      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.

    Rosie Dutton, a teacher from Relax Kids in Tamworth, UK, used two apples to show her students the often unseen but harmful effects of school bullying(校园欺凌). She posted the lesson on Facebook, where it's been shared more than 160,000 times.

    Rosie Dutton explained that during one of her classes she presented the children with two red apples. What the kids didn't know was that before the lesson, she had repeatedly dropped one of the apples on the floor. And yet, on the outside at least, both apples looked perfect.

    “I picked up the apple I'd dropped on the floor and started to tell the children how I disliked this apple,” Dutton wrote. “I told them that because I didn't like it, I didn't want them to like it either, so they should call it names too.”Some of the children looked at her as if she were “crazy”, but the students passed the apple around the circle, calling it names.

    Continuing the exercise, the teacher then passed the second apple around the circle. This apple, however, was showered with words like: “Your skin is beautiful,” and “ what a beautiful colour you have.”

    Dutton then showed the students both apples once again, stressing that “there was no change, and both apples still looked the same.”

    Finally, Dutton cut both apples open. The apple that the class treated kindly looked fresh inside. But the other apple—the one they'd treated poorly —was bruised（瘀伤的) beneath its skin.

    “I think there was a light bulb moment for the children immediately,” Dutton said. “When people are bullied, especially children, they feel horrible inside and sometimes don't show or tell others how they are feeling. If we hadn't have cut that apple open, we would never have known how much pain we had caused it.”

    Dutton explained how important it is to teach children to stand up for one another, and to stop any form of bullying.

    “Let's create a generation of kind caring children,” the teacher wrote. “The tongue has no bones, but is strong enough to break a heart. So be careful with your words.”

    If a woman has an extra piece of cake, don't blame it on greed, blame it on her brain.

    Scientists have found that women's brains react to food very differently—and much more strongly—than men's. Academics found that decades of dieting pressure on women and advertising have programmed certain parts of the female brain to react strongly when faced with any kind of food. Men, on the other hand, are not usually as obsessive (着迷的) about what they eat.

    Dr. Rudolf Uher and his colleagues at the Institute of Psychiatry in King's College London used brain scanning technology, known as functional magnetic resonance imaging (FMRI), to look at the brains of eighteen men and women.

The volunteers were given images of food to look at, as well as food to taste. Their brain reactions were observed by the scientists.

    They found that the female brains reacted much more strongly than those of males.

    The same reaction did not happen when they were shown non-food images. The team believe this means women think more about food than men tend to do.

    Dr. Uher said, “This could be related to biological differences between men and women. But the more likely explanation is that women have a more complicated reaction to food because of social pressure.

    Professor Carey Cooper, psychology and health professor at Lancaster University, said, “For centuries women have had a providing role — preparing and cooking food for their families. And it is part of that rule to make sure the food is safe. They will therefore be much more sensitive to food than men are, and I would not be surprised if that was now built into their DNA. If the female brain reacts to food because it historically has developed neural (神经的) pathways to do this, then food will be the way they express their stress. Food actually, is a comfort for women.”

    But other experts have said that more research must be done before the results can be proved. American scientist Angelo del Parigi of the John B. Pierce Laboratory in New Haven, Connecticut, said, “Looking at an FMRI alone cannot make sure whether the stronger reaction in women is due to innate (天生的) differences or a learned process.

    Many people trying to sell homes find that an increase in home prices has turned the market in their favor. But sellers can still get the short end of the deal if they aren't careful. Here are a few tips for you:

    Don't test your luck. Of course you think anyone who moves into your lovely home should be willing to pay top dollars, especially if you've recently invested in some improvements. But listing a home at a price that's too high above the market price could turn away some buyers.

    Buyers noticing that the home which still hasn't been sold may begin to assume there's something wrong with the house and use that as a reasonable excuse for offering a lower price. And if a home hasn't received any offers after two weeks, it might be time to reset the price.

    A price that's too low can bring about an undesired outcome. Listing your home at or slightly below the market price can have the effect of drawing in a large group of buyers and increase the chances that a home will receive multiple offers. But setting the price too low comes with several risks. One possibility is that buyers will get skeptical of the home that is listed for $15,000 to $20,000 less than similar homes in the area, especially if it's not properly marketed. Once again, people might assume there is something wrong with the home and may not bother to look at it.

    Spy on the competition. Going to other people's open houses can give you a better sense of how your home compares with others on the market. Check out the decoration in their kitchens, the size of their backyards and use the information to figure out where your home should fit in the range of the price. But don't set your pricing just on what you see elsewhere.

Owls and Larks

    Larks are most likely to be healthy, wealthy and wise, according to the old saying.

    But those who are early to bed and early to rise do not always have the upper hand, researchers say. They have found that night owls are generally brighter and wealthier than those able to get up early in the morning.

    Experts from the University of Madrid carried out tests on around 1,000 teenagers and found that those who preferred to stay up late proved the kind of intelligence associated with honored jobs and higher incomes. "Larks" or "morning people", however, often acquired better exam results, possibly because lessons are held at the wrong time of day for night owls. The researchers examined the habits and body clocks of the youngsters to determine whether they liked to stay up late and sleep later in the morning, or preferred to go to bed early and were at their peak in the morning. School performance and inductive(归纳的)intelligence, or problem solving, were measured and academic grades in the major subjects were also taken into account. The results showed that evening types scored higher than morning types on inductive reasoning, which has been shown to be a good estimate of general intelligence and a strong indicator of academic(学术的) performance. They also had a greater capacity(能力) to think conceptually(概念地) as well as analytically. Such abilities have been linked to innovative(创新的) thinking, more admired occupations and better incomes.

    Famous night owls include President Trump, Obama, Charles Darwin, Winston Churchill, Keith Richards and Elvis Presley. George W. Bush, who is regularly in bed by 10 p.m., Thomas Edison, Napoleon, Condoleezza Rice, who wakes at 4:30 a.m., and Ernest Hemingway are among those known as larks. Jim Horne, professor of psychophysiology at Loughborough University, said, "Evening types tend to be the more active and creative types, the poets, artists and inventors, while the morning types are the deducers(推导者), as are often seen with civil servants and accountants." A previous study of US Air Force recruits found that evening types were much better at thinking to solve problems than larks.

About two years ago, Coronavirus(新冠病毒) showed up(出现). So many great people are fighting it to protect(保护) us. One of them is Zhong Nanshan. He's 84 years old, but he's still fighting the virus. Thanks to them, China is getting better(情况好转). But this virus is really dangerous. We must be careful all the time. Here are some ways to protect ourselves.

Wear a face mask(口罩).

Wash your hands often.

Don't touch your face, eyes, nose and mouth before washing your hands.

Do some exercise to keep healthy.

China is a very big and old country. Over 5, 000 years, we faced many problems. Fighting this virus is just another one of those problems. At last(最终), we will win.
