Doctors say that happiness is the secret of good health. This means we all have to look after ourselves. When we lose some things, we shouldn't get angry but just look for them trying to find them. If we don't understand some words people use, we should look them up in the encyclopaedias and we shouldn't get angry either. We should also remember that praise is good for us too. look at your friend and say how wonderful he is. Then he will believe he a good child. She will certainly be one. So remember, if we want to be happy and healthy, we need people around us who keep telling us how wonderful we are.

Summer holidays  Summer holidays are the longest holidays. I like them very much! 
      In June I went to the seaside with my parents. The water in the Black Sea was very warm. We swam and sunbathed. There were different kinds of entertainments there. Best of all I liked water scooters and discos. We also played volleyball on the beach and made sculptures of sand.   
     Then I spent two weeks in the summer camp. I made a lot of new friends. Every day we enjoyed something special - games, competitions, performances.
There was no river, but there was a swimming pool where we could swim. We had discos every night. It was a real fun.
   In August I visited my grandparents. There I enjoyed fresh air and helped my grandparents to dig the garden, to gather fruit and vegetables. I went fishing with my grandfather.
   During my summer holidays I made new friends, read a lot of interesting books, knew many useful things.
