voice 1: That sounds like a very fast computer! But the process took thirteen years to complete. That is two years less than the scientists predicted. Scientists called the complete set of DNA code a genome.
声音1：这听起来是一台非常快的计算机！但是这一过程历时13年才完成。这比科学家预计的时间快了两年。科学家将全套DNA密码称为基因组。

voice 2: When scientists finally finished mapping the human genome in April 2003, they found many surprising results! The human genome is made up of three thousand million different important pieces. Of these three thousand million pieces, only three million are different in every person. That means that ninety nine point nine percent of people's genes are exactly the same!
声音2：当科学家最终于2003年4月完成人类基因组的绘制时，他们发现了许多令人惊讶的结果！人类基因组由30亿个不同的重要部分组成。在这30亿中，只有300万在每个人体内存在不同。这意味着人们的基因有99.9%是完全相同的！
