I know that your father is a doctor. Betty thinks that it is going to rain this afternoon. b. He asks whether/if well go fishing on Sunday. He doesnt know whether /if they will plant trees on Saturday or not. c. He asks where the nearest book shop is. Can you tell me how I can get to the station? (2)归纳：请仔细观察以上例句，回答下列问题:以上三组例句均属宾语从句, 宾语从句由哪些连词引导？ 【合作探究 交流展示】宾语从句的具体用法如下：（一）宾语从句通常由以下连词所引导：（1）由_引导时，它无实义，常省略。例如：She says _ she will leave a message. 她说她将留言。（2）由_或_ 引导。其意义是_ 例如：He asked me if/whether I could speak English. 他问我是否会说英语。I wonder if/whether he is a teacher. 我想知道他是否是一名教师。（3）由连接代词（what, which, who, whom, whose）或连接副词（how, where, when, why）引导的宾语从句。例如：I cant understand _ you said. 我不能理解你说的话。He wanted to know _the building would be set up. 他想知道这座楼房何时建成。（二）主句与宾语从句的时态关系 主句与宾语从句的时态关系有以下三种情况：（1）若主句用了现在时，则宾语从句可用其所需要的任何时态。例如：I think he often _ books. ( read ) 我认为他经常读书。I think he _ here tomorrow. ( come) 我认为明天他会来这儿。He says that they _in Tokyo yesterday. (arrive )他说他们昨天到达了东京。Im sure that Linda _ there before. ( be ) 我确信琳达以前去过那儿。（2）若主句用了过去时，则宾语从句需用 过去时态（一般过去时、过去进行时、过去将来时、过去完成时）的某种形式。例如：He said he _ right. ( be ) 他说他是正确的。He said he _ TV at that time. ( watch) 他说在那时他正在看电视。Tom told me that he _ to Mount Tai. ( travel ) 汤姆告诉我他将去泰山旅游。（3）若宾语从句陈述的是 客观真理、客观事实、科学原理、格言、谚语等，则不受主句时态的限制，通常用 一般现在时。例如：The teacher told us that the earth _round the sun. ( move)老师告诉我们地球绕着太阳转。He said one and one _ two. ( be) 他说一加一等于二。 (4) 注意语序, 无论从句是什么句式，宾语从句必须是_语序。Did you hear what I had said?I want to know if the train leaves at six p.m.He asked who the boy was looking for.I dont know when he arrived. (5)if和whether引导宾语从句通常可互换，但在下列情况下只可用whether。介词后的宾语从句直接与or not连用在带to的不定式前Im thinking about_(whether/if)we should go fishing.I dont know_(whether/if)or not he passed the exam.She hasnt decided_(whether/if)to go or not. (6) 宾语从句与简单句的转换由特殊疑问句引导的宾语从句，当从句主语与主句主语一致时，宾语从句常简化为_的形式。I dont know what I should do.=I dont know_ _ _.John didnt decide which book he would buy.=John didnt decide_ _ _ _.Could you tell me how I can get to the station?=Could you tell me _ _ get to the station?Could you tell me where we show our tickets?=Could you tell me_ _show our tickets?Could you tell me how to get to the nearest underground station?=Could you tell me_ _ _get to the nearest underground station?【精讲点拨 释疑解难】宾语从句：在复合句中作宾语的名词性从句，通常放在主句谓语动词（及物动词）或介词之后。带有宾语从句的复合句就是用连接词把一个主句和一个宾语从句连接在一起。宾语从句的连接词可分为以下几类：1) that引导的宾语从句,that在句中只起连接作用，无具体意义，不作句子的任何成分，一般可以省略。2) Whether/if引导的宾语从句,作“是否”讲，在句中起连接作用，不作任何成分。3) 特殊疑问词引导的宾语从句（when where why how what who which whose whom） 连接代词what which who whom不仅起连接作用，还在句子中作主语，宾语或表语。连接副词when where why how分别在句子中作时间，地点，原因和方式状语。连接词whose which在句中作定语。宾语从句的时态1)在宾语从句中，若主句的谓语动词是一般现在时，从句可根据需要用任何时态. 2)在宾语从句中，若主语的谓语动词是过去时态，则从句必须用和过去相关的时态。宾语从句的语序应该用陈述句的语序，即“主语+谓语+宾语”的顺序排列。将疑问句转化为宾语从句时，一定要将疑问语序需转变为陈述语序。教学反思：_
