Hello Grammar Exchange members!
I ran into the following sentences while reading an essay titled "Field Trip" by Naomi Shihab Nye.
(a) She shook her head. “I guess none of those cute kids will ever become printers now, will they? Gee, I hope they don’t stop reading and writing! Andto think of it happening in front of such an interested audience! Oh, I feel just terrible about it.”
The underlined phrase is not a complete sentence and also I guess the phrase is used to express a suprise. Is there a usage that an infinitive phrase is used to express an exclamation?
I'm also wondering how "it" and "happening" are right behind a prepostion "of" like the underlined phrase. I think "happening" is a gerund because of the preposition "of" but I don't understand how "it" can be in front of "happening" like that. I guess "it" is a subject of "happening" semantically but I don't know my reasoning is right.
Thanks in advance!
