Help the gloomy ghost express his afterlife regrets to the local paranormal investigator. Drag the appropriate verb forms to complete his complaints.
I wish I had chosen to haunt a spooky medieval castle instead of a boring accounting firm.
If only I hadn't scared away the only employee who knew how to make good coffee!
I wish I had chosen to haunt a spooky medieval castle instead of a boring accounting firm.
To talk about regrets regarding past decisions, we use "wish" followed by the past perfect (had chosen).
If only I hadn't scared away the only employee who knew how to make good coffee!
"If only" follows the same rule as "wish" for past regrets. Since the ghost regrets an action he actually did (scaring the employee), he uses the negative past perfect (hadn't scared) to imagine the opposite scenario.
Verb
Verb vs noun vs adjective: nouns name things. Adjectives describe. Verbs express what happens or what IS. The test: can it take tense (walked, will walk)? Can it take -ing? Can it follow to as an infinitive (to walk)? Yes to any → verb. English often converts freely between classes (run = noun or verb), so context decides.
A verb = action/state/occurrence word. 5 forms (base, -s, past, past participle, -ing). Carries tense, aspect, mood, voice. The one required element in every sentence.
Diagnostic: does it change for tense (walk → walked)? Can you put to before it (to walk)? Does it take -ing (walking)? → verb.
Verb mood
Mood vs tense: tense tells you WHEN (past/present/future). Mood tells you the speaker's ATTITUDE (fact/command/hypothetical). She goes (indicative + present) vs Go! (imperative) vs I wish she went (subjunctive + past form but present meaning). Mood and tense work independently.
Verb mood = attitude marking. Indicative (facts), imperative (commands), subjunctive (unreal), conditional (dependent). Each uses different verb forms or auxiliaries.
Diagnostic: is the speaker stating a fact? → indicative. Commanding? → imperative. Imagining something unreal? → subjunctive. Expressing what would happen under a condition? → conditional.
Subjunctive mood
Subjunctive vs indicative: indicative states facts (He goes every day). Subjunctive marks unreality (I suggest he go; If I were you). The subjunctive drops the -s and insists on were — signalling "this isn't (or may not be) real." In informal speech it's disappearing, but formal/academic writing still expects it.
The subjunctive mood = hypothetical/counterfactual marker. Present subjunctive (base form after suggest/demand/insist that). Past subjunctive (were in unreal conditionals).
Diagnostic: is the clause about something unreal, demanded, or recommended (not yet true)? → subjunctive. Is it factual? → indicative.
Perfect tense
Present perfect vs simple past: I lost my keys (past: specific time, done). I have lost my keys (perfect: result matters NOW — I still don't have them). The perfect always connects past action to present relevance. If the time is specified (yesterday, in 2010) → simple past. If the result matters now → present perfect.
The perfect aspect = have + past participle. Marks completion relative to a time point. Three forms: present/past/future perfect.
Diagnostic: does the sentence mention a specific finished time (yesterday, last year, in 1999)? → simple past. Is it about the result/relevance NOW? → present perfect.
Past tense
Simple past vs past perfect: simple past puts events on the main timeline (I arrived. She left.). Past perfect marks an event as earlier than another past event (She had left before I arrived). If all events are in sequence, simple past is enough. Only use past perfect when you need to show "earlier than the main story."
The past tense has four forms encoding different temporal relationships: simple past, past progressive, past perfect, past perfect progressive.
Diagnostic: are events in sequence? → simple past is fine. Need to show one event happened before another past event? → past perfect for the earlier one.
B1 | Intermediate
B1 vs B2: B1 handles standard everyday communication and simple opinions. B2 handles abstract topics, sustained arguments, and nuanced register. If you can chat about your life but struggle to debate an issue or write a formal essay, you're B1.
B1 is the intermediate CEFR level: independent handling of familiar topics, second conditional, basic passive, reported speech, and linking words for cause and contrast.
Diagnostic: can you read a newspaper article on a familiar topic and summarise the argument? Comfortably → B2. Struggle with abstractions → still B1.
Medium
Medium vs Easy: Easy has one obviously correct answer and clearly wrong distractors. Medium has one correct answer but plausible distractors — you need to actually know the rule, not just guess from sound.
The Medium tag filters for A2–B1 challenges with realistic difficulty: one rule per question, plausible alternatives, everyday contexts.
Diagnostic: if you're scoring 90%+ on Easy, move here. If you're below 60% on Medium, go back to Easy for that topic. Target 70–80% accuracy for maximum learning.
