T: Hello, class! We have already known a lot about the world's amazing natural wonders, like the highest mountain Qomolangma and the deepest salt lake the Caspian Sea. Today, we are going to dig deeper into the topic related to Qomolangma. But before that, let's have a quick review. Who can tell me some facts about Qomolangma that we learned last time? Raise your hands.

S1: Qomolangma is higher than any other mountain in the world, and it is about 8,848.86 meters high.

T: Very good! You remembered it clearly. Now, let's think about this. What difficulties do you think climbers might face when they try to climb Qomolangma? Discuss with your partners for one minute and then share your ideas.

(Students discuss)

T: Time's up. Who wants to share?

S2: Maybe they will face the cold weather. It is very cold on the mountain.

T: Right! The low temperature is really a big challenge. What else?

S3: There might be strong winds, which can make it hard for them to walk.

T: Excellent point! Strong winds are quite dangerous. Any other ideas?

S4: The thin air can cause breathing problems.

T: Exactly! The thin air at high altitudes is a major difficulty for climbers. Now, let's see what more we can learn about climbing Qomolangma in our new lesson.

Ss: challenge; Climbing Qomolangma is a great challenge for anyone.

T: Next, “in the face of”. It means when you are dealing with a difficult or dangerous situation. “In the face of difficulties, the climbers never gave up.” Read.

Ss: in the face of; In the face of difficulties, the climbers never gave up.

T: Then, “achieve”. It means to succeed in doing something, especially after a lot of effort. “They finally achieved their goal of reaching the summit.” Read.

Ss: achieve; They finally achieved their goal of reaching the summit.

T: “force”. Here, it means physical strength or power. “The strong wind is a powerful force on the mountain.” Read.

Ss: force; The strong wind is a powerful force on the mountain.

T: “nature”. We know it means the natural world, including plants, animals, mountains, rivers, etc. “The beauty of nature on Qomolangma attracts many climbers.” Read.

Ss: nature; The beauty of nature on Qomolangma attracts many climbers.

T: Now, let's practice using these new words and phrases. I will give you some situations, and you try to make sentences with the words we just learned. For example, I say “The students are trying to solve a very difficult math problem.” You can say “The students are facing a challenge in the face of this difficult math problem, but they will try their best to achieve the goal of solving it.” Got it? Now, I start. “The runners
