问题     In families with two working parents, fathers may have more impact【C1】______a child’s language development than mothers, a new study【C2】______
    Researchers【C3】______92 families from 11 child care centers before their children were a year old, interviewing each to establish income,【C4】______of education and child care arrangements.【C5】______, it was a group of well-educated middle-class families,【C6】______married parents both living in the home.
    When the children were 2, researchers videotaped them at home in free-play sessions with both parents, recording all of their【C7】______The study will appear in the November【C8】______of The Journal of Applied Developmental Psychology.
    The scientists【C9】______the total number of utterances of the parents, the number of different words they used, the【C10】______of their sentences and other aspects of their speech.【C11】______average, fathers spoke less than mothers did, but they did not【C12】______in the length of utterances or proportion of questions asked.
    Finally, the researchers【C13】______the children’s speech at age 3, using a standardized language test. The only predictors of high【C14】______on the test were the mother’s level of education, the【C15】______of child care and the number of different words the father used.
    The researchers are【C16】______why the father’s speech, and not the mother’s, had an effect.
    "It’s well【C17】______that the mother’s language does have an impact," said Nadya Pancso far, the lead author of the study. "It【C18】______be that the high-functioning mothers in the study had already had a strong influence【C19】______their children’s speech development, or it may be that mothers are【C20】______in a way we didn’t measure in the study."
【C20】
选项 A、contributing
B、cultivating
C、instructing
D、enlightening
答案A
解析 动词辨析题。根据上文，研究人员感到不解的是为什么父亲的语言比母亲对孩子的影响更大。他们提出了两个可能的原因，其中第二个原因就是母亲语言影响孩子语言发展的方式他们尚未记录，因此用contribute(做出贡献)一词表示对孩子语言发展的总体上的帮助。而cultivate(培育)，instruct(教授)和enlighten(启蒙)在意义上不恰当。
