Last weekend, Lucy, Mary and I didn't (live / stay) at home. We had a very
(busy / sad) weekend. We all (went / go) to a community with a lot of old people. We helped some grandfathers and grandmothers. Especially Grandpa Liu, he was 88 years old. We went there by bus and got to (her / his) house at nine o'clock in the morning. As soon as we got (there / here), we helped him to do some housework. First, I cleaned his rooms. Then Lucy washed the clothes for him. Mary (watered / cleaned) some flowers and they were very beautiful. Finally, we cleaned the windows and doors. We finished these
(thing / things) at twelve o'clock and we made some delicious food for Grandpa Liu, he was very happy and (thanks / thanked) us.
It was a busy weekend, (but / because) I thought it was also a meaningful(有意义的) weekend for us. We need (help / to help) those who really need help.
