I am not a native speaker, so understanding a foreign language while living in an environment where people don't speak English very often is a little challenging. Recently, I came across these. I would be glad if you could help with these and explain where to use them?
- He had had to read/swim.
- Could have had to read/swim.
- Would have had to read/swim.
