What should one look for at the sentence level according to the content provided?

At the sentence level, an important focus is on parts of speech usage and structure. This involves evaluating how different types of words—such as nouns, verbs, adjectives, and adverbs—function within sentences to create clear meaning and grammatical correctness. Understanding the role each part of speech plays helps in constructing effective sentences and allows for better comprehension of the language and its rules.

This focus on parts of speech and grammatical structure aids in developing a strong foundation for English language learners. It enables them to not only recognize the components of sentences but also to understand how these components interact, which is crucial for both writing and comprehension. Therefore, examining parts of speech usage is essential for effective communication and language development.
