Far from the land of Antarctica, a huge shelf of ice meets the ocean. At the underside of the shelf ther
e 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? There must be some secrets. 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 it
s 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 stra
nge things made up of a protein(蛋白质) never seen in the blood of a fish before. 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(分子) 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?
| A．The terrible conditions in the Antarctic. | B．A special fish living in freezing waters. |
| C．The ice shelf around Antarctica. | D．Protection of the Antarctic cod. |
Why can the Antarctic cod live at the freezing temperature?
| A．The seawater has a temperature of -1.88℃. |
| B．It loves to live in the ice-salt mixture. |
| C．A special protein keeps it from freezing. |
| D．Its blood has a temperature lower than -2.05℃. |
What does "glycol-" in the underlined word "glycoprotein" in the last paragraph mean？
| A．sugar | B．ice | C．blood | D．molecule |

Here is some must-know information from a handbook on how people behave in doing business in some countries.
In Brazil
Brazilians are warm and friendly. They often stand close when talking and it is common for them to touch the person on the shoulder. People often greet each other (particularly women) with light cheek kisses. Schedules tend to be flexible, with business meetings sometimes starting later than planned. But to be safe, be on time. Meals can stretch for hours—there’s no such thing as rushing a meal in Brazil. Lunches also can start in the mid to late afternoon. Brazilians are social, preferring face-to-face communication over mails or phone calls.
In Singapore
Singaporeans shake hands when they meet and often also greet each other with a small, polite bow. Business cards should be offered and received with two hands. Arriving late is considered disrespectful. So be on time. Efficiency(效率) is the goal, so meetings and dealings often are fast-paced. Singaporeans are direct in their discussions, even when the subject is about money. Rank is important and authority is respected. This determines both people interact in meetings. For example, people avoid disagreeing outright with someone with a higher rank.
In the United Arab Emirates
In the UAE, status is important, so the most senior or oldest should be greeted first with their titles. The handshake seems to be longer than elsewhere. So, do not pull away the handshake. Women should cover themselves when it comes to dress. Men also tend to be covered from neck to elbows(肘部) and down to the knees. People do not avoid entertaining in their homes, but they also hold business meals at restaurants. Touching or passing food or eating with your left hand is to be avoided. When meetings are one-to-one, if your host offers you coffee, you should refuse. It might seem odd, but it is a cultural tradition. Coffee should only be accepted if it is always set out or presented.
In Switzerland
The Swiss tend to be formal and address each other by last name. They also are respectful of private lives. You should be careful not to ask about personal topics. Punctuality (守时) is vital, something that comes from a deep respect for others’ time. Arrive at any meeting or event a few minutes early to be safe. They also have clear structure in their companies. Higher-ups make the final decisions, even if others might disagree. Neat, clean dress is expected. The Swiss follow formal table manners. They also keep their hands visible at the table and their elbows off the table. It is polite to finish the food on your plate.The passage is mainly about ________.

I was never very neat, while my roommate Kate was extremely organized. Each of her objects had its place, but mine always hid somewhere. She even labeled（贴标签）everything. I always looked for everything. Over time, Kate got neater and I got messier. She would push my dirty clothing over, and I would lay my books on her tidy desk. We both got tired of each other.
War broke out one evening. Kate came into the room. Soon, I heard her screaming. “Take your shoes away! Why under my bed!” Deafened, I saw my shoes flying at me. I jumped to my feet and started yelling. She yelled back louder.
The room was filled with anger. We could not have stayed together for a single minute but for a phone call. Kate answered it. From her end of the conversation, I could tell right away her grandma was seriously ill. When she hung up, she quickly crawled（爬）under her covers, sobbing.
Obviously, that was not something she should not go through alone. All of a sudden, a warm feeling of sympathy rose up in my heart.
Slowly, I collected the pencils, took back the books, made my bed, cleaned the socks and swept the floor, even on her side. I got so into my work that I even didn’t notice Kate had sat up. She was watching, her tears dried and her expression one of disbelief. Then, she reached out her hands to grasp mine. I looked up into her eyes. She smiled at me, “Thanks.”

