英语语法经典例题800例：非谓语动词（例题1）
【导语】英语语法让很多学生都头疼，因为复杂难懂的句式和词组有时难以记忆。为大家整理了英语语法大全，希望对同学们的英语语法学习有所帮助。更多内容尽在。
1. Everyone in our class was working hard and doing what we could _______ a good college.
A. enter B. to enter
C. entering D. entered
【陷阱】容易误选A。有的同学一看到空格前的情态动词 could 就断定此处应填动词原形 enter。
【分析】其实正确答案应是B。此句为省略句，即在 could 后省略了动词 do，若把句子补完整应为Everyone in our class was working hard and doing what we could do to enter a good college。即句中的不定式短语(to enter a good college)是用作目的状语的，而不是与情态动词(could)一起构成谓语。请再看类似例句：
(1) They did what they could to comfort her. 他们尽量安慰她。
(2) They did everything they could to save her life. 他们尽一切力量拯救她的性命。
(3) He studies as hard as he could to catch up with his classmates. 他拼命学习以便赶上他的同学。
值得指出的是，这也并不是说今后只要遇到类似结构的题就一定选带to不定式。请看以下试题：
(4) He ran as fast as he could _____ to catch the early bus.
A. to hope B. hope
C. hoping D. hoped
此题的答案是 C不是A，其中的现在分词短语 hoping to catch the early bus 用作伴随状语。
(5) He spent every minute he could _____ spoken English.
A. practise B. to practise
C. practising D. practised
此题答案选 C，这与前面动词 spent 的搭配有关，即 spend … (in) doing sth。若将此句补充完整，即为 He spent every minute he could spend in practising spoken English.
(6) Before going abroad he devoted all he could ____D____ his oral English.
A. improve B. to improve
C. improving D. to improving
此题答案选D，注意两点：一是 devote … to … 是固定搭配，意为“把……贡献给……”;二是其中的 to 是介词，不是不定式符号，后接动词时要用动名词。
2. He knows nothing about it, so he can’t help _______ any of your work.
A. doing B. to do
C. being doing D. to be done
【陷阱】容易误选B，根据 can’t help doing sth 这一结构推出。
【分析】其实答案应选A。比较以下结构：
can’t help to do sth = 不能帮助做某事
can’t help doing sth = 禁不住做某事，情不自禁地做某事
又如下面一题，答案也是 B：
She can’t help ____ the house because she’s busy making a cake.
A cleaning B. to clean
C. cleaned D. being cleaned
再请看以下试题：
While shopping, people sometimes can’t help _____ into buying something they don’t really need.
A. to persuade B. persuading
C. being persuaded D. be persuaded
此题应选C，句中的 can’t help 意为“禁不住”(注意根据句意用被动形式)。
3. All her time _______ experiments, she has no time for films.
A. devoted to do B. devoted to doing
C. devoting to doing D. is devoted to doing
【陷阱】几个干扰项均有可能误选。
【分析】此题最佳答案为B。现分析如下：
(1) devote 意为“致力于，献身于”，主要用 devote…to…或be devoted to，其中的to 是介词，不是不定式符号，故后接动词时要用动名词，不用不定式。
(2) 选A错误：若将 do 改为 doing 则可以。
(3) 选B正确：all her time devoted to doing experiments为独立主格结构，用作状语。
(4) 选C错误：因为all her time 与 devote 为被动关系，故应将devoting改为devoted。
(5) 选D错误：若单独看 All her time is devoted to doing experiments，此句并没有错，但问题是逗号前后两个简单句没有必要的连接方式，所以从整体上看仍不对，假若在后一句的'句首加上and或so，则可选D，或将D将中的is 改为 being也可选它。
英语语法经典例题800例：虚拟语气（例题）
【导语】英语语法让很多学生都头疼，因为复杂难懂的句式和词组有时难以记忆。为大家整理了英语语法大全，希望对同学们的英语语法学习有所帮助。更多内容尽在。
1. I forget where I read the article, or I _____ it to you now.
A. will show B. would show
C. am going to show D. am showing
【陷阱】几个干扰项均有可能误选。
【分析】正确答案选B。根据上文的语境可知句中的 or 隐含有一个虚拟的条件，即 or=if I didn’t forget where I read the article(要是我没忘记我在哪儿读过这篇文章的话——但事实上忘了)。
2. “It looks as if he were drunk.” “So it does. _____.”
