①Last year I spent my whole winter vacation in the US with my host family. The most unforgettable experience I had there was joining the Boy Scouts (童子军) of America. It was there that I got to face a great challenge: camping in the rain.

    ②One Saturday, we went hiking in the rain for more than six hours. When we finally reached the camping site, my shoes, my clothes, my bag and all the things inside it were totally soaked.

    ③Then, an even worse thing happened. Our guide teacher stepped out and said: “Today's hiking is a test. We're not going back home tonight! We have to live here tonight!” Soon we began to accept the truth and went to work. We just covered ourselves with a kind of plastic sheet and lay down by the campfire. While sleeping, I woke up several times. But to my surprise, I adapted (适应) to the environment quickly. Many others didn't even fall asleep.

    ④The sun finally rose and our hope returned. The bus came at 6 am and sent us back to our lovely home.

    ⑤Many in China say that children in the US were born with an adventurous spirit. But I think they were born with nothing different. Instead, they make differences by facing troubles positively. The camping adventure was a gift they gave themselves. Many Chinese children are over-protected when they are growing up. Therefore, when facing troubles, how can it be possible for us to react positively?

    Once upon a time, there was a tree which wanted to become a treasure box. One day, a farmer cut it down and sold it to a carpenter(木匠). The tree was happy because he thought the carpenter would make it into a treasure box.

    To its surprise, the carpenter made it into a feed box for animals. The tree felt very disappointed because that was not its dream. Several years later, the feed box was thrown away. Someone picked it up and placed it into an old temple. The tree forgot its dream little by little.

    One day, a couple came to the temple. The woman gave birth to a baby boy. There wasn't a bed in the temple. So they placed the baby in the feed box. They loved him and regarded him as their treasure. The tree suddenly realized that it became a real "treasure box" at that time.

    Sometimes you may think your dream will not come true. Don't forget your dream. It may be realized in another new way.

    Born without arms or legs, Nick Vujicic knew from an early age that he was different. There is no medical explanation for Vujicic's physical disability. Though he struggles (挣扎) with some little things of everyday living (brushing teeth, for example), he has become a great speaker.

    Confidence didn't come naturally to Vujicic. Growing up in Melbourne, Australia, he struggled with depression (抑郁)and was bullied （欺凌）at school. When he was just 10 years old, he tried to kill himself. Thanks to his family's strong support and selfless love over time, Vujicic chose to be positive towards life. After his mother showed him a newspaper article about a man dealing with a serious disability when he was seventeen, he started to give public talks. The great Australian has visited more than 50 countries and given thousands of talks. No matter where he goes, he communicates the main message﹣that no matter what difficulties you meet, you can overcome ! Here's what he said in one of his powerful speeches：

    "I felt like I was a burden (负担)to those around me and the sooner I go, the better it'd be for everyone. I wanted to end my pain and end my life at a young age, but I am thankful once again, for my parents and family who were always there to comfort me and give me courage.

    Because of my emotional struggles I had experienced with bullying and loneliness, God has given me a passion (激情)of sharing my story and experiences to help others deal with whatever difficulty they have in their life and let God turn it into a blessing. To encourage and inspire others to live to their fullest potential and not let anything get in the way of achieving their hopes and dreams."

What are some of the difficulties of being blind? Two hundred years ago, a little boy was born in France. He was Louis Braille, a happy and lovely baby.

Sadly, when he was three, something bad happened. While playing in his father's shop, Louis hurt his eyes on a sharp thing. Although he got the best care at that time, he was still completely blind and could not see all the lovely colours and beautiful things around him.

Louis was a kind boy. As he grew older, he wanted to help other blind people read. However, it was really hard for him. The first way he tried was to poke (戳) holes in paper and read by touching raised (凸起的) letters with his fingers. But it was too slow to read the letters and few blind people could do it well. After that, he tried many other ways.

One day, Louis heard about someone using dots to represent (代表) sounds. He immediately found its advantages and he spent three years improving upon this idea. Finally, he made a special alphabet and blind people could feel it with their fingers. Each letter was made with a number of dots and people could feel them by their fingers.

The alphabet that Louis made is called 'Braille'. Today many blind people use 'Braille' to help them to read. This is how the Braille Alphabet looks:
