They are free to come and go and nobody is allowed to kill any animal in Canada.They have a law against killing wild animals.If you killed an animal,you would be punished.If an animal happened to get run over by a car,people would be very sad about it.

  ①人类对浩瀚无垠的太空向往已久。从嫦娥奔月的神话到亦真亦幻的《西游记》,人们把太空描述成妙不可言的神仙世界。在人们的想象中,太空是一个至善至美的天堂。然而在现实世界里,太空绝不像人们想象的那样浪漫。进入太空,人类要面对的是险境而非仙境。载人航天飞行要解决的问题也远不只是“高处不胜寒”。

  ②载人飞行要克服的第一个难关是真空环境对人的影响。太空中没有空气,人体若裸露在真空中,将无法呼吸。如果宇航员的座舱、生活舱一旦泄漏气体,很可能导致宇航员死亡。

  ③需要克服的第二个难关是来自太空强辐射的影响,这种太空强辐射包括太阳电磁辐射和高能粒子辐射。太阳电磁辐射生的可见光和红外部分主要影响航天器的温度:会损伤航天器的一些表面材料,还影响高层大气的温度和密度,从而加重低轨飞行器轨道控制的负担。高能粒子辐射则直接对航天器本复产生影响。高能粒子长时间围绕地球运动,对低轨道航天器构成严重威胁。它们的辐射不仅损伤航天器表面材料,而且会使航天器内部的太阳能电池、有机材料、半导体器件和集成电路等的性能发生变化,甚至造成永久的损伤。

  ④空间碎片和流星体是载人飞行要克服的另一难关。空间碎片又被称为空间垃圾,是指废弃的火箭或卫星的残骸和它们因爆炸或碰撞而产生的碎片。它们与航天器的相对速度稍低于流星体与航天器的相对速度。它们始终和航天器一同在地球的周围运动,因此出现碰撞的机会很多。空间碎片和流星体与航天器相撞,会在航天器的表面留下撞击坑或穿孔,甚至造成航天器表面的机械损伤。体积相对较大的流星体和空间碎片,对人体和航天器的破坏都是致命的。

  ⑤另外,飞行过程中产生的噪声和振动也会对人体产生不良影响。火箭在上升过程中发动机会产生高强度的噪声,飞船高速穿过大气层时也会产生巨大的噪声。即使飞船在轨道运行时产生的相对小得多的噪声,也相当于繁忙交通路口的噪声,而且持续不断。而飞行产生的强度不等的振动会影响宇航员的心率、血压和耗氧量,可诱发心血管的功能紊乱。另外,人体或器械的振动也会使人视觉模糊,动作不协调,操作误差增加,语言明显失真或中断。

  ⑥可见,在浩渺的宇宙中,宇航员时刻面临着险境,而绝非想象中的仙境。(选自《飞向太空》,有删改)