A. He’d better give up drinking
B. He shouldn’t have drunk so much
C. Health is more important than drink
D. I wonder why he is always doing so
【陷阱】几个干扰项均有可能误选，主要是受句中 drunk 一词的影响。
【分析】最佳答案为D。关键信息是It looks as if he were drunk 中的虚拟语气，句子既然用了虚拟语气，也就是说，“他喝醉了”不是事实，只是他的言行好像是醉了，所以此题的最佳答案是D。
3. “Mary looks hot and dry” “So _____ you if you had so high a fever.”
A. do B. are
C. will D. would
【陷阱】容易误选A或C。选A者，认为前后两句的动词性质应一致;选C者，认为其后带有if 条件状语从句，从语气上看，主句应用将来时态。
【分析】此题最佳答案为D。分析如下：
(1) “so + 助动词 + 主语”是一个很有用的结构，它表示“……也一样”时。如：
He likes to watch TV, and so do I. 他喜欢看电视，我也一样。
When animals and plants disappear, so will man. 当动植物消失的时候，人类也会随之消失。
(2) 由于空格后的 if 条件状语从句的谓语用的是虚拟语气(这是很重要的信息)，所以主句要用 would 而不用 will，即答案应选D。
英语语法经典例题800例：强调句（例题）
【导语】英语语法让很多学生都头疼，因为复杂难懂的句式和词组有时难以记忆。为大家整理了英语语法大全，希望对同学们的英语语法学习有所帮助。更多内容尽在。
1. ____ that caused him to serve dinner an hour later than usual.
A. It was we being late B. It was our being late
C. It was we were too late D. It was because we were late
【陷阱】此题容易误选D，认为强调的是原因状语从句 because we were late。
【分析】但实际上，此题的答案为B，强调的是句子主语 our being late，此题若还原成非强调句，即为：
Our being late caused him to serve dinner an hour later than usual.
注意，强调句的一个显著特点是，若去掉强调结构 it is [was]… that…，句子仍然成立;换句话说，该结构中的 that 不能充当句子成分。
2. “How was ______ they discovered the entrance to the underground palace?” “Totally by chance.”
A. it that B. he that
C. it when D. he which
【陷阱】几个干扰项均可能误选。
【分析】答案选A，为强调句的特殊疑问句形式，其相应的陈述句形式为：
It was totally by chance that they discovered the entrance to the underground palace.
比较以下各题，它们也属强调句的特殊疑问句形式：
(1) Who was it _____ saved the drowning girl?
A. since B. as C. that D. he
答案选C，被强调成分为 who，该句实为类似 It was Tom that saved the drowning girl. 这类强调句的特殊疑问句形式(即对其中的Tom 提问而得)。
(2) What is it _____ his daughter needs most?
A. what B. which C. that D. if
答案选C，被强调成分为 what，该句实为类似 It is a bike that his daughter needs most. 这类强调句的特殊疑问句形式(即对其中的a bike 提问而得)。
3. _____ was very ______ that little Jim wrote the letter.
A. It, careful B. It, carefully
C. He, careful D. He, carefully
【陷阱】几个干扰项均有可能误选，但最有可能误选的可能是A，认为这是一个普通的系表结构，即认为第二空要填形容词作表语。
【分析】其实，此题是一个强调句，其非强调形式为 Little Jim wrote the letter very carefully. 若用 it is … that… 的强调句式强调其中的状语 very carefully 即为上面一题的题干，所以答案应选B。请看下面几例，也属强调结构：
(1) It was when she was about to go to bed ______ the telephone rang.
A. since B. as C. that D. then
答案选C，被强调成分为 when she was about to go to bed 这一时间状语从句。
(2) It may have been at Christmas _____ John gave Mary a handbag.
A. before B. who C. that D. when
答案选C，被强调成分为 at Christmas，其中的动词 be 采用了 may have been 这一较为复杂的形式。
4. “Where did you find the professor who made the speech yesterday?” “It was in the hall ______ the students
often have a meeting.”
