Congested cities are fast becoming test tubes for scientists
studying the impact of traffic fumes on the brain. As roadways
choke on traffic, researchers suspect that the tailpipe exhausted【M1】______
from cars and trucks—especially tiny carbon particles already
implicated heart disease, cancer and respiratory ailments—may【M2】______
also injure brain cells the key to learning and memory. New【M3】______
public-health studies and laboratory experiments suggest that, at
every stage of life, traffic fumes exact a measuring toll on mental【M4】______
capacity, intelligence and emotional stability.
Children in areas affected by high levels of emissions, on
average, scored more poor on intelligence tests and were more【M5】______
prone to depression, anxiety and attention problems than children
growing in cleaner air, separate research teams in New York,【M6】______
Boston, Beijing, and Krakow, Poland, found. And older men and
women long exposing to higher levels of traffic-related particles【M7】______
and ozone had memory and reasoning problems effectively added【M8】______
five years to her mental age, other university researchers in Boston【M9】______
reported this year. The emissions may also height the risk of【M10】______
Alzheimer’s disease and speed the effects of Parkinson’s disease.
"The evidence is growing that air pollution can affect the
brain," says medical epidemiologist Heather Volk at USC’s Keck
School of Medicine. "We may be starting to realize the effects are
broader than we realized." [br] 【M8】
选项
答案
added∧一that/which或added一adding
解析
语法错误。本句是定语从句,先行词memory and reasoning problems在定语从句中充当主语,故关系代词不能省略,应加上that或which。另外也可以把added改成adding,作后置定语修饰problems。
