英语中的实义动词、助动词、情态动词、介词、副词,有哪几个?把实义动词、助动词、情态动词、介词、副词都举例说明.如：实义动词有：eat、walk等,助动词有do、does等.

实义动词：很多。例如eat walk drink take have do sleep fly sweep drive ride 等等
助动词：do(does,did,done，构成疑问句与否定句)be（is，am，are，was，were，been，构成系表结构）have（has,had,had,构成完成时）
情态动词：can,may,must,should,ought to,could,have to,might,shall,will, would
介词：in,on,out,off,under,below beyond,for,of,behind,into,onto,through,across等等
副词：quickly,smoothly,slowly,fast,early,easily,hard,well,badly,carefully,often,always,sometimes,等等

楼上的举例已经很详实了，我就只是补充一下吧。
情态动词ought ot=should基本上可是换用。楼上一对一对的，后者是前者的过去式。
助动词：do, does, did,done,have。am is are是be动词，后面的是过去式was were.过去分词been
介词的用法很多，最好查阅书籍，词典。很多动词后面跟固定的介词有不同含义

实义动词；eat,run.drink.look.listen.等情态动词can could will would shall should may might must need ought 助动词 am is are was were been do does did done介词 in on to under below up for off down 等副...
