US writer Margaret Lee Runbeck once wrote, Happiness is not a station you arrive at, but amanner of travelling. But travelling is not always happy, at least for the buddies in the movie greenBook. The popular film won Best Picture at the 91stAcademy Awards on Feb 25.The movie was adapted from the true story of a road trip through the southern US in the early1960s. In the film, the black pianist Don Shirley hires Italian-American Tony Vallelonga todrive him to performances, but they face problems because of Shirley's skin color. Theseproblems lead them to form a special friendship.“There's something so deeply right about this movie, so true to the time,” wrote US film criticMick LaSalle. The time La Salle is talking about was between late 1870s and 1960s, a verydifferent period in US history. Many parts of the country had Jim Crow laws, which allowedracial segregation(种族隔离).These laws made life and travel dangerous for African-Americans. They couldn't use certainhotels, restaurants, or even gas stations. They had to be indoors after sunset or they might goto jail. Even black celebrities had to follow the laws.But in 1936, a black postman named Victor H. Green made a list of friendly businesses inNew York City. He published the list as a small book with a green cover. The Green Bookhelped African-Americans travel more safely. Then, in 1964 ,Jim Crow laws went away. Thebook went away, too.Today many US people still remember the time of Jim Crow. But they probably don’t knowabout The Green Book. It's a forgotten part of the story. Thanks to this movie,maybe peoplecan remember it again.【1】The story in the movie happened_________in the US.A.in1936 B.in the early 1960s C.In1964 D.in the late 1870s【2】According to the Jim Crow laws, African-Americans_________.A.could stay in any hotel they likeB.needn't follow the laws if they are famous peopleC.could not hang out with friends at midnightD.couldn't work with the white people【3】To help African-Americans travel more safely,_________made the Green Book.A.a black celebrity B.a black pianistC.a black postman D.an Italian-American driver【4】The film is mainly about_________.A.a dangerous and terrible trip of a pianistB.a special friendship between a pianist and a driverC.how to travel more safely in the southern USD.a different period in American history20. Shenzhen once again took part in Earth hour, as a wide range of activities were heldSaturday in Futian District to encourage people not only to switch off the lights between 8:30 p.m. and 9:30 p.m, but also to join millions in protecting biodiversity in the Guangdong- HongKong- Macao Greater Bay Area.Earth Hour, which is held annually, was started by World Wide Fund for Nature (WWF)in2007. With this year's theme, “Connect to Earth,” WWF also joined hands with One PlanetFoundation (OPF)to invite experts to conduct research on and launch an ecological map of theGreater Bay Area, in order to call attention from al1 walks of life to the promotion ofecological progress in the area. The map was officially unveiled at the 2019 Earth Hour eventat SCPG Center in Futian.In addition to this event, a carnival sharing the theme “Connect to earth”. Was organizedSaturday and Sunday at the art square in Xiangmi Park, which was open to the public for free.A representative from WWF and OPF said, “We hope this carnival, through various kinds ofactivities like games and handicrafts, will raise residents' awareness of the importance ofbiodiversity where we live. We want to engage more to protect valuable animals in the GreaterBay Area.”The two-day carnival attracted many children accompanied by their parents. A father on thescene told the Shenzhen Daily, "Interactions like this are great opportunities for kids to learnmore about the earth as they don' t get to know this knowledge very often.”Besides Shenzhen, many other cities in China also held related activities with the same focuson biodiversity but based on the local ecological habitats.【1】What's the theme of Earth Hour this year?A.Switch off the lights B.Unveil an ecological mapC.onnect to Earth D.Protect Valuable Animals【2】Earth Hour was first started by_________.A.World Wide Fund for Nature B.the Guangdong- Hong Kong-Macao Greater Bay AreaC.One planet Foundation D.SCPG Center in Futian【3】We can learn from the passage that_________.A.the carnival was held to help residents to relaxB.many other cities in China held activities with different topicsC.many parents thought the activities were helpful to childrenD.the ecological map of China was unveiled at the 2019 Earth Hour event【4】We can read this passage in the section of_________.A.Local News B.Opinion C.Market D.Business21. Whenever we watch a horror movie and something scary happens, we might close our eyesand scream. However, chances are that we'll continue to watch and enjoy the movie anyway. Sowhy can fear be so much fun?According to a recent study conducted by researchers at the University of Pittsburgh in theUS, watching horror movies can raise our mood, unite people and boost our confidence.In the study, 262 adults were asked to enter a haunted house(鬼屋)attraction. In the hauntedhouse for 35 minutes, they saw a series of tense scenes and were asked