问题     Today’s kindergarteners are heavier than kids brought up in
the 1970s and 1980s and appear to be on the road to become【M1】______
overweight and obese in the years to come, a new study finds.
    "It’s not just kids are already overweight getting more and more【M2】______
so, there is an entire shift. Even those who are abnormal weight【M3】______
are gaining weight," said lead study author Ashlesha Datar,
serious economist at RAND Corp. in Santa Monica, Calif.【M4】______
    Researchers analyzed data on to nearly 6,000 white, black and【M5】______
Hispanic children who participated in the Early Childhood
Longitudinal Study—a nationally representative example—and【M6】______
had their height and weight measure over nine years, in【M7】______
kindergarten, first, third, fifth and eighth grades.
    The study found nearly 40 percent of kindergarteners had a
body mass index(BMT)in the 75th percentile or above, down【M8】______
from 25 percent in the 1970s and 1980s, when the growth charts
are developed by the U.S. Centers for Disease Control and【M9】______
Prevention. While a BMI in the 75th percentile is still in the
normal range, that child may be headed for being overweight or
obese, Datar said. And if they’re already at the 75th percentile in
kindergarten, they don’t have far to go before they tip the【M10】______
overweight or obese category, which puts them at risk of serious
health problems as adults.

解析 词汇错误。example表示“例子”,而此处是指6000多个孩子作为统计“样本”,应该是sample。
