"We have finished the dessert."

Translation: 我们已经吃完了甜点。

[daltonstout59]

The english translation doesn't include "already", so “已经” shouldn't be required.

[Etiennera]

This is right.

Could the 了 be at the end of the sentence

[Rebecca495786]

I've personally always used 了 at the end of sentences but it could be a regional thing.

Shouldn't this also accept "我们吃完了甜点"?
