Silence is unnatural to man.He begins life with a cry and ends it in stillness.In between he does all he can to make a noise in the world,and he fears silence more than anything else.Even his conversation is an attempt to prevent a fearful silence.If he is introduced to another person,and a number of pauses occur in the conversation,he regards himself as a failure,a worthless person,and is full of envy of the emptiest-headed chatterbox（喋喋不休的人）. He knows that ninety nine percent of human conversation means no more than the buzzing of a fly,but he is anxious to join in the buzz and to prove that he is a man and not a waxwork figure（蜡塑人像）.

    The aim of conversation is not,for the most part,to communicate ideas;it is to keep up the buzzing sound.There are,it must be admitted,different qualities of buzz;there is even a buzz that is as annoying as the continuous noise made by a mosquito.But at a dinner party one would rather be a mosquito than a quiet person.Most buzzing, fortunately,is pleasant to the ear,and some of it is pleasant even to the mind.He would be a foolish man if he waited until he had a wise thought to take part in the buzzing with his neighbors.

    Those who hate to pick up the weather as a conversational opening seem to me not to know the reason why human beings wish to talk.Very few human beings join in a conversation in the hope of learning anything new.Some of them are content if they are merely allowed to go on making a noise into other people's ears,though they have nothing to tell them except that they have seen two or three new plays or that they had food in a Swiss hotel.At the end of an evening,during which they have said nothing meaningful for a long time.They just prove themselves to be successful conservationists.

    When school started on that warm August day, I threw myself into everything I did, including playing volleyball. I decided to become beautiful, or at the very least, skinny. I stopped eating completely. Soon I began losing weight, which thrilled me, and I even grew to love the tiredness and lightheadedness( 头晕)that came with my poor diet, for those feelings meant that I was winning.

    As the season progressed, things had become tense between my head volleyball coach, Coach Smith, and me. She felt that something was wrong with my health. She talked with me about my eating and was angry that I wouldn't listen to her when she tried to make me eat. She tried to persuade me in a determined way and so we fought constantly. Then my hunger started to affect my performance. I was so tired that practice and games were becoming a struggle. One afternoon, with hurt in her eyes, Coach Smith asked me what I had eaten and I told her nothing yet. She looked at me, disappointment in her eyes, knowing she couldn't make me stop, and walked away.

    A couple of weeks later I attended a formal dinner for our volleyball team. I stood there as my coach managed to say something nice about me. I realized then that I had ruined my senior year by being disrespectful, and I had probably ruined hers as well. So that evening I wrote her a letter apologizing and thanking her.

    Then one Saturday, as I was reading in the library, I felt someone gently take my arm and say softly, “Lynn Jones, how are you doing?” I looked up and saw the familiar face. “Thanks for the letter,” she said. “It meant a lot.” When I think of a coach, I think of someone above me, someone who gives instruction — not a friend. But Coach Smith is different, and, like any other good friend, she dealt with my problem in a determined way even when I hated her for it at that time. I didn't deserve her kindness, but she gave it anyway. I will forever be grateful for her help, and now for her friendship.

    Have you ever been faced with trying to stay positive when others around you are negative? A negative person can bring you down and throw your positive plans out of the window. Whether you deal with a family member, friend or co-worker who is negative, there are things you can do to remain positive in the face of negativity?

    Whatever you do, don't argue with a negative person. Arguing only adds fuel to the fire. I have noticed when my children are crabby, it is best to avoid trying to ask them to analyze and adjust their attitude. As soon as I take the approach of being in opposition to them, the situation gets worse before it gets better. Sometimes the best thing to do is remain silent and let negativity pass.

    You know how difficult it can be to give love and positive attention to negative people. Unfortunately, that is often exactly what they need. A negative person is usually afraid he is unlovable. How do you show love when someone is negative? You must listen to what he is trying to tell you. Acknowledge the feelings he has by saying something like, "You sound very angry right now." How might you help a negative person? Offer a hug even if you get rejected. A negative person often has difficulty accepting love from others.

    If you have negative people on your life who are affecting your mental and physical health, you need to decide whether or not you want these people in your life. Some people are so negative that you have no other choice but to separate them from your life. However, some people, such as your children, are difficult to remove from your life, in this case, professional counseling(咨询) may be the answer.

    HANGZHOU — Chinese internet giant Alibaba on Tuesday opened a hotel loaded with artificial intelligence (AI) and robots, automating a series of procedures like check­ in, lights control and room service.

    FlyZoo Hotel, opened in Hangzhou, capital of East China's Zhejiang province, where Alibaba is headquartered, is known as the company's "first future hotel". Customers can check into the hotel by simply scanning their faces. The facial recognition system installed in the hotel also enables customers to use their faces as key cards to open doors and access another hotel service. Users can also control the lights, televisions and curtains in the room via Alibaba's voice­activated digital assistant, while robots are deployed to serve dishes, cocktails and coffee. Hotel bookings and check­out can also be done with a few clicks on mobile through an app. "The AI­based solution can help customers save time and relieve hotel employees from repetitive work," said Wang Qun, CEO of FlyZoo Hotel. The hotel is the latest example of Chinese tech companies' attempt into traditional industries such as the hotel industry.

    E­commerce giant JD.com announced in October its strategy to put smart home and electronic devices sold on its platform into hotels, in an effort to improve online sales.

    In July, Baidu teamed up with Intercontinental Hotels Group in Beijing to allow guests to use its voice­ controlled assistant to adjust room temperature and order room service at ease.

    Before that, social media giant Tencent introduced QQfamily, a similar tech solution for hotel operators, in the southern city of Zhuhai last year.

    "We want to install a 'smart brain' for hotels," said Wang. "In the future, we will continue to make hotels smarter and more automated, as well as create more personalized experiences for consumers."
