Technological changes brought dramatic new options to Americans living in the 1990s. During this decade new forms of entertainment, commerce, research, andcommunication became commonplace in the U.S. The driving force behind much ofthis change was a(n) 26 popularly known as the Internet.

The Internet was developed during the 1970s by the Department of Defense. In the caseof an attack, military advisers suggested the 27 of being able to operate one computerfrom another terminal. In the early days, the Internet was used mainly by scientists tocommunicate with other scientists. The Internet 28 under government control until1984.

One early problem faced by Internet users was speed. Phone lines could only transmitinformation at a 29 rate. The development of fiber-optic (光纤) cables allowed for billionsof bits of information to be received every minute. Companies like Intel developed fastermicroprocessors, so personal computers could process the 30 signals at a more rapidrate.

In the early 1990s, the World Wide Web was developed, in large part, for 31 purposes.Corporations created home pages where they could place text and graphics tosell products. Soon airline tickets, hotel 32 , and even cars and homes could bepurchased online. Universities 33 research data on the Internet, so students could find 34 information without leaving their dormitories. Companies soon discovered that workcould be done at home and 35 online, so a whole new class of telecommuters began toearn a living from home offices unshaven and wearing pajamas (睡衣).

A) advantage B) commercial C) conservation D) equipped E) incoming F) innovationG) limited H) local I) maintained J) occupations K) posted L) remained M) reservationsN) submitted O) valuable

Section B

Directions: In this section, you are going to read a passage with ten statementsattached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose aparagraph more than once. Each paragraph is marked with a letter. Answer the questionsby marking the corresponding letter on Answer Sheet 2.

The Health Benefits of Knitting

A) About 15 years ago, I was invited to join a knitting group. I agreed to give it a try.

B) My mother had taught me to knit at 15, and I knitted in class throughout college andfor a few years thereafter. Then decades passed without my touching a knitting needle. But within two Mondays in the group, I was hooked, not only on knitting but also oncrocheting (钩织), and I was on my way to becoming a highly productive crafter.

C) I've made countless baby blankets, sweaters, scarves, hats, caps for newborns. I takea knitting project with me everywhere, especially when I have to sit still and listen. As Idiscovered in college, when my hands are busy, my mind stays focused on the here andnow.

D) It seems, too, that I'm part of a national renewal of interest in needle and otherhandicrafts (手工艺). The Craft Yarn Council reports that a third of women ages 25-35 now knit or crochet. Even men and schoolchildren are swelling the ranks, among themmy friend's three small grandsons. Last April, the council created a "Stitch Away Stress" campaign in honor of National Stress Awareness Month. Dr. Herbert Benson, a pioneerin mind/body medicine and author of The Relaxation Response, says that the repetitiveaction of needlework can induce a relaxed state like that associated with meditation(沉思) and yoga. Once you get beyond the initial learning curve, knitting and crochetingcan lower heart rate and blood pressure.

E) But unlike meditation, craft activities result in tangible and often useful productsthat can enhance self-esteem. I keep photos of my singular accomplishments on mycellphone to boost my spirits when needed.

F) Since the 1990s, the council has surveyed hundreds of thousands of knitters andcrocheters, who routinely list stress relief and creative fulfillment as the activities'main benefits. Among them is the father of a prematurely born daughter who reportedthat during the baby's five weeks in the intensive care unit, "learning how to knit infanthats gave me a sense of purpose during a time that I felt very helpless. It's a hobbythat I've stuck with, and it continues to help me cope with stress at work, provide asense of order in hectic (忙乱的) days, and allow my brain time to solve problems."

G) A recent email from the yarn (纺纱) company Red Heart titled "Health Benefits ofCrocheting and Knitting" prompted me to explore what else might be known about thehealth value of activities like knitting. My research revealed that the rewards go wellbeyond replacing stress and anxiety with the satisfaction of creation.

H) For example, Karen Hayes, a life coach in Toronto, conducts knitting therapyprograms, including Knit to Quit to help smokers give up the habit, and Knit to Heal forpeople coping with health crises, like a cancer diagnosis or serious illness of a familymember. Schools and prisons with craft programs report that they have a calmingeffect and enhance social skills. And having to follow instructions on complex craftprojects can improve children's math skills.

I) Some people find that craftwork helps them control their weight. Just as it'schallenging to smoke while knitting, when hands are holding needles and hooks, there'sless snacking and mindless eating out of boredom.

