Решение:

Нужно поставить глаголы в правильную форму, учитывая условия.

• 1. Most metals rust when they get (get) wet. (Present Simple, так как это общеизвестный факт).
• 2. If I had time, I would play (play) a game of football. (Second Conditional, в главной части 'would' + инфинитив).
• 3. If you train hard, you will get (get) on the team. (First Conditional, в главной части 'will' + инфинитив).
• 4. If I were rich, I would watch (watch) my favourite team play all over the world. (Second Conditional, в главной части 'would' + инфинитив).
• 5. If we trained (train) harder, we would have won the game. (Third Conditional, в главной части 'would have' + причастие прошедшего времени. В условии 'Past Perfect', но здесь похоже на ошибку в учебнике, так как 'would have won' предполагает сожаление о прошлом. Если бы это был Second Conditional, то было бы 'If we trained harder, we would win'. Если бы это был Third Conditional, то было бы 'If we had trained harder, we would have won'. Наиболее вероятен вариант, что в условии пропущено 'had', и это Third Conditional, или же 'would have won' — опечатка, и должно быть 'would win').
• 6. Water turns (turn) to ice when you freeze it. (Present Simple, так как это факт).
• 7. If you had told me you needed help, I would have given (give) it to you. (Third Conditional, в главной части 'would have' + причастие прошедшего времени).
• 8. If I knew how to swim, I would feel (feel) confident in the water. (Second Conditional, в главной части 'would' + инфинитив).

Ответ: 1. get, 2. would play, 3. will get, 4. would watch, 5. trained (или had trained), 6. turns, 7. would have given, 8. would feel
