How strong are you?

    That is a hard question to answer, whether you are a man or a woman. But, really , I want to ask how do you define(给...下定义)your strength? How do you know your limits?{#blank#}1{#/blank#} When push comes, we often discover that we are much stronger than we think.

    What is Strength?

    Strength is not always about pure physical strength.{#blank#}2{#/blank#} It is about the ability to get things done. I know some people who are intellectually strong, but they get very little done in their jobs. And I know others who find work challenging, but they make it by strong drive and hard work. They possess inner strength.

    Self-Imposed Limits

    What I have observed is that most people set their own limits. They limit their output based on self-framed limits (自我设定的限制) of their abilities and strengths. Sometimes these boundaries are based on past experiences. Sometimes they are based on self-imagined abilities.{#blank#}3{#/blank#}So, how do we break through these limits? How do we get stronger?

    {#blank#}4{#/blank#}

    If you want to be stronger, you have to push your boundaries. Pushing it is what it takes to increase your limits. In the gym, bodybuilders discovered this long ago. The same principle is true when it comes to inner strength.

    Want to test your limits? Push yourself. Test your self-framed limits to see how accurate they are. Make sure your goals are slightly beyond what you think can be achieved.

    You Are Stronger Than You Think

    Most people underestimate(低估) their strength.{#blank#}5{#/blank#}Test your limits. Push yourself to find your true boundaries and define your strength.

    When you discover how much you've really got, you may surprise even yourself.

A. Certainly, it is about willpower.

B. Sometimes these limits are based on nothing.

C. How do you know just how much you've got?

D. Pushing It

E. As you go through your day, challenge your ability.

F. How can we train our mind and make it stronger?

G. Strength is a combination of physical and mental ability.

You must have written your research paper, your personal essay, your book review—-whatever your school class requires. You think you have provided good information in the needed number of words.{#blank#}1{#/blank#}

    But is it really done? Many teachers and professional writers believe that writing is revision.{#blank#}2{#/blank#}

Revision of writing is a necessary skill for students. The classroom is a good place to practice patience, concentration and listening. There are rewards with spending time with your thoughts and really taking time to compose your ideas in an orderly and reasonable way. You should put away your paper after you have written a first version, or draft. Wait several hours, maybe overnight, before working on it more.{#blank#}3{#/blank#} Not only are you refreshed, but you're looking at things through different eyes. That's what revision literally means—to see again through different eyes.

Following a four-step process may help you with your paper. The first step in the process is invention. It includes forming many questions about your subject. It is called “question-storming”.{#blank#}4{#/blank#}Then comes the revision period. Take your time to read what you've written, to think about it, and maybe to re-shape it based on what you see now, as a kind of new person looking at it with a reader's eyeglasses rather than a writer's. The fourth step is called “publication”.{#blank#}5{#/blank#}In a sense, anytime you turn it over to another person, that's publication.

    Probably, the process takes away some of the tension of writing. And worry about the quality of your writing often disappears when you share that writing.

    Dolphin or not a dolphin? That is the question! You see, there are several types of dolphins. Some are saltwater dolphins while others are river dolphins.

    "What are the 32 types of dolphins?" When people are asking the question, they are actually referring to the saltwater dolphins in oceans and seas. The river dolphins living in fresh water are not included in these species. But what would be the answer in this case if we ask. "Dolphin or not a dolphin?" The answer would obviously be yes. River dolphins still belong to the dolphin family.

    Among the 32 types of dolphins do not actually wear the word "dolphin" in their names, such as the tucuxi, while others actually have the word "whale" as part of their names even if they are not whales but in fact, belong to the dolphin family, for example, the melon-headed whale and the killer whale. So what would be the answer to the question "Dolphin or not a dolphin?" in these cases? It would be yes. All these species do belong to the dolphin family.

    Another question that people ask is. "Are the sea animals that perform at aquariums(水族馆)all dolphins?" So ,it always seems to come back to the question, "Dolphin or not a dolphin?" Well the answer is no in this case. The sea animals that perform there are not all dolphins. The beluga which people tend to think belong to the dolphin family because they show what seems like a smile, like most dolphins, are in fact a species of the whale family.

    Now that you read these facts about dolphins, you probably realize that certain sea animals may appear to be part of the dolphin species and that others seem to be part of the whale family but in either case, it is not obvious and can be surprising when you identify a sea animal as being a dolphin or not a dolphin. That is the question ！

    Confident, smart and high-tech, they're followers of pop culture and know what social networking is all about. They're tweens, children between the ages of 10 and 12. These young people are no longer little kids but they are not yet teenagers, because tweens are in a state of transition (转变).

    The tween years are hard for children. From a social point of view, tweens are dealing with quite a lot. They have to face changing relationships, middle school and a whole lot of pressure (压力) to succeed and fit in. They may become angry over seemingly small things. A bad test grade, an argument with a friend, a bad day on the ball field, or a request to clean a bedroom might set them off.

    Elizabeth Hartley-Brewer, a parenting expert in London and author of Talking to Tweens, says, "The tween years are when young people begin to realize the wider world and to see themselves as separate from their families."

    Right now, tweens' friends are everything to them. It's universal for the age, but they show it in different ways. For boys, the whole friendship thing is through technology and sports. Girls like to talk.

    Tweens are also a hot market. What do tweens consider cool? Music is at the top of the cool list, followed by going to the movies. "Being smart" comes third, tied with video games, followed by electronics, sports, fashion and protecting the environment, according to a report.

    Undoubtedly, tweens have great spending power in the United States. It was the tween market that made Justin Bieber and Harry Potter household names. Retailers(零售商) know tweens are a hot market for clothes, music and entertainment. Tweens have their own sense of fashion and enjoy their own parts of popular culture.

    Researchers have discovered the first Earth-sized planet. It was first marked by scientists' using NASA's Kepler telescope (望远镜), so it's called Kepler﹣186f. It lies about 500 light years from Earth and goes around its star. The planet is the right distance from its star for water: not too close or not too far. Water is one important condition that scientists guess is necessary for life. So it could have water and possible life. It's called a true Earth cousin.

    "This planet is an Earth cousin, not an Earth twin," said Barclay, who is among a team of scientists reporting on the discovery in the magazine Science this week.

    "It's very exciting to find a planet similar to the Earth," Barclay said. "It's not easy work because things change as we get more measurements."

    Scientists don't know anything about the air of Kepler-186f, but it will be a task for future telescopes which can study for chemicals that have something to do with life.

    "It's possible for life to live in this planet, but that doesn't mean there is life in it," Barclay said.

    So far, scientists have found nearly 1,800 planets in the universe.

    "The past year has seen a lot of progress in the search for Earthlike planets. Kepler﹣186f is very important because it is the first planet that is the same temperature and is almost the same size as Earth," scientist David Charbonneau wrote in an email.
