A Piece of Good News 一个好消息

Today is a good day, because I hear a piece of good news. A week ago, our class went to the cinema to watch a movie under the lead of our Chinese teacher.by accident, we took up our math class. So our math teacher said that class would be made up on this weekend. But today she tells us that we don’t need to make up classes anymore, because of several reasons. Isn’t a good piece of news?
今天是个好日子，因为我听到一个好消息。一周前，语文老师带我们班去电影院看电影，因为一些意外我们把数学课给占用了。我们的数学老师这周末要把课补回来。不过今天她告诉我们再也不用补这个课了因为一些原因。难道这不是个好消息吗？
