Help the detective finish her report about the Great Cookie Heist by choosing the correct verb forms.
When I arrived at the kitchen counter, the cookie jar _________________________ completely empty. The prime suspects _________________________ my two roommates, who both had chocolate on their faces. I _________________________ absolutely shocked that they didn't save me a single crumb!

When I arrived at the kitchen counter, the cookie jar was completely empty. The prime suspects were my two roommates, who both had chocolate on their faces. I was absolutely shocked that they didn't save me a single crumb!

Use was for singular subjects (the cookie jar, I) and were for plural subjects (the prime suspects).

Be

If your first weeks of English felt like a battle with am, is, are — you've already met the most common verb in the language. Every form of be is irregular, and you can't avoid them: they're in introductions, descriptions, questions, the present continuous, the past, and the passive voice. Get them automatic and the rest of English grammar gets noticeably less stressful.

The verb be has eight forms — be, am, is, are, being, was, were, been — more than any other English verb. Functions as a copula linking subject to complement (She is a doctor) and as an auxiliary for progressive tenses and the passive voice.

Past tense

If you've ever told a story in English and felt the timeline get tangled — I came home, the dog ate, the cat slept — you've hit the limits of using simple past for everything. The past tense system has four forms specifically because real stories have layered timing: things that happened before other things, actions caught in progress, sequences of completed events.

The past tense has four English forms: simple past (I walked), past progressive (I was walking), past perfect (I had walked — earlier than another past event), past perfect progressive (I had been walking — ongoing up to a past point). Plus irregular verbs for the simple-past form.

Verb

If grammar feels overwhelming, the fix is almost always to focus on verbs first. They carry the action, the time, the mood, and the voice — a single verb form decides whether your sentence reads as past or present, fact or hypothetical, active or passive. Get verbs solid and the rest of grammar suddenly looks much smaller.

A verb expresses action, state, or occurrence — the engine of every English sentence. Most verbs have five forms (base, -s, past tense, past participle, -ing); be has eight; modal verbs have fewer. Verbs carry tense, aspect, mood, and voice.

Humor

If you've ever reached the third drill of present perfect and felt your eyes glaze over, you've hit the limits of dry repetition. Practice that's even mildly funny is far easier to come back to — and far easier to remember weeks later. That's the whole point of the Humor tag.

The Humor tag marks questions where the author has tried to make the practice entertaining alongside instructive. Subjective, sometimes silly, but designed to keep you engaged long enough for the rule to stick.

A1 | Elementary | Beginners

If you can say your name, ask Where is the toilet?, and read a simple bus sign — but freeze when someone speaks at normal speed — you're at A1. That's not a problem to fix; it's the level where most learners actually live for a while, and recognising it lets you pick the right material instead of drowning in advanced grammar that wasn't meant for you yet.

A1 is the starting level of the CEFR framework, covering basic everyday communication: greetings, introductions, simple personal questions, present-tense forms of be/have/do, and core determiners and prepositions.

Difficulty: Easy

If a textbook leaves you confused, sometimes the issue isn't the topic — it's that the practice material is layered with extra complications. Filtering by Easy strips that away. You get one rule at a time, in plain everyday language, with no trick questions. It's how you make a shaky foundation solid before stacking more on top.

The Easy difficulty tag marks beginner-level questions and challenges — typically A1 or early A2. Single-rule focus, short sentences, common vocabulary, one clear correct answer.
