I'll let you know as soon as he ——A arrives B will arrive C arrived D has arrived
为什么

I'll let you know as soon as he ——A arrives B will arrive C arrived D has arrived为什么
选 A arrives
他一到我就通知你
在时间状语从句中,主句用一般将来时,从句用一般现在时.
as soon as 一……就……,引导的就是时间状语从句；
所以选 A
保证准确率~

正确答案是A

arrives 为什么我还真说不清楚，经验+语感，时间状语从句大都是一般时态吧

选第一个. know 既可以做及物动词又可以做不及物动词， 所以这应该是时间状语从句，而不是宾语从句。
