But if the salary is good, we 1 put up with it. However, if you unfortunately have a very difficult boss, then it is 2 story. Sometimes, you do come across that kind of boss who keeps giving verbal consent , but never taking the commitment seriously.You may have already met this kind of boss. At first they agreed to let you push forward a new project, then somehow they changed their minds and acted 3 they had neveragreed to it. Or, your boss may never fulfill what he 4 (promise) you and stop mentioning it at all.Such a boss can turn a good working environment into 5 uncomfortable and unhappy workplace. But he is the boss. He has the power to assign tasks and ultimately fire us. This power imbalance is why we should struggle to figure out a way out.Tip 1: Figure out why.Some bosses might be forgetful while others might receive benefits to which they 6 (entitle) and see you a threat, in which case you must know how to defend yourself. 7 (talk) to your boss the problems in a humble, polite and professional manner can help you solve the problem.Tip 2: Make full preparations.At each important point, confirm with them the 8 (agree) things, keep them updated 9_____ the progress, then confirm the direction again, and wait for them to give a new promisebefore you continue.Tip 3: Speak up in the public.It is best not to talk with your boss in private, but let some other colleagues participate in the conversation.For example, if you communicate in emails, you may copy it to all the people involved. If it is a verbal communication, then you may choose somewhere someone else is present ___10_____(have) the conversation.Section B (10%)Directions: Fill in each blanks with a proper word chosen from the box.

For an industrial economy that has built its global name on its reputation for quality, these are nerve-racking times.No one thought that Japanese companies were basically more honest than their counterparts around the world, says one former Toshiba executive, but there was an assumption both inside and outside Japan that everyone on the factory floor was devoted to the perfection of monzoukuri, the craftsmanship that represents what is arguably the 8 of Japanese corporate boasts. “That9is what has taken the heaviest beating,” he said.When Hiroya Kawasaki, the chief executive of Kobe Steel, first 10 that the company had been taking part in data falsification that dated back to the 1970s, his statement was almost apocalyptic (灾难性的)：“Trust in our company has fallen to Zero,”he said.Ⅲ.Reading comprehension.Section A (15%)Directions: For each blank in the following passage there are four words or phrases marked A, B, C, D. Fill in each blank with the word or phrase that best fits the context.A baby born in west today will more likely than not live to be 105, write Lynda Gratton and Andrew Scott of London Business School in their book, The 100-Year Life. That may sound like science fiction. 1 , it’s only cautiously optimistic.If turning 100 becomes normal, then the authors predict “a fundamental redesign of life”. We currently live “t he three-stage life”: education, career, then retirement.T he book 2 thatif today’s children want to retire on livable pensions, they will need to work until about age 80. That would be a 3 to the past: in 1880, nearly half of 80-year-old Americans did some kind of work.But few people will be able to bear the 4 and tedium of a 55-year career in a single sector. Anyway, technological changes would make their education obsolete long before they reached 80. The new life-path will 5 have more than three stages.Two new life-stages appeared in the past century: teenagers and retirees. Now another stage is 6, say Gratton and Scott: the years from 18 to 30, which people increasingly spend 7 from education to full-time work. Of course, many of today’s young have no choice: they simply cannot find good jobs. But the 18-to-30s have also been 8 to understand the gift of extrayears, say the authors. Many young people are now consciously searching and experimenting,9how they want to spend the next seven or so decades.The authors predict that more will do two degrees: first a general undergraduate course, which teaches thinking skills with lifelong value, and then a more 10 vocational degree that teaches a specific sector’s current needs. After studying, the young will spend time travelling, exploring different sectors, and11 a “posse” of friends and acquaintances who can sustain them at work and outside for 70 years.Future careers will contain many transformations. People will have to make more 12 : next year, should you work hard in your job, return to education, or transition to an entirely new sector? There will be time to achieve 13 in multiple domains. No longer will women be 14 careers because they took five or 10 years out to raise kids. That will still leave them 50-plus working years.And people will change their use of leisure. When you could expect a 40-year career followed by fat state or corporate pensions, you could spend your free time chilling and buying stuff. But the 100-year life15 more saving. You might also need to spend much of your non-working time reskilling or exercising to maintain your body and brain for those extra decades.1. A. In particular B. In fact C. At least D.

Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D Choose the one that fits best according to the information given in the passage you have just read.AYoung people are losing faith in an elitist education system. “If you don’t have the ability then blame your parents,” wrote Jung Yoo-ra on social media in 2014, after being accepted into a famous university. Her mother, it turns out, had gone to great lengths to secure a spot for her, persuading Ehwa Women’s University to alter its admissions policy in a manner tailor-made for Ms. Jung.Last month a court ruled that the nine people involved in this deception had fundamentally shaken the “values of fairness of our society”. Above all, the “feelings of emptiness and betrayal they caused in hardworking students” could not be excused.University was once seen as a source of social mobility in South Korea. But so important is the right degree to a student’s prospects in life that rich families began spending heavily on coaching to improve their children’s chances, leaving poorer families behind.By 2007 over three-quarters of students were receiving some form of private tuition, maximizing the three necessities to win a place at a good university: “father’s wealth, mother’s information, child’s diligence”.Many South Koreans believe that the rich and influential do not just spend more on education, they also manipulate the system, as Ms. Jung’s mother, a close friend of the previous president, did so spectacularly.According to the Pew Research Centre, a think-tank, only a fifth of those aged 18-33 believe that working hard brings success.An ever-growing dictionary of slang proves the perception: people speak of using “back” (backing, or connections) to get jobs; when Ms. Jung refused to return to South Korea to face charges rela ted to her university admission, the local press described it as a “gold-spoon escape”.1.It can be inferred from the article that JungA.was admitted into the university without the slightest effort.B.believed children's prospect was determined by their parents' capability.C.was spared a legal punishment because of her connection.D.held a strong belief in social mobility in Korea.2.The feeling of betrayal and emptiness comes fromA.Ms. Jung’s ignorance in the university admissionB.their lack of resources to support their childrenC.the decline in the elite education systemD.the loss of education equality and social mobility opportunity3.Why do only a few people stick to the belief that success comes from hard work?A.The purse of their parents is a determining factor in success.B.They feel inferior to their rich peers.C.Rich people take great pains in the educating their childrenD.The good-spoon escape has shaken their value.BSure, your family and friends may think you've lost your marbles when you announce plans for a midlife career change, but take heart. There are a number of considerations that go into a successful career change.1.Making a rash decisionBefore changing occupations, you should do a deep dive to assess why you want to leave your current one. Ask yourself why you're unhappy—and answer honestly. You may simply be having a bad week or a bad month—or you may just hate your boss, not your industry. "We all go through phases of unhappiness with our jobs," says Randy Block, an executive coach and staffing consultant. "You should be running toward something, not running away from something."2.Choosing a new career based on salaryYou obviously need to be financially strategic when choosing your next career, but don't base your decision solely on earning potential. "If you take a high-paying job that doesn't match your interests, values, or strengths, you're not going to be happy," says Holly Genser. Maybe at first, but the novelty will likely wear off sooner than later.3.Not researching the job market in your next fieldNot sure what field you want to go into? Research industries and positions to find a good match for your skills and career goals, Genser says. Otherwise, you're throwing darts in the dark.4.Quitting without having another job lined upResearch shows it's easier to get a job offer when you're still employed, which makes sense since gaps on a resume might make a hiring manager think twice about calling you in for an interview. Consequently, it's in your best interest to stay at your current job until you have your next one set up.1.Which of the following is correct according to the passage?A.If you can't get along well with your boss, it's better to change your job.B.Show disregard to salary when evaluating the job optionsC.You may stick to the current job until a new opportunity shows up.D -Going back to the school may increase the job prospect.2.What does the underli ned word “throw darts in the dark” mean?(para 4 line 2)A, "make an attempt with little chance of success.B.waste your skills and experience.C.overshadow others in the competition.D.-lose yourself in the interview3.Which of the following might be the guiding principle of the writer in job-hopping?A.Enjoy the pleasure of life here and now.B.Success is favored by the people who are fully preparedC.Greed is the most real poverty, satisfaction the most real wealth.D.Nurture is above nature.4.Where does the passage probably come from?A. Career Orientation MagazineB. Tourism Leaflet.C. Family Counselling Brochure D: Graduation Advisory LectureCGoogle has been hit with a class-action lawsuit alleging discrimination against conservative- minded white men, in a legal case that threatens a fresh round of the culture wars that engulfed the internet company last summer.The suit has been brought by James Dam ore, an engineer who was sacked in August after his questioning of Google policies to increase the hiring of women and minorities caused an outcry inside the company. It also names a second engineer, David Demanding, who has also claimed wrongful termination after leaving the company in 2016. The company did not immediately have a response to the suit.Since leaving Google, Mr Dam ore has spoken out widely against the company, attacking it for what he calls “group think” over gender and other diversity issues. His case became a rallying point for conservatives last year at a time when cultural battles stirred by President Donald Trump were intensifying nationally.The class action lawsuit, filed in superior court in California on Monday, was brought on behalf of all employees whom Google is alleged to have discriminated against either because of “their perceived conservative political views . . . their male gender . . . [or] their Caucasian race”.The lawsuit claims that there is “open hostility for conservative thought” at the company and that people who diverge from the mainstream are singled out for expressing views on subjects such as diversity hiring policies, bias sensitivity and social justice.Employees are “distracted, belittled and punished for their heterodox