Find the sentences with themodal verbs and write them down into your exercise book. Underline the modal verbs and explain how they change the meaning of the main verb.

People are always asked what they want to be when they leave school. I think it’s
a pretty tricky question to answer, especially when getting a job seems such a long
way off.
Magazines for teenagers often offer questionnaires and surveys to help young
people see their interests and abilities more clearly and make a decision concerning
their future career. Special tests can find out what a person is best suited for.
Those who like to work with machines can get a profession as a mechanic, a driver,
a pilot, a computer programmer etc. Those who like to work with people can be doctors,
teachers, lawyers, shop assistants, hairdressers etc.
When you are choosing a profession, you should keep in mind all the ne cessary
qualities, which are required for it. If you don’t possess them, you have to try to develop them in yourself.
People, who are active, energetic, “green”, tidy, practical and organized can choose
a profession of a vet, a postal worker, a dog trainer, or a zookeeper.
If you like adventures, trips, learning culture and traditions of other people you can
be an archaeologist, an explorer, or a tourist guide.
If you are interested in science and research you might be a scientist or an inventor. Those who are fond of working with numbers can get success in the career of an
accountant or a banker.
If you want to become a teacher, a nurse, a dentist, a doctor or a firefighter, you
must be helpful, caring, calm, patient, friendly, cheerful and outgoing.
If you are logical, critical, ambitious, and quick-minded, you might be a computer
specialist, a politician, a businessman, or an advertising designer.
The world of professions is rich and exciting. Some jobs are traditionally considered to be “women’s jobs” and some “men’s”. There are some jobs where both men
and women work successfully. What is really true is that all professions are important,
wonderful and necessary.
A high qualification makes a person fit for a certain position. “Every man
is the maker of his own fortune,” Richard Steele wrote. The person who wants to
be highly qualified must have good education first of all. A young person can best
approach the future when enriched with knowledge of many different subjects. That
can really help to get a better job, develop a career and get success in life.
