According to a new US study, couples who expect their children to help care for them in old age should hope they have daughters because they are likely to be twice as attentive overall.
The research by Angelina Grigoryeva, a sociologist at 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 the most important predictor(预示物) of whether or not people will actively care for elderly parents.
In a paper being presented at the annual conference of the American Sociological Association in San Francisco, she concludes that simply having a sister makes men statistically 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.
“Whereas the amount of elderly parent care daughters provide is associated with limitations they face, such as employment or childcare, sons’caregiving is associated only with the presence or absence of other helpers, such as sisters or a parent’s spouse(配偶),” she explained.
“Sons reduce their relative caregiving efforts when they have a sister, while daughters increase theirs when they have a brother.”
“This suggests that sons pass on parent caregiving responsibilities to their sisters.”
In the UK, the 2011 census(人口普查) 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 own 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(相对应的人) who are not carers.What’s the most important factor to predict if people will actively care for the elderly?
| A．Gender. | B．Education. |
| C．Career. | D．Family networks. |
The US study finds that _______.
| A．sons are twice likely as daughters to care for parents in old age |
| B．having a sister makes men less likely to do their fair share |
| C．sons and daughters seem to give equal care to their parents |
| D．sons are unwilling to leave caregiving responsibilities to female family members |
What does the author stress in the last paragraph?
| A．People should give up their jobs to care for the elderly. |
| B．Many care providers work longer hours than others. |
| C．People shouldn’t pass on caring responsibilities to others. |
| D．Many care providers have potential health problems. |
The author develops the text by _______.

| B．describing people’s experiences |
| C．analyzing various research and data |
| D．comparing different gender behavior |
In a few years, you might be able to speak Chinese, Korean, Japanese, French, and English
— and all at the same time. This sounds incredible, but Alex Waibel, a computer science professor at US's Carnegie Mellon University (CMU) and Germany's University of Karlsruhe, announced last week that it may soon be reality. He and his team have invented software and hardware that could make it far easier for people who speak different languages to understand each other.
One application, called Lecture Translation, can easily translate a speech from one language into another. Current translation technologies typically limit speakers to certain topics or a limited vocabulary. Users also have to be trained how to use the programme.
Another prototype(雏形机) can send translations of a speech to different listeners depending on what language they speak. “It is like having a simultaneous translator right next to you but without disturbing the person next to you,” Waibel said.
Prefer to read? So-called Translation Glasses transcribe(转录) the translations on a tiny liquid-crystal(液晶) display(LCD) screen.
Then there’s the Muscle Translator. Electrodes capture the electrical signals from facial muscle movements made 
naturally when a person is mouthing words. The signals are then translated into speech. The electrodes could be replaced with wireless chips implanted in a person's face, according to researchers.
During a demonstration held last Thursday in CMU's Pittsburgh campus, a Chinese student named Stan Jou had 11 tiny electrodes attached to the muscles of his cheeks, neck and throat. Then he mouthed — without speaking aloud — a few words in Mandarin(普通话) to the audience. A few seconds later, the phrase was displayed on a computer screen and spoken out by the computer in English and Spanish: “Let me introduce our new prototype.”
This particular gadget(器械),when fully developed, might allow anyone to speak in any number of languages or, as Waibel put it, “to switch your mouth to a foreign language”. “The idea behind the university's prototypes is to create ‘good enough’ bridges for cross-cultural exchanges that are becoming more common in the world,” Waibel said.
With spontaneous(自发的) translators, foreign drivers in Germany could listen to traffic warnings on the radio, tourists in China could read all the signs and talk with local people, and leaders of different countries could have secret talks without any interpreters there. Which of the following statements is not TRUE?
| A．A lecture translation can translate what you said into other languages easily. |
| B．There is no Muscle Translator in the world now. |
| C．Muscle Translators can translate what you think into speech if you just move your mouth. |
| D．The spontaneous translators will help us a lot. |
What kind of equipment is NOT mentioned in this passage?
| A．Lecture Translation. |
| B．Muscle Translator. |
| C．Multiple Translator. |
| D．Translation Prototype. |
What’s the final destination of inventing the language translators?
| A．To make cultural exchanges between different countries easier. |
| B．To help students learn foreign languages more easily. |
| C．To make people live in foreign countries more comfortably. |
| D．To help people learn more foreign languages in the future. |
What can
be inferred from the seventh paragraph?
| A．The translator is so good that it can translate any language into the very language you need. |
| B．The translator is becoming more and more common in the world as a bridge. |
| C．With the help of the translator, you only need to open your mouth when you want to say something without saying the exact words at all. |
| D．The translator needs to be improved before being put into market. |
Where can this passage probably be excerpted from?
| A．A newspaper. |
| B．A magazine on science. |
| C．A fairy tale. |
| D．A scientific fantasy book. |
The way people hold to the belief that a fun-filled, pain free life equals happiness actually reduces their chances of ever attaining real happiness. If fun and pleasure are equal to happiness then pain must be equal to unhappiness. But in fact, the opposite is true: more often than not things that lead to happiness involve some pain.
