帮我评价一下下面的短文.

i went to the film yesterday.it took me 10 minutes to wait for the bus.after i got on the bus,i saw an old woman aboard the bus.i offerd my seat to her.she smiled and said "Thank you"to me.i answerd "that's all right." about 12 minutes later,i got off.i waved my hands and said "goodbye" to the old lady.i was so glad that i can help others.then i went to the film.
was 属于be 动词,不能和go这个实义动词一起用.
yesterday 前面不用加on
事情发生在过去,全文都要用过去式
it take or took sb sometime to do sth
the bus was comed 的意思是汽车被来到
让座是offer one's seat to sb或者是give up one's seat to sb.
一定要注重时态!
祝你英语越学越好^^
