Doctors and researchers have begun to look for causes of overweight in a critical period of life—the nine months before birth. Research has found that women who gain too much weight in pregnancy【C1】______to have heavier babies, and that heavier babies are【C2】______more to obesity later on.
However, for some time, researchers have not been able to【C3】______out the role of genes. A new study helps eliminate that【C4】______By looking at a large group of women who gave birth at least twice between 1989 and 2003, researchers were able to【C5】______different pregnancies in the same women. Based on the data, the authors【C6】______that maternal weight gain during pregnancy【C7】______to higher infant birth weights,【C8】______of genetic factors.
The authors of the study【C9】______birth records of 513 501 women and their 1164 750【C10】______born over a 15-year period in New Jersey. However, researchers【C11】______mothers with gestational diabetes (妊娠糖尿 病) and babies born before 37 or after 41 weeks.
【C12】______they found was that mothers who gained more than 53 pounds during pregnancy were more than twice as【C13】______to have a high-birth-weight baby as women who put【C14】______18 to 22 pounds. David Ludwig of Children’s Hospital Boston says "An【C15】______time to begin obesity prevention efforts for the next generation actually begins【C16】______birth."
Traditionally the public-health focus has been【C17】______making sure that women gain enough weight during pregnancy, to【C18】______their risk of having babies with low birth weights. Now, however, 【C19】______more than half of the US population being either overweight or obese, the focus has largely【C20】______to the other end of the spectrum, to women who gain too much weight.

选项
A、distinguish
B、compare
C、test
D、distinct
答案
B
解析
动词辨析题。解答本题应联系上文。上文提到研究者选取至少生过两个孩子的母亲作为实验对象。根据实验目的可推测,他们需要对比在不同怀孕期间的增重情况与婴儿体重的关系,所以此空格处填入的动词应含有“对比,比较”的含义,故compare为正确答案。
