Future Perfect or Future Perfect Continuous

1. He will have built / will have been building the house by next summer. - The correct form in this sentence is "He will have built the house by next summer". - The Future Perfect tense is used to express an action that will be completed before a specific time in the future. - The Future Perfect Continuous tense is not used with stative verbs, and "build" is not a stative verb [[1]](https://fsc.bsu.by/wp-content/uploads/2015/12/Prakticheskaya-grammatika-1-kurs-English-Grammar-Practice-uchebno-metodicheskoe-posobie.pdf).

2. She will have typed / will have been typing the documents for two hours by 4 o'clock. - The correct form in this sentence is "She will have typed the documents for two hours by 4 o'clock". - The Future Perfect tense is used to express an action that will be completed before a specific time in the future. - The Future Perfect Continuous tense is not used in this sentence because it implies continuous action over a period of time, but the sentence specifies a duration of two hours [[1]](https://fsc.bsu.by/wp-content/uploads/2015/12/Prakticheskaya-grammatika-1-kurs-English-Grammar-Practice-uchebno-metodicheskoe-posobie.pdf).

3.

4. They will have climbed / will have been climbing Everest for a week by next Wednesday. - The correct form in this sentence is "They will have climbed Everest for a week by next Wednesday". - The Future Perfect tense is used to express an action that will be completed before a specific time in the future. - The Future Perfect Continuous tense is not used in this sentence because it implies continuous action over a period of time, but the sentence specifies completion of the action (climbing Everest for a week) by next Wednesday [[1]](https://fsc.bsu.by/wp-content/uploads/2015/12/Prakticheskaya-grammatika-1-kurs-English-Grammar-Practice-uchebno-metodicheskoe-posobie.pdf).

5. They will have climbed / will have been climbing Everest by next Sunday. - Both forms are correct in this sentence: "They will have climbed Everest by next Sunday" and "They will have been climbing Everest by next Sunday". - The Future Perfect tense is used to express an action that will be completed before a specific time in the future. - The Future Perfect Continuous tense is used to express continuous action over a period of time leading up to a specific time in the future. - Both forms convey a similar meaning, but the continuous form emphasizes the ongoing nature of the action [[1]](https://fsc.bsu.by/wp-content/uploads/2015/12/Prakticheskaya-grammatika-1-kurs-English-Grammar-Practice-uchebno-metodicheskoe-posobie.pdf).
