Far from the land of Antarctica, a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod.
For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer.
Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish’s blood and measured its freezing point.
The fish were taken from seawater that had a temperature of -1.88℃ and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to -2.05℃. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture.
The scientists’ next research job was clear: Find out what in the fish’s blood kept it from freezing. Their search led to some really strange thing made up of a protein never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.
Study showed that it is an unusual kind of protein. It has many small sugar molecules held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein. Or AFGP.What is the text mainly about?

There were smiling children all the way. Clearly they knew at what time the train passed their homes and they made it their business to stand along the railway, wave to complete strangers and cheer them up as they rushed towards Penang. Often whole families stood outside their homes and waved and smiled as if those on the trains were their favorite relatives. This is the simple village people of Maiaysia. I was moved.
I had always traveled to Malaysia by plane or car, so this was the first time I was on a train. I did not particularly relish the long train journey and had brought along a dozen magazines to read and reread. I looked about the train. There was not one familiar face. I sighed and sat down to read my Economics.
It was not long before the train was across the Causeway and in Malaysia. Johore Baru was just another city like Singapore, so I was tired of looking at the crowds of people as they hurried past. As we went beyond the city, I watched the straight rows of rubber trees and miles and miles of green. Then the first village came into sight. Immediately I came alive. I decided to wave back.
From then on my journey became interesting. I threw my magazines into the waste basket and decided to join in Malaysian life. Then everything came alive. The mountains seemed to speak to me. Even the trees were smiling. I stared at everything as if I was looking at it for the first time.
The day passed fast and I even forgot to have my lunch until I felt hungry. I looked at my watch and was surprised that it was 3:00 pm. Soon the train pulled up at Butterworth. I looked at the people all around me. They all looked beautiful. When my uncle arrived with a smile, I threw my arms around him to give him a warm hug （拥抱）. I had never done this before. He seemed surprised and then his weather-beaten face warmed up with a huge smile. We walked arm in arm to his car.

Short and shy, Ben Saunders was the last kid in his class picked for any sports team. "Football, tennis, Cricket—anything with a round ball, I was useless." he says now with a laugh. But back then he was the object of jokes in school gym classes in England's rural Devonshire.
It was a mountain bike he received for his 15th birthday that changed him. At first the teen went biking alone in a nearby forest. Then he began to cycle along with a runner friend. Gradually, Saunders set his mind on building up his body, increasing his speed, strength and endurance. At age 18, he ran his first marathon.
The following year, he met John Ridgway, who became famous in the 1960s for rowing an open boat across the Atlantic Ocean. Saunders was hired as an instructor at Ridgway's school of Adventure in Scotland, where he learned about the older man's cold-water exploits（成就）. Intrigued, Saunders read all he could about Arctic explorers and North Pole expeditions, then decided that this would be his future.
Journeys to the Pole aren't the usual holidays for British country boys, and many people dismissed his dream as fantasy." John Ridgway was one of the few who didn't say, 'You are completely crazy,'" Saunders says.
In 2001, after becoming a skilled skier, Saunders started his first long-distance expedition toward the North Pole. He suffered frostbite, had a closer encounter（遭遇）with a polar bear and pushed his body to the limit.
Saunders has since become the youngest person to ski alone to the North Pole, and he's skied more of the Arctic by himself than any other Briton. His old playmates would not believe the transformation.
This October, Saunders, 27, heads south to explore from the coast of Antarctica to the South Pole and back, an 1800-mile journey that has never been completed on skis.The turning point in Saunders' life came when _________.

Sixteen years ago I learned this lesson in the back of a New York City taxi cab. Here’s what happened. I hopped in a taxi, and we took off for Grand Central Station. We were driving in the right lane when, all of a sudden, a black car jumped out of a parking space right in front of us. My taxi driver slammed on his brakes, skidded, and missed the other car’s back end by just inches!
The driver of the other car, who almost caused a big accident, started yelling bad words at us. My taxi driver just smiled and waved at the guy. And I mean he was friendly. So, I said, “Why did you just do that? This guy almost ruined your car and sent us to the hospital!” And this is when my taxi driver told me what I now call “The Law of the Garbage Truck. ”
Many people are like garbage （rubbish） trucks. They run around full of garbage, full of frustration, full of anger, and full of disappointment. As their garbage piles up, they need a place to dump it. And if you let them, they’ll dump it on you. When someone wants to dump on you, don’t take it personally. You just smile, wave, wish them well, and move on. You’ll be happy with what you did.
I started thinking, how often do I let Garbage Trucks run right over me? And how often do I take their garbage and spread it to other people at work, at home, or on the streets? It was that day I said, “I’m not going to do anymore.”
Successful people do not let Garbage Trucks take over their day. What about you? If you let more garbage trucks pass you by, you’ll be happier. Life’s too short to wake up in the morning with regrets. So, Love the people who treat you right. Forget about the ones who don’t. What happened one day when the author was taking a taxi?

