Development of a widely accepted chronology for the arrival of humans has been equally difficult, and it was only with the development of optically stimulated luminescence dating that a human presence in Australia was confirmed at 53,000 to 60,000 years ago. Older dates for a human presence in Australia have now been shown to be erroneous .
The importance of Australia as a separate natural laboratory in which to test extinction theories lies in the fact that humans arrived there much earlier than they arrived in the other continental areas (the Americas and northern Eurasia) that experienced substantial megafaunal extinction. What Miller et al. have shown is that the extinction of Genyornis occurred simultaneously across southeastern Australia (indeed probably right across the continent) about 50,000 years ago. This is very close to the presently accepted time of arrival of humans in Australia. It was also a period of modest climate change, well before the dramatic climatic fluctuations of the terminal Pleistocene. The data of Miller et al., therefore, support those who see human hunting rather than climate as causing the extinction of the megafauna.
Genyornis was a ponderous bird, around 80 to 100 kg in weight, about twice as heavy as the living emu and cassowary. It was an inhabitant of Australia?s inland plains and some coastal regions, but its legs were relatively short and thick, suggestion that it was a slower runner than the emu. Proponents of human?caused extinction suggest that it is just such characteristics that made the megafauna vulnerable to human hunting.
A new school of thought has recently established itself in the extinction debate. It advocates the idea that a combination of human impact and climate change was responsible for the extinction of the world?s megafauna. The new Genyornis data also weaken that argument, for the following reason. Fifty thousand years ago, Australia was experiencing mild cooling; 11,000 to 12,000 years ago, the Americas were experiencing rapid warming. These disparate climatic conditions, all coincident with megafaunal extinction, suggest that whatever was happening with climate, it was bad for the big animals. Under these conditions, the hybrid model becomes indistinguishable from the human?caused extinction model for the influence of climate becomes extremely weak, and only the arrival of humans is important in predicting extinction.
1. The last word “megafauna” in Paragraph 2 most probably means
A birds. B plants.
C big animals. D small animals.
2. Genyornis was vulnerable to human hunting because it was
A a delicacy. B very weak.
C very small in size. D clumsy.
3. How many models have been put forward for the extinction of Genyoris?
A One. B Two.
C Three. D Four.
4. That Australia experienced mild cooling and the Americas rapid warming suggests that
A the climatic conditions were unfit for Genyornis to live.
B Genyornis were highly adaptable to different climatic conditions.
C The two climatic conditions were both bad for Genyornis.
D The climatic conditions had nothing to do with the extinction of Genyoris.
5. The selection is mainly about
A the debate over the time of the human presence in Australia.
B the relationship between the human presence and magafaunal extinction.
C the relationship between human activities and climatic changes.
D the debate over factors causing megafaunal extinction.

澳洲古代巨鳥(niǎo)滅絕探因
要?jiǎng)?chuàng)建人類是何時(shí)到來(lái)的、且為人們所廣為接受的年代表同樣也是困難的。并且只有在光學(xué)模擬發(fā)光測(cè)定年代的方法發(fā)展起來(lái)后,人們才確定53,000年到60,000年前澳洲有了人類,現(xiàn)在已證明更久遠(yuǎn)的年代是錯(cuò)誤的。
之所以把澳洲稱為試驗(yàn)種族滅絕理論的天然實(shí)驗(yàn)室,其重要性在于(lie in):人類到達(dá)這兒的年代要遠(yuǎn)遠(yuǎn)先于到達(dá)經(jīng)歷過(guò)巨型動(dòng)物滅亡的其他大陸(如歐洲和歐亞大陸北部)的年代。Miller等人向我們說(shuō)明,“巨鳥(niǎo)”于50,000年前在澳洲南部同時(shí)滅絕,這和人們普遍接受的人類到達(dá)澳洲大陸的時(shí)間相當(dāng)接近。這也是氣候溫和的時(shí)期,隨后很久才發(fā)生了更新世晚期滅絕性的氣候劇變。Miller的資料支撐了認(rèn)為人類捕獵而非氣候變化是巨獸滅絕的原因的觀點(diǎn)。
“巨鳥(niǎo)”是遠(yuǎn)古時(shí)期一種巨型鳥(niǎo)類,重約80到100公斤,是鴯鹋和食火雞的兩倍重。它是澳洲內(nèi)陸和沿海地區(qū)的動(dòng)物,但它的腿相對(duì)短而粗,證明它不如鴯鹋跑得快。堅(jiān)持人類導(dǎo)致這種鳥(niǎo)滅絕的人說(shuō),它們的這種特性使它們很容易受到(be vulnerable to ...)捕殺。
在這一“滅絕爭(zhēng)論”中,新的學(xué)派又建立了。他們贊成人類及氣候因素結(jié)合導(dǎo)致(be responsible for ...)了世界范圍巨型動(dòng)物的滅絕的觀點(diǎn)。新的巨鳥(niǎo)資料也削弱了這種爭(zhēng)論,原因如下:50,000年前,澳洲氣候逐漸變冷;11,000到12,000年前,美洲氣溫迅速上升。這些完全相異的氣候條件正好與巨鳥(niǎo)滅絕時(shí)期相吻合(be coincident with)。這說(shuō)明,無(wú)論氣候怎樣變化,巨型動(dòng)物還是難逃厄運(yùn)。在這種情況下(under these conditions),這種結(jié)合兩種說(shuō)法的觀點(diǎn)就變得與人類導(dǎo)致其滅絕的觀點(diǎn)難以區(qū)別了。因?yàn)樵谒麄兛?/span>來(lái),氣候影響是那么微弱,只有人類的到來(lái)才預(yù)示了巨型動(dòng)物的滅絕。

A new study has found evidence of aggressive (攻擊性的) behavior in children who drink four or more servings of soft drinks every day. Information for the study came from the mothers of 3,000 5-year-olds. Researchers asked the women to keep a record of how many servings of soft drinks their children drank over a two-month period. They were also asked to complete a checklist of their children’s behavior.
The researchers have found that 43 percent of the children drink at least one daily serving of soda, and 4 percent of the youngsters have even four or more sodas to drink every day.
Shakira Suglia, a famous expert, says they’ve found that children who drink the most soda are more than twice as likely as those who drink no soda to show signs of aggression.
“For the children who consume four or more soft drinks per day, we see more withdrawn behaviors, which make them hard to get along well with others.”
The aggressive behaviors include destroying possessions belonging to others, taking part in fights and physically attacking people.
The researchers have determined the link after considering factors like the child’s age and sex. They have also considered other possible influence, such as whether the boys and girls are eating sweets or giving fruit drinks on a normal day. In addition, the researchers have examined parenting styles and other social conditions that may be taking place in the home.
Researches are trying to find why young children who drink a lot of soda have behavior problems. An ingredient often found in soft drinks is caffeine, which helps to make people feel energetic. Doctor Suglia suggests that caffeine could cause the 5-year-olds to be more aggressive. Earlier studies of adults have found the highest sugar levels in those who carry weapons (武器) and show signs of negative social behavior.
1.What section of a newspaper is the passage probably taken from?
A. Scientific TechnologyB. Science Fictions
C. Social NewsD. Health Report
2.The underlined word “withdrawn” in paragraph 4 can probably be replaced by the word ______.
A. backwardB. unsocialC. generousD. friendly
3.Researchers studied the following aspects of the children except ______.
A. ageB. sexC. gamesD. parents
4.According to the research, which of the following is right?
A. Mothers were asked to keep a record of how many servings of soft drinks their children drank over a three-month period.
B. 4 percent of the youngsters have even four or fewer sodas to drink every day.
C. Children who drink no soda show fewer aggressive behaviors.
D. Children with the highest sugar levels tend to carry weapons and show signs of negative social behavior.
5.After a further study on ingredients in soda, Shakira Suglia implies that the direct cause of the aggressive behaviors may be ______.
A. soft drinks B. attention problems
C. caffeine D. social conditions

Usually, when your teacher asks a question, there is only one correct answer. But there is one question that has millions of current answers. That question is “What’s your name?” Everyone gives a different answer, but everyone is correct.
Have you ever wondered about people’s names? Where do they come from? What do they mean?
People’s first names, or given names, are chosen by their parents. Sometimes the name of a grandparent or other member of the family is used. Some parents choose the name of a well-known person. A boy could be named George Washington Smith; a girl could be named Helen Keller Jones.
Some people give their children names that mean good things. Clara means “bright”; Beatrice means “one who gives happiness”; Donald means “world ruler”; Leonard means “as brave as a lion”.
The earliest last names, or surnames, were taken from place names. A family with the name Brook or Brooks probably lived near brook(小溪);someone who was called Longstreet probably lived on a long, paved road. The Greenwood family lived in or near a leafy forest.
Other early surnames came from people’s occupations. The most common occupational name is Smith, which means a person who makes things with iron or other metals. In the past, smiths were very important workers in every town and village. Some other occupational names are: Carter — a person who owned or drove a cart; Potter —a person who made pots and pans.
The ancestors of the Baker family probably baked bread for their neighbors in their native village. The Carpenter’s great-great-great-grandfather probably built houses and furniture.
Sometimes people were known for the color of their hair or skin, or their size, or their special abilities. When there were two men who were named John in the same village, the John with the gray hair probably became John Gray. Or the John was very tall could call himself John Tallman. John Fish was probably an excellent swimmer and John Lightfoot was probably a fast runner or a good dancer.
Some family names were made by adding something to the father’s name. English-speaking people added –s or –son. The Johnsons are descendants of John; the Roberts family’s ancestor was Robert. Irish and Scottish people added Mac or Mc or O. Perhaps all of the MacDonnells and the MacDonnells and the O’Donnells are descendants of the same Donnell.
1. Which of the following aspects do the surnames in the passage NOT cover?
A. Places where people lived. B. People’s characters.
C. Talents that people possessed. D. People’s occupations.
2. According to the passage, the ancestors of the Potter family most probably _______.
A. owned or drove a cart B. made things with metals
C. made kitchen tools or contains D. built houses and furniture
3.Suppose and English couple whose ancestors lived near a leafy forest wanted their new-born son to become a world leader, the baby might be named _______.
A. Beatrice Smith B. Leonard Carter
C. George Longstreet D. Donald Greenwood
4. The underlined word “descendants” in the last paragraph means a person’s _____
A. later generations B. friends and relatives
C. colleagues and partners D. later sponsors

