The correct answers are You should wear a cool hat tonight. and You shouldn't try to cut it yourself to fix it!
When giving advice, we use "should" or "shouldn't" followed directly by the base form of the verb (e.g., wear, try).
We never use "to" after should (so "should to cancel" is incorrect), and we do not use the -ing form (so "should wearing" is incorrect).
Modal verb
- ✅ She can swim. — ❌ She can to swim. (modal + bare infinitive, no to)
- ✅ You must leave now. — strong obligation
- ✅ It might rain. — possibility (~50%)
- ✅ He should apologise. — advice/recommendation
Modal verbs (can, could, may, might, must, shall, should, will, would) are auxiliaries expressing ability, permission, possibility, obligation, or speculation. Always + bare infinitive. Never inflected (she can, not she cans).
Rule: modals never take to after them, never add -s for third person, and can't combine directly (must can ❌ — use must be able to).
English Grammar Basics
- She is a teacher. — verb be + noun complement
- He runs every day. — present simple, third-person -s
- They don't like coffee. — negation with do-support
- I have two cats. — possession, countable noun, no article before plurals
These sentences demonstrate English Grammar Basics — the foundational patterns every other topic builds on: parts of speech, basic tenses, articles, and simple sentence structure.
If you can identify the verb, the subject, and count the noun correctly, you've nailed the basics that make everything else click.
Humor
- "I before E, except after C" — weird, right? — playful self-contradiction
- Grammar joke: A panda eats, shoots, and leaves. — comma changes everything
- Silly contexts make rules memorable: the sillier the sentence, the harder it is to forget
- Entertainment is a learning strategy, not a distraction
Humor marks practice material that's deliberately entertaining. The grammar is real; the packaging is playful. Designed to boost engagement and make rules stick through association.
Why it works: memory anchors to emotion. A funny example of comma misuse is remembered longer than a dry rule statement.
A2 | Elementary | Pre-intermediate
- ✅ I went to the cinema yesterday. — past simple
- ✅ I have visited Paris twice. — present perfect (life experience)
- ✅ If it rains, I'll take an umbrella. — first conditional
- ✅ You should see a doctor. — modal for advice
These patterns are A2 — the second CEFR level. At A2 you move past survival phrases into real grammar: past tenses, the present perfect, basic conditionals, and modals for advice/obligation.
Marker: if you can describe yesterday and give simple advice, but struggle with abstractions or nuance, you're at A2.
Medium
- If I were you, I would apologise. — one rule (second conditional), but distractors like was tempt you
- Answers require active thought, not instant pattern recognition
- Vocabulary and context are realistic, not artificially simplified
- Usually tests one rule, but the wrong answers are plausible
Medium marks middle-difficulty challenges: A2–B1, one rule tested, but with realistic distractors that require genuine understanding.
Use "Medium" when Easy feels too obvious but Hard feels overwhelming. This is where most productive learning happens — the sweet spot of difficulty.
