用My weekend 写作文.用过去式写的.如题
答案
I had a sad weekend last week. I wanted to sing songs with my sister but she was very busy. Then I wanted to swim with my friends, when we got to the swimming pool, it was closed. We had to go to a very small swimming pool and put ourselves in the dirty and dark water. Then in the afternoon, when we walked out of the swimming pool, we found all our money was gone. We didn't have money to go home by bus, we had to walked back home for 10 miles. At last when i arrived at home, i found my key was at home and i had to sit outside my home the whole night. I hope next weekend, i can do better.
