一、從句變分詞的情況

　　1、定語從句變分詞：

　　定語從句變現在分詞表主動

　　The student who is talking with the monitor is Lucy。/The student talking with the monitor is Lucy。

　　A dictionary is a book which gives the meaning of words。/A dictionary is a book giving the meaning of words。

　　The man who is wearing a white suit is my friend。/The man wearing a white suit is my friend。

　　The bike and its rider that had run over an old man were taken to the police station。/The bike and its rider having run over an old man were taken to the police station。

　　Have you ever visited the Great Wall，which attracts thousands of tourists each year？/Have you ever visited the Great Wall， attracting thousands of tourists each year？

　　定語從句變過去分詞表被動

　　This is the pen which was given by my friend。/This is the pen given by my friend。

　　The animal that/which is lost is a panda。/The animal lost is a panda。

　　2、時間狀語從句變分詞結構：

　　When you think you know nothing，then you begin to know something。/ Thinking you know nothing，then you begin to know something。

　　After we have finished the work，we went home。/Having finished the work，we went home。

　　二、從句變動詞不定式的情況

　　1、目的狀語從句變動詞不定式

　　We used computer in order that we might save time。/We used computer in order to save time。

　　I hire a boat so that i could go fishing。/I hire a boat so as to go fishing。

　　In order that you may create such a picture， you have to possess certain artistic weapons。/In order to create such a picture， you have to possess certain artistic weapons。

　　2、結果狀語從句變動詞不定式

　　He arrived late so that he missed the train。 / He arrived late so as to miss the train。

　　He wrote so carefully that he made no mistakes。 / He wrote so carefully as to make no mistakes。

　　3、定語從句變動詞不定式（表將來）：

　　This is the meeting which will be held next week。/This is the meeting to be held next week。

　　4、主語從句變動詞不定式（表將來）：

　　It is said that our school will be rebuilt。/Our school to be rebuilt is said。

　　三、從句變動名詞的情況

　　1、主語從句變動名詞

　　It is certain that she will come to the discussion。/Her coming to the discussion is certain。

　　2、表語從句變動名詞

　　My idea is that you should make good use of your time。/Making good use of your time is my idea。

　　3、賓語從句變動名詞

　　I am sure that she will come and join us。/I am sure her coming and joining us。

　　He is pleased that he passed a tough test。/He is pleased his passing a tough test。

　　以上我們不難發現從句轉為非謂語動詞形式要遵循的規律有：

　　1、形容詞性從句（定語從句）提升為動詞分詞和動詞不定式結構時，先行詞要在定語從句中充當主語；

　　2、 狀語從句提升為動詞分詞和動詞不定式結構時，要遵循主從句主語一致的原則；

　　3、 名詞性從句提升為動名詞或動詞不定式時，連接主從句的連接詞that在從句中不充當成分。
