英语语法问题
这个句子中的 it is the intent should an accident occur 结构是怎么回事?看到it is本来期待它会是一个强调句,但后面的should把我搞懵了.请指教.
“It is the intent of these products to either prevent accidents from occurring in the first place or to reduce the injuries suffered by the wearer should an accident occur.”
原句来自gre范文

to reduce the injuries suffered by the wearer should an accident occur
这个应该是一个整体,should表示虚拟语气,你可以查一下should表示虚拟语气的用法.
表示一旦有事故发生,减少wearer所受的伤害
再问：可不可以这样解释“to either prevent accidents from occurring in the first place or to reduce the injuries”（作为it的真正主语） is the intent of these products， if an accident should occur（作为状语从句）。
再答：额差不多不过我觉得to either prevent accidents from occurring in the first place or to reduce the injuries suffered by the wearer should an accident occur 这个整个是一部分，是it代替的部分，这个产品的目的是整个部分，不是事故发生才有这个目的的
