Topic Explanation and Use
Core idea
This lesson helps you say the same idea with sharper, more natural vocabulary.
Prepositions in Context is best learned in chunks such as interested in, depend on, and on time rather than as single words.
Use these phrases when a verb, adjective, or time expression needs a fixed partner.
At B2 level, learn fewer words but learn them well: meaning, collocation, and one model sentence.
Use it here
- Study the full chunk, not only the preposition.
- Notice whether the phrase shows time, place, direction, or a fixed pattern.
- Check for extra prepositions after verbs that do not need them.
Watch it work
Remember this
- Choose the meaning first before you choose the word.
- Learn the word with a natural collocation or partner phrase.
- Use the new word in one short sentence right away.
- Replace vague words only when the new word stays accurate.
- Keep the register stable so the language fits the task.
