Recently I failed an exam. However, after I came out of my teacher's office, I told myself, "Smile! It's not so serious."

    I smiled a big smile and it worked a little, really.

Everyone gets frustrated sometimes. I used to be always influenced by {#blank#}1{#/blank#} (press) and I {#blank#}2{#/blank#} (be) often in low spirits. But one day I came {#blank#}3{#/blank#} a sentence in the Bible. "Do not be anxious about tomorrow, for tomorrow will be anxious for itself, let the day's own trouble be sufficient for the day." It suddenly struck me, "{#blank#}4{#/blank#} (worry) about a problem doesn't help. Why not just give a big smile and face up the trouble?"

    Now every time I want to cry, I remind myself that laughter is better than {#blank#}5{#/blank#} (tear) and anger. I{#blank#}6{#/blank#} (convince) that there's something magical about a smile. A smile helps me recover confidence and gives me the courage to move on.

    Remember, whenever {#blank#}7{#/blank#} (face) with a setback, whenever you've been treated {#blank#}8{#/blank#} (unfair),{#blank#}9{#/blank#} it takes is determination and you can feel happy again. Smile at life,{#blank#}10{#/blank#} it will shine on you.

    Last week, seven-year-old Charlotte Benjamin {#blank#}1{#/blank#} (become) a household name, and a hero to young girls everywhere, {#blank#}2{#/blank#} her handwritten letter to the LEGO company went public.

    In her letter, Charlotte complains about the lack of {#blank#}3{#/blank#} (diverse) in Lego characters. Here's what she wrote:

    "Dear Lego company,

    My name is Charlotte.

    Today I went to {#blank#}4{#/blank#} store and saw Legos in two sections — the girls' pink and the boys' blue. {#blank#}5{#/blank#} all the girls did was to sit at home, go to the beach, and shop, and they had no jobs but the boys went on adventures, worked, and even swam with sharks.

    I want you to make {#blank#}6{#/blank#} (many) Lego girl people and let them go on adventures and have fun, OK?

    Thank you.

    From Charlotte"

    Charlotte's dad loved her well-written letter {#blank#}7{#/blank#} much that he had it sent to the website, Sociological Images, which posted it to their Twitter account. The letter has been posted almost 2,500 times and {#blank#}8{#/blank#} (share) over 5,000 times on Facebook.

    Yesterday, LEGO responded to Charlotte {#blank#}9{#/blank#} (state) that they would include more female characters and themes, and that they have added new characters to the LEGO world {#blank#}10{#/blank#} (balance) the appeal of their themes.

    Ever wondered how many calories are in the human body? Or ever wondered why old people have {#blank#}1{#/blank#} (big) ears than they used to? The winners of Ig Nobel Prizes (搞笑诺贝尔奖) have got the answers.

    He Ig Nobel Prizes, founded in 1991, are to honor achievements {#blank#}2{#/blank#} first make people laugh, and then make them think, The ceremony {#blank#}3{#/blank#} (take) place at Harvard University every year. Winners' acceptance {#blank#}4{#/blank#}(speech) are limited to 60 seconds, {#blank#}5{#/blank#} (strict) policed by an eight-year-old girl.

    The honored research might seem ridiculous {#blank#}6{#/blank#} first sight, but that doesn't mean it lacks scientific value. For example, the research in 2006 on why dry spaghetti tends to break into more than two pieces was important {#blank#}7{#/blank#} (discover) failure in bridge spans (跨度) or human bones And a follow-up paper {#blank#}8{#/blank#} (publish) by MIT physicists several years later. But people are more likely to read about {#blank#}9{#/blank#} (break) spaghetti than to read an academic paper. Even when there is no immediate usefulness, {#blank#}10{#/blank#} is still good to encourage people to observe and think.
