The correct answers are: I started learning spells five years ago. I have practiced the invisibility spell for six months. I have been a certified wizard since last December.
Five years ago correctly uses ago with the simple past tense (started).
For six months correctly uses for to show a duration of time.
Since last December correctly uses since to indicate a specific starting point.
"Since five years" is incorrect because "five years" is a duration (it should be for five years). "For two weeks ago" incorrectly mixes two different time expressions.
Preposition
- ✅ interested in — ❌ interested on
- ✅ good at football — ❌ good in football
- ✅ depend on — ❌ depend of
- ✅ arrive at the station — ❌ arrive to the station
Prepositions link nouns to the rest of the sentence: time (at 5pm), place (in London), manner (with care), abstract (afraid of). Most are idiomatic — the "correct" preposition must be memorised with each verb/adjective combination.
Rule: there is no universal rule. English prepositions are learned by combination: interested IN, good AT, depend ON, afraid OF. Your native language's equivalent will often mislead.
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.
Easy
- She is a teacher. — one verb form, one rule
- I have two cats. — basic possession, short sentence
- He doesn't like coffee. — simple negation with do-support
- Only one answer is clearly correct; distractors are obviously wrong.
Easy marks beginner-level challenges: A1–early A2, one rule at a time, everyday vocabulary, no trick questions.
Use "Easy" when you want to build confidence on a specific rule without interference from other grammar or tricky contexts.
