      The meaning of silence varies among cultural groups. Silences may be thoughtful, or they may be empty when a person has nothing to say. A silence in a conversation may also show stubbornness, or worry. Silence may be viewed by some cultural groups as extremely uncomfortable; therefore attempts may be made to fill every gap(间隙)with conversation. Persons in other cultural groups value silence and view it as necessary for understanding a person's needs.

        Many Native Americans value silence and feel it is a basic part of communicating among people, just as some traditional Chinese and Thai persons do. Therefore, when a person from one of these cultures is speaking and suddenly stops, what maybe implied(暗示) is that the person wants the listener to consider what has been said before continuing. In these cultures, silence is a call for reflection.

        Other cultures may use silence in other ways, particularly when dealing with conflicts among people or in relationships of people with different amounts of power. For example, Russian, French, and Spanish persons may use silence to show agreement between parties about the topic under discussion. However, Mexicans may use silence when instructions are given by a person in authority rather than be rude to that person by arguing with him or her. In still another use, persons in Asian cultures may view silence as a sign of respect, particularly to an elder or a person in authority.

Nurses and other care-givers need to be aware of the possible meanings of silence when they come across the personal anxiety their patients may be experiencing. Nurses should recognize their own personal and cultural construction of silence so that a patient's silence is not interrupted too early or allowed to go on unnecessarily. A nurse who understands the healing(治愈) value of silence can use this understanding to assist in the care of patients from their own and from other cultures.

    People are being lured(引诱) onto Facebook with the promise of a fun, free service without realizing they're paying for it by giving up large amounts of personal information. Facebook then attempts to make money by selling their data to advertisers that want to send targeted messages.

    Most Facebook users don't realize this is happening. Even if they know what the company is up to, they still have no idea what they're paying for Facebook because people don't really know what their personal data is worth.

    The biggest problem, however, is that the company keeps changing the rules. Early on, you keep everything private. That was the great thing about Facebook—you could create your own little private network. Last year, the company changed its privacy rules so that many things—your city, your photo, your friends' names—were set, by default(默认) to be shared with everyone on the Internet.

    According to Facebook's vice-president Elliot Schrage, the company is simply making changes to improve its service, and if people don't share information, they have a “less satisfying experience”.

    Some critics think this is more about Facebook looking to make more money. Its original business model, which involved selling ads and putting them at the side of the page, totally failed. Who wants to look at ads when they're online connecting with their friends?

    The privacy issue has already landed Facebook in hot water in Washington. In April, Senator(议员) Charles Schumer called on Facebook to change its privacy policy. He also urged the Federal Trade Commission to set principles for social-networking sites. “I think the senator rightly communicated that we had not been clear about what the new products were and how people could choose to use them or not to use them，” Schrage admits.

    I suspect that whatever Facebook has done so far to invade our privacy is only the beginning, which is why I'm considering deactivating (撤销) my account. Facebook is a handy site, but I'm upset by the idea that my information is in the hands of people I don't know. That's too high a price to pay.

    Maybe it has been the influence of the current scene: the type among urban biking. Apparently, urban biking requires entirely different bikes than suburban hiking does and therefore a Bike Design Project started where five design studios across five cities had to come up with a perfect urban bike. The winning bike will be manufactured for a limited run of 100 hikes and will be in stores next year. Industry, a Portland-based studio, came up with a very interesting bike: one that uses bluetooth and handlebars (车把手) that tell you when to stop or turn.

    Industry worked together with Ti Cycles to create a bike with a 3D printed titanium frame (钛框架). The hike is called Solid and can be connected to a smartphone APP: My Bike. This APP alarms a user when a light needs replacement and if something gets wrong with one's brakes. There is also software called Discover My City, which has a series of routes through Portland's most trendy neighborhoods, with suggestions about where to eat and shop.

    Nevertheless, the idea with cycling is that you need to focus on the road and not on your smartphone. This bike therefore uses integrated feedback on handlebars. Those handlebars tell a user when to turn, as they will buzz when a turn appears. As you are getting closer, they will buzz more frequently. And then there is the possibility to control your light via built-in sensors and change gears by pressing an electronic button.

    Although the bicycle looks highly interesting and can be seen as a piece of art for the designing world, we don't know if we would like our bike to have an automatic buzz when we are approaching a turn. On the other side, it could add some extra safety to traffic in general. Whether you like the bike or not, you have to admit the Portland-based studio brings the concept of urban biking to a whole new level.

