Lesson 56 Future perfect

ポイント
We looked at present and past perfect tenses in that last two lessons, so this week let's look at the 未来完了形 (will have + 過去分詞).

ダイアログ
Kentaro: Carl, is your report finished?
Carl: I'll have finished it by Friday.
Kentaro: Oh! You finished the report last Friday. Why didn't you tell me?

解説
Kentaro hears “finished” and “Friday” and assumes that Carl finished the report last Friday. But Carl used “finished” in a future tense (“I will”), not a past tense. Carl actually means he will finish the report by Friday this week. The 未来完了形 is used to describe actions that will be finished in the future. For example, if you fly to Honolulu this Saturday, you can say “On Sunday, I will have arrived in Honolulu.”
