I have to identify the adverb and the word or words the adverb modifies.

1.Some kinds of opals are extremely beautiful.
2.The ocean appears especially beautiful at sunrise.
3.On Sunday, the dogs in my neighborhood barked early.
4.No room remained at the end of the row, so everyone moved over.

1.extremely=beautiful
2.especially=beautiful
3.early=barked
4.over=moved

You are PERFECTLY correct!

To identify the adverb and the word or words it modifies, you can follow these steps:

1. Identify the adverb: An adverb is a word that modifies a verb, adjective, or another adverb. It often answers questions such as "How?", "When?", "Where?", "To what extent?", etc.

2. Determine the word or words the adverb modifies: The adverb usually provides additional information about the verb, adjective, or adverb it modifies.

Now, let's apply these steps to the given sentences:

1. "Some kinds of opals are extremely beautiful."
- Adverb: extremely
- Word modified: beautiful
Therefore, the adverb "extremely" modifies the adjective "beautiful."

2. "The ocean appears especially beautiful at sunrise."
- Adverb: especially
- Word modified: beautiful
Hence, the adverb "especially" modifies the adjective "beautiful."

3. "On Sunday, the dogs in my neighborhood barked early."
- Adverb: early
- Word modified: barked
In this case, the adverb "early" modifies the verb "barked."

4. "No room remained at the end of the row, so everyone moved over."
- Adverb: over
- Word modified: moved
Thus, the adverb "over" modifies the verb "moved."

By following these steps, you can accurately identify the adverb and the word it modifies in a sentence.