A. where B. which
C. that D. when
【陷阱】很可能误选C，认为这是一个强调句，强调地点状语 in the hall。
【分析】假若选C，即有 It was in the hall that the students often have a meeting，该句的意思是“学生们通常是在
大厅开会”，单独看这一句，无论是其意思还是其语法均未错，但若将其与上文联系起来看，则不通，因为上文的意思是“你是在
哪儿找到昨天作报告的那位教授的?”假若将答句改为 It was in the hall that I found the professor，则完全可以。
其实，此题的最佳答案是A，where the students often have a meeting 为定语从句，用以修饰其前的名词 the hall，句意
为“是在学生们经常开会的那个大厅(找到教授的)”，这样语意就通顺了。
5. It was what he meant rather than what he said ______ annoyed me.
A. which B. as
C. what D. that
【陷阱】几个干扰项均有可能误选。
【分析】此题为一个强调句型，空格处应填 that (即选D)，被强调成分为 what he meant rather than what he said。句意
为“让我生气的不是他说的话，而是他话中的意思”。请再看两例：
(1) It was his nervousness in the interview ______ probably lost him the job.
A. which B. since C. that D. what
答案选C，为强调句型，被强调成分为 his nervousness in the interview，句意为“很可能是面试时表现出紧张，使他失去
了这份工作”。
(2) It is the ability to do the job ______ matters not where you come from or what you are.
A. one B. that C. what D. it
答案选B，为强调句型，被强调成分为 the ability to do the job，句意为“重要的是你做工作的能力，而不是你来自何地
或你是从事什么工作的”。

◆典型陷阱题分析◆
1. She was so angry and spoke so fast that none of us understood _______ he said meant.
A. that B. what
C. that that D. what what
【陷阱】可能误选B。许多同学一看选项首先就排除了C和D，认为这样两个“引导词”叠用的情况不太可能。在A和B两个选项中，选项A肯定不行，因为它引导宾语从句时不能充当句子成分，所以便选择了B。
【分析】正确答案选 D。第一个what 用作动词 meant 的宾语，第二个what 用作动词 said 的宾语，即在 none of us understood what what he said meant 中，none of us understood 为主句，what what he said meant 为宾语从句，而在此宾语从句中又包括有 what he said 这样一个主语从句。
2. After _______ had happened he could not continue to work there.
A. which B. how
C. what D. having
【陷阱】可能误选A。
【分析】最佳答案选 C。有的同学误选A，是因为认为介词后应接关系代词 which，但实际上，若填关系代词，其前没有先行词，这根据不是一个定语从句。另外，由于 had happened 缺主语，所以B和D也不能选。请再做下面一题(答案选B)：
He pointed to ______ looked like a tomb and said, “Ghost.”
A. that B. what
C. which D. as
3.“Is ______ you want to say?” asked the teacher.
A. this B. that
C. all that D. that all
【陷阱】根据中文字面意思误选A或B。
【分析】最佳答案选 D。假若选A或B，那么转换成陈述句即为：This is you want to say. / That is you want to say. 显然句中的两个谓语动词 is与want相冲突。选D组成的句子是 Is that all you want to say? 其中的that 为句子主语，all 为表语，you want to say 为定语从句，用以修饰all。
4. “When ______ leave for Japan?” “When ______ leave for Japan is kept secret.”
A. they will, will they B. will they, they will
C. they will, they will D. will they, will they
【陷阱】可能误选D，认为 when 后应用疑问句词序。
【分析】最佳答案选 B。第一个when引出的是一个特殊疑问句，故用疑问词序;第二个 when 引出的是主语从句，故其后用陈述句词序。请做以下试题(答案选C)：
(1) None knows if _______ that boy, but if _______ him, her parents will be disappointed.
A. she will marry, she will marry B. she marries, she marries
C. she will marry, she marries D. she marries, she will marry
(2) “Where _______ go to work?” “Where _______ go to work is not known.”
