请问哪里错了It can be difficult to learn *.
答
Respectfully disagree. For most other people (non-*s), the statement of "It is difficult to learn *" is true, however, for those who live close to Tibet, it's entirely possible that it is not difficult for them to learn *. Hence, "It can be difficult to learn *." in a different setting. An analogue, John is a good guy (implying he's not difficult) but he can be difficult sometimes.
