Read Agent 007.5's disastrous mission report to headquarters. Select ALL the sentences that correctly use the causative structure to describe his misfortunes.

The correct answers are I had my secret gadget stolen on the train. and I got my sunglasses broken during the chase.

The structure have/get + object + past participle isn't just for services we ask for; it can also be used to describe experiencing something bad, like a theft or an accident!

"I had stolen my secret gadget" means the agent was the thief!

"I had my passport steal" is incorrect because it uses the base verb ("steal") instead of the past participle ("stolen").

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.

Passive voice

  • The meal was cooked by the chef. — passive (action matters)
  • Mistakes were made. — passive, agent hidden (evasive)
  • ✅ Active: The chef cooked the meal. — stronger, clearer
  • The report was being been written. — malformed passive

The passive = be + past participle. Object becomes subject. Use it when the doer is unknown, irrelevant, or obvious. Avoid when it hides responsibility or weakens prose.

Formula: find the active object → make it the subject → use be (matching tense) + past participle → optionally add by + agent.

Participle

  • a broken window — past participle as adjective
  • the running water — present participle as adjective
  • I have eaten. — past participle in perfect tense
  • She is sleeping. — present participle in progressive tense
  • I have went. — wrong (past tense, not past participle: use gone)

A participle is a verb form that also works as an adjective. Present (-ing): running, sleeping. Past (-ed or irregular): broken, written, gone. Used in progressive tenses, perfect tenses, passive voice, and as modifiers.

Trap: don't confuse past tense (went) with past participle (gone). After have/has/had → always past participle.

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.

Object

  • Sam fed the dogs. — direct object (what was fed)
  • She sent him a present. — indirect object (who received it)
  • She waited for Lucy. — prepositional object (after preposition)
  • I gave her a book. — indirect + direct object together

An object is what a verb acts on or directs its action toward. Direct = the thing affected. Indirect = the recipient. Prepositional = after a preposition.

Test: Verb + what/whom? = direct object. Verb + to/for whom? = indirect object. After a preposition? = prepositional object.

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: 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.
