这是一道典型的完形填空（或语法填空）题目解析。根据提供的选项 A. on, B. by, C. for 以及答案 C，我们可以推断出这道题考查的是介词与时间段的搭配，对应的空缺处应该是文中的第 **3** 空。 以下是针对该题目的详细解析： ### 题目定位 **原句：** "I had been there ____3____ about two hours before an interesting car arrived." **选项：** A. on B. by C. for ### 解析过程 1. **分析句子结构与语境**： * 句子前半部分 "I had been there"使用了**过去完成时**，表示在“有趣的汽车到达”这一过去动作之前，作者已经在那里待了一段时间。 * 空格后面跟着 "about two hours"（大约两个小时这是一个**时间段/持续时间**。 2. **辨析选项用法**： * **A. on**：通常用于具体的某一天、日期或星期几（如 on Monday, on July 4th），或者表示接触表面。它不能直接接时间段来表示持续时长。 * **B. by**：通常表示“不迟于……”、“到……为止”或表示方式（通过……）。如果接时间点，表示截止期限（如 by 5 pm）；接时间段时通常不表示持续状态，而是表示幅度或方式，不符合此处语境。 * **C. for**：是英语中专门用来引出**动作或状态持续的时间长度**的介词。结构为 `for + 时间段`（例如：for two hours, for a long time, for three days）。 3. **结合语境判断**： * 句意是：“在那辆有趣的汽车到达之前，我已经在那里待了**大约两个小时**。” * 这里强调的是“待在那里”这个状态持续了多久，因此必须使用介词 **for**。 ### 结论 * **正确答案：C. for** * **完整句子：** I had been there **for** about two hours before an interesting car arrived. --- ### 知识点拓展 在英语中表示时间的介词区别： * **for + 时间段**：强调持续时间长短。（例：I slept **for** 8 hours.） * **since + 时间点**：强调从过去某一点开始一直持续到现在或过去某一时刻。（例：I have been here **since** 9 am.） * **in + 时间段**：通常用于将来时，表示“在……之后”；或用于过去时，表示“花费了……时间做完某事”。
