The work he paid special attention to nothing,Why fill in to came for a detailed explanation

This requires you to break the sentence correctly. It should be cut off like this.

Subject: the work he paid special attention to the work that he paid special attention to.

Predicate: came to nothing.

As long as it's right, you'll understand without me explaining, right?

Happy learning! (

Please be prompt, thank you!

The work came to nothing is the main clause.

And he paid special attention to is a definite clause that modifies the work

In other words, to come does not belong to the same group.

First of all, the sentence structure is: the work(he paid special attention to) came to nothing

The parentheses are to modify the work, and after removing it, the work came to nothing This is a complete sentence, which means "the work to which he paid special attention is useless" The to in front of come comes from the phrase pay attention to

the work he paid special attention __to nothing

pay attention to the work, where pay attention to to is a postpositional predicate, and the main clause is the work came to nothing

He paid special attention to is to modify the work, and the work came to nothing is the main sentence.

Sentence B means, "His attention that should have been used for learning is now being used for playing." Removing the definite clause, we can see that the predicate verb of the sentence is "is being drawn to", and to is a preposition, so the gerund is used as the object after the sluggish mode.
