我是一个细心的孩子。每次做数学题，我都一题一题地做，每次数学考试我都是100分，老师表扬了我。
I am a careful child. Every time I do a math problem, I do it one by one. Every time I do a math test, I get 100 points. The teacher praised me.
有一次，我们又要考试了。有一题我做错了，通过我那细心的检查，总算做对了。
Once, we had another exam. There is a problem I did wrong, through my careful inspection, finally did right.
然后，我又考了100分。
Then I got another 100.
