B。once的意思是“一旦”，又如：Once you have taken this decision, there will be no going back, ie you will not be able to change your mind. 一旦作出这个决定，你就不能改变主意。Once you understand this rule, you’ll have no further difficulty. 一旦明白了这条规则，就再也没有困难了。84.

A。unless的意思是“除非”，又如：Don’t call me unless you need help. 除非你需要帮助否则别打电话找我。Unless you change your mind, I won’t be able to help you. 除非你改变你的想法，否则我不能帮助你。87.
