Learning How to See

I believe in the importance of seeing something new each time we see the familiar and seeing into and beyond the words we hear.

In high school, I had a teacher who made me 21 of these concepts, although it took many years before I 22 them fully.

One day, Mrs. Lambert, my advanced placement English teacher, brought in several 23 filled with all kinds of things. Each of us 24 took something and wrote a(n) 25 about it for homework. The next day, the baskets 26 again, and we were instructed to select the 27 object. This time we had to write a composition about the object without 28 anything from the first one.

Over the next few days the same thing 29 , with each day bringing an increasing 30 of frustration as we tried to see something 31 in an otherwise uninteresting object. I will never forget the last 32 I wrote about my blue and white Delft fisher boy. After 33 to find something original to say, I 34 got inspired to write a poem. It 35 me to see beyond the porcelain figurine（瓷器人）and into the 36 of the character. Mrs. Lambert had shown me how to use my own 37 and creativity to see what I otherwise would have looked at and disappeared immediately.

Fifty years 38 , as I remember Mrs. Lambert, I wonder, are schools today showing

kids how to use their own eyes and ears to see into and 39 the surface? This, I believe, is the most important 40 a child can take into adulthood.

第一节：阅读下列材料，从每题所给的四个选项(A、B、C、D)中选出最佳选项并在答题纸上将该选项标号涂黑。

A

Alexis, 17, sat quietly in the passenger seat of her dad's car. She let her eyes lazily scan the landscape for wildlife. Then a deer came into view about 200 yards in front of them. "Dad, there's a deer there!" Alexis said. It was a male deer with sharp antlers (角) on each side of its head.

As the car moved closer, Alexis saw that the deer's head was bent toward the ground. Then she heard a scream and saw an arm fly up near the deer's head. Alexis realized the deer was attacking a woman. Sue, a 44-year-old mother, had been out for her morning run. The deer followed her and edged closer. "I knew I was in trouble," Sue says. She went to pick up a stick for self-defense, and the deer charged. It lifted her with its antlers and threw her into the air. Sue could feel blood flew down her leg. Within seconds, the deer had pushed her off the road.

When Alexis and her father pulled up, the deer was throwing Sue like a doll. Alexis looked into the woman's terrified eyes, and before her father had even stopped the car, the teenager jumped quickly out of the car and ran toward the deer. "I was kicking it to get its attention," she says. Then her father, who had followed his daughter, pushed the deer away from the women.

Alexis helped Sue into the car, and then applied a piece of cloth to Sue's injured leg. "We're going to get you to a hospital," Alexis said. Then she heard her father shout loudly. He had been knocked to the ground. Alexis took hold of a hammer from the car and ran to where her father lay on his back. She beat the deer's head and neck, but the blows didn't scare it away. "I was losing faith," she says. "A couple more strikes, Alexis," said her father. "You can do it." Turning the hammer around, Alexis closed her eyes and beat the deer's neck with all her strength. When she opened her eyes, the deer was running away. Alexis got in the driver's seat and sped toward the nearest hospital.

After Sue was treated, she tearfully thanked her rescuers. "You expect a teenage girl to get on the phone and call for help," she says, "not to beat up a deer."

41. What was Sue doing when she was attacked by the deer?

A. She was driving home.

B. She was resting on the road.

C. She was taking exercise.

D. She was feeding wild animals.

B. rushed in an attack

C. accused sb

D. stored electricity

43. What did Alexis do to save Sue at first?

A. She pushed the deer away.

B. She hit the deer with her feet

C. She drove the car to hit the deer.

D. She beat the deer with a hammer.

44. Which of the following words can best describe Alexis?

A. Strong.

B. Cruel.

C. Energetic.

D. Brave.

45. What is the best title for the passage?

A. A Woman Was Seriously Injured

Below is a selection of 8 unusual scientists who did research.

1. Wan tried to ride a rocket chair. You have to hand it to Wan Hu. Legend has it that when the Chinese official, Wan Hu, decided to visit the moon, he didn’t ask one of his servants to sit in the hot seat. He settled himself into a wood chair fixed with 47 rockets. When 47 torch-bearing assistants lit the rockets, there was a loud sound and lots of smoke--but no more Wan Hu. There is, however, a crater named for Wan Hu on the far side of the moon.

2. Isaac Newton stuck a needle in his eye. Though best known for discovering the laws of gravitation, Newton also did pioneering research in optics. He experimented with prisms（棱镜）, but that didn’t reveal much about the eye’s structure or how it senses color. To learn more, the unusual physicist took a type of needle known with a sharp tip and, he wrote, “put it between my eye and the bone as near to the backside of my eye as I could.”

