A Letter to All the Parents

Dear parents,

Swimming safely has become a very serious problem these years. Now the weather is getting warmer and warmer, please keep a close eye on your children. Tell them to be_  1.    when playing in the water. At school teachers try their best to let kids know   2.    to take care of themselves. But we still hope parents play the most important part. So make sure your children know the following things:

l. The most important thing is that you    3.  swim in a deep river.

2. Don't go swimming by    4.   . If you want to swim, you have to go with teachers or parents.

3. Not every place is proper for swimming and never try swimming if you are ill.

4. Before you swim, you should get ready for it    5.    of jumping into the water in a hurry(匆忙),

5. Ask for help when someone is in   6.    . Never try to help others  7.  you are not really good at swimming.

Swimming is a good way to have fun and exercise. But children are not old enough to take good care of themselves. That    8.    we should work together to make them safe.

Hope all the children in our country safe, healthy and happy.
