　　A young American doctor is sleeping when suddenly his doorbell begins to ring. It is midnight now, but what could the doctor do? He should get up, put on his coat and go downstairs(下楼).

　　When he opens the door, he sees a man standing with a hat in his hand. “Can you come at once to a place out of town? I can show you the way.” The man says. “Certainly.” says the doctor. After a few minutes the car is standing at the front door.

　　They are driving on for a long time. Then the man says, “Here we are. This is my home. Now I can pay you and you can go back to town.”

　　“What?” The doctor asks.

　　“You see, there are no taxis at this time of the night, but a doctor often makes night calls, so excuse me. Here is your money. Thank you, doctor. Good night.”

1．What does the man ask the doctor to do?

2．Ts the man ill?

3．Is the doctor happy at last?

In the past, people who graduated from college felt proud of their academic(学业的) achievements and felt confident that their degree（学位）would help them to find a good job.

However, in the past four years the job market has changed greatly. This year’s college graduates are facing one of the worst job markets. For example, Ryan Stewart, a graduate of San Jose State University, got a degree in religious（宗教）studies, but no job prospects. He points out that many people already working are getting laid off（解雇） and don’t have jobs, so it’s even harder for new college graduates to find jobs.

Four years ago, the future looked bright for the class of 2006. There were many high-tech job chances. Graduates received many job offers, and they were able to get jobs with high salaries（薪水）and benefits such as insurance(保险) and paid vacations. However, "Times have changed and it's a new market," according to an officer of the San Jose State Career Center.

The officer says students who do find jobs started preparing two years ago. They worked during summer vacations, they have had several short-time jobs, and they’ve majored in one of the few fields that are still hot, like chemical engineering, accounting, or nursing, where average（平均的）starting salaries have actually increased over last year. Other popular fields (like information system management, computer science, and political science) have seen big declines(下降) in starting salaries.

Ryan Stewart (he had hoped to become a teacher) may go back to school in order to become a college teacher. He thinks college teaching could be a good career even in a bad economy.

In conclusion, these days a degree may not be a ticket to instant wealth for some students. For now, they can only hope the value of their degree will increase over time.
