which kind of infinitive

[AUTOMOON]

----- " The trees in that area were found_____slowly from the effect of acid rain."
a A to die B dying

The referential answer is A, but why not B?

I think "I found him standing under the tree." is right. Someone explained that when in passive voice, you should add "to " in front of the verb.
He added that you can also replace "to die"with "to be dying" ,but you should never use present participle .
Does he make any sense?

Does passive voice make a difference here?

THANKS~~~~~~

I think you can use 'dying' as well, but they're different. If you say 'found to die', it means that the trees are dead, and this was the reason. If you say dying/to be dying, they were not dead when someone discovered the problem.

[AUTOMOON]

According to what you post, we can also use structure like find Verbing in passive voice, without adding to be in front of the Verbing ?

I can't see why not. Formally, the 'to be' is more likely to be included to show the reason, but 'dying' alone would describe their condition.

This can be helpful to you. Please correct me if I am wrong.

Infinitive can be used to join two sentences. In a sentence only one tense can be used, while other becomes "to be". It carries no tense, but tell us about noun, verb, adjective. Eg.

1) It was found that the trees in that area were dead.

The trees in that area were found to be dead.

2) It was found that the trees in that area were dying.

The trees in that area were found to be dying.

3) It was found that the trees in that area will die.

The trees in that area were found to die

As found has come in between above sentences thats why to be is added.

Trees are dying.
Trees will die
Trees will be dead
