See your other post. I'll be happy to check your work once you study that webpage and state what YOU THINK the adverbs, etc., are.

To answer the question, "What is the common feature in these sentences?":

The common feature in these sentences is the use of adverbs. Adverbs are words that modify verbs, adjectives, or other adverbs. They add information about how, when, where, or to what extent an action is performed.

In these sentences, we can see various adverbs being used:

1. She never spoke a word. (Adverb: never)
2. The apples are rather cheap. (Adverb: rather)
3. I kept my shoes outside. (Adverb: outside)
4. The lion roared loudly. (Adverb: loudly)
5. We will play football today. (Adverb: today)
6. How often does he call you? (Adverb: often)
7. The old woman spoke softly. (Adverb: softly)
8. I have never watched any movie in a theater. (Adverb: never)
9. It's very cold. (Adverb: very)
10. I often meet her at the library. (Adverb: often)

Adverbs are important in providing extra information and adding detail to a sentence. To identify adverbs in a sentence, you can ask yourself questions like:

- How? (loudly, softly)
- When? (today, often, never)
- Where? (outside, in a theater)
- To what extent? (very, rather)

By analyzing the sentences and looking for these types of words, you can identify the adverbs and understand how they enhance the meaning of the sentence.
