Step-by-step explanation:
Understanding the Future Perfect Continuous Tense
The Future Perfect Continuous Tense is an aspect of verb tense that is used to describe an action that will have started in the past or the present and is expected to continue into the future, up until a specific point in time. This tense is constructed with the formula 'will have been' followed by the verb's present participle (V-ing). For example, in the sentence 'By 2025, she will have been working at the company for 10 years,' the action of working began in the past and is expected to continue up until the year 2025.
Using the correct verb tense is crucial for clear communication. Writers often shift between tenses to convey different time periods within a narrative. When telling a story, using verb tense consistency is important to maintain clarity, although shifts may be used deliberately to show changes in time. In literature and humanities, the present tense or present perfect tense are often used, whereas in the social and natural sciences, as well as technical fields, the past tense or present perfect tense are more common
It is essential to understand the differences between tenses like the simple past (e.g. 'bought') and the present perfect (e.g. 'has bought') to ensure accurate communication of time in writing. Incorrect usage of tenses can lead to confusion about the timeline of events.
