I know many of you like outdoor activities. So, do you like climbing mountains? Raise your hands if you do. （等待学生举手） S: （部分学生举手） T: Great! It seems quite a few of you are fond of mountain climbing. Now, think about all the mountains you've climbed. Among them, which one is the highest? Can anyone share with us? S1: I climbed Mount Tai. It's about 1,545 meters high. T: That's wonderful. Mount Tai is a very famous mountain in China. But in the world, of all the mountains, which is the highest? S: Qomolangma! T: Exactly! Qomolangma is higher than any other mountain in the world. Do you know how high it is? S: 8844.43 meters! T: Right! You are so smart. Now, what else do you know about Qomolangma? Who can tell me something more? S2: It's part of the Himalayas. T: Excellent! And where is it located in China? S3: In the southwestern part of China. T: Perfect! You've done a great job. Now, look at the picture on the screen.（展示珠穆朗玛峰的图片） This is Qomolangma. It looks so magnificent and mysterious. But do you think climbing Qomolangma is an easy task? S: No! T: Why do you think it's not easy? What dangers do you think can happen when people climb Qomolangma? Discuss in pairs and then share your ideas. S4: Thick clouds cover the top and snow can fall very hard. T: Good point. The weather on the mountain is really unpredictable. What else? S5: It is very cold and there are heavy storms. T: Absolutely. The freezing weather conditions and heavy storms can make the climbing extremely difficult. And another problem is that as you get near the top, it's very hard to take in air. Because the air there is very thin. Now, let's move on to our new lesson. Today, we are going to read an article about Qomolangma. The title of the article is "Qomolangma — the Most Dangerous Mountain in the World?" Look at the title and the picture again. What do you think the passage will mainly talk about? S6: Maybe it will introduce Qomolangma and the reason why it's dangerous. T: Very likely. Now, let's open our books to page 50 and start reading. 二、词汇讲解（New words learning） T: Before we read the article, let's learn some new words and phrases. First, look at the word "achievement". It means the things you have successfully done, especially after a lot of effort. For example, we felt a great sense of achievement when we won the basketball game. Repeat after me, "achievement". S: Achievement. T: Good. Next, "southwestern". It is an adjective which means in or from the southwest part of a place. For example, Sichuan is in the southwestern part of China. Read it together, "southwestern". S: Southwestern. T: Then, "thick". It describes something that is not thin. For example, the book has a thick cover. Or, as we mentioned just now, thick clouds cover the top of Qomolangma. Read it, "thick". S: Thick. T: "Include" means to have something as part of a whole. Her hobbies include dancing and singing. Repeat, "include". S: Include. T: "Freezing" is used to describe very cold weather. It's freezing outside today. Let's read it, "freezing". S: Freezing. T: "Condition" refers to the situation something or someone is in. The condition of the old house is very poor. Say it aloud, "condition". S: Condition. T: "Take in" here means to breathe in.

S: Succeed. T: "Challenge" can be both a verb and a noun. As a verb, it means to test someone's ability by making them do something difficult. As a noun, it means a difficult task. For example, The job challenges me a lot. It's a big challenge for me. Read it, "challenge". S: Challenge. T: "In the face of" means when you are dealing with a difficult situation. In the face of difficulties, we should be brave. Read it, "in the face of". S: In the face of. T: "Achieve" means to succeed in doing something, especially after a lot of effort.

Then match each paragraph with the main ideas on the right side of the page. Paragraph 1, spirit of climbers; Paragraph 2, achievements of climbers; Paragraph 3, facts and dangers. Start! （学生快速阅读文章，完成匹配任务） T: Okay, time's up. Let's check the answers. Who can tell me which main idea matches Paragraph 1? S7: Paragraph 1 matches facts and dangers. T: Right! Paragraph 1 mainly tells us some facts about Qomolangma, like its height, location, and the dangers of climbing it. How about Paragraph 2? S8: Paragraph 2 matches achievements of climbers.

S: They run along the southwestern part of China. T: Exactly. And how high is Qomolangma? S: It is 8,844.43 meters high. T: Right. Now, let's list the dangers of climbing Qomolangma. What are they?

And another reason is that the spirit of these climbers shows us that we should never give up trying to achieve our dreams. It also shows that humans can sometimes be stronger than the forces of nature. 四、知识点讲解（Key points explanation） One of the + 形容词最高级 + 名词复数 T: Now, let's look at some important language points in the article.
