英语句子成分和英语句子结构讲解及练习
一、句子成分
(一)句子成分的定义:

二)主语:
主语 (Subject)

(三)谓语
谓语 (Predicate) 说明主语所做的动作或具有的特征和状态。动词在句中作谓语,一般放在主语之后。谓语的构成如下:
1、简单谓语:由一个动词或动词短语构成。如:
          He practices running every morning.
          The plane took off at ten o’clock.
2、复合谓语:
(1)由情态动词或其他助动词加动词原形构成。如:
        You may keep the book for two weeks.
          He has caught a bad cold.
(2)由系动词加表语构成。如:
        We are students.
注意:谓语与主语在人称与数方面要保持一致。
(四)表语
表语(Predicative)用以说明主语的性质、特征、状态与身份,它一般位于系动词(如be, become, get, look, grow, turn, seem等)之后。
常见的系动词有
状态系动词
可用来表示主语性质或状态,只有be一词,例如:

下列动词只能接动名词做宾语

下列动词既可接不定式,也可接动名词做宾语,但意义不同,如stop, mean, try, remember, forget, regret等。
(六)宾语补足语
英语中有些及物动词,除有一个直接宾语以外,还要有一个宾语补足语(Object Complement),才能使句子的意义完整。带有宾语补足语的一般句型为:某些及物动词(如make等)+宾语+宾补)。
