Common Grammar Fixes: Tenses, Articles, and Agreement

Even advanced English speakers occasionally slip up with certain high-frequency grammar rules. For instance, because stative verbs describe a state rather than an action, we say "I know the answer" instead of "I am knowing the answer." Similarly, the phrase "one of the" must always be followed by a plural noun and a singular verb, as in "One of my friends is here."

This challenge targets these common conversational and written errors to help polish your English. You will practice identifying correct stative verbs, choosing the simple past over the present perfect for specific past dates, and remembering to use the base verb after did (e.g., "I didn't know"). You will also tackle tricky subject-verb agreement rules, proper article usage for professions (like "I am a software engineer"), and uncountable nouns that cannot be pluralized, such as advice, furniture, and equipment.

You'll work through 14 questions in a mix of single-choice, multi-choice, drop-down, and drag-and-drop formats. Try the quiz to check your knowledge!