to record their feelingsboth before and after the experience. At the same time, the researchers also monitored theirbrain waves.According to the researchers, the participants were more likely to be happier and less anxiousand tired after they left the attraction. That's because in this intense condition their brainsreleased more dopamine(多巴胺), a chemical which “produce a strong feeling of excitementand happiness lasting after the threat has passed,”reported Business Insider.What's more taking advantage of this sensation may bring people together. People in scarysituations are more likely to be uncertain and depend on others for support. “We’re social andemotional beings- we need each other in times of stress,so we feel close to those we are withwhen afraid makes sense.” Said Margee Kerr,one of the study’s authors.In addition, it could be a good way to boost our confidence. “Being scared in a safe place is asource of enjoyment and makes us feel good physically and can even serve as a confidenceboost by reminding us that we can make it through a scary situation,we are strong, Kerr toldThe Independent.【1】In the study, the participants did not_________.A.stay in a haunted house for about half an hourB.record their own feelings after the experienceC.monitor their own brain wavesD.see a series of tense scenes together【2】The participants probably feel_________after they left the attraction.A.more scared B.more anxious and tiredC.less confider D.happier and more excited【3】The underlined word “boost” probably mean_________.A.lower B.reduce C.increase D.decrease【4】The purpose of the study is to find out_________.A.why people enjoy watching horror filmsB.different ways to raise mood and unite peopleC.how people feel when they are in a scary situationD.what is the source of enjoyment

({B)} Don’t Destroy the Essential Catalyst of Risk({/B)} Since the spring, and most acutely this autumn, a global contagion (传染)of fear and panic has choked off the arteries of finance, compounding a broader deterioration in the global economy. Financial institutions have an obligation to the broader financial system. We depend on a healthy, well-functioning system but we failed to raise enough questions about whether some of the trends and practices that had become commonplace really served the public’s long-term interests.({B)}Seven important lessons({/B)} As policymakers and regulators begin to consider the regulatory actions to be taken to address the fallings, I believe it is useful to reflect on some of the lessons from tiffs crisis. The first is that risk management should not be entirely predicated on historical data. In the past several months, we have heard the phrase" multiple standard deviation events" more than a few times. If events that were calculated to occur once in 20 years in fact occurred much more regularly, it does not take a mathematician to figure out that risk management assumptions did not reflect the distribution of the actual outcomes. Our industry must do more to enhance and improve scenario analysis and stress testing. Second, too many financial institutions and investors simply outsourced their risk management. Rather than undertake their own analysis, they relied on the rating agencies to do the essential work of risk analysis for them. This was true at the inception(初期)and over the period of the investment, during which time they did not consider other indicators of financial deterioration. This over-dependence on credit ratings coincided with the dilution of the desired triple A-rating. In January 2008, there were 12 triple A-rated companies in the world. At the same time, there were 64, 000 structured finance instruments, such as collateralized debt obligations, rated triple A. It is easy and appropriate to blame the rating agencies for lapses in their credit judgments. But the blame for the result is not theirs ’alone. Every financial institution that participated in the process has to accept its share of the responsibility. Third, size matters. For example, whether you owned 5 billion or 50 billion of (supposedly) low-risk super senior debt in a CDO, the likelihood of losses was, proportionally, the same. But the consequences of a miscalculation were obviously much bigger if you had a 50 billion exposure. Fourth, many risk models incorrectly assumed that positions could be fully hedged. After the collapse of Long-Term Capital Management mid the crisis in emerging markets in 1998, new products such as various basket indices and credit default swaps were created to help offset a number of risks. However, we did not, as an industry, consider carefully enough the possibility that liquidity would dry up, making it difficult to apply effective hedges. Fifth, risk models failed to capture the risk inherent in off-balance sheet activities, such as structured investment vehicles. It seems clear now that managers of companies with large off-balance sheet exposure did not appreciate the full magnitude of the economic risks they were exposed to; equally worrying, their counterparties were unaware of the full extent of these vehicles and, therefore, could not accurately assess the risk of doing business. Sixth, complexity got the better of us. The industry let the growth in new instruments outstrip(超过)the operational capacity to manage them. As a result, operational risk increased dramatically and tiffs had a direct effect on the overall stability of the financial system. Last, and perhaps most important, financial institutions did not account for asset values accurately enough. I have heard some argue that fair value accounting -- which assigns current values to financial assets and liabilities -- is one of the main factors exacerbating(使恶化) the credit crisis. I see it differently. If more institutions had properly valued their positions and commitments at the outset, they would have been in a much better position to reduce their exposures.