Exercise 4: Read the text and choose the correct answer. I am in the reading room with my friends: Mai Anh, Louis, Peter and Hoa. We are reading books about anomals. Look at the zebra. It has two colours: black and white. Mai Anh likes zebras because they are beautiful and fast. This is a crocodile. It's so scary and dangerous. It has sharp teeth. We don't like crocodile because they are scary. This is a lion. It's big and strong. It's fast, too. Louis likes lions very much. Peter and Hoa don't like lions. They like monkeys because they are very smart and cute. 1. - What are the children doing? - They are _____ books about animals.
