Question

①She is one of the girls who _have__? (have) been to paris?选填形式？has 还是have ?

②Either you or one of your students is to attend the meeting that __is__due tomorrow.为什么一个用have 一个用is,怎样区分这两道题？

Answer 1

1.who 引导的定语从句的先行词是girls 而不是one，因此要用have
She is one of the girls. The girls have been to paris.
She is one of the girls who have been to paris
2. either ...or...就近原则，one of your students你学生中的一个，one做主语，所以用 is;
one of your students is to attend the meeting that __is__due tomorrow.

Answer 2

她是去巴黎的女孩子之一 who引导的从句修饰the girls 故而用have

你或者是你的同学中的一个区参加会议，明天到期
that引导的句子修饰the meeting

Answer 3

1.have。who引导的是定语从句，先行词是girls，所以要用have。
2.is。that引导的是定语从句，先行词是the meeting，所以要用is。

Answer 4

1. have ,who 引导的定语从句修饰GIRLS
2. that 引导的从句修饰meeting .
