参考解析

解析:本题考查的是态度分析。
【关键词】attitude;touch ID technology on iPhone X
【主题句】“If a password is compromised, it can be changed—but a face cannot be changed.” ”如果密码被盗用,可以改密码——但是人脸无法改变。”
【解析】选项A意为“有前途的”;选项B意为“怀疑”;选项C意为“支持”;选项D意为“中立”。文章开篇即提出iPhone X的FaceID是否能在各种条件下正常使用这样一个疑问;第二段进行让步说了该手机人脸识别技术的先进性;第三段又转折回到正题——对FaceID是否能在不同条件下正常使用不确定;第四段对“it is not clear how often FaceID fails to recognize its owner”这样一个问题没有答案;最后一段又提出其存在一个撤销的问题。总体看来,作者对iPhone X新技术的态度已经很明显,应该是怀疑的。另外,通过文中的一些字眼,如claim, show off, does sound promising等也可以推断出作者的态度。

Part II Reading Comprehension (40 points) Directions: There are four passages in this part. Each passage is followed by five questions or statements. Choose the best answer to each question or decide T/F for each statement. Passage One People often say that the Englishman's home is his castle. They mean that the home is very important and personal. Most people in Britain live in houses rather than flats, and many people own their homes. This means that they can make them personal, and change them in any way they like- Most houses have a garden, even if it is a small one, and the garden is usually loved. The house and the garden are the private space of a person. In a crowded city a person knows that he or she has a private space which is only for him or herself and for invited friends. People usually like to mark their space. If you are on the beach you may have spread your towels around you; on the train you may have put your coat or small bag on the seat beside you; in a library you may spread your books around you. Once I was travelling on a train to London. I was in a section for four people and there was a table between us. The man opposite to me had his briefcase on the table. There was no space on my side of the table at all. I was unhappy. I thought he thought that he owned the whole table. I had been reading a book about nonverbal communication, so I took various papers out of my bag and put them on his case! When I did this he suddenly became angry and his eyes nearly popped out of his head. I had taken up his space! A few minutes later I took my papers off in order to read them. He immediately moved his case to his side of the table.(1).The home matters greatly to Englishmen.A.TB.F(2).They love houses more than gardens.A.TB.F(3).person often likes to use something to mark his / her space belonging to himself / herself.A.TB.F(4).On the train to London, the man beside the writer placed his briefcase on the table.A.TB.F(5).The writer tried to get back his space by taking all his papers out.A.TB.F

Interviews are part of most people' s working life. Here are some handy tips on how to do your best at interviews. Interviews are part of most people s working life. Here are some handy tips on how to do your best at interviews.Don t mistakenly think that your interviewers want to know about you. They are interested only in that small part of you that can or can t do the job they have advertised.sadly , many of us are so flattered by questions such as Tell me about your strengths that we take it as an invitation to chatter and make fools of ourselves.Never think that lots of enthusiasm is enough. sit down with a pen , paper and the job description ,and work out the skills and qualities they are looking for.Itemize your technical or professional skills as they match the requirements of the job. Then recall an incident to illustrate each of these skills. When you have done this, you will be in a position to begin justifying your ability and suitability.Remember that very few questions are lightly asked.If your interviewers are interviewing more than a couple of candidates , they have probably worked up a list of eight to ten questions to put to each person. In well-organized businesses , they will be making marks in their notebooks as you give your replies. An imprecise answer will show that you do not appreciate the value of the question. s0 think through how you can give strong, specific answers to questions such as Can you work well in a team or on your own or in a small business?Avoid giving them reasons to exclude you. You want to appear the sort of person who will help out in a crisis. make the tea sometimes even if it is not your job. be tolerant of others. whatever their age ,sex , race or religion ,and be easy to manage. Dont attack your previous employer as it suggests you might attack your now one.Try asking them a few questions. If you ask what sort of projects you would be likely to start work on ,you might then get back some very useful feedback.

But at about age 15 0r so, the men voluntarily began cutting clown their nightly sleep time because of pressures from school, work, and other activities. These men tended to view their nightly periods of unconsciousness as bothersome interruptions in their daily routines.In general, these“short sleepers”appeared ambitious, active, energetic, cheerful,conformist in their opinions, and very sure about their career choices. They often heldseveral jobs at once, or work full-or part-time while going to school. And many of them hada strong urge to appear “normal”or “acceptable” to their friends and associates , When asked to recall their dreams, the “short sleepers”did poorly. More than this,they seemed to prefer not remembering. In similar fashion, their usual way of dealing with psychological problems was to deny that the problem existed, and then to keep busy in the hope that the trouble woula go away.The sleep patterns of the “short sleepers” were similar to, but less extreme than, sleep patterns shown by many mental patients categorized as manic.The“long sleepers”were quite different indeed. According to the study, these young men had lengthy sleeps since childhood. They seemed to enjoy their sleep, protected it, and were quite concerned when they were occasionally deprived of their desired 9 hours of nightly bed rest. They tended to recall their dreams much better than did the “short sleepers”。Many of the“long sleepers” were shy, anxious, introverted, inhibited, passive, mildly depressed, and unsure of themselves (particularly in social situations). Several openly state that sleep was an escape from their daily problems.According to the study, ( ).A. many short sleepers need less sleep by natureB. many short sleepers are obliged to reduce their nightly sleep time because they are busy with their workC. long sleepers sleep a longer period of time during the dayD. many long sleepers preserve their sleeping habit formed during their childhood

