Answer 1

第一个选B 记住一个永远的法则，倍数永远在最前面，排除D energy 是不可数名词，as much as 是固定短语，排除A C
第二个选C 根据题意是人类活动导致全球变暖，而不是全球变暖引起人类活动，排除A，B ，人类活动是一个整体，不可数名词，故C
第三个选A 意思是如果这样 B 如有曾经如何 c搭配错误，不能单独用，后面要跟句子两成整体 D如果有一些的话
望楼主采纳！

Answer 2

1.B
倍数 as many 可数n./much 不可数n. 固定搭配，表示倍数的
2.C
It is ... that是强调句，后面的单词的形式由is 后面单词的单复数形式决定。本句为“人类的活动导致了全球变暖。”所以选C
3.A
if so 固定短语“假如这样的话”

希望对楼主有帮助，呵呵。
