Space is a dangerous place, not only because of meteors (流星) but also because of rays from the sun and other stars. The atmosphere again acts 【C1】______ our protective blanket on 【C2】______ .

选项
A、what
B、which
C、that
D、why
答案
C
解析
逻辑衔接题,该从句并不缺少句子成分,故排除what 和which;语法上看why 和that 都可以,这就要从意思及逻辑上判断,此句和下一句间用的是分号,分析它们之间的关系,下句中有60 rems,而之前有提到100 millirems 再看本句,不难发现far more radiation ______ this 正是这两个数字的比较,也就是分号后的句子只是对分号前信息的进一步说明即为什么是 far more,而不是讲have reason to think 的原因,故选C
