Have students answer the two questions on page 2 before reading the documentary script. (1)What plants or animals do you know about? What is special about them? Sloths are one of the slowest creatures on the Earth. They live hanging upside down in rainforest trees. Modern sloths are smaller than the extinct giant sloths which were as big as elephants and lived on the ground. Giant redwoods are impressive because they can grow as tall as 83 metres and as wide as 21 metres. You can drive a car through their trunks. They have been around since dinosaurs roamed the Earth but are now in danger of becoming extinct. (2)What do you think this script is about judging from the title and pictures? I think the script “The Amazon rainforest: a natural treasure” is about the Amazon jungle and the plants and animals found there. They are all natural treasures because they are valuable to the Amazon. The pictures show that the plants and animals living in the Amazon rainforest are unusual and beautiful. There are different kinds of animals that depend on the rainforest for shelter 批　注 and food. 2. Have students read the documentary script and finish A1 on page 4.
