Should you break the rule against staring at a stranger on an elevator, you will make the other person exceedingly uncomfortable, and you are likely to feel a bit strange yourself.
【正确答案】正确答案：假如你违背常规，在电梯中盯着一个陌生人，你会令别人极不舒服，而你自己可能也觉得有点不自在。
【答案解析】解析：句子主句：you will make…and you are likely to feel…；从句是省略了if的条件状语从句Should you break the rule…，并导致主谓倒装。
