Explain how you can tell that each sentence is in the future-perfect tense. 7. By the end of the trip, we will have traveled over 1,000 miles. 8. Avery will have competed in ten swimming competitions by the end of the year.

To identify that each sentence is in the future-perfect tense, look for the construction "will have" followed by a past participle verb. In the first example, "will have traveled" indicates an action (traveling) that will be completed before a specified future time (the end of the trip). The second sentence uses the same structure: "will have competed," indicating that Avery's participation in competitions will be completed by the year's end. Future-perfect tense is all about looking forward and reflecting back on actions that will be finished. It sets a deadline – like a time capsule! So, the phrases "by the end" in both sentences signal that these actions are already looking into the future to assert completion. It's a bit like saying, "I’ll be finished with this before that moment arrives!"
