Answer:
1. Thrilled
2. Filled
3. Beating
4. Repeating
Explanation:
And the silken, sad, uncertain rustling of each purple curtain
<u>Thrilled</u> me-<u>filled</u> me with fantastic terrors never felt <em><u>before</u></em>;
So that now, to still the <u>beating</u> of my heart, I stood <u>repeating</u>,
"'Tis some visitor <em>entreating entrance</em> at my chamber door-
Some late visitor <em>entreating entrance</em> at my chamber door;-
This it is and nothing <em><u>more</u></em>."
I hope this helps you in any shape or form.