Left in a bank it will hardly keep its value, however high the interest rate is.Only a brave man, or a very rich one, dares to buy and sell on the Stock Market.Today it seems that one of the best ways to protect your savings, and even increase your wealth is to buy beautiful objects from the past.Here I am going to offer some advice on collecting antique clocks, which I personally consider are among the most interesting of antiques.I sometimes woncler wl:cat a being from another planet might report back about our wayof life. “The planet Earth is ruled by a mysterious creature that sits or stands in a room and makes a strange ticking sound. It has a face with twelve black marks and two hands. Men can do nothing without its permission, and it fastens its young round people's wrists so that everywhere men go they are still under its control.This creature is the real master of Earth and men are its slaves. ”Whether or not we are slaves of time today depends on our culture and personality, but it is believed that many years ago kings kept special slaves to tell the time. Certain men were very clever at measuring the time of day according to the beating of their own hearts. They were made to stand in a fixed place and every hour or so would shout the time. So it seems that the first clocks were human beings.However, men quickly found more convenient and reliable ways of telling the time.They learned to use the shadows cast by the sun.They marked the hours on candles, used sand in hour-glasses, and invented water-clocks.Indeed, any serious student of antiques should spend as much time as possible visiting palaces, stately homes and museums to see some of the finest examples of clocks from the past.Antique clocks could be very expensive, but one of the joys of collecting clocks is that it is still possible to find quite cheap ones for your own home. After all, if you are going to be ruled by the time, why not invest in air antique clock and perhaps make a future profit?According to the passage, collecting antique clocks ( ).A. can hardly keep the value of your savingsB. will cost much of your moneyC. may increase your wealthD. needs your bravery

Not a lot of men among that group, are there?Yet some of those jobs are really important.Surely no one would deny that about nurses and teachers, for a start.So why do we reward the people who do them so poorly? There can be only one answer—because they are women.This is not going to be put right overnight. But the Government which employs a lot of them, and other bosses have to make a start.It is disgraceful(可耻的) that we have gone into the 21st century but still treat women as second-class citizens.Women should have the chance of doing the same jobs and be paid equally as Men( ).A. after 25 yearsB. according to the lawC. as a result of the Equal Pay ActD. because women are as strong as men

Instead both men opened bookshops on opposite sides of Coleford High Street. It was hard to make money from books, which made the competition between them worse.Then Richard married a mysterious girl. The couple spent their honeymoon on the coast—but Richard never came back. The police found his wallet on a deserted beach but the body was never found. He must have drowned.Now with only one bookshop in town, business was better for George. But sometimes he sat in his narrow, old kitchen and gazed out of the dirty window, thinking about his formal rival(竞争对手). Perhaps he missed him?George was very interested in old dictionaries. He’d recently found a collector in Australia who was selling a rare first edition. When the parcel arrived, the book was in perfect condition and George was delighted. But while he was having lunch, George glanced at the photo in the newspaper that the book had been wrapped in. He was astonished—the smiling face was older than he remembered but unmistakable! Trembling, George started reading.“Bookends have bought ten bookstores from their rivals Dylans. The company, owned by multi-millionaire Richard Pike, is now the largest bookseller in Australia.”65. George and Richard were ______ at school.A. roommates B. good friends C. competitors D. booksellers

For each of them there are four choices , You should decide on the best choice.Your face is the future of smartphone security. Apple made that clear last week when it unveiled the pricey iPhone X. Apple claims to have conquered many of the challenges that have prevented the widespread use offacial biometrics. But a number of computer-vision researchers say they are skeptical that a smartphone-based system like FaceID can account for things like variable lighting conditions or subtle changes in a person's appearance to create a secure-yet-practical way to unlock a phone a dozen or more times a day.Apple’s new technology does sound promising. The company says FaceID creates a “precise depth map” of one’s visage by projecting more than 30,000 infrared dots against a person’s face, then using the phone’s infrared TrueDepth camera and high-power microchip to collect and analyze the results. Users are also asked to turn their head as they scan so the phone's machine-learning algorithm can measure the face from several angles and create a more detailed 3-D map of their features. Once the map is created and stored, the iPhone X uses infrared light to help FaceID scan a person’s face even in the dark. Meanwhile, machine-learning algorithms running on the phonekeep track of changes in a person's appearance—including glasses, facial hair and hats—so the smartphone’s accuracy improves over time.Despite advances in facial recognition in recent years, it remains unclear whether FaceID will work in a variety of conditions while also keeping the iPhone X secure. Hackers, for example, quickly found a way to bypass the Samsung Galaxy S8's facial-recognition scanner when it was introduced in March: They tricked the device by simply showing it a photo of the user. FaceID’s use of 3-D facial maps could address that problem. But historically it has been a big challenge for such a system to recognize faces under different lighting conditions and from a variety of angles.Apple showed off FaceID last week under relatively controlled conditions, says Arun Ross, a professor of computer science and engineering at Michigan State University. Clearly the demo was very interesting, he says. But at the same time some extraordinary claims were made. Apple' s Schiller said, for example, that the chance a random person' s face could unlock someone else' s iPhone X was one in a million——much more secure than TouchID. Ross says, however, that it is not clear how often FaceID fails to recognize its owner. When contacted, Apple declined to elaborate on Schiller' s comments.“Like all biometrics, FaceID will have a problem with revocation,” says Vitaly Shmatikov, a computer science professor at Cornell Tech. “If a password is compromised, it can be changed—but a face cannot be changed.” Apple touts its ability to secure data on its iPhones, which do not share biometric information with the company’s servers. Still, Ross says, hackers always seem to find a way around even the tightest security.What does Arun Ross mean by “relatively controlled condition”?A.To start an explanation of FaceID' s using condition.B.To mention that Apple Inc. shows their new product under a well designed environment.C.To imply that FaceID has its limits.D.To add a context explanation of the interesting demo.
