Unit 2 You can make a difference

专题02 语法提升·易错题专项训练

询问某人做了什么及其答语

询问某人过去做了什么，是一般过去时的核心交际句型，核心标志是用助动词 did 构成疑问句，答语需使用实义动词的 过去式（规则变化加 - ed，不规则变化需单独记忆）。

特殊疑问句

What + did + 主语（人称代词 / 名词）+ 动词原形 + 过去时间状语？

（did 是助动词，无单复数变化，后接动词原形）

What did you do yesterday?（P12）

你昨天做了什么？

What did Lily do last weekend?（P12）

莉莉上周末做了什么？

答语（肯定 / 否定形式）

肯定答语：主语 + 实义动词过去式 + 其他.

I cleaned my room.（P12）

我打扫了我的房间。

She read a storybook.（P12）

她读了一本故事书。

否定答语：主语 + didn't + 动词原形 + 其他.

I didn't play basketball.（P12）

我没有打篮球。

He didn't watch TV last night.（P12）

他昨晚没有看电视。

关键用法（三步走判断）

第一步：锁定疑问词——询问“做什么”的动作，固定用 what 开头；

第二步：添加助动词did——did用于一般过去时疑问句，无论主语是单数还是复数，did 形式不变，且其后的实义动词必须变回原形；

第三步：答语动词变形——肯定答语用实义动词过去式，否定答语用 didn't + 动词原形。
