1、句子成分一概念句子是由词按照一定的语法结构组成的。组成句子的各个部分叫做句子的成分。句子的成分包括：主语、谓语、表语、宾语（直接和间接宾语）、宾语补足语、定语和状语。主语和谓语是句子的主体部分（在英语中，一般句子必须有主语和谓语），表语、宾语和宾语的补足语是谓语里的组成部分。其他成份如定语和状语是句子的次要成分。二句子成分分类1主语主语是谓语讲述的对象，表示所说的“是什么”或“是谁”。一般由名词、代词、不定代词或相当于名词的单词或短语来充当，也有从句充当的现象。大多数主语都在句首。名词作主语The classroom is very big. 代词作主语We work in a big fac

It took two work
3、ers about three months to build the house. 2谓语谓语时用来说明主语“做什么”、“是什么”或“怎么样”，谓语必须是动词，谓语和主语在“人称”和“数”两方面必须一致。如：He is very generous. She looks very smart and cool We have finished the job. He can speak German. 3表语表语说明主语“是什么”或“怎么样”，由名词、形容词、介词、副词、不定式及相当于名词的词或短语来充当。形容词作表语You look younger than before. 名词作表语My

5、orgives others for their mistakes. 代词做宾语He often helps me. 不定式作宾语He likes to sleep in the open air. 动名词作宾语The Americans enjoyed living in China. 从句做宾语I believe that they can finish the work in time. 直接宾语和间接宾语及物动词作谓语时，后面要跟宾语，宾语分直接宾语和间接宾语。直接宾语是人。间接宾语是物，如：We brought them some food. 间接宾语可以放在直接宾语后面，但必须加t
