80 Баллов!!!! Ребят, помогите составить 10 вопросов к тексту:
• Define and fix the time for your activities (lessons, homework, your way
to school and back, meals, sleep) and your rest.
• Make sure you have rest time every day.
• Try to break your timetable into periods not longer than half an hour.
It will help you to concentrate on your activity.
• At the end of each period write down the results of your learning or
revising activity (make notes, select some key words, etc).
• After each 30 minute period of work, give yourself a short rest. It will
provide some relaxation and good mood for a day ahead.
• As soon as you feel some success in coping with your time in this way,
make your serious activity periods longer.
• When you realise that this approach to your time management
is productive, look through your timetable again, define the
most challenging topic and break it into shorter parts.
• Analyse the results of your work during a day and think of
the place where you study better: at home (in your room, in
the kitchen, in your garden, etc) or out (at school library, at
your friends', etc).
• Think of your personal manner of learning things (reading
to yourself, reading aloud, making notes / keywords,
representing the information visually, repeating the
information aloud, listening to your friend who reads the
text, etc). Choose the manner which is most convenient for
you and learn things in this way when possible.
Tense student
One of your main problems is lack of self-confidence. That's why revision
is delayed and you have many self-doubts. The more negative thoughts
you have, the more anxious you feel. You tend to exaggerate your weaknesses
and expect everything to be bad. As a result you may confuse thinking with
feeling — if you feel stupid it doesn't mean you are.
The main aim is to make your self-talk constructive. Think what
you would tell your friend in a similar situation. Probably something
encouraging and realistic — so now you need to practice saying it to yourself! Here are you tips:
• Try to realise your fears and worries. Why do you believe that your future
completely depends on the results of your exams?
• Plan your work in advance. Break a large task into smaller parts.
• Start doing your task step by step. Base on your positive personal
experience of doing similar tasks.
• Be optimistic. Appreciate your own success and avoid comparisons with
the outcomes of your classmates. Remember that he / she might be more
successful in this specific activity, but there are things you do better.
• Every morning you wake up think positively about a big day ahead of you.
First of all plan a realistic study schedule. Say to yourself: "It might be a
busy day, but a successful and productive one. I'll do it!"
• Remember that in 10-12 hours the day will be over! And the challenging
task or threatening exam will be in the past soon.
Try to support your friends who are even more nervous — it will give you a sense of self-confidence.
Perfectionist student
Have you noticed that you can be a perfectionist? It happens rather
often, but sometimes you experience a real trouble with managing
your time. Your perfectionist expectations push you to do a lot of
unnecessary work. You often feel stressed out because of trying to do things
"perfectly". Here are the tips for you:
• Remember that you study for yourself, and you should be healthy to
realise your plans in future. Be less harsh on yourself!
• Try to make difference between the things you should and you must do.
It will give you a chance to avoid stressful situations and to make your
high expectations more realistic.
• Discuss your expectations with your parents and friends. They know you
well and their opinion might be useful for you.
• Don't be afraid to make some mistakes. All people make mistakes from
time to time. No use being too critical to yourself. Give yourself credit.
• Planning your day try to break your timetable into shorter periods: not
longer than half an hour for a certain activity. Then relax for some time.
• Watch how your classmates work. Being aware of various personal styles
of learning will make you more tolerant to yourself.
• Do remember that nothing is absolutely perfect! In any of your activities
you should see a possibility of doing things better. That will give you a
perspective for the future and contribute to your creative thinking.
