（In an English class)

Mr Wu: Boys and girls, yesterday I asked you to collect some information about China's Tianwen 1 probe. Let's see what you've    16   .

Li Ping: I downloaded something. May I use the PPT, Mr Wu?

Mr Wu: Sure.    17   

Li Ping: Look at this picture. On May 15, China's Tianwen 1 probe made a historic landing on Mars! Following the US, China is now the    18   country in the world to    19   land a probe on Mars. It will give Chinese    20   their first chance to study the Red Planet closely.

Gu Yue:    21   was Tianwen 1 probe sent?

Li Ping: In July 2020.The probe entered Mars orbit（轨道）in February 2021. Experts said the    22   of sending the probe into orbit was equal to hitting a small ball from Paris and landing it in a hole in Tokyo. And the final    23   was even more difficult.

He Mei: I hear it's    24   called the "nine minutes of terror".

Li Ping: Yes. In nine minutes, the probe had to reduce its    25   from 20,000 km per hour to zero, landing from 125 km above Mars.    26   the probe is 320 million km away from Earth, there is a signal delay（延迟）of over 10 minutes if the research team tries to control it from Earth. So the probe had to    27   the landing on its own!

Gu Yue: That's amazing!

Li Ping: Indeed. When the probe finally slowed down.at 100 meters above Mars.it stayed in the air and    28   the landing area. It had to move away from the objects in its way such as rocks,    29   finally touching down.

Mr Wu: Well done, Li Ping! Thank you for showing our    30   Tianwen 1 probe. Let's see who has something else to share…
