China's Grand Canal, which is 1800 kilomenters long, was built in 610 AD and flows through 17 cites, is oldest and longest man-made waterway in the world.这句话有没有语法错误？如果没有，为什么中间which从句可以有三个动词啊？动词也可以a,b and c的结构？which is, was and flow through?
China's Grand Canal, which is 1800 kilometers long, was built in 610 AD and flows through 17 cities, is oldest and longest man-made waterway in the world.除了 "oldest" 前面缺少 the 之外，这句话单纯从说语法上是对的，但是从句中的时间关系太乱：现在时 - 过去时 -- 再回到现在时，让人读起来非常不舒服。应简化句子结构、并理顺关系，比如China's Grand Canal was built in 610 AD and flows through 17 cites. At 1800 kilometers, it is oldest and longest man-made waterway in the world.如果实在希望把这些东西都放到一个句子里，可以说Built in 610 AD and running through 17 cities, China's 1800-kilometer(-long) Grand Canal is the oldest and longest man-made waterway in the world.
除了 指出的缺少一个定冠词以外，这句话在语法上确实没有问题。但是，这句话的结构比较奇特，属于。读者在阅读的时候，会自然而然地以为定语从句到第二个逗号为止，直到看到第三个逗号以后的部分，才发现句子似乎不通顺，必须回过头来看甚至努力思考一会儿才能明白句子的真正结构。由于这句话的结构会给读者造成阅读上的困难，所以我建议调整句子结构以方便阅读。根据你想表达的主要内容，可以调整四个动词短语的顺序，甚至把原句拆成多个句子。
唯一的问题：根据本句的内容，形容词最高级前面还是加个定冠词的好。谢邀。常见语法错误一_百度文库
