1、一、阅读理解一、阅读理解Many leading AI researchers think that in a matter of decades, artificial intelligence will be able to donot merely some of our jobs, but all of our jobs, forever transforming life on the earth.The reason why many people regard this as science fiction is that weve traditionally thought o
2、fintelligence as something mysterious that can only exist in biological organisms, especially humans. Butsuch an idea is unscientific.From my point of view as a physicist and AI researcher, intelligence is simply a certain kind ofinformation processing performed by elementary particles (基本粒子) moving
3、 around, and there is no lawof physics that says one cant build more intelligent machines than us in all ways. This suggests that weveonly seen the tip of the iceberg and that there is the amazing potential to unlock the full intelligence thatexists in nature and use it to help humanity.If we get it
4、 right, the upside is huge. Since everything we love about civilization is the product ofintelligence, amplifying our own intelligence with AI has the potential to solve tomorrows toughestproblems. For example, why risk our loved ones dying in traffic accidents that self-driving cars couldprevent or
5、 dying of cancers that AI might help us find cures for? Why not increase productivity throughautomation and use AI to accelerate our research and development of affordable sustainable(可持续的)energy?Im optimistic that we can develop rapidly with advanced AI as long as we win the race between thegrowing
6、 power of our technology and the knowledge with which we manage it. But this requires giving upour outdated concept of learning from mistakes. That helped us win the race with less powerful technology.We met with fire and then invented fire extinguishers (灭火器), and we met with cars and then invented
7、seat belts. However, its an awful idea for more powerful technologies, such as nuclear weapons or superintelligent AIwhere even a single mistake is unacceptable and we need to get things right from the first.1.How do many people feel about leading AI researchers predictions?A.Worried.B.Curious.C.Dou
8、btful.D.Disappointed.2.What does the author think of intelligence?A.We know little about it.B.It belongs to human beings.C.It is too difficult to understand.D.We have a good command of it.3.What does the underlined word upside in Paragraph 4 probably mean?A.Cost.B.Potential.C.Quantity.D.Advantage.4.
9、Whats important for us in the race between people and technology?A.Learning from failure.B.Increasing our intelligence.C.Avoiding making mistakes.D.Making accurate predictions.Dogs are our best friends. Thats especially true after a disaster, such as an earthquake. When buildingsfall down, search-an
10、d-rescue dogs help find trapped people. Dogs amazing noses can pick up the smell ofsurvivors. Now scientists have developed an electronic tool that does the same thing. Its taking smelldetection(探测) to a whole new level.The new invention is a sort of electronic nose, which can detect extremely low l
11、evels of manycompounds(化合物) from peoples skin. This isnt the first time engineers have developed such an object.Earlier models, however, have been bulky and expensive. They could not detect low levels of targetcompounds either. The new one is inexpensive and small enough to fit inside hand-held equi
12、pment.The electronic nose can detect extremely slight smell of more than one compound at the same time.Being able to do this, in such a small object, is the significant discovery, says Sotiris E. Pratsinis,Professor of Process Engineering and Materials Science at the Swiss Federal Institute of Techn
13、ology inZurich. His team tested it in special spaces. They were like the small spaces where people might be trapped.Chemicals given off by the volunteers built up inside. The electronic equipment detected those compoundsat unbelievably low levels.The results were good news for the research team. But
14、 they may be not for our four-legged friends, whocould soon be out of a job. Ideally, this technology could replace search-and-rescue dogs, Pratsinis says.Stephen Taylor, an electrical engineer, agrees that the new technology has some benefits over dogs. Still,he thinks it may be too soon to have ou
15、r trusty friends retire. He suspects, I foresee that such an objectcould add to the fine work done by the dogs. Taylor also points out some potential limitations of the newinvention. E-noses are useful, but can be very likely to be affected by unstable readings and interruption,he says.1.Why does th
16、e author talk about dogs at the beginning?A.To catch the readers attention.B.To introduce the topic about e-noses.C.To show what search-and-rescue dogs do.D.To add background information for discussion.2.Which of the following best explains bulky underlined in Paragraph 2?A.Complex.B.Fragile.C.Handy
17、.D.Large.3.What is Paragraph 3 mainly about?A.What e-noses working principle is.B.How e-noses are made.C.What differences between dogs and e-noses are.D.How powerful e-noses are.4.What does Stephen Taylor mean?A.Dogs and e-noses could work together.B.Search-and-rescue dogs will retire soon.C.E-noses
18、 are more reliable than noses of dogs. D.Dogs are better at finding out trapped people.Twenty-five years ago, most young Britons wanted a career in law, to be a doctor, or, if they werecreative enough, to take up singing. But today, things stand different.According to a survey by Tesco Mobile, a UK
19、company, the dream job of young people aged between16 and 25 in the UK is a video blogger, or vlogger. The survey, carried out among 1,002 people, foundthat as many as 40 percent of them put vloggers as their number one choice on a list of ideal careers.This change is undoubtedly as a result of the
20、Internet and social media. They have made it so mucheasier to reach the audience of the world, without having to enter a career in show business in thetraditional way.In the past, the biggest stars were trained by the Hollywood studios; now, anyone with a computercamera can become a star.

For every success there are h
22、undreds ofothers who never get off the starting line. There are the dreams that come true and the dreams that remaindreams forever.Although being vloggers is popular, some young people choose to follow careers that dont necessarilyearn them fame, but that allow them to make good use of the Internet
23、to share their hobbies. Young IsraeliDavid Leshaw, for example, runs a business called the Finishers Club. Its an online platform for runners tokeep a record of their races. His job allows him to express his enthusiasm, and is always a learningexperience. And thats enough for him.1. Why do more and
24、more young Britons choose to be vloggers?A. Vloggers can earn greater fame and more money on the Internet.B. There is too much competition in the traditional show business.C. The Internet makes it convenient to enter show business.D. Anyone with a computer will surely become a star.2. What can we in
25、fer from the fifth paragraph?A. Only a few vloggers can be successful.B. A vlogger cannot earn fame or fortunes.C. Being a vlogger is not a good career.D. Dreams will come true one day.3. What do some young people like David do on the Internet?A. Learn from others.B. Become an online hit.C. Hold run
26、ning races.D. Mix jobs with hobbies.4. What is the passage mainly about?A. Most young Britons choose to be vloggers as their jobs.B. The Internet is influencing young Britons career choice.C. The Internet is taking the place of traditional studios.D. Young Britons cannot find jobs without the Intern

At the same time, life in the late 21st century will be different from that nowadays, becausemany changes will take place then, but what will
37、the changes be?_ There will be more and more people in the world and most of them will live longer than today.Computers will be much smaller and more useful, and there will be at least one in every home. _People will work fewer hours than they do now. They will have more free time for sports, watchi
38、ng TVand traveling. Traveling will be much cheaper and easier. _ More land will be used to build new towns and houses. Then there will be less room for cowsand sheep, so meat will be more expensive. Maybe no one will eat it every day. Instead they eat morevegetables and fruit. Maybe people will be h
