Warm-up

Let's see what comes to mind — no notes, and don't worry about mistakes.

Have a go at this one first. Complete the sentence:

"Whenever I'm cooking, I listen the radio for company."

SPEAK

Say two things you're good at, and one thing you're a little worried about at the moment. Any topic — work, hobbies, family.

Listen in on this conversation

Ben: I'm really keen on trying that new noodle place near the station.

Maya: Me too — I've heard the chef's famous for his dumplings.

Look again at "keen ON" and "famous FOR." Before you check: why do you think these small words are fixed to certain adjectives, rather than following one single rule you could apply everywhere?

Check your idea CLICK
Because English pairs many adjectives, verbs and nouns with one particular preposition — not something you can work out logically, more like a word and its fixed partner: good AT (not "good in"), depend ON (not "depend of"). Native speakers absorb the pairs from hearing them again and again — today you learn the ones you'll use most.
Today: the exact little word that goes with key everyday adjectives, verbs and nouns — good at, depend on, a reason for — so you can talk naturally about yourself, the people around you, and the things that matter, without guessing.

About You: Good At, Keen On, Worried About

For describing yourself and people you know — skills, interests, feelings.

Spot the pattern

Three everyday descriptions:

Before you check: what comes straight after "good", "proud" and "worried" in each one?

Check the pattern CLICK
A preposition (at / of / about), then a noun or an -ing form. Each adjective has its own fixed partner: good AT, proud OF, worried ABOUT. Swap the preposition and the sentence sounds foreign, even though the grammar around it looks fine.
be + adjective + preposition + noun / -ing
good at · keen on · worried about · afraid of · interested in · proud of

From plain to natural

"She doesn't want to try sushi."
→
"She's not keen on trying sushi."

"Keen on" + the -ing form is how people actually talk about interest and enthusiasm — much more common in speech than "want to."

Your turn

1. Your little cousin won't go anywhere near next door's dog, even on a lead.

Explain why: "He's afraid dogs, especially big ones."

2. Your colleague never gets lost, even in a city she's never visited before.

Tell a friend: "She's really good reading maps and finding her way around."

3. Your neighbour keeps mentioning she wants to try growing her own vegetables this year.

Describe it: "She's interested a vegetable patch in the garden."

SPEAK

Tell me two things you're keen on at the moment, and one thing you're worried about. Use "keen on" and "worried about."

What You Do: Depend On, Listen To, Wait For

For everyday habits, relationships and requests.

Spot the pattern

Three everyday habits:

Same question: what's the pattern here?

Check the pattern CLICK
verb + preposition + noun. depend ON, listen TO, look AFTER — each verb has its own fixed partner too. Miss the preposition ("listen the radio") and the sentence breaks; use the wrong one ("depend of") and it sounds foreign.
verb + preposition + noun
depend on · listen to · wait for · look after · agree with · apologise for

Your turn

1. Whether the picnic happens or not really comes down to the forecast.

Say it plainly: "It all the weather tomorrow."

2. Your uncle never misses the football commentary, every single Saturday.

Describe his habit: "He the match on the radio every Saturday."

3. Your friend turned up forty minutes late and felt terrible about it.

Report what happened: "She being so late."

SPEAK

Think of someone in your life. Say one thing you depend on them for, and one thing you always agree with them about.

Reasons, Changes and Answers

For nouns — explaining why, describing a change, giving a solution.

Spot the pattern

Three everyday nouns with their prepositions:

What's the pattern this time?

Check the pattern CLICK
reason FOR, increase IN, answer TO — nouns pair with prepositions too, just like adjectives and verbs. Learn the noun and its preposition as one chunk, and the same pattern also works after adjectives with the -ing form: "interested in growing vegetables", never "interested to grow."
noun + preposition + noun / -ing
a reason for · an increase in · a decrease in · the answer to · an interest in

Your turn

1. Your friend can't work out why the flight got cancelled — nobody's explained it yet.

Say it: "Nobody's told us the reason the cancellation yet."

2. The exam had one tricky maths question that nobody could finish, not even the teacher.

Say it: "Even the teacher wasn't sure of the answer that last question."

3. House prices in the area have gone up noticeably this year. Choose the right option: "There's been a big ___ house prices this year."

SPEAK

Think about your town or city. Say one reason for a recent change there, starting with "The reason for..."

Your Turn to Talk

Time to use all three patterns talking about yourself. You do the talking.

The situation

Think about yourself right now — your interests, the people or things you depend on, something you're a little worried about, something you're proud of.

Talk about yourself out loud for one minute. Try to use:

01:00

Now put it in writing

Write a short message (3–5 sentences) introducing yourself to a new colleague or neighbour. Use at least one adjective + preposition, one verb + preposition, and one noun + preposition — the checker will tell you which ones it finds.

Mix It Up

Real life doesn't tell you which preposition to use. Here everything is mixed — you decide.

Fix the mistakes

Each sentence has one preposition mistake. Rewrite the whole sentence correctly.

1. "She's good in maths, especially algebra."

2. "This all depends of the weather forecast."

3. "I never listen the radio before nine in the morning."

4. "He's afraid from spiders, even tiny ones."

Which word fits?

5. "My nephew's really ___ learning to skateboard — he practises every afternoon."

6. "Could you ___ my cat while I'm at the conference next week?"

7. "I totally ___ you — we should leave earlier next time."

SPEAK

One-minute challenge: you're introducing a close friend to someone new. Describe them — what they're good at, what they're keen on, and what they depend on you for. Use the timer above if you like the pressure.

What Do You Remember?

First, from earlier lessons

1. A preposition you already knew before today — complete it: "We landed the airport just after midnight."

2. Say it out loud: give one example with "in" for a period of time, and one example with "on" for a day or date.

Compare with a possible answer CLICK
One possible answer: "in the evening" (a period of time) and "on Tuesday" (a day). Those prepositions of time and place are a different family from today's — today's pair with specific adjectives, verbs and nouns instead.

Now, today's grammar — fresh sentences, no looking back

3. Your grandmother won't get in a lift, ever, not even for one floor.

Explain why: "She's afraid small spaces."

4. Whether you go camping this weekend depends entirely on one thing.

Say it: "It whether it stops raining."

5. Your friend won't say why they cancelled dinner at the last minute.

Say it: "They haven't given a reason cancelling."

Think back

Which practice helped you most today — fixing the mistakes, choosing the right preposition, or the speaking tasks? Say why you think that one worked for you.

Can you now...?

At the start we said: the exact preposition for key everyday adjectives, verbs and nouns. Tick what's true:

Anything you didn't tick — go back to that tab and try the exercises once more. They'll still check your answers.
