The Internet has opened up a whole new online world for us to meet, chat and go where we've never been before.

    But just as in face to face communication, there are some rules of behavior that should be followed when on line. {#blank#}1{#/blank#} Imagine how you'd feel if you were in the other person's shoes.

    For anything you're about to send: ask yourself, “Would I say this to the person's face? If the answer is no, rewrite and reread. {#blank#}2{#/blank#}

    If someone in the chat room is rude to you, your instinct (本能 ) is to fire back in the same manner. But try not to do so. {#blank#}3{#/blank#} If it was caused by a disagreement with another member, try to fix the situation by politely discussing it. Remember to respect opinions of others in the chat room.

    {#blank#}4{#/blank#} Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate. When someone makes a mistake, whether it's a stupid question or an unnecessarily long answer, be kind about it. If it is a small mistake, you may not need to say anything. Having good manners yourself doesn't give you license to correct everyone else. {#blank#}5{#/blank#} At the same time, if you find you are wrong, be sure to correct yourself and apologize to those you have offended.

    Gabby Douglas stood beneath the Rio Olympic Arena, still in her Team USA leotard, trying hard to understand how she had become the most unpatriotic athlete in Rio. Tears filled in her eyes. She tried hard to talk but no words came out. Her pauses were long and uncomfortable.

    “I've been trying to stay off the Internet because there's so much negativity,” she said. The attacks against her have been everywhere these last few days. The bullies blamed her for not putting her hand over her heart while the US national song played. Besides, some other people attacked her for not jumping up and cheering hard enough for team-mates at the all-around final. All of this prompted her mother, Natalie Hawkins, to tell Reuters this weekend, that Douglas is “heartbroken”.

    It showed on Sunday, in Douglas's final performance of this Olympics and maybe in the Games ever. Douglas finished sixth in the uneven bars, far from the medal stand she owned four years ago in London, and shook her head, confused. What had she done wrong? Nothing made sense.

    “I mean, you do [Olympics] for your country, and you do it for yourself, how have I offended them? What have I done? I was standing in respect for USA. I'm coming out there representing them to the best of my abilities, so how would I be in disrespect?

    Do you often lose things? Don't worry. Now a new tool, which can be connected to any object you might lose, may be the way to solve your problem. The Tile, a small square linked up to your iphone or ipad by means of Bluetooth, lets you see how close you are to your missing item, within a 50-to-150-foot range (范围). If the item goes out of your phone's 150-foot range, it can still be found on other smart phones with the same app.

    When you drive the app on your phone, it shows you, with green bars that increase or decrease, how close or far away you are from the Tile. You can also program it to make a sound when you get close to the Tile. And you can link up your phone with up to ten Tiles. And if your lost object — a dog, for example, or a stolen bike — go out of your own phone's 150-foot Bluetooth range, you can set it as a “lost item”. If any of the phones with the Tile app comes within range of your lost item, a message will be sent to your phone, telling you its position. The Tile app also has the function to remember where it last saw your Tile, so that you can easily find where you left it.

    Since the Tiles use Bluetooth rather than GPS, they are never out of battery or needn't to be charged, and they work for one year before needing to be replaced. And the app works with all generations of iPhones and iPads.

    Many experts say that Billy Wilder changed the history of American movies. He is often called the best movie maker Hollywood has ever had, known for making movies that offered sharp social comment.

    Between the 1930s and the 1980s, Billy Wilder made almost fifty movies. During that time he received more than twenty nominations from the Academy of Motion Picture Arts and Sciences. He won six of the Oscar awards. His movies have been seen by people around the world, like “Sunset Boulevard”, “Some Like It Hot”, “The Lost Weekend”, “The Apartment”, and “The Seven Year Itch”.

    Samuel Wilder was born in 1906 in the former Austro-Hungarian Empire. His mother had enjoyed spending several years in the United States when she was young. So she called him Billy because she thought it sounded American. Billy Wilder started law school in Vienna, Austria. Then he decided not to become a lawyer. Instead, he began reporting for a Vienna newspaper. By the 1920s, he was writing movies in Germany.

    However, the Nazis had risen to power in the nation. Wilder was Jewish, and he recognized that he had no future in Nazi Germany. In 1933, he went to Paris. There he directed a movie for the first time. It was called “The Bad Seed”. Then he received word that producers in the United States had accepted one of his scripts. Billy Wilder left Europe for America.

    Billy Wilder had only eleven dollars when he arrived to settle in the United States in 1934. He decided to live in the center of American movie making, Hollywood, California. Then he formed a writing team with Charles Brackett. The two writers created many successful films together. Wilder always praised this man as a friend and teacher whose humor and expert direction greatly influenced his work.

    In his love stories, Billy Wilder did not follow the Hollywood tradition of sweet boy-meets-girl situations. He had an unusual way of showing relations between men and women. Wilder died in March, 2002. A current Hollywood producer said: “Billy Wilder made movies that people will never forget.”

    Increasingly, over the past ten years, people-especially young people have become aware of the need to change their eating habits, because much of the food they eat, particularly processed food, is not good for the health. Consequently, there has been a growing interest in natural foods: foods which do not contain chemical additives and which have not been affected by chemical fertilizers（化肥）widely used in farming today.

    Natural foods, for example, are vegetables, fruit and grain which have been grown in soil that is rich in organic matter. In simple terms, this means that the soil has been nourished by unused vegetable matter, which provides it with essential vitamins and minerals. This in itself is a natural process compared with the use of chemicals and fertilizers, the main purpose of which is to increase the amount but not the quality of foods grown in commercial farming areas.

    Natural foods also include animals which have been allowed to feed and move freely in healthy pastures（生活状况）. Compare this with what happens in the mass production of poultry（家禽）: there are battery farms, for example, where thousands of chickens live crowded together in one building and are fed on food which is little than rubbish. Chickens kept in this way are not only tasteless as food; they also produce eggs which lack important vitamins.

    There are other aspects of healthy eating which are now receiving increasing attention from experts in diet. Take, for example, the question of sugar. This is actually a nonessential food! It is not that sugar is harmful in itself. But it does seem to be additive: the quantity we use has grown steadily and in Britain today each person consumes an average of 200 pounds a year! Yet all it does is provide us with energy, in the form of calories. There are no vitamins in it, no minerals and no fibre.
