表示部分与整体概念的代词有both, all, neither, none, either,

some, any, most, few, one, half等。

3．the＋名词＋of＋关系代词

此结构用来代替“whose＋名词”，也可用“of which the＋名词”。

四、the way后的定语从句的关系词

way表示“方法，方式”时，其后的定语从句有两种情况：

1．the way的关系词在定语从句中作主语或宾语时，用that和which均可，作宾语时可省略。

The way (that/which) he thought of to prevent the air pollution was very good.

他想出的防止空气污染的方法非常好。(关系词代替the way在定语从句中作thought of的宾语)

2．the way的关系词在定语从句中作方式状语时，用that或in which均可，现代英语倾向于省略关系词。

At one with nature PPT，第三部分内容：语境即时活用

The dog and the shadow

It happened that a dog had got a piece of meat and was carrying it in his mouth to some place in which he can eat it in peace. As he crossed a plank lying across a running brook, he looked down and saw his own shadow reflected in the water beneath.Thinking it was another dog with another piece of meat, he made up his mind to have that also.So he made a snap at the shadow in the water, but as he opened his mouth the piece of meat fell out, dropped into the water and was never seen more.

点评：文中第一句中的“in which he can eat it in peace”为“介词in＋which”引导的定语从句，其中in which可以替换成关系副词where。
