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:
Columbae milvī metū accipitrem rogāvērunt, ut eās dēfenderet. Ille annuit. At in columbāre receptus, ūnō diē māiōrem strāgem ēdidit, quam milvus longō tempore potuisset ēdere. Fābula docet malōrum pātrocinium vītandum esse.
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):
Colúmbae milvi metu accípitrem rogavérunt, ut eas defénderet. Ille ánnuit. At in columbáre recéptus, uno die maiórem stragem édidit, quam milvus longo témpore potuísset édere. Fábula docet malórum patrocínium vitándum esse.
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:
Columbae
milvi metu
accipitrem rogaverunt,
ut eas defenderet.
Ille annuit.
At in columbare receptus,
uno die
maiorem stragem edidit,
quam milvus
longo tempore
potuisset edere.
Fabula docet
malorum patrocinium
vitandum esse.
