My Hiknow student C.C. asks:
I have a doubt about the question:
I'm not sure of the grammar here, because I would ask:
Your sentence is correct. And so is the other one. They're both right, just different structures.
I believe the grammar of the questions might become clearer if I give you not only a grammatical explanation of the questions, but also example answers to the questions in the form of complete sentences.
I'll use a colour code to help demonstrate the grammar.
In Question 1:
In Answer 1,
In Question 2:
Infinitive phrases (more info) can be used many ways. Here it's the indirect object of "does... need".

In Question 3:
Participle clauses (more info), using either past participle (usually -ed) or present participle/gerund (-ing), are similar to relative clauses, giving more info about another word in the sentence.
In Answer 3:
Oh boy, I just though of a fourth way!
In Question 4:
In passive voice (more info), the subject receives the verb, so there is no direct object.
In Answer 4:
So you see, there's more than one way to ask a question! I hope that makes clearer for you these different possibilities.
