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:
Subita aura sustulit crīnēs mentītōs calvī equō vectī. Comitēs rīdent: ipse quoque rīdēns ait; Quid mīrum est sī crīnēs, quī nōn erant meī, abiērunt? Illī enim abierant, quī prius nātūrā meī fuerant.
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):
Súbita aura sústulit crines mentítos calvi equo vecti. Cómites rident: ipse quoque ridens ait; Quid mirum est si crines, qui non erant mei, abiérunt? Illi enim abíerant, qui prius natúra mei fúerant.
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:
Subita aura
sustulit crines mentitos
calvi equo vecti.
Comites rident:
ipse quoque ridens ait;
Quid mirum est
si crines, qui non erant mei,
abierunt?
Illi enim abierant,
qui prius natura mei fuerant.
