特殊疑问词引导的宾语从句1.掌握特殊疑问词引导的宾语从句的基本构成及重点用法；2.能在具体的语境中灵活运用本节课的内容。
1. 疑问词引导的宾语从句当宾语从句是特殊疑问句时，疑问词就是引导词，这时疑问词不可省略，而且宾语从句要用陈述语序，即＂疑问词+主语+谓语+其他＂。
►I wonder what I should do next. 我想知道下一步我该做什么。
【警示】宾语从句的标点要根据主句的句子类型来确定。
当主句是陈述句时，句末通常用句点；当主句是疑问句时，句末通常用问号。
2. 含有宾语从句的复合句与简单句的转换含有宾语从句的复合句在一定的条件下可以转化为简单句。
（1）若主句的主语与从句的主语一致，则由疑问词引导的宾语从句可以变成＂疑问词+动词不定式＂的复合结构。
►I don’t know how I should do it next.=I don’t know how to do it next. 我不知道下一步应该怎样做。
（2）当主句谓语动词是see, hear, watch等时，其后的that从句常简化为＂宾语+动词原形/动词-ing形式＂。
►I saw some boys were playing basketball on the playground just now. I saw some boys playing basketball on the playground just now.刚才我看到一些男孩正在操场上打篮球。
（3）当主句的谓语动词是hope, agree, wish等，且主句的主语与从句的主语一致时，其后以that引导的宾语从句可简化为动词不定式结构。
►He agreed that he could help me with my English. He agreed to help me with my English.宾语从句除由引导词that，if/whether引导外还可由what，which，whom，when等引导。

例如:What's wrong with you? 怎么了? ——He asked the girl what was wrong with her.What's the matter? 怎么了? —— He asked the girl what was the matter.What has happened to him? ——We want to know what has happened to him.⼩试⽜⼑:1、I said to her、Where did you go during the holiday?2、Mr、Ding asked 、What did you do during the holiday?⼆、语从句的时态1.若主句为⼀般现在时或⼀般将来时,则从句的时态不限可视句⼦意义使⽤所需要的任何时态。

Can you tell me where the drugstore is? 你能告诉我药店在哪儿吗？He asked who could answer these questions. 他问谁能回答这些问题。

从学生角度分析为什么难
英语句型的转换和单独的时态问题就是学生学习的难点，而疑问句在宾语从句中的语序变化，以及在从句中要根据主句的时态变化而变化，就更让学生感到迷惑，难以掌握。
难点教学方法
1.通过视频，动画等情境教学，感悟宾语从句的语序、引导词、时态三要素的重点知识。
2.通过讨论及问题探究，能正确使用that, if/whether ,特殊疑问词引导的宾语从句。
（2）投篮游戏（一筐一球）活动，来编排宾语从句的语序。通过形象思维，激发学生的兴趣，
Step4.引导词
1.that引导的宾语从句
展示图片和句子Ibelieve(that)I can fly.引导学生分析宾语从句的特征：
★陈述句前用that引导
★that在句中无意义，可省略。
★从句部分为陈述语序。
2.if或whether引导的宾语从句
Step 3.宾语从句的语序 我是小神探
（1）鼓励学生当小神探，快速找到句子的宾语从句部分。探究主句、从句部分的语序。
He wonders if you hurt the girl.
He askswhatyou are doing
He wondershowhe can grow up
得出结论：主+谓+其它陈述语序
B以同样的教学方式，得出结论：
主句为一般过去时：从句用相应的过去的某一种时态

）你看，这个句子就像在探寻一个未知的宝藏，充满了好奇的感觉。
2. “where”引导的宾语从句呀，那可有趣了。
想象一下，你在找一个迷路的小伙伴，就像这样：She asked me where I had been.（她问我去了哪里。

这就好比是在时间的长河里捞鱼，你永远不知道会捞到哪条。

1 . 由陈述句变化而来用that引导, that 可省略；
2 . 由一般疑问句变化而来, 用if或whether 引导；
3. 由特殊疑问句变化而来, 用该特殊疑问词引导。
如：when ,where, how, why。
If whether 引导一般疑问句的宾语从句
He said, “I like playing basketball.”
He said that he liked playing basketball.
1. .that 引导陈述句的宾语从句
He asked me, “Do you like playing basketball?”
He asked me if I liked playing basketball.
2. if 或whether 引导一般疑问句的宾语从句；
He asked me, “Where do you play basketball?”

