高中英语疑难探究Idon'tknow也是一种插入语素材
I don't know也是一种插入语“I don't know也是一种插入语”，这个命题对不对？“特殊疑问句”，是说话人想从对方那里得到答案（这个答案不是Yes和No，而是具体的内容）。
特殊疑问句中，最典型的放在特殊疑问词之后的插入语，就是Do you think。
例如：What do you think will happen next? 你认为接下来会发生什么？Who do you think will win the first prize? 你认为谁会获得一等奖?How do you think the war broke out? 你认为那场战争是怎样爆发的?When do you think China will host the World Cup? 你认为中国何时会举办世界杯?Where do you think we can get this machine? 你看我们在哪儿能搞到这种机器?Why do you think most of children like cartoon? 你认为为什么孩子们喜欢卡通?Which do you think is the best way to spend the money? 你们觉得花这笔钱最好的方法是什么？之所以认定Do you think为插入语，是因为Do you think并没有改变特殊疑问句的意义，只是改变了句子原有的结构（实际上，当特殊疑问词作主语时，加了Do you think也没有改变句子语序，例如：What do you think will happen next? 去掉Do you think，语序不变：What will happen next?）。
如果以上所有句子都去掉Do you think，那么意思没有变化。
Do you think只为强调说话人征求对方的看法而已。
除此之外，I don’t know也可以跟特殊疑问句连用，相当于一个插入成分。

I don't know可以作为插入语使用(二)
I don't know可以作为插入语使用（二）题外话：“I don’t know也是一种插入语”，作者不惜篇幅去论证这个问题，旨在为了帮助网友正确理解一道试题，同时排除该题是“错综时间虚拟条件句”这个说法。
下面，是网上流传的一道英语试题：Thank you very much indeed. If it had not been for your advice I really _____ what I should have done.A.do not knowB.have not knownC.had not knownD. would not have known.（答案：选A）该题目的命题者，可能是出于猎奇的心理，或者说有点挖空心思。
为了制造麻烦，选取了一个与虚拟句无关的插入语I don’t know 为选择题。
追根求源，这个句子来自《牛津英语用法指南》(261条，P 340 )，是if用法条目下If it had not been for的一个例句，Thank you very much indeed.这句话原来没有，是命题人加上去的。
因为这个句子的出处没有问题，而且颇具权威性，所以，有人拿来作为命题的题干，目的是给学生增加迷惑度。
原句是：If it hadn’t been for your help, I don’t know what I’d have done. 要不是你的帮助，真不知道我当时会怎么办。
如果把插入语I don’t know放在句首，则很容易理解：I don’t know what I would have done if it hadn’t been for your help.或者直接删去不用，句子意思仍然保持不变：What would I have done if it hadn’t been for your help?无独有偶，《柯林斯高级英语词典》上也有这样一句：If we had been spotted at that point, Idon’t know what would have happened to us. 如果当时我们被发现了，我不知道会有什么后果。

