I once saw a TV programme at college about a scientist who used “drift bottles (漂流瓶)” to mark ocean currents. It was a rather boring programme. I was more interested to read an article about someone who found a bottle on a beach with a message inside. Like the drift bottles, it had been thrown into the sea — but 21 years before. I decided to find out more about such bottles, and I started work on this intriguing (非常有趣的) research.

An early message in a bottle was thrown into the sea by Christopher Columbus during a terrible storm. He wrote about his discovery of America and expected that his message would be sent to the Queen of Spain. He wanted the news to reach her, but he thought he might be drowned (淹死) in the storm. In fact, he survived but the bottle was never found.

I would be excited to find a message in a bottle, but in the 16th century, it could be dangerous. In those days, the British Navy (海军) used messages in bottles to send information about the enemy. When Queen Elizabeth Ⅰ found out that a boatman had opened a bottle containing one of these secret messages, she created a new job, Uncorker of Ocean Bottles. I was amazed to learn that anyone else who opened a bottle could be sentenced to death. It seems very strange to us now.

A long time ago, before dating websites existed to help people find partners, a sailor in Sweden put this message in a bottle —“To someone beautiful and far away.” It was found by a young woman in Sicily. She answered the message —“I am not

beautiful, but it seems a miracle (奇迹) I found your message.” They began to write letters to each other, and eventually got married.

Nowadays it's easy to communicate with anyone anywhere in the world, but I think people will still go on throwing bottles with messages into the ocean and guessing where the winds and the waves will carry them. And how romantic it would be to find a bottle with a message inside!

24. Why did the author do some research on bottles thrown into the sea?

A. He had found a message in one.

B. He had read an article about one.

C. He had to do a project on them at college.

D. He had watched a TV programme about them.

25. Christopher Columbus put a message into a bottle to .

A. study ocean currents

B. report his discovery

C. ask for rescue

D. try his luck

26. How did the author feel about the 16th century punishment for opening ocean bottles?

A. Frightening.

B. Amusing.

C. Astonishing.

D. Satisfying.

27. Why did the young woman in Sicily reply to the Swedish sailor's message?

A. She wanted to have a pen friend.

B. She felt she fitted his description.

C. She failed to access a dating website.

D. She was impressed by the bottle's journey.

Gene Wolfe is one of the most admired and respected American science fiction and fantasy writers. He is also a productive writer of outstanding short fiction, which

is collected in many volumes over the last forty years, most recently in The Best of Gene Wolfe.

Although Wolfe is not as well-known to readers as he once was, he has been the receiver of great praise, including three World Fantasy Awards, two Nebulas, and eight Hugo Award nominations (提名). Sci-fi author Harlan Ellison has called him, “no less than one of the finest, most original writers in the world today”, and the Encyclopedia of Science Fiction names him “quite possibly the most important” writer in the field of science fiction.

Born in 1931, New York, Gene Wolfe moved frequently as a child, but spent most of his growing-up years in Texas. Wolfe began writing fiction in 1956, selling his first story,The Dead Man, to Sir magazine in 1965. He produced a vast amount of short fiction during the 1960s and 1970s, many of which were published in Damon Knight's Orbit anthologies. In 1972 Wolfe's groundbreaking The Fifth Head of Cerberus appeared. The story of human conquest (征服) upon two distant planets, the book examines issues of identity, individuality, and the results of colonialism upon both the colonized and the colonizer. The novel was later listed in David Pringle's 1985 list of The 100 Best Novels in science fiction for the period

1949―1984.

Many of his novels, The Shadow of the Torturer included, rely on a diary or letter to tell his story. In addition, Wolfe's early interest in mystery novels shines through in his ability to drop cleverly hidden clues (线索) that allow the reader to grasp at the possible narrative behind the narrative.

By 1984 Wolfe was able to retire and devote himself full-time to his writing. Yet despite (尽管) all this, and despite the continuing respect of his colleagues, his work has become somewhat unfamiliar. Wolfe's admirers hope this fact will be at least somewhat improved by his most recent offering, The Wizard Knight, which falls within the fantasy type that is currently popular.

28. What is Harlan Ellison's attitude toward Gene Wolfe?

A. Concerned.

B. Sympathetic.

C. Admiring.

D. Regretful.

29. What do we know about The Fifth Head of Cerberus?

A. It was well received.

B. It was Gene Wolfe's first novel.

C. It was published in Sir magazine.

D. It was co-authored by David Pringle.

30. Which has great influence on Gene Wolfe's writing style?

A. His understanding of life.

B. His childhood experiences.

C. His colleagues' suggestions.

D. His love for mystery fiction.

31. What can we infer about Gene Wolfe from the last paragraph?

A. His work has become less popular.

B. He became famous for The Wizard Knight.

C. His fans were disappointed to some degree.

D. He stopped fantasy writing after his retirement.

The word or phrase that you use to open your email account may provide a key to your personality as well as to your correspondence (信件), according to a British psychologist. Helen Petrie, professor of human / computer interaction (交互作

用) at City, University in London, analysed the responses of 1,200 Britons who participated in a survey funded (提供资金) by CentralNic, an Internet domain name company. The results were recently published on CentralNic's website.

