Light travels at a speed(速度) which is about a million times faster than that of sound .小題1:
    One second, light travels about 300000 kilometers, but sound travels only 340 小題2:     .  You can get some idea of this difference by 小題3:________ the start of a running match. If you stand far away from the starter(發(fā)令員), you can see smoke小題4:________ from his gun before the sound reaches your ears.
The 小題5:     speed of light produces some strange facts. The 小題6:    star is so far away that light which you can see from it tonight started to travel to you  four years 小題7:________ at a speed of nearly two million kilometers every minute. The light from some of tonight's started on小題8: ________ journey towards you even before you were born.
So, if we want to be honest(誠實), we can not say , " The stars are shining 小題9: ________tonight."  We have to say, " The stars look nice. They were 小題10:_______ four years ago but their light has just reached our earth. "

小題1:in
小題2:metres
小題3:watching
小題4:come
小題5:fast
小題6:nearest
小題7:ago
小題8:its
小題9:brightly
小題10:shining

試題分析：：這篇短文主要針對光比聲音的傳播速度快100萬倍這個話題進行了初步討論，并通過舉例幫我們生動形象地理解這種差異，最后提出了一些由此推論出來的奇怪結(jié)論。
小題1:在一秒之內(nèi)，光的速度是30萬千米。在一秒之內(nèi)，通常用介詞in，表達時間；故答案為in。
小題2:根據(jù)第一句Light travels at a speed(速度) which is about a million times faster than that of sound .光的傳播速度是聲音的100萬倍，故此處說聲音的速度是340米符合文意；故答案為metres。
小題3:通過觀看賽跑運動開始的過程可以對這種差異有一個大概的概念，因為后面提到通過觀看發(fā)令員強中冒出的煙來判斷比賽的正式開始，故答案為watching。
小題4:這句是用來解釋光比聲音傳播速度快的，所以，在距離發(fā)令員較遠的情況下可以通過觀看發(fā)令員槍中冒出的煙霧來判斷比賽的開始，故答案為come。
小題5:產(chǎn)生一些奇怪現(xiàn)象的原因正在于上文描述的光的極速，故答案為fast。
小題6:根據(jù)后面that引導(dǎo)的結(jié)果狀語從句中的內(nèi)容可知，此處描述的是距離我們最近的行星的狀況，故答案為nearest。
小題7:今天晚上你能看到的光線在四年前就以極快的速度開始運行了，強調(diào)的這種奇怪的現(xiàn)象，故答案為ago。
小題8:本句進一步描述奇怪的現(xiàn)象：今晚你所看到的一些光線可能在你出生之前就開始了它的行程了。Start on one’s journey，此處的its指代the light’s （journey），故答案為its。
小題9:如果要誠實面對事實，那就不能說：“今晚的光線很耀眼”，brightly是副詞修飾動詞照耀shine，故答案為brightly。
小題10:他們四年前就在照耀著大地，只是現(xiàn)在他們的光線才剛剛到達我們的地球這里。根據(jù)文意應(yīng)該是照耀，用過去進行時，故答案為shining。
