八年级英语下册句型转换练习题：一般疑问句、否定句、对划线部分提问和同义句一：变一般疑问的方法：1.当句中谓语动词是Be(am,is,are,was, were,)动词的时候，把Be(am,is,are,was, were)动词提前放于句首大写.2.当句中谓语动词前有情态动词时候，把情态动词（can, could, may,must,would，shoul,will，might….）提前，放于句首大写。
3.当句中谓语动词不是Be动词和情态动词的时候，通常在句首加Do、Does或Did，后面的动词用原形。
过去时用Did; 一般现在时，当主语是第三人称单数(He, She,It, 或单个的人或物)的时候用Does，其它都用Do。
注意：1.通常some改为any, too改为either，already 改为yet.2. 人称变换：一变二（I’m、We’re 改为Are you；my、our改为your.），二变一（You改为I、We，your改为my、our），三不变。
二：变否定句的方法：1.当句中谓语动词是Be(am,is,are，was, were)动词的时候，直接在Be(am,is,are,was, were)动词后加not, 通常缩写。
2.当句中谓语动词前有情态动词时候，在情态动词（can, may, must, could,would,will,might…..）后加not, 通常缩写。
3.句中谓语动词不是Be动词和情态动词的时候，通常在动词前面加don’t、doesn’t或didn’t，动词用原形。
过去式用didn’t; 一般现在时，当主语是第三人称单数(He, She,It, 或单个的人或物)的时候用doesn’t，其它都用don’t. 三: 对划线部分提问的方法：一定：定特殊疑问词，即根据划线部分内容确定特殊疑问词。
二改：把剩下的句子改为一般疑问句。
