I can well remember that I was once asked to deliver a speech titled “A Real Test in My Life” before the whole class     1     the age of 9! You can imagine how     2     (terrible) shy I was with so many eyes fixed on me. I had no choice but     3     (prepare) for it, though.

But the hardest part     5     (lie) in my oral presentation from my memory, because it     6     (forbid) to read from the paper. The real moment began when I stood on the platform with my legs     7     (tremble) and my mind blank. But my listeners were waiting patiently without any signs of rushing me. Gradually I found     8     (I) back, delivering my speech without difficulty. After what seemed to be a hundred years, I found my audience applauding — I made it! From then on, my fear of talking before the audience disappeared. Actually with my     9     (confident) built up, I now turn out to be a great speaker. Looking back, I know the     10     (great) difficulty on my way to success is my fear. Overcome it and I will be able to achieve my goals.

So I think a clown doctor can help people by entertaining them.

    6    (wear) a white coat, my curly rainbow wig and a big red nose, I walk into the waiting area, where there is a familiar atmosphere of     7    (bore) and tension. There, I spot a little girl called Lara whose ankle has got injured and is twice its normal size. The doctors and nurses are treating her injury. To get her attention, I begin to do a magic trick,     8     has made her scared and anxious look replaced with loud laughter. Seeing their daughter so much happier has in turn made Lara’s parents more     9     (relax).

I hope clown doctors can help make the hospital a friendlier place to visit. After all, it really is true that “laughter is the    10     (good)medicine”．