As a result, many people avoid the very attempts that are the source of true happiness. They fear the pain inevitably brought by such things as marriage, raising children, professional achievement, religious commitment（承担的义务）, self - improvement.
Ask a bachelor（单身汉） why he resists marriage even though he finds dating to be less and less satisfying. If he is honest he will tell you that he is afraid of making a commitment. For commitment is in fact quite painful. The single life is filled with fun, adventure, excitement. Marriage has such moments, but they are not its most distinguishing features.
Couples with infant children are lucky to get a whole night’s sleep or a three - day vacation. I don’t know any parent who would choose the word fun to describe raising children. But couples who decide not to have children never know the joys of watching a child grow up or of playing with a grandchild.
Understanding and accepting that true happiness has nothing to do with fun is one of the most liberati
ng realizations. It liberates time: now we can devote more hours to activities that can genuinely increase our happiness. It liberates money: buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless. And it liberates us from envy: we now understand that all those who are always having so much fun actually may not be happy at all.According to the author, a bachelor resists marriage chiefly because ____________ .
| A．he is reluctant to take on family responsibilities |
| B．he believes that life will be more cheerful if he remains single |
| C．he finds more fun in dating than in marriage |
| D．he fears it will put an end to all his fun adventure and excitement |
Raising children, in the author’s opinion is ____________ .
| A．a moral duty |
| B．a thankless job |
| C．a rewarding task |
| D．a source of inevitable pain |
From the last paragraph, we learn that envy sometimes stems from ____________ .
| A．hatred |
| B．misunderstanding |
| C．prejudice |
| D．ignorance |
To understand what true happiness is one must ____________ .
| A．have as much fun as possible during one’s lifetime |
| B．make every effort to liberate oneself from pain |
| C．put up with pain under all circumstances |
| D．be able to distinguish happiness from fun |
What is the author trying to tell us?
| A．Happiness often goes hand in hand with pain． |
| B．One must know how to attain happiness. |
| C．It is important to make commitments. |
| D．It is pain that leads to happiness. |
Everywhere man is altering the balance of nature．He is facilitating the spread of plants and animals into new regions, sometimes deliberately, sometimes unconsciously．He is covering huge areas with new kinds of plants, or with houses, factories, slag-heaps and other products of his civilization．He exterminates some species on a large scale, but favors the multiplication of others．In brief, he has done more in five thousand years to alter the biological aspect of the planet than has nature in five million．
Many of these changes which he has brought about have had unforeseen consequences．Who would have thought that the throwing away of a piece of Canadian waterweed would have caused half the waterways of Britain to be blocked for a decade, or that the provision of pot cacti for lonely settlers’ wives would have led to Eastern Australian being overrun with forests of Prickly Pear? Who would have prophesied that the cutting down of forests on the Adriatic coasts, or in parts of Central Africa, could have reduced the land to a semi desert, with the very soil washed away from the bare rock? Who would have thought that improved communications would have changed history by the spreading of disease-sleeping sickness into East Africa, measles into Oceania, very possibly malaria into ancient Greece?
These are spectacular examples; but examples on a smaller scale are everywhere to be found．We make a nature sanctuary for rare birds, prescribing absolute security for all species; and we may find that some common and hardy kind of bird multiplies beyond measure and ousts the rare kinds in which we were particularly interested．We see, owing to some little change brought about by civilization, the starling spread over the English country-side in hordes．We improve the yielding capacities of our cattle; and find that now they exhaust the pastures which sufficed for less exigent stock．The following examples except _______________ reflect man altering the balance of nature．
| A．man is covering huge areas with new kinds of plants |
B．man is fa cilitating the spread of animals into new regions． |
| C．man is killing some species on a large scale |
| D．man is getting to know the importance of keeping the balance of nature． |
What had a piece of Canadian waterweed cause?
| A．Eastern Australian was overrun with forests． |
| B．Half the waterways of Britain blocked for a decade． |
| C．In parts of central Africa, the land reduced to a semi desert． |
| D．Disease-sleeping has been caused． |
What have spread diseases?
| A．Disease-sleeping sickness． | B．Measles． |
| C．Improved communications． | D．Malaria． |
We make a nature sanctuary for rare birds but _______________.
| A．some common and hardy kind of bird multiplies |
| B．rare kinds multiply |
| C．all bird multiply |
| D．no bird multiply |
The main idea of the passage is ______________．
| A．that man is deliberately destroying the balance of nature |
| B．that man has foreseen the consequences of altering the balance old nature |
| C．that improved communications have changed history |
| D．that man is altering the balance of nature |
Microwaves may be great at warming up food, but what about warming people?
