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:
Ōpilio quīdam saevā lue tōtum suum gregem perdiderat. Quod cum lupus cognōvisset, ad ōpiliōnem accessit, dolōrem socium eī significāturus. Ergone vērum est (inquit) tē tantam fēcisse iactūram, tōtumque ovium gregem perdidisse? Heu! quam tuī mē miseret! Quantus est dolor meus! Grātiās agō, rēspondit ōpilio; videō tē calamitāte meā vehementer commōtum. Semper enim, addit canis, dolōre afficitur lupus, ubī ex aliōrum calamitāte ipse iactūram facit.
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):
Opílio quidam saeva lue totum suum gregem perdíderat. Quod cum lupus cognovísset, ad opiliónem accéssit, dolórem sócium ei significatúrus. Érgone verum est (inquit) te tantam fecísse iactúram, totúmque óvium gregem perdidísse? Heu! quam tui me míseret! Quantus est dolor meus! Grátias ago, respóndit ópilio; vídeo te calamitáte mea veheménter commótum. Semper enim, addit canis, dolóre affícitur lupus, ubi ex aliórum calamitáte ipse iactúram facit.
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:
Opilio quidam
saeva lue
totum suum gregem perdiderat.
Quod cum lupus cognovisset,
ad opilionem accessit,
dolorem socium ei significaturus.
Ergone verum est (inquit)
te tantam fecisse iacturam,
totumque ovium gregem perdidisse?
Heu! quam tui me miseret!
Quantus est dolor meus!
Gratias ago, respondit opilio;
video te
calamitate mea
vehementer commotum.
Semper enim, addit canis,
dolore afficitur lupus,
ubi ex aliorum calamitate
ipse iacturam facit.
