5、际意义的动词,能单独做谓语。如 see, ask, like I like bananas.3)助动词:本身没有词义,帮助实义动词一起构成否定句,疑问句。如 do,doesI dont like chicken .Does he like apples ?4)情态动词;本身具有一定意义,但不能单独作谓语,必须和实义动词一起构成谓语。can,能,会, must ,必须,情态动词后一定要用动词原形 。I can speak English .I must find it . 我一定要找到它动词 be 的用法be 的用法口诀我用 am,你用 are,is 连着他,她,它;单数名词用 is,复数名词全
