The U.S. Postal Service(USPS) is losing billions of dollars a year. The government company that delivers "small mail" is losing out to email and othertypes of electronic communication. First-classmail amount fell from a high point of 104 million pieces in 2000 to just 64million pieces by 2014.

    Congress permits the 600,000-empIoyee USPS to hold a monopoly (垄断) overfirst-class and standard mail. The company pays no federal, state or local taxes; pays no vehicle fees; and is free from many regulations on other businesses. Despite these advantages, the USPS has lost $52 billion since 2007, and will continue losing money without major reforms.

    The problem is that Congress is preventing the USPS from reducing costs as its sales decline, and is blocking efforts to end Saturday service and close unneeded post office locations. USPS also hasa costly union-dominated work force that slows the introduction of new ideas ormethods down. USPS workers earn significantly higher payment than comparable private-sector workers. The answer isto privatize the USPS and open postal markets to competition. With the riseof the Internet, the argument that mail is a natural monopoly that needs government protection is weaker than ever.

    Other countries facing declining letter amounts have madereforms. Germany and the Netherlands privatized their national postal companies over a decade ago, and other European countries have followed suit. Britain floated shares of the Royal Mail on its stock exchange in 2013. Some countries, such us Sweden and New Zealand, have not privatized their national postal companies, but they have opened them up to competition.

    These reforms have driven efficiency improvements in all of these countries. Additional number of workers have been reduced, productivity has risen and consumers have benefited. Also, note that cost-cutting measures—such as closing tone post offices—are good for both the economy and the environment.

    Privatization and competition also encourage new changes. When the USPS monopoly over "extremely urgent" mail was stopped in 1979, we saw an explosion in efficient overnight private delivery by firms such as FedEx.

    The government needs to wake up to changing technology, study postal reforms abroad and let businessmen reinvent our out-of-date postal system.

    As a child grows out of being an infant and begins to notice and react to the world around him, you may find yourself wondering how you possibly impart all of the things that he needs to become a responsible, respectful adult.{#blank#}1{#/blank#} A child who learns to respect all he meets not only receives respect from others, but also learns to respect himself as well.

●Show your child respect. This is perhaps the best way to teach your child how to respect others. Listen to your child by giving him your full attention and he will learn to listen to you, understanding how important this is in communication.

●{#blank#}2{#/blank#} The more you say “please” and “thank you” to your child, the more likely he will learn to use them with you and others. Politeness then becomes a normal part of any conversation.

●Agree to disagree.{#blank#}3{#/blank#} Explain your decision so that he will understand your reasoning and expect respectful responses. Disagreeing with you doesn't equate to disobedience.

●Control your impulse to overact. When a situation arises between you and your child that requires calmness, keep in mind that you are supposed to be modeling correct behavior. {#blank#}4{#/blank#}

●Praise, praise, praise! So much is focused on what a child does wrong and how to correct it that the accomplishments are not celebrated enough.{#blank#}5{#/blank#}

A．Teach manners by using polite requests and responses.

B．Try to remember that a child won't always agree with you.

C．Respect is necessary for a meaningful and successful life.

D．If he sees you lose temper, he is more likely to respond that way in future.

E．A child may act like he pleases, but will respect being given limits.

F．When you see your child exhibit respectful behavior, make sure he knows just how proud you are of him.

G．Setting a good example is the best way to start a child on the path to respect.

    Back in 1969, it was the Apollo 11 crew who flew to the moon in a spaceship. When U.S. astronauts Neil Armstrong and Edwin “Buzz” Aldrin stepped foot on the moon, they were the first. Meanwhile, their fellow astronaut Michael Coilins circled the moon in their spaceship, named Columbia.

    When Armstrong and Aldrin were done with their walk，they returned to the command module, and back to Earth. That part of the spaceship is on view at the Smithsonian's Air and Space Museum in Washington, D.C. But, if you cannot get to Washington，soon you will be able to see Columbia on your computer or your smartphone.

