1、一、主系表结构主谓宾=主语+实义动词+宾语，be是系动词，不能用于主谓宾中。主系表=主语+系动词(最常见的是be，还有“五感”feel、look、sound、smell、taste和其它动词如become、grow等）+表语（名词、代词、形容词、时间地点副词、介词短语、表语从句等）。第1页/共19页如I am a boy.这句话中没有宾语，属于主系表，I是主语，系动词am是谓语动词，a boy是表语，系动词和表语合起来作谓语。由此可见在主系表中，谓语谓语动词；而在主谓宾中，谓语=谓语动词，如I love my parents.总之，系动词和宾语是不共戴天的仇人，誓不两立。系动词后面接的是表语，

2、而宾语前面接的是谓语。第2页/共19页所谓主系表结构就是英语句子中的主要成分是主语、系动词和表语。主要用以说明主语的特征，状态，身份等。定义 主系表（S+V+P）：1.主语（Subject）2.系动词（Link verb）3.表语（Predicative）第3页/共19页所谓主系表结构就是英语句子中的主要成分是主语、系动词和表语。主要用以说明主语的特征，状态，身份等。1.主语（Subject）：主语是一句话的中心，表示所说的是谁或是什么，其位置一般放在句首。英语中主语一般不省略。主语主要由名词、动名词、代词或起名词作用的短语或从句来充当。例如：Li Lei is a Chinese boy.（

3、Li Lei 是名词，作主语。）He is from England.（He 是代词，作主语。）Feeding the birds is my hobby.（“Feeding the birds”是动名词短语，作主语。）What she said is right.（“What she said”是从句，作主语。第4页/共19页2.系动词（Link verb）：系动词本身有一定的词义，但不能独立作谓语，必须和句子中的表语一起构成谓语。简单地说，将主语和表语联系在一起，并构成一个完整句子的动词就叫做系动词。目前学到的系动词有 be，feel，look，sound，taste，smell 等。例如

4、：This flower is beautiful.I felt very tired.You look worried.It tastes delicious.第5页/共19页常见的系动词（1）表示特征和存在状态的be,feel,look,smell,taste,sound.（2）表示状态延续的keep（3）表示状态变化的become,get,turn,go,come第6页/共19页 3.表语（Predicative）：表语是用来说明主语的身份、特征或状态的。它又叫作主语补足语。表语位于系动词之后，主要由名词、代词、形容词、数词、副词、介词短语、分词（短语）或动名词（短语）等来充当。例如：I

5、 am fine.（fine 是形容词，作表语）He is a boy.（boy 是名词，作表语）Five plus two is seven.（seven 是数词，作表语）We are here.（here 是副词，作表语）He is not at home.（“at home”是介词短语，作表语）My hobby is reading.（reading 是动名词，作表语）第7页/共19页二、There be 句型 there be：表示某地有某物，指没有生命的物体有。例如：There are many books in the schoolbag.have/has:表示有生命的人或者动物有
