    问答题
    ◆Topic 10：Work to Live or Live to Work?　　Questions for reference:　　1) Why do people live?　　2) Are people really aware of the reasons why they work?　　3) How do you balance work and life?

    正确答案： 【参考答案】
    Living in a highly competitive society, the idea that the purpose of life is to work is prevalent even dominant. Most bread earners believe that financial guarantee is more realistic and more important for a person and for his family. So they take for granted that devoting to work is the most reasonable and worthy thing to do.
    Nevertheless, objectors think that work is only a means to have a better life. They argue that there are more important things than work in life, such as friends, personal interests, social responsibilities and so or. They think that life will be dull and meaningless with work as its aim.
    In my opinion, we should strike a balance between work and life. On the one hand, to be a diligent worker is necessary and meaningful. On the other hand, we should not be workaholic, or we will lose many significant things in life, such as love and friendship.

I’ve known him for 4 years and I wish we could be colleagues again someday.