A. we shall, we shall B. shall we, shall we
C. shall we, we shall D. we shall, shall we
5. Someone is ringing the doorbell. Go and see ______.
A. who is he B. who he is
C. who is it D. who it is
【陷阱】几个干扰项均有可能误选。
【分析】此题最佳答案为D。首先可以排除A和C，因为空格处实为一个宾语从句，所以不能用疑问句词序。另一方面，但按英语习惯，当用于指代身份不明的人时，要用代词it，而不用 he 或she等。比较以下两句：
Mr Smith is at the door. He wants to see you. 史密斯先生在门口，他想见你。
Someone is at the door. It may be the postman. 有个人在门口，可能是邮递员。
第一句因前面指明了是 Mr Smith，所以后面用代词 he;而第二句因前面用的是不定代词 someone，说明此人身份尚不明确，故其后用了代词 it 来指代。
6. Don’t you know, my dear friend, ______ it is your money not you that she loves?
A. who B. which
C. that D. what
【陷阱】此题容易误选 A或B：选 A 的同学认为这是指人的，故用who;选B的同学认为这是非限制性定语从句，两者都是误认为这是定语从句(注意没有先行词)。
【分析】其实答案应选C。that引导的是一个宾语从句，用作动词 know 的宾语，它只是被句中的插入语 my dear friend 隔开罢了。请做以下试题(答案均为C)：
(1) Everyone knows, perhaps except you, _______ your girl-friend is a cheat.
A. who B. which
C. that D. what
(2) I think, though I could be mistaken, ______ she liked me.
A. who B. which
C. that D. what
(3) He told me the news, believe it or not, ______ he had earned $1 000 in a single day.
A. that B. which
C. as D. because
前面两题 that 引导宾语从句，后面一题 that同位语从句(修饰the news)。
英语语法大全：特殊同位语归纳
英语语法让很多学生都头疼，因为复杂难懂的句式和词组有时难以记忆。为大家整理了英语语法大全，本章主要介绍英语语法中的句子成分，希望对同学们的英语语法学习有所帮助。更多内容尽在。
特殊同位语归纳
当两个词或词组在一个句子中具有相同的语法地位而且描述相同的人或事物时，我们称它们为同位语。基本形式的同位语大家一般不会出错，但有几种同位语，或由于本身结构特殊，或由于它修饰的成分结构比较特殊，往往会引起误解。现小结并举例说明如下，希望引起同学们的注意。
1. 代词we, us, you等后接同位语
Are you two reading? 你们二人在看书吗?
They three joined the school team. 他们3人参加了校队。
She has great concern for us students. 她对我们学生很关心。
He asked you boys to be quiet. 他要你们男孩子安静些。
We girls often go to the movies together. 我们女孩子经常一起去看电影。
2. 不定式用作同位语
Soon came the order to start the general attack. 很快下达了发起总攻的命令。(to start the general attack与the order同位)
He followed the instruction to walk along a certain street where I picked him up. 他照吩咐沿某一条街走，我在那里接他上了车。(to walk along…与the instruction同位)
3. -ing分词用作同位语
He's getting a job tonight driving a truck. 他今晚得到一个开卡车的差事。(driving a track与a job同位)
She got a place in a laundry ironing shirts. 她在一家洗衣店得到一个熨衣服的职位。(ironing shirts与a place同位)
The first plan, attacking at night, was turned down. 第一个计划是夜袭，被拒绝了。(attacking at night与the first plan同位)
4. 形容词用作同位语
The current affair, the biggest in its history, is being held in Guangzhou. 目前的交易会，是有史以来规模最大的，正在广州举行。
He read all kinds of books, ancient and modern, Chinese and foreign. 他读了很多书，古今中外都有。
People, old and young, took to the streets to watch the parade. 老老少少的人都来到街头观看游行。
【注】这类同位语与定语比较接近，可转换成定语从句。如：
The current affair, the biggest in its history, is being held in Guangzhou.
=The current affair, which is the biggest in its history, is being held in Guangzhou.
5. none of us之类的结构用作同位语
We none of us said anything. 我们谁也没说话。
We have none of us large appetites. 我们谁饭量都不大。
They neither of them wanted to go. 他们两人都不想去。
They've neither of them succeeded in winning her confidence. 他们两人谁也没能赢得她的信任。
【注】同位语并不影响其后句子谓语的“数”，如：
学生每人都有一本词典。
正：The students each have a dictionary.
