实义动词
实义动词是能独立作谓语的动词，要根据上下文语境来判断动词词义。按其句法作用可分为不及物动词和及物动词。具体用法如下：
1.及物动词可以直接加宾语
2.不及物动词加上介词才可以接宾语P7
3.动词辨析：P8
助动词
助动词本身无词义或意义不完整，不能单独作谓语。它只能帮助实义动词完成某些语法功能，如表示时态、语态，构成否定句、疑问句、简略答语等。助动词主要有be，do，have，shall，will等。具体用法如下：
助动词1.be(am/is/are/was/were)：
(1)构成进行时态:be+动ing
(2)构成被动语态：be+动过去分词
(3)构成系表结构
助动词2.have/has/had：
构成完成时态：have/has+动词的过去分词
助动词3.do/does/did：
助动词4.shall/will+动原(shall用于第一人称,will用于各种人称)