When I told my father that I was moving to Des Moines, Iowa, he told me about the only time he had been there. It was in the 1930s, when he was an editor if the literary magazine of Southern Methodist University（SMU）in Dallas, Texas. He also worked as a professor at SMU, and there was a girl student in his class who suffered from a serious back disease. She couldn;t afford the operation because her family was poor.
Her mother ran a boardinghouse in Galveston, a seaside town near Houston, Texas. She was cleaning out the attic（阁楼）one day when she came across an old dusty manuscript（手稿）. On its top page were the words, “By O. Henry”. It was a nice story, and she sent it to her daughter at SMU, who showed it to my father. My father had never read the story before, but it sounded like O. Henry, and he knew that O. Henry had once lived in Houston. So it was possible that the famous author had gone to the beach and stayed in the Gainestown boardinghouse, and had written the story there and left the manuscript behind by accident. My father visited an O. Henry expert at Columbia University in New York, who authenticated the story as O. Henry’s.
My father then set out to sell it. Eventfully, he foud himself in Des Moines, meeting with Gardner Cowles, a top editor at the Des Moines Register. Cowles loves the story and bought it on the spot. My father took the money to the girl. It was just enough for her to have the operation she so desperately needed.
My father never told me what the O. Henry story was about. But i doubt that it could have been better than his own story.Who found the O. Henry’s manuscript?
| A．The girl’s mother. | B．The author’s father. |
| C．The girl. | D．The author. |
Which of the following might explain the fact that the manuscript was found in the attic?
| A．O. Henry once worked in Houston. |
| B．O. Henry once stayed in Galveston. |
| C．O. Henry once moved to Des Moines. |
| D．O. Henry once taught at SMU. |
The underlined word “authenticated” in Paragraph 2 probably means __________.

Bursting into the classroom from recess, 15 children take their seats and face the woman they know as Ms. Yang.
“What day is it today?” she asks, in Mandarin Chinese.
“Confucius’ birthday!” the fifth graders shout in Mandarin.
“Why do we celebrate Confucius’ birthday?”
“Because he’s the greatest teacher in the history of China!” exclaims a brown-haired girl. She is speaking Mandarin.
English is rarely heard in Lisa Yang’s class at the Chinese American International School(CAIS), despite the fact that few students are native speakers of Mandarin.
The United States is actively trying to increase the group of students in “critical languages” such as Mandarin. The students at CAIS are way ahead in such a trend.
Founded 25 years ago, this small private school in San Francisco, USA, does what few other American schools do: It produces fully fluent speakers of Mandarin Chinese, by far the most commonly spoken language in the world.
Mandarin Chinese is suddenly hot in American schools. As China becomes the world’s leading economy sometimes this century, schools in the U. S. are scrambling to add Mandarin to their list of foreign languages or expand Chinese programs already in place.
“It really is almost unprecedented. People are looking at China as a force to be reckoned with… And to ensure that the U. S. has the ability to conduct trade, and to work with the Chinese. Certainly having an understanding of Chinese language and culture is an advantage,” said Marty Abbott of the American Council on the Teaching of Foreign Languages(ACTFL).
To develop Chinese-language programs has not been smooth. A shortage of trained teachers has made it difficult for some schools to join the race. When schools do get teachers, they often hire them straight from China, and the teachers usually suffer culture shock when they come to the U. S.
Robert Liu remembers his first two years in an American classroom It was not an easy adjustment. “In China, students respect their teachers,” he said. Liu found that American students, however, expect an active teaching style. He had to use games to engage them rather than lectures.
To avoid many of the problems with foreign teaching styles, the CAIS has been working with the Chinese government to improve training of teachers who are sent to the U. S.Which of the following is NOT true according to the passage?
| A．Understanding Chinese language and culture is helpful to work with Chinese. |
| B．Chinese-language programs have met trouble during the development. |
| C．Many other American schools do the same as CAIS, founded 25 years ago. |
| D．A lack of trained Mandarin Chinese teachers is a problem for the programs. |
What kind of problem is the most difficult to adjust in teaching Chinese in America?
| A．To adapt themselves to the American life styles. |
| B．To communicate with the American students. |
| C．To get along well with the American students. |
| D．To be fit for the cultural differences in teaching styles. |
The meaning of the underlined word “scrambling” is similar to .
| A．climbing | B．rushing |
| C．changing | D．beating |
It can be learned from the passage that .
| A．the students in Lisa Yang’s class usually speak Chinese |
| B．There are few American students in Lisa Yang’s class |
| C．We celebrate Confucius’ birthday because he’s the greatest history teacher |
| D．in America the students don’t respect their teachers |
