关于based on 与be based on的区别和2个例句
numerous facts prove that marriage based on true love lasts and cannot be easily split up whereas marriage without love does not endure and may end in divorce.不是be based on 为什么不加be呢
the marriage based on true love often brings happiness.为什么这个也不加be 呢

优质解答

based on true love 在这里作marriage的后置定语,也就是过去分词做后置定语,不可能出现be,否则就有两个谓语了.
下一句是一样的
