Many kids help out around the house with chores(家庭杂务) such as emptying the dishwasher, putting laundry away, and taking out the trash. In exchange, some kids get allowances(补贴) or other rewards such as extra computer time.

    But some people do not think that kids should get rewards for doing chores. Susie Walton, a parenting educator and family coach, believes that by rewarding kids, parents are sending a message that work isn't worth doing unless you get something in return. "Running any kind of household is a team effort," Susie said. "A home is a living space for everyone in the family. It's important for kids to see that we all have responsibilities in the house, and that families decide together how they want their home to look, and how they are going to keep it looking like everyone wants it to look."

    Other people believe that getting a cash allowance or other rewards motivates kids to do chores, and it also teaches them real world lessons about how we need to work to earn money. There are also new applications that give kids points and digital gifts that can be redeemed(兑取) either online or in the real world. With the ChoreMonster app, kids earn digital points by completing chores that they can turn in for real-life rewards such as extra Xbox time or a trip to the mall. "Our goal is to encourage kids to earn rewards," says Chris Bergman, founder of ChoreMonster. "Kids need positive reinforcement(强化) to help motivate them."

    What do you think? Should kids be rewarded for doing chores? Or should kids help out around their homes without getting anything in return?

    One night, the first floor of the house suddenly caught fire. The fire was big, and soon became a sea of fire. On the second floor lived a little girl and her grandmother; the little girl's parents had died, and she lived together with her grandma. In order to rescue the little girl, the grandmother was burned to death, leaving the little girl crying for help loudly.

    How could people enter the house? At the very moment, a man carrying a ladder rushed to the flames and entered the house through the window. When he appeared again in the eyes of the people, the little girl was in his arms. He gave the child to the crowd, and then disappeared into the night.

    This little girl had no family. Two months later a meeting was held to find a person to adopt the girl. A teacher was willing to adopt this child, and said she could give her the best education; a farmer wanted to adopt this child, saying that village life would let the child grow up healthily and happily; a rich man said, “I can give the child everything that others can do.”

    A lot of people who wanted to adopt this child said a lot about the benefits of their adopting the child. But the little girl's face had no expression. At this time, a man, through the crowd, walked straight to the little girl, and opened his arms for the little girl. People were puzzled, and they found that the man had terrible scars on his arms. The little girl let out a cry, “This is the man who saved me!” She suddenly jumped up and buried her face in his arms and sobbed. Naturally the man adopted the girl.

    Most people looking for ways to quit smoking worry about weight gain, and with good reason. Smokers who quit tend to pack on an average of 5 pounds after they stop smoking cigarettes. A new study, published by the journal Science, explains why this happens.

    The new research explains that nicotine appears to combine with appetite-regulating neurons (调节食欲的神经元) in the brain, besides the receptors (感受器) that bring about addiction. These neurons help regulate how much food gets consumed, but under the influence of nicotine, they lose their self-control. This is why when smokers quit, they tend to eat more and gain weight.

    The researchers believe that their discovery will lead to the development of drugs that aim at nicotine receptors on brain cells that control appetite. In the future, weight gain may no longer be a reason for smokers to delay the decision to kick the habit, but that's no reason to wait. Nicotine-replacement treatment, while not for everyone, can help. Here are a few more ways to quit smoking and stay slim.

    Drink water. To improve metabolic (新陈代谢的) rates, make half of those glasses ice water. Juice can be too high in calories, something you'll want to keep an eye on your journey toward being a slimmer non-smoker. Plan your snacks. Healthy snacks help keep your metabolism working, so you continue to burn calories while stopping wild hunger pain, or fake hunger.

    Keep moving. Exercise kills two birds with one stone. It helps you burn calories and prevents you from eating when you're not truly hungry. It's also a feel-good stress reliever (缓解物). Focus on your fitness and how being healthy makes you feel. Make exercise a goal and think of quitting as your reward for being physically fit.

    Hummingbirds (蜂鸟) are very small birds. This small bird is quite an acrobat (杂技演员). Only a few birds, such as kingfishers and sunbirds, can hover, which means to stay in one place in the air. But no other bird can match the flying skills of the hummingbird. The hummingbird can hover, fly backward and fly upside down!

    Hummingbirds got their name because their wings move very quickly when they fly. This causes a humming sound. Their wings move so fast that you can't see them at all. This takes a lot of energy. These little birds must have food about every 20 minutes to have enough strength to fly. Their favorite food is nectar (花蜜). Nectar is the sweet water deep inside a flower. Hummingbirds use their long, thin bills to drink from flowers. When a hummingbird drinks nectar, it hovers in front of a flower. It never touches the flower with its wings or feet.

    Of all the birds in the world, the hummingbird's colors are among the brightest. Some are bright green with red and white markings. Some are purple. One kind of hummingbird can change its color from reddish-brown to purple to red!

    The hummingbird's nest is special, too. It looks like a small cup. The inside of the nest is very soft. This is because one of the things the mother bird uses to build the nest is the silk from a spider's web (蜘蛛网).

    These days, people who do manual (体力的) work often receive far more money than people who work in offices. People who work in offices are frequently referred to as "white-collar workers" for the simple reason that they usually wear a collar and tie to go to work. Such is human nature, that a great many people are often willing to sacrifice higher pay for the honor of becoming white-collar workers. This can lead to curious situations, as it did in the case of Alfred Bloggs who worked as a dustman for the Ellesmere Corporation.

    When he got married, Alf was too embarrassed to say anything to his wife about his job. He simply told her that he worked for the Corporation. Every morning, he left home dressed in a smart black suit. He then changed into overalls (工作服) and spent the next eight hours as a dustman. Before returning home at night, he took a shower and changed back into his suit. Alf did this for over two years and his fellow dustmen kept his secret. Alf's wife has never discovered that she married a dustman and she never will, for Alf has just found another job. He will soon be working in an office. He will be earning only half as much as he used to, but he feels that his rise in status (身份；地位) is well worth the loss of money. From now on, he will wear a suit all day and others will call him 'Mr. Bloggs', not 'Alf'.

    "Bill, you never miss!" Joe said admiringly. "Unless I'm in a real game," Bill complained. "Then I miss all the time." Joe knew that Bill was right. Bill performed much better when he was having fun with Joe in the school yard than he did when he was playing for the school team in front of a large crowd. "Maybe you just need to practice more," Joe suggested. "But I practice all the time with you!" Bill objected. He shook his head. "I just can't play well when people are watching me." "You play well when I'm watching," Joe pointed out. "That's because I've known you since we were five years old," Bill said with a smile. "I'm just not comfortable playing when other people are around." Joe nodded and understood, but he also had an idea.

    The next day Joe and Bill met in the school yard again to practice. After a few minutes, Joe excused himself. "Practice without me," Joe said to his friend. "I'll be back in a minute. "

    Joe hurried through the school building, gathering together whomever he could find-two students, a math teacher, two secretaries, and a janitor(看门人). When Joe explained why he needed them, everyone was happy to help. Joe reminded the group to stay quiet as they all went toward the school's basketball court. As Joe had hoped, Bill was still practicing basketball. He made five baskets in a row without noticing the silent people standing behind him.

    "Hey, Bill!" Joe called out finally. Bill turned. A look of surprise came over his face. "I just wanted to show you that you could play well with people watching you," Joe said. "Now you'll have nothing to worry about for the next game!"
