未来完了形を使ってみよう

The Future Perfect Tense
未来完了形を使って講師と会話してみましょう。
未来完了形はある未来の時点を、それ以前とむすびつけて予測するときに使います。 時点が未来になったというだけで、基本的には現在完了形と考え方は一緒です。 「来月の時点で試験はどうなっているか」について表現ができます。 現在完了形と同じく、「〜したことになる(経験)」、「〜している(継続)」、「〜だろう(結果)」などの使い方ができます。 【回答例】 The exam will have finished by next month. 来月には試験が終わっているぞ

For 20 years! I don't feel I have been spending such a long term with my husband.
Recently I feel that time goes too fast.
By the time till the end of my life, I won't have become fluent in speaking English.

I will have been married for twenty years next month.
For 20 years! I don't feel like I have been spending such a long time with my husband.
Lately, I feel that time goes too fast.
By the the end of my life, I won't have become fluent in speaking English.

Okay, those are good examples. Can you please give me the future perfect tenses in these sentences? What do you mean by "future perfect tenses"?
#miss

It means that an action, a plan or something will have been finished, completed or perfected at some point in the future. For example, I will have submited this estimate by 5 pm. But I won't have gone back to home by 8 pm. By this time next month, I will have been in New Zea land the second with my husband.

But I won't have gone back home until 8 pm. By this time next month, I will have been in New Zealand for the second time with my husband.

I can see that you understand the future perfect tense perfectly now! If there is still something you are unsure about, please ask me.
#miss

I'm really happy to see that.
Could you tell me any other examples of the adverbial phrases?
I know " By this tim..." , "By the end of ..." , and " By the time I'm ..".
Is it Ok to say "I won't have submited this estimate today." and " I will have submited this estimate today." ?
I'd like to practice question sentences, too.

Actually, when using this tense you need to state a specific deadline in the future, and that is why we use "by". So, instead of "today", you could say "by the end of the day". Can you make an example of a question in this tense?
#miss

I should say " I won't have submited this estimate by the end of the day."
Thank you for your advices. Let's try new one. Will you have cleaned our house by the time they come to? Could you tell me whether it needs "will " after "come" or not?

#correct

I should say "I won't have submited this estimate by the end of the day.".
Thank you for your advice. Let's try a new one. Will you have cleaned our house by the time they come? Could you tell me whether it needs "will" after "come" or not?

You are welcome. Your sentence is totally correct, so you don't have to put will after come. After this form " by the time" always goes verb in present simple. Is that ok with you?
#miss

I made a mistake in my question. I should have asked "before" come. You mean "by the time they come to." is correct, aren't you. This grammer topic is very useful. I will have become fluent in English by the time I finish all grammar topics. I am really grateful to you for giving me a lot of useful advice.
