B
Having a husband means an extra seven hours of housework each week for women, according to a new study. For men, getting married saves an hour of housework a week. “It’s a well-known pattern,” said lead researcher Frank Stafford at University of Michigan’s Institute for Social Research. “Men usually work more outside the home, while women take on more of the housework.”
He points out that differences among households（家庭）exist. But in general, marriage means more housework for women and less for men. “And the situation gets worse for women when they have children,” Stafford said.
Overall, times are changing in the American home. In 1976, women busied themselves with 26 weekly hours of sweeping-and-dusting work, compared with 17 hours in 2005. Men are taking on more housework, more than doubling their housework hours from six in 1976 to 13 in 2005.
Single women in their 20s and 30s did the least housework, about 12 weekly hours, while married women in their 60s and 70s did the most-about 21 hours a week.
Men showed a somewhat different pattern, with older men picking up the broom more often than younger men. Single men worked the hardest around the house, more than that of all other age groups of married men.
Having children increases housework even further. With more than three children, for example, wives took on more of the extra work, clocking about 28 hours a week compared with husbands’10 hours.
45. According to the “well-known pattern” in Paragraph 1, a married man___________.
A. takes on heavier work B. does more housework
C. is the main breadwinner D. is the master of the house

A New Strategy to Overcome Breast Cancer
Post-menopausal（绝经后的）women who walk for an hour a day can cut their chance of breast cancer significantly,a study has suggested.The report,which followed 73,000 women for 17 years,found walking for at least seven hours a week lowered the risk of the disease.The American Cancer Society team said this was the first time reduced risk was specifically linked to walking.UK experts said it was more evidence that lifestyle influenced cancer risk.
A recent poll for the charity Ramblers found a quarter of adults walk for no more than an hour a week, but being active is known to reduce the risk of a number of cancers.This study,,published in Cancer Epidemiology,Biomarkers&Prevention,followed 73,615 women out of 97,785 aged 50-74 who had been recruited by the American Cancer Society between 1992 and 1993,so it could monitor the incidence of cancer in the group.
They were asked to complete questionnaires on their health and on how much time they were active and participating in activities such as walking , swimming and aerobics（有氧运动）and how much time they spent sitting,watching television or reading.They completed the same questionnaires at, two-year intervals between 1997 and 2009.Of the women,47%said walking was their only recreational activity.Those who walked for at least seven hours per week had a 14%lower risk of breast cancer compared to those who walked three or fewer hours per week.
Dr.Alpa Patel,a senior epidemiologist at the American Cancer Society in Atianta Georgia,who led the study,said:"Given that more than 60% of women report some daily walking,promoting walking as a healthy leisure-time activity could be an effective strategy for increasing physical activity amongst post-menopausal women.We were pleased to find that without any other recreational activity,just walking one hour a day was associated with a lower risk of breast cancer in these women." " More strenuous（紧张的） and longer activities lowered the risk even more."
Baroness Delyth Morgan,chief executive of Breast Cancer Campaign,said:"This study adds further evidence that our lifestyle choices can play a part in influencing the risk of breast cancer and even small changes incorporated into our normal day-to-day activity can make a difference."
She added:"We know that the best weapon to overcoming breast cancer is the ability to stop it occurring in the first place.The challenge now is how we turn these findings into action and identify other sustainable lifestyle changes that will help us prevent breast cancer."Which of the following statements is true according to the passage?
A:Most women take walking as their only recreational activity.
B:The study aims to track the health conditions of its subjects.
C:Irregular walking increased the risk of breast cancer in post-menopausal women.
