老师你好，as soon as 表示“1、..就...”引导时间状语从句，假如从句表示以后发生的动作，则用通常目前时，而主句用通常以后时。即，主将从现。我遇见一句话，是如此写的：
As soon as he opens the gate from the outside, he comes into the garden and waits until the gate shuts.
这句说中，从句用的通常目前时，而主句并没用通常以后时，是为何呢？
难道说 as soon as 引导的从句用通常目前时也并不是肯定是表示以后吗？
盼复，感谢！
时间状语从句用通常目前时的时候，主句的时态依据不一样的需要和语境可以有多种可能：
1. 主句用通常以后时。如：
I’ll tell him as soon as I see him. 我一见到他就告诉他。
We’ll go just as soon as this weather lets up. 天气一好转，大家就出发。
We shall let you know as soon as there’s any news. 一有消息，大家就对你说。
2. 主句用通常目前时。如：
I pay my money into the bank as soon as I get paid. 一发薪资我就把钱存入银行。
3. 主句含有情态动词。如：
You must ask him to call me as soon as he comes in. 他一来你就需要让他给我打电话。
4. 主句为祈使句。如：
Don’t forget to cable us as soon as you arrive. 别忘了一到就给大家打个电报。
