Classification of Sentences

CLASSIFICATION OF SENTENCES

Understanding the different classifications of sentences based on structure is essential for effective writing and communication. The primary classifications are:

  • Simple

  • Compound

  • Complex

  • Compound-Complex

SIMPLE SENTENCE STRUCTURE

  • A simple sentence consists of one independent clause.

  • Definition of Independent Clause:

    • An independent clause contains a subject and a verb.

    • It expresses a complete thought.

    • It can stand alone and makes sense without adding any other clauses.

EXAMPLES OF SIMPLE SENTENCES

  • Air pollution is an immense issue.

  • Cars release toxic gases.

  • Global warming is an alarming issue.

  • The rate of obesity is increasing rapidly.

  • Air and water pollution are getting worse.

  • The rate of car ownership has gradually grown.

ADVANTAGES OF COMPUTERS IN EDUCATION

  • Convenience is one of the main advantages of using computers in education.

COMPLEX SIMPLE SENTENCES

  • A simple sentence can also have more than one subject or verb:

    • Two subjects:

      • Computers and other technological devices are important in the modern world.

      • Formula: SVSV

    • Two verbs:

      • I search for information and play games on my computer.

      • Formula: SVVSVV

    • Two subjects and two verbs:

      • My brother and I search for information and play games on our computers.

      • Formula: SSVVSSVV

ACTIVITY

  • On a piece of paper, please make some simple sentences about the following topics (2 sentences each):

    • Positive effects of technology

    • Negative effects of technology

COMPOUND SENTENCE STRUCTURE

  • A compound sentence consists of two (or more) independent clauses joined by a comma, conjunction, or semi-colon.

  • Each of these clauses could form a sentence alone.

  • FANBOYS (For, And, Nor, But, Or, Yet, So) are used to join the independent clauses.

EXAMPLES OF COMPOUND SENTENCES

  • Air pollution is an immense issue, but the government is not trying to deal with it.

  • Cars release toxic gases, and factories emit a huge amount of carbon dioxide.

  • Global warming is alarming, so the government has launched a new environmental policy.

  • The rate of obesity is increasing, and people have a sedentary lifestyle.

  • Computers are used widely in most countries; they are a sign of progress.

  • Car ownership has increased dramatically; it has brought so much convenience to our life.

ACTIVITY

  • Take out the piece of paper where you wrote your simple sentences earlier.

  • This time, make some compound sentences by combining your own work with your seatmate's.

    • Example from Student A:

      • The internet allows students to gather information conveniently.

    • Example from Student B:

      • Modern technology has made online interaction possible.

    • Resulting Compound Sentence:

      • Modern technology has made online interaction possible, and the internet allows students to gather information conveniently.

COMPLEX SENTENCE STRUCTURE

  • A complex sentence consists of an independent clause plus a dependent clause.

  • Definition of Dependent Clause:

    • A dependent clause starts with a subordinating conjunction or a relative pronoun, such as that, which, who, whom, whose.

    • It contains a subject and a verb but does not express a complete thought.

COMMON SUBORDINATING CONJUNCTIONS

  • That

  • Which

  • Who

  • Whom

  • Whose

EXAMPLES OF COMPLEX SENTENCES

  • Capital cities where numerous automobiles are utilized tend to be more polluted than rural areas.

  • If the government constructs comfortable and affordable public transportation systems, the rate of car ownership will automatically drop.

  • Industrial factories that are often located near the bodies of water are considered agents of pollution.

  • Even though technology has become more advanced than before, interaction between family members is less nowadays.

  • In order to address air pollution, the government must impose stringent laws against environmentally hazardous factories.

  • People take natural health supplements even though they may not have been tested.

  • I went to bed as soon as he left because I was tired.

ADVERBIAL CLAUSES

  • In the aforementioned complex sentences, the second clause can be used to start the sentence.

  • In this case, a comma is needed in the middle:

    • Even though they may not have been tested, people take natural health supplements.

    • As soon as he left, I went to bed because I was tired.

ACTIVITY

  • Rewrite the compound sentences you made earlier by changing the conjunction or the order of the clauses. You can also make new complex sentences.

    • Formula: Independent + Subordinating Conjunction + Dependent.

    • Example: One of the main positive effects of technology is convenience; however, it leads to a passive lifestyle.

    • Formula: Subordinating Conjunction + Dependent Clause, Independent Clause.

COMPOUND-COMPLEX SENTENCE STRUCTURE

  • A compound-complex sentence consists of at least two independent clauses and one or more dependent clauses.

STRUCTURAL DIAGRAM

  • Independent

  • Subordinating Conjunction

  • Dependent

  • Coordinating Independent Conjunction

EXAMPLES OF COMPOUND-COMPLEX SENTENCES

  • Although the government is trying to deal with pollution, they still need to exert more effort, and people must also help in solving this problem.

  • If the government constructs a comfortable and affordable public transportation system, the rate of car ownership will automatically drop, and the amount of carbon dioxide production will also decrease.

  • Industrial factories that are often located near the bodies of water are considered agents of pollution because they release toxic waste into the water.

  • In order to address air pollution, the government must impose stringent laws against environmentally hazardous factories for the conservation of the environment.

IDENTIFICATION OF SENTENCE TYPES

  • Identify the following sentences:

    • a. simple

    • b. compound

    • c. complex

    • d. compound-complex

    • 1. Even though pollution is widespread, people are doing little to prevent it. C

    • b. What can be done to reduce the production of carbon dioxide?

    • c. Why do many students go abroad to study English?

IMPORTANT NOTE

  • The tense of the verb doesn’t affect the sentence structure.

  • Whether using simple present tense or present perfect, if you only have an independent clause, it is still a simple sentence.

  • However, using different tenses correctly gives your essay a better elaboration.

PASSIVE SENTENCES

  • Although technology is used on a daily basis, people must still not depend on it because it can also be harmful.