A couple of years ago, before a trip to China, Nicole Davis and her US women’s volleyball teammates were warned about the prominence (顯著、突出) of coach “Jenny” Lang Ping in her native country.
“I was pushed over by Chinese journalists while I was just trying to put my luggage on the bus,” said Davis.
Known as the “Iron Hammer” for her punishing spikes(扣球),Lang made it possible for China to dominate in the sport in the early 1980s. She was a key player on China’s 1984 Olympic gold medal winning team.
When the US team arrived for the Olympics, Lang, 48, who is from Beijing, had to take a different route to avoid a crowd of reporters and fans.
Then came the greatest moment to Lang:While the US team was playing in a packed gym, at least 8,000 Chinese fans unfurled an American flag.
“That really says it all,” Davis said. “They look at her as an icon(偶像).I’m sure it’s hard for them to see her coaching another country, but they love her so 七彩教育網(wǎng)ly that her success is their success.”
The loyalty of the Chinese fans was tested on Friday, when China lost a match to the US.
“It’s a pity that China lost the match, but I’m still glad that Lang Ping’s team won, since she is the pride of China’s volleyball,” said Liu Chengli, a spectator. “We also cheered for
Lang’s victory.”
Lang said she just tried to stay professional when the two teams meet. “It doesn’t matter if we play China or any other team. It’s the same.” Lang said.
Davis said she and her teammates could not have imagined the passion for volleyball among Chinese because the sport was lack of popularity in the US. The reception from Chinese fans has touched the US players, said US volleyball player Lindsey Berg.
“It’s such an honor to be here and play for our coach here in China,” she said. “The amount of support that the Chinese give to her and us has been tremendous. The whole event has been unbelievable.”
1. What’s the passage mainly about?
A.Staying professional.B.Cheering for the Iron Hammer.
C.A match between China and the US.D.Lang Ping’s career as a coach.

A.was afraid to be questioned about her strategy
B.didn’t want to be paid much attention to
C.disliked to be with her fans
D.didn’t want to disturb public order
3. What does the underlined word “unfurled” exactly mean?
A.destroyed completelyB.tore into pieces
C.spread out to the windD.rolled up
4. What does Lang Ping mean by saying “It doesn’t matter if we play China or any other team.”?
A.American Volleyball Team will beat any team.
B.Chinese Volleyball Team is the same as other teams.
C.She just tried to stay professional.
D.The results of each match will be the same.
5. What impressed the US team players most?
A.The tolerance of Chinese people.
B.The popularity of volleyball in China.
C.Lang Ping’s coaching skills.

