题目内容

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.

A．2.5

B．7.7

C．2.9

D．80.6

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

3.What is the main idea of paragraph three？

A．Hispanics were born better than whites.

B．Morality is closely related with health care access.

C．Whites should have longer life expectancy.

D．Even experts can’t explain the phenomenon.

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

A．He supports there is a problem with the data.

B．He intends to trust the cultural factor.

C．He believes in the“healthy migrant effect”.

D．He thinks health care the most important factor.

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

A．Black people suffer the lowest social status in America.

Many people wonder why the United States has been a hotspot for Chinese students for years, despite its extremely strict visa policy. On the other hand, China’s rise as an economic powerhouse is resulting in a rapid expansion of its higher education system, making it the faster-growing destination for American foreign exchange students.

Recently, according to a study by the Institute of International Education, a research organization based in New York, the number of American students seeking higher education in China has never been greater, increasing by 90 percent from 2002 to 2004. Alan Goodman, president of the institute, believes that the phenomenon lies in the pace of change in China, which is spending billions of dollars to expend and transform its higher educational facilities into world-class institutions.

“China is a job market,” said Professor Chou, professor of East Asian Studies at Princeton University. “Twenty years ago, only those interested in Chinese literature would study Chinese language. Now all professors have opened up.”

China now ranks 9th as a host destination for American students, advancing from the No.12 spot it held a year earlier. The study revealed that Britain continues to be the leading destination, attracting 16.8 percent of all American students who study abroad. On the other hand, in the 2004-2005 academic year, China sent more than 62,000 students to the United States, nearly 60 percent more than a decade earlier. According to the study, the Chinese now make up 11 percent of foreign students in the United States, the second-largest group behind students from India.

41.From the first paragraph, we know that for many years Chinese students want to go to the US but _____.

A. Chinese government refuses to give a visa B. it is extremely difficult to get a visa

C. it results in a rapid expansion D. China becomes a fast-growing country

42.According to the text, “the phenomenon” in the second paragraph refers to _____.

A. more American students’ seeking higher education in China

B. the pace of change in China during the past few years

C. founding a research organization based in New York

D. expending and transforming its higher educational facilities

43.What is the main idea of this text?

A. American Students are looking for destination.

B. American students are interested in Chinese culture.

C. Britain continues to be the leading destination.

D. China grows as study hotspot for U.S. students.

One thing that every dog needs to know how to do is sit. Teaching a dog to sit is probably the easiest trick in the book. Dogs learn to sit by praise. You must first introduce them to what sitting is.

Gently place your hand over the top part of their bottoms and gently push down. Once you have got them into the sitting position, say “sit”. Now, make sure that they have sat down and give them a treat for praise. Wait a while before doing it again because each time you do it, you will be rewarding them for it.

Using treats while training your dog to sit will help him or her learn a lot easier. He or she might think, “Okay I get it, so when I sit, I get a treat!” So in the beginning, give your dog a treat every time they sit. At first, when you are training your dog to sit, they will feel puzzled. This is very normal because sitting is new to them. Dogs favor routine(常规), and once sitting becomes a part of their daily routine, it will be something that they truly enjoy doing for their owners when asked.

Young puppies are often the easiest to train to sit. Sitting is a simple and easy command that can be taught to any dog. Older dogs may learn a bit more slowly, but this is simply because they have got into much more of a routine. Do not think that your older dog cannot learn how to sit. It just takes time.

If you are having a seemingly difficult time teaching your dog to sit, you may need to go to your nearest library and rent a book on your particular dog family. Different dogs have different tempers. What is normal of one dog may not be so true for others. There are many things that will decide whether your dog has an easy time learning how to sit, but most of it will be up to you.

1. The most important thing in training a dog is _____

A. trick B. praise C. order D. treat

2. Young puppies are easier to train to sit because ______.

A. they are cleverer than older dogs

B. they haven’t got into much of a routine

C. they are different from old dogs in temper

D. they enjoy doing what their owners tell them to

3. We can know from the text that ______.

A. dogs, whether young or old, can be taught to sit only

B. dogs will sit when their owners pat them on the head

C. owners do not play an important part in training dogs to sit

D. different dogs should be treated differently when taught to sit

4. This text is probably taken from ______.

A. a travel journal B. a TV guidance C. a book about pets D. a research report

The eruption of a volcano in the Canary Islands could trigger a “mega-tsunami”（巨大海啸）that would hit Atlantic coastlines with waves as high as 330 feet, scientists said on Wednesday. They said an eruption of the Cumbre Vieja volcano on La Palma, part of the Spanish island chain off West Africa, was likely to cause a massive chunk（大块）of rock to break off, crashing into the sea and kicking up huge walls of water higher than any other in recorded history. The tsunami would be capable of traveling huge distances at up to 500 miles an hour, the scientists said in a research paper to be published soon.

