Children sometimes get sick(生病) and need to go to hospital. Some of them have to stay there for a few  (day). It is not good for them (think) about their sickness all day long. They need some other things to think about, so people ask animals  help. In some places, workers from zoos often (take) animals to visit children in hospital. They may bring a little dog or a  (cute) monkey with them. Children are  (exciting) to see them.

     ，some children cannot get close to the animals. The animals may make their sickness get even (bad). How can we help these children? The hospitals get another good idea. They work with zoos to make movies. The movies are all about lovely animals. Children in hospital can watch these movies and learn the animals'  (live) habits. A man(call) Denny Sanford made a TV network (网络)to show these movies. It is used in many hospitals in the US today.
