Help the frustrated owner complete the diary entry about their very lazy cat by dragging the correct verbs into the blanks.
My cat, Sir Pounce, sleeps for 18 hours a day. He doesn't catch mice because he thinks it's too much work. Instead, he just waits by his food bowl until I feed him.
My cat, Sir Pounce, sleeps for 18 hours a day.
We add an "-s" to the base verb for third-person singular subjects (he, she, it, or "My cat") in the present simple tense.
He doesn't catch mice because he thinks it's too much work.
To make a negative sentence for a third-person singular subject, we use "doesn't" (does not) followed by the base form of the verb.
Instead, he just waits by his food bowl until I feed him.
Again, "he" is a third-person singular subject, so the verb "wait" needs an "-s" at the end.
Present tense
Simple present vs present progressive: simple present = habits, routines, permanent facts (I work here). Present progressive = right now, temporary, changing (I'm working from home today). The most common confusion: using progressive for habits (I'm working here ❌ for permanent job) or simple for right-now (I work now ❌ for current activity).
The present tense has four forms: simple, progressive, perfect, perfect progressive — each relating the action to "now" differently.
Diagnostic: is it a habit/permanent fact? → simple. Happening right now? → progressive. Started in past but still relevant? → perfect. Ongoing duration up to now? → perfect progressive.
Simple tense
Simple vs progressive vs perfect: simple = "just the fact" (I work). Progressive = "ongoing right now" (I am working). Perfect = "connected to a reference time" (I have worked). Simple is the default — use it unless you have a reason to add progressive or perfect meaning.
The simple aspect = unmarked form. Habits, facts, completed events, scheduled future. The starting point for all tense learning.
Diagnostic: do you need to signal "ongoing" (progressive) or "relevant to now" (perfect)? No? → simple is correct. Most sentences use simple tense — it's the unmarked default.
Habits and Routines
Used to vs would for past habits: both describe repeated past actions, but used to works for states AND actions (I used to live there), while would works only for actions (I would walk to school). You can't say I would live there for a past state — that changes the meaning to a conditional.
Habits and routines combines present simple + frequency adverbs (current habits) with used to/would (past habits that have stopped).
Diagnostic: is it a past state (live, know, have)? → only used to. A past repeated action (walk, visit, bring)? → either used to or would.
Humor
Humor vs serious practice: both teach the same rules. The difference is engagement — funny material keeps you coming back and creates stronger memory hooks. If dry drills bore you into quitting, humorous practice is more effective because you actually do it.
The Humor tag filters for entertaining practice: silly contexts, wordplay, absurd examples — all testing real grammar rules underneath.
Diagnostic: if you find yourself dreading practice → try filtering by Humor. If you're preparing for a formal exam and want serious register → filter it out.
A1 | Elementary | Beginners
A1 vs A2: A1 covers isolated survival phrases (Where is…?, I am…, How much?). A2 handles connected sentences about familiar routines and simple past events. If you can manage short fixed phrases but not string together original sentences about your day, you're still A1.
A1 is the entry level of the CEFR: greetings, introductions, numbers, basic present tense, and core function words.
Diagnostic: can you describe yesterday using past tense? No → A1. Yes → you're moving into A2.
Easy
Easy vs Medium vs Hard: Easy = one rule, obvious answer, A1–A2. Medium = one rule but realistic distractors, A2–B1. Hard = interacting rules, edge cases, B2+. Start Easy to check you have the basics before moving up.
The Easy tag filters for single-rule, short-sentence, common-vocabulary challenges designed for beginners or for anyone wanting a confidence check on fundamentals.
Diagnostic: if you get Easy questions wrong, stay here — your foundations need work. If they feel trivial, move to Medium.
