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:
Vir dēcrepitae senectūtis irrīdēbātur ā iuvene quōdam, ut dēlīrus, quod arborēs īnsereret, quārum nōn esset poma vīsūrus. Cui senex: Nec tū, inquit, ex iīs, quās nunc īnserere parās, fructūs fortassē dēcerpēs. Nec mora: Iuvenis ex arbore, quam surculōs dēcerptūrus ascenderat, ruēns collum frēgit. Fābula indicat mortem omnī aetātī esse commūnem.
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):
Vir decrépitae senectútis irridebátur a iúvene quodam, ut delírus, quod árbores inséreret, quarum non esset poma visúrus. Cui senex: Nec tu, inquit, ex iis, quas nunc insérere paras, fructus fortásse decérpes. Nec mora: Iúvenis ex árbore, quam súrculos decerptúrus ascénderat, ruens collum fregit. Fábula índicat mortem omni aetáti esse commúnem.
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:
