But many patients now live longer【C1】______of improvements in discovery and treatment. Researchers say death【C2】______in the United States from all cancers combined have fallen for thirty years. Survival rates have increased for most of the top fifteen cancers in both men and women, and for cancers in【C3】______. The National Cancer Institute and the Centers for Disease Control and Prevention studied the number of cancer survivors. A cancer survivor is defined【C4】______anyone who has been found to have cancer. This would include current patients. The study covered the period from 1971 to 2001. The researchers found there are three【C5】______as many cancer survivors today as there were thirty years ago. In 1971, the United States had about threemillion cancer survivors. Today there are about tenmillion. The study also found that 64% of adults with cancer can expect to still be【C6】______in five years. Thirty years ago, the five-year survival rate was 50%. The government wants to【C7】______the five-year survival rate to 70% by 2010. The risk of cancer increases with age. The report says the majority of survivors are 65 years and older. But it says medical improvements have also helped children with cancer live【C8】______longer. Researchers say 80% of children with cancer will survive at least five years after the discovery. About 75% will survive at【C9】______ten years. In the 1970s, the five-year survival rate for children was about 50%. In the 1960s, most children did not survive cancer. Researchers say they expect more improvements in cancer treatment in the future. In fact, they say traditional cancer-prevention programs are not enough anymore. They say public health programs should also aim to support the【C10】______numbers of cancer survivors and their families.

单选题 Stiletto heels could be banned from the workplace because of health and safety reasons, according to British Trade Union bosses. The Trade Union Congress, predominantly male, has proposed a motion arguing that high heels are disrespectful to women while they also contribute to long term injuries. They propose instead that women wear 'sensible shoes' with an inch heel limit in an attempt to avoid future foot and back pain as well as injuries. The motion is due to be debated at next month's conference. The motion states: 'Congress believes high heels may look glamorous on the Hollywood catwalks but are completely inappropriate for the day-to-day working environment.' 'Feet bear the main burden of daily life, and for many workers long-time standing, badly fitted footwear, and in particular high heels can be a hazard. Around two million days a year are lost through sickness as a result of lower limb disorders.' 'Wearing high heels can cause long-term foot problems and also serious foot, knee and back pain and damaged joints.' 'Many employers in the retail sector force women workers to wear high heels as part of their dress code. ' 'More must be done to raise awareness of this problem so that women workers and their feet are protected.' Nadine Dorries, the Tory Member of Parliament, however criticised the motion and said the extra height heels give women can help them when in the workplace. 'I'm 5 ft 3 in and need every inch of my Christian Louboutin heels to look my male colleagues in the eye,' she said. 'If high heels were banned in Westminster, no one would be able to find me. The Trade Union leaders need to get real, stop using obvious sexist methods by discussing women's very high thin heels to divert (转移) tension away from Labour chaos.' Michelle Dewberry, a former winner of The Apprentice, said the motion was patronising (自认为高人一 等的). 'This is absolutely ridiculous and I think these union officials should be spending their time dealing with more important issues', she said. 'I'm at work in five-inch heels and perfectly able to do my job. Heels are sexy, they boost your confidence and make women feel that they are in control of their life. I can't imagine these officials debating a motion about how tightly men should wear their ties. Wearing heels is a personal choice.'

单选题 Plastic Surgery A better credit card is the solution to ever larger hack attacks A. A thin magnetic stripe(magstripe)is all that stands between your credit-card information and the bad guys. And they've been working hard to break in. That's why 2014 is shaping up as a major showdown: banks, law enforcement and technology companies are all trying to stop a network of hackers who are succeeding in stealing account numbers, names, email addresses and other crucial data used in identity theft. More than 100 million accounts at Target, Neiman Marcus and Michaels stores were affected in some way during the most recent attacks, starting last November. B. Swipe(刷卡)is the operative word: cards are increasingly vulnerable to attacks when you make purchases in a store. In several recent incidents, hackers have been able to obtain massive information of credit-, debit-(借记)or prepaid-card numbers using malware, i.e. malicious soft-ware, inserted secretly into the retailers' point-of-sale system—the checkout registers. Hackers then sold the data to a second group of criminals operating in shadowy corners of the web. Not long after, the stolen data was showing up on fake cards and being used for online purchases. C. The solution could cost as little as $2 extra for every piece of plastic issued. The fix is a security technology used heavily outside the U. S. While American credit cards use the 40-year-old magstripe technology to process transactions, much of the rest of the world uses smarter cards with a technology called EMV(short for Europay, MasterCard, Visa)that employs a chip embedded in the card plus a customer PIN( personal identification number)to authenticate(验证)every transaction on the spot. If a purchaser fails to punch in the correct PIN at the checkout, the transaction gets rejected. (Online purchases can be made by setting up a separate transaction code.) D. Why haven't big banks adopted the more secure technology? When it comes to mailing out new credit cards, it's all about relative costs, says David Robertson, who runs the Nilson Report, an industry newsletter. 