1 . Cloud computing will be in use by about 80 percent of about 600 companies. The trend suggests that data management and storage are moving to cloud computing sellers on a large scale.

Touting(兜售)cloud computing as a way to get rid of the costs of buying and maintain in on-site information-technology equipment, sellers offer it in the form of Software AsA. Service(SAAS), a delivery model in which software applications are delivered to customers over a web-based network. SAAS can serve the needs of entire companies through huge, web-based platforms. As cloud computing rapidly bccomes the delivery channel for software developers of all shapes and sizes to get their products to market, offering applications in a cloud is now the rule not the exception. A. relatively small number of sellers are able to offer SAAS to big companies that want company-wide cloud computing, and only the sellers need apply. Although market-share data are hard to come by, the list of company’s large enough to offer cloud-computing on this scale is short: Microsoft, Amazon, Google, Salesforce, Rackspace and not many others.

The concentration of data and virtual (虚拟)computing in the hands of relatively few sellers raises an important risk for their customers if the Internet-based systems of any one seller are hacked, the result could be security problems across entire industries in which their customers do

Can this small group of cloud-computing sellers effectively respond to the needs of their customers to quickly fix such a problem and, most importantly, cut off the damage to these companies' own customers? Don't think such things can't happen. If hackers can penetrate the Department of Defense, the risk that they will penetrate Microsoft or google cannot be ruled out Compromise of just one of these sellers---even one with a modest market share---possibly could shut down, at least temporarily, a sizable part of the U. S. economy.

2 . I never knew much about my mother's father, John leon La Walla. He moved to the city of Melbourne, Australia, in the 1920s, married, and started to raise a family, but died in World War Two. All we had was one framed photo of him dressed in his army uniform.

For some reason, my grandfather had not kept in touch with any of his relatives, although my mother did recall some family names. It wasn't till 1963 that she finally saw her father's grave, in the Albury War Cemetery in New South Wales. I fiercely wanted to know more about this man. Who were his parents？Who were his brothers and sisters？Were any of them still alive and, if so, where were they now？Did they ever wonder what become of our John Leon？

With the advent（到来）of the Internet, I started searching in earnest in the late 1990s. From my grandfather's records in the army, I learned he'd listed his birthplace as Hertfordshire England." I think his surname must have been a false name," my father said. This made me upset but I put it aside, concentrating instead on my father's line. I joined a genealogy（系谱学）website and was soon discovering some of my ancestors from distant relatives. I wrote, “I just wish I could find out about my mother's father now," and told them of my search.

In late 2012, I heard from a very distant relation on my father's side called Julie, from New Zealand. As a genealogist herself, she'd taken pity on me and spent several weeks on research. It was a bombshell when she said she may have found my grandfather's family.

She'd searched English census（人口普查） records and found the surname Waller. The dates and first names matched right down to a brother who'd died on the Western Front. Julie had overcome the false name, traced a whole tree and put me in touch with current﹣day relatives.

"Consider it an early Christmas present," she said. "Julie had done all this very careful research for a stranger. I will be ever grateful."

3 . Color is a daily mystery．ROY G B.IV deals with lots of big﹣picture color questions explaining why hams are often red and why NYC taxis are yellow．Today's question：why are Jeans blue？

First，why"jeans"？Jeans twin names﹣denim and jeans﹣come from the two European ports that supplied two similar fabrics（织物）during the Middle A.ges． Gene fustian was a cotton﹣linen﹣wool blend shipped from genoa．a silk ﹣wool blend called serge de nimes shortened to de nimes or denim， was shipped out of France．B.oth fabrics gradually changed into similar cotton only blends by the 19th century． according to an article titled a short history of denim y historian Lynn Downey． B.oth were used to make men's clothing，valued especially for [their] properly of durability（耐久性） even after many washings"．

In 1873 Levi Strauss teamed up with Jacob Davis to produce jeans，they sold like hotcakes to Gold Rush miners secking a durable uniform for fortune﹣seeking Jeans rapidly came to stand for the character of the A.merican West﹣﹣rank， energetic， rebellions，and capitalistic．

