I've read a book showing some tips about TOFLE exams. It said that we can't use an adverb after " to + infinitve" like the following sentence :
People should try to perfectly finish their work
What do you think? Is it right?
But I read a webpage which did use an adverb after " to + inf"
".....Another important feature is a wizard like interface that enables the users to quickly set up downloading rules.........."
Please, tell me what is right from wrong. Thanks
Hello, Kenduong Emotion: smile
In your question, you mentio "to-infinitive + adverb", yet in your examples the construction is "to + infinitive + adverb" (this is called in English "split infinitive" since the particle "to2 and the main part of the verb are separeted by an adverb).

You can use an adverb after a to-infinitive that does not take a direct object, as in:
"I have learned to drive well."
If the to-infinitive takes an object, then it might be better to place the adverb after said object:
"I have learned to drive trucks well."

The "split" infinitive is often considered "bad style". For example, some authors will say that a sentence such as:
"He was wrong to suddenly leave the country."
should be corrected as:
"He was wrong suddenly to leave the country."
"He was wrong to leave the country suddenly."

However, I've seen the split infinitive used even in grammar books, in constructions such as "To fully understand the concept..."

At the same time, there are cases in which the split infinitive seems the right option in order to avoid clumsiness or ambiguity:
"I have tried to consciously stop worrying about this."
If you changed the position of "consciously" in the sentence, then the meaning of the sentence might become ambiguous or even change.

If you are going to take that examination, however, I would advise you to follow the tips given in the book, even if only for the exam.

I hope it helps.
