Complete the detective's frustrating interview by selecting the correct phrase for each gap.
The detective sighed, rubbing his temples. "Let's try this again. Can you explain how _______________________________________?"
The witness shrugged, sipping his coffee. "I'm not sure. I also don't know where _________________________ after the basketball game ended."

"Can you explain how the giant chicken escaped?" "I also don't know where he went after the basketball game ended."

In indirect questions in the simple past tense, we do not use the auxiliary verb "did".

Instead, we use the standard affirmative past tense form of the verb (Subject + Past Tense Verb).

Direct: "How did the chicken escape?"

Indirect: "Can you explain how the chicken escaped?"

Questions

  • Do you like coffee? — do-support (no existing auxiliary)
  • Can she swim? — inversion (auxiliary before subject)
  • Where does he live? — wh-question
  • You're coming, aren't you? — tag question

Questions require inversion (auxiliary before subject) or do-support (add do/does/did). Types: yes/no (Do you…?), wh- (What/Where/When…?), negative (Don't you…?), tag (…isn't it?).

Rule: find the auxiliary. Move it before the subject. No auxiliary? Add do/does/did. Never use just intonation in written English (You like coffee? is not standard).

Word order

  • She (S) eats (V) cake (O). — standard SVO
  • Cake eats she. — SOV (not English)
  • a lovely little old rectangular green French silver whittling knife — adjective order (opinion→size→age→shape→colour→origin→material→purpose)
  • Never have I seen…inversion after negative adverb

English word order = SVO (subject-verb-object) as default. Adjectives follow a fixed sequence (opinion→size→age→shape→colour→origin→material). Adverb placement varies by type. Deviations signal questions, emphasis, or literary style.

Rule: when in doubt, default to SVO. English position = meaning. Move a word and you change the grammar or the emphasis.

Indirect speech

  • Direct: "I am tired." → Indirect: She said she was tired. (present → past)
  • Direct: "I will come." → Indirect: He said he would come. (will → would)
  • Direct: "I have finished." → Indirect: She said she had finished. (present perfect → past perfect)
  • todaythat day; herethere; tomorrowthe next day

Indirect speech reports someone's words without quotation marks. The mechanism: backshift tenses one step into the past, shift pronouns, and adjust time/place expressions.

Rule: if the reporting verb is past (said, told, asked), shift the reported tense back one step. If the reporting verb is present (says), no shift needed.

English Grammar Basics

  • She is a teacher. — verb be + noun complement
  • He runs every day. — present simple, third-person -s
  • They don't like coffee. — negation with do-support
  • I have two cats. — possession, countable noun, no article before plurals

These sentences demonstrate English Grammar Basics — the foundational patterns every other topic builds on: parts of speech, basic tenses, articles, and simple sentence structure.

If you can identify the verb, the subject, and count the noun correctly, you've nailed the basics that make everything else click.

B2 | Upper Intermediate

  • If I had studied harder, I would have passed. — third conditional
  • The report is being reviewed by the committee. — passive progressive
  • Having finished the exam, she left. — participle clause
  • He denied having taken the money. — complex verb pattern

These are B2 patterns — the CEFR upper-intermediate level. At B2 you handle mixed conditionals, all passive forms, participle clauses, and can argue a point clearly. This is the level most universities and employers require.

Marker: if you can write a structured essay and debate an abstract topic, you're B2.

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: A2B1, 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.
