Составьте 10 вопросов по данному тексту:
You are a Student Now
College life is a thing which you can hardly forget. This is the time when you become an adult, a more sensible person with the sober views on life.
First of all, to pass entrance exams and enter the university is a real challenge for a young person. It takes a lot of time, knowledge, patience and nerves. Besides, there is an avalanche of work expects you. A student ought to get accustomed to a new timetable, new subjects which are much more complicated than at school. Very often it is difficult to cope with the work load of college or university. You have to be a serious, attentive and responsible person concentrated on studying. Some new students soon understand that studying at university is hard work which takes a lot of time and strength, so they immediately start missing classes. This is not so good for them, because it is so difficult to catch up with the programme later. Besides, such students usually have a great number of debts before the beginning of examination session.
Another point is the relationships within a group and between students and teachers. It is not a secret that relationships play an important role in student’s life. You spend a lot of time at the university communicating with your group mates and trying to make a contact with other students. It is wonderful if you find a like-minded person who can become a real friend for all 5 or 6 years of studying or you just meet interesting people who are easy in communication. Sometimes an opposite thing may happen. When you see your group mates for the first time, it may seem to youthat they have nothing in common with you. Then the atmosphere within the group is just unbearable. Things get worse and it becomes difficult to find even a topic for conversation. Different things happen during your college life. Anyway, it is extremely important to have good relationships with your group mates and teachers and to show the best qualities and features of character.
In conclusion, it should be mentioned that students come across a lot of events during their studying in college or university. Some of them may disappoint you, some bring a lot of joy and even make you feel happy. That is why a lot of people say that their college or university years were the greatest and the happiest time in their life. They also say, that if they could go back in time, they would have taken a music band and joined choir, learned harder another language besides the English language, and improve the relationships between teachers who they have no special liking. They got in love for the first time in university, they went to party, got lots of joy and positive emotions, got in different competitions, and etc., but anyway, they think that the college life is the happiest time in their life.
I am a student too, and I think that my university life I can hardly forget. For me, it is time when I become an adult, a more sensible person with the sober views on life. Also I think that never forget to study and you can be a student for all the time.
