The journey two divers made some time ago to the deepest point on the earth makes us realize how much of the world still remains to be studied. The two men went down seven miles to the bottom of the Pacific Ocean inside a small steel ball to find out if there are any ocean currents(水流) or signs of life.

It was necessary to set out early, so that the ball would come to the surface in daylight, and be easily found by the mother ship which would be waiting for it. The divers began preparations early in the morning and soon afterwards, when all was ready, the steel ball disappeared under the surface of the water.

The divers felt as if they were going down steps as they passed through warm and cold layers (层) of water. In time the temperature dropped to the freezing point. They kept in touch with the mother ship by telephone telling how they felt. Then, at a depth of 3,000 feet, the telephone stopped working and they were quite cut off from the outside world. All went well until some four hours later at 30,000 feet, the men were frightened by a loud, cracking noise. Even the smallest hole in the ball would have meant instant death. Luckily, though, it was only one of the outer windows that had broken. Soon afterwards, the ball touched the soft ocean floor raising a big cloud of "dust" made up of small dead sea creatures. Here, powerful lights lit up the dark water and the men were surprised to see fish swimming just above them quite untroubled by the great water pressure. But they did not dare to leave the lights on for long, as the heat from them made the water boil. Quite unexpectedly, the telephone began working again and the faint but clear voices of the divers were heard on the mother ship seven miles away. After a stay of thirty minutes the men began their journey up, arriving three hours later, cold and wet through, but none was worse for their experience.

A. if there are water currents, and life in the great depths

B. if people can stand the severe cold in the great depths

French surgeons have performed what they said on Wednesday was the world's first partial face transplant— giving a new nose, chin and lips to a woman attacked by a dog.

Specialists from two French hospitals carried out the operation on a 38-year-old woman on Sunday in the northern city of Amiens by taking the face from a brain-dead woman, who had hanged herself just hours before the operation. Her family agreed on the operation.

“The patient is in an excellent state and the transplant looks normal,” the hospitals said in a brief statement after waiting three days to announce the pioneering surgery.

The woman had been left without a nose and lips after the dog attacked her last May, and was unable to talk or chew properly. Such injuries are “extremely difficult, if not impossible” to repair using normal surgical techniques, the statement said.

The statement did not say what the woman would look like when she had fully recovered, but medical experts said she was unlikely to resemble the woman who had been the source of her new face.

The operation was led by Jean-Michel Dubernard, a specialist from a hospital in Lyon who has also carried out hand transplants.

Skin transplants have long been used to treat burns and other injuries, but operations around the mouth and nose have been considered very difficult because of the area's high sensitivity to foreign tissue.

Teams in France, the United States and Britain had been developing techniques to make face transplants a reality.

There was a short-term risk for the patient if blood vessels became blocked, a medium-term danger of her body rejecting the new skin and a long-term possibility that the drugs used could cause cancers.

Experts say that although such medical advances should be celebrated, the transplant had thrown up moral(道德的)and ethical(伦理的) issues. Little is known about the psychological effect of the transplant.

1.The best title for the passage would be ________.

A. First Face Transplant Opens Debate

B. French Woman has First Partial Face Transplant

C. A Complete Face Transplant of a French Woman

D. Risks and Ethical Problems of a Face Transplant

2.Which of the following is NOT one of the risks of the operation?

A. Heart damage.

B. Organ rejection

C. Block of blood vessels.

D. Side effect of the drugs.

3.What can we learn about the operation?

A. There has arisen a debate about the operation.

B. The woman had used the dead woman' s whole face.

C. The woman will suffer from psychological damage soon.

D. Such transplants have been performed by doctors.

When I was 12, all I wanted was a signet (图章) ring. They were the "in" thing and it seemed every girl except me had one. On my 13th birthday, my Mum gave me a signet ring with my initials(姓名首字母) carved into it. I was in heaven.

What made it even more special was that it was about the only thing that wasn't being "replaced". We'd been burnt out in fires that swept through our area earlier that year and had lost everything—so most of the " new" stuff (东西) we got was really just to replace what we'd lost. But not my ring. My ring was new.

Then, only one month later, I lost it. I took it off before bed and it was missing in the morning. I was sad and searched everywhere for it. But it seemed to have disappeared. Eventually, I gave up and stopped looking for it. And two years later, we sold the house and moved away.

Years passed, and a couple of moves later, I was visiting my parents' when Mum told me that she had something for me. It wasn't my birthday, nor was it Easter or Christmas or any other gift-giving occasion. Mum noticed my questioning look. " You'll recognize this one," she said, smiling.

Then she handed me a small ring box. I took it from her and opened it to find my beautiful signet ring inside. The family who had bought our house 13 years earlier had recently decided to do some redecorations, which included replacing the carpets. When they pulled the carpet up in my old bedroom, they found the ring. As it had my initials carved into it, they realized who owned the ring. They'd had it professionally cleaned up by a jeweler before sending it to my mother. And it still fits me.

