题目解答
答案
A选项"如果";C选项"一旦";D选项"当…时候";B选项"如果不;除非"; unless=if…not,句中"unless fully covered"为"连词+省略结构",补充完整为"unless you are fully covered"可转换成"If you aren't fully covered"理解,根据句意及逻辑关系"外面非常冷"可推知"如果不裹一件厚实点的衣服会很冷."B项符合语境.
故选:B。
故选:B。
解析
步骤 1:理解句子结构
句子的结构是 "It is so cold that you can't go outside __________ fully covered in thick clothes.",其中 "It is so cold" 是主句,"that you can't go outside" 是结果状语从句,空格处需要填入一个连词,使得句子逻辑通顺。
步骤 2:分析选项
A. if:如果
B. unless:除非
C. once:一旦
D. when:当...时候
步骤 3:选择合适的连词
根据句子的意思,"外面非常冷",所以"除非你裹上厚衣服,否则你不能出去"。因此,"unless" 符合句子的逻辑关系,可以转换成 "if you are not fully covered in thick clothes"。
