主语从句 知识讲解 who 和whoever的区别
To improve the quality of our products,we asked for the suggestions______had used the products. (whoever/who/whichever/which) 答案是whoever，为什么不是who呢？ 另外， class regulations require____is the last to leave the classroom turn off all the lights. (who/whoever)请问，应选择哪一个？ who与whoever到底有什么区别？
"两道题目都使用whoever。 who 和whoever都可以引导主语从句，只能置于句首，不能用形式主语it代替。它们也都有“谁”的含义， 但能否互相替代呢？请观察下列句子并选择正确选项： (A) ________ leaves the room last ought to turn off the light. A. Anyone B. Who C. Whoever D. No matter who (B) ________ will give us a talk is unknown to us all. A. Whoever B. Who C. Anyone D. No matter who 句(A) 的正确选项为C。whoever 的含义是：the person who... 或anyone who... [无论(不管)是谁]，前者特指，后者泛指。句(A)的意思是：无论谁最后离开房间都应该关灯。又如： Whoever (Anyone who) breaks the law should be punished. 不管谁违法都应该受到惩罚。 Whoever (The person who) told you it was lying. 无论谁告诉你的都是说谎。 句(B)的正确选项为B。who虽然也可以引导主语从句，但它常保留本身疑问的含义，即“谁”。句(B)的意思为：对我们大家来说，谁给我们讲话还不知道。又如： Who will go with us has not yet been decided. 谁和我们一起去还没决定。 Who will be sent abroad is unknown. 还不知道谁将被派往国外。"
