这是说,一个巨大的小行星撞地球小行星撞击65000000年前,这当然给地球的生态系统生态系统变成一场灾难,经过几千年的时间来恢复.科学家们说,这是可能的,这样的灾难会再次发生.
Asteroids
are rocky bodies which tend to live in orbits轨道between Mars and Jupiter.Comets,
on the other hand,are a mix of rock and ice,and they can swing into the
earth’s orbit from anywhere in the Solar System.Comets have an icy tail which
reflects the sun and can therefore be seen from the earth.But asteroids have
far less visibility可见度and have to be at least half a kilometre across to be
found.There are millions of such rocky and icy bodies out there which have not
been discovered yet.
小行星的岩石体往往生活在火星和木星轨道之间的轨道.彗星,在另一方面,是一个混合的冰和岩石,他们可以进入地球轨道与太阳系中的任何地方.彗星的彗尾的反映太阳,因此可以从地球上看到的.但是小行星有更少的能见度可见度必须至少50千米被发现.有这样的岩石和冰体存在,尚未发现数以百万计.
But did
an asteroid kill the dinosaurs — and could another kill us?
但没有一颗小行星杀死了恐龙,另一个杀了我们?
Despite
what you may have heard,it hasn’t been proved that the hitting was the only
reason for the dinosaurs’ dying out.But the asteroid which created the hitting
would certainly have had a great effect on the environment,and a mass
extinction灭绝did take place around the time.
你可能已经听说过,它没有被证明,打击的是恐龙灭绝的唯一原因.但造成打击肯定有小行星对环境有着巨大的影响,和大规模灭绝灭绝确实发生的时候.
So far we
have no idea when the next one will be because we haven’t spotted it yet and not
many organizations are spending money on asteroid-detection行星探测,because a
deathly hitting is such a faraway possibility.
到目前为止我们不知道下一个会因为我们没有发现它而不是许多组织都把钱花在小行星探测行星探测,因为死亡打击的是这样一个遥远的可能性.（你就不给加点悬赏吗.
