关于“where”的简略回答，综合搜索结果分析如下：

一、简略回答的基本规则

省略介词

在回答“where”引导的疑问句时，通常省略介词“in”或“at”，直接以地点名词或副词作答。例如：

- Where's the book？ → The book is on the table.

- Where did you call him？ → I called him at home.

使用代词

可以用代词替代地点名词，使回答更简洁。例如：

- Where is the meeting？ → It's in the conference room.

- Where did we meet？ → We met at the park.

二、常见用法示例

直接回答地点

- Where is your wallet？ → It's in my purse.

- Where did we go last night？ → We went to the movies.

使用介词短语

有时需用介词短语补充说明地点，例如：

- Where is the nearest subway station？ → It's two blocks away.

三、注意事项

疑问句与陈述句的区别：

疑问句需用疑问词+助动词/情态动词+主语结构，而陈述句直接用主语+谓语。例如：

Where is the library？ [疑问句]

The library is on the corner. [陈述句]

特殊场景：

当需要强调地点时，可用“where it is”结构，例如：

The letter is where I left it. [强调地点]

通过以上规则和示例，可灵活掌握“where”的简略回答方式。
