Drill a, an, the and the zero article across sound rules, first mention, unique nouns and generic plurals, with the rule shown after each answer.
English has three articles — a, an and the — plus a fourth option that learners forget: no article at all. This drill tests all four across the situations that actually decide the choice: the sound rule behind an hour and a university, first mention against second mention, unique and specified nouns, and the generic plurals and institutions that take nothing. Each answer is followed by the corrected sentence and the rule that produced it, so the pattern sticks rather than the single item.

The zero article is always on offer, so the drill tests the real decision instead of a two-way guess.
Each answer shows the full sentence written correctly alongside the rule behind it.
Sound rule, indefinite, definite and zero article can be drilled separately to target one weakness.
It depends on the sound that follows, not the letter: an goes before a vowel sound and a before a consonant sound. That gives an hour and an MP because the h is silent and M is said 'em', but a university and a one-way street because those start with 'yoo' and 'w' sounds.
Use the once the listener can identify which one you mean — on second mention, for unique things (the sun, the moon), after superlatives and ordinals, and when a following phrase pins it down, as in 'the book on the table'. Use a or an the first time you introduce a singular countable noun.
Plural and uncountable nouns used generally take nothing — 'cats sleep a lot', 'water boils'. So do most country and city names, languages, subjects, meals, sports, and institutions used for their purpose: go to school, go to bed, travel by train.
Without the article you mean the activity — attending as a pupil. With the article you mean the building itself, so a parent collecting forms drives to the school. The same split runs through hospital, church, prison and university in British English.
