问题     According to a report from the Harvard School of Public Health, many everyday products, including some bug sprays and cleaning fluids, could lead to an increased risk of brain and behavioral disorders in children. The developing brain, the report says, is particularly【C1】______to the toxic effects of certain chemicals these products may contain, and the damage they cause can be【C2】______.
    The official policy, however, is still evolving. Health and environmental【C3】______have long urged U. S. government agencies to【C4】______the use of some of the 11 chemicals the report cites and called for more studies on their long-term effects. In 2001, for example, the Environmental Protection Agency【C5】______the type and amount of lead that could be present in paint and soil in homes and child-care【C6】______, after concerns were raised about lead poisoning. The agency is now【C7】______the toxic effects of some of the chemicals in the latest report.
    But the threshold for regulation is high. Because children’s brain and behavioral disorders, like hyperactivity and lower grades, can also be linked to social and genetic factors, it’s tough to pin them on exposure to specific chemicals with solid【C8】______evidence, which is what the EPA requires. Even the Harvard study did not prove a direct【C9】______but noted strong associations between exposure and risk of behavioral issues.
    Nonetheless, it’s smart to【C10】______caution. While it may be impossible to prevent kids from drinking tap water that may contain trace amounts of chemicals, keeping kids away from lawns recently sprayed with chemicals and freshly dry-cleaned clothes can’t hurt. A)advocates I)particles
B)compact J)permanent
C)correlation K)restricted
D)exercise L)simulating
E)faculties M)statistical
F)interaction N)tighten
G)investigating O)vulnerable
H)overwhelmed [br] 【C3】
选项
答案 A
解析 该空格位于形容词environmental之后，且其后紧接的就是谓语动词have longurged…，由此判断此处应填入复数形式的名词，作句子的主语。本句主语所发出的动作是“敦促政府部门做某事”，因此应填入advocates。故答案为A)advocates“拥护者，提倡者”。备选项中correlation及interaction均是单数形式，而facilities与particles与上下文语义不符，故均排除。