    Digital scientists are scanning the inside of the spaceship. They are creating an online model, in three dimensions, or“3 D”. By looking at these photographs, you will be able to see outer space，the way the astronauts did. It will be like sitting in their seats.

    Want your very own Columbia spaceship? You will be able to print a 3D copy of Columbia. Experts say anyone can make a life-sized model. But they expect most people to make smaller models of the 320×400 cm(11'X 13')command module.

    Scientists are using special 3D technology to scan the inside. They use cameras on long arms to take the photographs. The thousands of photographs taken will be combined with 50 laser scans.

    What would it be like to sit inside Columbia and take a look around? All the images will be loaded into software that allows you to look around the module on a computer screen. The user will be able to see the Columbia both inside and out. The Smithsonian says that the 3D technology gives the user ways to see things they cannot see at the museum. And it will give information that even the museum curators(馆长)have not seen before.

    “With the Command Module, no one has been inside since it came into the collection,” says Adam Metallo. Smithsonian 3D imaging specialist. “Now the information we capture can give anyone in the world a view of what it looks like inside this incredible piece of history.”

    A good relationship between students and teachers makes the classroom a very inviting place. When you like your teachers, it's easier to pay attention to their explanations and improve your marks. When you consider your teachers as friends, you'll certainly have more respect for them. When your teachers consider you to be a friend, they'll feel more open in class and that will probably influence the classroom in a positive way. Now here are some tips to develop a friendly relationship with your teachers:

    Ask questions. If you have any questions about that subject, ask them. Show them that you're interested in their subjects. That will make them notice you. But never ask questions that you already know the answers to. If your teachers realize that you are not asking real questions, they might think that you're not actually trying to learn, but only trying to make an impression.

    Talk about non-school subjects. When you see one of your teachers in the hall, greet him/her and ask if he/she is going to that concert or if he/she has seen that movie. That way you'll show that you consider him/her as a reined. Some teachers don't like to have friendly relationships with students, but most of them are happy to chat with their students. After a while, they may start to talk with you about non-school subjects in the classroom.

    The rest is totally up to you; it is very easy to develop a friendly relationship with any of your teachers. If you want to be friends with your teachers, just treat them as friends, but don't forget that no matter how good friends you are, they will still be your teachers and deserve your respect.

After a busy morning, lunch can feel like just the pick-me-up you need-but sometimes the meal that you thought would energize you is the very thing that makes you want to nap at your desk.

Feeling tired after lunch, or post-meals in general, is known as postprandial somnolence—or, colloquially, the food coma.

Part of this phenomenon is due to basic physiology (生理学): When humans eat, most of our blood goes to the digestive organs to process the food, said Sandra Arévalo, director of community health and wellness at Montefiore Nyack Hospital in New York state.

The tendency to get tired after eating isn't inherently suggestive of something amiss (出错的). But there can be additional factors that worsen this natural response, making getting through the rest of the workday or any activities feel like a slog. Here's what to watch out for and how to make adjustments.

When it comes to why you feel overly tired after eating, a common cause is consuming meals that are heavy in terms of quantity or quality. Not eating breakfast can lead to overindulging later in the day if excessive (过度的) hunger makes controlling your appetite difficult, Arévalo said.

Sometimes, however, the makeup of certain foods can contribute to tiredness. Fats are the hardest nutrient to digest because their molecules are much larger than those of protein or carbs, said Julie Stefanski, a spokesperson for the Academy of Nutrition and Dietetics. If you had a meal high in fat—such as fried foods or pizza—that could make you feel tired. Meals high in added sugar or refined or highly processed carbohydrates can have the same effect.

The fiber in so-called whole foods like corns slows the absorption of sugar into the body, which means they don't cause blood sugar or insulin spikes and instead give you more stable, lasting energy, said Kristin Kirkpatrick, a registered dietitian at the Cleveland Clinic.

"A five-minute walk or something helps to improve circulation and alertness (机敏), as well," Arévalo said.
