问题     As an Alaskan fisherman, Timothy June, 54, used to think that he was safe from industrial pollutants(污染物)at his home in Haines—a town with a population of 2,400 people and 4,000 eagles, with 8 million acres of protected wild land nearby. But in early 2007, June agreed to take part in a【C1】______of 35 Americans from seven states. It was a biomonitoring project, in which people’s blood and urine (尿)were tested for【C2】______of chemicals—in this base, three potentially dangerous classes of compounds found in common household【C3】______like face cream, tin cans, and shower curtains. The results-【C4】______ in November in a report called "Is It in Us?" by an environmental group-were rather worrying. Every one of the participants,【C5】______from an Illinois state senator to a Massachusetts minister, tested positive for all three classes of pollutants. And while the【C6】______presence of these chemicals does not【C7】______indicate a health risk, the fact that typical Americans carry these chemicals at all【C8】______June and his fellow participants.
    Clearly, there are chemicals in our bodies that don’t【C9】______there. A large, ongoing study conducted by the Centers for Disease Control and Prevention has found 148 chemicals in Americans of all ages. And in 2005, the Environmental Working Group found an【C10】______of 200 chemicals in the blood of 10 new-borns. "Our babies are being born pre-polluted," says Sharyle Patton of Commonweal, which cosponsored "Is It in US?" "This is going to be the next big environmental issue after climate change. "
A)analyses I)products
B)average J)ranging
C)belong K)released
D)demonstrated L)shocked
E)excess M)simple
F)extending N)survey
G)habitually O)traces
H)necessarily [br] 【C2】
选项
答案 O
解析 空格前面是介词for，后面是介词of，因此本空应填入名词，与of chemicals一词作介词for的宾语。根据句意可知，该项目的目的是检测人们的血液和尿液中是否存在化学物质，故空格处应填入含有“迹象、痕迹”意思的词，因此答案为Otraces。在备选的名词中，survey在上一题题已使用，可排除；analyses of chemicals与该句中的tested重复；average，excess和products均不符合文意，可排除。
