10 A: Ouch! I dropped a glass and cut my finger. B: Well, if you ... (be) careful, you ... (not/cut) yourself.

Решение:

1. Well, if you had been careful, you would not have cut yourself.

Объяснение:

Это третье условие (Third Conditional), так как речь идет о сожалении о прошлом. Используется Past Perfect (had been) в if-clause и 'would have' + Past Participle (would not have cut) в main clause.
