主题 5：用名词修饰名词

The conference hall was built three years ago

在一个句子中，把名词用作形容词，放在另一名词之前是很常见的，他们的关系大致如下：
1， 表示第二个名词由某种东西或者材料制成（My grandfather used to have a glass bowl like that.）
2， 表示地点（When he was cleaning the room, he broke the table lamp which was given to him as a wedding present by his uncle.）
3， 表示时间 ( When do you usually have your afternoon tea?)
4， 表示用途或目的( He couldn’t find his car keys when he got to the parking lot.)

要注意名词用于另一名词之前作形容词，即使其本身含义是复数的，也几乎总是用单数。
Those men in black suits were house agents。

主题 6：限定词+名词+of+所有关系词结构
A friend of mine will pick me up near the subway entrance.

无论在书面语或口语中，上述结构都经常使用。

That policeman is a friend of mine.

请注意下列情况
1， of后一般跟名词性的物主代词，如：yours, ours, 等
2， of后可跟名词的所有格
A colleague of John’s had an accident yesterday.
如名词本身是s结尾的，只需加上’即可。
A relative of the Blues’ went to Hongkong on business.
3, 有时of后也跟代词的宾格，但意思上有所不同。试比较下列两个句子：
This is a picture of mine.
这是我（收藏）的一张照片。（是我所有，但照片里不一定有我）
This is a picture of me.
这是我的照片。（照片里就是我本人
