should 作为情态动词,可以用在条件状语从句中,表示语气较强的假设,译作“万一”、“竟然”,这时也可将 should 置于从句之首,即将 should 放在主语前面,而省略从属连词 if .例如：
If you should fail to come, ask Mrs Chen to work in your place. （= Should you fail to come, ask Mrs Chen to work in your place. ） 万一你来不了,就叫陈夫人代替你.
If anyone should come, say I am not at home. （= Should anyone come, say I am not at home. ） 万一有人来访,就说我不在家.
If it should rain tomorrow, I wouldn't go. （= Should it rain tomorrow, I wouldn't go.）
万一明天天下雨,我就不去了.
