According to a new US study，couples who expect their children to look after them in old age should hope they have daughters because daughters are twice as attentive as sons overall.
The research by Angelina Grigoryeva，from Princeton University，found that，while women provide as much care for their elderly parents as they can manage，men do as little as they can get away with and often leave it to female family members.
Her analysis of the family networks of 26,000 older Americans concluded that gender (性别) is one of the most important things that decide whether or not people will actively care for their elderly parents.
In a paper presented at the annual conference of the American Sociological Association in San Francisco，she concludes that simply having a sister makes men likely provide less care.
Using data from the University of Michigan Health and Retirement Study，a study which has been tracking a cross-section of over-50s for the last decade，she calculated that women provide an average of 12.3 hours a month of care for elderly parents while men offer only 5.6 hours.
“Sons reduce their relative care-giving efforts when they have a sister，while daughters increase theirs when they have a brother.”
“This suggests that sons pass on parent care-giving responsibilities to their sisters.”
In the UK，the 2011 Census showed that there are now around 6.5 million people with caring responsibilities，a figure which has risen by a tenth in a decade.
But many are doing so at the risk of their health.The census showed that those who provide 50 hours or more of care a week while trying to hold down a full-time job are three times more likely to be struggling with ill health than their working counterparts who are not carers.
语篇解读 本文是一篇说明文。研究表明，在照顾年爱迈的父母方面，性别差异影响着子女照顾父母时间的长短。其中，女儿比儿子更愿意付出时间照料年迈的父母。家中有姐妹的男士常常将照看老人的责任推给其姐妹。但是很多承担照顾老人的责任的子女自身都有潜在的健康问题。
1．According to the passage，what's the most important factor to predict if people will actively care for the elderly?
A．Education.
B．Gender.
C．Career. D．Income.
B [细节理解题。根据第三段中的“concluded that gender(性别)is one of the most important things that decide whether or not people will actively care for their elderly parents”可知，决定人们是否会主动照顾老年人的最主要因素是性别。故选B。]
2．The US study finds that________.
A. having a sister makes men less likely to look after their parents B．sons are twice as likely as daughters to care for parents in old age C．sons and daughters seem to give equal care to their parents
D．sons are unwilling to leave care-giving responsibilities to their sisters A [细节理解题。根据第四段可知，美国社会学家Angelina Grigoryeva得出结论，家中有姐妹的男士对父母的照顾可能会更少，与A项内容一致。故A项正确。]
3．What does the author stress in the last paragraph? A. People should give up their job to care for the elderly. B．Many care providers work longer hours than others. C．Many care providers have potential health problems. D．People shouldn't pass on caring responsibilities to others.
C [推理判断题。根据最后一段主题句“But many are doing so at the risk of their health.”及下文可知，在最后一段作者着重指出很多护理提供者都有潜在的健康问题。故选C。]
4．The author develops the text by________. A．explaining social networks of careers B．describing people's experiences C．comparing different gender behavior D．analyzing various researches and data
D [写作手法题。通读全文可知，作者在第三、五、八段给出了研究的数据，接着在相应数据段落的下一段分析得出结论。由此可推知，本文是以分析各种研究和数据得出相关结论的写作手法展开的。故选D。]
Ⅳ.任务型阅读
No one really knows how and why people change as they get older.__1__Aging is a complex and varied process that varies in how it affects different people and organs.In fact，even in one person，different organ systems “age” at different rates.
At a certain point in our lives our body systems will begin to weaken.__2__It may become more difficult for us to see and hear.The slow change of aging causes
our bodies to lose some of their ability to bounce back from disease and injury.In order to live longer，we have always tried to slow or stop this change that leads us toward the end of our lives.
__3__A good diet plays an important role.The amount and the type of exercise we get are another two factors.
__4__But scientists studying the aging problem want to know: why do people grow old? They hope that by studying the aging medical science they may be able to make the length of life longer.
__5__Many consider the later part of life to be the best time for living.Physical activity may become less，but often we get a better understanding of the world and ourselves.
What we consider the old age now may only be middle-aged some day soon.With so many advances in medical science happening so quickly，life length may one day be measured in centuries，rather than in years!
A. Our living condition is yet another. B．Many factors decide our health. C．Our strength may become weaker.
D．As for diet，people are advised to eat less salt and sugar. E There is nothing to be afraid of as the old age comes.
F．Symptoms include a lack of energy，slow reactions，insomnia (失眠) and poor memory.
G．Also，no theory sufficiently explains all the changes of the aging process. 语篇解读 没有人知道人在变老时的变化，饮食、锻炼等是决定健康的因素。许多人认为，人的后半生是人生的黄金时间，所以不要为衰老而恐惧。
1．G [根据空前一句“No one really knows how and why people change as they get older.”可知，选G项。G项中的“the changes of the aging process”与空前一句中的“change as they get older”对应。]
2．C [根据空处上一句中的“our body systems will begin to weaken”可知，随着年龄变大，我们的身体将开始衰弱；结合C项中的关键词“become weaker”可以判断，选C项。]
3．B [根据空后的“A good diet plays an important role.The amount and the type of exercise we get are another two factors.”可知，本段主要介绍了决定健康的几个因素，故选B项。]
4．A [根据空前的“another two factors”可知，选A项，说明另一个决定健康的因
