宇宙飞船 - 中国宇宙飞船
宇宙飞船(英语名为 space craft,spaceship )，是一种运送航天员、货物到达太空并安全返回的一次性使用的航天器。它能基本保证航天员在太空短期生活并进行一定的工作。俄罗斯和美国在过去几十年来都已发射了多种型号的宇宙飞船，俄罗斯在前苏联时期发射了第一艘东方号飞船，后来又发射了上升号和联盟号飞船。美国发射了水星号、双子星座号、阿波罗号等载人飞船。
我国的宇宙飞船为神舟飞船系列，从神舟一号无人飞船开始到神舟十一号载人飞船，使中国成为继美、俄之后，世界上第三个掌握载人航天技术，和成功发射载人飞船的国家。
航天飞机和宇宙飞船有什么不同
航天飞机和宇宙飞船存在本质区别，宇宙飞船指的是位于火箭顶端，利用火箭推力进入轨道，返回时利用降落伞等降落在空旷地带或海上的载人航天器，而航天飞机是一种有翼、可重复使用的航天器。
宇宙飞船的特点是价格相对低廉，一般不可重复使用，是一次性的，在发射的时候，飞船会和火箭构成一个整体，在飞船的顶端还有逃逸塔，能在火箭出现问题的时候自动点火，牵引飞船迅速飞到安全区域，安全性比较高。
航天飞机在发射的时候是利用火箭推力从发射台垂直升空，着落的时候则是像普通飞机一样水平降落在机场跑道上，它一次升空可载七名宇航员和大量物质，但是缺点是由于重复使用会导致航天飞机机体老化，增加故障发生几率，且没有可靠的逃生手段，若是出现问题会造成重大灾难。

Staying by a Stump Waiting for More Hares To Come and Dash Themselves Against It This story took place more than 2,000 years ago,in the Warring States period（475-221 B.C.）.Tradition has it that in the State of Song at that time there was a man who was famous for staying by a stump waiting for more hares to come and dash themselves against it. He was a yong farmer,and his family had been farmers for generations.Year after year and generation after generation, farmers used to sow in spring and harvest in autumn,beginning to work at sunrise and retiring at sunset.In good harvest years,they could only have enough food to eat and enough clothing to wear.If there was a famine due to crop failure,they had to go hungry. This young farmer wanted to improve his life.But he was too lazy and too cowardly.Being lazy and cowardly over everything,he often dreamed of having unexpected blessings. A miracle took place at last. One day in late autumn,when he was ploughing in the field,two groups of people were hunting nearby.As shoutings were rising one after another,scared hares were running desperately.Suddenly,a blind hare dashed itself headlong against the stump of a dead tree in his field and died. That day,he ate his fill. From that day on,he no longer went in for farming again.From morning till night,he stayed by that miraculous stump,waiting for miracles to take place again. This story comes from"The Five Vermin"in The Works of Han Feizi.Later generations often use the set phrase"staying by a stump waiting for more hares to come and dash themselves against it"to show grusting to chance and windfalls or dreaming to reap without sowing.It is also used to show adhering to narrow experiences and not being able to be flexible
