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.

    Here is an astonishing and significant fact：Mental work alone can't make us tire. It sounds absurd．But a few years ago, scientists tried to find out how long the human brain could labor without reaching a stage of fatigue(疲劳). To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all!

    If we took a drop of blood from a day laborer, we would find it full of fatigue toxins (霉素) and fatigue products. But if we took blood from the brain of an Albert Einstein, it would show no fatigue toxins at the end of the day.

    So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours of effort as at the beginning. The brain is totally tireless. So what makes us tired?

    Some scientists declare that most of our fatigue comes from our mental and emotional (情绪的)attitudes. One of England's most outstanding scientists, J. A. Hadfield, says, “The greater part of the fatigue from which we suffer is of mental origin. In fact, fatigue of purely physical origin is rare. ”Dr. Brill, a famous American scientist, goes even further, He declares, “One hundred percent of the fatigue of sitting worker in good health is due to emotional problems.”

    What kinds of emotions make sitting workers tired? Joy? Satisfaction? No! A feeling of being bored, anger, anxiety, tenseness, worry, a feeling of not being appreciated— those are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.

    Astronauts on shorter shuttle missions（使命）often work very long days. Tasks are scheduled so tightly that break times are often used to finish the day's work.  This type of schedule is far too demanding for long missions on the International  Space Station（ISS）.  ISS crewmembers usually live in space for at least a quarter of a year. They work five days on and two days off to mimic the normal way they do things on Earth as much as possible . Weekends give the crew valuable.  Weekends give the crew valuable time to rest and do a few hours of  housework.  They can communicate with family and friends by email , internet phone and through Private video conferences.

    While astronauts cannot go to a baseball game or a movie in orbit, there are many familiar activities that they can still enjoy . Before a mission. The family and friends of each ISS crewmember put together a collection of family photos, messages, videos and reading material for

    The astronauts to look at when they will be floating 370 kilometers above the Earth.  During their mission, the crew also receives care packages with CDs, books, magazines, photos and letters . And as from early 2010, the internet became available on the ISS , giving astronauts the chance to do some “web surfing （冲浪）”in  their personal time.  Besides relaxing with these more common entertainments, astronauts can simply enjoy the experience of living in space.

    Many astronauts say that one of the most relaxing things to do in space is to look out the window and stare at the universe and the Earth's vast land mass and oceans.

    Some idiomatic phrases in English, often used in both spoken and written language, are very confusing! They don't even make sense when you first see them. However, using one of these phrases correctly when speaking or writing to an English speaker is very impressive and shows that you are comfortable with the language. Here are some wonderful and interesting British idioms. Use them wisely.

    When pigs fly!

This expression is one of my favorites and I use it all the time. It is used primarily when speaking, meaning that something is extremely unlikely or impossible. For example, "I will forgive him when pigs fly!" "When do you think you will get a gym membership, Lucy?" "When pigs fly!"

    A penny for your thoughts?

This question is used in a situation where someone appears thoughtful or is very quiet seeming lost in thought. But remember that you don't actually have to pay them a penny if they do tell you what is going on! For example, "You've been a bit quiet this evening, Pete. A penny for your thoughts?"

    It's the bee's knees

The phrase dates back to the 1920s, and refers to an extraordinary person, thing, idea, and so on. For example, "Try this chocolate. It's the bee's knees."

    To feel a bit under the weather

    I use this expression in many different situations but most use it to refer to feeling ill, or unwell. You would not use this phrase if you were feeling extremely unwell. It is only for those times when you are feeling a little ill or suffering from something slightly like a cold or a cough. However, this can also be used to refer to feeling emotionally low.

    Johnny Jennings is 86 years old, but he first visited the Georgia Baptist Children's Home when he was 18, and the visit changed his life forever.

    A child ran up to Jennings, begging to be adopted, and it was at that moment that Jennings realized his life's mission. From that day forward, Jennings did everything he could to help, and that turned out to be quite a lot. Since he wasn't ready to adopt a child of his own, he decided to contribute financially. Since he wasn't wealthy, he did so by collecting paper and aluminum (铝) products and cashing them in for money. That may not sound like it would amount to much, but Jennings has donated more than US$400,000 over the past 30 years. That's a lot of paper products.

    Over those 30 years Jennings has become a cornerstone of the children's home.

But how does he get all that paper? Now that people know about his efforts, the paper pretty much comes to him. People drop it off at his house after collecting it through churches, organizations or in their own lives. Jennings also collected pennies, and as they say: A penny saved is a penny earned. Well, he's saved 24 miles' worth of pennies. It's the truth. "84,480 is a mile of pennies," Jennings said. "We finished 24 miles. We had most people from church collecting pennies." Each and every mile was a donation to the church.

    One of Jennings' favorite events is the church's annual meeting, which is when he presents his check each year. During this time, the kids who live in the children's home are also in attendance and he loves the opportunity to spend time with them. Jennings has served on the board for 45-year terms. "I've been a trustee for 20 years," Jennings said. "I'm just part of the family." And what a special family it is, thanks in large part to Johnny Jennings.

    You may probably meet most of the powerful graduation speakers, here who are well-known people in their fields. I think the schools couldn't have picked better speakers than them, because they set good examples, deeply inspiring us in our daily life.

    1) Steve Jobs, Stanford University:

    "Remembering you're going to die, and the best way I know is to avoid the trap of thinking that you have something to lose. There is no reason not to follow your heart. Your time is limited, so don't waste it living someone else's life. Don't let the noise of others' opinions drown out your own inner voice... "

    2) Oprah Winfrey, Stanford University:

    "I consider the world, this Earth, to be like a school... And the secret I've learned to get ahead is being open to the lessons from the grandest universe of all. Don't react against a bad situation. And the solution will arise from the challenge. So don't give up easily, acting with responsibility... "

    3) Bono, University of Pennsylvania:

    "For four years you've been buying, trading, and selling everything you've got in this market-place of ideas. Your pockets are full, even if your parents' are empty, and now you've got to figure out what to spend it on... The world is more flexible than you think and it's waiting for you to hammer it into shape... "

    4) Michael Dell, University of Texas at Austin:

    "Now it's time for you to move on to what's next and obtain your desire. But you must not let anything prevent you from taking those first steps. Don't spend so much time trying to choose the perfect opportunity, or sometimes you'll miss the right opportunity. Recognize that there will be failures and obstacles. But you will learn from your mistakes and the mistakes of others."
