问题
It is essential that people______enough vitamins every day.
选项
A、have
B、had
C、must have
D、will have
答案
A
解析
本题考查虚拟语气的用法。这是虚拟语气的特殊用法。it is+essential等形容词后由that引导的主语从句中需要使用虚拟语气,动词形式为(should)+动词原形,should通常可以省略。这类形容词还包括necessary,important,essential,imperative,urgent,preferable,vital,advisable等。所以选项A为正确答案。
