情态动词主要有：can/could;may/might;must/ought; need; dare/dared; shall/should; will/would
1.情态动词不能单独作谓语,必须和实意动词或连系动词的原形（有时和这些动词完成和进行式）一起构成谓语
例如1：Wemust study hard .
我们应该努力学习（must+不带to 不定式study充当谓语）
例如2：Hecan speak a little English .
他会说一点儿英语（can +不带to 不定式speak充当谓语）
例如3：Hemust have gone home.
他准是/一定是回家了（must+不带to 不定式havegone 充当谓语）
例如4：Hemust be waiting for us .
他一定是在等我们（must+不带to 不定式bewaiting 充当谓语）

例句1.Ican write in English.
我会用英语写
例句2.Hecan write in English .
他会用英语写（不必说：Hecans write in English )