3. Nicolae Minovici hanged himself. Nicolae Minovici performed a series of experiments in which he allowed himself to be choked by ropes. Though his feet reportedly never left the ground, he experienced a burning pain in his neck and signaled to be lowered. He had trouble swallowing for an entire month.

4. Franz Reichelt tested his parachute by jumping from the Eiffel Tower. On Feb 4, 1912, an Austrian-born tailor named Franz Reichelt tested his “parachute（降落伞）suit” -- an airman’s suit designed to function as a parachute in the event of an emergency. Alas, the chute failed to open up, which contributed to his death. The event was recorded in still photos as well as in the grainy video below.

5. Evan O'Neill Kane took out his own appendix（阑尾）. Dr. Kane, a surgeon working in Pennsylvania in the early 20th Century, wanted to find out about appendix. On Feb. 15, 1921, he chose to perform the surgery himself and take out his appendix. But he calmly pushed them back

in and kept working.

6. Werner Forssmann stuck a plastic tube in his own heart. In the early part of the last century, it was believed that inserting something into a beating heart would be deadly. Werner Forssmann thought otherwise. So one day in 1929, he put a tube into his heart. Fortunately he survived the daring experiment but lost his job. But his fearlessness was rewarded when he won a Nobel Prize in 1956.

7. Frederick Hoelzel ate glass. And not just glass. During the 1920s and 1930s, University of Chicago researcher Frederick Hoelzel reportedly swallowed grain, glass, ball bearings, thread, wire, and other non-food items in order to show how long it would take the items to pass through his guts（肠子）. Despite his risky research, Hoelzel lived into old age.

8. Barry Marshall drank bacteria-loaded soup.For many years doctors had only an unclear idea about the cause of stomach illness. So he decided to be his own pig, taking germs from an infected patient, mixing them in a solution, and drinking it. A few days later, after experiencing a period of throwing up and tiredness, he examined his own gut--and proved the link between the germs and illness. For his daring experiment he won a Nobel Prize in 2005.

46. Which of the following scientist’s research certainly was recorded by video?

A. Newton.

B. Minovici.

C. Hoelzel.

D. Reichelt.

47. Why did Werner Forssmann and Barry Marshall win the Nobel Prize?

A. The two scientists were expert in surgery operations.

B. Both discovered the links between germs and disease.

C. They made significant breakthroughs in medical research through their brave experiments.

D. Each of them conducted the same experiment separately.

48. In which experiment did a scientist lose his life?

A. Riding a rocket chair.

B. Eating glass.

C. Sticking a needle in his eye.

D. taking out his own appendix.

49. The greatest difference of the 8 scientists from the majority of other scientists is that_______.

A. they devoted their time to scientific research

B. they would risk their lives for experiments

C. they were greatly enthusiastic about science

D. they made their great contributions to science

C

Computer power is moving into the “cloud”—networks of data centres that use the Internet to supply all kinds of services, from e-mail and social networks to data storage and analysis.

The rise of cloud computing is rapid and causing huge changes in the tech industry. The old guard is suffering: this week’s $67 billion merger (合并) between Dell and EMC, makers of computers and storage devices respectively (分别), was a marriage forced by the rise of the cloud.

The gains for customers have been equally dramatic. Compared with older IT systems, cloud computing is often much cheaper. It adds tremendous flexibility: firms that need more computing capacity no longer have to spend weeks adding new servers and installing software. In the cloud they can get hold of it in minutes. Their applications can be updated continually, rather than just every few months. Individual users can reach their e-mails, files and photos from any device. And cloud services also tend to be more secure, since providers know better than their customers how to protect their computing systems against hackers.

But cloud computing makes one problem worse. In the old IT world, once a firm or a consumer had decided on an operating system or database, it was difficult and costly to switch to another. In the cloud this “lock-in” (锁定)is even worse. Cloud providers try their best to make it easy to upload data. They accumulate huge amounts of complex information, which cannot easily be moved to an alternative provider.

Cloud firms also create a world of interconnected services, software and devices, which is convenient but only for as long as you don’t venture outside their universe. Being locked in to a provider is risky. Firms can start to tighten the screws by increasing prices. If a cloud provider goes bust (崩溃), its customers may have trouble getting back their data.

