The bac tests a short list of grammar
You do not need every rule in the book. You need these. They come up in the tense and form task, in "circle the option", and they keep your writing correct.
The big one
Past simple, present perfect, past perfect
| Tense | How to build it | Use it for | Time words |
|---|---|---|---|
| Past simple | verb + ed (or V2) | a finished action at a known past time | yesterday, ago, last, in 2019, when |
| Present perfect | have / has + past participle | a past action linked to now, or with no time given | since, for, already, yet, just, ever |
| Past perfect | had + past participle | the first of two past actions | by the time, before, after |
Two structures the bac loves
Passive and conditionals
Passive voice: be + past participle
Use it when we do not know or do not care who does the action. Keep the same tense in the verb "be".
| Active | Passive |
|---|---|
| They build houses. | Houses are built. |
| They cancelled the flight. | The flight was cancelled. |
| They have given 50,000 euros. | 50,000 euros has been given. |
Conditional type 2 (the unreal one)
Example: "If this rule were adopted, it would reduce pollution." With I, he, she, it, use were: "If I were you…". This is also the shape for the personal answer in Reading.
Reported speech and wishes
Reported speech, wish, unless
Reported speech: move one step back
| Direct words | Reported |
|---|---|
| "I am tired," she said. | She said she was tired. |
| "I will help," he said. | He said he would help. |
| "I saw it," she said. | She said she had seen it. |
| questions: use "if" or "whether" and normal word order | He asked if I was ready. |
Wish and unless
- wish + past simple = a wish about now: "I wish I had more time."
- wish + past perfect = a regret about the past: "I wish I had studied harder."
- unless = if not: "You will not pass unless you revise."
Word forms
The "ing" form and word building
Use "ing" after a preposition
After a preposition, the verb takes "ing": "good at writing", "the key to passing", "without looking", "interested in learning".
Word building: change the kind of word
| To make a… | Common endings | Examples |
|---|---|---|
| noun | ness, tion, ment, ity | aware → awareness, explore → exploration, commit → commitment |
| adjective | ful, ous, al, ive, ing | benefit → beneficial, adventure → adventurous, consume → consuming |
| adverb | ly | distinct → distinctly, active → actively |

Now you try. Type the missing or correct word in each box.
Grammar in one line
Time words choose your tense. Use "be + past participle" for the passive. Use "if + past, would + base" for the unreal. Move back for reported speech. Endings change the kind of word. And never drop your "is/are", articles, or the "s" on he/she/it. Now stock your words in Vocabulary.
