     Was there anything new at your school at the beginning of this term? Students in England are getting
an extra two  1  to sleep in the morning.
     This year, schools in England decided that students should start class  2 . This should help them feel
less  3 . For Junior high schools, the first class will begin no earlier than 11:00 am.
     The changes have made students happy.
      David, 15, said his class was  4  by the news on the first day of school. "It's so good we can get up
later!" said he.
      David studies in North Tyne River School. He  5  get up at 7:40 am and go to school before 9:00 am.
But now he can get up at  9:40 am because class doesn't start  6  11:00 am.
      Marsh, 15, said the new schedule is good for her study. "I used to drink coffee every night or I would
feel  7  finish my homework," said Marsh. "Now I can finish it without coffee." She used to get up at 7:30
am. Now she can get up at 9:30 am.
      Linda's  8  was happy, too. She thought more sleep  9  make her daughter grow taller.
      But some parents worried  10  more sleep would mean less learning. There used to be  11  classes in
the morning. Now there are only two.
      Many teachers, though, say the changes will help students  12  better.
     "Students used to fall asleep for the first two classes  13 . It's really a waste of time because it's the
best time of day to study." said Thomas, a teacher in North Tyne River School. "But now  14  look fine and
learn much better than before."
      Do you sleep enough? If there are other ways in which you can get  15  sleep, welcome to write to us
and talk about your idea! Also you can e-mail us, Good life @hot.mail.
