A recent study of ancient and modern elephants has come up with the unexpected conclusion that the African elephant is divided into two distinct (不同的) species
The discovery was made by researchers at York and Harvard universities when they were examining the genetic relationship between the ancient woolly mammoth and mastodon to modern elephants—the Asian elephant, African forest elephant and African savanna elephant
Once they obtained DNA sequences (序列) from two fossils (化石)，mammoths and mastodons the team compared them with DNA from modern elephants. They found to their amazement that modern forest and savanna elephants are as distinct from each other as Asian elephants and mammoths.
The scientists used detailed genetic analysis to prove that the African savanna elephants and the African forest elephants have been distinct species for several million years. The divergence of the two species took place around the time of the divergence of Asian elephants and woolly mammoths. This result amazed all the scientists.
There has long been debate in the scientific community that the two might be separate species but this is the most convincing scientific evidence so far that they are indeed different species.
Previously, many naturalists believed that African savanna elephants and African forest elephants were two populations of the same species despite the elephants’ significant size differences. The savanna elephant has an average shoulder height of 3.5metres while the forest elephant has an average shoulder height of 2.5metres. The savanna elephant weighs between six and seven tons, roughly double the weight of the forest elephant. But the fact that they look so different does not necessarily mean they are different species. However, the proof lay in the analysis of the DNA.
Alfred Roca, assistant professor in the department of Animal Sciences at the University of Minois, said, “We now have to treat the forest and savanna elephants as two different units for conservation purpose. Since 1950 all African elephants have been conserved as one species. Now that we know the forest and savanna elephants are two very distinct animals, the forest elephant should become a bigger priority (優先)for conservation purpose .”

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(感覺) 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(假設), 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?
A. Drinking for Better Social Relationships.
B. Experiments of Personality Evaluation.
C. Developing Better Drinking Habits.
D. Physical Sensations and Emotions.

A recent Living Social survey showed that Americans may live up to their poor reputation while travelling abroad. But what’s more surprising is that many of those surveyed self-identified themselves as ‘ugly’ Americans and the world’s worst travelers.
Those in the U.S. ranked themselves as the worst travellers by a shocking 20 per cent, followed by 15 per cent saying the Chinese were the most substandard tourists.
Americans topped the list as being the worst-behaved travelers in a survey of 5,600 respondents, 4,000 of whom were Americans. Other respondents were in Australia, Canada, Ireland and the United Kingdom. But even American respondents considered their compatriots(同胞) as the worst travelers from a list of 16 nationalities.
Canadians and Australians also put Americans in the No. 1 spot. Irish respondents pointed to U.K. residents and U.K. respondents gave Germans the nod. On the other hand, 37% of Americans opted for "none of the above" in answer to the worst-tourists question, displaying more tolerance and open-mindedness than the other nationalities.
Other survey questions had respondents admitting pilfering from hotels. Four in ten U.S. survey-takers said they’d stolen something – mostly towels (28%) and bathrobes (8%). Other popular pinched items included pillows, remote controls, Bibles and sheets.
Not surprising is that Americans have less time off from work than other nationalities. Americans reported getting 16 days off, compared with 28 days for the Irish, 27 days for Australians, 23 days for U.K. workers; and 21 days for Canadians.
In the travel mishaps department, the most common travel disaster reported by Americans was lost luggage on an airline (21%)； bad weather (21%)； and getting very lost (16%).
As for places Americans most want to see, Disney World and Las Vegas made the top 10, but they weren't at the top of the heap. And New York didn't make the cut.
1.What percentage of American respondents is in the survey?
|
A．20 % |
B．15% |
C．71% |
D．37% |
2.The underlined word “pilfering” in Para. 5 most probably means ________.
|
A．taking |
B．bringing |
C．stealing |
D．borrowing. |
3.According to the survey, what kind of things are most taken away by Americans?
|
A．towels and pillows |
|
B．bathrobes and remote controls. |
|
C．towels and Bibles |
|
D．bathrobes and towels. |
4.What’s the best title of this passage?
|
A．Chinese were announced as the world’s worst travellers. |
|
B．The global worst travellers were announced. |
|
C．Disney World is the best destination to Americans. |
|
D．European travellers were the best in the world |

閱讀下面的短文，請根據短文后的要求答題（請注意問題后的詞數要求）。
[1]Global difference in intelligence is a sensitive topic, long filled with a large number of different opinions. But recent data has indeed shown cognitive (認知的) ability to be higher in some countries than in others. What's more, IQ scores have risen as nations develop—a phenomenon known as the "Flynn effect". Many causes have been put forward for both the intelligence difference and the Flynn effect, including education, income, and even non-agricultural labor. Now, a new study from researchers at the University of New Mexico offers another interesting theory: intelligence may be linked to infectious-disease rates.
[2]The brain, say author Christopher Eppig and his colleagues, is the "most costly organ in the human body". Brainpower consumes almost up to 90 percent of a newborn's energy. It's clear that if something affects energy intake while the brain is growing, the impact could be long and serious. And for vast parts of the globe, the biggest threat to a child's body—and therefore brain—is parasitic (由寄生蟲引起的) infection. These illnesses threaten brain development________________. They can directly attack live tissue, which the body must then try every means to replace. They can invade the digestive pipe and block nutritional intake. They can rob the body's cells for their own reproduction. And then there's the energy channeled (輸送) to the immune system to fight the infection.
[3]Using data on national "disease burdens" (life years lost due to infectious diseases) and average intelligence scores, the authors found they are closely associated. The countries with the lowest average IQ scores have the highest disease burdens without exception. On the contrary, nations with low disease burdens top the IQ list.
[4]If the study holds water, it could be revolutionary for our understanding of the still-confusing variation in national intelligence scores.

Dear Friend,
The recent success of children's books has made the general public aware that there's a huge market out there.
And there's a growing need for new writers trained to create the $3 billion worth of children's books bought each year ... plus stories and articles needed by over 650 publishers of magazines for children and teenagers.
Who are these needed writers? They're ordinary folks like you and me.
But am I good enough?
I was once where you might be now. My thoughts of writing had been pushed down by self-doubt, and I didn't know where to turn for help.
Then, I accepted a free offer from the Institute to test my writing aptitude（潛能）, and it turned out to be the inspiration I needed.
The promise that paid off
The Institute made the same promise to me that they will make to you, if you show basic writing ability:
You will complete at least one manuscript（手稿） suitable to hand in to a publisher by the time you finish our course.
I really didn't expect any publication before I finished the course, but that happened. I sold three stories. And I soon discovered that was not unusual at the Institute.
Since graduation, I have authored 34 nationally published children's books and over 300 stories and articles.
Free test and brochure
We offer a free aptitude test and will send you a copy of our brochure describing our recognized home-study courses on the basis of one-on-one training.
Realize your writing dream today. There's nothing sadder than a dream delayed until it fades forever.
Sincerely,
Kristi Holl, Instructor
Institute of Children's Literature
