If we ___ now to protect the environment, we'll live to regret it
If we don’t act now to protect the environment, we'll live to regret it ? 一句话只有一个谓语动词, act
protect live 怎么有三个谓语动词? 我英语很烂,请高手帮忙

楼主先别急,一个句子一个谓语动词没错.先把句子拆开,逗号前if引导从句,act为从句谓语.逗号后为主句,live为主句谓语.to protect和to regret是非谓语动词做补语.
希望楼主采纳,有问题可以继续问
