都…了，还…【dōu … le, hái …】

都…了 says a point has already been reached – a time, an age, an amount. 还 in the next clause says something that should have changed by then still hasn't. Together they make a complaint, a rebuke or surprise.

Here 都 means "already", not "all", and it is unstressed. Plain 已经…了 states the same fact with no complaint in it; 都 adds the speaker's impatience.

Often a question

The second clause is often a question, but it isn't asking anything. It means "you shouldn't".

The 了 stays

The first clause needs its 了. Without it, 都 reads as "all", and the sentence falls apart.

• × 都十点，你还不起床？ → 都十点了，你还不起床？
• × 都十点了，你也不起床？ → 都十点了，你还不起床？

The second line swaps 还 for 也. 也 means "also", and there is nothing here to be "also".