D:Walking was the only recreational activity for about half of the women surveyed.答案：D解析：本文主要讲述的内容为每周至少7个小时的散步能够降低女性患乳腺癌的几率。并且通过进行实验证明了这一点，最后还指出生活方式的变化对抑制乳腺癌的发生有重要的影响。
A项在文章第一段第二句中便提及到。C项在文章第三段和第四段均有提及。第五段中Baroness Delyth Morgan的讲话内容和D项内容吻合，而B项在本文中未提及，故选B。
由文章第四段中的“We were pleased to find that without any other...”这句话可知，每天一个小时的散步能够降低乳腺癌发生的几率，故选A。
由文章第四段第一句可知，此次研究是由Dr.Alpa Patel领导的，故选D。
由文章第三段第三句可知，有47%的被调查女性称散步是她们唯一的消遣活动，其他三项均与原文内容不符，故选D。
由文章上下文内容可知，此处的sustainable lifestyle指的是一种可持续的生活方式： sustainable和选项中的continuable均有“可持续的”之义，故选D。 -
第6题：
Text 3 Family caregivers provide essential,often unpaid work in the U.S.:they help family members with tasks like bathing and eating,coordinating insurance coverage and managing medications.But what a caregiver looks like in America is changing.Although the typical unpaid family caregiver is a 49-year-old white woman,about 10 million Americans between ages 18 and 34,of all different backgrounds,are now the caregivers for a family member or friend,according to a new report by AARP.One out of four family caregivers in the U.S.is a millennial.And as Baby Boomers age and need more support,this young group is becoming an increasingly important part of the caregiving workforce.More than half of millennial caregivers are now people of color,according to the report,and they are more likely than any other generation to balance caregiving with employment.Nearly three quarters of millennial caregivers are employed,according to the new report,and 53%work full time.They also spend an average of 21 hours per week on caregiving,or the equivalent of a part time job.More than one in four millennials spends over 20 hours each week providing care,and roughly one in five provides care for at least 40 hours each week."Many of these millennials are not just working and providing this care,but are trying to figure out,ihow do I balance all of this?"'says Jean Accius,an expert on long-term care services and supports at the AARP's public policy institute,which provides guides for different communities of caregivers."At this time in their life,a typical milleruual may be thinking about going on vacation,hanging out with friends and potentially getting married,but these millennials are doing things like wound care and bathing."The report finds that Latino millennials often face increased pressure,as they work more hours each week on average and spend more time providing care than young adults of other backgrounds.Some of this has to do with the fact that Hispanuc Americans are more likely to live in multi-generational households,Accius says.Tasks like navigating govemment health systems or coordinating care between multiple providers can also be particularly challenging for families that have members whose first language is not English.Another common source of stress is the impact that caregiving responsibilities can have on a person's career.54%of millennial caregivers say that caregiving has impacted their job in significant ways,according to the report.Yet millennials are much less likely to tell their supervisors or colleagues at work about their caregiving responsibilities,meaning they are often navigating alone.One sign of progress is that millennial men are nearly as likely to provide care as women,according to the report."The way that millennials think about gendered work or gendered care roles is changing,"says Whiting."The U.S.is already facing a shortage of caregivers,and the increasing gender and racial diversity of millennial caregivers will be necessary to support all those who need help in the future:'she says."We see,especially among millennials,that everybody bears some responsibility,and we need to care for each other."
According to AARP,family caregivers in America_____A.are limited to white women
B.are usually without payment
C.are more younger than before
D.are paid by their friends答案：C解析：事实细节题。根据定位词定位到文章第一段。报告指出，年龄在18岁到34岁之间的美国人也加入了护理人员行列，而与通常的无偿家庭护理人员为一位49岁的白人女性相比，他们更年轻，故C项为正确选项。【干扰排除】原文提到通常的无偿家庭护理人员是一位49岁的白人女性，并未提到局限于白人女性，A项错误；B项所述并非报告中的内容；D项原文未提及。故均排除。 -
第7题：
Everyone becomes a little more forgetful as they get older, but men's minds decline more than women's, according to the results of a worldwide survey.
Certain differences seem to be inherent in male and female brains: Men are better at maintaining and dealing with mental images (useful in mathematical reasoning and spatial skills ) , while women tend to excel (擅长) at recalling information from their brain's files (helpful with language skills and remembering the locations of objects).
Many studies have looked for a connection between sex and the amount of mental decline ( 衰退) people experience as they age, but the results have been mixed.
Some studies found more age-related decline in men than in women, while others saw the opposite or even no relationship at all between sex and mental decline．Those results could be improper because the studies involved older people, and women live longer than men: The men tested are the survivors, "so they're the ones that may not have shown such cognitive decline," said study team leader Elizabeth of the University of Warwick in England.
People surveyed completed four tasks that tested sex-related cognitive skills: matching an object to its rotated form, matching lines shown from the same angle, typing as many words in a particular category (范畴) as possible in the given time, e.g．"object usually colored gray", and recalling the location of objects in a line drawing．The first two were tasks at which men usually excel; the latter were typically dominated by women.
Within each age group studied, men and women performed better in their separate categories on average．And though performance declined with age for both genders, women showed obviously less decline than men overall.
Which of the following statements is TRUE according to the article?A.Men do better than women when it comes to learning English.
B.Women stand out at remembering people's names.
C.Men excel at typing as many words in a particular category as possible in the given time.

第14题：
阅读理解Betty and Harold have been married for years.But one thing still puzzles old Harold.How is it that he can leave Betty and her friend Joan sitting on the sofa, talking, go out to a ballgame, come back three and a half hours later, and they’re still sitting on the sofa, talking?
What in the world, Harold wonders, do they have to talk about?
Betty shrugs.Talk? We’re friends.
