考查要点：本题主要考查学生对条件状语从句中"unless"的用法的掌握，要求学生能够将含有"if"的否定句转换为使用"unless"的等价表达。

解题核心思路：

1. 理解"unless"的含义："unless"相当于"if not"，表示"除非"，通常引导否定意义的条件。
2. 句型转换规则：若原句为"if + 主语 + 不定式否定形式"结构，可直接将"if"替换为"unless"，并去掉否定词（如"not"）。
3. 注意逻辑关系：转换后需确保主句与从句的逻辑关系不变。

第1题

原句：We will leave at 9 a.m. if you don't want to go earlier.
转换步骤：

1. 识别结构：从句为"if you don't want..."，符合"if + 主语 + 不定式否定形式"结构。
2. 替换关键词：将"if"替换为"unless"，并去掉否定词"don't"。
3. 调整表达：从句变为"unless you want to go earlier"。
   答案：We will leave at 9 a.m. unless you want to go earlier.

第2题

原句：If extra money cannot be found, the theater will close down.
转换步骤：

1. 识别结构：从句为"if + 主语 + cannot..."，属于否定形式。
2. 替换关键词：将"if"替换为"unless"，并去掉否定词"cannot"。
3. 调整语态：从句变为"unless extra money can be found"。
   答案：Unless extra money can be found, the theater will close down.

第3题

原句：If nothing goes wrong, I'll see you next week.
转换步骤：

1. 识别逻辑：原句意为"如果一切顺利"，等价于"除非出现问题"。
2. 替换关键词：将"if"替换为"unless"，并将"nothing"改为"something"（因"unless"后接肯定形式）。
3. 调整表达：从句变为"unless something goes wrong"。
   答案：Unless something goes wrong, I'll see you next week.
