     It is commonly believed that most people go to work to make money. However, it has been said that

today people earn money to go to work. The difference between making money and going to work

suggested by this is important.

     Would you give up your job if you had a lot of money? In a 2010 poll(民意测验) conducted by the

Gallup Organization, quite a few people conducted among said they would do so, but researchers find that work is one of life's main satisfactions for many people.

     Take Liu Yan, 23, a former teacher, for example, before she quit her job in 2010, she taught at a high

school. Although the salary was of the ordinary, she liked her job and worked so successfully that in only

one year's time after her graduation from college. She not only won a prize for excellence in teaching, but

also enjoyed wide popularity among her students. In her second teaching year, however, she met a

millionaire and got married; and went to live in Hong Kong with her husband. There she led a very

comfortable and easy life, spending most of her days doing shopping and going traveling. After one year of endless vacation, though, she began to miss her work and asked for return to her teaching position. "I'm so tired of this kind of life," she explained in her letter to the school she had previously worked for, "that I miss more than ever the days with my students."

     So what do you think of it? Which is more important: work or money?

One more question, if there are two jobs, the one offers good salary with little challenge, just like work in

the government department; the other, a lot of challenge but low salary, what's your choice?
