GED Language Arts (RLA) Question of the Day

What dire offence from amorous causes springs,

What mighty contests rise from trivial things,

I sing — This verse to Caryl, Muse! is due:

This, even Belinda may vouchsafe to view:

If She inspire, and He approve my lays.

… Sol thro’ white curtains shot a tim’rous ray,

And oped those eyes that must eclipse the day.

Now lapdogs give themselves the rousing shake,

And sleepless lovers just at twelve awake:(10)

Thrice rung the bell, the slipper knock’d the ground,

And the press’d watch return’d a silver sound.

Belinda still her downy pillow prest,

Her guardian Sylph prolong’d the balmy rest.
