1、学习-好资料上海中考英语句型转换讲解与练习【考点讲解】一、肯定句改为否定句在做此类题时，通常在系动词、助动词和情态动词后加not(nt)。如果句中没有这些词，则根据谓语动词的原形、第三人称单数动词形式或过去式而分别在其前面加donot(dont),doesnot(doesnt)或didnot(didnt),并将第三人称单数动词形式或过去式改为原形。如：Wecanfinishtheworkthisafternoon.Wecantfinishtheworkthisafternoon.Theyputthebasketunderthetreejustnow.Theydidntputthebasketu
2、nderthetreejustnow.注意：1.当think,believe,suppose等动词后面跟宾语从句时，通常用否定主句谓语动词来达到否定从句谓语动词的目的。如：Ithinktheycancometonight.Idontthinktheycancometonight. 2.当must表示推测，表示“一定；肯定”的含义时，否定句应用cant。如：Hemustbeintheroom.Hecantbeintheroom.二、陈述句改为疑问句陈述句改为疑问句一般有三种情况：一是改为一般疑问句，二是改为反意疑问句。如:1.Thestudentshadlearnedabout1,000Engl
3、ishwordsbytheendoflastterm.（改为一般疑问句）Hadthestudentslearnedabout1,000Englishwordsbytheendoflastterm?2.ThetwinshaveneverbeentotheSummerPalace,havethey?（完成反意疑问句）三、对划线部分提问对划线部分提问，就是用一个合适的疑问词去替代句中的某一成分，使之成为一个特殊疑问句。当对主语或主语的定语提问时，用陈述句语序。对定语提问时，所修饰的名词应放在疑问词后。对其他成分提问，用“疑问词+一般疑问句语序”。如：1. Tomwillbebackintendays
4、.（对划线部分提问）Whowillbebackintendays?2.Hewritestohisfatheronceamonth.（对划线部分提问）Howoftendoeshewritetohisfather?四、同义句改写1根据句意改写主要考查学生对句意的理解和用一个词或一种结构来概括上句的意思的综合能力。如：1.LiHuaandZhangMingarethesameage.LiHuais_ZhangMing.【答案】asold/youngas。第一句的意思是“李华和张明同岁”，第二句是说“李华和张明年纪一样大”。2.HowmanypeopleliveinFrance?_thepopulat
