I wonder if it’s because I haven’t been able to be outdoors for so long that I’ve grown crazy about everything to do with nature.
我剖析的状况是 ：If 引导宾从，Because引导缘由状语从句，So…that…结果状语从句？
我看分析是 it is···that···是强调句型，那也就是 so that 这里不可以算是引导结果状从？那把这个强调it is···that··去掉,可If beacause...这种两个关系词放一块么；还有 去掉that 后 so long I have 之间是否需要逗号隔开了。
应如此剖析：
I（主语） wonder （谓语）if it’s because I haven’t been able to be outdoors for so long that I’ve grown crazy about everything to do with nature.（宾语从句）
在if 宾语从句中，又包括一个带有缘由状语从句的复合句，而且这个复合句中是什么原因从句被强调。还原后宾语从句为：
if I’ve grown crazy about everything to do with nature because I haven’t been able to be outdoors for so long.
整个句子还原后是：
I wonder if I’ve grown crazy about everything to do with naturebecause I haven’t been able to be outdoors for so long.
