一、词性 英语词汇按其功能通常分为十大类。 而根据其句法功能和形式特征， 这十类词又可以分为实 词（notional word）和虚词（form word） 。 名词、代词、动词、形容词、副词都具有实际意义，可以在句子中独立担当成分，所以叫实 词；冠词、介词、连词、感叹词都没有具体意义，不能在句子中担当成分，所以叫虚词。 词类表： 名称 N
oun Pronoun Adjective Numeral Verb Adverb Article Preposition Conjunction Interjection 二、实词的主要用法 1. 名词：表示人、事物或抽象概念的词。在句中可作主语、宾语、表语、补语、定语、同 位语等。 ① The man bought a car yesterday.

( open 为及物动词，后带宾语 the door) We are studying in senior high school now. (study 后没有带宾语，为不及物动词) ⑵ 连系动词（linking verb）是一个表示某物或人的状态或特征的动词，后接表语。 He is a well-rounded student. The dish tastes good. 常用的连系动词有：be, become, get, turn, look, sound, smell, taste, feel, grow, seem, appear, keep, stay 等。 ⑶ 情态动词（modal verbs）: 表示情感态度，在句中不能单独作谓语，只能与实意动词一 起构成谓语部分。它们有 shall, should, will, would, can, could, may, might, must, dare, need, ought to 等。 You should wash your hands before you eat. David can speak several languages. (4) 助动词 ① 协助谓语动词完成各种句型的词叫助动词（auxiliary verbs） 。助动词自身没有词义，不可 单独使用。 He doesn’t like English. ( does 是助动词，无词义；帮助主要动词变成否定意义) ② 助动词协助主要动词构成下列结构或加强语气： a. 时态。 He is singing. (助动词 be 与实意动词的-ing 形式连用构成进行时态) He has married. （助动词 have 与实意动词的过去分词形式连用构成完成时态） He will give us a lecture on how to learn English. (助动词 will 与实意动词连用构成将来时态) b. 语态。 He was sent to England. (助动词 be 与实意动词的过去分词形式连用构成被动语态) c. 疑问句。 Do you like college life? Did you learn English before you came here? d. 否定句。 I don’t like him. e. 加强语气。
Do come to the party tomorrow evening. He did know that. 他的确知道那件事。 ③ 最常用的助动词有： a. c. be 构成进行时态或被动语态； b. have/ has/ had 构成完成时态；
d. shall, will, should, would 构成将来时。 6. 副词 副词是用以修饰动词、形容词、其它副词以及全句的词，表示时间、地点、程度、方式等概 念；在句中常作状语。 It rained heavily. (修饰动词 rain) Learning English well is quite useful. (修饰形容词 useful) He got up early enough to catch the first train. (修饰副词 early) Hopefully, we can get home before dark. (修饰整个句子) 学以致用 猜猜下列各句划线词的词性及中文意思。 1.