Researching this matter called friendship, psychologist Lillian Rubin spent two years interviewing more than two hundred women and men.No matter what their age, their job, their sex, the results were completely clear.Women have more friendships than men, and the difference in the content and the quality of those friendships is “marked and unmistakable”.
More than two-thirds of the single men Rubin interviewed could not name a best friend.Those who could were likely to name a woman.Yet three-quarters of the single women had no problem naming a best friend, and almost always it was a woman.More married men than women named their wife/husband as a best friend, most trusted person, or the one they would turn to in time of emotional distress(情感危机).“Most women,” says Rubin, “identified at least one, usually more, trusted friends to whom they could turn in a troubled moment, and they spoke openly about the importance of these relationships in their lives”.
“In general,” writes Rubin in her new book, “women’s friendships with each other rest on shared emotions and support, but men’s relationships are marked by shared activities.” For the most part, Rubin says , interactions (交往) between men are emotionally controlled—a good fit with the social requirements of “manly behavior”.
“Even when a man is said to be a best friend,” Rubin writes, “the two share little about their innermost feelings.Whereas a woman’s closest female friend might be the first to tell her to leave a failing marriage, it wasn’t unusual to hear a man say he didn’t know his friend’s marriage was in serious trouble until he appeared one night asking if he could sleep on the sofa.”
6.What old Harold cannot understand or explain is the fact that() .
A.he is treated as an outsider rather than a husband
B.women have so much to share
C.women show little interest in ballgames
D.his wife is difficult to talk to
7.Rubin’s study shows that for emotional support a married woman is more likely to turn to ().
A.a male friend
B.a female friend
C.her parents
D.her husband
8.According to the text, which type of behavior. is NOT expected of a man by society?()
A.Ending his marriage without good reason.
B.Spending too much time with his friends.
C.Complaining about his marriage trouble.
D.Going out to ballgames too often.
9.Which of the following statements is best supported by the last paragraph?()
A.Men keep their innermost feeling to themselves.
B.Women are more serious than men about marriage.
C.Men often take sudden action to end their marriage.
D.Women depend on others in making decisions.
10.The research done by psychologist Rubin centers on() .
A.happy and successful marriage
B.friendships of men and women
C.emotional problems in marriage
D.interactions between men and women

It is frequently assumed that the mechanization of work has a revolutionary effect on the livesof the people who operate the new machines and on the society into which the machines have beenintroduced. For example, it has been suggested that the employment of women in industry takethem out of the. household, their traditional sphere and fundamentally alter their position in society.In the nineteenth century, when women began to enter factories, Jules Simon, a French politician,warned that by doing so, women would give up their femininity. Fredrich Engels, however,predicted that women would be liberated from the"social, legal, and economic subordination" ofthe family by technological developments that made possible the recruitment of "the whole femalesex .., into public industry." Observers thus differed concerning the social desirability ofmechanization's effects, but thev agreed that it would trmsiorm women's lives.
Historians, particularly thnse investigating the history of women, now seriously question thisassumption of transforming power. They conclude that such dramatic technological innovations asthe spinning jenny, the sewing tnachine, the typewriter, and the vacuum cleaner have not resultedin equally dramatic social changes in women's economic position or in the prevailing evaluation ofwomen's work. The employment of young women in textile mills during the Industrial Revolutionwas largely and extension of an older pattern of employment for young, single women as domestics.It was not the change in office technology, but rather the separation of secretarial work, previouslyseen as an apprenticeship for beginning managers, from administrative work that in the 1880'screated a new class of "dead end" jobs, thenceforth considered "women's work". The increase inthe numbers of married women enployed outside the home in the twentieth century, had less to dowith the mechanization of housework and an increase in leisure time for these women than it didwith their own economic necessity and with high marriage rates that shrank the available pool ofsingle women worke, previously, in many cases, the only women employers would hire.
Women's work has changed considerably in the past 200 years, moving from the household tothe ofiice or the factory, and later becoming mostly white-collar instead of blue-collar work. Fundamentally, however, the conditions under which women work have changed little since the Industrial Revolution: the segregation of occupatious by gender, lower pay for women as a group,jobs that require relatively low levels of skill and offer women little opportunity for advancement all persist, while women's household labour remains demanding. Recent historical investigation has led to a major revision of the notion that lec.hnology is always inherently revolutionary in its effectson society. Mechanization may even have slowed any change in the traditional position of womeu both in the labour market and in the home.
Why did the numbers of married women employers increase in the 20th century?
查看材料A．The mechanization of housework.
B．The married women have much spare time.
C．The employers don't want to hire the single women.