误：The students each has a dictionary.
请比较下面一句(谓语用了单数，因为each为句子主语)：
正：Each of the students has a dictionary.
6. 从句用作同位语(即同位语从句)
They were worried over the fact that you were sick. 他们为你生病发愁。
I received a message that she would be late. 我得到的信息说她可能晚到。
The news that we are having a holiday tomorrow is not true. 明天放假的消息不实。
The idea that you can do this work without thinking is wrong. 你可以不动脑筋做此工作的想法是错误的。
宾语从句意义
语法是语言的组织规律，任何人在使用语言时，不管他是否学过语法，都须合乎语法。另外，总结语法本身的规律也能加深我们对语言的理解，让我们能够真正熟练地运用语言。（宾语：指一个动作（动词）的接受者，常置于动词之后，也有双宾语结构例句：he gave me a book，类似拥有me和book两个宾语的句子叫双宾语从句），在复合句中，由一个句子充当宾语，这个句子就叫做宾语从句。
宾语从句定义
置于动词、介词等词性后面起宾语作用的从句叫宾语从句。宾语从句的语序必须是陈述语序。谓语动词、介词、动词不定式，v.-ing形式后面都能带宾语从句。有些形容词（afraid,sure,glad等）之后也可以带宾语从句。
宾语从句特点
宾语从句可以作及物动词、介词及形容词的宾语。
宾语从句的语序一律用陈述句语序。
连接词that引导宾语从句在句中无词义，不充当句子成分，多数情况下可以省略。
whether 和 if 都可引导宾语从句，但 whether后可紧跟or not；whether从句可作介词的宾语。
如果从句太长，可以用形式宾语it. 补充宾语从句在句子中起宾语作用的从句叫做宾语从句.宾语从句分为三类:
（1）动词的宾语从句,介词的宾语从句和形容词的宾语从句.时态：1·主句用一般现在时，从句可用任意时。 2·主句用过去时，从句用过去某个时态。 3·主句用过去时，从句是真理时，只用一般现在时。
（2）宾语从句的从属连词主要有that,if,whether.that引导表示陈述句的宾语从句,而if和whether引导表示“是否”的宾语从句.
He told that he would go to the college the next year他告诉我他下一年上大学.
I don’t know if there will be a bus any more.我不知道是否还会有公交车.
Nobody knew whether he could pass the exam.没人知道他是否会通过考试.
连接代词连接代词主要有who, whom ,whose ,what ,whoever ,whomever ,whosever, whatever, whichever等.连接代词一般指疑问,但what, whatever除了指疑问外,也可以指陈述.

I don’t know whom you should depend on.我不知道你该依靠谁.
The book will show you what the best CEOs know.这本书会告诉你最好的执行总裁该了解些什么.

连接副词连接副词主要有when,where,why,how,whenever,wherever,however等.
He didn’t tell me when we should meet again.他没有告诉我什么时候我们能再见面.
Could you please tell me how you read the new panel?你能展示给我怎么用这个新的操作盘吗?
None of us knows where these new parts can be bought.没有人知道这些的新的零件能在哪里买到.
（3）动词的宾语从句大多数动词都可以带宾语从句
We all expect that they will win , for members of their team are stronger.我们都预料他们会赢,因为他们的队员更强壮.
He told us that they would help us though the whole work.他告诉我们在整个工作中,他都会帮忙的.
部分“动词+副词”结构也可以带宾语从句
I have found out that all the tickets for the concert have been sold out.我发现这场音乐会的所有票都卖光了.
Can you work out how much we will spend during the trip?你能计算出这次旅行我们将花费多少钱吗?
动词短语也可以带宾语从句常见的这些词有:make sure确保 make up one’s mind下决心 keep in mind牢记
Make sure that there are no mistakes in your papers before you turn them in.在上交试卷前确保没有任何错误.
可运用形式宾语it代替的宾语从句
①动词find,feel,consider,make,believe等后面有宾语补足语的时候,则需要用it做形式宾语而将that宾语从句后置.
I think it necessary that we take plenty of hot water every day .我认为每天多喝开水是有必要的.
I feel it a pity that I haven’t been to the get-together.我没去聚会,感觉非常遗憾.
