____ receiving the book, she went over the most interesting chapters first
answer 🤖
In ❌
答案: On
on除了表示“在..上”,还可表示“就在...之后,一.就”; 此外空格后的动词用了动名词,也可提醒此处很可能用介词。
翻译: 一收到书她就首先看了那些最有趣的章节。
重点在"一...就"
关键语法点:介词on表“一...就”的用法
正确答案:On
错误选项:In
深度解析
on + doing 的固定搭配
- 结构:On + 动名词(doing)
- 含义:表示“在...之后立即做某事”或“一...就...”,强调动作的紧接性。
- 例句:
- On hearing the news, she burst into tears.
(一听到消息,她立刻哭了起来。) - On arriving at the airport, he called his family.
(一到机场,他就给家人打了电话。)
- On hearing the news, she burst into tears.
错误选项 "in" 的排除
- in + doing 表示“在做某事的过程中”,强调动作的持续性,与题意矛盾。
- ❌ 错误句:
In receiving the book, she went over the chapters...
→ 暗示“她在收书的过程中就开始看章节”(不符合逻辑)。

|---|---|---|---|
| On | 一...就(立即) | On opening the box, she found a gift. | ✅ |
| In | 在...过程中 | In reading the book, she took notes. | ✅ |
| In | ❌ 本题场景 | In receiving the book, she read chapters... | ❌(动作无法同时持续) |
隐藏考点:动名词前的介词选择
- 动名词(receiving)作宾语时,前面必须有介词(如on, in, after等),根据句意选择合适介词。
- 类似结构:
- After finishing the work, he left.(完成工作后离开)
- By practicing daily, she improved.(通过每天练习进步)

“On加doing表立即,动作紧接莫迟疑;
In表过程持续中,前后逻辑要理清!” ✨
