[单项选择]Watching a three-and-a-half-pound chicken roast in 14 minutes, time loses all meaning. The skin turns gold and crisp, juices immediately rise to the surface, and the flesh firms before your eyes. It’s dizzying and seductive, like the home makeovers on TV that compress as "Wow." you think "I could do this every single night."
The makers of the TurboChef, a super-fast oven, used at Subway and Starbucks and, recently, by chefs like Charlie Trotter and Gray Kurtz, are banking on that reaction. Speed ovens made by TurboChef, Merrychef. Electrolux and others are common in commercial kitchens: they generally use some layering of microwave, convection, steam and infrared technologies, which provides even cooking, moistness and browning, all at high speed. No single technology has been able m produce all of those traits.
The combination ovens are also mining up. in more limited roles, in some fine-dining kitchens. Mr. Trotter installed a commercial TurboChef in his upscale takeout caf

[单项选择]A hundred years ago it was assumed and scientifically "proved" by economists that the laws of society make it necessary to have a vast army of poor and jobless people in order to keep the economy going. today, hardly anybody would dare to voice the principle. It is generally accepted that nobody should be excluded from the wealth of the nation, either by the law of nature or by those of society. The opinions are outdated, which were current a hundred years ago, that the poor owed their conditions to their ignorance, lack of responsibility. In all western industrialized countries, a system of insurance has been introduced which guarantees everyone a minimum of subsistence in case of unemployment, sickness and old age.