全新英语语法——宾语从句
全新英语语法—宾语从句用一个句子作宾语，这个句子就是宾语从句。
宾语从句的三大考点是时态、语序和引导词。
15-1 宾语从句的引导词在含有宾语从句的复合句中，主句与从句之间要有一个连接词来引导从句，这个连接词称为宾语从句的引导句。
宾语从句的引导词分三类，一是连接代词that，二是连词if和whether，三是特殊疑问句。
1.that引导的宾语从句宾语从句是陈述句时，用连词that引导。
that在从句中只起引导作用，没有词义，不做句子成分，在口语中常常省略。
如：We believe that he is honest.I suggest that we should go tomorrow,We learnt from his letter that he was in Spain.I didn't know (that) he was LiLei.She said that she would come to the meeting.I promise you (that) I will be there.2. if/whether引导的宾语从句当宾语从句是一般疑问句时，从句要用if或whether引导， if和whether 意为“是否”，在句中不做句子成分，也不能省略。
I asked him if he was busy.I asked him whether he was coming.I don’t know if (whether) he'll arrive in time.I didn’t know whether they liked the place.I wonder if it's large enough.She didn't say if he was still alive.I don't know whether he'll arrive in time.I asked her whether she agreed.[辨析]if和whether的用法区别:if引导宾语从句，意思是“是否”，可与whether互换使用，if往在口语中用得较多,whether 多用于书面语及正式的场合。
新概念英语第一册语法知识点宾语从句
新概念英语第一册语法知识点：宾语从句宾语从句一、重要语法：宾语从句1、宾语从句本课侧重的是由特殊疑问词引导的宾语从句的用法，主要的疑问词有if/whether/how/why/what/when/where等。
如：I don't know when I'll finish.My wife wants to know if Mary needs any help. I don't know what you're talking about.二、课文主要语言点Is that you, John? Yes, speaking. 注意打电话时的习惯用语。
如果电话接通后，要找某人接电话，一般可以说：May Ispeak to sb.? 也可以像课文里这样直接询问对方是否就是你要找的人：Is that you, sb.?如果接电话的人正是对方要找的人，则可回答：This is sb.speaking.或者简单回答：Speaking。
原文中的speaking就是简短回答，其完整形式为：This is John speaking.Tell Mary we'll be late for dinner this evening. 1)tell sb.sth.，tell为双宾动词，可以改为：tell sth. to sb.。
但是，当直接引语为句子时，只能用tell sb. sth.(从句)的结构2)belate for，迟到。
I'm afraid I don't understand. I'mafraid后接宾语从句，省略了连接词that。
这是形容词后接宾语从句的用法，that 一般都会省略。
如：I'm sure he will come hereon time tomorrow. 需要注意的是，当I'mafraid要翻译成中文时，不要译为“我恐怕”，而要译为“恐怕”，这样比较符合中文的表达习惯。

特殊疑问词引导的宾语从句语法点，考点很多。
那么，除了上面这一点，大家还能说出多少呢？语法知识不系统，是我们大家普遍存在的问题，今天我们就在这里给大家全面归纳，相信读完你定会有所收获，可以收藏或者分享给更多需要的朋友。
引导宾语从句的特殊疑问词可以分为连接代词和连接副词。
连接代词有：what, who, whom, whose, which；连接副词有：when, where, why, how等，这个大家比较好理解，就是我们经常说的疑问代词和疑问副词。
大家要注意以下几个考点：1、当连接代词和连接副词来引导宾语从句的时候，因为它们在从句中是充当某个成分的，所以不能省略。
（我们都知道that引导的宾语从句，that是可以省略的。
）例句解析：2、由特殊疑问词引导的宾语从句，含有疑问语气，要用陈述语序。
从句的结构为：连接词+主语+谓语+其他。
例如：3、当what, who等特殊疑问代词，在特殊疑问句中充当主语的时候，特殊疑问句本身就是陈述语序，这样的句子语序不需要有变化。
如下面两个例子：4、如果主句是一般现在时，宾语从句的时态原则上不受主句的影响；如果主句是一般过去时，宾语从句通常要用过去的某种时态。
看下面例句解析：Can you tell me why she is crying？你能告诉我她为什么哭吗？I didn’t know which coat he liked？我不知道他喜欢哪件外套？大家看第一个例句，主句是一般现在时，从句仍然用一般现在时；第二个例句，主句中的didn’t可以判断是一般过去式，从句用一般过去时。
5、直接引语变间接引语：从句的主语如果是第一人称，变宾语从句要与主句的主语一致；如果是第二人称，要与主句的宾语一致；如果是第三人称，而不需要改变。

