📖 1. Present tenses and stative verbs

🔑 Key Concepts & Definitions

• Present simple : Present simple is used to describe objective facts, habits, and general truths with the verb in its base form for most subjects.
• Present be + V-ING : Present be + V-ING gives a subjective view and describes actions that are in progress or considered temporary or planned.
• Stative verbs : Stative verbs are verbs that normally do not appear in be + V-ING because they describe states, not actions.

📝 Essential Points

• In present simple negatives and questions, use the auxiliary DO/DOES, and add -s to the main verb only with he, she, it in affirmative statements.
• In present be + V-ING, the verb after BE is in -ing form, and it is used for actions/descriptions now, planned intentions, and annoying repeated behaviour (often with always).
• Do not use be + V-ING with common stative verbs like want, like, belong, know, suppose, remember, need, love, see, realize, mean, forget, prefer, hate, hear, believe, understand, seem, think (e.g., I think, not I’m thinking).

💡 Memory Hook

SIMPLE = facts/habits; BE-ING = “in progress/now”; STATIVES refuse -ing (think, know, like…).

📖 2. Past tenses and perfect aspect

🔑 Key Concepts & Definitions

• Past Simple : Past Simple describes finished, completed actions in the past, often told as the main narration.
• Present perfect : Present perfect links the past to the present and gives a result or ongoing relevance at the moment of speaking.
• Past perfect : Past perfect links two past events, placing one further back than the other to show which happened first.

📝 Essential Points

• Use Past Simple when you have a specific time/date or an ago marker (e.g., yesterday, in 2014, two years ago).
• Use present perfect with time expressions showing an unfinished period (e.g., this year, recently/lately).
• Use present perfect with for + duration and since + starting point to express how long something has been going on.
• Use past perfect after if (unreal) and wish/would rather to show something that did not happen in the past.

💡 Memory Hook

Past Simple = single snap; Present perfect = past→present link; Past perfect = plus-before (the earlier past).

📖 3. Future forms, passive voice and conditionals

🔑 Key Concepts & Definitions

• Passive voice : Passive voice is a sentence form where the grammatical subject is the receiver of the action instead of the doer.
• If conditional types : If conditional types are patterns (Type 0, I, II, III) that match real time, hypothetical present/future, or hypothetical past situations.
• Future will and shall : Will and shall are modal future forms used to express intention, predictions, and (for shall) rule-like obligations, depending on person and context.

📝 Essential Points

• The passive is built with BE (in the required tense) + past participle, and the agent is added with BY only when needed.
• If + Present simple + Present simple expresses a general truth (Type 0), and If + Present simple + WILL + base verb expresses a real possibility (Type I).
• If + past simple + WOULD + base verb expresses an unreal present/future hypothesis (Type II), and If + past perfect + WOULD + have + past participle expresses an unreal past hypothesis (Type III).
• Will is used for predictions and intention, while Shall (especially in official rules/orders and with first person questions/offers) conveys obligation or what is suggested as appropriate.

💡 Memory Hook

Passive: Subject becomes the “THING receiving” (BY marks who did it if you need them). If types: 0 always→I real future→II unreal→III regret past.

📖 4. Modals and past habits

🔑 Key Concepts & Definitions

• Would : Modality form $would+base$ is used for a past, repetitive habit or a characteristic behavior in the past.
• Used to : Structure $used to+base$ describes an action that happened often in the past and no longer happens today.
• Could : Modal $could$ (preterit of $can$) is used for what was possible now with a more “mitigated” sense than $can$ and also for past possibilities or abilities.

📝 Essential Points

• $Would$ expresses a frequentative past habit when the situation is repetitive and the behavior characterizes the subject in the past.
• $Used to+BV$ cannot take a precise date and it suggests a break with the present.
• $Can/Could$ for permission: $could$ is more formal than $can$, and you can also use $may$.

💡 Memory Hook

Past habit: $would$ sounds like “used to (repetition) in stories,” while $used to$ is “the old situation has stopped.”

📖 5. Questions, suggestions and preferences

🔑 Key Concepts & Definitions

• Verbs of taste and preferences : These verbs express liking or dislike and are commonly followed by a gerund ($V$-ing).
• Cannot help + V-ing : This structure is used when you cannot stop yourself from doing something and requires a gerund after it.
• Would like someone to : This preference structure uses “would like” plus an object and an infinitive with to to describe what someone should do.

