动词的种类
动词是表示动作或状态的词,按其词义和在句子中的作用可分为行为动词,连系动词,助动词和情态动词。
1.行为动词
行为动词可分为及物动词 (vt)和不及物动词(vi),及物动词表示动作或状态,有完整的词义,能单独作谓语,后跟宾语;不及物动词表示动作或状态,有完整的词义,能单独作谓语,但后面不能直接跟宾语,如要带宾语则与介词或副词构成短语。
如:

2.连系动词
连系动词本身有一定的词义,但不能独立作谓语,必须与表语一起构成谓语。常用的连系动词有 be, get, turn, become, look, feel, grow, seem, sound, taste, smell等。
如:

3.助动词
助动词本身无词义,不能单独作谓语,只能和主要动词一起构成谓语动词,表示否定,疑问及动词的时态、语态、人称和数等语法特征,助动词有 be,do,have,shall,will等。

a. can与be able to的用法有所区别。can只用于一般现在时和过去时,指本身有能力的"能";be able to用于各种时态均可,指须经过努力而"能"。
b. must与have/has to的用法。must表示说话人主观认为"必须",只用于一般现在时和一般将来时;have/has to表示客观需要,意为"不得不",它可用于各种时态。
