A new kind of operation has become possible. Doctors take out part of the human body and replace it with artificial parts. Teeth are replaced with silver or gold, and blood vessels are replaced with plastic tubing. These artificial parts work almost as well as the real ones. People live longer and more comfortable lives thanks to this medical advance.
一种新的外科手术变成可能。医生把人体的一部分摘除，用人造器官替换。牙齿用银或金替换，血管用塑料管替换。这些人工器官几乎和真的器官一样工作。全靠这些医学的进步，人们才得以活的更长寿更舒适。
