问题 They had talked only for a few minute ______ they found they were of different opinions.

选项 A、unless
B、while
C、before
D、once

答案 C

解析 本题考查连词。unless意为“除非”,引导条件状语从句;while引导时间状语从句,主句常用进行时:before引导时间状语从句,意为“在……前”;once引导时间状语从句,意为“一旦”,所以C项为正确答案。【例句】:They had not known each other long before they got married.(他俩认识不久就结婚了。)
