五年级英语重点必备语法

小学五年级英语一般疑问句语法 一般疑问句 如何将一个肯定的陈述句改为一般疑问句： 1、看句中有无 be 动词，如有，把 be 动词提到句首即可。 2、看句中有无情态动词，如有，把情态动词提到句首即可。 3、如上述二者都没有，就应把助动提到句首。分四个步骤： (1)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。 (2)确定助动词用 do 还是 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 (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。 小学五年级现在进行时语法 表示现在正在进行的动作。 构成： 主语+bebe 动词+be动词的现在分词+be其它成分 We are having lunch.
