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] 【C5】
选项
答案
K
解析
该空格位于主语the Environmental Protection Agency之后,宾语the type andamount之前,本句中又含有明确的时间状语in 2001,故应填入动词的过去式,综合上下文考虑,本句含义应为“环保部门限制了铅使用的种类和数量”。故答案为K)restricted“限制,限定”。备选项中overwhelmed与上下文语义不符,故排除,而其他选项的词形均不符合要求。
