①名詞性從句，包括主語從句、賓語從句、表語從句和同位語從句；

②形容詞性從句，即我們平常所說的定語從句；

③狀語從句正確翻譯英語句子是英語學習者必須解決的問題。

對于一些結構復雜的難句，我們應當使用技巧使其簡單化。一般來說，可以使用順序法、逆序法、分句法和插入語靈活翻譯法。這些句子結構復雜，邏輯性強，翻譯起來困難相當大。但是，無論多長的句子、多么復雜的結構，它們都是由一些基本的成分組成的。只要弄清英語原文的句法結構，找出整個句子的中心內容及其各層意思，然后分析各層意思之間的邏輯關系，再按漢語的特點和表達方式就可以譯出原文了。在長句的英譯漢實踐中，我們始終應記住英漢在句法結構上的差異，不必拘泥于形式。
