Question

she is the only person i can rely

帮忙看下有没有语法错误,一句英语.
she is the only person that I can find who is able to solve the problem.
请问这句话中的这两个BE动词,哪个需要用到过去式.

Answer 1

这是一个非常典型的双定语从句,就是一个先行词person,后有俩个定语从句来限定that i can find 和 who is able to solve the problem.
我们来分析一下这个句子：
当先行词被修饰ONLY,最高级,序数词等修饰的修饰的时候后面的定语从句必须用THAT来引导,所以后面接了一个that i can find,这是我能找的唯一的人
(the person).who is able to slove the problem,能解决这个问题的唯一的人.
没有任何问题,也许你会问不是说only后面的从句只能用that引导吗?当然,因为前面已经有了that i can find ,后面为了避免重复,将that is able to solve the problem改成了who is able to solve the prolem.
加分呀,一定要加分呀
