如何能区分省略引导词的宾语从句，定语从句，状语从句？
解题思路：
解题过程：
宾语从句
一、定义：
用作宾语的从句叫宾语从句。宾语从句可以用连词that，连接代词who，whom，what，which；连接副词 how，when，where以及if和whether引起。连接代词和连接副词在宾语从句中作一相应的句子成分，if或whether表示疑问，而that没有意义仅起连接作用。
二、宾语从句的分类：
1． 作动词的宾语从句：
如：Everyone knows that he is a good student.
He wondered how the pyramids were built.
2． 作介词宾语：
如：This depends on how hard you work.
Is there anything wrong in what I said?
3． 作形容词的宾语：
如：They are confident that they can do the job well.
I am not certain whether the train will arrive on time.
三：使用宾语从句要注意的问题：
1． 宾语从句引导词that的省略：
在非正式场合下，that在引导宾语从句时，可以省略。
如：I think (that) you are right.
2． 形式宾语it：
如果宾语从句后面跟有补语，要用形式宾语it来代替，而将从句放到补语的后面去。如：He has made it clear that the meeting will not be postponed.
I heard it said that that factory was founded in 1901.
3．宾语从句的时态呼应：
如果主句的谓语是过去时，宾语从句的时态要按照时态呼应规则进行相应的调整。但是若宾语从句表示的是客观真理或自然观念，其谓语时态仍用一般现在时。
如：He said that he had left his umbrella in the library.
The teacher told the students that the Pacific Ocean is the largest ocean in the world.
4． 宾语从句否定意义的转移：
在think, believe, suppose, expect 等动词所根的宾语中，如果从句谓语是否定的，一般要将否定词not转移至主句谓语上去，而将从句宾语变为肯定形式。
如：I don’t think he has time to play chess with you.
I don’t suppose it is the rush hour yet.
5．一些动词接的宾语从句通常要用虚拟语气：
一般说来，在一些表示坚持(insist)，命令(order，command)，建议(suggest，advise)，要求(require，demand) 等动词之后的宾语从句中，谓语一般要用“should +动词原形”（其中的should在美国英语中常省略，但是引导从句的that通常不省略）：
如：She suggested that we (should) leave early．
He ordered that the medicine (should) be sent by a special plane．
6．whether 与 if
引导介词宾语从句时，只能用 whether，不用if；与“or not”连用时，一般用whether，不用if。
如：I am interested in whether he'll go abroad．
We don't know whether he will come or not．
7．宾语从句的语序
连接词后面为陈述语序。
如：I don’t know what your name is.
8．直接引语变为间接引语
间接引语的使用应注意选择合适的动词。陈述用say／tell，疑问用ask／wonder，而祈使用 tell／order，建议用advise／suggest。注意这些动词后面的结构和语气。
如：“Could you get some tea for me？” Mr．Blake said to his wife．
→Mr. Blake asked his wife whether she could get some tea for him.
“Shall we go dancing tonight？”John said．
→John suggested they should go dancing tonight.
定语从句:
1.定语从句：修饰一个名词或代词的从句称为定语从句，一般紧跟在它所修饰的先行词后面。
2.关系词：引导定语从句的关联词成为关系词
关系词有关系代词和关系副词。关系代词有that, which, who, whom, whose, as等；关系副词有where, when, why等。
关系词常有3个作用：1，引导定语从句。2，代替先行词。3，在定语从句中担当一个成分。
一.关系代词引导的定语从句
1.who指人，在从句中做主语
(1) The boys who are playing football are from Class One.
(2) Yesterday I helped an old man who lost his way.
2. whom指人，在定语从句中充当宾语，常可省略。
(1) Mr. Liu is the person (whom) you talked about on the bus.
(2) Mr. Ling is just the boy whom I want to see.
注意：关系代词whom在口语和非正式语体中常用who代替，可省略。
(3) The man who/whom you met just now is my friend.
3. which指物，在定语从句中做主语或者宾语，做宾语时可省略
(1) Football is a game which is liked by most boys.
(2) This is the pen (which) he bought yesterday.
4. that指人时，相当于who或者whom；指物时，相当于which。在宾语从句中做主语或者宾语，做宾语时可省略。
(5) The number of the people that/who come to visit the city each year rises one million.
(6) Where is the man that/whom I saw this morning?
5. whose通常指人，也可指物，在定语从句中做定语
(1) He has a friend whose father is a doctor.
(2) I once lived in a house whose roof has fallen in.
whose指物时，常用以下结构来代替
(3) The classroom whose door is broken will soon be repaired.
(4) The classroom the door of which is broken will soon be repaired.
(5) Do you like the book whose cover is yellow?
(6) Do you like the book the color of which is yellow?
二.介词+关系代词引导的定语从句
关系代词在定语从句中做介词宾语时，从句常由介词+关系代词引导
(1) The school (that/which) he once studied in is very famous.
(2) The school in which he once studied is very famous.
(3) Tomorrow I will bring here a magazine (that/which) you asked for.
(4) Tomorrow I will bring here a magazine for which you asked.
(5) We’ll go to hear the famous singer (whom/that/who) we have often talked about.
(6) We’ll go to hear the famous singer about whom we have often talked.
注意：1. 含有介词的动词短语一般不拆开使用，如：look for, look after, take care of等
(1) This is the watch which/that I am looking for. (T)
(2) This is the watch for which I am looking. (F)
2. 若介词放在关系代词前，关系代词指人时用whom，不可用who或者that；指物时用which，不能用that；关系代词是所有格时用whose
(1) The man with whom you talked is my friend. (T)
(2) The man who/that you talked with is my friend. (F)
(3) The plane in which we flew to Canada is very comfortable. (T)
(4) The plane in that we flew in to Canada is very comfortable. (F)
3. “介词+关系代词”前可有some, any, none, both, all, neither, most, each, few等代词或者数词
(1) He loved his parents deeply, both of whom are very kind to him.
(2) In the basket there are quite many apples, some of which have gone bad.
(3) There are forty students in our class in all, most of whom are from big cities.
三．关系副词引导的定语从句
1. when指时间，在定语从句中做时间状语
(1) I still remember the day when I first came to the school.
(2) The time when we got together finally came.
2. where指地点，在定语从句中做地点状语
(1) Shanghai is the city where I was born.
(2) The house where I lived ten years ago has been pulled down.
3. why指原因，在定语从句中做原因状语
(1) Please tell me the reason why you missed the plane.
(2) I don’t know the reason why he looks unhappy today.
注意：关系副词引导的从句可以由“介词+关系代词”引导的从句替换
(1) The reason why/ for which he refused the invitation is not clear,
(2) From the year when/in which he was going to school he began to know what he wanted when he grew up.
(3) Great changes have taken place in the city in which./where I was born.