📝 Essential Points

• The British-style list CAN’T BEAR / CAN’T STAND / ENJOY / FANCY / HATE / LIKE / LOVE / MIND / PREFER is followed by $V$-ing.
• SUGGEST is used with $V$-ing (SUGGEST + $V$-ing) to express an idea for what to do.
• WOULD LIKE / WOULD PREFER follow the pattern WOULD LIKE / WOULD PREFER + object + TO + base verb.

💡 Memory Hook

CAN’T BEAR/STAND/ENJOY = “B E A R” → after these verbs you always hear the -ING sound.

📖 6. Infinitives and gerunds

📖 7. Quantities, pronouns and plurals

🔑 Key Concepts & Definitions

• Regular noun plural : Noun plurals are usually formed by adding -S to the singular form.
• Irregular noun plural : Some nouns change their spelling in the plural in ways that do not follow the normal -S rule.
• Collective groups with verb choice : Group nouns and patterns like the + adjective can trigger either singular or plural verb agreement depending on meaning and form.

📝 Essential Points

• Noun plurals ending in -S, -SH, -CH, -X, -Z or -O take -ES (e.g., watch→watches, church→churches).
• Nouns ending in -Y become -IES in plurals when -Y follows a consonant (party→parties), but just add -S when -Y follows a vowel (boy→boys).
• The plural -S is pronounced [z] after voiced consonants and [s] after voiceless ones (e.g., dogs [z], carts [s]).
• Some nouns never take -S and use a singular verb (e.g., sheep, deer, fish, aircraft, information), while a few always take -S and use a singular verb (e.g., measles, mumps, billiards, physics).

💡 Memory Hook

-ES after S/SH/CH/X/Z/O; consonant+Y → IES; voiced → [z], voiceless → [s].

📊 Synthesis Tables

Present tenses: present simple vs present be + V-ing

If conditionals and regret

⚠️ Common Pitfalls & Confusions

1. Forgetting third-person -S in affirmative present simple (e.g., She swim → She swims).
2. Using present perfect when a specific date or ago marker is present in French “passé composé” (you must use past simple with a date/AGO).
3. Using BE + V-ING with stative verbs like think/know/like (I think, not I’m thinking).
4. Mixing up used to vs would: used to = old action stopped (no precise date), would = past repetitive characteristic behaviour in stories.
5. In if conditionals, using the wrong tense pair (e.g., Type III needs if + past perfect + would have + past participle).
6. Passive voice agent mistakes: using BY only when needed and building passives with BE (tense) + past participle.
7. Confusing pronouns/pronoun forms in relative clauses/questions: in WH- questions with WHAT/WHO as subject, there is no auxiliary inversion (What happened?).

✅ Exam Checklist

1. Conjugate present simple in negatives/questions with DO/DOES and add -S only for he/she/it in affirmative.
2. Choose present be + V-ING for now/temporary/planned intentions and for annoying repetition/behavior, and avoid it with the listed stative verbs.
3. Use past simple for finished actions with specific time/date or -ago markers and apply correct past participle forms only where required by the tense.
4. Use present perfect as a past→present “result/balance” with unfinished periods (this year/recently) and with for + duration / since + starting point.
5. Use past perfect to link two past events and apply it after IF (unreal), wish, and would rather with the correct marker patterns.
6. Select future form: understand when WILL/SHALL are used, when present simple/present be + V-ING can carry future meaning, and how BE GOING TO is chosen.
7. Build the passive correctly with BE (tense) + past participle and add BY only when needed; know got/gotten as an alternative passive pattern (unexpected/change of state).
8. Master if conditional types (0/I/II/III): the if-clause and the matching main-clause structure.
9. Choose modals correctly after basics: modal + base verb (no conjugation of modals), and place negation after the modal.
10. Apply would/used to/get used to correctly: would for past repetitive habit/characteristic, used to for old action stopped (no precise date), be used to for current routine, get used to for becoming accustomed.
11. Form correct questions: direct yes/no with auxiliary inversion and WH- order (except when WHAT/WHO is the subject), and handle indirect questions/tags agreement and polarity.