I have made it a rule that I keep diaries. 我每天写
We all find it important that we (should) make a quick decision about this mater. 我们都认为对这件事马上做出决定很重要.
②有些动词带宾语从句时寻要在宾语与从句前加it这类动词主要有:hate, take , owe, have, see to.
I hate it when they talk with their mouths full of food.我讨厌他们满嘴食物时说话.
He will have it that our plan is really practical.他会认为我们的计划确实可行.
We take it that you will agree with us.我们认为你会同意我们的.

③若宾语从句是wh-类,则不可用it代替
We all consider what you said to be unbelievable.我们都认为你所说的是不可信的.

3.介词的宾语从句用wh-类的介词宾语从句

用that,if引导的介词宾语从句有时候except,but,besides三个介词后可见到that引导的宾语从句
I know nothing about my new neighbor except that he used to work with a company.对于我的新邻居我只知道他曾在一家公司上班,其他一无所知.
4.形容词的宾语从句常用来引导宾语从句的形容词有: sure,certain,glad,please,happy,sorry,afraid,satisfied,surprisedI am sure
I will pass the exam.我确信我会通过考试.
I am sorry that I have troubled you so long.很抱歉我这么长时间在打扰你.
He is glad that Li Ming went to see him when he was ill.他很高兴在他生病的时候李明能去看望他.
5.if,whether在宾语从句中的区别
①if和whether在作“是否”解时,引导宾语从句常放在动词know,ask,care,wonder,find out等之后,介词后一般不用if
②少数动词,如:leave,put,discuss,doubt后的宾语从句常用whether.
③whether后可以加or not,但是if不可以.
④在不定式前只能用whether.如： I can’t decide whether to stay. 我不能决定是否留下。
⑤避免歧异时,我们常用whether而不用if.
6.哪些宾语从句不可以省略引导词that当that作learn,suggest,explain,agree,wonder,prove,mean,state,feel,hold等动词的宾语时;当宾语从句较长时;当主语状语置于主句尾,宾语从句之前时;当主语谓语动词(包括非谓语动词)与宾语从句之间有插入语时;当一个动词带有两个或两个以上宾语从句时,此时第一个that可以省略,第二个that不可以省略;当宾语从句中的'主语是this,that或this,that做主语的定语时;当宾语从句是双宾语中的直接宾语时;当宾语从句的主语是非谓语动词或主语从句时;当主语中的谓语动词是固定词组时;当宾语从句有it做其先行词时;在直接引语中,转述分句把宾语从句隔开时
宾语从句的否定转移主句的谓语动词是think,believe,imagine,suppose,consider,espect,fancy,guess等,并且主句的主语是第一人称而且为一般现在时,从句的否定词一般要转移到主句上来,其反义疑问句一般与宾语从句一致.
I don’t think he will come to my party.而不能说成I think he won’t come to my party.我认为他不会来我的舞会.
I don’t believe that man is killed by Jim,is he?我认为那个人不是Jim所杀的,是不是?如果宾语从句中有某个含有否定意义的形容词或副词,其反义疑问句要用肯定形式.
We find that he never listens to the teacher carefully,does he?我们发现他从来不仔细听老师讲课,是不是?
宾语从句的时态和语序当主句为现在时或将来时的时候,宾语从句的时态一般不受主句的时态所影响.当主句为过去时的时候
①从句用一般过去时或过去进行时表示与主句谓语动词动作同时发生
I only knew he was studying in a western country,but I didn’t know what country he was in.我只知道他当时在西方的一个国家读书,可不知道是哪个国家.
He asked me if I was reading the story The Old Man and the Sea when he was in.他问我他进来的时候我是否正在读<老人与海>.
②从句过去完成时表示该动作发生在主句谓语动作之前
He told me that he had told Mary about the meeting already.他告诉我他已经把有关会议的事情告诉的了Mary.
③从句谓语用过去将来时表示该动作发生在主句谓语动作之后
The reporter asked if the government would take necessary measures to put down the to-do.记者问政府是否会采取必要的措施镇压骚乱.
如果从句是一个客观真理,那么从句的时候不根据主句的时态而变化
The teacher said that the moon goes around the earth yesterday.老师昨天说月亮绕着地球转.
