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(保温瓶),"said housing developer Brendan O’Neill."You have insulation(隔绝) 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(公用事业) 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.

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.
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 had a discussion on “overnight-fame” last week. Nowadays, many people were crazy about instant fame and wealthy. To be honest, it is not bad be famous or have a lot of money, but I don’t agree with the view which people rise to fame overnight. We all know “easy come, easy go”. Let’s take Li An as the example. Only after his hard work did he become successful. Or we can list more similar cases if need. What I do believe is that the process in which we try our best. It is we have experienced along the way to success that we treasure and enjoy mostly.
