刘老师，所有的定语从句都能进行简化变成非谓语动词结构吗？比如说在下面这个句子：

I can't agree more with the suggestions you have put forward.

像这样主句和从句的主语不一致，从句还能被简化成现在分词吗？对于从句的简化一直很迷惑，希望老师可以用例句详细解释一下，谢谢！

回答如下：

非谓语动词与从句之间相互转化是英语中非常重要语言现象。(以上也是英语学习者，特别是英语初学者比较难掌握的英语语法现象。）

根据非谓语动词也可做定语这一特点，为了句子达到更加精练和简洁的效果，可以使用用非谓语替代定语从句在句中作后置定语. （其前提条件是关系代词在从句中充当主语成分， 方法就是去掉"关系代词和助动词be动）。

定语从句简化为“非谓语动词结构”的形式可以归纳为以下几种

(1)定语从句简化为现在分词或现在分词短语作前置或后置定语。 

 The man who is standing under the tree is our English teacher. 

 →The man standing under the tree is our English teacher.   

站在树下面的那个人是我们的英语老师。 

(2)定语从句简化为过去分词短语作后置定语。 

 She is the girl who was praised at the school meeting. 

 →She is the girl praised at the school meeting.   

她就是在校会上受表彰的那个女孩。 

(3)定语从句简化为不定式作后置定语。 

 He is always the first person that comes to school. 

 →He is always the first person to come to school. 

 他总是第一个到校。

I have many letters which I should type． 

→I have many letters to type．(动宾关系.自己打印)

I have many letters which I should type．

→I have many letters to be typed．(被动主谓关系；别人打印)

→I have many letters which are to be typed by other．

下面是关于非谓语动词作状语与状语从句之间相互转化只是拓展讲解,希望对你也有帮助。

非谓语动词与从句间的相互关系及转换:，它们之间可以有条件的进行相互转换。　　

一、非谓语动词与从句的相互关系

(二)不定式和分词作状语相当于状语从句

(1)不定式多作目的状语和结果状语．故可以转化为相应的目的状语从句和结果状语从句。

Mother got up early to catch the early bus．

(目的状语）

→Mother got early so as to(in order to)catch the early bus．

→Mother got up early so that(in order that)she migllt catchthe early bus．

【特别注意】so as to和so that不可放在句首。

She is too young to join the army．(结果状语)

She is so young that she cannot join the army．

(2)分词作状语可以表示时间、原因、条件、方式和让步等，相当于相应状语的从句。如果分词的逻辑主语与主句主语一致，则用现在分词；如果分词的逻辑主语与主句是被动关系且主语一致时，则用过去分词。分词作状语时，如果其带有逻辑上的主语，称为分词的独立主格结构。分词的逻辑主语与句子的主语无语法联系。

Seeing those pictures．he couldn't help thinking of the unforgettable days in New York．(时间状语)

→When he saw those pictures．he couldn"t help thinking of the unforgettable days in New Y0rk．

二、非谓语动词与从句的相互转换

(一)不定式与从句之间的转换

(1)不定式作主语可转换成主语从句。

When and where for we to hold the meeting is unknown yet．

→When and where We'will hold the meeting is unknown yet．

(2)不定式作宾语或宾补可转换成宾语从句。

I don't know what to do with the matter．

→I don't know what I should do with the matter．

(3)不定式作表语可转换成表语从句。

My wish is to become a pilot after graduation．

→My wish is that I can become a pilot after graduation．

(4)不定式作定语可转换成定语从旬。

The meeting to be held tomorrow is ofgreat importance．

→The meeting that／which will be held is ofgreat importance．

(5)不定式作目的、结果、原因状语可转换成相应的状语从句。

They Started off early in order to(so as to)arrive in time．

They started off early in order that(so that)they could arrive in time．

(二)动名词与从句之间的转换

(1)动名词作主语可转换成that引导的主语从句。

Tom’s knowing English helps him in learning French．

→That Tom knows English helps him in learning French．

(2)动名词作宾语可转换成that引导的宾语从句。

I remember having paid him for his work．

I remember that I have paid him for his work．

(3)动名词作表语可转换成that引导的表语从句。

Our worry is your depending too much on him．

→Our worry is that you depend too much on him．

(三) 分词与从句之间的转换

(1)分词作定语可转换成that，who，which引导的定语从句。

The man talking to my teacher is my father．

→The man who／that is talking to my teacher is my father．

分词作状语可转换成相应的状语从句。

While waiting for the bus,I caught sight ofher．

→while I was waiting for the bus．I caught sight ofher．

分词作宾补可转换成宾语从句。

I found him waiting for a bus at the station．

→I found that he was waiting for a bus at the station．

分词在句中作伴随或结果状语时。相当于一个并列句。也可和 tII结构转换。

He died,leaving his daughter much money．

→He died and he left his daughter much money．

三,分词的独立主格结构与从句的相互转换

(一)独立主格结构转换为从句

(1)表示时间的独立主格结构可转换为时间状语从旬。

The shower being over，we continued our joumey．

→When the shower was over．we continued our journey．

(2)表示理由的独立主格结构可转换为原因状语从句。

Au the tickets having been sold out，they went away disappointed ．

→As all the tickets had been sold out，they went away disanppointed ．

(3)表示条件的独立主格结构可转换为条件状语从句。

All things considered，her paper is better than yours.

→If all things are considered．her paper is better than yours.

(4)表示伴随状态的独立主格结构可转换为并列句或两个独立的句子。

He went to the front door．his students following him．(=He went to the front door，followed by his students．)

→He went to the front door．and his students followed him．

(二)从句转换为分词的独立主格结构

(1)从句变为分词的独立主格结构时，要去掉连词，保留自己的主语。然后把从句的谓语变换为分词结构。试比较下面的句子。

Mother being ill in bed．I can't go to scho1．

→As Mother is iu in bed．I can 't go to schoo1．

(2)表示伴随状态的独立主格结构有时可在其前面加用tll或without．

He went away，and not awordwas spoken．

→He went away．without a word spoken．

你说的是将从句简化为非谓语动词的形式吧，对于例句从句是定语从句，而连接词是充当从句的主语，从句的主语与主句的主语不同，因此无法简化为非谓语动词，这是我的理解。期盼刘老师解答！
