We all know the truth _____ there are air, water and sunlight, there are living things.
A、in wherever
B、that where
C、where
D、that
【正确答案】：B
【题目解析】：本题考查名词性从句中引导词的运用．题干空格后面说明the truth内容的同位语从句；从句中又出现了地点状语从句；"where there are air，water and sunlight there are living things．"从意思到成分都完整；that引导名词性从句时在从句中不担任成分又没有意义；引导同位语从句的that不可省略；故选B．