Petrie identifies three main password “types”. “Family oriented” respondents numbered nearly half of those surveyed. These people use their own name or nickname, the name of a child, partner, or pet or a birth date as their password. They tend to be occasional computer users and have strong family ties. “They choose passwords that symbolize people or events with emotional value,” says Petrie. One third of respondents were “fans”, using the names of athletes, singers, movie stars,

fictional characters, or sports teams. Petrie says fans are young and want to attach themselves to the lifestyle represented by a celebrity. Two of the most popular names were Madonna and Homer Simpson. The third main group of participants are “cryptics” because they pick confusing passwords or a random (随机的) string of letters, numbers, and symbols such as “Jxa+157”. Petrie says cryptics are the most security-conscious group. They tend to make the safest but least interesting choices.

Passwords are revealing for two reasons. First, because they are invented on the spot. “Since you are focused on getting into a system, for example your email account, you're likely to write down something that comes quickly to mind,” says Petrie. “In this sense passwords take advantage of things that are just below the surface of consciousness. Also, to remember your password, you pick something that will stick in your mind. You may unconsciously choose something of particular emotional importance.”

32. How did Petrie draw her conclusions?

A. By observing participants' reactions.

B. By interviewing 1,200 people.

C. By studying survey results.

D. By doing an experiment.

33. What do we know about people whose passwords are “family oriented”?

A. They probably have large families.

B. They are likely to be animal lovers.

C. They tend to be social and emotional.

D. They are probably infrequent computer users.

34. What does Pet rie say about the “cryptic” group?

A. They have strong safety awareness.

B. They lack imagination and creativity.

C. They change their passwords regularly.

D. They can't think of an interesting password.

35. Why can passwords reveal our personalities?

A. We choose words we will easily remember.

B. We are willing to invent something personal.

C. We are likely to value important experiences.

D. We pick up a password after careful consideration.

Jacques Cartier

French explorer Jacques Cartier is known chiefly for exploring the St. Lawrence River and giving Canada its name.

Like many other European explorers, Jacques Cartier went to North America looking for gold, spices (香料), and perhaps a shortcut to Asia. 36 It

became France's main route into Canada.

Jacques Cartier was born on December 31, 1491 in Brittany,

a province of France. In about 1534, the king of France asked him to lead an expedition (远征) to the New World in search of riches and a new route to Asia.

37 There he and his crew (船员) explored the land around the Gulf of Saint Lawrence and met Native Americans. When he sailed back to France, he took with him two Native Americans.

38 This time, Cartier sailed deeper into the Gulf of Saint Lawrence and into

the Saint Lawrence River. The two Native Americans he had taken before had learned French, and they served as guides. About 260 miles inland, Cartier reached the Native American village of Stadacona. Today, the city of Quebec stands near that place.

Cartier and his men were among the first Europeans to winter in what is

now Canada. 39 After returning to France he reported tales told by the native people of treasures farther inland.

Cartier once again crossed the Atlantic in 1541. 40 When he returned to France in 1542, he was told that they were just the common minerals pyrite (黄铁矿) (fool's gold) and quartz (石英). After his third voyage Cartier never returned to North America. He died near Saint-Malo, his birthplace, on September 1, 1557.

A. A second voyage came in May 1535.

B. Instead he found the Saint Lawrence River.

C. The bitter cold surprised them, and some of the men died.

D. He made three voyages of exploration in dangerous waters.

E. Cartier was considered one of the most devoted explorers of the period.

F. He explored further and found what he thought were gold and diamonds.

G. In the spring of 1534 Cartier sailed across the Atlantic Ocean to what is

now Canada.

Sleepwalking is most common during the preteen years and may affect 15 percent of children. It tends to run in families. For example, a child is 10 times more likely to sleepwalk if a first-degree 41 such as a parent or a sibling (兄弟姐妹) also sleepwalks. And it's most likely to 42 early in the night, within a few hours of falling asleep. Most 43 outgrow (摆脱) their sleepwalking by the late teen years. Here are some ways to 44 this nighttime behavior.

Make sure you have safety locks on all doors and windows 49 outside, so your child can't leave the house while sleepwalking.

50 your child back to bed. 51 encourage him to go to sleep. 52 sleepwalkers are in the deepest stage of sleep, they will be confused if woken. In addition, 53 the sleepwalkers may disrupt (中断) their sleep, which in turn may cause their

daytime 54 . So if your child is sleepwalking, it's 55 to just tell him to go back to bed, or gently lead him to his room.

Reduce stress. Most often, sleepwalking is the result of emotional 56 . When a second child is born, the older child may be 57 of losing his parents' love. Talk with your child about 58 in his life. If you find your child's sleepwalking might be 59 by some stress in his life, try to 60 it. Get the help of a mental (精神的) health expert if he needs it.