Simon Day, of the Benfield Greig Hazard Research Centre at the University College of London, said that as the volcano was not erupting at present, the short-term and medium-term risks were “negligible”. But Cumbre Vieja should be monitored closely for any signs of activity so that emergency services could plan an effective response, he said. “Eruptions of Cumbre Vieja occur at intervals of decades to a century or so and there may be a number of eruptions before its collapse（倒塌）,” said Day, who cooperated on the research with Steven Ward of the University of California. “Although the year-to-year probability of a collapse is therefore low, the resulting tsunami would be a major disaster with indirect effects around the world.”

The effects would spread north, west and south of the Canaries, with the west Sahara bearing the worst of the wave’s energy. The energy released by the collapse would be equal to the electricity consumption of the entire United States in half a year.

Immediately after the landslide（山崩）,a huge wave of water 93,000 feet high and tens of miles wide would form. As the landslide rocks moved deeper under water, a tsunami would develop. Within 10 minutes, the tsunami would have moved a distance of almost 155 miles. On the west Saharan shore, waves would probably reach heights of 330 feet.

Florida and the Caribbean, the final north Atlantic destinations to be affected by the tsunami, would have to brace themselves for 165-foot waves some eight to nine hours after the landslide. Wave heights toward Europe would be smaller, but substantial waves would hit the coasts of Britain, Spain Portugal and France. The research paper estimated water would penetrate several miles inland and that the devastation would cause trillions of dollars in damage.

76. What would be the result of a big chunk rock falling into the sea?

A. Waves would be very high. B. The volcano would stop.

C. Walls of water would kick up a storm. D. An earthquake would take place.

77. The word “negligible”(Line 3, Paragraph 2) is closest in meaning to ______.

A. unimportant B. small C. predictable D. avoidable

78. From the passage we may learn that the volcano erupts ______.

A. every year B. every 5 to 9 years

C. every 10 to 100 years D. every 5 to 10 months

79. All of the following are true EXCEPT ______.

A future eruption of Cumbre Vieja volcano may experience a massive collapse

Waves generated by the landslide could even reach the coasts of the United States

The landslide-released energy is equal to half a year’s electricity consumption in the US

American scientists have managed to utilize the volcanic energy for civil purposes

Next time a customer comes to your office, offer him a cup of coffee. And when you’re doing your holiday shopping online, make sure you’re holding a large glass of iced tea. The physical sensation（感觉） of warmth encourages emotional warmth, while a cold drink in hand prevents you from making unwise decisions—those are the practical lesson being drawn from recent research by psychologist John A. Bargh.

Psychologists have known that one person’s perception（感知） of another’s “warmth” is a powerful determiner in social relationships. Judging someone to be either “warm” or “cold” is a primary consideration, even trumping evidence that a “cold” person may be more capable. Much of this is rooted in very early childhood experiences, Bargh argues, when babies’ conceptual sense of the world around them is shaped by physical sensations, particularly warmth and coldness. Classic studies by Harry Harlow, published in 1958, showed monkeys preferred to stay close to a cloth “mother” rather than one made of wire, even when the wire “mother” carried a food bottle. Harlow’s work and later studies have led psychologists to stress the need for warm physical contact from caregivers to help young children grow into healthy adults with normal social skills.

Feelings of “warmth” and “coldness” in social judgments appear to be universal. Although no worldwide study has been done, Bargh says that describing people as “warm” or “cold” is common to many cultures, and studies have found those perceptions influence judgment in dozens of countries.

To test the relationship between physical and psychological warmth, Bargh conducted an experiment which involved 41 college students. A research assistant who was unaware of the study’s hypotheses（假设）, handed the students either a hot cup of coffee, or a cold drink, to hold while the researcher filled out a short information form: The drink was then handed back. After that, the students were asked to rate the personality of “Person A” based on a particular description. Those who had briefly held the warm drink regarded Person A as warmer than those who had held the iced drink.

“We are grounded in our physical experiences even when we think abstractly,” says Bargh.

According to Paragraph 1, a person’s emotion may be affected by ______.

A. the visitors to his office B. the psychology lessons he has

C. his physical feeling of coldness D. the things he has bought online

The author mentions Harlow’s experiment to show that ______.

A. adults should develop social skills B. babies need warm physical contact

C. caregivers should be healthy adults D. monkeys have social relationships

In Bargh’s experiment, the students were asked to ______.

A. evaluate someone’s personality B. write down their hypotheses

C. fill out a personal information form

D. hold coffee and cold drink alternatively

We can infer from the passage that ______.

A. abstract thinking does not come from physical experiences

B. feelings of warmth and coldness are studied worldwide

C. physical temperature affects how we see others

D. capable persons are often cold to others

What would be the best title for the passage?
