1、精选优质文档-倾情为你奉上句子是按照一定的语法规律组成的，表达一个完整的意义。一个句子一般由两部分构成，即主语部分和谓语部分，这两部分也叫做句子的主要成分。句子的次要成分包括宾语，定语，状语，表语等。句子成分是句子中起一定功用的组成部分。1）主语：是一句的主体，是全句述说的对象，常用名词，数词或代词担任，一般放于句首。如：Students study. (学生学习。)We are friends.(我们是朋友)这两句话中单词students是个名词，we是代词，它们在句中做主语。2）谓语：是对主语加以陈述，表示主语的行为或状态，常用动词或者动词词组担任，放在主语的后面。如：Students s
2、tudy. (学生学习。)We are friends. (我们是朋友)这两句话中单词study和are都是动词，study叫做实意动词，are叫做be动词，它们在句中作谓语。3）宾语：表示行为的对象，常由名词或者代词担任。放在及物动词或者介词之后。如：They are teachers. ( 他们是老师。)I play with him. (我和他一起玩。)这两句话中单词teachers是名词，单词him是带词，它们在句中作宾语。4）定语：是用来说明或者限制名词的成分，常用形容词或者相当于形容词的短语或从句担任。形容词放在名词之前，相当于形容词的短语或从句放在名词的后面。如：This is

(这些学生学习努力。)I often write to him. (我常给他写信。)The bag is too heavy. (这个书包太重了。)这三句话中单词hard 和often修饰的都是动词，第三句话中单词too修饰的是形容词，它们都作状语。
4、）表语：用来说明主语的性质或状态。一般由名词或者形容词担任。如：This table is long. (这个桌子是长的。)通常情况下,主语和宾语前的成分是定语，谓语前的成分是状语，时间词作状语放在句子后面。句子的成分分布如下：（定语） 主语 （状语） 谓语 （定语） 宾语 （状语）如：(The tall) boy (often) go (to the big) zoo.(The happy) child - went (his) home yesterday.请分析下面句子的结构说出各个成分1）I have two elder sisters. （我有两个姐姐。）2) They dont s
