____________________________________________________________________________．

Answer 1

分析 那就是为什么英语有那么多让人困惑的规则的原因．

解答 答案：That is why English has so many difficult rules that confuse people．
根据要求，可以将why引导的句子变为表语从句，从句需要使用陈述语序，表语从句中保护的定语从句that confuse people不需要发生变化；故答案为That is why English has so many difficult rules that confuse people．

点评 对于句型转换的题目要分析原句的句型结构，并找出同义句型或者相同意思的表达方式，或者使用非谓语动词的形式，或者从句的形式以及一些特殊句式等，要根据句式结构特点进行灵活选择．
