Sure, let's fill in the blanks with the correct forms of the verbs in either the simple past or the present perfect simple tense.

1. Mother: I want to prepare dinner. **Have you washed** the dishes yet?
2. Daughter: I **washed** the dishes yesterday, but I **haven't had** the time yet to do it today.
3. Mother: **Have you already done** your homework?

Here, the present perfect simple is used to talk about actions that have relevance to the present moment, while the simple past is used for actions that were completed at a specific time in the past.