While gold rush miners probably didnt care about how denim looked， they cared a lot about durability，comfort and fit，at the beginning，Straus offered his waist overalls"in two varieties brown cotton"duck"or canvas，and blue denim﹣﹣but by 1911 they'd stopped using cotton duck entirely．As historian Downey explains "once someone had worn a pair of denim pants experiencing its strength． and how the denim became more comfortable with every washing he never wanted to wear duck again； because with cotton duck，you always feel like you re wearing a tent．"

So why are jeans blue？The answer has to do with dye．Unlike most natural dyes that， when heated，penetrate cloth fibers directly indigo（靛蓝）sticks to the cloth's threads．With each washing some of these dye molecules are stripped away，taking bits of the threads with them．The process softens rough fabrics and individualizes the color．This extreme customization made every pair a second skin．

1. How does the author start talking about jeans？

A．From the quality of the fabrics．

B．From a famous historian．

C．From their hometowns．

D．From their names．

2. Which of the following helped establish the popularity of jeans in 1873？

A．Hot cakes．

B．A. durable uniform．

C．A.merican character．

D．Gold rush．

3. What can we infer about indigo？

A．It cannot be heated．

B．It can be machine washed．

C．It doesn't stay for a long time．

D．It goes into the cloths fibers directly．

4. By saying"made every pair a second skin" in the last paragraph, the author most probably means____________．

A．the pants were made of skin．

B．the pants fitted people well．

C．the dyes were quite natural．

D．the threads became softer and softer．

4 . Julie boergers, Ph．D a sleep expert from the Bradley Hasbro Children's Research Center, recently led a study connecting later school start times to improved sleep and mood in teens．

"Sleep deprivation is common among teenagers, with potentially serious impacts on mental and physical health, safety and learning.Early high school start times contribute to this problem，"said Boergers."In this study, we looked at whether a delay in school start time would change students' sleep patterns, sleepiness, mood and caffeine(咖啡因)use."

Beorgers' team conducted the School Sleep Habits survey among boarding students attending an independent high school both before and after their school start time was experimentally delayed from 8 to 8:25 a.m.during the winter term.The delay in school start time led to a significant increase (29 minutes)in sleep duration on school nights, with the percentage of students receiving eight or more hours of sleep on a school night jumping from 18 to 44 percent The research found that younger students and those sleeping less at the start of the study were most likely to benefit from the timetable change.Daytime sleepiness, low mood and caffeine use were all significantly reduced after the delay in school start time.The later school start time had no effect on the number of hours students spent doing homework, playing sports or taking part in activities outside class. And once the earlier start time changed back during the spring term, teens reverted(恢复)back to their original levels.

Beorgers said that these findings are important for public policy."The result of this study add to a growing body of research showing important health benefits of later school start times for adolescents, " she said, " and we have students who are more alert(机敏的), happier, better prepared to learn, and aren't dependent on caffeine and energy drinks just to stay awake in class."

5 . As more and more people speak the global languages of English, Chinese, Spanish, and Arabic, other languages are rapidly disappearing. In fact, half of the 6,000-7,000 languages spoken around the world today will likely die out by the next century, according to the United Nations Educational, Scientific, and Cultural Organization (UNESCO).
In an effort to prevent language loss, scholars from a number of organizations- UNESCO and National Geographic among them –have for many years been documenting dying languages and the cultures they reflect.
Mark Turin, a scientist at the Macmillan Center, Yale University, who specializes in the languages and oral traditions of the Himalayas, is following that tradition. His recently published book, A Grammar of Thangmi with an Ethnolinguistic Introduction to the Speakers and Their Culture, grows out of his experience living, looking and raising a family in a village in Nepal.
Documenting the Tangmi language and culture is just a starting point for Turin, who seeks to include other languages and oral traditions across the Himalayans reaches of India, Nepal, Bhutan, and China. But he is not content to simply record these voices before they disappear without record.
At the University of Cambridge Turin discovered a wealth of important materials- including photographs, films, tap recordings, and field notes- which had remained unstudied and were badly in need of care and protection.
Now, through the two organizations that he has founded-the Digital Himalaya Project and the World Oral Literature Project- Turin has started a campaign to make such documents, found in libraries and stores around the world, available not just to scholars but to the youngers.
Generations of communities from whom the materials were originally collected.Thanks to digital technology and the widely available Internet. Turin notes, the endangered languages can be saved and reconnected with speech communities.

