Mr. Lee was in bed and was trying to go to sleep when he heard the bell ring. He turned on the light and looked at his clock. It was twelve o'clock. "Who can it be at this time of night?” He thought. He decided to go and find out. So he got up, put on his dressing gown(长袍) and went to the door. When he opened the door, there was nobody there. "That is very strange." Then he went back to his bedroom, took off his dressing gown, got back into bed, turned off the light and tried to go to sleep.

    A few minutes later he heard the bell ring again. Mr. Lee jumped out of bed very quickly and rushed to the door. He opened it, but again he found no one there. He closed the door and tried not to feel angry. Then he saw a piece of paper on the floor. He picked it up. There were some words on it: “It is now after midnight, so it is April Fool's Day. April fool to you!”

    “Oh, it was the English boy next door!" Mr. Lee exclaimed(惊叫) and almost smiled. He went back to bed and fell asleep at once. The bell did not ring again.

    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. "
