http://www.newdu.com 2020-05-09 网络 佚名 参加讨论

    英语阅读理解在中考英语试题中所占比重较大,同学们在平时的中考复习要多做练习题进行巩固。中考网整理了《2017中考英语阅读理解训练:The Speed of Light》,供大家参考。
    The Speed of Light
    Light travels at a speed which is about a million times faster than the speed of sound.
    In one second, light travels about 300,000 kilometres.
    But sound travels only 0.344 kilometres .You can get some idea of this difference by watching the start of a race. If you Stand some distance(距离) away from the starter, you can see smoke come from his gun
    (枪) before the sound reaches your ears.
    This great speed of light produces some strange facts. Sunlight takes about 8 minutes to
    reach us. If you look at the light of the moon tonight, remember that the light left the moon
    1.3 second before they reached you. The nearest star is far away from the earth. The light
    which you can see from it tonight started to travel towards you four years ago at a speed of
    nearly 2 million kilometers one minute. In some cases(情况) the light from one of
    tonight‟s starts started on its journey to you before you were born.
    If we want to be honest(诚实), we can not say “The stars are shining tonight.” We have
    to say, “The stars look pretty(漂亮). They were shining four years ago. But their light
    has only just reached the earth.. ”
    判断正误:
    ( )1.Light speed is about a million times faster than sound speed.
    ( )2.If you stand 100 metres away from a starter, you can hear the gun before you see
    the smoke.
    ( )3. The moon must be about two million kilometers away from the earth.
    ( )4. The sun must be about 480 times300,000 kilometres away from the earth..
    ( )5. The moonlight we see tonight started to travel towards us four years ago.
