His sister has already piad for the camera.(改为一般疑问句）
_____ ____ sister piad for the camera_______,

答案上最后一个空是yet，可我不知道为什么，大虾们讲讲~~

这句话应该是 Has his sister paid for the camera yet?

因为一般疑问句都是要 yet 结尾的
表示已经做过某事的标志是 already 和 yet
already是在陈述句中使用

如: I have paid for the camera already.

yet是在疑问句和否定句中使用

如: I haven't paid for the camera yet.

Have you paid for the camera yet?

这是固定用法，记住就可以了。
祝学习愉快。
