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:
Lupus canem vidēns bene sagīnātum, "Quanta est (inquit) fēlīcitās tua! Tū, ut vidēris, lautē vīvis, at ego famē ēnecor." Tum canis, "Licet (inquit) mēcum in urbem veniās et eādem fēlīcitāte fruāris." Lupus condiciōnem accēpit. Dum ūnā eunt, animadvertit lupus in collō canis attrītōs pilōs. "Quid hoc est?" inquit. "Num iugum sustinēs? Cervīx enim tua tōta est glabra." "Nihil est," canis respondit, "sed interdiū mē adligant, ut noctū sim vigilantior; atque haec sunt vestīgia collāris quod cervīcī circumdarī solet." Tum lupus, "Valē (inquit) amīce! Nihil moror fēlīcitātem servitūte ēmptam."
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):
Lupus canem videns bene saginátum, "Quanta est (inquit) felícitas tua! Tu, ut vidéris, laute vivis, at ego fame énecor." Tum canis, "Licet (inquit) mecum in urbem vénias et eádem felicitáte fruáris." Lupus condiciónem accépit. Dum una eunt, animadvértit lupus in collo canis attrítos pilos. "Quid hoc est?" inquit. "Num iugum sústines? Cervix enim tua tota est glabra." "Nihil est," canis respóndit, "sed intérdiu me ádligant, ut noctu sim vigilántior; atque haec sunt vestígia colláris quod cervíci circúmdari solet." Tum lupus, "Vale (inquit) amíce! Nihil moror felicitátem servitúte emptam."
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:
Lupus canem videns bene saginatum, "Quanta est (inquit) felicitas tua! Tu, ut videris, laute vivis, at ego fame enecor." Tum canis, "Licet (inquit) mecum in urbem venias et eadem felicitate fruaris." Lupus condicionem accepit. Dum una eunt, animadvertit lupus in collo canis attritos pilos. "Quid hoc est?" inquit. "Num iugum sustines? Cervix enim tua tota est glabra." "Nihil est," canis respondit, "sed interdiu me adligant, ut noctu sim vigilantior; atque haec sunt vestigia collaris quod cervici circumdari solet." Tum lupus, "Vale (inquit) amice! Nihil moror felicitatem servitute emptam."
