Namun menurut BBC (http://www.bbc.co.uk/worldservice/learningenglish/grammar/learnit/learnitv226.shtml) tidak ada perbedaan penggunaan "infinitive to" dan "infinitive without to (bare infinitive)" ketika dipakai pada kata "HELP".
Menurut BBC:
Help is a verb that can be used with or without to and with or without an object before the infinitive. When we use it without an infinitive it sometimes sounds more informal.
Compare the following:
- Could you help me to look for my car keys? I can't find them anywhere.
- Could you help me look for my car keys? I can't find them anywhere.
- Would you like to help to cook dinner tonight? It's late and I'm feeling tired.
- Would you like to help cook dinner tonight? It's late and I'm feeling tired.
Perbedaan penggunaannya hanyalah bahwa infinitive to lebih bersifat FORMAL (resmi).
