少用关系代词
学会运用关系代词是你学习英文过程中的一个重要的阶段。学会少用它们则表明你取得了更大的进步。在校对你的作品时，仔细检查一下所有的whichs, whos thats和whoms是否必要。删除不必要的关系代词会使你的文章更精彩。
Example:
Unnecessary: It is a truth that is universally acknowledged that a single man in possession of a good fortune must be in want of a wife.
Better: It is a truth universally acknowledged that a single man in possession of a good fortune must be in want of a wife.
-- Jane Austin
注：被动语态修饰的名词通常不须用关系代词。