political views, and for the added sin of their birth circumstances of being Caucasians and/or males”, the suit alleges. It accuses Google of being an “ideological echo chamber” that is hostile to some workers, and of maintaining illegal hiring quotas for women and minorities. The suit will move forward only if a judge certifies it as a valid action on behalf of an entire class of workers.Mr Dam ore was dismissed by Sundae Archaic, Google’s chief executive, after writing an internal memo questioning the company’s di versity policies. His paper was widely circulated and aroused a backlash inside Google. But his treatment brought an outcry from conservatives who saw Mr Pharisaic reaction as an attack on open discussion of an important social issue.Among the allegations, the lawsuit claims that “the presence of Caucasians and males wasmocked with ‘boos’ during company-wide weekly meetings” at Google.1.James Damore was fired by Google on the grounds thatA.he embraced the vision that women were underemployed in GoogleB.he found it hard to adapt himself to the corporate culture of GoogleC.Google is intolerable of different viewpoints of employees on Sex/puffD.he expressed the sexist attitude towards women’s professional fulfillment2.Which of the f ollowing CAN’T explain Google’s being adder fire by JamesDamore?A.The code of conduct and basic values of Google does harm to some employees.B.Google attached no importance to female fulfillment.C.Google weeded out discrimination rather than take a permissive approach.D.white people were underrated and blamed for their so-called ethnic politicalOpinions.3.What does the underlined phrase probably mean?A. resistance B sympathy C. affectation. D indifference4.The passage is chiefly concerned withA.arguing against a reversed discrimination from a dismissed Google employeeB.warning the application of Google value affecting the employees negativelyC.advocating the same treatment in workplaceD.exploring the legal remedies for inequality among workersSection CDirections: complete the following passage by using the sentence given below. Each sentence can be used only once. Note that there are two more sentences than you need.A.Such flowery writing would deserve to be pulled out by the roots.B.They keep a continuous check on advertising.C.They misrepresent the products they are advertising.D.What does the ASA do to advertisers who deceive the p ublic?E.What makes an advertisement misleading?F.For this to be believable, the ASA h as to be totally independent of the business.The Advertising Standards Authority: An Advertising Watchdog Do adventurists sometimes distort the truth? The short answer is yes, some do. Nearly all of them play fair with the people they are addressed to. But a handful do not.1 The function of the Advertising Standard Authority (ASA)is to make sure these ads are found and stopped. 2If a physical training course had turn a 45-kilogram weakling into a strong man, the fact could be advertised because it can be proved. But a promise to build ‘you’ into a 95-kilogram he-man would be misleading because the promise could not always be kept.‘Make you look younger’ might be a reasonable claim for a cosmetic. But promising to ‘take years off your life’ would be an counterclaim similar to a promise of eternal youth.A garden center’s claim that its seedlings would produce ‘a bright show of colour in just a few days’ might be quite contrary to the reality.3Why it’s a two-way process?Because of the large amount of advertisements, the ASA cannot watch over every advertiser all the time. So the public is encouraged to help by reporting about advertisements they ought not to have appeared. Last year 7500 people wrote to ASA.Whose interests does the ASA really reflect?The Advertising Standards Authority was not created by law and was no legal powers, so not unnaturally some people are skeptical about its effectiveness. In fact the ASA was set up by the advertising business to make sure the system of self-control worked in the public’s interest.4 Neither the chairman nor the majority of the ASA council members is allowed to have anything to do with advertising. Thought the ASA uses influence over the ASA decisions.Ⅳ. Summary Writing (10%)Directions: Read the following passage. Summarize in no more than 60 words the main idea and the main point(s) of the passage and how it is illustrated. Use your own words as far as possible.What keeps us healthy and happy as we go through life? If you were going to invest now in your future best self, where would you put your time and your energy?The Harvard Study of Adult Developmentmay be the longest study of adult life that's ever been done. After 75 years of study, we’ve learned three big lessons about relationships.The first is that social connections are really good for us, and that loneliness kills. It turns out that people who are more socially connected to family, to friends, to community, are happier, they're physically healthier, and they live longer than people who are less well connected. And the experience of loneliness turns out to be harmful. People who are more isolated than they want to be from others find that they are less happy, their health declines earlier in midlife, their brain functioning declines sooner and they live shorter lives than people who are not lonely.And we know that you can be lonely in a crowd and you can be lonely in a marriage, so the second big lesson that we learned is that it's not just the number of friends you have, and it's not whether or not you're in a committed relationship, but it's the quality of your close relationships that matters. It turns out that living in the midst of conflict is really bad for our health. High-conflict marriages, for example, without much affection, turn out to be very bad for our health, perhaps worse than getting divorced. And living in the midst of good, warm relationships is protective.And the third big lesson that we learned about relationships and our health is that good relationships don't just protect our bodies, they protect our brains. It turns out that being in a securely attached relationship to another person in your 80s is protective, that the people who are in relationships where they really feel they can count on the other person in times of need, those people's memories stay sharper longer. And the people in relationships where they feel they really can't count on the other one, those are the people who experience earlier memory decline. And those good relationships, they don't have to be smooth all the time. Some of our octogenarian couples could bicker with each other day in and day out, but as long as they felt that they could really count on the other when the going got tough, those arguments didn't take a toll on their memories.So the clearest message that we get from this 75-year study is this: Good relationships keep us happier and healthier.Ⅴ.
