Five short exercises targeting common mistakes English learners make at this level: the “explain to” preposition, building adjectives from nouns, avoiding double negatives, choosing the right tense for general truths vs specific events, and emotion vocabulary. Work through each section, check your answers, and see where you stand.

1 · “Explain to” — Fix the Preposition
Choose the correct version. “Explain” always needs “to” before a person.

2 · Word Building — Noun → Adjective

Suffix bank: -ful   -ous   -ive   -ed   (some words change form without a suffix)

relief feeling glad worry is over
remorse feeling guilty and regretful

3 · Negative Sentences — Logic & Form
