【正文】 e sports, 37% have volunteered and 41% have taken arts classes.[J]Especially in affluent families, children start young. Nearly half of highearning, collegegraduate parents enrolled their children in arts classes before they were 5, pared with of low ine, lesseducated parents. Nonetheless, 20% of welloff parents say their children’s schedules are too hectic, pared with 8% of poorer parents.[K]Another example is reading aloud, which studies have shown gives children bigger vocabularies and better reading prehension in school. 71% of parents with a college degree say they do it every day, pared with 33% of those with a high school diploma or less. White parents are more likely than other to read to their children daily, as are married parents. Most affluent parents enroll their children in preschool or day care, while lowine parents are more likely to depend on family members. Discipline techniques vary by education level: 8% of those with a postgraduate degree say they often beat their children, pared with 22% of those with a high school degree or less.[L]The survey also probed attitudes and anxieties. Interestingly, parents’ attitudes toward education do not seem to reflect their own educational background as much as a belief in the importance of education for upward mobility. Most American parents say they are not concerned about their children’s grades as long as they work hard. But 50% of poor parents say it is extremely important to them that their children earn a college degree, pared with 39% of wealthier parents. f[M]Lesseducated parents, and poorer and black and Latino parents are more likely to believe that there is no such thing as too much involvement in a child’s education. Parents who are white, wealthy or collegeeducated say too much involvement can be bad. Parental anxieties reflect their circumstances. Highearning parents are much more likely to say they live in a good neighborhood for raising children. While bullying is parents’ greatest concern over all, nearly half of lowine parents worry their child will get shot, pared with onefifth of highine parents. They are more worried about their children being depressed or anxious.[N]In the Pew survey, middleclass families earning between $30,000 and $75,000 a year fell right between workingclass and highearning parents on issues like the quality of their neighborhood for raising children, participation in extracurricular activities and involvement in their children’s education.[O]Children were not always raised so differently. The achievement gap between children from high and lowine families is 3040% larger among children born in 2001 than those born 25 years earlier, according to Mr. Reardon’s research. People used to live near people of different ine levels。 neighborhoods are now more segregated by ine. More than a quarter of children live in singleparent households — a historic high, according to Pew — and these children are three times as likely to live in poverty as those who live with married parents. Meanwhile, growing ine inequality has coincided with the increasing importance of a college degree for earning a middleclass wage.[P]Yet there are recent signs that the gap could be starting to shrink. In the past decade, even as ine inequality has grown, some of the socioeconomic differences in parenting, like reading to children and going to libraries, have narrowed.[Q] Public policies aimed at young children have helped, including public preschool programs and reading initiatives. Addressing differences in the earliest years, it seems, could reduce inequality in the next, generation.注意：此部分試題請(qǐng)?jiān)诖痤}卡2上作答。 parents teach their children to be obedient and show respect to adults. parents, whether rich or poor, have similar expectations of their children despite different ways of parenting. rich parents are more concerned with their children’s psychological wellbeing, poor parents are more worried about their children’s safety. increasing differences in child rearing between rich and poor families reflect growing social inequality. approaches of workingclass and affluent families both have advantages. families and workingclass families now tend to live in different neighborhoods. punishment is used much less by welleducated parents.. Lareau doesn’t believe participating in fewer afterclass activities will negatively affect children’s development. parents are concerned about their children’s mental health and busy schedules. socioeconomic differences in child rearing have shrunk in the past ten years.36.【解析】[D]。根據(jù)題干中的關(guān)鍵詞A number of factors 和 driving down the global oil prices 可定位至[D]段第三、四句。37.【解析】[L]。根據(jù)題干中的關(guān)鍵詞Pricing carbon 和 the most economical way 可定位至[L]段第 二句。38.【解析】[J]。根據(jù)題干中的關(guān)鍵詞African children可定位至[J]段第二句。39.【解析】[E]。根據(jù)題干中的關(guān)鍵詞 oversupply and decreasing demand 可定位至[E]段最后一句。40.【解析】[H]。根據(jù)題干中的關(guān)鍵詞higher fossil fuel prices 以及 innovation and application of cleaner technology可定位至[H]段第二句。41.【解析】[A]。根據(jù)題干中的關(guān)鍵詞remain low for a long time 和 higher emissions of greenhouse gases可定位至[A]段第一、三句。42.【解析】[G]。根據(jù)題干中的關(guān)鍵詞primary energy consumption可定位至[G]段第二句。43.【解析】[F]。根據(jù)題干中的關(guān)鍵詞major fossil exporting countries 和 develop renewable energies可定位至[F]段第二句。44.【解析】[O]。根據(jù)題干中的關(guān)鍵詞not properly dealt with 和 pose endless risks 可定位至[O] 段最后一句。45.【解析】 [B]。細(xì)節(jié)題。根據(jù)題干中的關(guān)鍵詞urgent for governments, increase the cost 和 lessen the catastrophic effects可定位至[B]段第二句。Section CDirections: There are 2 passages in this section.
