Task I. Read the text,
My Dream Job
I'm still at school but I think about my future profession all the time. I like several different areas of work but I'm the
most attracted by the tourism industry. The job of my dreams is the work on a foreign cruise ship
After I finish school I really want to try doing any kind of a job on a cruise ship whether it's an administrator, a
steward, a bartender, a waiter, a tourist entertainer or a guard etc. It's necessary so I can understand if I like working
on cruise ships or not and to get the experience I need. I would like to work for about a year and then I would study
tourism management
What do I like the most about this job? First of all, it will help me to travel and see different cities and countries and
to know the world better. Secondly, obviously it's the ability to communicate with people from all over the world. I
will have to learn several languages and it's a very useful skill to have in life and I will know a lot about other
nations. Thirdly, it's an opportunity to live and work in an international environment so you can make friends and
connections in every corner of the world. And the last thing, it's a good salary that will help me to live securely
