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] 【C7】
选项
答案 H
解析 空格前面是助动词does not，后面是动词indicate，故应填入副词修饰动词。本句句意为，人体内有这些化学物质不一定就有健康风险，而not已表示否定含义，因此应填入含“一定”意思的副词，由此推断答案是necessarily。在备选的副词中，habitually意为“习惯性地”，与句意不符，故排除。
