一、those who型
当代词 those 后接定语从句时，定语从句通常用关系代词who来引导。如：

Thanks are due to all those who took part. 向所有参加的人表示感谢。

二、those whom型
当 those 后引导定语从句的关系代词用作宾语时，可以省略作宾语的whom。如：
He could imitate in speech or writing most of those he admired. 他能模仿大多数自己崇拜的偶像的讲话和写作风格。
Eric was a gifted teacher beloved by all those he taught over the years. 埃里克是位天才的教师，多年来他一直受到所以学生们的热爱。

三、those whose型
当 those 后引导定语从句的关系代词用作定语且表示所属关系时，关系代词用 whose。如：
The syndrome is more likely to strike those whose immune systems are already below par. 这种综合征更容易对那些免疫系统已经低于正常水平的人构成威胁。
四、those that / which 型
许多人认为，those 后的定语从句只能用 who 来引导，不能用 that 或 which，其实是误解。
1. 当先行词 those 指人时，其后的定语从句可以用 who 来引导，也可以用 that 来引导，但以用 who 引导为普通。如：
None are so deaf as those that will not hear. 最聋的人莫过于不愿听别人意见的人。
His simple message was that God will punish those that do evil. 他的意思非常简单：上帝将会惩罚作恶者。
2. 当先行词 those 指事物时，其后的定语从句不可以用 who 来引导，可以用 that 来或 which 来引导。如：
The votes in the marginals are those that really count. 边缘席位的选票才是最关键的。
The design of the new house is similar to those that have already been built. 这栋新房子的设计与已经建好的那些房子相似。
We must try to find out those which may be attacked most easily. 我们必须设法找出容易受攻击的东西。
You are asked to indicate those which most describe your personality. 要求你指出最能表明你性格的那些方面。
另外注意，those后可接定语从句，但these后习惯上不接定语从句。
