The correct answers are It's high time you bought an alarm clock! and I'd rather you didn't arrive late every single day.
Both "It's high time" and "I'd rather" (when referring to another person) require a subject and a verb in the past simple to talk about present or future situations.
- It's high time you bought: The unreal past emphasizes that buying an alarm clock is long overdue.
- I'd rather you didn't arrive: The unreal past expresses a strong preference about the employee's current behavior.
Subjunctive mood
- ✅ If I were you… — past subjunctive (not was)
- ✅ I suggest that he go. — present subjunctive (not goes)
- ✅ It's important that she be present. — present subjunctive
- ❌ If I was you… — common in speech, avoided in formal writing
The subjunctive uses bare-infinitive forms (go, be) after verbs of demand/suggestion, and were (not was) in unreal/hypothetical conditions. Two contexts: that-clauses (I insist that he leave) and if-clauses (If she were here).
Rule: after suggest/recommend/demand/insist that… → use base form. In if + unreal condition → use were for all persons.
Past tense
- I walked home. — simple past (completed action)
- I was walking when it rained. — past progressive (in progress)
- I had already left when she arrived. — past perfect (earlier past)
- I had been waiting for an hour. — past perfect progressive (duration up to a past point)
Four past tense forms: simple past (done), past progressive (was happening), past perfect (had already happened), past perfect progressive (had been happening). Each encodes different timing relative to other past events.
Pattern: simple past = the story's main timeline. Past progressive = background action. Past perfect = flashback to something even earlier.
Verb mood
- Indicative: She goes every day. — stating fact
- Imperative: Go now. — giving command
- Subjunctive: I suggest she go. — hypothetical/recommendation
- Conditional: She would go if asked. — dependent on condition
Verb mood marks the speaker's attitude: indicative (fact), imperative (command), subjunctive (unreal/recommended), conditional (would/could). English barely marks mood morphologically — mostly through auxiliaries and word order.
Rule: stating a fact? → indicative. Giving a command? → imperative. Imagining/recommending? → subjunctive or conditional. The mood determines which verb forms and auxiliaries you use.
Simple tense
- ✅ I go to work every day. — present simple (habit)
- ✅ She went home yesterday. — past simple (completed action)
- ✅ I will call you later. — future simple (promise/decision)
- ✅ Water boils at 100°C. — present simple (general truth)
The simple aspect is the default, unmarked verb form. Present simple = habits, facts, schedules. Past simple = completed actions. Future simple = predictions, promises, decisions. No auxiliary needed (except will for future and do for questions/negatives).
Rule: if the action is a fact, habit, completed event, or scheduled future — and you don't need to emphasise it being in-progress or connected to now → simple tense.
Verb
- walk → walk / walks / walked / walked / walking (5 forms, regular)
- go → go / goes / went / gone / going (5 forms, irregular)
- be → am/is/are/was/were/be/being/been (8 forms)
- can → can / could (modal: only 2 forms, no -s, no -ing)
A verb is the one word class every English sentence requires. Carries tense (when), aspect (duration), mood (attitude), and voice (active/passive). Regular verbs add -ed; ~200 irregular verbs have unpredictable past forms.
Key insight: fix your verbs and most grammar problems disappear. Wrong tense, wrong agreement, wrong form — verb errors account for the majority of grammatical mistakes.
B1 | Intermediate
- ✅ If I had more time, I would travel more. — second conditional
- ✅ The bridge was built in 1920. — passive voice
- ✅ She said she was tired. — reported speech with backshift
- ✅ Although it rained, we enjoyed the trip. — complex sentence with concession
These are B1 patterns — the CEFR intermediate level. At B1 you link ideas, use passive voice, handle reported speech, and manage second conditional — enough for travel, work basics, and everyday independence.
Marker: if you can explain why something happened and follow a news story, you're B1.
Medium
- If I were you, I would apologise. — one rule (second conditional), but distractors like was tempt you
- Answers require active thought, not instant pattern recognition
- Vocabulary and context are realistic, not artificially simplified
- Usually tests one rule, but the wrong answers are plausible
Medium marks middle-difficulty challenges: A2–B1, one rule tested, but with realistic distractors that require genuine understanding.
Use "Medium" when Easy feels too obvious but Hard feels overwhelming. This is where most productive learning happens — the sweet spot of difficulty.
