I know all the three sentences below are grammatically correct, but sentence 3 sounds a bit awkward to me. Is it only me that feels this way?
- Speaking English is not difficult.
- It’s not difficult to speak English.
- To speak English is not difficult.
When an infinitive is used as a subject of a sentence, it almost always sounds a bit unnatural to me.
To watch baseball games is fun.(unnatural)
Watching baseball games is fun. It's fun to watch baseball games.(better)
The only example that sounds natural to me is “To err is human, to forgive divine” by Pope, because I suppose it’s like a proverb.
Is it common to use an infinitive as a subject? I don’t think so, but if so, could someone give me some examples that sound natural?
