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:
Rūpe ēditissimā in Agnī tergum dēvolat Aquila. Vidēns id Corvus imitārī, velut Sīmia, gestit Aquilam. In Ariētis vellus sē dimittit, dimissus impedītur, impedītus comprehenditur, comprehēnsus proiicitur pueris. Nōn aliōrum, sed suā sē quisque virtūte aestimet. Tuō tē pede mētīre, inquit Horātius. Id velīs, id tentēs quod possīs.
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):
Rupe editíssima in Agni tergum dévolat Áquila. Videns id Corvus imitári, velut Símia, gestit Áquilam. In Ariétis vellus se dimíttit, dimíssus impedítur, impedítus comprehénditur, comprehénsus proiícitur púeris. Non aliórum, sed sua se quisque virtúte aéstimet. Tuo te pede metíre, inquit Horátius. Id velis, id tentes quod possis.
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:
