The 小题5: speed of light produces some strange facts. The 小题6: star is so far away that light which you can see from it tonight started to travel to you four years 小题7:________ at a speed of nearly two million kilometers every minute. The light from some of tonight's started on小题8: ________ journey towards you even before you were born.
So, if we want to be honest(诚实), we can not say , " The stars are shining 小题9: ________tonight." We have to say, " The stars look nice. They were 小题10:_______ four years ago but their light has just reached our earth. "

试题分析::这篇短文主要针对光比声音的传播速度快100万倍这个话题进行了初步讨论,并通过举例帮我们生动形象地理解这种差异,最后提出了一些由此推论出来的奇怪结论。
小题1:在一秒之内,光的速度是30万千米。在一秒之内,通常用介词in,表达时间;故答案为in。
小题2:根据第一句Light travels at a speed(速度) which is about a million times faster than that of sound .光的传播速度是声音的100万倍,故此处说声音的速度是340米符合文意;故答案为metres。
小题3:通过观看赛跑运动开始的过程可以对这种差异有一个大概的概念,因为后面提到通过观看发令员强中冒出的烟来判断比赛的正式开始,故答案为watching。
小题4:这句是用来解释光比声音传播速度快的,所以,在距离发令员较远的情况下可以通过观看发令员枪中冒出的烟雾来判断比赛的开始,故答案为come。
小题5:产生一些奇怪现象的原因正在于上文描述的光的极速,故答案为fast。
小题6:根据后面that引导的结果状语从句中的内容可知,此处描述的是距离我们最近的行星的状况,故答案为nearest。
小题7:今天晚上你能看到的光线在四年前就以极快的速度开始运行了,强调的这种奇怪的现象,故答案为ago。
小题8:本句进一步描述奇怪的现象:今晚你所看到的一些光线可能在你出生之前就开始了它的行程了。Start on one’s journey,此处的its指代the light’s (journey),故答案为its。
小题9:如果要诚实面对事实,那就不能说:“今晚的光线很耀眼”,brightly是副词修饰动词照耀shine,故答案为brightly。
小题10:他们四年前就在照耀着大地,只是现在他们的光线才刚刚到达我们的地球这里。根据文意应该是照耀,用过去进行时,故答案为shining。
