1. so ... that ... 引导结果状语从句2. as soon as引导时间状语从句3. unless引导条件状语从句

【分析】判断状语从句类型需依据引导连词的含义：so...that表“如此……以至于……”，体现动作结果；as soon as表“一……就……”，体现动作发生时间；unless表“除非，如果不”，体现动作条件。据此可识别每个句子的从句类型。
【解析】1. 句中so...that结构用于说明主句“桌子重”导致的结果，引导结果状语从句；2. as soon as用于引导表示“到家后立刻做饭”的时间节点，即时间状语从句；3. unless用于引导表示“不立刻走就会迟到”的前提，即条件状语从句。
【答案】1. so ... that ... 引导结果状语从句
2. as soon as引导时间状语从句
3. unless引导条件状语从句
【知识点】结果状语从句、时间状语从句、条件状语从句
【点评】本题考查初中英语基础语法中常见状语从句引导词的识别，属于基础题型，需牢记不同状语从句引导词的含义与用法。

基础巩固

①C ②unless; stops

【分析】
第①题需辨析各连词含义，结合句意选择合适连词；第②题是同义句转换，需掌握if引导的否定条件句与unless的转换规则。第①题中，句子逻辑为“不能游泳，除非父母陪同”，对应连词含义；第②题中原句是if引导的否定条件句，可转换为unless引导的肯定条件句，需调整动词形式。
【解析】
①题：各选项连词含义：if（如果）、when（当…时）、unless（除非，相当于if not）、until（直到…才）。根据句意“我们不能去游泳，________父母和我们一起”，需表达“除非”的含义，故选C。
②题：原句为“if it doesn't stop raining”，其中if not可替换为unless，因此将否定形式“doesn't stop”改为肯定形式“stops”，故填unless和stops。
【答案】
①C ②unless; stops
【知识点】
连词辨析、条件状语从句、同义句转换
【点评】
本题考查英语基础连词用法及同义转换，属于语法基础题，需掌握常见连词的语义和条件状语从句的转换规则，难度适中。
