In March, 2016, the pride of humankind was crushed by a computer. Google's AlphaGo defeated the South Korean Go master Lee Sedol four games to one, as the world looked on with shock and awe. Artificial intelligence had suddenly reached a new and unexpected height.
But as smart as AlphaGo is, it's no longer the best Go "player" in the world. Google's artificial intelligence group, DeepMind, has created the next generation of its Go-playing program, called AlphaGo Zero. The new AI program is unique in the way it learned to play Go. Instead of learning from thousands of human matches, as its predecessor (前任) did, AlphaGo Zero mastered Go in just two days without any human knowledge of the game and defeated AlphaGo by day three, reported The Guardian. It then went on to defeat AlphaGo 100 games to zero.
To learn how to play Go, AlphaGo Zero played millions of matches against itself using only the basic rules of the game to rapidly create its own knowledge of it. Like the previous version, it used "reinforcement (增强) learning to become its own teacher," according to DeepMind's website.
"It's more powerful than previous approaches," David Silver, AlphaGo's lead researcher, told The Guardian, "because by not using human data, or human expertise in any fashion, we've removed the constraints of human knowledge and it is able to create knowledge itself."
AlphaGo Zero's approach to self-learning is a significant advancement in AI that could be applied to help solve some of the world's biggest problems, according to a recent research report published in the journal Nature. For example, DeepMind co-founder Demis Hassabis argues that AlphaGo Zero could probably find cures for a number of serious diseases within weeks, according to The Telegraph. Indeed, the AI is now being used to study protein folding, which is connected to diseases such as Parkinson's and Alzheimer's.
So now that AI has gone beyond the bounds of human knowledge, perhaps the question is not about what AI can learn from humans, but what humans can learn from AI. We can only wait and see.
1.What can we learn from the first two paragraphs?
A.AlphaGo defeated Lee Sedol five games to zero.
B.AlphaGo Zero defeated AlphaGo within one day.
C.AlphaGo Zero has become the new best Go player.
D.AlphaGo Zero is the first program to defeat a human at Go.
2.What does the underlined word "constraints" in the fourth paragraph probably mean?
A.advantages B.disadvantages
C.restrictions D.regulations
3.What's the possible application of AI in the future according to the article?
A.Treating diseases. B.Making new Go rules.
C.Solving math problems. D.Creating new proteins.

As Alice and Mike watched their son Allan graduate from Cambridge University last month, they thought back to the moment he was born.
“I’m so sorry your baby is blind,” a neighbor had said. Even though Allan’s family were middle class and they lived a comfortable life, as a blind child, Allan Hennessy’s future was poor.
The local hospitals could not offer Allan hope of giving him sight because there weren’t enough eye specialists. But when Allan was 6 months old, an opportunity came and Allan’s father seized it. “My dad sold his car, belongings and some of his land to pay for my treatment. We left our home country with very little.”
The opportunity was an operation in London which restored the sight in Allan’s left eye. “My mom remembers the first time I looked at her: the first time we made eye contact. She burst into tears. Since then, I’ve just been rocking on with the little sight I have,” he explained.
For Allan, life as an immigrant was challenging. When he was accepted into Cambridge University, Allan realized there were so many peers at Cambridge.
“I felt visibly different,” he said. When you’re a half-blind guy climbing the greasy pole, everyone can see that and they judge you, even though they are climbing it too.”
But after spending three years at Fitzwilliam College, Allan said it was transformative（改造作用的）. “I met the most amazing people from all over the world.” What would his life be like if he had stayed in his home country? “I wouldn’t have a Cambridge law degree; I wouldn’t even be sighted. My family there have faced terrible events. Perhaps I wouldn’t be alive.”
After graduating this summer, Allan is taking up a scholarship at law school.
“If you’ve got a first-class law degree from Cambridge University, that should set you up for life,” he said. “But when you’re a half-blind immigrant living in Britain today, there is so much more I have to do. The journey has only just begun.”
1.When Allan was born, __________.
A.a local doctor offered to help with his eye problems
B.he lived in a poor area
C.his family was ready to move to London
D.he couldn’t see anything
2.The underlined word “ it” in Paragraph 3 refers to __________.
A.the selling of Mike’s belongings
B.an operation to cure Allan’s eyes
C.the comfortable life in London
D.the bright future of the family
3.How was Allan’s life in Cambridge?
A.He was helped by many of his peers.
B.He worked hard to keep up with his peers.
C.He was bullied by others for many years.
D.He found it challenging but life-changing.
4.We can infer from the last paragraph that Allan__________.
A.won’t stop challenging himself in the future
B.is proud of his achievements in college
C.is determined to help other half-blind students
D.is unsatisfied with his life as an immigrant

