In the United States, when one becomes rich, he wants people to know it. And even if he does not become very rich, he wants people to think that he is. That is what “keeping up with the Joneses” is about. It is the story of someone who tried to look as rich as his neighbors.

    The expression was first used in 1913 by a young American called Arthur Momand. He told this story about himself. He began earning $ 125 a week at the age of 23. That was a lot of money in those days. He got married and moved with his wife to a very wealthy neighborhood outside New York City. When he saw that rich people rode horses, Momand went horseback riding every day. When he saw that rich people had servants, Momand and his wife also hired a servant and gave big parties for their new neighbors.

    It was like a race, but one could never finish his race because one was always trying to keep up. The race ended for Momand and his wife when they could no longer pay for their new way of life. They moved back to an apartment in New York City.

    Momand looked around him and noticed that many people do things just to keep up with rich lifestyle of their neighbors. He saw the funny side of it and started to write a series of short stories. He called it “Keeping up with the Joneses” because “Jones” is a very common name in the United States. “Keeping up with the Joneses” came to mean keeping up with rich lifestyle of the people around you. Momand's series appeared in different newspapers across the country for over 28 years.

    People never seem to get tired of keeping up with the Joneses. And there are “Joneses” in every city of the world. But one must get tired of trying to keep up with the Joneses because no matter what one does, Mr. Jones always seems to be ahead.

    Last year, I was on a plane with my friend, waiting for it to take off. The pilot's voice was heard throughout the plane: “Sorry for the delay, ladies and gentlemen. Our engines don't work. We are going to jump-start them. Once we get them going, we'll get up in the air and see what happens.”

    That was all he said. “See what happens? Shouldn't we have had a better plan than that?” At that point, I could only laugh nervously. One woman started crying: “Oh, no! We are going to crash!” There are sighs of desperation and anxiety, and we hadn't even taken off yet.

    The pilot even seemed unhappy. He told us one engine was working double time, and his plan was to get up in the air and see what happens! Then we did. We got up in the air, and what happened? Nothing. We arrived in Norfolk, and no sooner had the wheels touched down than applause burst out as everyone on the airplane breathed a sigh of relief.

    All too often, people stop achieving their goals just because they don't have a guaranteed result. But success will never be guaranteed. The best thing that you can do is to just get up in the air, and see what happens.

    If your aim is to build a business, then get up in the air and see what happens! Don't give yourself all the reasons why you can't. Do not wait until you have everything you need. You never will.

    If your goal is to start a friendship, say “Hello”, get up in the air and see what happens! The results could be very rewarding. If your goal is to learn a new skill, get up in the air and see what happens! It might not be as difficult as you think. It could be fun!

    The most important thing to keep in mind when going into high school is to be yourself. Besides, I don't know what your middle school was like, but high school teachers will not care about things such as how much homework you already have in one night. It's best to just learn to deal with things and manage your time wisely so you can achieve everything you need to.

    I think almost every kid feels both nervous and excited before their first day. You will probably love it. I know I did. You should join some sports or activities that will make your high school experience more enjoyable.

    Good luck!

    When I started high school I was really nervous too, especially since I had been homeschooled all through middle school and didn't really know anyone. I suppose the best advice would be to just relax. The first couple of days can be a little bit hard, but things will become easier before you know it.

    I am not going to lie. The first day is kind of frightening. But you'll get used to it. Don't be afraid of anyone; upperclassmen will pick on you more if you let them know you're afraid. Just take it easy. Making some friends and staying with them will greatly help you get used to high school quickly. After the first week it's really not bad at all. Don't worry.

    Getting paid to stay in bed all day sounds pretty good. But what if someone offered you $23,000 to stay in bed for two months? That's the deal that are search team is offering to 24 volunteers.

    Researchers are looking for volunteers to help them study the influences of weightlessness on the human body by spending 60 days lying down. Lying in bed isn't exactly the same as being weightless, but the influences on the human body are similar.

    When astronauts spend a long time in an environment with no gravity(重力), like the International Space Station (ISS),their bodies are affected in many ways. After a couple of months on the ISS, astronauts' hearts don't beat as hard. Their muscles（肌肉）become weaker because they no longer have to work against gravity. Their bones may break more easily. There may also be changes in the astronauts' sleep habits.

