To complete the sentence "At first I ___ skate well, now I ___," we need to determine the correct verb forms that fit the context.
Let's analyze the given options:
A:
couldn’t / can
This option provides the correct verb forms. "Couldn't" indicates the past inability to skate well, and "can" indicates the present ability to skate well. Therefore, option A is the correct answer.
B:
may / can
This option does not provide the correct verb forms. "May" indicates possibility, not ability, and "can" indicates the present ability. Therefore, option B is incorrect.
C:
mustn’t / can
This option does not provide the correct verb forms. "Mustn't" indicates prohibition, not ability, and "can" indicates the present ability. Therefore, option C is incorrect.
D:
should / shouldn’t
This option does not provide the correct verb forms. "Should" indicates advice or recommendation, not ability, and "shouldn't" indicates the negative form of the advice. Therefore, option D is incorrect.
E:
must / needn’t
This option does not provide the correct verb forms. "Must" indicates obligation, not ability, and "needn't" indicates the absence of obligation. Therefore, option E is incorrect.
Therefore, the correct answer is option A: couldn't / can.
