Grade 7 comma quiz: compound and complex sentences with answers.

📚 Quick Study Guide

• 🤝 Compound Sentence: Two independent clauses joined by a coordinating conjunction (and, but, or, nor, for, so, yet) and a comma. Example: I wanted to go to the park, but it started to rain.
• 🔗 Complex Sentence: An independent clause and a dependent clause joined by a subordinating conjunction (although, because, if, since, when, etc.) or a relative pronoun (who, which, that). A comma is used if the dependent clause comes before the independent clause. Example: Because it was raining, I stayed home. If the independent clause comes first, a comma is usually not needed. Example: I stayed home because it was raining.
• ✏️ Independent Clause: A clause that can stand alone as a sentence; it has a subject and a verb and expresses a complete thought.
• 🤔 Dependent Clause: A clause that cannot stand alone as a sentence; it starts with a subordinating conjunction or relative pronoun.
• 💡 Comma Rule 1: Use a comma before a coordinating conjunction joining two independent clauses.
• 📝 Comma Rule 2: Use a comma after a dependent clause that begins a sentence.
• ✅ Important Note: If the dependent clause comes after the independent clause, a comma is generally not required unless it adds a nonessential element to the sentence.
