选项
A、attain
B、shed
C、retrieve
D、seek
答案
D
解析
本题要求考生选用恰当的动词。空格所在句子的意思是“要顺利地从一个时区换到另一个时区,就要准确地知道什么时候该——亮光或是避开亮光”。从句子的意思可知,要选用一个与“避开”的意思相反的动词。在4个选项中,D项seek意为“寻求,找寻”,放入句中,与句义吻合,因此是答案。attain的意思是“达到”,shed的意思是“流出流下”,retrieve的意思是“重新得到”或“检索”。这些词都不能与bright light搭配,也不是avoid的反义词,因此都不可能是本题答案。误选这几个面的考生或是还没有掌握seek
