Can the verb -Help be followed by a verb in to or basic form?
Below are the sample sentences:
1-My teacher wanted to know who helped me write the compositions.
2-We all helped him fill out the application form
3-He helped me to pass my exam
4-Sally said he would help us to move the furniture.
'Help' is one of those rare full verbs that can be followed by a bare infinitive. When I was younger, this was more true of AmE, but it is now firmly entrenched in BrE as well. All your sentences are fine.