Why do we laugh and get amusement from so many different things，from puns (双关语) to pratfalls? Why are some things funny to some people and not to others? How is that while a successful joke can cause pleasure，a sick one can cause serious harm?
Over the centuries，various scholars have attempted to produce a universally agreed-upon theory of humor．Plato and Aristotle introduced the superiority(优越感) theory，the idea that people laugh at the misfortune of others．Their theory seems to explain teasing，but it doesn’t work well for knock-knock jokes．Sigmund Freud argued for his relief theory，the concept that humor is a way for people to release psychological tension and reveal their inner fears and desires．His theory works well for dirty jokes，less well for most puns．
The majority of humor expels today agree with the incongruity theory，the idea that humor arises when there’s a gap between what people expect to happen and what actually happens．Incongruity has a lot going for it — jokes with unexpected funny lines，for example，fit well．But scientists have found that in comedy，unexpectedness is overvalued．
With the goal of developing a new，more satisfactory explanation，I produced “the gentle violation(违背)theory”，the idea that humor arises when something seems wrong or threatening，but is actually OK or safe．A dirty joke，for example，trades on moral or social violations，but it’s only going to get a laugh if the person listening is open enough to consider the subject OK to talk about．Similarly，puns can be seen as linguistic violations that still make grammatical sense．
And while most humor theories have struggled to account for tickling (挠痒痒)，or just avoided the phenomenon altogether，my theory accounts for even this kind of laughter．Tickling involves violating someone’s physical space in a gentle way．People can’t tickle themselves — because it isn’t a violation．What is the author’s attitude towards Plato and Aristotle’s theory?
| A．Critical． | B．Approving | C．uncaring | D．Unclear |
According to Sigmund Freud’s theory，we can infer that __________ .
| A．people will laugh when they see others suffer |
| B．telling dirty jokes is a relief of one’s nervous feelings ’ |
| C．unexpectedness can explain how humor works |
| D．tickling doesn’t involve psychological tension |
According to the author，why are some things funny to some people but not to others?
| A．Because the sense of humor varies greatly from person to person． |
| B．Because people have different expectations for the same thing． |
| C．Because some people lack the sense of safety deep in their heart． |
| D．Because people’s understanding of violation is different． |
What is the author’s main purpose of writing this passage?
| A．To draw people’s attention to the research of humor． |
| B．To criticize people’s misconceptions about humor． |
| C．To explain what exactly causes people to laugh． |
| D．To prove the sense of humor can be developed． |
Coffee is a powerful beverage．On a personal level，it helps keep US awake and active．On a much broader level，it has helped shape our history and continues to shape our culture．
Coffee didn’t take off until the l400s when people figured out they could roast its seeds．By the l500s，the drink had spread to coffeehouses across the Arab world．Within another l50 years，it took Europe by storm．
“It actually had a major impact on the rise of business，” historian Mark Pendergrast says．Coffeehouses became a spot not just to enjoy a cup but to exchange ideas．The insurer Lloyd’s of London was founded hundreds of years ago in one of London’s 2,000 coffeehouses．Literature，newspapers and even the works of great composers like Bach and Beethoven were also spawned(涌现)in coffeehouses．
It is often said that after the Boston Tea Party of l773，when American colonists attacked British tea ships and threw boxes of tea into the harbor，Americans universally switched over to drinking coffee．In a letter John Adams wrote to his wife，Abigail，the Founding Father claims his love of tea but says he will have to learn to embrace coffee instead，because drinking tea had become a symbol of not loving the country．
For all the upsides coffee has brought the modern world，it also led to its fair share of downsides，too．Europeans carried coffee with them as they colonized various parts of the world，and this frequently meant they enslaved people in order to grow it．In Brazil — where slavery was legal until l888 — coffee plantations would use slash-and-burn agriculture，tearing down rain forests and planting coffee trees．Once the soil had been exhausted，growers would move on to another place．
And yet，coffee，as Pendergrast says，”had a very good impact in many ways on our civilization，even though it was，for a long time，grown by slaves．”Why did people enjoy going to coffeehouses?
| A．Because it was a fashion to drink coffee． |
| B．Because coffeehouses provided a better flavor． |
| C．Because they could stay awake and active there． |
| D．Because they could exchange ideas there． |
What can we learn from the fourth paragraph?
| A．American colonists made great profits by trading in coffee． |
| B．Tea was regarded as a symbol of loving one’s country． |
| C．Coffee became very popular after the incident in Boston． |
| D．John Adams was the Founding Father of the Tea Party． |
In the fifth paragraph．the writer points out that __________ .
| A．Coffee plantation was closely connected with slavery |
| B．coffee plantation led to outdated agriculture in Brazil |
| C．slavery in Brazil had been against the law until l888 |
| D．slavery was responsible for the damage to rainforests |
What is mainly talked about in this passage?
| A．Some interesting stories about coffee culture． |
| B．Important Roles that coffee played in history． |
| C．How coffee became the most popular beverage． |
| D．How coffee affected America’s independence． |
