问题
We will visit Huangshan next year______we have enough money.
选项
A、lest
B、until
C、unless
D、provided
答案
D
解析
状语从句。provided意为“假若”,相当于if或on condition that,常用于引导条件状语从句。lest意为“以防,以免”,由其引导的从句常常用虚拟语气。until的用法为:如果主句的谓语动词为延续性动词的肯定式,则until意为“直到,到……为止”;如果主句中的谓语动词为非延续性动词,则主句应该用否定式,此时until意为“直到……才”。unless意为“除非,如果不”,相当于if not。
