五、閱讀理解

56．In many stories on TV and in science fiction，humans can travel to stars far away．But so far，people have only been able to get to the moon．
What if a person wants to get to a star far away？it would take a lifetime to travel．People should have to move at least at the speed（速度）of light．But in fact，nothing can move faster than light．
Light travels more than 186，000 miles a second（秒），or about 11 million miles a minute．In one year，light travels about 6 trillion（6，000，000，000，000）miles．That great distance is called a light-year（光年）．It is used to measure（測量）distance in space．
Strange things happen to an object（物體）when it moves very fast．If an object moves at 86% of the speed of light，It will be twice as heavy as it is at rest．A stick appears shorter．A clock runs more slowly．A person would not age so fast in space as on the earth．
Alpha Centauri is the closest star to the sun．It is over four light-years away．So if a human traveled at the speed of light，it would take him nine years to go to Alpha Centauri and come back．
根據(jù)短文內(nèi)容，選擇最佳答案．
