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:
Harundo aegrē ferēbat, cum cēterae nōn sōlum arborēs, vērumetiam herbae interdum nīdōs avium sustinērent, sē eō honōre prīvārī. Rogāvit ergō aviculam quandam, ut ipsa nīdificāret. Cui illa: facerem, inquit, nisi īnstabilitātī tuae diffīderem. Nōlō enim fīliōrum meōrum domum in fundamentō tam īnstabilī collocātam. Fābula indicat rēs nostrās virīs īnstabilibus minimē committendās.
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):
Harúndo aegre ferébat, cum céterae non solum árbores, verumétiam herbae intérdum nidos ávium sustinérent, se eo honóre privári. Rogávit ergo avículam quandam, ut ipsa nidificáret. Cui illa: fácerem, inquit, nisi instabilitáti tuae diffíderem. Nolo enim filiórum meórum domum in fundaménto tam instábili collocátam. Fábula índicat res nostras viris instabílibus mínime committéndas.
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:
Harundo aegre ferebat,
cum ceterae non solum arbores,
verumetiam herbae interdum
nidos avium sustinerent,
se eo honore privari.
Rogavit ergo aviculam quandam,
ut ipsa nidificaret.
Cui illa: facerem, inquit,
nisi instabilitati tuae diffiderem.
Nolo enim
filiorum meorum domum
in fundamento tam instabili
collocatam.
Fabula indicat
res nostras
viris instabilibus
minime committendas.