宾语从句正确引导和使用直接和间接宾语从句
宾语从句正确引导和使用直接和间接宾语从句在英语中，宾语从句是指作为宾语的句子。
宾语从句可以分为直接宾语从句和间接宾语从句。
直接宾语从句是指宾语从句直接引导整个句子的动词，而间接宾语从句是指宾语从句作为双宾语中的间接宾语。
在使用宾语从句时，我们需要注意正确选用引导词以及合理使用从句的结构。
本文将就宾语从句的正确引导和使用进行探讨。
一、直接宾语从句的引导词1.连词“that”在大部分情况下，直接宾语从句可以用连词“that”来引导，而且在口语和书面语中都很常见。
例如：Tom said that he would come to the party.Lisa knows that the concert starts at 7 pm.2.连词“if/whether”当宾语从句是对于某事的疑问或选择时，我们可以使用连词“if”或“whether”来引导宾语从句。
其中，“whether”更加正式，适用于正式场合或较为严谨的语境。
例如：Henry asked if/whether Peter had finished his homework.The teacher inquired whether the students had studied for the exam.3.特殊疑问词特殊疑问词可以引导宾语从句，用于询问特定信息。
例如：Can you tell me where the nearest post office is?Do you know how much the tickets cost?二、直接宾语从句的结构直接宾语从句通常由主语、谓语和宾语从句三部分组成。
在引导词后面紧接着宾语从句，不需要使用逗号进行隔开。
例如：I believe that you will succeed.She thinks she is a good singer.三、间接宾语从句的引导词间接宾语从句出现在双宾语动词后面，它告诉我们给予或交付的对象。

特殊疑问词引导的宾语从句
一、宾语从句的引导词：
由连接代词who, whom, whose,what,which 和连接副词when, where, why, how 引导的宾语从句。
这些连接代词和连接副词
在宾语从句中充当某个成分。
例如：Do you know who (whom) they are waiting for? 你知道他们
在等谁吗？I can't imagine why he did that thing ．我不能想像他为什
么做了那件事。
注意：
（1））由于宾语从句要求陈述句语序，故而在从句中它变成了陈述语序。
请看下列两组句子：How much does this coat cost? ——I want to know how much this coat costs ．Where did you go yesterday? ——Please tell me where you went yesterday ．
（2））当疑问代词w hat ，who 在特殊疑问句中做主语时，该特殊疑
问句本身就是陈述句语序，所以当该句用来做宾语时，语序不需要
调整。
例如：What's wrong with you? 怎么了? ——He asked the girl what was wrong with her ．What's the matter? 怎么了? ——He asked the girl what was the matter ．What has happened to him? ——We want to know what has happened to him ．小试牛刀：1. I said to her. Where did you go during the holiday? 2.Mr.Ding asked . What did you do during the holiday?
二、宾语从句的时态
1. 若主句为一般现在时或一般将来时，则从句的时态不限可视句子意义使用所需要的任何时态。
例如：Don't you think Jim is speaking too quick. 难道你不认为吉姆讲的太快了吗？He says he will come back. 他说他会回来。
2. 若主句是祈使句，从句谓语动词也可用所需要的任何时态。
例如：Show me which picture is yours. 让我看看哪张照片是你的。
Please tell us where we will go. 请告诉我要去哪里。
3. 若主句是一般过去时，从句必须用过去时态的某一种。
例如：
I knew she had swept the floor already.我知道她已经扫过地了。
He asked if I was doing my homework this time yesterday. 他问我昨天这个时候是否在做作业。
4. 若从句叙述的是客观真理、自然现象或永恒不变的规律时，则不受主句时态的限制，仍用一般现在时。
例如：Our teacher told us light travels much faster than sound. 老师告诉我们光传播的速度比
声音快得多。
They knew the sun is much bigger than the earth then. 他们那时就知道太阳比地球大得多，He said that one and one makes two. 他说一加一等于二。
小试牛刀：
1、The radio says it cloudy tomorrow. (be)
2、The headmaster hopes everything well. (go)
3、I hear they it already. (return)
4、He said that they members of the Party since 1948. (be)
5、Our teacher told us in class the sun in the east. (rise)
