Instagram is a fast, beautiful and fun way to share your life with friends and family. Take a pictureor video, choose afilter to transform its look and feel. and then post to Instagram—it's that easy. You can even share to Facebook. Twitter andmore. It's a new way to see the world. So many photos of food are contained on Instagram—now a pop-up diner in London is taking advantage of this new trend by letting people settle the bill for their meals simply by uploading photos of their dishes to social networks.

    I always thought people's taking pictures of their food was kind of silly, but at this new pop-up restaurant in the UK, I'd probably do it too.“The Picture House”is the world's first pay-by-photo restaurant—you order, click a photo of the food, share on Instagram and eat for free!

    The restaurant belongs to frozen food giant(巨人) Birds Eye, who came up with the idea to cash in on people's addiction with photographing food and sharing the pictures online. They conducted a survey and found out that more than half of the British population regularly took pictures of their meals. So they realized it was a better way to advertise their new dining range.

    The pop-up diner was open in Soho, London for three days in May, and is now moving to other major UK cities. They serve two-course meals that customers don't have to pay for, if they photo and lnstagram it.

    The restaurant is a part of Birds Eye's“Food for Life”campaign, a new marketing project that aims at changing the way people look at frozen food.“Taking photos of food enables people to show off and to share their mealtime moments—from the everyday to the special.” said marketing director Margaret Jobling.

    The reaction to The Picture House has been great so far and the pay-by-picture concept has proven to be an effective way. Alternative payment methods are actually gaining popularity among a lot of businesses. Last year in a cafe in Germany customers pay by how much time they spend there, not by what they eat.

    According to sociologists(社会学家), every modern industrial society has some form of social stratification(阶层). Class, power and status are important in deciding people's rank in society.

    Class means a person's economic position in society. A commonly used classification is lower class, middle class and upper class. While sociologists disagree on how these terms should be exactly defined, they do describe societies like the United States quite well. One study shows that 53% of Americans belong to the lower class, 46% the middle class, and 1% the upper class. Interestingly, a surgeon earning $500,000 a year and a bus driver earning $50,000 a year both regard themselves as the middle class!

    Power refers to the amount of control a person has over other people. Obviously, people in positions of great power (such as governors) exercise(行使)big power, but people who take orders from others have less power. Power and class do not always go hand in hand, however. For example, the governor of a state has great power, but he or she may not belong to a corresponding (相应的)economic class. Generally, however, there is a relationship between power and class. To our knowledge, there aren't too many people who aren't millionaires in the U．S. Senate!

    Status is the honor or respect attached to a person's position in society. It can also be affected by power and class, but not necessarily so. For example, a university professor may have a high status but not belong to a high social class or have a lot of power over others.

    Many people believe that you lose the ability to learn new languages as you get older. Language experts, however, will tell you that you're never too old to learn a new language. As you get older, it can be more difficult to learn a new language, though.

    Children and adults learn new languages in different ways. For children, language is their life. They study for thousands of hours every year, because they need to learn languages to become part of their communities. Adults, on the other hand, are already part of a language community. Learning a new language means becoming part of another language community, and adults rarely get the chance to practice as much as young children do.

    Moreover, children learning a new language are expected to make mistakes. This gives them freedom when learning to be daring and confident. Adults, however, often feel stressed to be perfect when learning a new language. This can discourage many people and make it even harder to learn a new language.

    When young children learn a new language, they come to see various languages as a “normal” part of society. This mindset helps them to learn a new language without feeling like they're doing something unusual or “too hard”.

    So if you want to learn a new language, go for it! It's never too late to learn a new language. If you're older, it may take more work, but it can be done. If you're a young child, though, now is the time to step out and learn a new language!

    One day an old woman was traveling alone in the mountains. Suddenly she saw something shining in the stream. When she came close, she found it was a precious （珍贵的） stone. She put the stone into her bag and went on with her trip.

    The next day the old woman met a young man, who was also a traveler in the mountains. The young man looked very hungry, so the old woman opened her bag to share her food. The hungry traveler saw the precious stone and asked carefully, “The stone is beautiful. Would you like to give it to me?”

    “Sure. Why not?” the woman said, and handed the stone to him.

    The young man left happily with the stone. He knew it was worth enough to give him security for a lifetime. But a few days later he came back to return the stone to the woman.

    “I've been thinking,” he said. “I know how valuable the stone is, but I give it back and hope that you can give me something even more precious. Give me what you have within your bag.”

    The woman opened her bag. It was almost empty. She looked at the young man and smiled, “I have nothing special in my bag, but I do have something precious — the joy of giving!”

    The young man felt ashamed and left silently.

    An 80-year-old man was sitting on the sofa in his house along with his 45-year-old highly educated son.

    Suddenly a crow (乌鸦) perched on the tree near their window.

    The father asked his son, "What is this?"

    The son replied, "It is a crow."

    After a few minutes, the father asked his son the second time, "What is this?"

    The son said, "Father, I have just now told you. It is a crow!"

    After a little while, the old father again asked his son the third time, "What is this?"

    "It's a crow, a crow, a crow!" said the son loudly.

    A little after, the father again asked his son the fourth time, "What is this?" This time the son shouted at his father, "Why do you keep asking me the same question again and again? 'IT IS A CROW'. Are you not able to understand this?"

    A little later the father went to his room and came back with an old diary, which he had kept since his son was born. On opening a page, he asked his son to read that page. When the son read it, the following words were written in the diary:

    "Today my little son aged three was sitting with me on the sofa, when a crow was sitting on the window. My son asked me 23 times what it was, and I replied to him all 23 times that it was crow. I hugged him lovingly each time he asked me the same question again and again for 23 times. I did not at all feel annoyed; I rather felt affection for my innocent child."
