主系表结构到底是怎么回事啊 能不能多于几个例子啊
就是像有种结构 the school themselves admit that not all children will be successful in the jobfor which they are being trained 这句话中 the are being trained中 哪个是谓语部分
哪个是表语呢 是being trained 还是 trained

Answer 1

此句是一个that引导的宾语从句,在这个宾语从句中,还含有一个分隔式定语从句,先行词是children ,for which they are being trained 是定语从句,所以不能单看 the are being trained.在定语从句for which they are being trained 中,是一个现在进行时的被动语态,所以谓语部分是are being trained .
主系表句子主要成分为主语、系动词、表语
1. 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：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.常见的 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：它又叫作主语补足语,表语位于系动词之后
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）
