Step 1: Understanding Adverbs of Manner:
Adverbs of manner describe how an action is performed. "Badly" describes the manner in which someone sings. Step 2: Analyzing the Options:
- Badly: This is the correct adverb to describe how someone sings poorly.
- Lately: This refers to something that happened recently, not the manner in which something is done.
- Largely: This means mostly or for the most part, which doesn't fit with the idea of how one sings.
- Orderly: This means in a neat or organized manner, which doesn't fit with the context of singing. Step 3: Conclusion:
The correct adverb is badly.