These risks have already caused a debate about whether the cloud needs stricter regulation. Some European politicians want to force cloud providers to ensure that data can be moved between them. That is too heavy-handed, because strict rules will prevent innovation in what is still a young industry. The history of computing suggests that common standards may well appear naturally in response to customers’ demands—just as in personal computers, where it is now much easier to use the same files on different systems.

In the meantime, a few commonsense measures can reduce the risk of lock-in. Firms that use more than one cloud provider to host their data are less affected. So are those that keep their most important information in their own data centres. Consumers can take precautions, too. Some services are better than others at enabling users to move data between providers (Google does well on this score). Cloud computing promises its users many benefits, but don’t mistake it for some sort of digital heaven.

50. The author takes “the merger between Dell and EMC” for example to show ________.

A. the influence of cloud computing on computer and storage device makers

B. the miserable sufferings of old computer companies

C. the rapid development of new computer companies

D. the interaction between old companies and newcomers

51. With wide applications of cloud computing customers can ________.

A. pay less for the older IT systems

B. gain more computing capacity quickly

C. know better about defeating the hackers

D. install software within weeks

52. The problem of “lock-in” can be dangerous because ________.

A. it should ensure data can easily be moved to another provider

B. it can create a network of services connected with devices

C. it may make it difficult for customers to recover their data

D. it will discourage an argument about stricter rules

53. It can be inferred from the last two paragraphs that ________.

A. the European politicians’ advice is perfect

B. customers’ demands play a role in setting st andards

C. lock-in is caused by firms’ storing information in their own centres

D. Google enables users to provide services and move data

54. Which of the following sayings can best express the main idea of the passage?

A. Everything has its time and that time must be watched.

B. The grass looks greener on the other side of the fence.

C. A candle lights others and consumes itself.

D. Every white has its black, and every sweet has its sour.

D

For many people, particularly immigrants, the American Dream is that talent and hard work can take you from log cabin to the White House. Tony Trivisonno did not rise as high as the White House, yet he managed to make his own dream come true.

He came from a farm in Italy. One evening I found him standing behind my garage.

"I mow (割草) your lawn," he said. It was hard to comprehend his broken English.

I asked him his name. "Tony Trivisonno," he replied. "I mow your lawn." I told Tony that I couldn't afford a gardener.

"I mow your lawn," he said again, then walked away. Yes, these Depression days were difficult, but how could I refuse a person who had come to me for help?

When I got home from work the next evening, the lawn had been mowed and the walks swept. I asked my wife what had happened.

"A man had worked on the yard," she answered. "I thought you had hired him."

I told her of my experience the night before. We thought it strange that Tony had not asked for pay.

The next Friday, I saw Tony again, behind the garage. I praised him for the work he had done.

"I mow your lawn," he said.

I managed to give him some kind of small weekly pay, and each day Tony cleaned up the yard and took care of any little tasks. My wife said he was very helpful whenever there were anything heavy to lift or things to fix.

Summer passed into fall, and winds blew cold. "Mr. Craw, snow pretty soon," Tony told me one evening. "When winter comes, you give me job clearing snow at the factory."

Well, how do you deal with such determination and hope? Of course, Tony got his job at the factory.

One day I found Tony at our meeting place behind the garage. "I want to be apprentice (学徒)" he said.

We had a pretty good apprentice school that trained workers. But I doubted whether Tony were able to read blueprints or do precision work. Still, how could I turn him down?

Tony took a cut in pay to become an apprentice. Months later, I got a report that he had graduated as a skilled grinder (磨工). My wife and I were delighted with what Tony had achieved.

A year or two passed, and again I found Tony in his usual waiting place. "Mr. Craw," he said, "I like to buy a house." In the town, he had found a completely old house for sale.

I called on a banker friend. "Do you ever loan money on character?" I asked. "No," he said.

"Now, wait a minute," I replied. "Here is a hard-working man, a man of character, I can promise you that. He's got a good job. And he will pay your interest."

Unwillingly, the banker loaned Tony $2,000 and helped him buy the house. Tony was delighted. From then on, it was interesting to see that any abandoned odds and ends around our place were gathered and taken home by Tony.

After about two years, I found Tony in our familiar meeting spot. He seemed to stand a little straighter and looked confident.

"Mr. Craw, I sell the house and buy a farm."

We sat down and talked. He told me that he had persuaded his childhood friend to move to America. With a satisfied look in his eye, he told me that when they came to his little farm, his friend stood in amazement and said, "Tony, you are a millionaire!"

Then, during the World WarⅡ, news came from my company that Tony had passed away.

When my people came to visit his family, they found the farm green with vegetables, the little house comfortable and homey. The children were educated and working, and Tony didn't owe a cent.

