The correct answers are: The head chef asked whether they had seasoned the soup and insisted that they clean their stations immediately. The head chef asked if they had seasoned the soup and told them to clean their stations immediately.
To report a yes/no question, you must use if or whether followed by standard subject-verb word order (no inversion). "Asked had they" and "whether had they" are incorrect because they keep the auxiliary verb before the subject.
For reporting commands, you can use a verb like told/ordered + object + to-infinitive ("told them to clean"), or a verb like insisted/demanded + that clause using the subjunctive mood ("insisted that they clean"). Note that demand cannot take an object pronoun before an infinitive ("demanded them to clean" is incorrect).
Indirect speech
If you've ever tried to retell what someone said and ended up with a verb-tense mess (She said she will come — wait, would come?), you've hit indirect speech. The rules look intricate but reduce to one move: when the reporting verb is past, shift everything in the reported clause one step into the past. Master that and reporting other people's words stops being a guessing game.
Indirect speech reports what someone said without quoting them: "I like apples" → He said that he liked apples. The core mechanism is backshift — tenses retreat one step into the past — plus pronoun and time-expression shifts.
Questions
If you've ever asked You like coffee? with rising intonation and gotten a confused look — you've felt the gap between casual and grammatical English questions. Many languages form questions with intonation alone, but English usually requires inversion (Are you ready?) or do-support (Do you like coffee?). Skip the structure and your questions sound like uncertain statements.
Questions in English use inversion of subject and an auxiliary (Can she dance?) or do-support when no auxiliary is present (Does the milk go in the fridge?). Yes/no questions, wh-questions, negative questions, and tag questions all share this machinery.
Imperative mood
If you've ever told a stranger Sit down! in English and watched their face drop, you've felt the imperative's main pitfall: it's grammatically simple but socially loaded. In English, bare commands often come across as rude, even when you mean them politely. Knowing when to soften them (Could you sit down?) is what separates abrupt from polite.
The imperative mood is the form for commands, instructions, and requests: Sit down, Don't touch, Have a nice trip. Bare verb form, no stated subject, negated with don't.
Subjunctive mood
If you've heard if I were you and wondered why it's not if I was you — you've met the past subjunctive. English barely marks the subjunctive anymore, but in formal writing and a few stock phrases, getting it right (or wrong) is one of the clearest signals of a careful writer. I demand that he be present. / If I were richer. — both subjunctive, both reading as wrong if you swap them out.
The subjunctive mood marks hypothetical or counterfactual contexts. Two main forms: present subjunctive in that-clauses after verbs of recommendation (I suggest that he go) and past subjunctive were in unreal conditionals (If I were you). Mostly invisible in modern English, but unmistakable when present.
Word Order
If your first language has flexible word order — Russian, Latin, German, Japanese — English can feel rigid. You can't just rearrange words for emphasis the way you would at home; the grammar tracks position, not just inflection. Get the order wrong and the sentence either changes meaning or stops making sense.
Word order is the sequence of words in a sentence. English is an SVO language — subject, verb, object. The order of adjectives and modifiers in a noun phrase also follows fixed patterns. Get this right and your English instantly sounds more natural.
C1 | Advanced
If you've ever sat through a lecture in English, written a complaint letter, or argued a point in a meeting and come out feeling actually understood — not just tolerated — you've felt what C1 looks like. The level matters because it's where most universities, certifications, and skilled-work environments draw their language line.
C1 is the advanced level in the CEFR framework, demanding fluent and flexible language: inversion for emphasis, mixed and advanced conditionals, formal subjunctive, cleft sentences, and complex nominal phrases — all used appropriately across registers.
Difficulty: Hard
If easy and medium questions are clicking but you still feel exposed in real conversation or formal writing, you've outgrown the basics. Hard material is where the gaps you didn't know you had show up: the distractor that "sounds right", the rule that interacts with another rule, the case where context changes the answer. It's where genuine fluency is built.
The Hard difficulty tag marks upper-intermediate to advanced challenges — typically B2 and above. Interacting rules, edge cases, plausible distractors, and contexts that require genuine understanding rather than surface pattern-matching.
