我终于做出了这道题

最后一节课，老师安排我们做书上的几道题，我快要做完了，还剩最后一道题了，这道题是“9*9=”。我苦思苦想，着急的说：“快要放学了，这道题怎么做？好难，好难，我实在做不出来了。”我想，反正做不出来，回家之后再想呗！老师好象看穿了我的心思，说：“写完的可以放学，没写完的不可以放学。”眼看同学们一个个地放学回家，教室里就剩我和老师了，只有好好想了，过了几分钟，我一拍桌子，说：“我做出来了，九乘九等于八十一！”

In the last class, the teacher arranged us to do several questions in the book. I was about to finish it. There was the last one left, which was "9 * 9 =". I thought hard and said anxiously: "it's going to be school, how to do this problem? It's so hard. I can't do it. " I think I can't do it anyway. I'll think about it after I go home! The teacher seemed to see through my mind and said, "you can leave school if you have finished writing. You can't leave school if you haven't finished writing." Seeing the students come home from school one by one, there is only me and the teacher left in the classroom. After a few minutes, I clapped the table and said, "I made it. Nine times nine is eighty-one!"

我真高兴终于做出了这道题。

I'm glad to have finally worked out the problem.