    Dr. Arnaud Beck, the researcher in charge of the study, said his goal is to measure the influences of weightlessness, and also to find ways to prevent problems. The study will take 88 days altogether. During the first two weeks the volunteers will be tested to establish(确定) their levels of fitness. Then they will spend 60 days lying in bed with their heads slightly lower than their bodies. They will have to do everything while lying down, including brushing their teeth and going to the bathroom. Dr. Beck said the rule is that they must have at least one shoulder touching the bed at all times. Half of the volunteers in the study will be taking capsules(胶囊) containing special food supplements（增补物）several times a day to see if they help reduce the health problems caused by weightlessness. The last two weeks of the study will be spent trying to let the volunteers recover. Volunteers must be men between the ages of 20 and 45 who are in perfect health. They must be non-smokers.

    The study will take place from September 1^st to November. The first two days are the time for volunteers to sign in.

    I had a teacher who used to wake up in class by shouting: "The early bird gets the worm!" I say "let him have the worm". I hate food that doesn't stay still, and avoid Japanese restaurants for that very reason. Anyway, I stopped eating worms at the age of three, switching to regular breakfasts of cereal(谷物), to which I would add extra sugar.

    Recently I was thinking about early birds and the competitive spirit after receiving a letter from a reader in Malaysia: "My son deliberately throws away marks because he doesn't like to be top of the class. What shall I do?" Give him a round of "applause" for being smart! Actually many children in Asia tend to be the focus by performing better.

    Placed into a very competitive class when I was 11, I quickly learned the ideal position was second to last. The top three performers and the very last person are highlighted; the second-to-last contestant is INVISIBLE. And it's an easy position to get—just deliberately underperform at every test. I could do that. I once came second to last in eight straight sports day races. No one suspected anything. I was so invisible that I could have robbed a bank in my street and no one would have noticed.

    At the London Olympics a few months ago, badminton pairs from three Asian countries deliberately tried to lost matches to draw good lots in later rounds. It was funny to watch, but they were all thrown out for poor sportsmanship. What they really needed were acting lessons, their moves were so unconvincing. "Oops, I hit the ball in entirely the wrong direction."

    The other day, I took the children out and they raced for the car. "I'm first," said one. The second said: "First is worst, second is best." Together they sang at the last one: "And third's the one with a hairy chest."

    It struck me that the organizers of sports matches could use this song when people deliberately lost matches. "I lost," the delighted loser will say. The judges could still declare them winners, pointing to a new, optional regulation: "First is worst, second is best, third's the one with a hairy chest."

    Living in the wild can be hard. Finding food and staying safe aren't easy. Each day, animals try to survive in their habitats. Not all animals get by on their own. Some animals form a close partnership with other kinds of animals. These pairings are called symbiotic(共生的)relationships.

    In a symbiotic relationship, the animals depend on each other. One animal helps the other meet its needs. Sounds good, right? Not always. Some animals are not very kind to their partners. In some cases, one animal meets its needs but hurts its partner. Take ticks(扁虱), for example. These insects suck blood to live. To get blood, they attach themselves to other kinds of animals. Ticks can pass germs(细菌)that cause disease instead of helping their hosts.

    In other relationships, animals don't treat their partners so poorly. Both animals benefit from living with the other animal.

    Small animals called cleaner shrimps(清洁虾)have found a way of helping fish. As their name suggests, the shrimps clean the fish. They hang out at what scientists call a cleaning station. A fish stops by. Then a shrimp climbs onto the fish and even steps into the fish's mouth. The shrimp uses its tiny claws to pick stuff off the fish's body. That can include dead skin and tiny pieces of food that can hurt the fish. The fish gets a nice cleaning. The shrimp enjoys a tasty meal of fish trash.

    Small birds called plovers(灰斑)are also in the cleaning business. They have big customers-crocodiles. Crocodiles have long noses filled with sharp teeth. Cleaning them is funny. When a crocodile opens its mouth, the plover hops right in. It lets the plover eat small, harmful animals attached to the crocodile's teeth. The plover gets an easy meal while the crocodile gets clean teeth.