({B)}Fair value: a discipline for financial institutions({/B)} The daily marking of positions to current market prices was a key contributor to our decision to reduce risk relatively early in markets and in instruments that were deteriorating. This process can be difficult, and sometimes painful, but I believe it is a discipline that should define financial institutions. As a result of these lessons and others that will emerge from this financial crisis, we should consider important principles for our industry, for policymakers and for regulators. For the industry, we cannot let our ability to innovate exceed our capacity to manage. Given the size and interconnected nature of markets, the growth in volumes, the global nature of trades and their cross-asset characteristics, managing operational risk will only become more important. Risk and control functions need to be completely independent from the business units. And clarity as to whom risk and control managers report to is crucial to maintaining that independence. Equally important, risk managers need to have at least equal stature with their counterparts on the trading desks: if there is a question about the value of a position or a disagreement about a risk limit, the risk manager’s view should always prevail. Understandably, compensation continues to generate a lot of anger and controversy. We recognize that having troubled asset relief programme money creates an important context for compensation. That is why, in part, our executive management team elected not to receive a bonus in 2008, even though the firm produced a profit. More generally, we should apply basic standards to how we compensate people in our industry. The percentage of the discretionary (任意的)bonus awarded in equity should increase significantly as an employee’s total compensation increases. An individual’s performance should be evaluated over time so as to avoid excessive risk-taking. To ensure this, all equity awards need to be subject to future delivery and/or deferred exercise. Senior executive officers should be required to retain most of the equity they receive at least until they retire, while equity delivery schedules should continue to apply after the individual has left the firm.({B)}Limitations of self regulation({/B)} For policymakers and regulators, it should be clear that self-regulation has its limits. We rationalized and justified the downward pricing of risk on the grounds that it was different. We did so because our self-interest in preserving and expanding our market share, as competitors, sometimes blinds us -- especially when exuberance is at its peak. At the very least, fixing a system-wide problem, elevating standards or driving the industry to a collective response requires effective central regulation and the convening power of regulators. Capital, credit and underwriting standards should be subject to more" dynamic regulation". Regulators should consider the regulatory inputs and outputs needed to ensure a regime that is nimble and strong enough to identify and appropriately constrain market excesses, particularly in a sustained period of economic growth. Just as the Federal Reserve adjusts interest rates up to curb economic frenzy, various benchmarks and ratios could be appropriately calibrated. To increase overall transparency and help ensure that book value really means book value, regulators should require that, all assets across financial institutions be similarly valued. Fair value accounting gives investors more clarity with respect to balance sheet risk. The level of global supervisory co-ordination and communication should reflect the global interconnectedness of markets. Regulators should implement more robust information sharing and harmonized disclosure, coupled with a more systemic, effective reporting regime for institutions and main market participants. Without this, regulators will lack essential tools to help them understand levels of systemic vulnerability in the banking sector and in financial markets more broadly. In this vein, all pools of capital that depend on the smooth functioning of the financial system and are large enough to be a burden on it in a crisis should be subject to some degree of regulation.When the Long-Term Capital Management was disintegrated, the products initiated to counterweigh risks were ______. A．various basket indices and credit default swapsB．hedge fund and forward rate agreementsC．credit-linked notesD．current swaps and rates swaps
