Kids especially love the sorts of books which allow them to make a decision between various paths and choose their own endings.Set an exampleIf your child never sees you reading，they aren’t going to pick up a book either. 4Having plenty of books around the house makes reading more accessible and the normal thing to do when bored.

Buy them a special notebook. Allow them to write whatever captures their imagination，and don’t worry too much about messy handwriting or poor spelling. 5A.So how do you keep your kids interested in books?B.As long as a child is reading，it doesn’t matter what they are reading.C.Libraries will have a great range of books for children.D.There are newspapers printed especially for children.E.Reading and writing are often thought of as two separate issues.F.The idea is to cause an interest in books，reading and fiction，and the rest will develop over time.G.Next time pick up a newspaper or a book and encourage your child to sit with you and read too.二、完型填空My sister and I grew up in a little village in England.
