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7】ago
【小題8】its

解析試題分析::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(jìn)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(dá)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(yuǎn)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(jìn)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(dá)我們的地球這里。根據(jù)文意應(yīng)該是照耀,用過去進(jìn)行時,故答案為shining。
