教材分析 This unit takes "computer" as the topic. In the Speak up part, students learn about the use of computers by students in the class in the form of questionnaires through group cooperation, and further discover the role of computers in daily life.

Ask students to stress the underlined part, use special stress to emphasize the words that want to be highlighted in the sentence, and then practice in pairs under the stressed words. In the Speak up section, we will make a survey in groups about other students' use of computers at home. Students will further understand the use of computers in daily life by reporting the survey results orally. Writing section, writing by email. Students use the comparative degree of adjectives to compare the two monitors in terms of size, weight, size and sales volume, and write a product recommendation email.