A small dairy（乳制品）farm that floats on waterways is being tested in the Netherlands as a way to bring animal products closer to the cities and save space.
Dutch businesswoman Minke Van Wingerden looks proudly at her 32 cows at an automated milking station on an unusual farm: a platform located on one of the waterways in Rotterdam port. She is one of the developers of the “Floating Farm,” testing whether dairy farming like this is feasible in the heart of one of the world’s most urban, industrial areas.
“This idea started in 2012. My partner Peter was involved in a project in New York and then Hurricane Sandy hit New York very badly, so it was flooded and after two days there was no fresh food on the shelves anymore,” she said, “So then we realized, ‘Why not produce fresh food on the water close to the city?’, and that’s where the idea came up.”
The cows can rest on the upper level of the structure. Milk and waste processing facilities are located on the lower deck, as well as the visitors’ entrance and store. The top level of the structure is used to collect rainwater. Power for the farm comes from a solar panel floating nearby.
“The amount of arable（可耕的）land is decreasing and the world population is growing. So how can we produce enough healthy food in the future?” Ms. Van Wingerden said. “Why not use water to produce fresh healthy food near to the consumers?”
The whole farm is equipped with the latest dairy tech such as an automated feeding system, waste-moving robots, self-serve cleaning stations, and the smartphone app. It sells some bottles of raw milk on-site to visitors, while the rest is turned into milk. It is sold to customers nearby via an online grocery, Picnic, known for its small, electric delivery trucks.
1.Which of the following can replace the underlined word “feasible” in paragraph 2?
A.Disgusting. B.Practical.
C.Enjoyable. D.Flexible.
2.What do we know about the platform?
A.It was once flooded by a hurricane.
B.It is powered by the waterways nearby.
C.It was originally invented in New York.
D.It has three floors for different functions.
3.We can infer from the last paragraph that ________.
A.picnic deals mainly with dairy products
B.electric equipment is being tested on the farm
C.modern tech has been applied to farm management
D.visitors prefer bottles of raw milk to farm-made milk
4.What can be a suitable title for the text?
A.New Food Farm Solves Problems of the Public
B.“Floating Farm” Creates Local Dairy for Cities
C.Latest Invention Contributes to Food Shortages
D.Less Arable Land Threatens World Population

My parents visited me to help with a project I’d put off — cleaning the house. Now, Mom and Dad are— hmm, how should I put this? — cheap! So when I offered to pick up the cleaner, they said, “Never mind. We have everything we need right here in the house.”
Mom pushed past me and went straight for the white vinegar (醋). I watched her remove a dirty mark on the blanket with it. I thought it a bit strange, but less so than her smelling at my bookshelf. When one book caused her nose to blow, she walked it into the fridge.
“That’ll clear up that unpleasant smell for a while,” she said. I nodded in agreement, although I wasn’t sure. I thought only her husband would know. I found Dad in the yard adding vodka, and some dish soap into a spray bottle (喷雾瓶).
“I’m hunting weeds,” he said.
“A wine?”
“Yes, the wine does dry them up.”
How come? They must have lost their marbles! I thought as I walked back into the house, where Mom was cleaning my shoes with banana skins.
“Mom, what are you …” BAM! I slipped on a banana skin. “Ooh, my back ...”
“Don’t move! I’ll get the meat tenderizer (嫩化剂)!”
However, she first pulled off my shoe, grabbed a sock and disappeared into the kitchen. I tried to run for my life, but Mom was quicker. She returned with my sock filled with meat tenderizer and water, and rubbed it on my back.
Before I had a chance to call 911, something amazing happened—my back began to feel better! It was working.
Suddenly, I saw things anew. My shoes were clean. And though the blanket smelled like salad, the mark was gone. Inside the yard stood Dad, drinking his weed killer and admiring his handiwork.
1.The parents come to my house _________.
A.to do the cleaning
B.to cook a delicious meal
C.to prepare a gathering
D.to share a learning experience
2.What does the underlined sentence “They must have lost their marbles!” in the text mean?
A.They wasted time. B.They were clever.
C.They made wonders. D.They were crazy.
3.Which of the following can best describe the parents?
A.Foolish but reliable B.Generous and devoted
C.Mean but intelligent D.Caring and experienced
4.What can be a suitable title for the text?
A.Mom's Love B.Life Wisdom
C.A Sudden Visit D.Magic Cleaner

阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。
A quite funny thing happened to me last Friday. It was a fine day and I went to London to do some shopping. I had planned to get some Christmas presents. I also needed to find some books for my course at college as I am a student of Oxford.
That morning I caught an early train to London, so by early afternoon I could buy something that I wanted. Anyway, I'm not very fond of London, all the noise and traffic, and I made some arrangements for that evening. I took a taxi to Waterloo station. I couldn't really afford a taxi, but I wanted to catch the 3:30 p.m. train. Unfortunately, the taxi got stuck in a traffic jam, and by the time I got to the Waterloo station the train had just gone. Disappointedly, I had to wait an hour for the next one. While I was waiting, I bought myself an evening newspaper, The Standard, and wandered over to the station buffet (自助餐). At that time of the day it was nearly empty, and I bought a coffee and a packet of biscuits (饼干)—chocolate biscuits. I'm very fond of chocolate biscuits. I found that there were plenty of empty tables and I sat by one near the window, where I could cozily enjoy my beverage and biscuits. Then, I began doing the crossword. I always enjoy doing crossword puzzles.(填字游戏)
After a couple of minutes a man sat down just opposite me. It seemed that there was nothing special about him, except that he was very tall. In fact, judging from his clean dark suit and a fine briefcase, he looked pretty like a typical city businessman. I didn't say anything and I carried on with my crossword.
注意：
（1）所续写短文的词数应为150左右；
（2）至少用5个短文中标有下划线的关键词语；
（3）续写部分分为两段，每段的开头语已为你写好；

Paragraph 1:
Suddenly he reached across the table, opened my packet of biscuits, took one, and put it into his mouth.
_________________________________________________________
Paragraph 2:
After I took the last biscuit and glanced at(瞥一眼) the man, he was staring at me angrily.
