Will have意思

"Will have" is a modal verb construction that is used to talk about future actions or events that are expected to happen or that have been arranged. It is often used with the first person (I, we) to express intentions or plans, and with the second or third person to make predictions or assumptions about their future actions.

Here are some examples of how "will have" is used:

1. Future Plans:

   • I will have finished my homework by the time you get home.
   • We will have started the project by next week.

2. Future Assumptions:

   • By the time he graduates, he will have learned a lot.
   • They will have left before we arrive.

3. Future Actions:

   • I'm going to the gym, so I will have exercised today.
   • Before the meeting, I will have prepared my presentation.

4. Future Schedules:

   • The train will have arrived by 7:00 a.m.
   • The movie will have started by the time we get there.

5. Future Possibilities:

   • If you don't stop, you will have caused a lot of trouble.
   • By the end of the year, we might have found a solution.

It's important to note that "will have" is used for actions that will be completed before a certain point in the future, not for ongoing actions that will continue into the future. For ongoing actions, you would use "will be" instead.
