I. Read the text and answer the questions: The New Year the So the old year has gone. There is still much talk about has winter holidays, but let's speak a little about the year which just begun. As you know, New Year's Day has been one of the main holi- days of the year for a very long time. New Year holiday celebra- tions are different in different places, but giving presents and send. ing greetings with good wishes are very popular in all countries. In the past people often tried to learn something about the fu ture by magic 1 during New Year celebrations. Well, we don't know what those people learned about their future and we don't know if their magic made it any better. But we certainly know one thing--the first school half-year wasn't easy for you and the second half-year is going to be still more difficult. And no magic will help an eighth-former if he doesn't prepare well for the exam. inations The New Year promises much work for you and there are only a few months in which you can do it. That's why it's very impor. tant to plan your time well now And there is another problem. Do you think you'll have enough time to decide what to do after finishing the eighth form? It's better, of course, to decide that difficult question before school is over for the year. So you see, the New Year will be both difficult and interesting, and it may bring a great change in your lives.