    For a long time being happy was considered something that just happened, and there was nothing special about it. Now we know that getting along with other people is something that we can work at. It is possible to act in such a way that other people will like us better. One way is being unselfish, not wanting everything from our friends. Another way is to look for good points, not bad ones in other people. It is surprising how successful this treasure hunt can be.

    You don't have to be spineless (软弱的) in order to be popular. In fact, you will be liked and respected if you are not afraid to stand up for your rights. But do it politely and pleasantly. Being friendly and polite to your group, to other people and to strangers and especially to those who do not look important or do not interest you is one way to develop a good character.

    You can not expect to be perfect, and so you must learn not to be unhappy when you make mistakes. Everyone makes mistakes, and no one is to be blamed (责备) unless he refuses to learn from them. Many young people become discouraged when they know in themselves qualities (品格) that they do not like—selfishness, laziness, and other unpleasant qualities. Just remember that we all have some of these faults and have to fight against them.

    At the same time, it is important to remember that, while you are probably no worse than others, the best way to be happy is to think yourself above other people. When something is wrong, it is good sense to try to make it right. Perhaps you don't like a teacher or a classmate. Try to see why, and look at yourself, too. To be sure that you are not doing anything to make that person dislike you. Some day, things may turn out all right, then you will have to learn to get along the best with situation, without thinking too much about it. Worrying never helps in a situation you can't change.

    Arriving in Sydney on his own from India, my husband, Rashid, stayed in a hotel for a short time while looking for a house for me and our children.

    During the first week of his stay, he went out one day to do some shopping. He came back in the late afternoon to discover that his suitcase was gone. He was extremely worried as the suitcase had all his important papers, including his passport.

    He reported the case to the police and then sat there, lost and lonely in strange city, thinking of the terrible troubles of getting all the paperwork organized again from a distant country while trying to settle down in a new one.

    Late in the evening, the phone rang. It was a stranger. He was trying to pronounce my husband's name and was asking him a lot of questions. Then he said they had found a pile of papers in their trash can(垃圾桶)that had been left out on the footpath.

    My husband rushed to their home to find a kind family holding all his papers and documents. Their young daughter had gone to the trash can and found a pile of unfamiliar papers. Her parents had carefully sorted them out, although they had found mainly foreign addresses on most of the documents. At last they had seen a half-written letter in the pile in which my husband had given his new telephone number to a friend.

    That family not only restored the important documents to us that day but also restored our faith and trust in people. We still remember their kindness and often send a warm wish their way.

On Monday, a scientist and doctor Robert Winston is to formally ask a question in congress about what assessments the government has made "for requiring adults riding bicycles in city centres to heave a licence and third-party insurance". The letter below is the entirely imagined response I would like the government to make to him.

Dear Robert,

You ask what assessments we've made for your proposal about obliging cyclists to have licences and insurance. The brief answer is: none. Nor do we have any plans to do so.

Why? Again, the short answer is this: it's a silly and pointless thing to suggest, as evidenced by the fact that practically no countries or territories anywhere in the world require cyclists to be licensed, or to have compulsory insurance.

I suppose it's only fair if I explain why I think it is such a non-issue. It's pretty simple: such a plan would achieve pretty much nothing, while causing significant problems. More widely, any sensible governments will do everything in their power to get more people cycling, not to put pointless obstacles in their way.

Let's just take one example. As I'm sure you know as a doctor, one of the problems facing our nation is that the National Health System is likely to collapse under the caring for an increasingly overweight population. Inactive living is central to this. Even a fairly brief daily bike trip can have miraculous benefits for people's health.

Next, how would such rules even work? Would the licensing and insurance be just for adults, or also children? How would the system even be enforced-would it also require all bikes to be registered with number plates?

Finally, what would you hope to achieve by this? If you believe licensing transport users stops wrongdoing, can I point to you the data showing how a third of drivers admit to using handheld phones while driving, despite the law forbidding it.

So, to summarize：your plan would be to introduce a hugely new administrative scheme that would most likely have limited effect on the behaviour of averagely law-abiding (守法的) transport users who rarely harm others, while putting people off from this beneficial type of transport.

I'm afraid I just don't get it.
