问题     After visiting Widener University and learning about its program requiring 300 hours of community service in the surrounding poor city of Chester, Pennsylvania, Anna Miller told her father that she would not go anywhere else. Miller was looking for a college experience that was【C1】________on both meaning and action.
    "I was especially【C2】________to this program because it is much easier to make a lasting change in a community when you have the【C3】________of the administration of the school," said the 20-year-old from East Prospect, Pennsylvania. Widener is not【C4】________in its creative curriculum: a number of schools now include community service as part of class work.
    During the 1960s and 1970s, universities were often the【C5】________of student protests, characterized as ivory-tower institutions【C6】________the greater problems in society.【C7】________these days, many universities are【C8】________the forefront of encouraging students to【C9】________social change. "It’s very【C10】________. at all different kinds of colleges, from small liberal-arts colleges to big universities and community colleges," says Debra Humphreys, a spokesperson for the Association of American Colleges and Universities. According to a 2009【C11】________by the AACU, at least 68 percent of its members are including credit-bearing courses that【C12】________service learning.
    Colleges and universities are【C13】________community service with every type of subject. At the University of Pennsylvania, students can take an environmental-studies class where they identify sources of lead, gather samples of soil, dust, and paint, and map the risk of lead【C14】________in surrounding West Philadelphia areas. Last year【C15】________1,800 students elected to take at least one of the 60 "academically based community service" courses offered through the Netter Center for Community Partnerships.
    At Bryn Mawr College, math professor Victor Don-nay links math to projects【C16】________sustainability, like the savings from eliminating dining trays in dorm cafeterias. It’s【C17】________to see how math can be used to make a difference in the world, Donnay says. "As they did the projects, the【C18】________of effort they put in and their【C19】________for figuring out these problems was much higher than in a【C20】________class."
【C14】

选项 A、content
B、storage
C、deposit
D、exposure

答案D

解析 由于该词的定语为lead(铅),而且中心词为the risk(风险),因此答案为D项exposure“暴露,接触(有毒有害物质)”,意为“暴露在铅污染的危险中”。A项content“含量”,含铅量大的话,才会有风险,所以A不选。B项storage“存储”以及C项deposit“沉积”都属于中性词,不去接触都没有直接的危险,所以都予以排除。
