问下后置定语
请问是The professor explains two ways plant using to protect themselves.
还是he professor explains two ways plant used to protect themeselves.
怎么区别呢,
问下后置定语请问是The professor explains two ways plant using to prot
当然是The professor explains two ways plant using to protect themselves.
因为use的主语是plant,植物用来保护自己的两种办法.这是主动的,非谓语动词要用ing.
过去分词表示的话,use的主语要变成ways ,方法是被用的,被植物用的,就会用used,表被动.
two ways used by plants
