The correct answers are I saw myself, I had ever been, and I was eating.
When we report questions (indirect questions), two major changes happen:
- Word Order: We stop using question word order (verb-subject) and switch to normal affirmative statement word order (subject-verb). We also drop auxiliary verbs like do/did.
- Backshifting: Because the reporting verbs (asked, wanted to know, yelled) are in the past tense, the verbs inside the questions shift back one tense (present simple $\rightarrow$ past simple, present perfect $\rightarrow$ past perfect, present continuous $\rightarrow$ past continuous).
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.
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.
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.
Verb tense
If you've ever frozen mid-sentence wondering whether to say I worked or I have worked, I had been doing or I was doing — you've felt the weight of English's tense system. Twelve forms, each with a specific job, and the wrong choice subtly misrepresents your meaning. Mastering tenses is the longest single project in English grammar, but it's also the one with the biggest payoff.
Verb tense signals when an action happens. English has three time references (past, present, future) combined with three aspects (simple, progressive, perfect), giving twelve standard forms. Each carries a specific meaning beyond just timing.
Clause
If you've ever been told your sentence is a "run-on" or that you've used a comma where there should be a semicolon — you've hit the limits of writing without seeing clauses. Get this concept solid and most punctuation problems quietly disappear: you can finally tell a complete thought from a fragment without guessing.
A clause is a grammatical unit built around a verb, usually with a subject and a predicate. Independent clauses stand alone (I missed the bus); dependent clauses can't (Because I overslept). Combine them and you build complex sentences.
B2 | Upper Intermediate
If a university admissions team or visa office has ever asked you for an English test score, B2 is probably the level they had in mind. It's the threshold where your English stops being a constraint and starts being a tool — and the line between B1 and B2 is often the line between "stuck in beginner classes" and "ready to study or work in English."
B2 is the upper-intermediate level in the CEFR framework, demanding flexible control of mixed conditionals, passive voice across tenses, reported speech with backshifting, and participle clauses.
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.
