[originaltext] Summer means internships for thousands of American college stu

Summer means internships for thousands of American college students. They work in the kinds of jobs they might want to have some day. Experts say at least one-third of all American college students complete an internship before they graduate. Most work at an internship during the summer when they do not attend classes. Some work at an internship during other times of the year. Others do an internship soon after completing college. Some students work for large companies. Some work for small organizations. Some work for the United States government.
   Many interns do not earn money at their summer jobs. Some college students get an internship to gain experience in the kind of job they want to get after graduation. Others do not yet know what kind of permanent job they want. So they may get internships in several different companies or organizations. In this way, they can find out what kind of job they like best. Why are internships so popular? Students can learn about different kinds of jobs. They can do interesting work. They can learn skills and gain valuable experience. And they can meet important people. Students often describe internships as a chance that happens once in a lifetime.
