句子结构理解与剖析（同时涉及attempt的理解）

But, in the main, they had thought only of living to themselves in woods and caves and building up an attempt at Old Narnia in hiding.

源于纳尼亚传奇，大概意思我是懂的。不过这里的的意思是？最好能把整个句子的结构给我剖析一下，谢谢老师。

But, in the main, they had thought only of living to themselves in woods and caves and building up an attempt at Old Narnia in hiding.

【结构剖析】

1. 本句主要结构是：think of doing sth. （期望、想要、考虑做某事）

2. of 后面有两个并列的动名词：living to themselves in woods and caves and building up an attempt at Old Narnia in hiding

3. live to oneself：一个人生活；隐居。

4. in the main：习语。总的来讲。

5. build up an attempt at：在......方面打造一种尝试。

6. Old Narnia in hiding：old 指古老传统的；in hiding 作定语，意为“处于隐蔽的；不为外人所知的”。

But, in the main, they had thought only of living to themselves in woods and caves and building up an attempt at Old Narnia in hiding.

【翻译】不过，总的来讲，他们只想隐居在树林中和洞穴里里，试着打造一个隐蔽而古老的纳尼亚。
