_______________________________________________________________________________________[答案]

   Last week, we did research into how laid-off workers get their new jobs. Some students surfed the Internet and learned that most of the laid-off workers had already got their new jobs.  The city government provided a vocational training center, where five courses for laid-off  workers were offered. After training, they began working as repair workers, cooks, typists, household workers and salespersons. The other students interviewed some laid-off workers who had got new jobs.  A woman said, "With The help of the government I've found my new job."

    What a great deal we've learned through the research !
