2.We haven't found the solution __________ the problem yet.

Scientists in the 1950s proclaimed the robot the brainwave (灵感，灵机) of the future—it would free housewives of drudgery (单调沉闷的工作) and fill factories with tireless work force. But in many ways, the brainwave has been a washout. Robots can paint cars, salvage (收集) nuclear fuel and even assist in brain surgery, but theyre still pretty dumb. Mr. Reddy says robots are dumb "because we havent taken the trouble to put the pieces together, not because we dont know how. That takes money and time and effort, and we dont have the money". But today robots can recognize forms and shapes and measure distances. They can hear and speak by using computers that recognize thousands of words. Their sensors can detect smoke or fumes. They can move about rolling on wheels or walk with as many as eight legs like a spider on uneven terrain (地面,地带). In addition, they can recognize texture and the force of a movement, such as pressing. Many robots have one or two of these abilities to some degree, but creating a competent robot that combines most or all of them has been difficult. Scientists have also found it difficult to match human abilities that most people take for granted such as the fingers dexterity (灵巧,熟练) or the ability to identify objects. "The list of things that robots can do better than humans is much shorter than the list of things robots cannot," says Tom Smith from the Cambridge Mellon Institute.

to adulthood who are saddled with uttbearable levels of debt, the conversation is almost always about student loan debt. But theres a growing body of evidence suggesting that todays young adults are also drowning in credit-card debt-and that many of them will take this debt to their graves. More than 20% overspent their income by more than $100 every single month. Since they havent built up their credit histories yet, its a safe bet that theae young adults are paying relatively high interest rates on the resulting credit card debt. Although many young people blame "Socializing" a~ a barrier to saving money, most of them arent knocking back $ 20 drinks in trendy (时尚的) lounges. Theyre struggling with much more daily financial demands. To a disturbingly large extent, the young and the broke are relying on credit cards to make it until their next payday. This obviously isnt sustainable in the long run, and its going -to put a huge drag on, their spending power even after they reach their peak earning years, becattse theyll sttll be paying interest on that bottle Of orange juice or box of spaghetti (意式面条) they bOUght a decade earlier. A new study out of Ohio State University found that young adults are accumulating credit card debt at a more rapid rate than other age groups, and that theyre slower at paying it off, "If what we found continues to hold true, we may have more elderly people with substantial financial problems in the future," warns Lucia Duma, professor of economics at Ohio State, "If our persist, we may be faced with a financial crisis among elderly ,people who cant pay off their credit cards, " Dunn says a lot of these young people are never going to get out from under their credit card debt."Many people are borrowing on credit cards so heavily that payoff rates at these levels are not sufficient to recover their credit card debt by the end of their life, which could have loss implications for the credit card issuing banks.
