Scientists generally agree that Earth"s climate will warm up over the next 50 to 100 years ________ it has warmed in the 20,000 years since Ice Age.
A. so long as
B. as much as
C. as long as
D. as well as
题目解答
答案
B. as much as
解析
本题考查比较状语从句的连接词选择，核心在于理解句子中比较的对象是程度而非时间或条件。关键点在于区分选项中短语的用法：
- as much as 表示“与...一样多/程度”，用于比较程度；
- as long as 既可表示“只要”（条件），也可表示“与...一样长”（时间/长度）；
- so long as 仅表示“只要”（条件）；
- as well as 表示“也，和...一样好”，常用于列举。
句子需表达“未来变暖程度与过去2万年相当”，比较对象是变暖的程度，而非时间或条件。
选项分析：
- A. so long as：表示条件（如“只要”），与题意不符；
- B. as much as：表示“与...程度相同”，符合比较“变暖程度”的需求；
- C. as long as：若强调时间长度，但句中比较的是“变暖程度”，非时间；
- D. as well as：表示“也”，通常用于并列，与句意无关。
