Future perfect – passive
There are several reasons as to why we use the passive voice in English. In these notes, we’re going to focus on the future perfect in the passive voice and its elaborations. Generally, we use the passive when the focus is on the action and NOT on WHO or WHAT is performing the action.
Construction: will + have + been + past participle (come, enjoyed)
Example verb: look for
|I will have been looked for||We will have been looked for|
|You will have been looked for||You (guys) will have been looked for|
|He/she/it will have been looked for||They will have been looked for|
(1) The subject is unknown, therefore, we don’t know who is the subject.
- Stonehenge will have been visited by at least another thousand visitors by the end of this year.
(2) We use the passive to emphasise the subject.
- The new drug will have been implemented within the pharmaceutical companies by this year.
(3) We use the passive to talk about general truths.
- The speed of light will not have been exceeded by any type of craft at any point in the future.
(4) The passive is used if we want to be unclear or vague about the subject.
- Anti-corruption policies are what will not have been dealt with. (We don’t know which types of policies exactly).
(5) We use the passive when the subject is irrelevant. (We don’t care who or what has caused the action to be).
- Many tourists will have been expected to arrive in Spain and Greece this year and the next. (The focus is on the countries Spain and Greece and not on the tourists).
(6) We use the passive in a more formal atmosphere like a thesis or an important piece of writing, especially scientifically speaking.
- Fossil fuels will have been found lacking in any search conducted by the year 2050.
