Progressive to-infinitive

[kl004535]

Dear teachers,

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.

Thanks

Neither is very natural, most native speakers would say "I fear walking alone at night" or even more likely "I am afraid of walking alone at night".
