John graduated from a key university and he was very good at his major. He wished to find a good job. One day, he went to a company to 1 for a job. He got the news in a newspaper. He did some research on this company. When he was 2, everything went well. The manager asked him some questions and he answered them 3. John was very satisfied with his performances and was very 4 that he could get the job. But at that moment, the manager's phone 5. He picked up the phone, listened and nodded. And then he turned around and said to John, “Sorry, I want to get some important 6 now. Please give me the book with the red 7 on that desk.” John looked around and found 3 books on the desk, so John went to the desk, took one book and handed it to him 8. Holding the book, the manager 9 the phone and said, “Sorry, we cannot give the job to you.” John was 10 and wondered why. The manager said, “There are three 11. First, when you came into the office room, I found that the third button on your shirt had been missing. Second, there are three books with red covers on that desk, but you didn't ask me which one I needed and you took one randomly（随机地）. Third, I was answering the call. You should 12to the desk to save time. These 13 showed you are not a careful person.”14, John didn't get the job.
We can learn a(n) 15 from John's experience. Some people don't 16the details in our life. But it is the details that 17. Not only should we value what we learn but also we should pay more attention to the details. Sometimes they can even 18 our success or failure. We should form the habit of being careful and learn to keep the 19 of quantity and quality. We should keep it in mind that 20 comes first, without which quantity is of no significance.
A living robot has been created out of frog skin cells. Xenobots, named after the frog species Xenopus laevis that the cells come from, were first described last year. Now the team behind the robots has improved their design and demonstrated new capabilities.
To create the xenobots, Michael Levin at Tufts University in Massachusetts and his colleagues obtained tissue from 24-hour-old frog embryos after very small physical operation. Where the previous version relied on the contraction of heart muscle cells to move them forward by pushing off surfaces, these new xenobots swim around faster. They also live between three and seven days longer than their previous generation, which only lasted about seven days, and have the ability to sense their surroundings to some extent, turning red when exposed to blue light.
"The fundamental finding here is that when you free skin cells from their normal context, and you give them a chance to build other things than what they normally build," says Levin. "To me, one of the most exciting things here is that they are plastic. This idea that even normal cells, not genetically modified, are in fact capable of building something completely different."
Because they are created from cells, the xenobots eventually break apart and are totally biodegradable, says team member Douglas Blackiston, also at Tufts University. He therefore hopes that they can be used for biomedical and environmental applications.
Previous attempts at creating living robots, such as a wirelessly controlled cockroach, have involved dealing with live animals, raising ethical concerns. Xenobots differ from these because they are made entirely of living cells. "The approach here is maybe ethically the least problematic because everything starts with cells. They have no neurons, so it's not an animal," says Auke ljspeert at the Swiss Federal Institute of Technology at Lausanne, who wasn't involved in the research. "It's really cells, so I find it maybe the cleanest way."

Roubaix, France
If you like France, Roubaix located in the north of France is just for you. The local authorities want it to be populated and attractive. You can buy a small house in the industrial district for just $1. The buyer is supposed to live in this house for 3 years.
Buffalo. USA
Buffalo offers whoever qualifies to buy a house for $1. All you need is to be a lawful citizen of the city and invest amount of money into its decoration. Doing this, the authorities are hoping to make the city beautiful again without spending money.
Liverpool, Great Britain
In Liverpool, most of houses were abandoned by the working class during the years of unemployment. The government is trying to sell the houses for just $1. If you want to buy such a house, it has to be your first deal on buying property (不动产).
Candela, Italy
If you still have any doubts about spending SI on a house, you should know: the government will pay you some money, if you move to Candela.

Janus, the Roman god, has two faces looking in opposite directions. So does artificial intelligence (AI). On one side are the positive changes, enabling people to achieve more, far more quickly, by using technology to improve their existing skills. Look the other way, though, and there are plenty of potential pitfalls.
Like Janus, technological change may also cause disruption(混乱), but AI is likely to have a bigger impact than anything since the appearance of computers, and its consequences could be far more disruptive.
