1.She  2.keeps  3.some of the most lovable little rabbits you ever saw   4.in the garden.

1.主 2.谓 3.宾 4.状

1,2,4三个成分加起来都不如一个宾语长。

因宾语太长，为了句子匀称，把4提前，结果使谓语和宾语被状语分隔：

She keeps in the garden some of the most lovable little rabbits you ever saw.

关于这个句子：Never say anything behind a person’s back that you won’t say to his face.

因定语从句太长，为了句子匀称，把介词短语提前，结果使定语从句和先行词被状语分隔。
