29、Tian Gong Space Station has been the pride of our country. What many people dont know is that the astronauts face many risks every day.

32、 hit an old Russian rocket in 2009, it broke into more than 2, 000 pieces, increasing the amount of space junk.To reduce additional space junk, countries have agreed that all new space tools can only stay in space for 25 years at most.

39、f pollution. Its the Citarum River.

47、o the planet can hardly support more people, can it? The answer to this question may be “Yes”. David Satterthwaite is an environmental scientist.

58、River as their main source of water. In 2021, the river was reported to be drying up. Because of climate change, theres also less snow in the mountains of Tibet.

59、 reasons for water shortages. For example, water pollution makes it harder to get clean drinking water. Factories and farms dont use water efficiently.
