Simple Sentences

A simple sentence can have one subject and one verb, two subjects and one verb, one subject and two verbs, or two subjects and two verbs. No matter how many subjects and verbs it has, a simple sentence usually needs only a capital letter at the beginning of the sentence and a period at the end.

Example of a simple sentence with one subject and one verb:
Students in manufacturing engineering take a course in manufacturing graphics.

Subject	Verb
Students	take

In a simple sentence with one subject and one verb, the only punctuation is usually a capital letter at the beginning of the sentence and a period at the end.

Example of a simple sentence with two subjects and one verb:
3D CAD and rapid prototyping are taught in the manufacturing graphics course.

Subject 1	Coordinating Conjunction	Subject 2	Verb
3D CAD	and	rapid prototyping	are taught

Two subjects joined by a coordinating conjunction (and, but, or) are called a compound subject. In a simple sentence with a compound subject and one verb, the only punctuation is usually a capital letter at the beginning and a period at the end.

Example of a simple sentence with one subject and two verbs:
Students in the advanced CAD course design and draw mold cavities.

Subject 1	Verb 1	Coordinating Conjunction	Verb 2
Students	design	and	draw

Two verbs joined by a coordinating conjunction (and, but, or) are called a compound verb. In a simple sentence with one subject and a compound verb, the only punctuation in the sentence is usually a capital letter at the beginning and a period at the end.

Example of a simple sentence with two subjects and two verbs:
Heat treated alloys and non-heat treated alloys are tested and evaluated in the metallurgy course.

Subject 1	Coordinating Conjunction	Subject 2	Verb 1	Coordinating Conjunction	Verb 2
heat treated alloys	and	non-heat treated alloys	are tested	and	evaluated

In a simple sentence with a compound subject and a compound verb, the only punctuation in the sentence is usually a capital letter at the beginning and a period at the end.

Exercise: Indicate whether the punctuation in each sentence is correct or incorrect.

1. The course in dimensional metrology, requires an open laboratory.
