Some problems are difficult to solve in our life. However, there are a lot of number expressions （表达用语） that can help. Today, let me show you some examples.
Sometimes we can "Kill two birds with one stone". That is to say, we can complete two goals （目标） with only one effort or action. But we must remember that "two wrongs don't make a right". If someone does something bad to you, you should not do the same to him.
When I was a young child in school, my favourite subject was Maths. My teacher used to "give me three cheers" when I did well in Maths, praising （赞扬） my hard work and good grades.
When I was in high school, some of my friends once had trouble doing their schoolwork. In fact, they did not care if they could finish high school. But it seemed that they really got a surprise when they completed their studies and graduated （毕业） from high school. They were "on cloud nine".
"Nine times out of ten", students who do well in school often find good jobs. Some people work in an office doing the same things every day at nine-to-five jobs. However, it's good to know that happiness at work isn't just about money.
