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 (對(duì)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" (直覺(jué)) 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 (神經(jīng)網(wǎng)絡(luò)) based on a trial-and-error process known as reinforcement (強(qiáng)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.

1. Where can we most probably read this text?

A. In a personal diary

B. In a science magazine

C. In a science fiction

D. In a travel guide

2. Which of the following is TRUE?

A. Only people in South Korea pay attention to the match between Lee and AlphaGo.

B. Artificial intelligence rewrote the history as AlphaGo beat Gary Kasparov in 1997.

C. AlphaGo’s early strategy was to play by regular moves the same as human beings.

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.

4.This article is mainly about _____.

A. The differences between playing chess and Go

B. The difficulties Lee met in the match with AlphaGo

C. The introduction of a match between Lee and AlphaGo

D. The development of the Artificial Intelligence (AI)

We may not be aware of it, but ordinary family homes in the U.S. and the rest of the world are not energy-efficient.

Most of their energy goes to heating and cooling, and a lot of it is wasted, as warm air and cool air escape through fireplace chimneys and thin or poorly fitting windows and doors. A passive house loses almost none."Imagine a thermos(保溫瓶),"said housing developer Brendan O’Neill."You have insulation(隔絕) everywhere, and it’s basically completely sealed. And so the idea is to build a house like a thermos. So the windows are sealed. There’s insulation completely surrounding the building. We make it as sealed as possible."

A 147-square-meter passive house, presented by O’Neill Development Corp. as a demonstration unit just outside Washington, was brought to the site in two boxes. "Once it’s set and put together, it takes about four weeks to complete the outside construction, to put down carpets," O’Neill said. "If everything is set in place, you put a house like this together in about four months.”The total cost of building it was $325,000, or about 17 percent more than constructing an ordinary house. But its utility(公用事業(yè)) bill is only around $20 monthly, or one-tenth the amount for the average house of the same size.

While passive houses have been around for a long time, the idea has never taken root in the U.S. There was no driving force to push it.

However, David Peabody, an architect who designs passive houses said, "I think climate change is now becoming a larger issue. And I think building standards are catching on to that. So people are becoming more aware of energy."Peabody said the cost of building passive houses could come down."What really makes sense for truly affordable housing," he said, "is to build multi-storey buildings."

1.Why aren’t ordinary family homes energy-efficient?

A. Building them wastes much energy.

B. Their energy mainly goes to heating and cooling.

C. Their sealing performance is poor.

D. They have no insulation around at all.

2.What is the feature of a passive house?

A. There’re no windows or chimneys.

B. There’s little space to place furniture.

C. Its building cost is relatively high.

D. It takes about four weeks to build one.

3.What’s David Peabody’s attitude to the future of the passive house?

A. Cautious.B. Optimistic.C. Skeptical.D. Concerned.

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 (層) 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.

1.The purpose of the divers' journey to the deepest point on the earth was to find _______.

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

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

C. if there are steps in the great depths

D. if the telephone works well in the great depths

2.The divers set out early in the morning so that .

A. they could avoid the cold at night

B. they could see at the bottom of the ocean

C. they could return to the surface during the day

D. they could stay long at the bottom

3.As the divers went down to the ocean floor, the telephone .

A. kept working all the time

B. stopped working at a depth of 3,000 feet and began working again when they returned to the same depth

C. stopped working at a depth of 3,000 feet and began working again at 30,000 feet

D. stopped working at a depth of 3,000 feet and began working again after they reached the bottom

4.On the ocean floor, the divers found that .

A. there was no life but some small dead sea creatures

B. fish were swimming as freely as they do near the surface

C. fish were not swimming freely in the dark water

D. fish were not swimming freely under the high water pressure

Apart from my mother, I’ve been very lucky to having had two teachers who have been fundamental influences in my life. The first was my first piano teacher. She really got me interesting in the piano and made a huge impression in me at a very early age. She helped me to learn the basic techniques and develop understanding of the instrument. Then, when I was 16, I start studying with my second inspirational teachers. He made me much more confident and encouraged me to enter for competitions even when I felt certain and unconfident about doing this. He had enormous faith in us, and it was this, more than anything else, which inspired me to make music my career.
