  When July comes, children know they'll have     1   examinations and the
school year will end soon. Boys and girls will have a nearly two months'
holiday, and they'll leave school    2     train or by car to     3   to see their fathers
and mothers .
  The summer holidays are the    4     time of the year for most children. The
weather is usually good, so one can    5     most of his time playing outside. If one
lives in the country, he can    6     into the woods and in the fields. If one lives in
a big town, he can usually go to a park to play.
  The best place for a summer holiday is the    7    . Some children are    8   
enough to live near the sea. But for the others who do not, if they have the chance
to stay at one of the big seaside towns for a week or two, they will talk about it
all the following school year.
  Now,    9     makes children like the seaside so much? I think it is the sand,
the sea and the sun, not anything else. Of course, there are   10     new things to
see, nice things to eat, and interesting things to do. But the feeling of sand under
their feet, of salt water on their skin, and the feeling of the warm sun on their
backs make them happier.
