14．Music lessons in early childhood bring about changes in the brain that  could improve its performance far into adulthood，researchers say．
  Brain scans of young adults showed those who had formal musical training before seven had thicker brain areas dealing with hearing and self-awareness．
  The findings note how brain development can be influenced by the age when children start to learn a musical instrument，and how those changes can continue into later life．
"Early musical training benefits kids more than just making them enjoy music．It changes the brain，which could bring about cognitive advances as well，"said Yunxin Wang of Beijing Normal University．
"Our results suggest it's better to start musical training before seven，which agrees with what most piano teachers recommend，"she added．She hoped the results might help parents decide when was the best for their children to learn an instrument．
   The brain's cortex（皮层） plays a leading role in one's abilities，from thought and language to memory and attention．The area matures rapidly in the early years of life，and its development could be affected more if a person starts musical training before it fully matures．
   Wang studied 48 Chinese students aged between 19 and 21 who had received formal music training for at least a year sometime between the ages of 3 and 15．Each had a scan to measure the thickness of the brain's cortex．
   After considering sex and the number of years spent having music lessons，Wang found that musical training that started before seven appeared to thicken areas of the brain involved in language skills and executive function，which is a person's ability to plan and accomplish tasks．
"We're not sure why these changes occur，but a reasonable explanation is that early starters might depend more on hearing clues（线索） when learning music，since it might be more difficult for younger children to read music，"Wang said．
32．According to the researchers，musical training before the age of seven canA
A．contribute to future work．
B．create a successful life
C．develop all-round abilities
D．deal with puzzling problem

A．it must be hard for kids to read music
B．kids are more likely to learn music by hearing
C．Wang's explanation has been the most reasonable
D．Wang will research into the reasons for the brain change
35．For what purpose does the author write the text？C

8．Women might have a higher position at work，but at home their careers tend to give way to their husband's job，with women most likely to quit when both are working long hours，according to a U．S．study．
Researcher Youngjoo Cha，from Cornell University，found that working women with a husband who worked 50 hours or more a week found themselves still doing most of the housework and the care giving and were more likely to end up quitting their jobs．
An analysis of 8，484 professional workers and 17，648 nonprofessionals from dual-earner （双职工） families showed that if women had a husband who worked 60 hours or more per week it increased the woman's possibility of quitting her paid job by 42 percent．Cha said the possibility of quitting increased to 51 percent for professional women whose husbands work 60 hours or more per week，and for professional mothers the possibility they would quit their jobs jumped 112 percent．
However，it did not significantly affect a man's possibility of quitting his job if his wife worked 60 hours or more per week，according to the study published in the American Sociological Review in April．For professional men，both parents and non-parents，the effects of a wife working long hours were negligible，according to the study．
"As long work-hours introduce conflict between work and family into many dual-earner families，couples often solve conflict in ways that prioritize husbands'careers，"Cha，who used data from the U．S．Census Bureau，said in a statement．"This effect is magnified （突出） among workers in professional and managing occupations，where the criterion of overwork and the culture of looking after children tend to be strongest．The findings suggest that the popularity of overwork may lead many dual-earner couples to return to a traditional family pattern-breadwinning men and homemaking women．"
