The casino(赌场)at the smart Atlantis resort on Paradise Island in the Bahamas is bigger than 20 tennis courts. Tourists flit from slot machine to roulette table, drift past Temples of the Sun and Moon and walk by Crystal Gate and Poseidon"s Throne. But the only Bahamians in sight are waiters, croupier and cashiers. The Bahamas legalised casino gambling in 1969, when they were still a British colony. But mainly because of the influence of local pastors, both Bahamians and foreigners who live in the country are banned from gambling. This has not stopped residents from placing bets. Instead, they gamble off the books in " number houses" or "webshops"—legal internet cafes that offer illegal bets on the side and operate in plain sight. These have mushroomed in recent years, even as tourism has stagnated and hotels have reduced staff. This pretence will be put to the test on January 28 th, when a referendum will be held on legalising gambling in web shops, as well as on a separate proposal to set up a national lottery. The well-funded campaign supporting the initiative has been distributing posters and T-shirts. It argues that web shops account for almost 2% of jobs in the country, and that gambling taxes could help close the budget deficit. The "no" movement, which calls itself "Save Our Bahamas" , is led by the islands" evangelical(新教会的)churches. Perry Christie, the prime minister, says he has "no horse in the race". The opposition accuses him, without proof, of running a "fixed" referendum on behalf of web-shop owners who back him financially. If the proposal is approved, the government will probably try to pass a series of reforms supported by the big hotel casinos. In order to compete with Las Vegas, New Jersey or Macau, they say, they need authorisation for credit-card payment for chips, online and mobile wagers, private VIP gaming rooms and betting on sports matches while play is in progress. They also want stronger legal tools to collect unpaid debts and the right to void payments caused by computer errors. The tourism minister has already announced support for these policies. However, letting Bahamians into the casinos is not yet on the agenda. Perry Christie was charged because of______.

A. public bribe
B. unfair voting
C. budget deficit
D. horse-race gamble

A young consultant"s life is tiring. A typical week starts before dawn on Monday, with a rush to the airport and a flight to wherever the client is based. A typical brain-for-hire can expect to stay in hotels at least three nights a week, texting a distant lover. " It"s quite normal to spend a year living out of a suitcase," sighs one London-based consultant. An ex-McKinseyite in New York adds that 15 to 18-hour weekdays are normal and six to eight-hour Saturdays and Sundays common. It can be draining, she admits. So the job appeals to "insecure over-achievers"—a phrase widely used in the industry—"who are always worried that they haven"t done enough work," jokes a former employee of Bain & Company. Some 60—65% of consultants are recent college-leavers. Most drop out within a few years and take more settled jobs elsewhere in the business world, where their experience and contacts allow them to do better than their less-travelled counterparts. The elite consultancies have offices in big cities, which is where ambitious young people want to live. The best-paid jobs are in places like London, New York and Shanghai. Such cities are also where the culture and dating opportunities are richest. "Everything that happens, happens in London," says Una Paulauskaite of the Young Management Consultancies Association, speaking of Britain. Other countries are less unipolar, but all have a divide between the big city and the remote areas. Companies based outside the big cities also need " clever people doing clever stuff" , as one consultant puts it. "But" , he adds, citing a litany of dull suburban towns in which he has managed projects, " there is no way in hell I"d have taken a permanent job in one of those places. " A recent graduate working at a rival firm agrees: " I wouldn"t have considered working for a firm outside London. " Such attitudes are frustrating for firms in Portsmouth or Peoria. But consultancies benefit from remote areas. They recruit bright young things in the metropolis and then hire out their brains to firms in the sticks. This is one reason why consultants have to travel so much. The system works, more or less, for everyone. Firms in the provinces get to borrow talent they could not easily hire. And young consultants get to experience life in the real world before returning to the capital to party with their friends at the weekend. They have it all; except enough sleep. The last two paragraphs tell us that______.

A. the present system is to some degree favorable to both firms and consultants
B. consultancies outside big cities need clever people
C. consultants like travelling because they want to become successful
D. consultancies prefer to run their business in remote areas

In 1977, the year before I was born, a Senate committee led by George McGovem published its landmark " Dietary Goals for the United States," urging Americans to eat less high-fat red meat, eggs and dairy and replace them with more calories from fruits, vegetables and especially carbohydrates. By 1980 that wisdom was codified. The US Department of Agriculture(USDA)issued its first dietary guidelines, and one of the primary directives was to avoid cholesterol(胆固醇)and fat of all sorts. The National Institutes of Health(NIH)recommended that all Americans over the age of 2 cut fat consumption, and that same year the government announced the results of a $ 150 million study, which had a clear message; Eat less fat and cholesterol to reduce your risk of a heart attack. The food industry—and American eating habits—jumped in step. Grocery shelves filled with "light" yogurts, low-fat microwave dinners, cheese-flavored crackers, cookies. Families like mine followed the advice; beef disappeared from the dinner plate, eggs were replaced at breakfast with cereal or yolk-free beaters, and whole milk almost wholly vanished. From 1977 to 2012, per capita consumption of those foods dropped while calories from supposedly healthy carbohydrates increased—no surprise, given that breads, cereals and pasta were at the base of the USDA food pyramid. The nation was embarking on a " vast nutritional experiment," as the skeptical president of the National Academy of Sciences, Philip Handler, put it in 1980. But with nearly a million Americans a year dropping dead from heart disease by the mid-"80s, it had to try something. Nearly four decades later, the results are in: the experiment was a failure. Americans cut the fat, but by almost every measure, they are sicker than ever. The prevalence of Type 2 diabetes in the US increased 166% from 1980 to 2012. Nearly 1 in 10 American adults has the disease, costing the country"s health care system $ 245 billion a year, and an estimated 86 million people are predia-betic. Deaths from heart disease have fallen—a fact that many experts attribute to better emergency care, less smoking and widespread use of cholesterol-controlling drugs like statins—but cardiovascular(心血管的)disease remains the country"s No. 1 killer. What can be inferred from the last paragraph

A. Dietary change has contributed little to America.
B. About ten percent of Americans are prediabetic.
C. The change of diet has killed many diseases.
D. America"s obesity rate is higher than before.
