Reconstruct the confused farmer's police statement about his encounter with polite extraterrestrials. Select the correct grammar for each blank.
"The spaceship landed, and the green leader stepped out. He asked me where _________________________. After I pointed to the field, they instructed me _________________________ them the barn."

The correct answers are the cows were and to show.

First blank: In reported questions, we do not use question word order. "Where are the cows?" changes to statement word order (Subject + Verb) and shifts back in tense: "where the cows were."

Second blank: For reported commands or instructions, we use the infinitive form: instruct + object + to + verb ("instructed me to show").

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.

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.

Infinitive

  • I want to go. — to-infinitive after want
  • She can swim. — bare infinitive after modal
  • Let me help. — bare infinitive after let
  • I enjoy to read. — wrong (enjoy takes gerund, not infinitive)

The infinitive has two forms: to-infinitive (to go) after verbs like want, decide, plan, hope; bare infinitive (go) after modals and causatives (let, make, help).

Rule: after want, need, decide, plan, hope, expect, agree, refuse → to-infinitive. After can, will, must, let, make → bare infinitive. After enjoy, avoid, finishgerund, NOT infinitive.

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).

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.
