(2)形式不同。 虚拟语气的谓语动词形式和陈述语气的谓语动词 形式不同， 如虚拟条件句的谓语和真实条件句的谓语就 截然不同。如： If it rains tomorrow，our picnic will be put off. 如果明天下雨，我们的郊游就推迟。 (陈述语气， 说话人认为下雨的可能性很大。) If it rained tomorrow，our picnic would be put off. 万一明天下雨，我们的郊游就推迟。 (虚拟语气， 说话人认为下雨的可能性较小。)

(4)当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时，动 词的形式要根据它所表示的时间作相应调整。 If they had worked hard，they would be very tired now.(从句说的是过去，主 句指的是现在)

情态动词的核心考点
1.can/could和be able to的用法 (1)can和be able to都表示能力，意思上没多大区别。但can只有现在和过去时， 而be able to则有更多的形式。但当成功地完成某一具体动作时，通常不用 could而用was/were able to来表示。这时was/were able to 相当于managed to， 表示经过一番努力，终于能够完成某事。 Her mother can speak French. The wounded man was still able to get to the village and was saved by the villagers in the end.
