(4)lest/for fear that/in case 從句謂語用(should+)動(dòng)詞原形。如：
The mad man was put in the soft-padded cell lest he injure himself.
(5)whether…or…有時(shí)謂語用be的原形，引導(dǎo)讓步虛擬從句，這種用法經(jīng)常采用倒裝結(jié)構(gòu)。如：
Church as we use the word refers to all religious institutions, be they Christian, Islamic, Buddhist, Jewish, and so on.
The business of each day, be it selling goods or shipping them, went quite smoothly.
