    Let us all raise a glass to AlphaGo and the advance of artificial intelligence. AlphaGo, DeepMind's Go-playing AI, just defeated the best Go-playing human, Lee Sedol. But as we drink to its success, we should also begin trying to understand what it means for the future.

    The number of possible moves in a game of Go is so huge that in order to win against a player like Lee. AlphaGo was designed to adopt a human—like style of gameplay by using a relatively recent development--deep learning. Deep learning uses large data sets," machine learning" algorithms (计算程序) and deep neural networks to teach the AI how to perform a particular set of tasks. Rather than programming complex Go rules and strategies into AlphaGo DeepMind designers taught AlphaGo to play the game by feeding it data based on typical Go moves. Then, AlphaGo played against itself, tirelessly learning from its own mistakes and improving its gameplay over time. The results speak for themselves.

    Deep learning represents a shift in the relationship humans have with their technological creations. It results in AI that displays surprising and unpredictable behaviour. Commenting after his first loss, Lee described being shocked by an unconventional move he claimed no human would ever have made. Demis Hassabis, one of DeepMind's founders, echoed this comment:"We're very pleased that AlphaGo played some quite surprising and beautiful moves."

    Unpredictability and surprises are—or can be—a good thing. They can indicate that a system is working well, perhaps better than the humans that came before it. Such is the case with AlphaGo. However, unpredictability also indicates a loss of human control. That Hassabis is surprised at his creation's behaviour suggests a lack of control in the design. And though some loss of control might be fine in the context of a game such as Go, it raises urgent questions elsewhere.

    How much and what kind of control should we give up to AI machines? How should we design appropriate human control into AI that requires us to give up some of that very control? Is there some AI that we should just not develop if it means any loss of human control? How much of a say should corporations, governments, experts or citizens have in these matters? These important questions, and many others like them, have emerged in response, but remain unanswered. They require human, not human - like, solutions.

    So as we drink to the milestone in AI, let's also drink to the understanding that the time to answer deeply human questions about deep learning and AI is now.

(1)、What contributes most to the unconventional move of AlphaGo in the game?
A、The capability of self-improvement. B、The constant input of large data sets. C、The installation of deep neutral networks. D、The knowledge of Go rules and strategies.
(2)、A potential danger of Al is _____.
A、the loss of human control B、the friendly relationship C、the fierce competition D、the lack of challenge
(3)、How should we deal with the unpredictability of AI?
A、We should stop AI machines from developing even further. B、We should call on the government to solve these problems for us. C、We should rely on ourselves and come up with effective solutions. D、We should invent even more intelligent machines to solve everything.
(4)、What's the author's attitude towards this remarkable advance in AI?
A、Supportive. B、Optimistic. C、Doubtful. D、Cautious.

    The Women's Institute is urging supermarkets to do more to help consumers reduce their home food waste, after a survey of its own membership showed widespread confusion about “best before” and “use by” labeling(标签) on packaging.

    Its new analysis of products on supermarket shelves found that “once-opened” instructions were often contradictory and often failed to make clear whether they were a guide to food safety or quality. Only 45% of 5,000 WI members surveyed understood that best-before dates were a sign of food quality, while 26% did not understand that the more important use-by dates were a decisive guide to food safety.

    In its report on food waste, the WI said supermarkets were “potentially contributing to home food waste by leading customers to buy more food than they need, and giving conflicting and confusing on-pack information that leaves customers unsure about how long a product remains safe to eat in the home setting”. The 42-page report is part of the WI's ongoing campaign to reduce food waste. To underline the point about conflicting information, it cites(引用) a can of Sainsbury's own-brand sweetcorn advising consumers to eat it within one day of opening, while a similar tin from Waitrose gave consumers two days to finish it. Green Giant sweetcorn, however, has no specified date for eating once opened.

    Marylyn Haines Evans, chair of the Women's Institute's public affairs said: “WI members are some of the more informed members of society about food and cookery, but they are still confused about food labelling and 'once-opened' information. So we would like supermarkets to extend the amount of time that consumers have to use a product in their homes by making all of their once-opened instructions on product packaging consistent, and completely remove once-opened instructions on products where food safety is not an issue.”

    A new report shows that there are just 7,100 cheetahs now left in the wild. Cheetahs are in trouble now.

    According to the study, more than half of the world's surviving cheetahs live in one zone that covers six countries in southern Africa. Cheetahs in Asia have nearly died out. It's thought that only fewer than 50 cheetahs live in Iran.

    The cheetah runs across lands far outside protected areas. Some 77% of their habitat falls outside these protected areas. As a result, the cheetah struggles because these lands are increasingly being developed by farmers and the cheetah's food is decreasing because of human hunting.

    In Zimbabwe, the cheetah population has fallen from around 1,200 to just 170 in 16 years, with the main cause being major changes in land ownership.

    Researchers say that the threats cheetahs are facing have gone unnoticed for far too long. “Given the nature of the cheetah, it has been difficult to gather information on them,” said Dr Sarah Durant, the report's lead author. “Our findings show that the large space requirements for cheetahs and various threats faced by them in the wild mean that they are likely to be in danger of dying out.”

    Another big concern about cheetahs has been the illegal trafficking (非法交易) of young cheetahs. The young cats can fetch up to $10,000 on the black market. Some 1,200 young cheetahs are known to have been trafficked out of Africa over the past 10 years but around 85% of them died during the journey.

