     As the sun rose, a dewdrop (露珠) woke up.  There it sat on a leaf, catching the sunlight. Proud of its

simple beauty,  it was very happy.  Around it were other dewdrops,  some on the same leaf and some on

other leaves. The dewdrop was sure that it was the best, the most special dewdrop of them all.

     Ah, it was good to be a dewdrop.

     The  wind  blew  and  the plant began to shake,  tipping  (使倾斜)  the leaf . The  dewdrop  became

frightened as it started to move towards the edge (边缘)of the leaf. Why was this happening? Things were comfortable. Things were safe. Why did they have to change? Why? Why?

     The dewdrop  reached  the edge of th e leaf.  It was sure that this was the end.  The day had only just

begun and the end had come so quickly. It seemed so unfair. It seemed so meaningless. It tried hard to do whatever it could to stay on the leaf, but it was no use.

     Finally, it fell. Below there was a mirror. A reflection of the dewdrop seemed to be coming up to meet

it.  Closer and closer they came together until finally.., the small dewdrop became a part of the great pond (池塘). Now the dewdrop was no more, but it was not destroyed.
