Correct the mistakes. 1. I wish I would go home now. 2. If I were you , I will ask my father's advice 3. Unless you don’t ask her , she won’t come. 4. I wish you will listen to me 5. I wish I saw the play when it was on at the theatre 6. I wish I will go on long holidays to hot places. 7. If I will have time , I will tidy up before I go out .

Sure, here is the corrected version of the sentences:

1. I wish I could go home now.
In this sentence, we use "could" instead of "would" to express a hypothetical or unreal situation. "Would" is used to talk about past habits, but in this case, we are talking about a current desire to go home.

2. If I were you, I would ask my father's advice.
We use "were" instead of "am" or "will" to show a hypothetical or unreal condition. "Would" is used in the second clause to indicate a possible outcome.

3. Unless you ask her, she won't come.
In this sentence, we remove the negative word "don't" from the condition. "Unless" already implies a negative meaning, so using "don't" is redundant.

4. I wish you would listen to me.
We use "would" to express a wish or desire for someone else's actions. By using "would," we indicate that we want the person to listen to us in the future.

5. I wish I had seen the play when it was on at the theatre.
Here, we use "had seen" instead of "saw" because we are talking about a missed opportunity in the past. "Had seen" is the past perfect tense, which is used to talk about an action completed before another past action.

6. I wish I could go on long holidays to hot places.
Again, we use "could" instead of "will" to express a hypothetical or unreal possibility. By using "could," we indicate a desire but acknowledge that it may not happen.

7. If I have time, I will tidy up before I go out.
We use the present simple tense in the first clause because it's a general statement about a possible future event. "Will" is used in the second clause to indicate a probable action to be taken if the condition is fulfilled.

I hope this explanation and the step-by-step corrections make it clear to you. Let me know if you have any further questions!
