特殊疑问词引导的状语从句里谓语动词用什么形式?
如题.
例如：The parents want their sons to be the people who_(is\are\be) successful.

Answer 1

你这个句子里的从句不是状语从句,而是定语从句.定语从句的谓语动词随从句主语变化.如果从句的主语是定语从句所修饰的名词或代词（称作“先行词”）,从句谓语随先行词变化.

顺便指出：你这个句子应该不是出自讲英语人的口或笔下.表达你想表达的意思,人们通常会说：
Parents want their sons to be successful.
或者：
Parents want their sons to be someone who is going to be successful.
或者咬文嚼字一点：
Parents want their sons to be among the people who are going to be successful.
