Написать 5 разных вопросов к тексту
вот текс нужно 5 разных типов
After finishing school students have to decide if they want to continue their education, There is a great choice of vocational schools, colleges, institutes, universities and academies, that provide professional education and prepare for a future career. If school-leavers want to be independent from their parents and earn their own living, they can find a job that doesn’t require any special education or professional training.
I believe that it’s not easy to choose a job, we should take into consideration our abilities, personal qualities and interests, moreover, it is necessary to know the demand for a particular career in the labour market.
As for me, I am good at Maths and Chemistry. My friends think me to be easy-going, friendly, imaginative and creative, however, my teachers often complain that I am a bit lazy and absent-minded. I am interested in (learning) foreign languages. I believe knowledge of the English language will help me to make a career because English is the major language of communication in science and technology, trade and cultural relations, commerce and business, mass entertainment and international tourism. It is the universal language of international aviation, shipping and sports. It is also the main language of diplomacy, therefore, whatever sphere I will choose, knowledge of English will be extremely beneficial.
When choosing a profession we can turn to our parents and friends for advice. Our choice of a job can be influenced by pressure from our parents, I am lucky because my parents respect my opinion and ambitions. Besides, there are occupational consultants who can help us to find the most suitable sphere of work with an opportunity to make a career and earn enough money to live a decent life. They can advise students to work in the medical, welfare or educational fields, in management, finance or science. Some jobs are more attractive than others, for example, the job of a journalist is considered to be attractive because it is exciting and prestigious, it requires travelling a lot, meeting people and being punctual. I’d like to avoid monotonous, exhausting and messy jobs.
The first step in planning a career is self-assessment. Self-assessment means learning about our interests, values, goals, aptitudes and skills. There are education and guidance programmes preparing young people for the opportunities, responsibilities and challenges of adult life. It is necessary to make use of information sources to learn about job placement. We can look for jobs at different places, we can be employed by the government or a private company and have a secure full-time job with a prospect of promotion and financial reward. I don’t mind working long hours on condition that I am well-paid for it (=working long hours), if I need money I might take an odd job from time to time. I am not adventurous, that is why I wouldn’t like to be freelance.
I haven’t made up my mind yet what profession to choose, I am thinking about being a computer specialist but I might change
