it is important that I-----to Mr williams immediately A speak B spoke C willspeak Dto speak

Question

要求有完整解释

Answer 1

A.speak
It is important ( necessary, right, strange, natural...) that ...

由于主句中的形容词不同，that 后的从句中要用虚拟语气（should + 动词原形），should 可以省去。

例如：It is important that we (should) learn English well.追问

意思是 It is important ( necessary, right, strange, natural...) that这个结构后的句子就要用虚拟语气吗

追答

是的哦。