6 . When I was six, Dad brought home a dog one day, who was called “Brownie”. My brothers and I all loved Brownie and did different things with her. One of us would walk her, another would feed her, then there were baths, playing catch and many other games. Brownie, in return, loved each and every one of us. One thing that most touched my heart was that she would go to whoever was sick and just be with them. We always felt better when she was around.
One day, as I was getting her food, she chewed up(咬破)one of Dad’s shoes, which had to be thrown away in the end. I knew Dad would be mad and I had to let her know what she did was wrong. When I looked at her and said, “Bad girl,” she looked down at the ground and then went and hid. I saw a tear in her eyes.
Brownie turned out to be more than just our family pet. She went everywhere with us. People would stop and ask if they could pat her. Of course she’d let anyone pat her. She was just the most lovable dog. There were many times when we’d be out walking and a small child would come over and pull on her hair. she never barked(吠) or tried to get away. Funny thing is that she would smile. This frightened people because they thought she was showing her teeth. Far from the truth, she loved everyone.

7 . In the mid-1990s, Tom Bissell taught English as a volunteer in Uzbekistan. He left after seven months, physically broken and having lost his mind. A few years later, still attracted to the country, he returned to Uzbekistan to write an article about the disappearance of the Aral Sea.

His visit, however, ended up involving a lot more than that. Hence this book, Chasing the Sea: Lost Among the Ghosts of Empire in Central Asia, which talks about a road trip from Tashkent to Karakalpakstan, where millions of lives have been destroyed by the slow drying up of the sea. It is the story of an American travelling to a strange land, and of the people he meets on his way: Rustam, his translator, a lovely 24-year-old who picked up his colorful English in California, Oleg and Natasha, his hosts in Tashkent, and a string of foreign aid workers.

This is a quick look at life in Uzbekistan, made of friendliness and warmth, but also its darker side of society. In Samarkand, Mr Bissell admires the architectural wonders, while on his way to Bukhara he gets a taste of police methods when suspected of drug dealing. In Ferghana, he attends a mountain funeral(葬礼)followed by a strange drinking party. And in Karakalpakstan, he is saddened by the dust storms, diseases and fishing boats stuck miles from the sea.

Mr Bissell skillfully organizes historical insights and cultural references, making his tale a well-rounded picture of Uzbekistan, seen from Western eyes. His judgment and references are decidedly American, as well as his delicate stomach. As the author explains, this is neither a travel nor a history book, or even a piece of reportage. Whatever it is, the result is a fine and vivid description of the purest of Central Asian traditions.

1. What made Mr Bissell return to Uzbekistan?

A．His friends' invitation.	B．His interest in the country.
C．His love for teaching.	D．His desire to regain health.

2. What does the underlined word “that” in paragraph 2 refer to?

B．Eventful.

C．Pleasant.

D．Dangerous.

4. What is the purpose of this text?

A．To introduce a book.	B．To explain a cultural phenomenon.
C．To remember a writer.	D．To recommend a travel destination.

8 . According to a recent study in the Journal of Consumer Research, both the size and consumption habits of our eating companions can influence our food intake. And contrary to existing research that says you should avoid eating with heavier people who order large portions(份), it's the beanpoles with big appetites you really need to avoid.

To test the effect of social influence on eating habits, the researchers conducted two experiments. In the first, 95 undergraduate women were individually invited into a lab to ostensibly(表面上)participate in a study about movie viewership. Before the film began, each woman was asked to help herself to a snack. An actor hired by the researchers grabbed her food first. In her natural state, the actor weighed 105 pounds. But in half the cases she wore a specially designed fat suit which increased her weight to 180 pounds.

Both the fat and thin versions of the actor took a large amount of food. The participants followed suit, taking more food than they normally would have. However, they took significantly more when the actor was thin.

For the second test, in one case the thin actor took two pieces of candy from the snack bowls. In the other case, she took 30 pieces. The results were similar to the first test: the participants followed suit but took significantly more candy when the thin actor took 30 pieces.

The tests show that the social environment is extremely influential when we're making decisions. If this fellow participant is going to eat more, so will I. Call it the “I’ll have what she's having” effect. However, we'll adjust the influence. If an overweight person is having a large portion, I'll hold back a bit because I see the results of his eating habits. But if a thin person eats a lot, I'll follow suit. If he can eat much and keep slim, why can't I?

