I ___ speak English well now but I hope I ___ speak next year. ?

The question "I ___ speak English well now but I hope I ___ speak next year." requires us to think about the speaker's current ability to speak English and their future aspirations regarding that ability.

Option B: "can’t / shall be able to" is the correct choice because it effectively captures the contrast between the speaker's current inability and future hope. The phrase "I can’t speak English well now" indicates a present difficulty or lack of proficiency, which aligns with the speaker's situation. Meanwhile, "I hope I shall be able to speak next year" conveys a positive anticipation about improving language skills in the future.

Let’s consider the other options:

- Option A: "could / can" suggests past capability and a current ability, which is not applicable here since the speaker cannot speak well now.

- Option C: "must / shall have to" implies obligation rather than ability, which is not relevant to the context of speaking proficiency.

- Option D: "may / may" suggests uncertainty, but it does not indicate a clear separation between current ability and future improvement.

Thus, option B not only delineates the current lack of ability but also expresses an optimistic outlook for the future, making it the most appropriate choice.
