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:
Asinus, pelle leōnis indūtus, territābat hominēs et bēstiās, tanquam leō esset. Sed fōrte, dum sē celerius movet, aurēs ēminēbant: unde āgnitus, in pīstrīnum abductus est, ubi poenās petulantiae dedit.
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):
Ásinus, pelle leónis indútus, territábat hómines et béstias, tanquam leo esset. Sed forte, dum se celérius movet, aures eminébant: unde ágnitus, in pistrínum abdúctus est, ubi poenas petulántiae dedit.
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:
Asinus,
pelle leonis indutus,
territabat homines et bestias,
tanquam leo esset.
Sed forte,
dum se celerius movet,
aures eminebant:
unde agnitus,
in pistrinum abductus est,
ubi poenas petulantiae dedit.