当宾语从句的引导词是who,which,what,when,where,how,why等表疑问时,不能按正常语序安排,经常将这类引导词置于句首
Who do you think the public might choose as their favorite singer this year?你认为今年公众会选谁为他们最喜欢的歌手
宾语从句，即：在主句中担当宾语的从句。学习宾语从句要抓住三要素：连接词、语序和时态。 连接词一般都是that(指事务或人),which（指事）,who（指人）
1．从句为陈述句，常选择连接词that或将that省略，直接与主句相连。
2．从句为一般疑问句，常选择连接词if或whether。在whether…ornot结构中不能用if替换。
3．从句为特殊疑问句，常选择what,when,where,which,who,how等的疑问代、副词作连接词。
注意：当who为主语时，句式为：who+谓语+其他三：判断时态情况：
1。主句是一般现在时，从句为各种时态情况
2。主句是一般过去时，从句为各种相应过去时态注意：从句描绘客观事实，用一般现在时
1. The teacher told the children that the sun____ round. 【A. was B. is C. were D. are】
2. I believe that our team____ the basketball match.【 A. win B. won C. will win D. wins 】
3. I don’t know____ to visit the old man. 【A. whether B. if C. that D. who】 The soldiers soon reached( )was once an old temple( )the villagers used as a school. 【A.which;where B.what;which C.where;which D.what;where】
答：选B，动词reach后接宾语从句，从句缺少宾语，where不可，which引导宾语从句时表疑问含义“哪一个…”而此句中并非疑问含义，不知道哪一座庙宇，而是用what从句表陈述含义，意“过去的一座旧庙宇”；temple后为对其修饰的定语从句，用关系代词which代替，并在从句中作动词used的宾语，use sth. as…“把…用作…whether + or not 宾语从句，在复合句中作宾语，位于及物动词后；
eg． Tell him which class you are in ． Do you know what he likes？
注：(1)主、从句时态一致： 主句谓语过去时，从句相应过去时； He answered that he was listening to me. 主句谓语现在时，从句时态任所需；
eg． He says (that) he will leave a message on my desk. They know (that) he is working hard. 具体过去永不变，真理格言现在时；
eg． He told me that he was born in 1980. Father told me that practice makes perfect .
（2）否定前移，及完成反意问句； 在think / believe / suppose / guess / imagine / expect等动词后跟宾语从句否定式时，应转移到主句上去，完成反意问句时，应与从句主、谓保持一致。（注: 否定前移的条件是，主句主语是第一人称）
eg． I don't think you are right ,are you ? I don't believe they have finished their work yet,have they ?
（3）在表示建议 suggest , advise 要求demand 、desire、require、request、propose； 决定 decide; 命令 order、command; 坚决主张 insist; 等动词后跟宾语从句，用（should）+v．（虚拟语气）
eg． I suggested that you（should）study hard． He ordered that we should go out at once．
（4）如果宾语从句后有宾语补语，用it作形式宾语，把宾语从句后置
eg．You may think it strange that he would live there．
（5）宾语从句that常可省略，但在以下情况下不能省略
A．当主句谓语动词带有两个或两个以上宾语从句时，可以省略第一个that，其他不能省略。
eg．I believe（that）you have done your best and that things will get bet?．
B．当it作形式宾语时
eg．She made it clear that she had nothing to do with him．
C．当宾语从句前置时
eg．That our team will win，I believe．
宾语从句时态
主句是一般现在时，从句根据实际情况使用任何时态。
例句：The headmaster hopes everything goes well.
主句是一般过去时，从句须用过去时态的某种形式。
例句：She was sorry that she hadn’t finished her work on time.
当宾语从句表示的是一个客观真理或者事实真理时，即使主句是过去时，从句也用一般现在时态。
例句：The teacher told his class that light travels faster than sound.[2]
宾语从句语序
宾语从句的语序是陈述句语序即：连接代词/副词+主语+谓语+其他成分。即：连接代词/副词+陈述句语序。例句如下：
I don’t know what they are looking for.
Could you tell me when the train will leave?
Can you imagine what kind of man he is?