变换语序的方法和技巧
变换语序的方法和技巧变换语序是指在不改变句子原意的情况下，对句子中的词语或短语进行重新排列。
这种方法在写作或口语中经常使用，可以使表达更加丰富和有趣，同时也有助于加强逻辑关系和语法结构。
以下是一些变换语序的方法和技巧：1. 将主语和谓语互换位置：将谓语动词提前，主语后置，以形成倒装句。
例如：He is coming. → Is he coming?2. 将否定词提前：将句子中的否定词或短语提前，以强调否定意义。
例如：I don't know the answer. → The answer I don't know.3. 使用被动语态：将主动语态的句子改为被动语态，可以突出强调句子中的宾语。
例如：They built the bridge in 2000. → The bridge was built in 2000.4. 使用强调句型：利用强调句型（It is / was...that / who...）突出强调句子中的某一部分。
例如：She told me the truth. → It was she who told me the truth.5. 调整状语、定语或从句的位置：将句子中的状语、定语或从句提前或后置，以改变句子的重心。
例如：He left the room when the phone rang. → When the phone rang, he left the room.6. 使用同位语：用一个名词或名词短语来解释或限定另一个名词，以增加信息量。
例如：The city of Paris is beautiful. → Paris, the city, is beautiful.7. 使用非谓语动词：用动名词、分词或不定式替代原句中的谓语动词，以简化句子结构。
例如：He likes to play basketball. →He likes playing basketball.8. 替换连接词：使用不同的连接词，可以改变句子之间的逻辑关系。
六年级英语插入语理解运用判断单选题20题
六年级英语插入语理解运用判断单选题20题1. “What a beautiful day, isn't it?” “Yes, it is. The weather is really nice.” In this sentence, “isn't it” is an example of an insertion.A. Yes, it is.B. No, it isn't.C. I don't know.D. Maybe.答案：A。
“isn't it”在这里是反意疑问句的插入语，对前面的陈述句“What a beautiful day”进行反问，期望得到肯定或否定的回答。
根据后面对话“Yes, it is.”可知选A。
这种插入语的作用是加强语气，确认说话人的观点，并且引起对方的回应。
在语法上，反意疑问句由两部分组成，前面是陈述句，后面是简短的疑问句，通常遵循“前肯后否，前否后肯”的原则。
2. “I think, John is a very nice person.” In this sentence, “I think” is an insertion.A. John is nice.B. John is not nice.C. I don't know if John is nice.D. Maybe John is nice.答案：A。
“I think”在这里是插入语，表示说话人的观点或看法。
整个句子的意思是“我认为约翰是一个非常好的人”。
插入语“I think”不影响句子的主要结构和意思，只是表达说话人的主观想法。
所以选A。
这种插入语在语法上通常放在句子的开头或中间，用逗号与其他部分隔开。

i don't know主谓宾
I don't know主谓宾
句子"I don't know" 是一个英语中常见的简单陈述句，由主语、谓语和宾语构成。
让我为您分解它：
1. 主语(Subject)："I"，这是句子中的主语，代表了说话者自己。
2. 谓语(Verb)："don't know"，这是谓语，表示了动作或状态。
在这里，"don't" 是缩写形式，代表"do not"，而"know" 是动词，表示知道或了解的动作。
3. 宾语(Object)：在这个句子中，没有直接的宾语。
这是因为这个句子是一个疑问句，它在询问某人是否知道某事，而没有具体的宾语。
所以，总的来说，"I don't know" 是一个简单句子，主语是"I"，谓语是"don't know"，没有明确的直接宾语。
它用来表达不知道或不了解某事的情况。

一、选择题1．Hi, Simon. I hear that you’ve just come back from Korea. I’m calling to ask______________. A．how did you visit the city B．how many days you’ve spent there C．which hotel you stayed in Korea D．how you found the popular local food D解析：D【解析】【分析】【详解】句意：嗨，西蒙。
我听说你刚从韩国回来。
我打电话来是想问一下你对当地受欢迎的食物感觉如何。
考查宾语从句。
ask后是宾语从句，宾语从句是陈述语序，排除A；根据前文可知，西蒙已从韩国返回，而B选项是现在完成时（表示说话时还在韩国），故排除B；C 项中，stayed是不及物动词，其宾语是名词hotel，那么此时stayed后应加介词at，排除C。
D项中，found是find的过去式，意为“认为”。
故选D。
2．I don't know _____ the opening show tomorrow. Can you tell me?A．when we started B．when did we startC．when we will start D．when will we start C解析：C【解析】【详解】句意：我不知道我们的开场秀明天什么时候开始。
你能告诉我吗？考查宾语从句。
主句是一般现在时，根据时间状语tomorrow可知，从句时态要用一般将来时，排除AB；宾语从句要用陈述语序，所以助动词will要放在主语we之后，D项错误，故选C。
3．—Could you tell me__________so early yesterday?—Yes. To cook for my mom. It was her birthday.A．how did you come home B．how you came homeC．why you came home D．why did you come home C解析：C【解析】【详解】句意：——你能告诉我你昨天为什么提前回家吗？——是的，为了给我妈妈做饭，今天是她的生日。

