短文改错。

     It was my 18th birthday yesterday. As the age is special for our teenagers, so my parents held a

birthday party for me at home. With my parents and some of my good friends attend my birthday party,

I really had unforgettable experience. We sang songs, dancing and played games together. We all

enjoyed ourselves very much. During the party, my parent told me that from then on I was no longer a

child and an adult. They also said I should be more independent and responsibly. Hearing their words, I

was greatly encouraged. It was just in that moment when I felt I was a grown-up.3