1. What is the recent study mainly about?

A．Food safety.	B．Movie viewership.
C．Consumer demand.	D．Eating behavior.

2. What does the underlined word “beanpoles” in paragraph 1 refer to?

A．Big eaters.	B．Overweight persons.
C．Picky eaters.	D．Tall thin persons.

3. Why did the researchers hire the actor?

A．To see how she would affect the participants.

B．To test if the participants could recognize her.

C．To find out what she would do in the two tests.

D．To study why she could keep her weight down.

4. On what basis do we “adjust the influence” according to the last paragraph?

A．How hungry we are.	B．How slim we want to be.
C．How we perceive others.	D．How we feel about the food.

9 . Jenifer Mauer has needed more willpower than the typical college student to pursue her goal of earning a nursing degree. That willpower bore fruit when Jennifer graduated from University of Wisconsin-Eau Claire and became the first in her large family to earn a bachelor's degree.

Mauer, of Edgar, Wisconsin, grew up on a farm in a family of 10 children. Her dad worked at a job away from the farm, and her mother ran the farm with the kids. After high school, Jennifer attended a local technical college, working to pay her tuition(学费), because there was no extra money set aside for a college education. After graduation, she worked to help her sisters and brothers pay for their schooling.

Jennifer now is married and has three children of her own. She decided to go back to college to advance her career and to be able to better support her family while doing something she loves: nursing. She chose the UW-Eau Claire program at Ministry Saint Joseph's Hospital in Marshfield because she was able to pursue her four-year degree close to home. She could drive to class and be home in the evening to help with her kids. Jenifer received great support from her family as she worked to earn her degree: Her husband worked two jobs to cover the bills, and her 68-year-old mother helped take care of the children at times.

Through it all, she remained in good academic standing and graduated with honors. Jennifer sacrificed(牺牲)to achieve her goal, giving up many nights with her kids and missing important events to study. ''Some nights my heart was breaking to have to pick between my kids and studying for exams or papers,'' she says. However, her children have learned an important lesson witnessing their mother earn her degree. Jennifer is a first-generation graduate and an inspiration to her family-and that's pretty powerful.

A．Time is money.	B．Love breaks down barriers.
C．Hard work pays off.	D．Education is the key to success.

10 . We are the products of evolution, and not just evolution that occurred billions of years ago. As scientists look deeper into our genes (基因), they are finding examples of human evolution in just the past few thousand years. People in Ethiopian highlands have adapted to living at high altitudes. Cattle -raising people in East Africa and northern Europe have gained a mutation (突变) that helps them digest milk as adults.

On Thursday in an article published in Cell, a team of researchers reported a new kind of adaptation - not to air or to food, but to the ocean. A group of sea-dwelling people in Southeast Asia have evolved into better divers. The Bajau, as these people are known, number in the hundreds of thousands in Indonesia, Malaysia and the Philippines. They have traditionally lived on houseboats; in recent times, they’ve also built houses on stilts (支柱) in coastal waters. “They are simply a stranger to the land,” said Redney C. Jubilado, a University of Hawaii researcher who studies the Bajau.

Dr. Jubilado first met the Bajau while growing up on Samal Island in the Philippines. They made a living as divers, spearfishing or harvesting shellfish. “We were so amazed that they could stay underwater much longer than us local islanders,” Dr. Jubilado said. “I could see them actually walking under the sea.”

In2015, Melissa Ilardo, then a graduate student in genetics at the University of Copenhagen, heard about the Bajau. She wondered if centuries of diving could have led to the evolution of physical characteristics that made the task easier for them. “it seemed like the perfect chance for natural selection to act on a population,” said Dr. Ilardo. She also said there were likely a number of other genes that help the Bajau dive.

1. What does the author want to tell us by the examples in paragraph 1?

A．Environmental adaptation of cattle raisers.	B．New knowledge of human evolution.
C．Recent findings of human origin.	D．Significance of food selection.

C．They could stay long underwater.	D．They lived on both land and water.

4. What can be a suitable title for the text?

A．Bodies Remodeled for a Life at Sea	B．Highlanders’ Survival Skills
C．Basic Methods of Genetic Research	D．The World’s Best Divers
