Unit 1 — Present Simple vs Present Continuous
Present Simple describes habits and permanent states: «She works every day.» Present Continuous describes actions happening now or temporary situations: «She is working right now.» Key time expressions: always/usually/never (Simple) vs now/at the moment/today (Continuous). Stative verbs (know, believe, love, want) are NOT used in Continuous.
Key concepts:
Present Simple: I play / She plays (habits, routines)
Present Continuous: I am playing (now, temporary)
Stative verbs: know, believe, love, want — NOT used in Continuous
Time expressions Simple: always, usually, every day, never
Time expressions Continuous: now, at the moment, right now, today
Unit 2 — Past Simple — Review
Past Simple describes completed actions at a specific past time. Regular: add -ed (played, watched). Irregular: memorize (go→went, see→saw). Questions: Did + subject + base form. Negatives: didn’t + base form. Time expressions: yesterday, last week, in 2020, ago.
Questions: Did + subject + base form? «Did you play?»
Negatives: didn’t + base form: «She didn’t go»
Time expressions: yesterday, last week/month/year, in 2020, ago
Unit 3 — Past Continuous
Past Continuous (was/were + -ing) describes actions in progress at a specific moment in the past: «I was studying at 8 pm.» Often combined with Past Simple using when/while: «I was reading when the phone rang» (long action interrupted by short action). «While I was cooking, she was cleaning» (two simultaneous actions).
Key concepts:
Form: was/were + verb-ing
When + Past Simple: interruption → «I was sleeping when the alarm rang»
While + Past Continuous: simultaneous → «While I was cooking, she was reading»
Was: I/he/she/it | Were: you/we/they
Negative: wasn’t/weren’t + -ing
Unit 4 — Future: will vs going to
Will for spontaneous decisions, predictions without evidence, promises and offers: «I’ll help you.» Going to for plans already decided and predictions with evidence: «Look at those clouds — it’s going to rain.» Both refer to future but the choice depends on the type of future reference.
Key concepts:
Will: spontaneous decisions, promises, predictions (no evidence)
Going to: plans already made, predictions with evidence
Will: «I’ll help you» (decided now)
Going to: «I’m going to visit Paris» (planned before)
Both: predictions — will (opinion) vs going to (evidence)
Unit 5 — Present Perfect
Present Perfect (have/has + past participle) connects past to present. Uses: experience (I have visited Paris), recent events (She has just arrived), unfinished time (I have studied three hours today). Key words: ever, never, already, yet, just, since, for. Since = point in time (since Monday). For = period of time (for three days).
Key concepts:
Form: have/has + past participle
Ever/Never: experience → «Have you ever been to London?»
Already/Yet: «I have already finished» / «I haven’t finished yet»
Just: very recent → «She has just arrived»
Since (point): since Monday | For (period): for 3 days

As…as for equality: «She is as tall as her brother.» Not as…as for inequality: «He is not as fast as her.» (Not) enough: «old enough to drive» / Too: «too young to vote».
Key concepts:

As…as: equality → «as tall as»
Enough: after adj → «old enough»
Too: before adj → «too young»
Unit 7 — Modal verbs: must, should, have to
Must = personal obligation or strong recommendation: «I must study harder.» Mustn’t = prohibition: «You mustn’t run here.» Should = advice: «You should eat more vegetables.» Shouldn’t = advice against: «You shouldn’t stay up late.» Have to = external obligation: «We have to wear uniform.» Don’t have to = not necessary: «You don’t have to come if you don’t want.»
Key concepts:

Should = advice | Shouldn’t = advice against
Have to = external obligation | Don’t have to = not necessary
Must vs Have to: must=internal, have to=external rules
Mustn’t vs Don’t have to: prohibition vs not necessary

Used for real and possible future situations: «If it rains, I will take an umbrella.» «If you study hard, you will pass the exam.» The if-clause can come first or second: «I will call you if I arrive early.» Never use «will» in the if-clause (WRONG: If it will rain).
Key concepts:
Form: If + Present Simple, will + base form
Real possibility: «If it rains, I will stay home»
If-clause first or second: both correct
NEVER will in the if-clause: ✗ «If it will rain»
Unless = if not: «Unless you study, you will fail»

Unit 9 — Relative clauses
Relative clauses give extra information about a noun. Who for people: «The girl who sits next to me.» Which/That for things: «The book which I read.» Where for places: «The school where I study.» When for times: «The day when we met.» Whose for possession: «The boy whose father is a doctor.»
Key concepts:
Who: people → «The man who called»
Which/That: things → «The car which/that I bought»
Where: places → «The city where I live»
When: times → «The day when we met»
Whose: possession → «The girl whose bag is red»
Unit 10 — Passive voice — Present and Past
Passive voice focuses on the action, not who does it. Form: subject + be + past participle. Present: «English is spoken worldwide.» Past: «The bridge was built in 1900.» By + agent (optional): «The book was written by Cervantes.» Use passive when the agent is unknown, obvious, or unimportant.
Key concepts:
Present passive: is/are + past participle → «English is spoken»
Past passive: was/were + past participle → «It was built in 1900»
By + agent: optional → «written by Cervantes»
Use: when agent is unknown/unimportant
Active → Passive: object becomes subject
Unit 11 — Reported speech — basics
Reported speech reports what someone said without quoting exact words. Tense shift: Present→Past, Past→Past Perfect, will→would, can→could. «I am tired» → She said she was tired. «I will come» → He said he would come. Time/place changes: today→that day, here→there, this→that.
Say vs Tell: say + (that) / tell + person + (that)
Time changes: today→that day, now→then, here→there
Pronoun changes: I→he/she, my→his/her, we→they
Questions: if/whether + statement order (no inversion)
Unit 12 — Vocabulary and Use of English
Vocabulary building strategies: word families (employ→employer→employee→employment), collocations (make a mistake, do homework, take a photo), phrasal verbs (look after, give up, turn on). Reading strategies: predict content from title/images, identify topic sentences, use context clues for unknown words.
Key concepts:
Word families: employ→employer→employee→employment
Collocations: make a mistake, do homework, take a photo
Phrasal verbs: look after (care), give up (stop), turn on (activate)
Context clues: guess meaning from surrounding words
Topic sentence: first sentence of paragraph, states the main idea
