一.实义动词,又叫行为动词,意义完全且能够独立作谓语。 根据能否跟宾语,分为及物和不及物动词。
根据动作发生在时间段还是时间点,分为延续性和非延续性动词。 根据其形式能否做谓语,分为谓语(do, does, did) 和非谓语动词(to do, doing, done)
二.助动词,本身无意义或意义不完全,不能单独作谓语。对实义动词起帮助作用。
1)基本助动词帮助实义动词表达否定,疑问,被动语态和各种时态。 例: The boy is crying. (is 帮助构成现在进行时,与crying构成复合谓语)
He has arrived. (has帮助构成现在完成时,与arrived构成复合谓语)
The house will be sold. (will帮助构成将来时,be帮助构成被动)
Does he like English? (does帮助构成一般疑问句) He doesn’t have lunch at home. (does帮助构成否定句)Trees are planted in spring. (are帮助构成被动语态) 2)情态助动词帮助实义动词表达说话人的情感和态度。 跟DMN(大美女)在WCSM D=dare
M=must(have to) N=need WCSM=will
(
would
)
can(could), shall(should), may(might)
三.系动词,用于构成主系表的基本句式。 例句:
He is a teacher.
Something seems wrong. He appears young.
He kept silent at the meeting. This matter remains a mystery.
,
He fell ill yesterday.
People get angry easily in summer. His face went red.
This kind of cloth feels very soft. This flower smells very sweet.
