问题     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、possible
B、prone
C、resistant
D、averse
答案 B
解析 形容词辨析题。根据空格前的连词and可知，此处that引导的宾语从句与上文中的that从句是并列关系，因此可推测两个从句表达的意义相近，且该形容词应该能与to构成搭配。分析选项可以看出，prone“很可能……的，有……倾向的”符合句意。possible“可能的”，resistant“抵抗的”，averse“厌恶的；反对的”，用在此处均不合适。
