Dear Mr. Sterling,
I know you are incredibly busy, but would you mind reviewing my presentation before the big meeting?
If it's not too much trouble, could you share the latest marketing data with me so I can update the charts?
Finally, would you mind if I took tomorrow morning off to recover from the stress of this project?
I know you are incredibly busy, but would you mind reviewing my presentation before the big meeting?
The verb reviewing is in the -ing form (gerund), which perfectly follows would you mind. "Could you" requires the base form (review).
If it's not too much trouble, could you share the latest marketing data with me so I can update the charts?
The verb share is in its base form, which requires could you. "Would you mind" would require sharing.
Finally, would you mind if I took tomorrow morning off to recover from the stress of this project?
To ask for permission politely, we use would you mind if I + the past tense verb (took). This creates a hypothetical, extremely polite request.
Modal verb
A modal verb is a special class of auxiliary — can, could, may, might, must, shall, should, will, would — that adds shades of meaning around possibility, ability, permission, obligation, or speculation. I can swim (ability), You should rest (advice), It might rain (possibility), You must leave (obligation).
Modals are grammatically peculiar: no -s in the third person (she can, not she cans), no infinitive, no participle, followed by the bare verb (I can swim, never I can to swim). Mastering them is the move from describing facts to expressing how you feel about them — likelihood, necessity, recommendation.
Gerund
A gerund is the -ing form of a verb used as a noun — swimming, reading, being late. It can sit in any position a noun can: as the subject (Swimming is fun), as the object of a verb (I enjoy swimming), or as the complement of a preposition (She's good at swimming).
Gerunds matter because dozens of common English verbs and almost every preposition force you into the -ing form. Pick the wrong shape — I enjoy to swim, good at to swim — and the sentence sounds clearly off to a native speaker. Knowing which contexts demand a gerund (vs. an infinitive) is what makes verb patterns click.
Conditional sentence
A conditional sentence describes one situation as depending on another. It pairs a condition clause (usually starting with if) with a consequence clause: If it rains, we'll stay in. The condition can refer to general truths, real future possibilities, hypothetical present situations, or unreal past situations — and each type uses a specific tense pattern.
English teaching groups these into zero, first, second, third, and mixed conditionals. Mastering them lets you talk about plans, regrets, hypotheticals, and warnings — territory you can't reach with simple present and past tenses alone.
English grammar
English grammar is the system of rules that govern how meanings are encoded in English — covering everything from word formation to phrase, clause, and sentence structure, up to the patterns that connect sentences in longer texts. It includes parts of speech, tenses, voice, mood, word order, punctuation, and the agreement rules that hold them together.
Grammar isn't a list of arbitrary do's and don'ts — it's the predictable system that lets you say things you've never said before and be understood. Learning it deliberately is the fastest way to move from "I can be understood" to "I can express what I actually mean".
Questions
Questions in English are typically formed by inverting the subject and an auxiliary verb: She can dance → Can she dance?. When there's no auxiliary present, English adds do-support: The milk goes in the fridge → Does the milk go in the fridge?. The same pattern handles wh-questions (Where do you live?) and negative questions (Doesn't he know?).
The trickiest variant is indirect questions — I wonder where he is, not where is he. The inversion drops because the question is embedded inside another clause. Getting this right is one of the bigger jumps from A2 to B1 fluency.
Verb mood
Verb mood is the verb form that signals the speaker's attitude toward the action — whether it's a fact, a command, a hypothetical, or a recommendation. English has four main moods: indicative for statements and questions about facts (She works here), imperative for commands and instructions (Sit down!), subjunctive for hypothetical or formal-recommendation contexts (If I were you; I suggest he go), and conditional for would/could constructions (I would go).
Most English sentences are indicative — that's the default. The other three moods are smaller categories, but each marks a specific shift in meaning that can't be expressed any other way.
B2 | Upper Intermediate
B2 is the upper-intermediate level in the CEFR framework, sitting between B1 and C1. At B2 you can read editorials, follow most TED talks without subtitles, and hold extended conversations on abstract topics — including topics outside your everyday life.
Grammatically, B2 means flexible control of mixed conditionals, passive voice across tenses, reported speech with proper backshifting, and participle clauses. B2 is the standard target for university entrance exams (IELTS 5.5–6.5, TOEFL 87–109) and most skilled-migration thresholds — knowing whether you're there shapes your study plan.
Difficulty: Medium
The Medium difficulty tag marks questions and challenges in the middle of the difficulty range — typically suitable for A2 to B1 learners. Expect a single rule with realistic distractors, longer sentences, and contexts where you have to think before answering rather than reading off the obvious choice.
Filter by Medium when you're past the absolute basics and ready to consolidate. It's the level where most lasting progress happens — easy enough that you can finish without exhausting concentration, hard enough that getting it right means you've actually understood.