    If the cheetahs are to survive, then immediate efforts must be made.

    I always wondered how people would react if I tried to approach a total stranger for help in a busy place like a street corner or in a noisy mall. I have always hurried past a stranger who tried to catch my attention in a busy place or when I am rushing around.

    Yesterday, I was in a busy shopping mall buying a large piece of luggage because I just had the time to do it after many days of planning. After the purchase in one of the large shops, I picked up my phone from my pocket to call my driver waiting in the parking lot but my phone was dead.

    I then requested the shop assistant who had just sold me the luggage to ring the number of my driver for me and she replied that it was the shop policy that they cannot use mobile phones while working in the shop.

    I got out of the shop onto the busy street in front and approached a young mother with her two kids to make a request. As soon as I said “Excuse me, madam”, she grabbed both her kids and ran. I felt like a kidnapper.

    I stood there, wondering how many times I had reacted to strangers like the young mum. I stood there in the busy street with people rushing by, looking at their faces to see if there was a sign of kindness on their faces.

    I saw a man pretty shabbily dressed. He seemed to have noticed me and I just stopped him expecting him to rush past. My request escaped the lips. He immediately called the number of my driver and waited till my car came to be sure I was picked up, and he turned around before I could thank him adequately and was gone. I was surprised by his kindness and hope I will do likewise to strangers who try to catch my attention from now on.

    Valerie Jarrett, 58, is serving as a top adviser to President Obama and has been close to the first family since the early 1990s. Joe Heim from WashingtonPost had an interview with her.

    Joe Heim: What do you think of a reporter who interviews you for 25 minutes, then later finds out his recorder stopped working and asks you to do the interview again?

    Valerie Jarrett: That he's human. Everybody could make mistakes.

    Joe Heim: You're considered the president's closest adviser. What do you think the role of an adviser is?

    Valerie Jarrett: I think so as that the president's management style is very effective (有效的), all of his advisers should speak openly about their advice.

    Joe Heim: What misunderstandings are there of you?

    Valerie Jarrett: A little-known fact is that I started my life very shy and remained very shy well into adulthood. Painfully shy, I would call it. And I often share this, particularly with young people, because it's something I really had to work hard to overcome. And for all the shy people out there I say, you, too, can overcome it. But it took a lot of hard work on my part, and I discovered along the way that just because you're nervous and you have butterflies in your stomach doesn't mean that it has to show. My point in sharing it with you is that part of life is pushing yourself outside of your comfort zone (舒适区). And if you're going to grow, you have to learn how to take on new challenges that you might not be good at.

    Joe Heim: Will you stay until the end of his term?

    Valerie Jarrett: I serve at the pleasure of the president. If he wants me to stay, I will.

    In Scotland, 600,000 tonnes of food are thrown away every year. This amount of food, which could as feed about 1.2 billion poor people, is almost a third of household (家庭) waste. And food waste isn't just a big problem in Scotland.

    Money time, and resources (资源) are often wasted by throwing away good food. It also causes very harmful greenhouse gas, which is perilous to the planet.

    In the production stage, some foods do not enter the food chain for many reasons. Supermarkets usually care about the quality of food from farms. They often refuse strange-looking and unusually sized produce. However, they seem to forget that it is almost impossible to grow the perfect produce. Food waste at the consumption (消费) stage includes food going out of date and leftovers (剩饭) because of too much food. In households, even mostly fresh fruit and vegetables are thrown away.

    In order to reduce food waste, here is what we can do:

    Understanding the terms “use by” and “best before” dates. “Use by” dates are there for your safety. It is dangerous to eat food after the use-by date and doing so risks your health. “Best before” dates tell you how long the food will be at its best quality. Once the food passes the date, it isn't necessarily bad, but you should still check, just to be sure.

    Every time you go shopping and you bring back new food, put them at the back of your fridge and bring the food that will expire (到期) soon closer to the front. That way, you know what needs to be eaten first.

    If you have any food that will expire soon, give it to charity if you aren't going to eat it. They will really appreciate the food you have given.

    English is a very interesting language. It has borrowed words from many other languages. Immigrants (移民) coming into the United States have contributed many words to the language, which have kept their original pronunciation. "Coolie" and "kowtow" were taken from the Chinese language, "kamikaze" from the Japanese, "shampoo" from India, "blitz" from German, "amigo" and "Los Angeles" from Spanish and so on.

    Many students have studied English for years, some as many as eight. However, some students still have difficulty in speaking fluent English. Some know many words, but are unable to discern them when native speakers use them. In our oral English classes we will focus on speaking and listening to native English speakers. For this reason, because we are trying to train your ears to hear English and your mouths to speak intelligible (易理解的) English, we will have a rule that ONLY ENGLISH will be spoken in our English classes. Anyone speaking Chinese in class will be required to pay a fine (罚款) in order to encourage the speaking and understanding of English. If teachers enter a classroom and discover that anyone is speaking Chinese, they will require everyone in the room to pay the fine. It is everyone's job to enforce the English­Only rule. It is for your benefit. It is because we want to accustom (使习惯于) your ears to hearing English.

    Other subjects may be learned only from books but the only way to learn a foreign language is to SPEAK IT! Students are often nervous about speaking in class at first but we hope to make the classes fun, so you will forget your nervousness and learn to speak out. Enjoy your classes.
