A research by the National Center for Health ...

A research by the National Center for Health Statistics is seen as an important confirmation of the“Hispanic mortality paradox（西班牙裔死亡率悖论）.”

On average，Hispanics outlive whites by 2.5 years and blacks by 7.7 years. Their life expectancy at birth in 2006 was 80.6 years，compared with 78.1 for whites，72.9 for blacks and 77.7 years for the total population.

The report shows that the Hispanic population has higher life expectancy at birth and at almost every age despite a socioeconomic status lower than that of whites.“Mortality is very correlated with income，education and health care access，”says Elizabeth Arias，author of the report.“You would expect the Hispanic population would have higher mortality，”in line with the black population.

The Hispanic paradox has been documented for more than two decades，but this is the first time the government has had enough data to issue national numbers. Researchers are struggling to explain why Hispanics live longer.

“We don’t know，”says David Hayes-Bautista，director of the Center for the Study of Latino Health and Culture at UCLA’s David Geffen School of Medicine.“We thought it was a problem in the data，but we can pretty much say this is real.”

Potential factors:

·Culture and lifestyle.  Support from extended family and lower rates of smoking and drinking.Latino groups in particular have very strong family and social ties.

·Migration.  The“healthy migrant effect”argues that healthy people are more likely to emigrate. And when immigrants become ill，they might return home and die there.

Solving the puzzle may help the nation deal with health care issues because Hispanics use health services less—they make fewer doctors visits and spend less time in hospitals，Hayes-Bautista says.“It’s clearly something in the Latino culture，”he says.

1.In 2006，Hispanics’life expectancy is ________ years longer than the average of the total population.

2.What does the underlined word“outlive”in the second paragraph probably mean？

3.What is the main idea of paragraph three？

4.What is Mr.Hayes-Bautista’s opinion about the paradox？

5.Which of the following inferences is true according to the passage？

According to figures released by the Office for National Statistics (ONS), the U.K. has about 7.7 million families with dependent children, of which 3.7 million have just one child, compared to 3 million with two and 1.1 million with three children or more. The number of families today with just one dependent child is now 47 percent and will likely rise to more than 50 percent in a decade. As the ONS confirms, “It appears that families are getting smaller.”

One obvious reason for this could be that women are putting off having children until they have established careers when they are bound to be less fertile. But it could just as well be a matter of choice. Parents must consider the rising cost of living, combined with economic uncertainty and an increasingly difficult job market. And this trend may continue growing as having an only child becomes more normal, which seems to be the mood on the mothers’ online forum Mumsnet, where one member announced that she “just wanted to start a positive thread about how fab it is to have an only child”.

She had received 231 replies, overwhelmingly in the same upbeat spirit. Parents of only children insist there are plenty of benefits. Nicola Kelly, a writer and lecturer who grew up as an only child and is now a married mother of one, says her 15-year-old son seems more grown-up in many ways than his contemporaries.

Not all products of single-child families are as keen to repeat the experience. In a moving recent account journalist Janice Turner wrote about her own keenness to “squeeze out two sons just 22 months apart” as a reaction to her only-child upbringing.

She was placed on a pedestal by her doting parents, whom she punished with a “brattish, wilful” rejection of everything they stood for. Desperate for a close friend she was repeatedly shattered by rejection and refers to her childhood as being “misery”.

Writer and clinician Dr. Dorothy Rowe, a member of the British Psychological Society, says that we all interpret events in our own individual way and there are some children who no matter what their circumstances feel slighted, while other children see the advantages of their situation.

However, the one part of life that is unlikely to get any easier for only children is when they grow up and find themselves looking after their own parents as they become older.

1.The passage is written with the purpose of ________.

A. illustrating the strength and weakness of having an only child

B. analyzing the reasons why having an only child becomes popular

C. presenting us with different opinions about having an only child

D. guiding people to look at the same issue from different perspectives

2.What does the underlined sentence in Paragraph 4 mean?

A. Nearly half of families intend to have just one child.

B. All people don’t stand for the idea of having an only child.

C. Some people fail to recognize the advantage of having an only child.

D. People brought up in an only child family resist downsizing the family.

3.From what Dr. Dorothy Rowe said, we know that ________.

A. journalist Janice Turner experienced a miserable childhood

B. she has a positive attitude towards Janice Turner’s reaction

C. it’s necessary for us to look at the event from our own angle

D. some are unable to make an objective assessment of their conditions

4.What can be inferred from the passage?

A. It’s normal to see the imperfection in character in only children.

B. Mumsnet is an online forum which promotes having an only child.

C. Economic development plays a determining role in the family size.

D. Only children will have difficulty in attending to their parents.

高三英语阅读理解中等难度题查看答案及解析

A research was carried out by the Associated Press-NORC Center for Public Affairs Research. It comes after a Chinese scientist claimed in November to have created the world’s first gene-edited human babies. More than 1,000 people were questioned in the study. The researchers said Americans value the medical promise of technology that could change the genetic qualities human parents pass on to their children. But they worry whether it will be used in a moral way.

Gene editing takes out a part of DNA to remove, replace or repair a gene. Changes to adult cells only affect the person being treated. But editing genes in eggs, sperm or embryos (胚胎) can change the resulting child in ways that can be passed to future generations. Because of its important effects, international science guidelines say gene-editing should not yet be tested in human pregnancies. Scientists say more laboratory research is needed to prove whether or not it is safe.

