Question

_______ who have questions to ask,raise you hands .

Answer 1

答案：B

翻译：那些有问题要问的人,请举起手来.

1.主句为：___ raise your hands.

而定语从句who have questions to ask,修饰主句主语（先行词）即选项.

2.不难看出,从主从句谓语动词的数即知选项必须是复数概念,否则主句谓语动词要用raises,而定语从句的谓语动词要用has.

定语从句中,关系代词who等于先行词即选项,并充当从句的主语.

3.而答案中的ACD都是单数概念,排除.

另：those做先行词并指人时,定语从句的关系代词一般只能用who,这是一个固定用法,记住哦.
