最新小学英语必考知识点(2)
(2)确定助动词用do、does还是did，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，动词用过去式的助动词就有did。
(3)把助动词后提到句首。
(4)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。
三、特殊疑问句。
表示疑问，有疑问词(在开头)，回答有很多种可能。
常用疑问词：
What、When、Which、Who、Whose、Why、How
如何对划线部分提问：
1、将原问句翻译为汉语(在读中要将划线部分重读)。
如：His birthday is on the 5th of May .
他的生日在五月五日。
2、用汉语进行提问。
如上句，应该问：他的生日在什么时候?
3、根据汉语将所要提问的句子补充完整。
如上句When is his birthday ?
四、祈使句
表示请求或命令别人做某事或不要做某事。
肯定祈使句一定是以动词原形开头(有时有please)，否定的祈使句一定是don’t加动词原形开头(有时有please)。
把祈使句改为否定句只需在动词前加don’t即可。
