英语中的表语和先行词它们是什么意思啊?在英语中启什么作用?要在什么语言环境下用到表语或先行词呢?有谁知道麻烦告诉我一声哈,在下感激不尽了,
要我说我一时也说不清,举个例子了
This is the man who gave me the book
man 就是先行词,who 是关系代词,一般的关系代词前的词就是先行词,
又如：Thank you for the record that you gave me
record 是先行词,that 是关系代词,
表语常用于英语的主系表句式中（汉语中没有表语）,是主语的一种说明,其意义或可替代主语,或是主语在某一方面的属性.
如：He is a student.
student就是表语.
表语看上去类似（或在汉语中被称为）宾语,但仅仅用于主系表结构.系词通常为be动词,也可以是一些其他含义的说明性动词,如look（看上去）,sound（听上去）等.
：wswss11986 - 大魔导师 十二:你最头上在说些什么啊,那是德语吧,老大,别人要的是英语,不是德语耶!
不过后面就想摸象样了,后面的比我的详细,不过如果你是初学者的话,看我的比较容易懂,他的虽然详细,但是复杂,你会糊涂的

表语只是跟在be动词后，实际上就是至于的补语，和宾语差不多，英语把be动词后的宾语单列出来就成了表语。
现行词是在定语从句中，从句所修饰的名词或代词就称为先行词

这是句子成份的问题
表语:是表明主语的身份,性质性质(如密度\性质\身分....)是要同连系动词一起构成"系表结构"例如:
He is a teacher.teacher就是一个表语,说明he是一位teacher.
It looks nice.天气很好啊!nice就是来表示天气it 的情况!!
先行词:是在定语从句中,被定语从句所修饰的名词.例如:
He i...

He is a teacher who teach our English.在这里定词从句who teach our English是来修饰前面的名词teacher.所以teacher就是一个先行词.
