People diet to look more attractive. Fish diet to avoid being beaten up, thrown out of their social group, and getting eaten as a result. That is the fascinating conclusion of the latest research into fish behavior by a team of Australian scientists.
The research team have discovered that subordinate fish voluntarily diet to avoid challenging their larger competitors. “In studying gobies we noticed that only the largest two individuals, a male and female, had breeding (繁殖) rights within the group,” explains Marian Wong. “All other group members are nonbreeding females, each being 5-10% smaller than its next largest competitor. We wanted to find out how they maintain this precise size separation.”
The reason for the size difference was easy to see. Once a subordinate fish grows to within 5-10% of the size of its larger competitor, it causes a fight which usually ends in the smaller goby being driven away from the group. More often than not, the evicted fish is then eaten up.
It appeared that the smaller fish were keeping themselves small in order to avoid challenging the boss fish. Whether they did so voluntarily, by restraining how much they ate, was not clear. The research team decided to do an experiment. They tried to fatten up some of the subordinate gobies to see what happened. To their surprise, the gobies simply refused the extra food they were offered, clearly preferring to remain small and avoid fights, over having a feast.
The discovery challenges the traditional scientific view of how boss individuals keep their position in a group. Previously it was thought that large individuals simply used their weight and size to threaten their subordinates and take more of the food for themselves, so keeping their competitors small.
While the habits of gobies may seem a little mysterious, Dr. Wong explains that understanding the relationships between boss and subordinate animals is important to understanding how hierarchical (等級(jí)的) societies remain stable.
The research has proved the fact that voluntary dieting is a habit far from exclusive to humans. “As yet, we lack a complete understanding of how widespread the voluntary reduction of food intake is in nature,” the researchers comment. “Data on human dieting suggests that, while humans generally diet to improve health or increase attractiveness, rarely does it improve long-term health and males regularly prefer females that are fatter than the females’ own ideal.”
When a goby grows to within 5-10% of the size of its larger competitor, it .
A. faces danger B. has breeding rights
C. eats its competitor D. leaves the group itself

China is now sending more college students to study in the United States than any other country. A new report shows a 23 percent increase in the number of Chinese students coming to the U.S.
The latest edition of the annual Institute of International Education(IIE)and another US institute found a 5 percent rise in the number of international university students in the US compared to one year ago. There are now over 157, 000 Chinese students at U.S. colleges and universities.
Aisa accounted for four of the top five countries and regions to take advantage of the US higher education system. “Increased numbers of students from China, particularly at the undergraduate level, largely accounts for the growth this past year,” the report stated. “They really enroll in a full range of US higher education,” said Peggy Blumenthal, senior counselor to the president of IIE, the group that made the report. “20 years ago, students from China only knew of a handful of US insitiutions, but now, they are enrolling in our community colleges, in our small liberal arts institutions, in the research universities. Really spread across the country,” she said.
Chinese mainland was in the number one spot, while India was the number two country of origin. South Korea was third and Canada was number four. China’s Taiwan held the number five spot. Saudi Arabia was in sixth with a 44-percent increase, while Japan was seventh, down 14 percent.
Blumenthal attributes the increase in the number of Chinese students heading to US colleges to limited university places in China, as well as a feeling from students and their parents than they want a “unique” educational experience. China’s family planning policy, says Blumenthal, has also meant that families can concentrated resources on a single child.
The University of California at Los Angeles has one of the largest Asian student populations of any college in the United States.
1.Which ranked the third place sharing US higher education?
A.Saudi Arabia B.South Korea C.Canada D.India
2.Why is the number of Chinese students going to the US increasing?
A.The US colleges are better than those in China.
B.Each family in China has only one child.
C.China lacks enough educational resources.
D.Chinese students can enter varieties of US colleges.
3.Which of the following is right according to Peggy Blumenthal?
A.The number of Chinese students going to the US has increased by 23%.
B.The University of California has contributed to Asian education greatly.
C.Chinese student populations in the US mainly consist of undergraduates.
D.Chinese students know more about US higher education than before.
4.The best title for the passage can be .
A.Chinese College Students Rush to US Schools
B.The Large Number of Chinese Students in the US
C.Chinese Students Make Up Largely Foreign Students in the US
D.Asian Middle School Students in the US Universities

