问题 Cosmic rays of various kinds come through the air from outer space, but enormous quantities of radiation from the sun are ______ off.(2003武汉大学考博试题)
选项 A、avoided
B、excluded
C、screened
D、separated
答案 C
解析 本题意为“宇宙中的各种光线从外层空间通过大气层传来，但是太阳的大量辐射能被大气层隔开”。screen off的意思是“隔开”；avoid的意思是“避免”；exclude的意思是“排除”；separate的意思是“使隔开”，其后不跟off。根据题意，只有C项为正确答案。
