If we ___ now to protect the environment, we'll live to regret it

问题描述:

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