J) I've found that my handiwork with yarn has helped my arthritic (患关节炎的) fingersremain more dexterous (灵巧的) as I age. A woman encouraged to try knitting andcrocheting after developing an autoimmune disease that caused a lot of hand painreported on the Craft Yarn Council site that her hands are now less stiff and painful.

K) A 2009 University of British Columbia study of 38 women with an eating disorder whowere taught to knit found that learning the craft led to significant improvements. Seventy-four percent of the women said the activity lessened their fears and kept themfrom thinking about their problem.

L) Betsan Corkhill, a wellness coach in Bath, England, and author of the book Knit forHealth & Wellness, established a website, Stitchlinks, to explore the value of whatshe calls therapeutic knitting. Among her respondents, 54 percent of those who wereclinically depressed said that knitting made them feel happy or very happy. In a studyof 60 self-selected people with persistent pain, Ms. Corkhill and colleagues reported thatknitting enabled them to redirect their focus, reducing their awareness of pain. Shesuggested that the brain can process just so much at once, and that activities likeknitting and crocheting make it harder for the brain to register pain signals. Perhapsmost exciting is research that suggests that crafts like knitting and crocheting may helpto keep off a decline in brain function with age. In a 2011 study, researchers led by Dr. Yonas Geda at the Mayo Clinic in Rochester interviewed a random (随机的) sample of1,321 people ages 70-89, most of whom were cognitively (在认知方面) normal, about thecognitive activities they engaged in late in life. The study, published in the Journal ofNeuropsychiatry & Clinical Neurosciences, found that those who engaged in craftslike knitting and crocheting had a diminished chance of developing mild cognitivedisorder and memory loss.

M) Although it is possible that only people who are cognitively healthy would pursuesuch activities, those who read newspapers or magazines or played music did not showsimilar benefits. The researchers speculate that craft activities promote thedevelopment of nerve pathways in the brain that help to maintain cognitive health.

N) In support of that suggestion, a 2014 study by Denise C. Park of the University ofTexas at Dallas and colleagues demonstrated that learning to knit or do digitalphotography enhanced memory function in older adults. Those who engaged inactivities that were not intellectually challenging, either in a social group or alone, did not show such improvements.

O) Given that sustained social contacts have been shown to support health and a longlife, those wishing to maximize the health value of crafts might consider joining a groupof like-minded folks. I for one try not to miss a single weekly meeting of my knittinggroup.

36. When the author was a college student, she found that knitting helped herconcentrate.

37. Knitting can help people stay away from tobacco.

38. Even men and children are now joining the army of knitters.

39. Being a member of a crafts group enhances one's health and prolongs one's life.

40. Knitting diverts people's attention from their pain.

41. The author learnt to knit as a teenager, but it was not until she was much older thatshe became keenly interested.

42. When people are knitting, they tend to eat fewer snacks.

43. Survey findings show that knitting can help people relieve stress.

44. According to a study, knitters and crocheters are less likely to suffer mild cognitivedamage.

45. The products of knitting can increase one's sense of self-respect.

Section C

Directions: There are 2 passages in this section. Each passage is followed by somequestions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter onAnswer Sheet 2 with a single line through the centre.

Passage One

Questions 46 and 50 are based on the following passage.

Nobody really knows how big Lagos is. What's indisputable is that it's growing veryquickly. Between now and 2050, the urban population of Africa could triple. Yet cities insub-Saharan Africa are not getting richer the way cities in the rest of the world have. Most urban Africans live in slums (贫民窟); migrants are often not much better off thanthey were in the countryside. Why?

The immediate problem is poverty. Most of Africa is urbanising at a lower level ofincome than other regions of the world did. That means there's little money around forinvestment that would make cities liveable and more productive. Without upgrades andnew capacity, bridges, roads and power systems are unable to cope with expandingpopulations. With the exception of South Africa, the only light rail metro system in sub-Saharan Africa is in Addis Ababa, Ethiopia. Traffic jam leads to expense andunpredictability, things that keep investors away.

In other parts of the world, increasing agricultural productivity and industrialisationwent together. More productive farmers meant there was a surplus that could feedcities; in turn, that created a pool of labour for factories. But African cities are different. They are too often built around consuming natural resources. Government isconcentrated in capitals, so is the money. Most urban Africans work for a smallminority of the rich, who tend to be involved in either cronyish (有裙带关系的) businesses or politics. Since African agriculture is still broadly unproductive, food isimported, consuming a portion of revenue.

