Wang Yuanzhuo, a research fellow at the Institute of Computing Technology of I the Chinese Academy of Sciences, even drew     4    (picture) to explain the science and technology theories     5    (present)in the movie to the young audience in simple language.

“I     6    (receive)many questions from my daughter and other kids concerning the movie in the past few weeks,” Wang Yuanzhuo,    7     is also one of the movie’s science consultants, wrote on Weibo.

According to him, the key to realizing space elevators is to find a super-strong material that can he used as the elevator cable. The material needs to have the ability to maintain good performance when it     8    (expose) to terrible conditions in space. But it might be long before space elevators could     9    (actual) become a reality.

Pursuing Space Truth

Compared to landing on the moon, landing on Mars is a most     1    (challenge) mission. China’s first fully homegrown Mars mission,Tianwen-1, is on its way to the Red Planet.

“Tianwen” got its name from a long poem     2    (write) by Qu Yuan, a famous poet of the Warring States Period, who raised a wealth of questions     3    (concern)the sky, natural phenomena, myths, etc.     4     the name’s deep roots in the Chinese traditional culture, “Tianwen” has been     5    (wide) accepted by the public, which also demonstrates the     6    (determine)of the Chinese people to pursue heavenly truth in deep space.
