Part 3: Paras 7-8
Q1: What challenge did the capsule face when entering the atmosphere?
A1: There is fierce friction with the air. The surface temperature of the capsule can reach thousands of degrees.
Q2: What did researchers do to solve the problem?
A2: Researchers designed a heat-resistant coating on the surface of the Shenzhou XIII return capsule. They also laid a layer of ablative material.

Part 4: Paras 9-10

A1: Twice. Shenzhou VI and Shenzhou XIII.
Q2: What’s the advantage of landing upright?

Q3: What must the astronauts do to achieve an upright landing?
A3: Astronauts must operate and let go of parachute with precise timing.

V. Language study.
A. Can you find these expressions in the text?
1. 降落，着陆                touch down
2. 标志着一项重大突破        mark a major breakthrough
3. 创下新的速度记录        set a new speed record

② that引导的定语从句修饰ablative material；
③ when引导时间状语从句；
④ 划线部分为动词-ing作结果状语。