A few common misconceptions. Beauty is only skin-deep. One' s physical assets and liabilities don' t count all that much in a managerial career. A woman should always try to look her best.
Over the last 30 years, social scientists have conducted more than 1,000 studies of how we react to beautiful and not- so-beautiful people. The virtually unanimous conclusion: Looks do matter, more than most of us realize. The data suggest, for example, the physically attractive individuals are more likely to be treated well by their parents, sought out as friends, and pursued romantically. With the possible exception of women seeking managerial jobs they are also more likely to be hired, paid well, and promoted.
Un-American, you say, unfair and extremely unbelievable? Once again, the scientists have caught us mouthing pieties (虔誠(chéng)) while acting just the contrary. Their typical experiment works something like this. They give each member of a group--college students, perhaps, or teachers or corporate personnel managers a piece of paper relating an individual' s accomplishments. Attached to the paper is a photograph. While the papers all say exactly the same thing the pictures are different. Some show a strikingly attractive person, some an average-looking character, and some an unusually unattractive human being. Group members are asked to rate the individual on certain attributes, anything from personal warmth to the likelihood that he or she will be promoted.
Almost invariably, the better looking the person in the picture, the higher the person is rated. In the phrase, borrowed from Sappho, that the social scientists use to sum up the common perception, what is beautiful is good.
In business, however, good looks cut both ways for women, and deeper than for men. A Utah State University professor, who is an authority on the subject, explains: In terms of their careers, the impact of physical attractiveness on males is only modest. But its potential impact on females can be tremendous, making it easier, for example, for the more attractive to get jobs where they are in the public eye. on another note, though, there is enough literature now for us to conclude that attractive women who aspire (追求) to managerial positions do not get on as well as who may be less attractive.
1. In "Beauty is only skin-deep", "skin-deep" can be replaced by______.
A. decorating B. superficial C. expressive D. demanding
2. "One's physical assets and liabilities don' t count all that much in a managerial career."(paral) can be interpretated as______.
A. whether or not one looks good or bad, it doesn' t affect much one' s managerial career
B. in one' s managerial career, he may deal with cases like assets and liabilities
C. in one' s managerial career, he may rarely deal with cases like assets and liabilities
D. whether or not one looks good or bad, it may affect much one' s managerial career
3. The result of research carried out by social scientists show that______.
A. people do not realize the importance of looking one' s best
B. women in pursuit of managerial jobs are not likely to be paid well
C. good -looking women aspire to managerial positions
D. attractive people generally have an advantage over those who are not
4. "Good looks cut both ways for women" (Para.5) means that______.
A. attractive women have tremendous potential impact on public job
B. good-looking women always get the best of everything
C. being attractive is not always an advantage for women
D. attractive women do not do as well as unattractive women in managerial positions
5. It can be inferred from the passage that in the business world______.
A. handsome men are not affected as much by their looks as attractive women are
B. physically attractive women who are in the public eye usually do quite well
C. physically attractive men and women who are in the public eye usually get along quite well
D. good looks are important for women as they are for men

His ignorance was as remarkable as his knowledge. Of contemporary literature, philosophy and politics he appeared to know next to nothing. Upon my quoting Thomas Carlyle, he inquired in the naivest way who he might be and what he had done. My surprise reached a climax, however, when I found incidentally that he was ignorant of the Copernican Theory and of the composition of the Solar system.
“You appear to be astonished, ” Holmes said, smiling at my expression. “Now that I do know it I shall do my best to forget it. You see, I consider that a man’s brain originally is like a little empty attic, and you have to stock it with such furniture as you choose: A fool takes in all the lumber of every sort that he comes across, so that the knowledge which might be useful to him gets crowded out, or at best jumbled up with a lot of other things, so that he has difficulty in laying his hand upon it. It is a mistake to think that the little room has elastic walls and can distend to any extent. Depend upon it, there comes a time when for every addition of knowledge you forget something that you know before. It is of the highest importance, therefore, not to have useless facts elbowing out the useful ones.”
“But the Solar System! ” I protested.
“What the deuce is it to me?” he interrupted impatiently.
One morning, I picked up a magazine from the table and attempted to while away the time with it, while my companion munched silently at his toast. One of the articles had a pencil mark at the heading, and I naturally began to run my eye through it.
Its somewhat ambitious title was “The Book of Life, ” and it attempted to show how much an observant man might learn by an accurate and systematic examination of all that came in his way. It struck me as being a remarkable mixture of shrewdness and of absurdity. The reasoning was close and intense, but the deduction appeared to me to be far-fetched and exaggerated. The writer claimed by a momentary expression, a twitch of a muscle or a glance of an eye, to fathom a man’s inmost thought. Deceit, according to him, was impossibility in the case of one trained to observation and analysis. His conclusions were as infallible as so many propositions of Euclid. So startling would his results appear to the uninitiated that until they learned the processes by which he had arrived at them they might well consider him as a necromancer.
“From a drop of water, ”said the writer, “a logician could infer the possibility of an Atlantic. So all life is a great chain, the nature of which is known whenever we are shown a single link of it. Like all other arts, the science of Deduction and Analysis is one which can be acquired by long and patient study, nor is life long enough to allow any mortal to attain the highest possible perfection in it. ”
This smartly written piece of theory I could not accept until a succession of evidences justified it.
1. What is the author’s attitude toward Holmes?
[A]Praising.
[B]Critical.
[C]Ironical.
[D]Distaste.
2. What way did the author take to stick out Holmes’ uniqueness?
[A]By deduction.
[B]By explanation.
[C]By contrast.
[D]By analysis.
3. What was the Holmes’ idea about knowledge-learning?
[A]Learning what every body learned.
[B]Learning what was useful to you.
[C]Learning whatever you came across.
[D]Learning what was different to you.
4. What did the article mentioned in the passage talk about?
[A]One may master the way of reasoning through observation.
[B]One may become rather critical through observation and analysis.
[C]One may become rather sharp through observation and analysis.
[D]One may become practical through observation and analysis.