D．Because of their own economic uecessity and high marriage rates.答案：D解析：根据题于中的“the numbers ofmarried women employers increase in the 20th century,’可定位至第二段末句“llle increase in the numbers of married women employed outside the home in the twentieth century had less to do with the mechanization of housework and an increase in leisure time for these women than it did with their own economic necessity and with high marriage rates that shrank the available pool of single women workers，previously，in many cases，the only women employers would hire．”由此可知，20世纪已婚妇女职员的增加是因为她们经济上的必需性，以及结婚率的升高。D项符合。 -

Just one hour's listening to an MP3 player can damage hearing,claim scientists.It causes temporary changes in hearing sensitivity which may lead to long-term harm,according to a new study.
The findings show over -stimulation of hair cells within the ear occurs even at varying volume levels for short periods of time.The study of almost 60 young people carried out by researchers at Ghent University,Belgium,is published in the Archives of Otolaryngology -Head&Neck Surgery journal.
It follows previous warnings from doctors that using MP3 players at high volumes with earphones that fit into the ear canal could lead to loss of hearing. In the latest study,21 people aged 19 to 28 years were exposed to pop and rock music using MP3 players at varying volumes for one hour. A second group of 28 men and women were a control group who were not exposed to MP3 music.
Hearing tests were carried out before and after the exposure,which found significant threshold or emission shifts were observed between almost every session of the noise exposure group compared with the control group.Lead researcher Hannah Kempler said:Excessive noise exposure can lead to metabolic and mechanical effects resulting in alterations of the structural elements of the inner ear that contains auditory sensory cells or"hair cells".
The European Commission has warned up to 10% of 30-year-old would have to wear a hearing device within the next decade because they listen to music too loudly through headphones.Surveys showed more than 90% of young people in Europe and the U.S.used MP3 players,often for several hours a day at maximum volume.Hearing experts recommend the 60/60 rule一listening to MP3 players for no more than 60 minutes at a time at 60% of maximum volume.Concern among EU health and safety officials has led to plan to ensure all MP3 players have the same maximum volume of 85 decibels(dB)一although users may be able to individually override it at their own risk.According to the surveys,most young people in both Europe and the U.S.used MP3 players for too long hours at maximum volume.
A:Right
B:Wrong
C:Not mentioned答案：A解析：通过MP3播放器听60分钟的音乐不会损伤人的听力。根据是第一段第一句：Just one hour's listening to an MP3 player can damage hearing, claim scientists．科学家说，听 MP3哪怕只是短短一小时也有可能会损害听力。因此该句话是错误的。
这项新研究的研究结果和早前医生对于戴着耳机调高音量听MP3的危险的警告不谋而合。根据是第三段第一句：It follows previous warnings from doctors that using MP3 players at high volumes with earphones that fit into the ear canal could lead to loss of hearing．在此之前有医生警告说戴耳机听MP3时音量开得太高会导致耳聋。因此该句话是正确的。
对照组指的是短时间听MP3的人。根据是第三段最后一句：A second group of 28 men and women were a control group who were not exposed to MP3 music．另外一组中的28名男女作为对照组则没有听MP3播放的音乐。因此该句话是错误的。
根据听MP3之后的听力测试，对照组和收听组之间没有发现太多的差别。根据是第四段第一句：Hearing tests were carried out before and after the exposure, which found significant threshold or emission shifts were observed between almost every session of the noise exposure group compared with the control group．在听音乐前后分别进行了听力测试，结果发现几乎每次都能够在噪音接触组和对照组之间观察到重要的临界点和发出声音的变化。因此该句话是错误的。
据调查，欧美大多数年轻人将音量调到最高收听MP3的时间都过长。根据是第五段第二句：Surveys showed more than 90% of young people in Europe and the U.S.used MP3 players, often for several hours a day at maximum volume．研究表明，欧洲和美国超过90% 的年轻人使用MP3，而且经常每天将音量开至最大连续听数小时。因此该句话是正确的。
在60/60原则中，第二个60指的是最高音量的60%。根据是第五段第三句：Hearing experts recommend the 60/60 rule一listening to MP3 players for no more than 60 minutes at a time at 60% of maximum volume．听力专家建议60/60原则即每次听MP3时间不超过 60分钟，音量调节为最大音量的60%。因此该句话是正确的。
由最后一段最后一句Concern among EU health and safety officials has led to plan to ensure all MP3 players have the same maximum volume of 85 decibels(dB)一although users may be able to individually override it at their own risk．可知，是欧洲委员会健康和安全部门的官员们，已经出台了计划将所有MP3播放器的最高音量统一设定为85分贝，而不是MP3的生产厂家已将最高音量设为85分贝。故题中说法错误。 -

Everyone becomes a little more forgetful as they get older, but men's minds decline more than women's, according to the results of a worldwide survey.
