From Lesson 28 · Grammar Focus — highlighted in gold below.
Hedging language
Soften absolute claims with degree adverbs (broadly, largely), modals (would, tend to) and frequency phrases (more often than not).
Inversion for emphasis
After a negative or restrictive adverbial in front position, invert subject and auxiliary: Never have I seen… / Not only does it…, but…
Cleft sentences (it-cleft, what-cleft)
Split a clause to foreground new information: 'It was the deadline that worried me.' / 'What surprised us was the cost.'
Fronting
Move a non-subject element to the front for emphasis: 'Down the corridor walked the inspector.' / 'Such ideas we rarely hear today.'
Perfect aspect across tenses
Perfect = looking back from a reference point. Choose present / past / future perfect by which time-point you're looking back from.
Advanced modality (speculation & deduction)
Use 'must / can't / might / could + have + p.p.' to deduce or speculate about the past; 'will/would' for confident present deduction.
Mixed and inverted conditionals
Mixed: past condition → present result ('If I had studied medicine, I would be a doctor now'). Inverted: drop 'if' and invert ('Had I known…').
Advanced passives (reporting & causative)
Reporting passive: 'It is said that…' / 'She is believed to have…'. Causative: 'have / get + object + p.p.' = arranging for someone to do it.
Relative clauses (defining, non-defining, reduced)
Defining = essential, no commas. Non-defining = extra info, with commas, no 'that'. Reduce with -ing / -ed for elegance.
Nominalisation
Turn verbs/adjectives into nouns for formal register and density: 'They decided quickly' → 'Their swift decision'.
Cohesion devices (reference, ellipsis, substitution)
Hold long texts together with pronouns ('this', 'such'), ellipsis (cutting repeated words) and substitution ('do so', 'one').
Discourse markers
Signal stance, contrast, addition or concession: admittedly, mind you, having said that, on balance, all things considered.
Reported speech & reporting verbs
Backshift tenses one step back. Use varied reporting verbs: claim, urge, deny, acknowledge, admit, point out, insist (+ patterns).
Word formation patterns
Build C1 forms with prefixes (mis-, over-, under-), suffixes (-ance, -ity, -ship), internal change (long → length) and zero-derivation.
Advanced linking: contrast & concession
Use 'whereas', 'while', 'although', 'despite + -ing/noun', 'much as', 'for all + noun' to balance ideas.
Future forms — the full set
Match the form to the speaker's stance: will (decision/prediction), going to (intention/evidence), present continuous (arrangement), present simple (timetable), future continuous (in progress), future perfect (completed by).
Participle clauses
Replace a finite clause with -ing (active), -ed (passive) or having + p.p. (perfect) to compress meaning: 'Walking into the room, she froze.' / 'Asked about it later, he refused to comment.'
Subjunctive & formal 'should'
After demand/insist/suggest/recommend + that, use the bare infinitive: 'It is essential that he be informed.' Formal 'should' is also common: 'They insisted that he should attend.'
Phrasal & prepositional verbs
Phrasal verbs (verb + particle) can be separable (turn it down) or inseparable (look after him). Many have a one-word Latinate equivalent (work out → calculate) — match register.
Gerund vs infinitive after verbs
Some verbs change meaning with -ing vs to- infinitive: remember/forget/regret/try/stop/mean. Learn pairs: 'I remember locking the door' (memory of doing) vs 'Remember to lock the door' (a task).
