高中】Could it be in the restaurant (where) you had dinner with me yesterday (that) you lost you

Could it be in the restaurant (where) you had dinner with me yesterday (that) you lost you bag?
为什么是前面用where后面用that？

Answer 1

1. 第一个where用作引导定语从句的先行词，用以修饰the restaurant。此处也可用at which来替换where，定语部分不变。

2. 后面的that是一个固定用法，用于强调句式中，其基本形式为：

       It is + sb./sth./at sp.+  that + sb.+v(动词词组)。

       上面的问句就是由这个基本用法变形而来。

希望我的回答能对你有帮助。^-^
