ever作为非肯定词，通常用在疑问句和否定句中，表示at any time之意。此时ever为中位状语，即用于主语后，实意动词前，如果谓语含有操作词，则位于操作词之后。例如：

What has ever made you afraid?

No one has ever seen a better example of woodwork.

Did it ever occur to you that I might like more myself?

Has this ever been done before?

ever 也用于修饰最高级的定语从句中，例如：

That was the worst movie that had ever been made.

这个句子可以省略定语从句，只保留ever作后置定语：

That was the worst movie ever.

That was my best vacation ever.

= That was the best vacation I have ever had.

网友的二个句子属于不同类型，第一句为疑问句，ever要用作中位状语， 不能放在句末。第二句为ever后置修饰最高级，不可以移至中位状语位置。
