For general sense, I would say
1. I fear to walk alone at night.
and it will do.
However, in my grammar book, it states :
2. I fear to be walking alone at night.
I know it is progressive to-infinitive, but I do not know what it wants to highlight.
Does it mean that it wants to highlight the walking duration rather than the action expressed by "walk" ?
Please elucidate the difference to me.
I am much obliged to you for your guidance.
