一个英语主谓一致+定语从句问题 Every student as well as some teachers who is to visit the museum are asked to be at the school gate before 7.30 in the morning为什么第一处要用is第二处要用are?我知道第一处的主语是every student要用is可第二处不应该也用is吗? 答案说先行词是teachers要用are,为什么teachers是先行词呢
本题Every student是主语as well as some teachers作插入语修饰Every student,所以第一处要用is。 后面用到一般被动语态用法。(be+done),Every student as well as some teachers指每一个学生和老师,这里是复数概念,所以用are asked。
