Translation of "Pondering" in French

Futurologists have fun pondering about what is to come.

Les futurologues s'amusent à réfléchir à ce qu'il adviendra.

Every now and then I was pondering how to do that

De temps en temps, je me demandais comment le faire

But good AEneas, pondering through the night / distracting thoughts and many an anxious care, / resolved, when daybreak brought the gladsome light, / to search the coast, and back sure tidings bear, / what land was this, what habitants were there, / if man or beast, for, far as the eye could rove, / a wilderness the region seemed, and bare.

Cependant du héros, tandis que tout sommeille, / mille soins inquiets ont prolongé la veille. / Le jour naissant à peine a blanchi les coteaux, / il sort, va visiter ces rivages nouveaux : / sont-ils peuplés d'humains ou de monstres sauvages ?
