an that is reading the newspaper over there?
　　Which of us that knows anything does not know this?
　　(2) 当先行词被形容词最高级或序数词所修饰时。如：
　　He is the greatest man that has ever lived.
　　(3) 当先行词被the only, the very, the last等词所修饰时。如：
　　She is the only person that understands me.
　　6. 当先行词被the same所修饰时，关系词既可以用as，也可以用that。在表示具体事物
　　时，有时两者有一定的区别。一般说来，表示同一种类多用as，表示同一事物多用that。
　　如：
　　This is the same instrument that I used yesterday. 这就是我昨天用过的那台仪器。
　　This is the same instrument as I used yesterday. 这台仪器跟我昨天用过的那台一样。
　　在抽象概念上，同种类和同一事物是没有绝对区别的，所以两个词可换用：
　　I have the same opinion as / that you have.
　　这里要注意的是：
　　（1） 使用as时，它引导的定语从句中的动词可以省略，但使用that时，定语从句中
　　的动词不可省略。如：
　　Women received the same pay as men.
　　Women received the same pay that men received.
　　(2) 在“the same…that”结构中，that只是用来加强语气，强调“相同”。that可以省去而不改变句子原意，甚至连名词前的same也可以省去。如：
　　This is the same instrument that I used yesterday.
　　= This is the same instrument I used yesterday.
　　= This is the instrument I used yesterday.
　　但在“the same…as”结构中，same和as都不能省略。
　　(3) 当“the same…that”结构中的that作为关系副词用时，不可以直接与as互换。
　　如：
　　He lives in the same building that I live.
　　= He lives in the same building as / that I live in.
　　Shall we meet at the same place that we last met?
　　= Shall we meet at the same place that / as we last met at?
　　7. 当先行词前有such, so, as时，关系词应当用as。如：
　　A wise man seldom talks about such things as he doesn’t understand.
　　He spoke in such easy English as everybody could understand.
　　At this time of the day, all buses and trolleys have to carry as many passengers as they can.
　　It is so easy a book as every schoolboy can read.
　　Let’s discuss such things as we can talk of freely.
　　另需注意：
　　This book is written in such easy English as beginners can understand.（定语从句）
　　This book is written in such easy English that beginners can understand.（结果状语从句）
