1. Can you wait a few minutes? The boys (not finish) their lunch yet.
- Can you wait a few minutes? The boys have not finished their lunch yet.
Explanation: The sentence is in the present perfect tense. We use the auxiliary verb "have" (in the correct form) plus the past participle of the verb (in this case, "finish") to form the present perfect tense. As the action of finishing the lunch is not yet completed at the present moment, we use the negative form "have not finished".

2. I (feel) dizzy all morning. I think I’ll go to the doctor’s.
- I have been feeling dizzy all morning. I think I'll go to the doctor's.
Explanation: The sentence is in the present perfect continuous tense. We use the auxiliary verb "have" (in the correct form) plus "been" plus the present participle of the verb (in this case, "feeling") to form the present perfect continuous tense. As the action of feeling dizzy began in the past and is still happening at the present moment, we use the present perfect continuous tense.

3. The criminal’s sentence (not decide) until next week.
- The criminal's sentence will not be decided until next week.
Explanation: The sentence is in the future simple passive tense. We use the auxiliary verb "will" (in the correct form) plus "be" plus the past participle of the verb (in this case, "decided") to form the future simple passive tense. As the action of deciding the criminal's sentence will happen in the future, we use the future tense.

4. I (finish) your book by tomorrow, so I’ll give it back to you then.
- I will finish your book by tomorrow, so I'll give it back to you then.
Explanation: The sentence is in the future simple tense. We use the auxiliary verb "will" (in the correct form) plus the base form of the verb (in this case, "finish") to form the future simple tense. As the action of finishing the book will happen in the future, we use the future tense.

5. If I (not see) you before I go, I’ll phone you next week.
- If I don't see you before I go, I'll phone you next week.
Explanation: The sentence is in the first conditional form. We use the base form of the verb (in this case, "see") to talk about a possible future action. As the action of not seeing you is a possibility, we use the present simple tense.
