During his freshman year summer vacation, his classmate got him a job working on a hay (干草) farm. He threw hay up into wagons as the tractor drove around fields, and then they stacked (剁起) it in the hot barn. It was a hot，low­paying job.

He once worked a few nights a week at a grocery store. He put things on the shelf. It was a lot of lifting and carrying，and his arms were strong from this and the previous job. It was dull and didn’t pay much.

He took some time off when soccer got serious，but the following summer he tried working at a lumber yard. It was hot outside, but he got a lot of exercise lifting and carrying things like boards and drywall. He also learned a lot about building supplies. It still didn’t pay well.

From there, he spent a year doing some tutoring for a friend of the family, but that was piecemeal. His first real job came the last year at school, when he fixed registers and worked on computers at a big box store. It was his favorite job yet, but it still didn’t pay well.

What Peter realized with all of these jobs was that he needed a better paying job! The only way to get that was to get trained or educated. He could go to school and get a 2­year degree in an office or technical position. His other choices were going to a 4­year college or joining the army. He wasn’t sure what he was going to do yet, but he knew he had to do something. Jobs were a lot of work, money was hard to earn，but he liked staying busy and being able to buy things. Peter wanted the most out of life, and that meant education.

Lately it has become fashionable in America to question whether it is really worth it to go to college. According to a new survey released by the Pew Research Center, only 40 percent of Americans felt that colleges provided a good value for the cost. At the same time,86 percent of college graduates still felt the investment was a good one for them.

There are a number of reasons for the widespread dissatisfaction with college. First, there are plenty of problems with higher education—poor quality and out-of-control costs are two of the biggest，Second， it is true that college is not for everyone.There are plenty of rewarding and important careers that do not require college.And due to the slow economy，there may in fact be more graduates than the current job market needs.Besides，anti-college sentiment is nothing new· Today，Microsoft’s Bill Gates or Apple’s Steve Jobs—both college dropouts-is often held up as evidence of why all that time sitting in class is better spent elsewhere.

However，getting a college education is still a good idea.College graduates earn more，and are more likely to have a job in the first place.According to the statistics last year，the average weekly earnings for someone with some college but no degree were$712，compared to$1，038 for a college graduate.That is almost$17，000 over the course of a year and there is an even bigger divide for those with less education.Meanwhile，the unemployment rate was 9.2 percent for those with only some college and more than 10 percent for those with just a middle school degree，but it was 5.4 percent for college graduates.The economic gaps between college completers and those with less education are getting larger·

Although most Americans surveyed by Pew feel doubtful about the value of a college degree，an overwhelming majority of parents Pew surveyed still expect their children to go to college."It call be inferred that the increased doubt has not significantly influenced decision making." Pew's Taylor says.“Despite the concern about rising costs and other problems，college remains a universal desire in this country.”

In ten minutes I had seen all that could be seen in the fish, and started to look for the professor—who had, however, left. Half an hour 6l—an hour—another hour; the fish began to look disgusting. I turned it 62 and around; looked it in the face—ghastly; from behind, beneath, above, sideways—just 63 ghastly. I 64 not use a magnifying glass, 65 instruments of any kind. Just my two hands, my two eyes, and the fish: it seemed a most limited 66 of study. With a feeling of desperation again I looked at that fish. I pushed my finger down its throat to feel how 67 the teeth were. I began to count the 68 in the different rows, until I was convinced that was nonsense. At last a happy thought struck me—I would 69 the fish; and now with surprise I began to 70 new features in the creature.
