You must finish the homework first. b. The road is wet. It must have rained last night. 2. 情态动词通常后接动词原形。而且情态动词没有第三人称单数的词形变化，即没有-s形式、也没有-ing形式和-ed形式。 3. 情态动词有过去时形式，如can/could, may/might，will/would, shall/should但在许多场合中过去时并不表示过去。 例如：a. Could you leave a message please?　b. Would you like to go to the party with me? 难点释疑 can/could与be able to用法比较 在肯定句中，都用于表示具有某种能力，而be able to可用于各种时态，相当于manage to do或者succeed in doing。因此，can/could和be able to不能互换。例如：a. I can sing many English songs. b. We were able to return to our campsite before the heavy rain. c. He was able to swim across the river yesterday. 在否定句中，can/could
