Four sentence types from other bloggers.

Simple: "A "boat" is the main point." (http://thaonguyen85.blogspot.com/)

• In the sentence, there is only one independent clause, so this sentence is a simple sentence.

Complex: "I think this is simple sentence because there is only one complete clause." (http://yjpapaya.blogspot.com/)

• There is only one independent clause and one dependent clause. The subject-verb combanation of the indenpendent clause is "I think"and of the dependent clause is "there is", and the author is trying to use conjunction "because" to explain to the readers, and it makes it a complex sentence.

Compound: "The sentence has only one subject-verb and it is independent clause." (http://chin-yin.blogspot.com/)

• There are two independent clausesm, so this sentence is a compound sentence.

Compound-Complex: "This passage strikes me because it tells when the author caught in the storm and the boat has been hit with the waves that knock him in the water, but he was trying to hold on and fight against the storm to get on the boat." (http://www.tinhsekhongphai.blogspot.com/)

• There are two independent clauses and four dependent clauses, so this sentence is compound-complex. The subject-verb combanation of the independent clauses in this sentence are "passage strikes" and " he was trying", and dependent clauses are "it tells", "author caught", "boat has been hit" and "that knock".
