Final answer:
The sentences provided are classified as simple, complex, and compound, based on the number of main and dependent clauses. The parts of speech identified include nouns, adjectives, verbs, and adverbs. Adjustments in comma placement have been suggested for the review sentences.
Step-by-step explanation:
When determining whether a sentence is simple, compound, or complex, it is crucial to look at the number of independent and dependent clauses it contains. Let's analyze each sentence individually:
- I took the dog for a half-mile walk - This is a simple sentence because it contains one main clause with a single subject and verb.
- The dog ran cheerfully through the park because he had been shut in the house all day - This is a complex sentence because it has one main clause and a dependent clause introduced by the subordinating conjunction 'because'.
- He stopped to smell several flowers, and he chased a squirrel - This is a compound sentence because it consists of two main clauses connected by the coordinating conjunction 'and'.
