Today I’m going to talk about rainforests. Are you       with them? They’re interesting and exciting places! Many kinds of the world’s plants and animals live in the rainforests.
However, rainforests are    now---they are disappearing very fast because they are cut down or burnt every day. As a result,    animals and plants are dying out.
Maybe you have never been to a rainforest, so why should you protect them     ?  Rainforests are important to everyone. They are important because the plants in the rainforests make oxygen . We need oxygen to breathe.
