主語從句：用作主語的從句叫主語從句。引導主語從句的關聯詞有從屬連詞、疑問代詞、疑問副詞、縮合連接代詞、縮合連接副詞等。例如：That he finished writing the composition in such a short time surprised us all. Whether we will go for an outing tomorrow remains unknown.
表語從句：用作表語的從句叫做表語從句。引導表語從句的關聯詞與引導主語從句的關聯詞很多都一樣，有that，what，who，when，where，which，why，whether，how，whoever，whomever，whichever，whatever等，還有如because，as if，though等。例如：He has become a teacher.
賓語從句：在句子中起賓語作用的從句叫做賓語從句，賓語從句分為三類：
動詞的賓語從句：例如I heard the news. （I是主語，heard是謂語動詞，the news是名詞作賓語，這里的news就是動詞heard的賓語從句的內容）
介詞的賓語從句：例如He said nothing about the plan. （He是主語，said是謂語動詞，nothing是代詞作動詞的賓語，about是介詞，the plan是名詞作介詞的賓語，plan就是介詞about的賓語從句的相關內容）
形容詞的賓語從句：例如某些有動詞意義的形容詞后的賓語從句
同位語從句：它的作用相當于名詞，對前面的名詞（短語）加以補充說明或進一步解釋，相當于一個表語從句，它們之間的關系就是同位關系，即主表關系。其關聯詞多為that。例如：I heard the news that our team had won. I had no idea that you were here.
定語從句：其作用是作定語修飾主句的某個名詞性成分。
引導定語從句的關聯詞有who，whom，whose，that，when，where，why和which。在非限制定語從句中，只可用which，who，whose，where，when，如果指代前面整個句子，多用which。例如：Those who are in favor of the proposal are expected to discuss it in detail after the meeting. There are many organizations whose purpose is to help the homeless. The only thing that matters to the children is how soon they can have their holiday. These are the very points that puzzle me.
