6) Kate (not pass) the exam, unless she (work) hard. (1)

Kate **will not pass** the exam, unless she **works** hard. *Explanation: This is a first conditional (using 'unless' instead of 'if not'). It expresses a real or possible situation in the future. We use 'will not' in the main clause, and the present simple in the 'unless' clause.* *Перевод: Кейт не сдаст экзамен, если она не будет усердно работать.*
