Being mature doesn’t mean the person is adult. The age is not the standard to measure whether a person is mature or not. Some teenagers know their future duty and act in a mature way. The symbol of being mature is not decided by age, but the way they think.
成人并不意味着成熟。年龄并不是衡量一个人是否成熟的标准。一些青少年知道他们将来的责任，会表现得比较成熟。成熟的标志不是由年龄决定的，而是我们思考的方式。

Firstly, the mature person must have right attitude towards life. When he gets the unfair treatment, he won’t be angry and give up on himself, instead, he can adjust himself and get used to the new environment. So, no matter what happens to him, nothing can frustrate him. He always finds his own way to appreciate the beauty of life.
首先，成熟的人一定会有正确的生活态度。当他遇到不公平待遇的时候，他不会生气，放弃自己，相反，他会自我调整，适应新环境。所以无论发生什么事都不会让他沮丧，他总是能够用自己的方式去欣赏生活美。

Secondly, the mature person must be knowledgable. As he experiences so much,  he has broadened his vision. When other people ask him  questions, he can give his own opinion and his profound thoughts will impress others. When we talk to the mature people, we will always learn something from them. 
第二，成熟的人一定是知识渊博的。由于阅历丰富，所以也开阔了视野。当别人问他问题时，他可以给出自己的见解，深远的想法会给他人留下深刻印象。我们跟成熟的人交流时总会从他们身上学到东西。

People like to communicate with mature minds, because it helps them to grow up. Everybody can be mature if they improve themselves all the time.
人们喜欢与成熟的人交流，因为这样能帮助他们成长。如果不断提升自我，每个人都可以变成熟。