So what can be done? Though African countries are poor, not all African cities are. InLagos, foreign oil workers can pay as much as $65,000 per year in rent for a modestapartment in a safe part of town. If that income were better taxed, it might provide therevenue for better infrastructure. If city leaders were more accountable to their residents, they might favour projects designed to help them more. Yet even as new roads are built, new people arrive. When a city's population grows by 5% a year, it is difficult to keepup.

46. What do we learn from the passage about cities in sub-Saharan Africa?

A) They have more slums than other cities in the world.

B) They are growing fast without becoming richer.

C) They are as modernised as many cities elsewhere.

D) They attract migrants who want to be better off.

47. What does the author imply about urbanisation in other parts of the world?

A) It benefited from the contribution of immigrants.

B) It started when people's income was relatively high.

C) It benefited from the accelerated rise in productivity.

D) It started with the improvement of peopled livelihood.

48. Why is sub-Saharan Africa unappealing to investors?

A) It lacks adequate transport facilities.

B) The living expenses there are too high.

C) It is on the whole too densely populated.

D) The local governments are corrupted.

49. In what way does the author say African cities are different?

A) They have attracted huge numbers of farm labourers.

B) They still rely heavily on agricultural productivity.

C) They have developed at the expense of nature.

D) They depend far more on foreign investment.

50. What might be a solution to the problems facing African cities?

A) Lowering of apartment rent.

B) Better education for residents.

C) More rational overall planning.

D) A more responsible government.

Passage Two

Questions 51 to 55 are based on the following passage.

For the past several decades, it seems there's been a general consensus on how to getahead in America: Get a college education, find a reliable job, and buy your own home. But do Americans still believe in that path, and if they do, is it attainable?

The most recent National Journal poll asked respondents about the American dream, what it takes to achieve their goals, and whether or not they felt a significant amount ofcontrol over their ability to be successful. Overwhelmingly, the results show that today, the idea of the American dream—and what it takes to achieve it—looks quite differentthan it did in the late 20th century.

By and large, people felt that their actions and hard work—not outside forces—were thedeciding factor in how their lives turned out. But respondents had decidedly mixedfeelings about what actions make for a better life in the current economy.

In the last seven years, Americans have grown more pessimistic about the power ofeducation to lead to success. Even though they see going to college as a fairly achievablegoal, a majority—52 percent—think that young people do not need a four-year collegeeducation in order to be successful.

Miguel Maeda, 42, who has a master's degree and works in public health, was the first inhis family to go to college, which has allowed him to achieve a sense of financialstability his parents and grandparents never did.

While some, like Maeda, emphasized the value of the degree rather than the educationitself, others still see college as a way to gain new perspectives and life experiences. Sixty-year-old Will Fendley, who had a successful career in the military and neverearned a college degree, thinks "personal drive" is far more important than just going tocollege. To Fendley, a sense of drive and purpose, as well as an effective high-schooleducation, and basic life skills, like balancing a checkbook, are the necessaryingredients for a successful life in America.

51. It used to be commonly acknowledged that to succeed in America, one had to have .

A) an advanced academic degree

B) an ambition to get ahead

C) a firm belief in their dream

D) a sense of drive and purpose

52. What is the finding of the latest National Journal poll concerning the Americandream?

A) More and more Americans are finding it hard to realize.

B) It remains alive among the majority of American people.

C) Americans' idea of it has changed over the past few decades.

D) An increasing number of young Americans are abandoning it.

53. What do Americans now think of the role of college education in achieving success?

A) It still remains open to debate.

B) It has proved to be beyond doubt.

C) It is no longer as important as it used to be.

D) It is much better understood now than ever.

54. How do some people view college education these days?

A) It promotes gender equality.

B) It needs to be strengthened.

C) It adds to cultural diversity.

D) It helps broaden their minds.

55. What is one factor essential to success in America, according to Will Fendley?

A) A desire to learn and to adapt.

B) A strong sense of responsibility.

C) A willingness to commit oneself.

D) A clear aim and high motivation.

Part IV Translation

Mount Hua is located in Huayin City (Shaanxi, China), 120 kilometers away from Xi'an. Itis part of the Qin Mountains, which divide not only northern and southern Shaanxi, butalso south and north China. Unlike Mount Tai that used to be frequented by pilgrims, Mount Hua was not well visited by pilgrims as the roads up the mountain wereextremely dangerous. Back then, however, those who wished to enjoy longevityventured in Mount Hua quite a lot because numerous herbs, rare ones in particular, grew in the mountain. Since cable cars were installed in Mount Hua in the 1990s, thenumber of visitors has increased dramatically.
