Understanding Independent Clauses and Their Usage in High School English

The Five Basic Sentence Types

There are five basic sentence types in English, and independent clauses are used in many of them. The first type is the declarative sentence, which simply makes a statement. For example, "The dog is sleeping." The second type is the interrogative sentence, which asks a question. For example, "Is the dog sleeping?" The third type is the imperative sentence, which gives a command. For example, "Wake up the dog!" The fourth type is the exclamatory sentence, which shows strong feelings or emotions. For example, "The dog is asleep!" Finally, there is the compound sentence, which is made up of two or more independent clauses connected by a conjunction such as "and," "but," or "or."

Using Independent Clauses to Improve Writing Skills

By understanding how independent clauses work, students can use them to create more complex and effective sentences. For example, instead of simple declarative sentences, students can combine two independent clauses to create a compound sentence. This can add variety and interest to writing, and help convey ideas more clearly and concisely. However, it is important to remember that each independent clause should still express a complete thought and make sense on its own.

The Independent Gerund Phrase

Another way to use independent clauses is through a structure called the independent gerund phrase. This is a phrase that begins with a gerund (a word that ends in "-ing" and functions as a noun) and has a subject and a predicate. For example, "Running marathons is my favorite hobby." The independent gerund phrase adds more information to the sentence and can emphasize a particular action or idea.

Common Errors to Avoid

One common error students make with independent clauses is using them incorrectly in compound sentences. For example, "I went to the store and bought milk, then I went home." This sentence should be separated into two independent clauses, as the words "then I went home" cannot stand alone as a complete sentence. Additionally, it is important to use proper punctuation when connecting independent clauses. Commas should be used before coordinating conjunctions (such as "and," "but," or "or"), and semicolons should be used between two independent clauses without a conjunction.

In conclusion, understanding independent clauses and their usage is essential in high school English classes. With this knowledge, students can improve their writing skills, create more complex sentences, and avoid common errors. By practicing and mastering this important sentence structure, students can achieve success in their English courses and beyond.
