[D30] The fact has worried many scientists ____ the earth is becoming warmer
and warmer these years.
A. what B. which
C. that D. though
请翻译,并分析.
答案 C

翻译：地球这些年以来正在变得越来越暖和,这个事实已经使很多科学家忧心忡忡.
解释：此题考查同位语从句的引导词.
1. 主句是The fact has worried many scientists,而后面的从句为同位语从句,修饰主句主语the fact,补充解释它（即该事实）的具体内容.
2. 同位语从句和宾语从句/主语从句/表语从句一样,都属于名词性从句,其引导词也分为三种：
如果从句不缺少任何成分,则用that引导；
如果从句缺少表“是否”之意的疑问,则用whether引导；
如果从句缺少其他成分,则必须根据句意要求选择适当的疑问词进行补充.
3. 该从句the earth is becoming warmer and warmer these years并不缺少任何成分,所以只须用that引导即可；
而A表示从句中缺少表sth（事物）的名词性成分,错误；
which如果引导名词性从句,意思是“哪一个”,句意不通；
though只能引导让步状语从句,而不能引导同位语从句,排除.
