The correct answers are I am still the captain of this ship, aren't I?, Let's sail toward that massive storm, shall we?, and Hand me those binoculars, will you?
These are special exceptions for question tags:
- The negative tag for "I am" is aren't I? (or the very formal am I not?).
- Suggestions starting with "Let's" take the tag shall we?
- Imperatives (commands) usually take will you?, would you?, or could you? Negative commands (like "Don't drop...") always take will you?
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.
Auxiliary verb
If you've ever wondered why English asks Do you know? instead of Know you?, or how a single sentence can carry tense, aspect, AND voice (has been being cleaned), you've felt the work of auxiliary verbs. They're tiny words that quietly carry most of English's grammatical machinery — get them wrong and questions, negatives, and tenses all fall apart.
An auxiliary verb combines with a main verb to add grammatical meaning. The English auxiliaries are be, have, do, and the modal verbs (can, will, should…). They handle questions (Do you?), negation (don't), tense and aspect (has gone, is going), and passive voice (was eaten).
Negation
If your native language uses double negatives (I don't see nothing) — like Russian, Spanish, or French — you've probably been told this is wrong in English and not been entirely sure what the fix is. Standard English uses one negative per clause: either I saw nothing or I didn't see anything, never both. Once you internalise that single rule, your written English clears up a lot.
Negation in English uses not after an auxiliary or modal verb: I am not going. Without an auxiliary, you add do-support (I do not go). Negative words like never and nobody already negate the clause — adding not on top creates non-standard double negatives.
Modal verb
If you've ever struggled with the difference between You must do this (strong command) and You should do this (advice) — or It might rain (possible) and It will rain (certain) — you've felt how much modal verbs do in English. They're how the language signals certainty, obligation, possibility, and politeness, and getting them right is what stops your speech from sounding either pushy or wishy-washy.
A modal verb is an auxiliary — can, could, may, might, must, shall, should, will, would — adding meaning around ability, permission, possibility, obligation, or speculation. Always followed by the bare infinitive (can swim, never can to swim), and never inflected for person.
B1 | Intermediate
If you can hold a conversation about your weekend, explain why you're late, and follow a short news story without panicking — but still feel lost in fast or technical English — you're probably operating at B1. Knowing this matters: study material at the wrong level either bores you or burns you out, and B1 is the typical target for travel, casual work, and most everyday social English.
B1 is the intermediate level in the CEFR framework, where you handle everyday English independently and start combining ideas with complex sentences, passive voice, and modal verbs.
Difficulty: Medium
If easy questions feel too obvious but hard questions leave you guessing, you're probably ready for Medium — the level where most real learning happens. It pushes just enough to expose the rules you don't quite have yet, without burying you in edge cases. This is where steady fluency is built, one well-aimed challenge at a time.
The Medium difficulty tag marks middle-range challenges — typically A2 to B1. One rule per question, realistic distractors, and contexts that require active thought rather than instant recognition.
