Future Perfect — English Bac Éco

In the Bac Éco stream, where English is coefficient 2, the Language section rewards precise grammar with quick marks. “By 8 pm, we will have finished dinner”: the future perfect announces that an action will be complete before a specific point in the future, often introduced by by.

English has a coefficient of 2 in the Bac Sciences Économiques stream, the same weight as Philosophy and Law. It sits behind the professional subjects (General Economics and Accounting, coefficient 6; Business Organisation, coefficient 3; Applied Mathematics, coefficient 4). The stream's grounding in institutions and collective behaviour makes the English themes on citizenship, organisations and development familiar ground.

في الامتحان

Three parts: Reading Comprehension, Language, and Writing (about 180 words). Economics candidates are used to analysing collective phenomena and institutions, which helps on essay prompts about international organisations, brain drain or sustainable development — provided the answer stays in plain English, not economics jargon.

أهداف التعلم

  • Apply this grammar point accurately in the Language section and in the guided writing of the Bac Éco English exam (coefficient 2)
  • Form the future perfect: will have + past participle; negative won't have
  • Identify a precise future reference point (by + date / time, by the time + present)
  • Distinguish the future perfect (an action completed before a future point) from the simple future (a future action with no earlier reference)
  • Use the present simple, never will, in the clause introduced by by the time

المفاهيم الأساسية

Form

will have + past participle. Negative: won't have + past participle. Question: Will + subject + have + past participle?

Use: an action completed before a future point

The future perfect announces that an action will be finished before a specific future moment, introduced by by + date / time (“by 2030”) or by the time + a present-tense clause (“by the time you arrive”).

The by the time clause trap

In the clause introduced by by the time, use the present simple, never will, even though the meaning is future — as in all English time clauses (if, when, before, after, as soon as).

الأخطاء الشائعة

1

Forgetting have after will: “will finished” is wrong — use “will have finished”.

2

Using will in the by the time clause: use the present simple (“by the time the guests arrive”, not “will arrive”).

3

Confusing the future perfect (an action completed before a future point) with the simple future (an action that will happen, with no sense of earlier completion).

مثال محلول

نص السؤال

Put the verb in brackets into the right tense: “By 8 pm, we (finish) dinner.”

التصحيح

Spot the future reference. “By 8 pm” is a precise future moment before which an action must be complete.
Choose the tense. This is the typical future perfect structure: will have + past participle.
Result. “By 8 pm, we will have finished dinner.”

3 تمارين للتدرب

التمرين 1

Easy
Complete: “By next year, she (graduate) from university.”
عرض التصحيح
“will have graduated” — an action completed before a future point (next year).

التمرين 2

Medium
Rewrite with by the time: “The train leaves at 6 pm. I will arrive at 6:15 pm.”
عرض التصحيح
“By the time I arrive, the train will have left.” — the train leaving comes before my future arrival; the by the time clause is in the present simple (arrive), the main clause in the future perfect (will have left).

التمرين 3

Hard
Correct: “By the time you will read this letter, I will have leave the country.”
عرض التصحيح
Two errors: the by the time clause must be present simple (read, not will read), and the main verb must be a past participle (will have LEFT, not leave). Corrected: “By the time you read this letter, I will have left the country.”

الأسئلة الشائعة

Is the future perfect common in the national exam?

Less common than the past perfect or the passive, but it appears regularly in the Language section's tense exercises, usually paired with by or by the time to test recognition of the future reference point.

Can I use will in a time clause?

No, never: after if, when, before, after, as soon as and by the time, use the present simple even for future meaning. Will stays in the main clause.

What is the difference between future perfect simple and continuous?

The future perfect simple (will have + past participle) stresses the completed result; the future perfect continuous (will have been + verb-ing) would stress the duration up to the future point. Only the simple is on the Bac programme.

How do I fit English revision around the economics and accounting subjects?

A short weekly session: one chapter (rule or word list, two examples), then a short paragraph. Focus especially on the society themes — citizenship, international organisations, development — which are close to your other subjects, and keep a model introduction and conclusion ready. A mark above your average is within reach.

Is this grammar point actually tested on the Bac Éco English paper?

Yes — in the Language section as gap-fill, sentence-joining or error-correction, and indirectly in Writing, where the same structures decide whether a sentence is marked as accurate. One rule, two examples and one typical mistake per point is enough to cover both.
