最有意义的一件事 英语作文 150~200字左右，（高中水平）

一次有意义的经历(A meaningful experience)
On the second day of our middle exam, when I went to my classroom, I saw many
students were getting together. Feeling interested, I went over to see what was
happening. There, a boy was falling on his knees with tears in his eyes. Around
his neck he tied a board, on which was written that his sister had been burnt
and he needed money to cure his sister. Seeing this, I was moved and took out
all my money and gave it to him. He bowed to me, then many students donated
their money to him. Everyone hoped that her sister would be better soon.
That day we all felt excited, not only did we do a good deed, but also we
learnt how to make our life meaningful!

the important thing
In my life I experienced many things but one thing is my most unforgettable . One day I was on the way to school when suddenly I saw something lying on the ground . I went up to pick it up and found it was a wallet in which was much money. I had five minutes left and the class would begin in five minutes. What should I do? I had to go to school and handed it to the headmaster. and he praised me for that. I will never forget that day and that thing. So to me it is the most meaningful thing.
