Answer 1

1 We had been waiting here until he plugged in the laptop.  (we need Past Perfect to show the earlier action)

2 I forbid you to use the computer till you are sixteen.  (we use Present Simple in time clauses that refer to future time)

3 When Sophia comes back next month, it will have been three years since she is away.  (we use Future Perfect in the main clause to talk about an action that will finish before a certain point in the future)

4 Scientists had found it difficult to cure many illnesses until the level of technology was improved.  (we use Past Perfect to show the earlier action)

5 She never uses her mobile when the battery is low.  (we use Present Simple to describe a habit, a regular action)

6 Last week, Sam required a refund when he discovered that his new digital camera was broken.  (we use Past Simple to talk about things that happened in the past)

7 Until you bought me a cellular, I had used a land-line phone.  (we use Past Perfect for the action that took place first)

8 Tomorrow Tom will pay the connection fee when he goes to work​. (we use Future Simple in the main clause - because it refers to the future -and Present Simple in the time clause)

Answer 2

1. We will be waiting here until he plugs in the laptop. Explanation: The verb "plug" should be in the present tense ("plugs") because it refers to a future action.

2. I forbid you to use the computer until you are sixteen. Explanation: The word "till" should be replaced with "until." Additionally, the verb "have been" should be changed to "are" to maintain consistency in the verb tense.

3. When Sophia comes back next month, it will have been three years since she was away. Explanation: The phrase "it is" should be replaced with "it will have been" to indicate a future perfect tense, which describes an action completed before a specific time in the future.

4. Scientists find it difficult to cure many illnesses until the level of technology has been improved. Explanation: The word "till" should be replaced with "until." The verb tense "was" should be changed to "has been" to indicate a past action that has a present relevance.

5. She never uses her mobile when the battery is low. Explanation: The verb "had been" should be replaced with the present tense "is" since it refers to a general condition in the present.

6. Last week, Sam requested a refund when he discovered that his new digital camera is broken. Explanation: The verb "requires" should be changed to the past tense "requested" to match the past tense of "discovers." Additionally, "Last week" indicates a specific time in the past, so the present tense verb should be changed to past tense.

7. Before you bought me a cellular, I used a land-line phone. Explanation: The word "until" should be replaced with "before" to indicate the sequence of events.

8. Tomorrow Tom will pay the connection fee when he goes to work. Explanation: The verb "pay" should be changed to future tense "will pay" to indicate an action that will happen in the future. The verb "go" should be changed to "goes" to maintain consistency in verb tense.
