句子成分句子的基本句型：主语+系动词+表语（主系表）主语+不及物动词+（其他成分）主语+及物动词+宾语（主谓宾）主语+及物动词+间接宾语+直接宾语主语+及物动词+宾语+宾补你所知道的句子成分有哪些？为什么要学习句子成分？一、可以担任主语的有哪些词或短语？主语是信息表达的出发点，它为理解后面的内容提供了线索和框架。
所以主语是一句话的中心，是一个句子所叙述的主体。
主语通常由名词或代词的主格形式来表示，一般位于句首，谓语动词之前。
Six and three is nine.The rich are getting richer and the poor are getting poorer.To improve the agricultural land needs a lot of money.Collecting stamps is a good hobby.What he wanted to see was an end to all armies of the world.二、谓语谓语表示主语的行为动作或所处的状态。
一个句子主要分两部分，即主语部分和谓语部分。
而谓语部分的中心词是限定动词即谓语动词。
谓语可分简单谓语和复合谓语两大类。
简单谓语有人称和数的变化，有各种时态`语态和语气。
其形式主要有两种：单个动词和短语动词。
复合谓语分为动词性复合谓语和名词性复合谓语。
动词性复合谓语有以下四种形式：1．情态动词+动词原形2．动词不定式3．Be +形容词+不定式4．动词被动语态+主语补足语名词性复合谓语：系动词+表语谓语主要由两种：系动词和实义动词（1）I’m going to see a friend of my father’s tomorrow.（2）Soon we all became interested in the subject.三、表语表语与前面的系动词一起构成复合谓语。

(翻译)We can see them flying along the river.The people had considered him to be a great leader.(翻译)He made London the base for his revolutionary work.（翻译）I found John out when I called at his house.(翻译)What make you in such a hurry?六、当含有复合宾语的句子变成被动句时，原来的宾语补足语就成了主语补足语。
They will be encouraged to eat healthy food.七、定语是名词修饰语。
它和名词一起构成名词短语。
定语就其与被修饰的中心词的相对位置来讲可以分为前置定语和后置定语。
哪些可以作前置定语？哪些可以作后置定语呢？找出下面几个例子中的后置定语。

修饰性状语用来说明句子中谓语动词的动作过程状态等发生和存在的时间地点方式方法程度原因结果目的条件伴随让步比较等。
修饰性状语是谓语的一个组成部分，所以和句子中其他成分关系密切。
