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.

How Room Designs Affect Our Work and Feelings

    Architects have long had the feeling that the places we live in can affect our thoughts, feelings and behaviors. But now scientists are giving this feeling an empirical(经验的，实证的) basis. They are discovering how to design spaces that promote creativity, keep people focused and lead to relaxation.

    Researches show that aspects of the physical environment can influence creativity. In 2007, Joan Meyers-Levy at the University of Minnesota, reported that the height of a room's ceiling affects how people think. Her research indicates that higher ceilings encourage people to think more freely, which may lead them to make more abstract connections. Low ceilings, on the other hand, may inspire a more detailed outlook.

    In additions to ceiling height, the view afforded by a building may influence an occupant's ability to concentrate. Nancy Wells and her colleagues at Cornell University found in their study that kids who experienced the greatest increase in greenness as a result of a family move made the most gains on a standard test of attention.

    Using nature to improve focus of attention ought to pay off academically, and it seems to, according to a study led by C. Kenneth Tanner, head of the School Design & Planning Laboratory at the University of Georgia. Tanner and his team found that students in classrooms with unblocked views of at least 50 feet outside the window had higher scores on tests of vocabulary, language arts and maths than did students whose classrooms primarily overlooked roads and parking lots.

    Recent study on room lighting design suggests than dim(暗淡的) light helps people to loosen up. If that is true generally, keeping the light low during dinner or at parties could increase relaxation. Researchers of Harvard Medical School also discovered that furniture with rounded edges could help visitors relax.

    So far scientists have focused mainly on public buildings. "We have a very limited number of studies, so we're almost looking at the problem through a straw(吸管)," architect David Allison says. "How do you take answers to very specific questions and make broad, generalized use of them? That's what we're all struggling with."

    There was a gardener who looked after his garden with great care. To water his flowers, he used two buckets（桶）. One was a shiny and new bucket. The other was a very old and dilapidated one, which had seen many years of service, but was now past its best.

    Every morning, the gardener would fill up the two buckets. Then he would carry them along the path, one on each side, to the flowerbeds. The new bucket was very proud of itself. It could carry a full bucket of water without a single drop spilled（溢出）.The old bucket felt very ashamed because of its holes: before it reached the flowerbeds, much water had leaked along the path.

    Sometimes the new bucket would say, "See how capable I am! How good it is that the gardener has me to water the flowers every day! I don't know why he still bothers with you. What a waste of space you are!"

    And all that the old bucket could say was, "I know I'm not very useful, but I can only do my best. I'm happy that the gardener still finds a little bit of use in me, at least. "

    One day, the gardener heard that kind of conversation. After watering the flowers as usual, he said, "You both have done your work very well. Now I am going to carry you back. I want you to look carefully along the path. "

    Then the two buckets did so. All along the path, they noticed, on the side where the new bucket was carried, there was just bare（光秃秃的）earth；on the other side where the old bucket was carried, there was a joyous row of wild flowers, leading all the way to the garden.

    Most people agree that eating healthy food is important. But sometimes making good food choices can be difficult. Now, there are apps that can help people learn about the food they eat to improve their health and their dining out experience.

    Open Table app

    Open Table app helps people choose restaurants when they want to go out to eat. It is a free service that shows users restaurant available based on where and when they want to dine. It gives users points when they make reservations(预定), which can add up to discounts on restaurant visits.

    Max McCalman's Cheese&Wine Pairing app

    Wine and cheese can be a great combination. But which wines go best with which cheeses? Max McCalman's Cheese&Wine Pairing app can help. It provides information about hundreds of different cheeses and suggests wines to pair with each. Max McCalman's Cheese&Wine Pairing app is free.

    HappyCow app

Vegetarians do not eat animal meat. Vegans do not eat any animal products. The HappyCow app is made for both groups. Users can search for vegetarian-vegan restaurants and stores around the world.

    LocalEats app

    Restaurant chains, like McDonalds, can be found almost anywhere a person might travel. But sometimes travelers want to eat like locals. The LocalEats app is designed for that. It can help you find local restaurants in major cities in the US and in other countries. It costs about a dollar.

    Where Chefs Eat app

    "Where Chefs Eat" is a 975-pagc book. Most people would not want to carry that around. But there is a much lighter app version of the same name for just $15. Six hundred chefs provide information on 3,000 restaurants around the world on the Where Chefs Eat app.