Using microwaves to directly heat owners of
a room would save much of the energy wasted by heating walls and furniture. And despite popular ideas about microwaves, this techniqu
e would be safe, according to Charles R. Burlier of the Microwave Research Center in Marlborough, New Hampshire. Low-power microwaves only penetrate (贯穿) the skin (low-power microwave penetration in a ham is about 0.2 inches, for example) and with no negative effects.
To test this idea, Buffler subjected himself to microwaves in a special room using a standard 500-watt, 2459 MHz magnetron (磁控管). He found that a person will start to feel warmth at about 20 kilowatts per square centimeter (mw. / sq. cm. ) ; a satisfactory feeling of warmth occurs between 35 and 50 mw. / sq. cm. By comparison, a person standing in noonday summer sun feels the amount of 85 mw. / sq. cm. And a frozen meat pie in your microwave oven receives about 1000 mw. / sq. cm.
In houses of the future, each room could be provided with its own magnetron, says Buffler. When you stepped into the living room, for example, a motion detector (运动感应器)would turn on the magnetron, filling the room with low-power microwaves. In the same way that a microwave oven heats up a hamburger, but not the plate it’s on, you would feel warmth from the microwaves without changing the temperature of your coffee table. (You could, however, make your favorite easy chair even more comfortable by treating it with a radiation-absorbing chemical.)
While it might be some time before homeowners are comfortable enough with the idea to set up whole-body microwave heaters in houses, Buffler says microwaves may attract livestock(家畜) farmers. Lambs that are born outdoors in winter, for example, are frequently lost to cold. Microwaves could warm the lambs safely and quickly. Which of the following can tell the main idea of the passage?
| A．A new heating system. |
| B．A new microwave oven. |
| C．A popular technique. |
| D．The magnetron. |
According to Paragraph 2, which of the following does not describe the characteristics of a microwave heater?
| A．It directly heats people in a room. |
| B．It heats walls and furniture in a room. |
| C．It is safe. |
| D．It saves energy． |
The test conducted by Buffler shows that when a person feels comfortable warmth, he receives about ________________.
| A．20 mw. / sq. cm. | B．40 mw. / sq. cm. |
| C．60 mw. / sq. cm. | D．85 mw. / sq. cm. |
According to Paragraph 4, which of the following fills the room with low-power microwaves?
| A．The magnetron. |
| B．The motion detector. |
| C．The microwave oven. |
| D．The radiation-absorbing chemical. |
Which of the following statements about
microwave heaters would Buffler most probably agree with?
| A．Microwave heaters will soon be widely used by homeowners. |
| B．Microwave heaters sometimes make people feel uncomfortable. |
| C．Perhaps microwave heaters will be first used by livestock farmers, who wish to protect their lambs in winter. |
| D．Microwave heaters cannot be accepted by the public because they are somewhat unsafe. |
People fell in love with Elizabeth Taylor in 1944, when she starred in National Velvet-the story of Velvet Brown, a young girl who wins first place in a famous horse race, At first, the producers of the movie told Taylor that she was too small to play the part of Velvet. However, they waited for her for a few months as she exercised and trained—and added three inches to her height in four months! Her acting in National Velvet is still considered the best by a child actress.
Elizabeth Taylor was born in London in 1932. Her parents, both Americans, had moved there for business reasons. When World War II started, the Taylors moved to Beverly Hills, California, and there Elizabeth started acting in movies. After her success as a child star, Taylor had no trouble moving into adult(成人)roles and won twice for Best Actress: Butterfield 8(1960) and Who’s Afraid of Virginia Woolf ? (1966)
Taylor’s fame(名声)and popularity gave her a lot of power with the movie industry, so she was able to demand very high pay for her movies. In 1963, she received $1 million for her part in Cleopatra—the highest pay r
eceived by any star up to that time.
Elizabeth Taylor is a legend (传奇人物) of our time. Like Velvet Brown in National Velvet, she has been lucky, she has beauty, fame and wealth. But she is also a hard worker. Taylor seldom acts in movies any more. Instead, she puts her time and efforts into her businesses, and into helping others — several years ago, she founded an organization that has raised more than $40 million for research and education. The producers didn’t let Taylor play the part of Velvet at first because they thought she ____.
| A．was small in size | B．was too young |
| C．did not play well enough | D．did not show much interest |
What Elizabeth Taylor and Velvet Brown had in common was that they were both _____.
| A．popular all their lives | B．famous actresses |
| C．suecessful when very young | D．rich and kind-hearted |
Taylor became Best Actress at the age of .
| A．12 | B．28 | C．31 | D．34 |
In her later life , Elizabeth Taylor devoted herself to .
| A．doing business and helping others | B．turning herself into a legend |
| C．collecting money for the poor | D．going about research and education work |