Sparrow is a fast-food chain with 200 restaurants. Some years ago, the group to which Sparrow belonged was taken over by another company. Although Sparrow showed no sign of declining, the chain was generally in an unhealthy state. With more and more fast-food concepts reaching the market, the Sparrow menu had to struggle for attention. And to make matters worse, its new owner had no plans to give it the funds it required.
Sparrow failed to grow for another two years. Until a new CEO, Carl Pearson, decided to build up its market share. He did a survey, which showed that consumers who already used Sparrow restaurants were extremely positive about the chain, while customers of other fast-food chains were unwilling to turn away from them. Sparrow had to develop a new promotional campaign.
Pearson faced a battle over the future of the Sparrow brand. The chain’s owner now favored rebranding Sparrow as Marcy’s restaurants. Pearson resisted, arguing for an advertising campaign designed to convince customers that visits to Sparrow restaurants were fun. Such an attempt to establish a positive relationship between a company and the general public was unusual for that time. Pearson strongly believed that numbers were the key to success, rather than customers’ speeding power. Finally, the owner accepted his idea.
The campaign itself changed the traditional advertising style of the fast-food industry. The TV ads of Sparrow focused on entertainment and featured original songs performed by a variety of stars. Instead of showing the superiority of a specific product, the intention was to put Sparrow in the hearts of potential customers.
Pearson also made other decisions which he believed would contribute to the new Sparrow image. For example, he offered to lower the rent of any restaurants which achieved a certain increase in their turnover (營(yíng)業(yè)額) .
These efforts paid off, and Sparrow soon became one of the most successful fast-food chains in the regions where it operated.
1.Which was one of the problems Sparrow faced before Pearson became CEO?
A.The number of its customers was declining
B.Its customers found the food unhealthy
C.It was in need of financial support
D.Most of its restaurants were closed
2.What does the underlined word “them” in Paragraph 2 refer to?
A.Customers of Sparrow restaurants B.Sparrow restaurants
C.Customers of other fast-food chains D.other fast-food chains
3.For what purpose did Pearson start the advertising campaign?
A.To build a good relationship with the public
B.To stress the unusual tradition of Sparrow
C.To lean about customers’ spending power.
D.To meet the challenge from Marcy’s restaurants.
4.The TV ads of Sparrow ________ .
A.changed people’s views on pop stars
B.a(chǎn)mused the public with original songs
C.focused on the superiority of its products
D.influenced the eating habits of the audience
5.What was Pearson’s achievement as a CEO?
A.He managed to pay off Sparrow’s debts.
B.He made Sparrow much more competitive
C.He helped Sparrow take over a company
D.He improved the welfare of Sparrow employees

Bursting into the classroom from recess(學(xué)生的課間休息), 15 children take their seats and face the woman they know as Ms. Yang.
“What day is it today?”she asks, in Mandarin(普通話的舊稱) Chinese.
“Confucius’ birthday!”the fifth graders shout in Mandarin.
“Why do we celebrate Confucius’ birthday?”
“Because he’s the greatest teacher in the history of China!”exclaims a brown-haired girl. She too is speaking Mandarin.
English is rarely heard in Lisa Yang’s class at the Chinese American International School(CAIS), despite the fact that few students are native speakers of Mandarin.
The United States is actively trying to increase the group of students in“critical languages”such as Mandarin. The students at CAIS are way ahead in such a trend.
Mandarin explosion in America
Founded 25 years ago, this small private school in San Francisco, USA, does what few other American schools do: It produces fully fluent speakers of Mandarin Chinese, by far the most commonly spoken language in the world.
Mandarin Chinese is suddenly hot in American schools. As China becomes the world’s leading economy sometimes this century, schools in the U.S. are scrambling to add Mandarin to their roster of foreign languages or expand Chinese programs already in place.
“It really is almost unprecedented(無(wú)前例的). People are looking at China as a force to be reckoned with…And to ensure that the U.S. has the ability to conduct trade, and to work with the Chinese, certainly having an understanding of Chinese language and culture is an advantage,”said Marty Abbott of the American Council on the Teaching of Foreign Languages(ACTFL)(美國(guó)外語(yǔ)教學(xué)協(xié)會(huì)).
Cultural differences in teaching styles
To develop Chinese-language programs has not been smooth. A shortage of trained teachers has made it difficult for some schools to join the race. When schools do get teachers, they often hire them straight from China, and the teachers usually suffer culture shock when they come to the U.S.
Robert Liu remembers his first two years in an American classroom. It was not an easy adjustment. “In China, students respect their teachers,”he said. Liu found that American students, however, expect an active teaching style. He had to use games to engage them rather than lectures.
To avoid many of the problems with foreign teaching styles, the CAIS has been working with the Chinese government to improve training of teachers who are sent to the U.S.
