Answer 1

这些词汇都是关于时间或地点的介词短语，它们在用法上有一些区别：
1. "in which"：用于引导一个定语从句，表示时间或地点的范围。例如："I visited Paris, in which I had a wonderful time."
2. "for which"：也用于引导定语从句，表示目的或原因。例如："He bought a gift for his sister, for which she was very grateful."
3. "on which"：同样是引导定语从句，强调特定的时间或日期。例如："The conference will be held on Monday, on which many experts will be present."
4. "at which"：也是引导定语从句，表示特定的时间或地点。例如："We will meet at the restaurant, at which we had our first date."
这些介词短语都可以用于修饰先行词，提供更多的信息。请注意，具体的用法会取决于句子结构和上下文。
