英语主系表结构

答：主系表结构/ 含义主系表结构是指英语句子中的主要成分是主语、系动词和表语。主语是一句话的中心，系词本身有一定的意义，不能单独使用，表语是用来修饰的。

句子中出现系动词的句子就叫主系表.be动词也叫系动词,系动词有三种,amisare三种.系动词一般译成是的意思./...譬如说:Iamateacher.I就是主语,系动词IS就是系.ateacher就是个表语.表语是用来说明主语身份,状态,颜色,形状等等的.那这里ateacher是个老师.那就是用来说明主语I我的身份的.所以这个句子就是个明显的主系表结构....

主系表是一种基本结构，为主语+系语+表语。主语为句子描述的对象，表语描述主语的性质、状况、属性等，系动词起连接主语和表语的连词的作用。一个典型的主系表结构：I+am+xxx，表示“我是...”，其中I是主语，xxx是描述I的性质的表语，be动词am是系语。表语的xxx既可以是名词也可以是形容词。如：I am a student. 我是学生。 I am tired. 我很累。系动词除最基本的be动词外，还包括感官系动词等。如feel、smell、sound等。例：The dish smells dilicious. 这盘菜闻起来很香。 此句也为主系表结构，其中The dish为主语，smells为系动词，意为“闻起来”。dilicious是形容词表语，描述主语The dish性质。

其实就是主语、系动词、表语，这是初级语法知识，是基础中的基础，在洛基英语学习时听老师讲过N遍了，其实不难。一 .何谓主系表结构：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.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.（ 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.）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：This flower is beautiful.I felt very tired.You look worried.It tastes delicious.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 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）
