In this day and age,it may seem that getting two people with different views together to discuss them leads to a disaster.Just think about what would happen if you sat down and had an open and honest conversation with someone with completely opposing views.Could it bring you closer together?

    However,the Human Library Organization is counting on it.At a Human Library,people volunteer to become "books" and make their experiences open and available."Readers" are encouraged to ask them questions freely,and they'll get honest answers in return.There's no judgment,and no questions are off—limits.

    You won't find unpleasant comments,and you won't lose faith in humanity.At the Human Library,you actually feel letter about the world you live in.You might even make a new friend!

    "The human books consist of people who have been discriminated by society."said Ronni Abergel,the Human Library Organization's founder,who has set out to build a space for conversations that can challenge prejudices through dialogue."The most pleasantly surprising thing about it is how close all the human books become to one another."she said.

    Human Libraries help to remind us there really is more that unites us than divides us.And as events now spread throughout 82 countries,with Human Libraries even set to launch soon in Pakistan and Jordan,you can tell that is a shared feeling.

    "We can spend billions and billions in trying to build up homeland security and our safety,but real safety comes from having positive relations to other groups in your community."said Abergel,"Real safety is not going to come from building walls.It's going to come from reaching out and getting to know each other."

    It's 5:00 in the morning when the alarm rings in my ears. I roll out of bed and walk blindly through the dark into the bathroom. I turn on the light and put on my glasses. The house is still as I walk downstairs while my husband and three kids sleep peacefully. Usually I go for a long run, but today I choose my favorite exercise DVD. Insanity. Sweat pours down my face and into my eyes. My heart races as I face my body to finish each movement. As I near the end of the exercise, I feel extremely tired, but a smile is on my face. It's not a smile because the DVD is over, but a smile of success from pushing my body to its extreme limit.

    Some people enjoy shopping, smoking, food, work, or even chocolate. But I need exercise to get through each day. Some shake heads when they see me run through the town. Others get hurt when I refuse to try just one bite of their grandmother's chocolate cake. They raise their eyebrows, surprised by my “no thank you,” or by my choice to have a salad. Over the years , I have learned it's okay to just say “no.” I shouldn't feel sorry for refusing food that I don't want to eat.

    So what drives me to roll out of bed at 5:00 a.m.? What gives me the reason to just say no to ice cream? Commitment. A commitment to change my life with a way that reduces daily anxiety, increases self –confidence and energy, extends life and above all improves my body shape. This is the point where a smile appears on my face as I look at myself in the mirror or try on my favorite pair of jeans that now fit just right. It's through commitment and sweat that I can make a difference within myself inside and out.

    On a clear night, you can see a sky paced with stars. But you can't see planets orbiting any of these stars, even with the strongest Earth—based telescopes. Astronomers reported that they discovered seven Earth—sized planets orbiting a nearby star called TRAPPIST – 1 in February. They had to rely on indirect evidence to tell them that the planets are there. By doing some math, they figured out the number of planets and the distance of their orbits.

    TRAPPIST – 1 is a red dwarf （红矮星）, much smaller than our sun, but larger than Jupiter (木星). If the sun were the size of a basketball, TRAPPIST – 1would be the size of a gold ball. This star is one of our closest neighbors, just like the moon to the earth in space.

    When astronomers using Earth-based telescopes to study TRAPPIST – 1,they noticed that every once in a while, it became slightly dim（昏暗）. They decided that a planet must be passing in front of the star, blocking part of the light. This dimming would come and go as the planet orbited the star, passing alternately (交替地) behind and in front of the star regularly.

    By making careful observations, astronomers expected to get a rough idea of the planet's size from the pattern of dimming light. But the light level changed often and not at evenly spaced (均匀间隔的) times. The astronomers had to conclude they were looking at more than one planet! To get additional data, NASA's spritzer Space Telescope measured TRAPPIST –1's brightness nearly continuously for 20 days, catching 34 crossings of planets in front of the star. Sorting through the mess of data, the astronomers found that the innermost planet completes its orbit in 1.5 Earth days, while the outermost planet takes 20 days. Once you know how long it takes each planet to complete an orbit, you can work out how far it is from the star compared with the other planets.

    The TRAPPIST – 1 planets are not alone. So far, astronomers have found more than 3,400 planets that orbit other stars.

    Canada is a very large country. It is the second largest country in the world. By contrast(比较)it has a very small population. There are only about 29 million people (by the year 1996) there. Most Canadians are of British or French origin, and French is an official language of Canada as well as English. About 45% of the people are of British origin, that is, they or their parents or grandparent, etc., come from Britain. Nearly 30% are of French origin. Most of the French-Canadians live in the province of Quebec.

    Over the years, people have come to live in Canada from many countries in the world. They are from most European countries and also from China, besides other Asian countries.

    However, Canada was not an empty country when the Europeans began to arrive. Canadian Indians lived along the coast, by the rivers and lakes and in forests. Today there are only about 350,000 Indians in the whole country, with their own languages. In the far north live the Inuit. There are only 27,000 Canadian-Inuit. Their life is hard in such a harsh climate.

    I think that a great friend is like a great artist who can change my feeling about life greatly. When I talk about the person who influenced(影响) me most. I must think of my best friend quickly.

    When I was in my university, one of my classmates sat beside me. His name is Wang Tao. He is my unforgettable friend in my life. He is good at study and handsome. Everyone knows that he is a genius(天才) of my university. Besides, he is kind-hearted and is always ready to help others.

    I remembered that my maths was poor at that time, but he was excellent in solving(解决) maths questions. He often got high scores. Since we talked all day long, he was patient and polite to answer my maths questions. Slowly, I made great progress. I passed the examination finally. Then we became friends naturally.

    We know that we live in a society, so we need a lot of friends. There are two kinds of friends, good and bad, bad friend may make our life failed, while good ones make our life successful. To me, Wang Tao is a very good friend. I learned so many lessons from him, and I became more and more excellent.

    We separated three months ago. Now I miss him very much, and I hope that our friendship will continue to be just as strong after we graduate.

    Actors Keira Knightley and Kristen Bell have both commented on their worries about using Disney princesses as role models for their children.

    On a famous talk show, Knightley said her daughter (who was born in 2015) was "banned" from watching Cinderella, which Disney produced as a cartoon in 1950 and a live-action film in 2015. "Cinderella waits around for a rich guy to rescue her. Don't. Rescue yourself! Obviously."

    Knightley added that she had also forbidden The Little Mermaid, the 1989 cartoon. "This is the one that I'm quite annoyed about because I really like the film. I mean, the songs are great, but do not give up your voice for a man. Well, that's a little difficult to handle, but I'm keeping to it."

    Bell, the star of Frozen, expressed her disapproval of the Snow White fairytale, which became a classic Disney cartoon in 1938. In an interview with parents, Bell said: "I look at my girls and ask, ‘Don't you think it's very unusual that Snow White didn't ask the old witch why she needed to eat the apple? Or where she got that apple?' I say, 'I would never take food from a stranger, would you?' And my kids respond, 'No!' And I think I'm doing something right."

    Bell, who played a Disney princess in Frozen, said she also used the story to illustrate issues about permission. She says that she asked her children: "Don't you think that it's very strange that the prince kisses Snow White without her permission? … Because you cannot kiss someone if they're sleeping!"

    Bell later responded to criticism on social media. To one user she wrote: "Everything is a message to our children, because they are sponges(海绵) that soak up everything and are learning how to be adults through what they see. I want my girls to see and practice critical thinking and respectful behavior."
