求英语作文,my unforgetful experience(一次难忘的经历）老师要求160个单词以上，

It was an exciting experience for me and my classmates last Saturday.It was fine that day.In the afternoon,we went to the park and helped the dustman there clean the park.Although we were very tired after work,we felt very happy to see that the park was very clean.I think we should have more chance like that to go out and help the other people.We wish to do more things to preserve our environment. You see,with our work in the park,the park is now a good place to relax for people after work and study. We need more places like this.And everybody knows that a good environment depends on everybody.

An Unforgetful Experience in the Great Wall
It was a sunny day yesterday ,and it was Sunday .My parents and I paid a visit to the Great Wall.We start out at 8 in the moring,and we got there at 9:30.When we were at the bottom of it,we saw a crowd of people there.Boys and girls ,young and old ,men and women were everywhere.We were all excited and began to climb it.We followed the steps ,walking towards the top of the Great Wall.Wow!What a nice view!The sun was shining ,the wind was blowing ,and the small hills are connected to each other .The great Wall lies on the earth ,just like a huge long dragon.Soon we reached to the top of the Great Wall.Everything seemed to be under us.We were wild with joy and couldn't help shouting out!
That was a great trip which we can't forget!
