求解答英语选择It's essential ___ everyone ______ what to do.为什么是that...know而不是that...knows
求解答英语选择It's essential ___ everyone ______ what to do.
为什么是that...know而不是that...knows
求解答英语选择It's essential ___ everyone ______ what to do.为什么是that...know而不是that...knows
因为在此句型中后面的that 引导的主语从句中一般用虚拟语气（should)+ 动词原形.should 可以省略,should 一省略,不就是【动词原形】了?：）
It's essential 【that】everyone 【（should) know】 what to do.
哦
因为EVeryone 是单数，动词加'S.
这个是一个句型呀
It's essential that sb. (should) do sth
