意思是:卫星数量小,但是体积大,相比起碎片来说。这体积大呢有个坏处,干扰了天文观察,因为它会反射。由于有些卫星没用了,但是体积还是那么大。为了减少这种干扰呢,准备炸了这些卫星,消除这种反射。 空格前说,这样的方法是有效的,后面只要支持就好了 E支持啊,小碎片增加了,减少了大卫星,减少了反射,有利于天文观察。 ------ A.many nonfunctioning satellites remain in orbit for years ----还是留着,不支持,去掉 B.for satellites that have ceased to function, repairing them while they are in orbit would be prohibitively expensive--花钱修理他们,无关。文中是要炸了他们 C.there are no known previous instances of satellites’ having been exploded on purpose---炸了卫星后果不好预测,那就是有可能好,也有可能反而更加严重的干扰了。有weaken的意味。 D.the only way to make telescope observations without any interference from debris in orbit is to use telescopes launched into extremely high orbits around the Earth------使用高轨道的绕着地球转的望远镜来观察,以减少碎片的影响。文章说是大卫星有影响。不要 |
