小升初英语总复习-句法课件(全国通用)

小升初语法总复习--句法一、句型（一）肯定句（二）否定句be动词（am、is、are）+not、

情态动词can+not、

助动词（do、does）+not如何将一个肯定的陈述句改为否定句：1.看句中有无be动词，如有，直接在be动词后+not。2.看句中有无情态动词，如有，直接在情态动词后+not。3.如上述二者都没有，就应用助动词+not。（三）一般疑问句

肯定陈述句中本来是没有助动词的，要加上去，位置在主语（某人或某物）后，动词前。确定助动词用do、does，根据句中动词，动词是原形的助动词就用do，动词是第三人称单数的助动词就用does，在助动词后加not。原句中动词假如发生变化就要恢复成原形。强调一点，有some的要考虑是否要用any。常用疑问词：Whattime什么时间问具体时间，如几点Who谁问人Whose谁的问主人Where在哪里问地点What什么问东西、事物（四）特殊疑问句