用法
宾语从句
宾语从句的连接词：that
结构：主语+谓语+宾语（陈述语序）
注意：
引导词为that ；
语序为v.+主语+谓语+由if、whether引导宾语从句；
主句为现在时 从句为任意时态。
从属连词
连接宾语从句的从属连词主要有that,if,whether，和疑问词（what， how， where， when ...)。
that引导表示陈述句的宾语从句，
if和whether，whether...or not引导表示“是否”的一般疑问句的宾语从句。
关联代词
连接代词主要有who,whom,whose,what,whoever,whomever,whosever,whatever,whichever等。
连接代词一般指疑问，但what,whatever除了指疑问外，也可以指陈述。
关联副词
连接副词主要有when,where,why,how,whenever,wherever,however等。
例句：
He didn’t tell me when we should meet again.
他没有告诉我什么时候我们能再见面。
注：宾语从句通常跟在名词或代词后面。
动宾从句
大多数及物动词都可以带宾语从句。
部分“动词+副词”结构也可以带宾语从句。
动词短语也可以带宾语从句，常见的这些词有：
make sure（确保）、make up one’s mind（下决心）、keep in mind（牢记）
可运用形式宾语it代替的宾语从句
①动词find,feel,consider,make,believe,think等后面有宾语补足语的时候，则需要用it做形式宾语而将that宾语从句后置。
②有些动词带宾语从句时需要在宾语从句前加it（双宾语）这类动词主要有：hate,take,owe,have,see to.award,lend.hand,mail,offer,pass,pay,post,read,return,show,teach,tell
介宾从句
用whether之类的介词宾语从句。
用that,if引导的介词宾语从句，有时候except,but,besides三个介词后可见到that引导的宾语从句。
形容+宾从句
有些形容词具有动词的含义，所以也可以带一个宾语从句；
例句：
I am sorry I am late.
I am glad that you can join us.
Are you sure his answer is right?
常用来引导宾语从句的形容词有：sure,certain,glad,pleased,happy,sorry,afraid,satisfied,surprised
if与whether
if和whether在作“是否”理解时，引导宾语从句常放在动词know,ask,care,wonder,find out等之后，介词后一般不用if。
少数动词，如：leave,put,discuss,doubt后的宾语从句常用whether。
whether后可以加or not,但是if不可以。
在不定式前只能用whether。
一般“no matter”后表示“是否”用whether而不用if。
不省略引导词
存在以下情况时引导词that不可省略：
that作learn,suggest,explain,agree,wonder,prove,mean,state,feel,hold等动词的宾语。
宾语从句较长。
主语状语置于主句尾，宾语从句之前。
主语谓语动词（包括非谓语动词）与宾语从句之间有插入语。
一个动词带有两个或两个以上宾语从句时，第一个that可以省略，第二个that不可以省略。
宾语从句中的主语是this,that或those,these做主语的定语。
宾语从句是双宾语中的直接宾语。
宾语从句的主语是非谓语动词或主语从句。
主语中的谓语动词是固定词组。
宾语从句有it做其先行词。
直接引语中，转述分句把宾语从句隔开。
that在从句中充当主语。
否定转移
主句的谓语动词是think,believe,imagine,suppose,consider,expect,fancy,guess等，并且主句的主语是第一人称而且为一般现在时，从句的否定词一般要转移到主句上来，其反义疑问句一般与宾语从句一致.
如果宾语从句中有某个含有否定意义的形容词或副词，其反义疑问句要用肯定形式.我们通常称为否定前移。
时态和语序
当主句为现在时或将来时,宾语从句的时态一般不受主句的时态所影响.
当主句为过去时
①从句用一般过去时或过去进行时表示与主句谓语动词动作同时发生
②从句过去完成时表示该动作发生在主句谓语动作之前
③从句谓语用过去将来时表示该动作发生在主句谓语动作之后
④如果从句是一个客观真理，那么从句的时态不根据主句的时态而变化
⑤当宾语从句的引导词是who,which,what,when,where,how,why等表疑问时，不能按正常语序安排，经常将这类引导词置于句首
无论任何时候都为陈述语序.但也有部分口语提问例外 E.G:What's the matter?What's wrong with you?
