中考英语专项复习——宾语从句 【宾语从句命题】 中考对宾语从句的考查主要集中在以下几个方面： 1. 引导宾语从句的连词和代词选择； 2. 宾语从句的语序； 3. 宾语从句的时态。 【考点诠释】 宾语从句在初中英语语法中有着相当重要的地位，几乎每年的中考都有对宾语从句不同角度的考查。其考查的重点一般都集中在以下几个方面： 一、连接词 宾语从句的连接词分为三类： 1. 引导陈述句用纯连接词that（在口语或非正式文体中常常省略）。 2. 引导一般疑问句用if或whether，句中翻译为“是否”。 注意：下列几种情况通常使用whether：（1）在具有选择意义又有or或or not时，尤其是直接与or not 连用时，往往用whether；（2）在介词之后用whether；（3）在不定式前用whether等。 3. 引导特殊疑问句，只需用原来的特殊疑问词。（连接代词和连接副词，“黄金搭档”原则） 一Excuse me，could you tell me__________? ——There's a bank on the second floor．You can make it there．[黄冈市] A where I can change money B how I can get to the bank C if there's a bank near here D．where the bank is 二、语序 在含宾语从句的复合句中，不管主句是陈述句还是疑问句，从句一律是用―连接词＋陈述句语序‖，其标点符号由主句来决定。 1．--Do you know ______________now? 一In the People's Hotel．[北京市] A where is Tom working B where did Tom work C．where Tom is working D．where Tom worked 三、时态 1. 如果主句的谓语动词是一般现在时或一般将来时，宾语从句的时态可视情况使用任何一种相关的时态。 2. 如果主句的谓语动词是过去时态，宾语从句必须使用过去相应的某一种时态。 3. 如果宾语从句表示的是客观事实、普遍真理、自然现象或习惯性动作等，不管主句是用什么时态，从句时态习惯上都用一般现在时。 4. 情态动词could / would用于―请求‖，表示委婉、客气的语气时，从句时态不受主句的约束。 Excuse me, could you tell me when __the new Olympic Center? [沈阳市] A．are we visited B will we visit C we are visited D we will visit ----Could you tell me whom the radio _________by? 一Sorry，I have no idea．[福州市] A．invents B invented C is invented D．was invented （河北）I didn’t understand __________, so I raised my hand to ask.. A. what my teacher says B. what does my teacher say C. what my teacher said D. what did my teacher say 四、否定转移 当宾语从句表示否定的意义时，若主句主语为第一人称且谓语动词是think / believe / suppose / expect等时，应在主句上加以否定。 五、简化 宾语从句在一定条件下，可以简化为―特殊疑问词+不定式‖、―it +形容词+不定式短语‖、复合宾语、动词不定式（名词、动名词、形容词或副词、过去分词）短语、名词和过去分词等。 I don’t know what I should do with the le tter. （改为简单句）（山东烟台） I don’t know what ___________ ___________ with the letter. 六、注意点 if / when既可以引导宾语从句，也可以引导状语从句，应注意它们在两种从句中的意思和用法的不同。if / when引导宾语从句时，意思分别为―是否‖和―何时‖，此时它们的时态根据具体情况而定。if 和when引导状语从句时，意思分别为―如果‖和―当……的时候‖，此时如果主句是一般将来时，从句部分则用一般现在时。 七、综合考查 --Did Mr White tell you________-? --Yes. He said he went there in 2013. [福州市] A. when he traveled to Tibet B. how he goes to Wuhan C. Where he spent his holidays D. why did he visit Kunming 【语法回顾】 宾语从句 宾语从句是一种名词性从句，在句中作及物动词的宾语，或介词的宾语，或形容词的宾语。根据引导宾语从句的不同连词，宾语从句可分为三类。 1. 由that引导的宾语从句。That只有语法作用，没有实在的意义，在口语和非正式文体中可以省略。例如： He said (that) he wanted to stay at home.他说他想呆在家里。 She doesn’t know (that) she is seriously ill.她不知道她病得很严重。 I am sure (that) he will succeed.我确信他会成功。 2. 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？ He asked whose handwriting was the best.他问谁的书法最好。 Can you tell me where the No.3 bus stop is? 你能告诉我3路公共汽车站在哪儿吗？ I don’t know why the train is late.我不知道火车为什么晚了。 I can't imagine why he did that thing．我不能想像他为什么做了那件事。 Do you know why we have put off the sports meet till next month? 你知道我们为什么把运动会推迟到下个月吗? 以上两个例句的宾语从句相当于一个特殊疑问句，分别为：why did he do that thing?和Why have you
2018中考英语专题训练----句型转换 按括号内的要求转换句型，每空一词(含缩写） 1. Can he get to school on time? The boy`s mother worried about(合并为含有宾语从句的复合句) The boy` s mother worried about _______ he _______get to school on time. 2.I learn English by listening to the radio.
