4、定義： 1. 表語從句（Predicative Clause）：在一個(gè)復(fù)合句中，用一個(gè)句子作為主句的表語成分。說明主語是什么或者怎么樣，表語從句對主句主語進(jìn)行說明、解釋，使主語的內(nèi)容具體化；表語從句只能置于主句之后，而主句的動(dòng)詞只能是聯(lián)系動(dòng)詞；可以接表語從句的連系動(dòng)詞由be, look, remain, seem等。Eg: The problem is puzzling. 這問題令人困惑主語 連系動(dòng)詞 形容詞作表語The problem is when we can get a pay rise. 問題是什么時(shí)候我們可以得到加薪.主語 連系動(dòng)詞 一個(gè)句子作表語-表語從句He has becom

11、why she failed to pass the exam. (why 在表語從句中充當(dāng)原因狀語) 那就是她考試不及格的原因。注意： “That is why.”是常用句型， 意為“這就是的原因/因此”， 其中why引導(dǎo)的名詞性從句在句中作表語， 該句型通常用于針對前面已經(jīng)說明過的原因進(jìn)行總結(jié)，又如： That is why you see this old woman before you know, Jeanne.
