Answer:
The sentence you provided is a simple sentence. It consists of one independent clause, which expresses a complete thought. To expand on this sentence using compound, complex, and compound-complex sentences, let's start with the original sentence:
Original Simple Sentence:
"The weather is lovely."
Compound Sentence:
"The weather is lovely, and we should go for a walk."
In this compound sentence, two independent clauses, "The weather is lovely" and "we should go for a walk," are joined by the coordinating conjunction "and."
Complex Sentence:
"Although the weather is lovely, I have to finish my work."
This is a complex sentence with one independent clause, "I have to finish my work," and one dependent clause, "Although the weather is lovely." The dependent clause cannot stand alone as a complete thought.
Compound-Complex Sentence:
"The weather is lovely, so I want to go for a walk, but I have to finish my work first."
This is a compound-complex sentence with two independent clauses, "The weather is lovely" and "I want to go for a walk," joined by the coordinating conjunction "so." Additionally, it includes a dependent clause, "but I have to finish my work first."
Compound Sentence:
"The weather is lovely, but some people prefer staying indoors."
In this compound sentence, two independent clauses, "The weather is lovely" and "some people prefer staying indoors," are joined by the coordinating conjunction "but."
Complex Sentence:
"While the weather is lovely, others might not appreciate it."
This complex sentence contains one independent clause, "others might not appreciate it," and a dependent clause, "While the weather is lovely," which provides context but cannot stand alone as a complete thought.
These examples illustrate how you can vary the structure of sentences to convey different levels of complexity and meaning.
