Question

5．她一出现在婚礼上，就吸引了大家的注意．As soon as she appeared at the wedding，she caught everyone's attention．．

Answer 1

分析 As soon as she appeared at the wedding，she caught everyone's attention．

解答 答案：As soon as she appeared at the wedding，she caught everyone's attention．
表达的是过去的事情用一般过去时，表示一…就用as soon as引导的时间状语从句，从句主语she，出现appear，at the wedding在婚礼上，故As soon as she appeared at the wedding，主句引起某人的注意catch one's attention，caught是catch的过去式，故答案是As soon as she appeared at the wedding，she caught everyone's attention．

点评 as soon as 的用法一般是两种情况：
1、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．
注：有时，为了特意表达刚刚完成某事就如何如何，需要用现在完成时．
如：I will go with you as soon as I have washed my face．
2、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