The AP-NORC study suggests that 71 percent of Americans approve of using gene editing to prevent deadly diseases, such as cystic fibrosis and Huntington’s disease. The study found that 65 percent of Americans would approve of using gene editing to prevent conditions such as blindness. There also was support for using the technology to reduce the risk of diseases that might develop later in life, such as cancer.

However, 66 percent of Americans oppose using gene editing to change qualities such as intelligence or athletic ability. They also oppose changing physical qualities such as eye color or height, the study found.

Dr. Robert Klitzman studies biological research rules. He noted that, if fertility clinics start to edit the genes of embryos, there will be hard choices to make about what conditions can be changed.

What if scientists could identify genes involved with depression or autism or high body weight? Would they be acceptable to edit? “It’s one thing to look at the extremes of fatal diseases versus cosmetic things, but in the middle are going to be these very different issues,” Klitzman said.

1.What can be learned about editing genes in embryos?

A.It can only affect the embryos being treated.

B.It will be completely safe to the embryos.

C.The effect can be passed to future generations.

D.It can be done without any laboratory research.

2.What did Klitzman worry about?

A.It’s difficult to decide what to change when editing genes.

B.It’ s hard for scientist to identify genes.

C.Gene editing will be used to prevent fatal diseases.

D.Gene editing is not supported by the government.

3.What can we conclude about the result of the research?

A.71% of Americans agree to use gene editing to prevent blindness.

B.Gene editing is a promising technology that should be widely used.

C.Americans approve of gene editing only for health purposes.

D.Most Americans are indifferent to the new technology.

4.What does the underlined word “autism” in the last paragraph refer to?

A.A kind of disease. B.An unhealthy baby.

C.A disabled person. D.A mood of happiness.

The 2014 Ranking of Top Universities in Greater China (RTUGC) is released today by the Center for World-Class Universities at Shanghai Jiao Tong University. RTUGC was the first attempt to compare top research universities in four regions of Great China, namely Mainland, Hong Kong, Macau and Taiwan.

Tsinghua University in Beijing remains No. 1 in the ranking. National Tsing Hua University in Taiwan overtakes National Taiwan University as the second. The Hong Kong University of Science and Technology climbs to 4th from 7th in 2013. Peking University remains in 5th place as it was in last year. Other Top 10 universities are: The University of Hong Kong, The Chinese University of Hong Kong, University of Science and Technology of China, National Chiao Tung University in Taiwan and Zhejiang University. The highest ranked university in Macau is University of Macau (54th).

RTUGC provides insight into the features and relative advantages of top universities in each region. Hong Kong and Macau universities show a higher degree of internationalization. The ranking highlights the fact that Mainland universities are stronger in gross(总的) performance while Hong Kong and Taiwan universities are in the lead in per capita(人均) performance. Tsinghua University in Beijing tops the list of annual research income, and The University of Hong Kong and City University of Hong Kong take the first place on research income per academic staff.

A recent study led by researchers from the National University of Singapore (NUS) has found a clear link between the color of a taxi and its accident rate. An analysis of 36 months of detailed taxi, driver and accident data from two fleets of yellow and blue taxis in Singapore suggested that yellow taxis have fewer accidents than blue taxis. The higher visibility (能见度) of yellow makes it less difficult for drivers to avoid getting into　 accidents with yellow taxis, leading to a lower accident rate.

The study was led by Prof Ho. To test whether there was a relationship between the color of a taxi and the number of accidents the taxi had, the research team analysed data collected by the largest taxi company in Singapore. The researchers found that yellow taxis have about 6. 1 fewer accidents per 1,000 taxis per month.

They also studied the economic effect of changing the color of the entire fleet of taxis to yellow. The Singapore taxi company involved in the study owns about 16,700 taxis in a ratio(比例) of one yellow to three blue taxis. If a commercial decision is made to switch from blue to yellow taxis, 76.6 fewer accidents will occur per month or 917 fewer accidents per year.

Assuming an average repair cost of $1,000 per car and a downtime of six days, the color of all taxis to yellow could produce an annual saving of $ 2 million.

“We are eager to continue to validate (证实) the findings of our study by looking at the use of yellow in other types of public transport, such as school buses. For example, we hope to compare the accident rates of yellow school buses against those of other colors to find out if yellow is indeed a safer color for school buses. Besides, we’re also interested to look at private-hire vehicles and do a comparison of the accident rates of vehicles that are of different colors.” Explained Prof Ho.

1.Why do yellow taxis result in fewer accidents?

A. Because yellow can be seen more easily.

B. Because yellow signals a warning of danger.

C. Because drivers tend to be more careful in yellow taxis.

D. Because people act more quickly in yellow surroundings.

2.What’s Prof Ho’s study based on?

A. Physical risks taxi passengers experience.

B. The economic effect of changing taxi color.

C. Data from Singapore’s largest taxi company.

D. Personal reports from taxi drivers worldwide.

3.What do Prof Ho’s words in the last paragraph suggest?

A. School buses should be painted yellow.

B. Their findings are worth popularizing.

C. Their study will be furthered.

D. Yellow should be widely used in public transport.

4.What can be the best title for the text?

A. Caution: yellow taxis ahead　　 B. Safer to ride in yellow taxis

C. Why are yellow taxis preferred?　　 D. How can colors help prevent accidents?
