Is the following sentence missing semicolons or commas? If so, where?: As I turned around I heard a loud thump the cat had knocked over the goldfish bowl.
Yes, it is missing punctuation.
It needs a comma and a semicolon to separate the sentence and properly punctuate it.
A comma is needed to separate the phrase "as I turned around" from the rest of the sentence. And a semicolon is needed to separate the two independent clauses from each other:
- As I turned around
#color(red),#I heard a loud thump #color(red);#the cat had knocked over the goldfish bowl.
