T shows pictures of a penguin and a giraffe. Ss tell their knowledge about two animals. (Ex. 1) For Example：Penguins have short legs. They walk very slowly.Step 3. Pre-reading1. Play the recording of the dialogue and ask the students to read aloud with the speaker. 2. Ss look at the table, and guess which animal the children may choose. 3. Ss can write down their own guesses in the table.Step 4. Pre-readingT asks Ss to try to guess the answers to the following questions:Are penguins bird or fish?Penguins swim 15 / 25 / 35 miles an hour.Do giraffes spread their front legs to drink water?Can giraffes run for a long time? T helps Ss learn the word “spread”.Step 5. Reading.1. Ss read the text quickly and find the answers for the four questions. T calls back the answers from the class. T discusses with Ss about their understanding of the difficult sentence:They have to spread their front legs wide and bend their necks, so their heads can reach the ground.2. Ss read the text carefully, and find the information about the body parts of the two animals to complete the table. (Ex. 2) T checks answers in class. Ss describe penguins and giraffes with the help of the table in pairs.3. Ss discuss the structure of the text. T helps Ss understand that the texts are in two parts: appearance and interesting features. Ss read the second part of penguins carefully. T works with the Ss to summarise the features of penguins.