Tony, as well as all the greatest American businessmen, had reached their success in the same way and by the same values: vision, determination, optimism, self-respect and, above all, honesty.

Tony Trivisonno came to America seeking the American Dream. But he didn't find it — he created it for himself. All he had were 24 precious hours a day, and he wasted none of them.

55. Why did Tony repeat “I mow your lawn”?

A. He was determined to get a chance to work.

B. He asked for pay for his excellent garden work.

C. He thought he was good at garden work.

D. He was ready to help others out.

56. Which of the following sentences brought out Tony’s character of honesty?

A. Tony was very helpful whenever there were anything heavy to lift or things to fix.

B. Tony persuaded his childhood friend to move to America.

C. Any abandoned odds and ends around our place were gathered and taken home by Tony.

D. The children were educated and working, and Tony didn't owe a cent.

57. What did the author mean by saying “Do you ever loan money on character”?

A. He was asking the banker the way the banks loan money to people.

B. He thought a determined and diligent man should get a loan despite poverty.

C. He was begging the banker to help Tony for the sake of their personal relation.

D. He supposed a loan should be given to people according to their characters.

58. The fact that Tony sold his house and bought a farm indicated that Tony is a man of ____.

A. vision

B. optimism

C. self-respect

D. honesty

59. Which of the following is TRUE according to the passage?

A. The author refused Tony’s offer of mowing the lawn when they first met.

B. The author didn’t pay To ny for his cleaning up the yard.

C. The author doubted Tony’s being a good apprentice due to his poor education.

D. The banker loaned Tony $ 2,000 because he believed Tony was honest.

60. Which of the following is probably the best title for the passage?

A. How to achieve the American Dream

B. Italian immigrants’ life in America

C. Tony Trivisonno’s American Dream

D. Honesty and determination make success

How to Become Best Friends with Your Dormmates

You have never shared a room with anyone and now you are scared and confused. But do you know that student years are one of the most exciting and memorable? When I was a student I met

lots of great people and my best friend as well. Sharing a room with absolutely unknown person might be challenging at first, but it will be a priceless experience in your life. Check out several tips on how to become best friends with your dormmates.

61. ____________

This is the essential rule of any go od relationship. Make a list of the things that are/aren’t allowed to both of you and stick to it. Decide on the studying time, cleaning and visiting hours. Not only will it make your routine easier, but can also help to avoid misunderstandings and quarrel s. It’s important to talk about male guests and overnight visitors. If needed, you may set some rules for your visitors. When I was a student our room was frequently full of friends and visitors, but I tried not to turn it into the social center.

62. ____________

You will escape many fights if you start talking about the problem once you feel it’s necessary. When you accumulate the little things, they grow bigger and chances are you will say a lot of unpleasant things you don’t really mean. Your dormmate s simply cannot know or notice some things. That’s why negotiations are always the right thing to consider. My dormmate was always forgetting to take away her wet towel from the dresser and it was just unbearable. When she performed the same thing for several times, I explained that it was a bit irritating and an annoying bad habit. That’s it.

63. ___________

Common memories and experience are the right things that pull people together. You are newcomers and you have no idea about the territory of the campus. So why not explore the campus together? Generally speaking, any activity you can share will be of advantage. You can become workout buddies or you may turn out to be the fans of the same band.

64. ____________ I really appreciate togetherness and I was always a good mixer, but sometimes even such an easygoing person like me needs some personal space and me-time. You spend every minute together and you need to take a break once in a while. It’s absolutely okay. Discuss this question wi th your dormmates well in advance so that you won’t have any problems during the school year.

65. ____________

This tip will help you to get along with the dormmate and will help you go far in life as well.

Your dormmates may be from other countries with different traditions, religion and views. Be careful with the stereotypes and prejudgment, your ideas about the subject may be superficial and incorrect. Most probably your overseas dormmates will need some help during the period of adaptation to the new surrounding and lifestyle. Sharing a room with an international student is a unique chance to learn another culture and language. Don’t

miss it!

It appears that people don't need phone boxes now. In the small British village, people decided to turn a red phone box for a library a few years before. Now, the phone box is one of the country’s smallest libraries. About 150 books have placed in t he phone box. Villagers can take whatever they want and leave his own books there. They can use the library around the clock so it opens 365 days a year and 24 hours a day. Since the library opens its door, people from all parts of the village have paid a visit to it, among it there're senior citizens living in the neighborhood, children getting off school buses and university students are stopping by at night.
