Answer 1

Honesty is one of the principles by which Andrew lives his life.
請問這邊的which為何出現 by

原因是which是one of the principles的關係代名詞，並用作連接詞，把兩個語意相關的句子連接起來變成一個句子。如：
Andrew lives his lives by many principles.
Honesty is one of them.
當利用關係代名詞連接這兩個句子就可以寫成：
Honesty is one of the priciples by which Andrew lives his life.
這句子的意思是說誠實是安德魯的生活準則之一，而這which所代表的生活準則是要被 Andrew 依循去生活的，所以這裡要把 by 放回在which前面。就如：
I bought this book from that bookstore.
The bookstore is next to my house.
That bookstore next to my house is the bookstore from where I bought this book.
就像這例子中的 where 是 the bookstore 的關代用來做連接詞，由於它原句子中所提的bookstore我是從(from)那裡買到這本書的，所以在連接句中必須還原 from 表示我是從(from) where做 I bought this book 這件事的。

Answer 2

live by為片語...指的是以...過活
這裡指的是他生活的原則
還原成為:
1.Honesty is one of the priciples.
2.Andrew lives his life by the principles.

principles為先行詞
合併成為
=>Honesty is one of the principles which Andrew lives his life by.
在寫關係子句時有一個習慣...
就是當動詞片語中的介系詞寫在關係子句時...
避免放在句末..所以將by往前移
=>Honesty is one of the principles by which Andrew lives his life.

會有by主要是因為live by這個片語的關係

Answer 3

因為by當介係詞用,只是被提到前面而已
原句:Honesty is one of the principles which Andrew lives ''by'' his life.
