​already与yet区别

already与yet区别

already [ˌɔlˈrɛdi]副词，已经

The concert has already been on for 15minutes. 音乐会已经进行15分钟了。

【辨析】already与yet

already表示“已经”，yet还，已经，仍然。两者可用于现在完成时态，例：

I have already finished my lunch.

Have you seen Tom yet?

They haven't visited Rome yet.

小结

already

①用来指发生于说话之前的事件。但是，它指代的是对现在产生影响的事件。

因此要用现在完成时态。

②句中位置：主语+have/has+already+过去分词+宾语，例

I have already seen that film.

③一般用于肯定句中。

yet

①用于确认某事目前有没有发生。这种用法与现在完成时态中关于ever的疑问句类似：

Have you ever seen that film?

Have you seen that film yet?

你看过那个电影吗？

②这些问句在意义上十分相似，但是yet一般用于询问不久前发生的某件事。Yet常用于某人期望最近发生某事。

③句中位置：have+主语+过去分词+宾语+yet？

Have you finished that report yet?

④一般用于否定句和疑问句。
