Describe a person who made you laugh happily when you were a child
You should say:
Who this person is
What this person did to make you laugh
Why this person made you laugh
And how you felt about it
My childhood witnessed lots of moments of happiness (我的童年充满了喜悦的瞬间，witness 见证), one of which was a part-time magician at the community theme park being the very person who brought me the most genuine laughter.
As I can recall(在我的记忆中), he always dressed smart(穿着正式), with a black top hat, colorful suit and a big smile on his face when he greeted every kid passing by and performed magic tricks for them.
He impressed me the most on one of mybirthdays, when my parents took me to the theme park to celebrate.
No sooner than he was informedby the kids around that it was my birthday than he approached me with a warm smile and handed me his magic black hat.
(No sooner than (倒装，他一了解到那天是我的生日，就带着温暖的微笑走向我，并递给我他的黑色礼帽) In a mysterious tone, he instructed me to say a secret word to the hat and promised to work magic for the “birthday princess”.
Not only was I entertained by his hilarious gestures and funny birthday songs, I was also amazed at the fact that his birthday gift,namely a princess crown, came out of the black hat at the blink of an eye. (not only, (but) also 我不仅因为他滑稽的姿势和搞笑的歌声忍俊不禁，更是被他一眨眼功夫从黑色礼帽中变出的生日礼物—— 一顶小王冠——而深深吸引)。
As an innocent child, I firmly believed that this little crown was magical, a secret power with which I could relive the exhilaration and excitement (非限定性定语从句，一种神秘的力量，能够让我重温观看他表演的兴奋与激动) brought by the kind magician and his entertaining performances.
For those toddlers like me, who for a briefmoment lived in a magic wonderland, he was completely awe-inspiring.
His rich imagination,together with his amiable personality enriched our childhood memories.
