READ OUT LOUD. Choose which marked text you prefer to practice with - macrons or accent marks - and read the text out loud until you feel comfortable and confident. Then, try reading the unmarked text at the bottom. It should be easy for you after practicing with the marked texts. :-)
MACRONS. Here is the text with macrons:
Vulpēs, asinus, leō vēnātum īverant. Praedam asinum partīrī leō iussit. Asinus singulīs singulās partēs pōnēbat aequālēs, sed leō eum dīlaniāvit. Tum vulpēculae negōtium partiendī dedit. Haec, sapientior quam asinus, partem maximam leōnī apposuit, et sibi vix minimam particulam reservāvit. Leō subrīdēbat et eius prūdentiam laudābat. Tandem rogāvit: Unde didicistī tālem prūdentiam? Respondit vulpēs: Calamitās asinī mē docuit quid minōrēs potentiōribus dēbeant."
ACCENT MARKS. Here is the text with ecclesiastical accents, plus some color-coding for the words of three or more syllables (blue: penultimate stress; red: antepenultimate stress):
Vulpes, ásinus, leo venátum íverant. Praedam ásinum partíri leo iussit. Ásinus síngulis síngulas partes ponébat aequáles, sed leo eum dilaniávit. Tum vulpéculae negótium partiéndi dedit. Haec, sapiéntior quam ásinus, partem máximam leóni appósuit, et sibi vix mínimam partículam reservávit. Leo subridébat et eius prudéntiam laudábat. Tandem rogávit: Unde didicísti talem prudéntiam? Respóndit vulpes: Calámitas ásini me dócuit quid minóres potentióribus débeant."
UNMARKED TEXT. Here is the unmarked text - after practicing with the marked text that you prefer, you should not have any trouble with the unmarked text:
Vulpes, asinus, leo venatum iverant. Praedam asinum partiri leo iussit. Asinus singulis singulas partes ponebat aequales, sed leo eum dilaniavit. Tum vulpeculae negotium partiendi dedit. Haec, sapientior quam asinus, partem maximam leoni apposuit, et sibi vix minimam particulam reservavit. Leo subridebat et eius prudentiam laudabat. Tandem rogavit: Unde didicisti talem prudentiam? Respondit vulpes: Calamitas asini me docuit quid minores potentioribus debeant."