In the years ahead, AI will raise three big questions for bosses and governments. One is the effect on jobs. Although CEOs publicly praise the broad benefits AI will bring, their main interest lies in cutting costs. One European bank asked Infosys to find a way of reducing the staff in its operations department from 50,000 to 500. The McKinsey Global Institute estimates that by 2030 up to 375m people, or 14% of the global workforce, could have their jobs replaced by AI.
A second important question is how to protect privacy as AI spreads. The internet has already made it possible to track people's digital behavior in minute detail. AI will offer even better tools for businesses to monitor consumers and employees, both online and in the physical world. Consumers are sometimes happy to go along with this if it results in personalised service or promotions. But AI is bound to bring invasion of privacy that is seen as unacceptable. For example, law-enforcement officials around the world will use AI to spot criminals, but may also monitor ordinary citizens.
The third question is about the effect of AI on competition in business. A technology company that achieves a major breakthrough in artificial intelligence could race ahead of rivals, put others out of business and lessen competition. This is unlikely to happen in the near future, but if it did it would be of great concern.
It is too early to tell whether the positive changes brought by AI will outweigh the risk. But it will put an end to traditional ways of doing things and start a new era for business and for the world at large.
When it comes to the benefit of volunteering, a lot of people think it’s all about the warm feeling after helping someone.__36____ As is known, Charity work requires a wide variety of people to do a wide variety of things for everything to work. It means that there are some surprising benefits for volunteers. For example, volunteering:
★ Teaches you new skills
From helping making websites to teaching immigrant kids your native language, or to arranging events for charity, volunteering can really be almost anything. It means that when you get involved in charity work, a lot of the time you will face challenges.__37____
★Can teach you what truly matters
It’s a great way to find new perspectives(视角）on life. When you've been at it for a while， you just might find yourself re-evaluating your advantages. __38___ One of my friends went from wanting to be a lawyer to discovering a true passion for teaching.
★ ___39___
Maybe it’s not so surprising, but what might surprise you is how genuine these friends are. Some of my long term friends are people I’ve met through volunteering. I’m not the kind of guy that makes friends purely for connections, but sometimes it’s very convenient to have a broad network.
Summed up in one line: Volunteering helps you grow._40____ You meet a very wide variety of people you don’t have a lot in common with. You learn to get along with people involved in many different walks in life. You learn to know what you are to do. So if you’ve ever considered volunteering, what are you waiting for?
A. Helps you make new friends.
B. Can help improve social skills
C. You might even decide on a completely new path to take in life.
D. As it turns out, that’s far from the only benefit.
E. Volunteering helps you look outside yourself and your problems.
F. Through overcoming the challenges, you learn completely new skills.
G. Not only as a person, but it helps you develop your skill set as well.
Do you ever feel like you’ve got a great idea, one that makes you feel incredibly inspired and want to change the world? 16 . We’ve all been there. And we’ll all be there again and again throughout life. So take a deep breath, and try these techniques:
1. Start small.
So often, we feel the need to take great leaps and bounds. Every day needs to
be filled with productivity. But we reach a point where we get overwhelmed by all the things we have to do. Break it down. 17 . Take a baby step. Once you get going, it will be harder to stop.
2. Do the thing you’re afraid of.
Often when we get overwhelmed, it’s because the task ahead is daunting(吓人的). There’s no easy way around it. The more we think about it, the more frightened we feel. 18 Most of the time, things are never as bad as we imagined them in our minds.
3. 19
The biggest misunderstanding is that we have to do everything on our own. But that’s simply not true. Success never comes without support. So reach out. Call a friend. Ask for advice. Your community will be more than happy to help, and you’ll feel better.
20 The harder you work for something you believe in, the better you will feel about it. And once you learn how to handle hitting a brick wall, it will get easier to deal with the next time around.
A. Ask for help.
B. Don’t give up.
C. No one wants to live with regrets.
D. No one can do everything all at once.
E. So stop thinking about it, and just do it.
F. Remember that if it’s not easy, it probably means it’s worth it.
G. But then once you start working on your idea, you start doubting yourself.
