在英语中谓语与系动词+表语有何区别？有的书上就说二者没有什么区别，例如：

SVP (主语+谓语+表语） 

He is tall. 

He is a student.

is 是系动词，怎么叫表语呢？还是系动词+表语被称作谓语呢？

主系表的本质：主语+（系动词+表语），在英语语法中，为了让学习者区分主谓结构，而把（系动词+表语）另外归为一类句子结构。也就是说，在主系表结构中，谓语是由：系动词+表语构成的

解答如下：

主语+系动词+表语“简称为主系表”，系动词由这些词充当"be,seem,look, get, appear, 等，备注：有些语法书上，把系动词+表语，称作为句子谓语部分，即，句子谓语由，系动词+表语构成句子，说成为：主系表结构，系动词不能单独作谓语，必须要和表语一起做谓语

主系表结构句子中，表语的作用是“和系动词一起说明主语，身份，特征，以及状态成分”.

(1)名词作表语“说明主语身份/职业”（谓语=系动词+名词）

She is a doctor.

You are a teacher.

I am a bus driver.

We are students.

(2)形容词作表语“说明主语特点/特征”（谓语=系动词+形容词）

She is beautiful.

I am handsome.

He is strong .

We are honest.

(3)副词作表语“说明主语状态”

She is away.

The light is off.

The film is on.

We are here.

(4)介词短语作表语“说明主语状态”

She is in the room.

They are in the classroom.

Everything is in good order.

I am beside Tom.

(5)不定式作作表语“说明主语的内容”

Her job is to wash dishes.

My task is to protect you.

The duty of the police is to keep order.

Our mission is to safeguard our motherland

(6)动名词作表语“说明主语内容”

Her job is taking care of the baby.

My job is doing my homework.

Mary's job is cleaning the room.

His job is teaching English.

(7)从句作表语：“说明主语的内容或者原因”

The question is that we don't have so much money.

The question is how we will get so much money.

The question is where we can find him.

This is because he doesn't like you

主语+谓语+宾语 简称主谓语宾语，谓语由行为动词充当：write, speak, say, talk等，在语法上，句子谓语由行为动词充当，称作为：主谓结构.

(行为动词可以单独冲动句子谓语）

She speaks English.

She likes English.

(1)She(主语)+is(系动词)+beautiful(表语)

(2)I (主语)+love(谓语)+you（宾语）

主语：I

谓语：love

宾语：you

那么我们来变一下。

(1)主语的扩展

I, full of creativity and imagination, love you. 

（这句话通过给主语添加形容词短语full of creativity做后置定语，使其变复杂了）

I, the most considerate and handsome boy in the world, love you. 

（这句话通过给主语添加同位语the most considerate and handsome boy in the world使其变复杂了）

I ，who is the most considerate and handsome boy in the world ，love you. （这句话通过给主语添加who引导的定语从句who is the most considerate and handsome boy in the world，使其变复杂了）

(2)谓语的扩展

I love you with heart and soul. 

（这句话通过给谓语动词love添加介词短语with heart and soul作状语，使其变复杂了）

 I love you more than I can say. 

（这句话通过给谓语动词love添加比较状语从句more than I can say作程度状语，使其变复杂了）

 I love you, willing to do everything for you. 

（这句话通过给谓语动词添加分词短语作伴随状语，使其变复杂了）

(3)宾语的扩展

 I love the twenty-year-old you.

（这句话通过给宾语添加形容词the twenty-year-old作定语，使其变复杂了）

 I love you, the smartest girl in the world.

（这句话通过给宾语添加名词短语the smartest girl in the world作同位语，使其变复杂了）

 I love you who is the smartest girl in the world.

（这句话通过给宾语添加who引导的定语从句who is the smartest girl in the world做定语，使其变复杂了）
