这句英文里面包括的语法,还有为什么and后面要加个逗号?
Imagination grows by exercise and ,contrary to common belief ,is more powerful in the mature than in the young.
contrary to common belief -----这是插入语,可以省略,这样以来,Imagination grows by exercise 与 is more powerful in the mature than in the young就成了 一个主语 + 两个谓语:
imagination grows - - -AND is - - - - -.明白了吗?
再问: 既然是插入语, 可以省略的, 那为什么还要加入这句话呢?能给我举个同样的例子吗。 谢谢

再答: 插入语的存在指起强调作用,但不能左右句子的意思: it was raining heavily and , what was worse, her car broke down on the way.
