请问这里为什么用leading,ing形式Conversely, growth factor restriction could result in the activation of these substrates, leading to subsequent initiation of autophagy.
A dog was running on the playground,following a boy. 一条狗在操场上,跟着一个男孩跑步.
A boy was running on the playground,followed by a little dog. 一个男孩在操场上跑步,后面跟着一条狗 再看看你的问题,growth factor restriction是主语,在这句话后面有个逗号,后接leading,则说明这个leading动作是growth factor retriction主动发出的。如果这个地方用lead,将表现不出这句话的主语是什么,那就矛盾了。
分词作状语。 你记住,一个句子(一个主句或从句)只能有一个谓语动词(表现时态、单复数)。其他的动词形式发生变化,可以表因果、让步、同时发生等等(不用仔细区分)。 如此处意为“……,这导致了(leading)……” 例: She rushed into the room, seeing the boy having a cigarrete.
