一、阅读理解
We know that it is hard to drink in space because of the low gravity, but Chinese astronauts Jing Haipeng and Chen Dong showed us how they drank tea on a TV show during the month-long trip in Shenzhou XI spaceship in 2016. They used a specially-made tea cup and a special Pu'er cream to drink tea while standing upside down.
"Drinking hot tea is harder," said Jing Haipeng. "The difficult part of drinking tea in space is that there should not be anything left after the tea dissolves (溶解) in water. Also, the solubility (溶解度) of the tea should be low since water in space can only be heated to 60 degrees at most."
The tea cream the astronauts drank was produced by a tea industry corporation in Kunming. Zhang Guanghui, manager of the corporation, said that the company tried to produce a tea cream that was safe and healthy. Some tea products are reported to be polluted by air and heavy metals. "I never imagined that one day our tea cream would help astronauts to drink tea in space," Zhang said. "For us, astronauts' drinking tea in space means our technology used in the tea industry has had some achievements," Zhang said. "In the future, more tea producers will use
it to improve the tea industry."
