Money Matters

    Parents should help their children understand money. {#blank#}1{#/blank#}So you may start talking about money when your child shows an interest in buying things, candy or toys, for example.

1）The basic function of money

    Begin explaining the basic function of money by showing how people trade money for goods or services. It is important to show your child how money is traded for the things he wants to have. If he wants to have a toy, give him the money and let him hand the money to the cashier(收银员). {#blank#}2{#/blank#} When your child grows a bit older and understands the basic function of money, you can start explaining more complex (复杂的) ways of using money.

2）Money lessons

    Approach money lessons with openness and honesty. {#blank#}3{#/blank#} If you must say NO to a child's request to spend money, explain, “You have enough toy cars for now.” Or, if the request is for many different things, say, “You have to make a choice between this toy and that toy.”

3）{#blank#}4{#/blank#}

    Begin at the grocery store(杂货店). Pick out two similar brands（商标） of a product—a name-brand butter and a generic (无商标产品), for example. You can show your child how to make choices between different brands of a product so that you can save money. {#blank#}5{#/blank#}If he chooses the cheaper brand, allow him to buy another one with the money saved. Later, you may explain how the more expensive choice leaves less money for buying others.

A. Talk about how the money bought the thing after you leave the toy store.

B. The value of money

C. The best time to teach a child anything about money is when he shows an interest

D. Permit the child to choose between them

E. Ask yourself what things that cost money are most important to you

F. Tell your child why he can or can't have certain things

G. Wise decisions

    With the approval of the Singapore government, a company called nuTonomy has become the first-ever to test self-driving cars with the public. Interested people could sign up for a free trial run at no cost. When they received an invitation from the company, they could book a ride on the driverless taxi service from their smartphones.Not surprisingly,the rides proved very popular,with dozens of customers eagerly trying out the cars each day.

    Driverless cars are a great option for those who do not know how to drive and for those who do not enjoy driving.Some researchers even believe that such cars can make road travel safer by reducing human errors.But since driving requires many of our senses to be on alert（高度警觉）, replacing that by machines is easier said than done.

    The environment in which cars operate is constantly changing—from roads and pedestrians to co-travelers. A driverless car needs special equipment to analyze its surroundings. Then, it must translate that information into a practical route and safe travel. To be truly autonomous, a car has to do this independently without human input. Today, some cars have a certain degree of autonomous functions. But even the completely automated vehicles still require a driver to take back control under uncertain conditions.

    The island city-state is well known for excellent roads and drivers who obey the rules. This has made it ideal for real-world testing and feedback. The government has encouraged research in autonomous vehicles, since it can improve safety and potentially reduce the traffic burden as well.

    We all have dreams sometimes. Some are sweet but some are nightmares. Almost all researchers in sleep explain that nightmares are a reaction to negative experiences that happen during waking hours. However, some of them believe that nightmares do have some real benefits. One 2017 study, for example, found that frequent nightmare sufferers rated themselves as more empathetic（共鸣的）.They also displayed more of a tendency to unconsciously mirror other people through things like yawning. People who have constant nightmares also tend to think further outside the box on psychoanalysis tasks. Some other researchers have found support for the idea that nightmares might be linked to creativity.

    People seeking cure for nightmares were not necessarily more fearful or anxious, but rather had a general sensitivity to all emotional experience. Sensitivity is the driving force behind intense dreams. Heightened sensitivity to threats or fear during the day results in bad dreams and nightmares, whereas heightened passion or excitement may result in more intense positive dreams. And both these forms of dreams may feed back into waking life, perhaps increasing suffering after nightmares, or promoting social bonds and empathy after positive dreams.

    The effects go further still. This sensitivity overflows over into perceptions and thoughts: people who have a lot of nightmares experience a dreamlike quality to their waking thoughts. And this kind of thinking seems to give them a creative edge. For instance, studies show that such people tend to have greater creative talent and artistic expression. And people who often have nightmares also tend to have more positive dreams than the average person.

    The evidence points towards the idea that, rather than disturbing normal activity, people who are unfortunate in having a lot of nightmares also have a dreaming life that is at least as creative, positive and vivid as it can be distressing and terrifying. What's more, this imaginative richness is unlikely to be limited to sleep, but also is filled with waking thought and daydreams. Even after people wake up and shake off the nightmare, in other words, a mark of it stays behind, possessing them throughout the day.

