[SC总结] OG60 "be of"结构

  owning and living in a freestanding house on its own land 是动名词短语作主语，谓语用单数

   分词只能作定、状、补、表，不能作主语

同意。

关于这个owning and living 用单数的问题，偶也疑惑过。 不过显然EST认为是一个冬冬。 不画线部分就有提示。

偶以前还有一个疑问, It 代owning and living 妥否？ 后来想可能 owning and living 基本算名词性质的冬冬了。

1,带and的并列主语一般与复数形式的动词搭配。

2，当并列主语指同一事或同一概念，谓语动词可用单数：

The number and diversity of British newspaper is considerable.

War and peace is a constant theme in history.

The capacity and efficiency with which your body can perform depends on the degree of development of both your muscular and organic power through regular exercise.

偶有两个疑问：

owning and living in a freestanding house on its own land is still a goal of a majority of young adults, like that of earlier generations.
这里its指代对象逻辑上有，是每个young adult. 但是语法上好像没有？？

According to a recent poll, owning and living in a freestanding house on its own land is still a goal of a majority of young adults, as it was of earlier generations

还有个指代的问题。这里it是earlier generations的东东，怎么指代了现在young adult的东东？？it指代提到的东东，that指代一类东东。好像只是个effectiveness判据，请NN指点

1，我说的结论来自《新编英语语法，章振邦》P975。我想许多这样的用法都是习惯用法，我们只能去记忆，没法说出为什么。我觉得ETS有些题也出的不严密。

2,its可能指代house's，也只能指代它，但我不知道美国人是怎么理解的。请NN指点。Help! Help!

3，"owning and living in a freestanding house on its own land "本身是一个抽象名词词组，对于年轻人和老一代人都是一样的。所以可以用it指代owning and living in ....。  as it/(owning and living in a freestanding house on its own land ) was (a goal) of earlier generations.

like that of earlier generations  

个人认为 有点隐含着 多代同堂的意义  

不如 as it was of earlier generations   对比清楚
