未知题型 听力原文： Purse snatching is an increasingly common crimE.There are estimated 50 to 100 purse snatchings each month in the New York City subways. One of the favored techniques is to stand between two subway cars and, as the train starts pulling out of the station, reach out and pull free a woman's pursE.Recently, a crime analysis officer for the New York Police Department found that purse stealing in Manhattan's top restaurants was up 5 percent over the previous year. Where a woman puts her purse on a vacant chair at a table or at her feet beside her chair, she is inviting a purse snatcher to take it. Purse snatchers often work in pairs. When a target in a restaurant is sighted, one of them will create some kind of disturbance to gain the victim's attention. While the woman is looking away from her table, the actual snatcher will lift the pursE.A popular technique is for the thief, man or woman, to carry an umbrella with the curved handle down. The umbrella handle suddenly hooks the bag and in an instant it is on the thief's wrist or under the coat over his arm if he is a man, and on its way out of the restaurant. Police advise that women in restaurants keep their purses either on their laps or on the floor between their legs.Other purse snatchers who operate in theaters are called 'seat tippers', vietimizing women who put their purses down on an adjacent empty seat. Yet others specialize in snatching purses from ladies' rooms. When a woman is in a toilet stall, her purse should never be placed on the floor or hung on the coat hook on the door.(33)A.Officials from the New York Police Department.B.Officials from the New York federal government.C.Officials from the New York local government.D.Americans working in subway and restaurants.

未知题型 当烹调的食物中含有盐时，微波炉杀死常见食物中经常发现的有害细菌的功效就会消失。当在微波炉中加热时，不含食盐的食物内部达到了很高的足以把引起食物中毒的细菌杀死的温度，但是含有食盐的食物内部就达不到这样高的温度。于是科学家们就得出这样的结论，食盐可以有效地阻止微波加热食物的内部。 下面哪一个结论最能被上面的论述支持?D.如果不向将要在微波炉内加热的食物中加盐，食物中毒的危险性就会降低。
