3

Its dish of milk,
And smooth its coat 问题3.这两句的句子成分
To shine like silk.
4
And on my knee
It oft will sit;

Answer 1

1, by the fire是状语， it loves to sit 主谓宾（不定式作宾语）
It loves to sit by the fire.

2, there will sit 是并列谓语，由but连接。 there是把状语提前了，句子顺着看是：
It scarce(文学中作副词）will stir, but will sit there all day and purr.
它几乎不走动，除了整天坐在那里咕噜。

3， 2个并列谓语： I bring its dish, and smooth its coat
to shine 状语， 也就是 smooth its coat to some degree
每天我给它一份牛奶，并将它的毛捋到丝般顺滑。
