句型转换 <br /> <br /> 句型转换这一题型是先给出一个句子，然后再给出一个包含几个空白处的句子，要求根据括号内的具体要求在第二句的空白处填入适当的词来完成。它有完全的句式转换和句子中某一部分或几部分的转换。该题型主要考查同学们的语言基础知识及句子结构的构成、变化、运用等。其特点是规律性强、灵活性小，旨在考查考生用不同的句型结构来表达相同、相近或相反的语意的能力，训练灵活运用语言的技巧。 <br /> 从题型上看，句型转换可分为两大类： <br />一是按要求改写句子。即按照指定要求将原句改写成其他形式的句子，如肯定句改为否定句，陈述句改为一般疑问句、特殊疑问句、反意疑问句、感叹句，对划线部分提问等。 <br /> 另一类是同义句、近义句的转换，即要求用不同的句型，不同的语言手段表达相同的思想。 <br /> 本期我们先来看看按要求改写句子的具体情况。同义句、近义句的转换我们将在 下一期做详细介绍。 <br />按要求改写句子 <br />按要求改写句子的具体分类如下： <br />一、肯定句改为否定句 <br />1. 改变谓语结构 <br />在系动词be, become, feel, smell等，助动词be, have, do 等以及情态动词can, may, should等后加not。如果句子的谓语中不是以上这些词，而是行为动词，则相应地将动词的原形，第三人称单数或过去式变为否定形式。如： <br />He has seen the film before. <br />→He hasn’t seen the film before. <br />He will write the book in two months. <br />→He won’t write the book in two months. <br />He does his homework in the evening. <br />→He doesn’t do his homework in the evening. <br />2. 用含否定意义的词（如never, nothing, nobody, none, neither, little, few等）。 <br />（1）always / ever →never, and →or。如： <br />He was always late for school last term. <br />→He was never late for school last term. <br />（2）too→not…either, already→not…yet。如： <br />He goes to school by bike, too. <br />→He doesn’t go to school by bike, either. <br />（3）all→none, both→neither, both…and →neither…nor，此时，谓语动词仍用肯定形式，但当neither作主语，谓语动词用单数形式；“neither …nor…”连接两个主语时，谓语动词应和靠近它的主语保持一致。如： <br />He knows all of the workers here. <br />→He knows none of the workers here. <br />Both of the twins are from England. <br />→Neither of the twins is from England. <br />3. 当think, believe, suppose等动词后面跟宾语从句时，通常用否定主句的谓语动词来达到否定从句谓语动词的目的。如： <br />I think they can come tonight. <br /> <br />→I don’t think they can come tonight. <br />二、陈述句改为疑问句 <br />1. 一般疑问句。 <br />Sam often does his homework in the evening. <br />→Does Sam do his homework in the evening? <br />2. 特殊疑问句。 <br />I got there the day before yesterday. <br />→When did you get there? <br />3. 反意疑问句。 <br />Mary doesn’t work hard. <br />→Mary doesn’t work hard, does she? <br />注意：Let’s和Let us祈使句的附加问句分别为shall we 和will you。如： <br />Let”s go out for a walk, shall we? <br />三、陈述句改为感叹句 <br />The film is very interesting. <br />→How interesting the film is! <br />It”s a beautiful flower. <br />→What a beautiful flower it is! <br />一般情况下，what引导的感叹句和how引导的感叹句可相互转换。如： <br />How nice the watch is! →What a nice watch it is! <br />四、对划线部分提问 <br />就划线部分提问，是用一个合适的疑问词去替代句中的某一成分，使之成为一个特殊问句。其方法主要是：先依据语意选择相应的疑问词和疑问句语序，句末改用问号。这时我们要注意以下几点： <br />（1）选择恰当...
