as soon as连接的时间状语从句中，指未发生的动作，规律是：主句一般将来时，从句用一般现在时代替一般将来时
如：I will tell him the news as soon as he comes back。
指紧接着发生的两个短动作，主从句都用一般过去时
如 He took out his English books as soon as he sat down
就这两种情况 ，熟记就行。
在宾语从句中，当主句为与过去时的时候，从句必须用与主句相对应的时态，所以为了与主句动词said呼应，时间状语从句中的will look up应该对应为过去将来时态would look up，finds对应为found本回答被提问者采纳
eg:As soon as you arrived ,the thing will be all right.