    A newly-published study has shown that loneliness can spread from one person to another, like a disease.

    Researchers used information from the Framingham Study, which began in 1948. The Framingham Study gathers information about physical and mental( 心 理 的 ) health, personal behavior and diet. At first, the study involved about 5,000 people in the American state of Massachusetts. Now, more than 12,000 persons are taking part.

    Information from the Framingham Study showed earlier that happiness can spread from person to person. So can behaviors like littering and the ability to stop smoking.

    University of Chicago psychologist (心理学家) John Cacioppo led the recent study. He and other researchers tried to show how often people felt lonely. They found that the feeling of loneliness spread through social groups.

    Having a social connection with a lonely person increased the chances that another person would feel lonely. In fact, a friend of a lonely person was 52% more likely to develop feelings of loneliness. A friend of that person was 25% more likely. The researchers say this shows that a person could indirectly be affected by someone's loneliness.

    The effect was strongest among friends. Neighbors were the second most affected group. The effect was weaker on husbands and wives, and brothers and sisters. The researchers also found that loneliness spread more easily among women than men.

    The New York Times newspaper reports that, on average, people experience feelings of loneliness about 48 days a year. It also found that every additional friend can decrease loneliness by about five percent, or two and a half fewer lonely days.

    Loneliness has been something to do with health problems like sadness and sleeping difficulties. The researchers believe that knowing the causes of loneliness could help in reducing it.

    The study suggests that people can take steps to stop the spread of loneliness. They can do this by helping individuals they know who may be experiencing loneliness. The result can be helpful to the whole social group.

    According to a recent report, about 15% of the people in the UK are members of gyms. But are they more likely to be fit?

    A study found that gym members were 14 times more active than people who didn't belong to any health club. Gym members did six hours more exercise a week, and this activity did make them fitter than non-gym members. They also spent less time sitting down every day than non-gym members. The results were the same for men and women.

    The study included 405 people between the ages of 30 and 64, and the main characteristics of those who were gym members were the same as those who were not. “But gym members did more training than non-gym members,” said the lead author, Elizabeth Schroeder of the University of Illinois.

    While it might seem clear that gym members exercise more and are healthier than non-gym members, Schroeder says this has not been directly shown before. However, the study is only designed to show a tie between gym membership and more exercise. It may be that active people like to join gyms. In the study, people who exercised as much as gym members were also in good health.

    You can get the same benefits wherever you exercise. This study shows a gym membership can make you do more exercise, but other research shows that exercising outside has other help. Outdoor activity can make you feel happy about life—especially if you run through a forest.

    Outdoor exercise is also more interesting than going to the gym. The first five minutes of outdoor exercise is especially helpful in making people feel good. But Schroeder says that a gym may also encourage greater exercise because it can be social and fun.

    Before the 1830s, most newspapers were sold through annual subscriptions in America, usually $8 to $10 a year. Today $8 or $10 seems a small amount of money, but at that time these amounts were forbidding to most citizens. Accordingly, newspapers were read almost only by rich people in politics or the trades. In addition, most newspapers had little in them that would appeal to a mass audience. They were dull and visually forbidding. But the revolution that was taking place in the 1830s would change all that.

    The trend, then, was toward the "penny paper"-a term referring to papers made widely available to the public. It meant any inexpensive newspaper; perhaps more importantly it meant newspapers that could be bought in single copies on the street.

    This development did not take place overnight. It had been possible(but not easy)to buy single copies of newspapers before 1830,but this usually meant the reader had to go down to the printer's office to purchase a copy. Street sales were almost unknown. However, within a few years, street sales of newspapers would be commonplace in eastern cities. At first the price of single copies was seldom a penny-usually two or three cents was charged-and some of the older well-known papers charged five or six cents. But the phrase "penny paper" caught the public's fancy, and soon there would be papers that did indeed sell for only a penny.

    This new trend of newspapers for "the man on the street" did not begin well. Some of the early ventures(企业)were immediate failures. Publishers already in business, people who were owners of successful papers, had little desire to change the tradition. It took a few youthful and daring businessmen to get the ball rolling.
