1.A
此题experience是及物动词,所以其后加的rain是不可数名词,而不是动词.
楼主对倍数句型不太明白：
倍数词(twice) + as + 形容词原级(much) + 名词(rain) + as ...
即形容词much是修饰名词rain的,不能把rain放到much前面去.
再如：I earn twice as much money as you.我赚你两倍多的钱.
2.A
这里think of的宾语不是getting enough money,而是先行词the way；
而to get enough money是the way的后置定语,构成固定短语：the way to do sth = the way of doing sth “做某事的方法”.
3.B
paper-making是一个单词,意思是“造纸的”；而paper-made这个单词是没有的；
复合形容词不一定是按照所谓被动/主动关系来构成的.
比如：English-speaking“说英语的”.按照楼主的观点,English不也是被“speak”的,岂不是要改成English-spoken了?
