Question

astronaut n.宇航员 (1) 宇航员可以派出机器人在这颗陌生的行星上工作，收集岩石和矿物; 建立永久性观察站，或向四面八方走动。(2) 我儿子的理想是当宇航员。(3) 载有受过训练的宇航员的火箭马上就要发射了。(4) 这火箭能把宇航员送入太空。(5) 在他三十岁的时候他将成为一名宇航员。 The word astronaut includes the root naut, from nautes, the Greek word for "sailor." This suffix can be used to create many travel-specific words. For example, the Argonauts were mythical Greek sailors on the ship named the Argo. Astronaut gets the astro from the Greek word astron, meaning "star," making an astronaut a “star sailor.” Russian space explorers took the title cosmonauts, with the cosmo part coming from the Greek for "universe," kosmos, so both have the same meaning.
