题目

1:" "you are in Shanghai,can you go and see my uncle?A If B While
2：How can you expect to learn anything " " you never listen?A unless B when
可我认为两道题的两个答案意思都符合 请从语法角度说明原因

答案

1 如果你在上海……
当你去到上海时,顺便……
两个对比,第二个更好吧,这时是choose the best one
2 unless=if……not
not是否定,never又是否定
翻译出来是除非你从来不听课,你怎么能学好呢?
你这样不听课,怎么能学好呢?
当然是后者罗~