'The cost of the card, putting the sticker on it, coding the account number and expiration date, embossing(凸印)it, the small envelope—all put together, you're in the dollar range.' A chip-and-PIN card currently costs closer to $3, says Robertson, because of the price of chips. (Once large issuers convert together, the chip costs should drop.) E. Multiply $3 by the more than 5 billion magstripe credit and prepaid cards in circulation in the U. S. Then consider that there's an estimated $12.4 billion in card fraud on a global basis, says Robertson. With 44% of that in the U. S. American credit-card fraud amounts to about $5.5 billion annually. Card issuers have so far calculated that absorbing the liability for even big hacks like the Target one is still cheaper than replacing all that plastic. F. That leaves American retailers pretty much alone the world over in relying on magstripe technology to charge purchases—and leaves consumers vulnerable. Each magstripe has three tracks of information, explains payments security expert Jeremy Gumbley, the chief technology officer of CreditCall, an electronic-payments company. The first and third are used by the bank or card issuer. Your vital account information lives on the second track, which hackers try to capture. 'Malware is scanning through the memory in real time and looking for data,' he says. 'It creates a text file that gets stolen.' G. Chip-and-PIN cards, by contrast, make fake cards or skimming impossible because the information that gets scanned is encrypted (加密). The historical reason the U. S. has stuck with magstripe, ironically enough, is once superior technology. Our cheap, ultra-reliable wired net-works made credit-card authentication over the phone frictionless. In France, card companies created EMV in part because the telephone monopoly was so maddeningly inefficient and expensive. The EMV solution allowed transactions to be verified locally and securely. H. Some big banks, like Wells Fargo, are now offering to convert your magstripe card to a chip-and-PIN model. (It's actually a hybrid(混合体)that will still have a magstripe, since most U. S. merchants don't have EMV terminals.) Should you take them up on it? If you travel internationally, the answer is yes. I. Keep in mind, too, that credit cards typically have better liability protection than debit cards. If someone uses your credit card fraudulently(欺炸性地), it's the issuer or merchant, not you, that takes the hit. Debit cards have different liability limits depending on the bank and the events surrounding any fraud. 'If it's available, the logical thing is to get a chip-and-PIN card from your bank,' says Eric Adamowsky, a co-founder of CreditCardInsider. com. 'I would use credit cards over debit cards because of liability issues. 'Cash still works pretty well too. J. Retailers and banks stand to benefit from the lower fraud levels of chip-and-PIN cards but have been reluctant for years to invest in the new infrastructure(基础设施)needed for the technology, especially if consumers don't have access to it. It's a chicken-and-egg problem: no one wants to spend the money on upgraded point-of-sale systems that can read the chip cards if shoppers aren't car-tying them—yet there's little point in consumers' carrying the fancy plastic if stores aren't equipped to use them. (An earlier effort by Target to move to chip and PIN never gained progress.) According to Gumbley, there's a 'you-first mentality. The logjam(僵局)has to be broken.' K. JPMorgan Chase CEO Jamie Dimon recently expressed his willingness to do so, noting that banks and merchants have spent the past decade suing each other over interchange fees—the percentage of the transaction price they keep—rather than deal with the growing hacking problem. Chase offers a chip-enabled card under its own brand and several others for travel-related companies such as British Airways and Ritz-Carlton. L. The Target and Neiman hacks have also changed the cost calculation: although retailers have been reluctant to spend the $6.75 billion that Capgemini consultants estimate it will take to convert all their registers to be chip-and-PIN compatible, the potential liability they now face is dramatically greater. Target has been hit with class actions from hacked consumers. 'It's the ultimate nightmare,' a retail executive from a well-known chain admitted to TIME. M. The card-payment companies MasterCard and Visa are pushing hard for change. The two firms have warned all parties in the transaction chain—merchant, network, bank—that if they don't become EMV-compliant by October 2015, the party that is least compliant will bear the fraud risk. N. In the meantime, app-equipped smartphones and digital wallets—all of which can use EMV technology—are beginning to make inroads(侵袭)on cards and cash. PayPal, for instance, is testing an app that lets you use your mobile phone to pay on the fly at local merchants—without surrendering any card information to them. And further down the road is biometric authentication, which could be encrypted with, say, a fingerprint. O. Credit and debit cards, though, are going to be with us for the foreseeable future, and so are hackers, if we stick with magstripe technology. 'It seems crazy to me,' says Gumbley, who is English, 'that a cutting-edge-technology country is depending on a 40-year-old technology.' That's why it may be up to consumers to move the needle on chip and PIN. Robertson says 'When you get the consumer into a position of worry and inconvenience, that's where the rubber hits the road.'