1.When she got the ring back, the writer was about _____.

A.13 years old B.15 years old

C.26 years old D.28 years old

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

A.The writer's family moved several times.

B.The writer never stopped looking for her ring.

C.The writer's ring was cleaned up by the new house owner.

D.The writer lost her ring in the morning when she took it off.

3.What would be the best title for the passage?

A.My New Ring B.Lost and Found

C.Lost and Replaced D.An Expensive Ring

Go, known as Weiqi in China and Baduk in South Korea, was viewed as the last game where humans can defeat machines. Lee Se-dol, one of the greatest Go players, has won 18 world championships for 21 years of his professional career. AlphaGo, a computer program developed by Google's DeepMind, beat the European Go champion, an achievement that was not expected for years in October, 2015.

The match between Lee and AlphaGo was seen as a representative game between humans and Artificial Intelligence (AI). The match of the century drew great attention from news organizations, Go fans and the general public across the world as well as in South Korea.

Go originated from China more than 2,500 years ago. It involves two players who take turns putting markers on a net-shaped board to gain more areas on it. One can occupy the markers of the rival (对手) by surrounding the pieces of the other. Go is considered to be a lot more complex than chess where artificial intelligence scored its most famous victory to date when IBM’s Deep Blue beat grandmaster Gary Kasparov in 1997.

But experts say Go presents an entirely different challenge because of the game’s incomputable number of move options. In other words, the computer must be capable of human-like "intuition" (直觉) to win.

"I was very surprised because I did not think that I would lose the game," said Mr. Lee. He said AlphaGo’s early strategy was “excellent” and that he was shocked by one unconventional move it had made that a human never would have played, which he believed directly resulted in his loss.

AlphaGo is proud of a deep learning capability to learn for itself and discover new strategies by playing games against itself and adjusting neural networks (神经网络) based on a trial-and-error process known as reinforcement (强化) learning.

In spite of his loss, he did not regret accepting the challenge. "I had a lot of fun playing Go and I’m looking forward to the future games,” he said after AlphaGo won 3-0 in a five-game match.

“Playing against a machine is very different from an actual human player. Normally, you can sense your rival’s breathing, their energy. And lots of times you make decisions which depend on the physical reactions of the person you’re playing against. With a machine, you can’t do that”, Lee said.

D. Lee Se-dol was convinced he would finally win the match before the series started.

3.What did Lee think was the cause of his loss?

A. AlphaGo had an excellent strategy and unconventional moves.

B. He couldn’t sense AlphaGo’s breathing and energy in the games.

C. He made decisions depending on the rival’s physical reactions.

D. The designer of AlphaGo was a talent who couldn’t be defeated.

Renaissance is a French word. It means “rebirth”. It’s a strange name for a period of history. What was exactly “ reborn” during the Renaissance?

To answer this question, we need to look back at the time of the Roman Empire. At this time Roman artists, scientists and writers influenced by Greek ideas were the world’s most advanced. They had become skilled observers of the natural world around them, and had become experts in studying animals, plants, the human body or the stars and planets. They wrote down their ideas about what they saw, and based their theories about the world on their observations.

During the fourth and fifth centuries the Roman Empire slowly broke down. Many of the Romans’ art and sculptures were destroyed and some manuscripts(原稿)were lost as well. But most importantly, some of the ancient attitudes were lost. A questioning approach to the world was replaced by an unquestioning one.

Why did this happen? One reason was to do with the influence of the Christian Church. Through the thousand years following the fall of the Roman Empire, the Church controlled many aspects of life including education and learning. The Church ran all the universities and thought that the aim of a university should be to teach old ideas more clearly, not to introduce new ones. The scholars in the universities were expected to study God and heaven from the Bible and ancient books, rather than the world around them.

Take medicine for example. The main textbook for doctors had been written by a Greek doctor called Galen more than a thousand years earlier. But when Roger Bacon, a thirteenth-century priest(牧师), said that a new approach to medicine was needed --- doctors should do their own original research instead of reading writers from the past such as Galen-the Church put him in prison.

By the time of the fourteenth century, however, some parts of the Christian Church were becoming less strict about their ideas and there was a new state of mind among artists, doctors and scientist. People wanted to find out more about the world by studying it. This attitude of investigation had been common in classical scholars, and it was ‘reborn’ during the Renaissance.

1.We know from the text that scientists at the time of the Roman Empire believed in_______.

A. their companions’ observations

B. what they saw with their own eyes

C. what they learned from the Greeks

D. the most advanced theories at that time

2.We can infer that students in the Church controlled universities might_________.

A. have good memories

B. change their beliefs

C. be lacking in creativity

D. be interested in astronomy

3.Roger Bacon was put in prison because he_________.

A. gave up being a priest

B. showed no respect for Galen

C. did some research secretly

D. challenged the Church

4.The text probably comes from a book about_________.

A. medicine B. education C. religion D. history
