs emissions(排放),from mining the metals for the batteries to pro
26、ducing the electricity needed to power them,and then compared this with the average emissions of a gas-powered vehicle.The team found that when EVs are charged with coal-powered electricity,theyre actually worse for the environment than gas-powered cars.“Only when connected to the dirtiest,coal-heav
27、y electric grids(电网) do gas-powered cars become comparable to EVs on a greenhouse gas basis,” said Colin Sheppard,an expert in energy and transportation systems.Thats why more and more countries are decreasing the power supply from coal.In China,the national grid is improving with more investments i
28、n renewable energy.For example,it has twice as much wind energy capacity as the U.S.and it builds more solar panels per year than any other countries.Sheppard modelled a future in which all cars were electric.“We wanted to understand what it might be like if all passenger vehicles are electrified.”
29、For example,Sheppard calculated that if all vehicles in the U.S.were electric,it would reduce greenhouse-gas emissions by 46% every year.This reduction could be increased even further if those vehicles were using a technique known as“smart charging” in which cars are recharged at chosen times(often
30、at night) to reduce the cost of electricity.In short,its far easier to argue in favor of buying an EV than a gas-powered vehicle.But what about the cost?Arent electric vehicles too expensive for most people?12.In which case do EVs get more heavy-polluted than gas-powered cars?A.Being powered only by
31、 batteries.B.Consuming coal-powered electricity.C.Starting to give off greenhouse gases.D.Replacing gas-powered vehicles entirely.13.What is greatly promoted in China now according to the text?A.Renewable energy.B.Electric vehicles.C.Coal-powered supply.D.Public transport.14.How does Sheppard model
32、the future of EVs?A.With a discussion.B.With an examination.C.With a calculation.D.With a questionaire.15.What might the paragraph following the passage be about?A.Inventing green gas-powered vehicles.B.Developing environment-friendly grids.C.Making electric vehicles more affordable.D.Getting rid of
33、 fossil energy like coal and oil.第二节(共5小题;每小题2.5分,满分12.5分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。How to Succeed in ScienceTo succeed in science,you need a lot more than luck.In my view,you have to combine intelligence with a willingness not to follow conventions when they block your forward path.
34、Thus,these have come to be my rules for success.16That might sound proud,but the fact is that you must always turn to people who are brighter than you.Its like playing any game.Even as a child,I never wanted to play games with anyone who was as bad as I was.If you win,it gives you no pleasure.And in
35、 the game of science or life,the highest goal isnt simply to win;its to win at something really difficult.17Take risks.To make a huge success,a scientist has to be prepared to get into deep trouble.If you are going to make a huge jump in science,you will very likely be unqualified to succeed by defi
36、nition.18 This can be more than personally upsetting.Never do anything that bores you.My experience in science is that someone is always telling you to do things,and then leaves you alone.Im not good enough to do well in something I dislike.19Its very hard to succeed if you dont want to be with othe
37、r scientists,because you have to go to key meetings where you spot key facts that would have escaped you.And you have to chat with your competitors,even if you find them objectionable.So my final rule is:20A.Meet challenges with great courage.B.If you cant stand being with your real peers,get out of
38、 science.C.Put it another way,its to go somewhere beyond your ability and come out on top.D.Make sure you always have someone to save you from a deep mess.E.Avoid foolish people.F.In fact,I find it hard to do well in something I like.G.Besides,you even have to be prepared to disbelieve your scientif
39、ic heroes.第二部分语言运用(共两节,满分30分)第一节(共15小题;每小题1分,满分15分)阅读下面短文,从每题所给的A、B、C、D四个选项中选出可以填入空白处的最佳选项。She is over a century old,but she hasnt let that stop her from working.At 102,Romay Davis 21 drives herself to the grocery store each day for 22.Now,during Black History Month,Davis is being honored for her 23
