Explain their meanings and pronunciations. For example, when teaching "global warming", say: "Global means all over the world, and warming means getting warmer. So global warming means the whole world is getting warmer."

Then, give some words containing these sounds, such as "train", "drive", "look", "run", "window", "about", "good", and ask students to read them aloud, paying attention to the correct pronunciation of the target sounds. Correct students' pronunciation errors in time. 5.4 Listening Activity 1 (7 minutes) Tell students: "Now, we are going to listen to a weather report.

Encourage students to collect more information about global warming and share it in the next class. 教学反思 In this class, students showed great interest in the topic of global warming. The use of pictures and real - life examples in the lead - in part effectively attracted students' attention and motivated them to participate in class activities. However, in the pronunciation practice part, some students still had difficulty in differentiating and pronouncing some sounds correctly. More individual guidance and practice should be provided in the future. During the speaking activity, most pairs could communicate smoothly, but some students' expressions were a bit limited. It is necessary to provide more useful sentence patterns and vocabulary for students to enrich their speaking content in the following classes. Overall, through this class, students have a better understanding of global warming, and their listening and speaking skills have been improved to a certain extent. But there is still room for improvement in teaching methods and content delivery to better meet the needs of different students. 2 / 37 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $
