To understand grammatical sentence structure, it is necessary to find its basis first of all. For this purpose use the methods developed by linguists. When understanding a basis of the offer you will be able correctly to place punctuation marks, for example.
Instruction
1. Learn that the grammatical basis represents. These are the principal parts of the sentence - a subject and a predicate which usually and make the main meaning of the offer. In certain cases offers may contain only a subject or only a predicate and also several words performing identical functions of the principal parts of the sentence.
2. Find a subject. Most often it is expressed by a noun or a pronoun. In this case it surely costs in the Nominative case and answers the question "who?" or "what?". In an exceptional case the role of an object or the subject of action in the offer plays a numeral or even the whole phrase. If you see in the offer a proper name in the Nominative case, it is very probable that it will be a subject.
3. Define a predicate in the offer. It designates action of a subject which is a subject. In the majority of offers the predicate is the verb coordinated with a subject in number and a sort. Also this sentence part can be expressed by verbal phrases, verbal adjectives and even nouns. The verb has to answer the question "who does?" or "what does?", grammatical coordinated with the first part of a basis of the offer.
4. Note the found basis in the offer. Emphasize a subject with one continuous horizontal line, and a predicate - two.
5. If subjects and predicates it is several, specify grammatical sentence structure. If all subjects and predicates are coordinated with each other grammatical and on sense, then it indicates a simple sentence. On the contrary, if they are independent and have independent value, then before you offers with two or more bases between which there is a coordinating or subordinative communication.
