Or, job searchers can look in the newspaper. Local newspapers have employment announcements placed by companies seeking(寻找) workers.Another popular tool for finding jobs is the Internet. For example, people in four hundred and fifty cities around the world can use the Craigslist(网站名)Web site to buy objects, meet people or find a job. Craigslist says that it receives two million new job listings each month. Another useful way to find a job is through a college or university.

Of course, looking for a job requires knowing what kind of work you want to do. For example, there is a book called “What Color is Your Parachute (降落伞)?” by Richard Bolles.
