Questions 47 to 56 are based on the followingpassage.
In families with two working parents, fathersmay have more impact on a child’s languagedevelopment than mothers, a new study suggests.
Researchers 47 92 families form 11 child carecenters before their children were a year old, interviewing each to establish income, level ofeducation and child care arrangements. Overall, it was a group of well-class families, withmarried parents both living in the home.
When the children were 2, researchers videotaped them at home in free-play sessions withboth parents, 48 all of their speech. The study will appear in the November issue of TheJournal of Applied Developmental Psychology.
The scientists measured the 49 number of utterance (话语) of the parents, the number ofdifferent words they used, the complexity of their sentences and other 50 of their speech. Onaverage, fathers spoke less than mothers did, but they did not differ in the length ofutterances or proportion of questions asked.
Finally, the researchers 51 the children’s speech at age 3, using a standardized languagetest. The only predictors of high scores on the test were the mother’s level of education, the 52 of child care and the number of different words the father used.
The researchers are 53 why the father’s speech, and not the mother’s, had an effect.
“It’s well 54 that the mother’s language does have an impact,” said Nadya Pancsofar, thelead author of the study. It could be that the high-functioning mothers in the study had 55 hada strong influence on their children’s speech development, Ms. Pancsofar said, “or it may bethat mothers are 56 in a way we didn’t measure in the study.”