I don't know可以作为插入语使用（一）
“I don’t know也可用作插入语”，这个命题对不对？
“特殊疑问句”，是说话人想从对方那里得到答案（这个答案不是Yes和No，而是具体的内容）。
特殊疑问句中，最典型的放在特殊疑问词之后的插入语，就是Do you think。
例如：
What do you think will happen next? 你认为接下来会发生什么？
Who do you think will win the first prize? 你认为谁会获得一等奖?
How do you think the war broke out? 你认为那场战争是怎样爆发的?
When do you think China will host the World Cup? 你认为中国何时会举办世界杯? Where do you think we can get this machine? 你看我们在哪儿能搞到这种机器?
Why do you think most of children like cartoon? 你认为为什么孩子们喜欢卡通? Which do you think is the best way to spend the money? 你们觉得花这笔钱最好的方法是什么？
之所以认定Do you think为插入语，是因为Do you think并没有改变特殊疑问句的意义，只是改变了句子原有的结构（实际上，当特殊疑问词作主语时，加了Do you think也没有改变句子语序，例如：What do you think will happen next? 去掉Do you think，语序不变：What will happen next?）。
如果以上所有句子都去掉Do you think，那么意思没有变化。
Do you think只为强调说话人征求对方的看法而已。
除此之外，I don’t know也可以跟特殊疑问句连用，相当于一个插入成分。
跟Do you think 不同的是，特殊疑问句是它的宾语从句。
例如：
A. What will happen next?
B. I don’t kno w what will happen next.
这两句在意思上没有什么差别：都是表达了“我不知道未来会发生什么”。
只不过句子形式不同，句A是特殊疑问句，句B是陈述句。
我们再看下面一组句子
第一组：（含特殊疑问词what）
1. What will become of us if the war breaks out? 如果战争爆发我们会怎样?
2. I don’t know what will become of us if the war breaks out.
3. If the war breaks out, I don’t know what will become of us.
第二组：（含特殊疑问词who）
1. Who will care for him if his wife dies? 假若他妻子死了，谁照顾他?
2. I don’t know who will care for him if his wife dies.
3. If his wife dies, I don’t know who will care for him.
第三组：（含特殊疑问词when）
1. If we offer you the job, when will you be free to join us? 如果我们给你这个工作，你什么时候可以到我们这儿来。
2. I don’t know when you will be free to join us if we offer you the job.
3. If we offer you the job, I don’t know when you will be free to join us.
第四组：（含特殊疑问词where）
1. If I believe this thought, where will it lead me? 如果我相信这个想法，它将把我带往何处?
2. I don’t know where it will lead me if I believe this thought.
3. If I believe this thought, I don’t know where it will lead me.
第五组：（含特殊疑问词how）
1. How will he survive if he can’t beg? 如果他不能乞讨，他将如何生存?
2. I don’t know how he will survive if he can’t beg.
3. If he can’t beg, I don’t know how he will survive.
【分析探究】以上5组句子，分别含有特殊疑问词what, who, when, where, how。
综合特点分析如下：
1. 句1，是一个含有if条件句的复合句，主句是特殊疑问句形式。
2. 句2，是在这个复合句之前加了I don’t know。
这样，复合句变成了I don’t know的宾语从句。
3. 句3，如果说句2中的I don’t know还不算真正的插入语的话，那么，句3中的I don’t know放在了if从句之后、主句之前，就变成了地地地道的插入成分。
再从If 从句和主句的意思关联看，I don’t know并非是If从句的主句，它与If 从句的内容毫不相干。
如：If his wife dies, I don’t know who will care for him. 这个句子中，条件句If his wife dies跟主句who will care for him的意思有关，跟I don’t know无关。
也就是说，If his wife dies是who will care for him的条件状语，不是I don’t know的条件。
这再次证明了I don’t know是插入成分。
