Advice 1: As nouns the sentence

A noun is a separate part of speech. It answers the questions who? or what? and denotes an object. Noun maybe almost any part of the sentence: as the main – subject or predicate, and minor – addition, a determination or circumstance.
Noun - a unique part of speech

A noun in the role of the main parts of the sentence

The main members in proposal or base are the subject and predicate. They are closely related to each other. The subject answers the questions of the nominative case: who or what. For example: "Come (what?) the autumn". "Students (who?) prepared for the lesson." Often the subject is expressed by a noun in the nominative case. "Gusto went (what?) snow."

The predicate is the second main part of the sentence, which usually is associated with a subject and answers the questions: what is the subject doing what he's doing, who he is, what is it? Predicates can be simple verbal and compound.
Composite nominal predicate usually consists of a verb-bundles and a nominal part, which expresses the main lexical meaning of the predicate.

In a compound nominal predicate with nominal part can also be expressed as a noun. For example: "She's my sister." "She was my sister." In the first sentence, the noun "sister" is in the nominative case and is the predicate, and in the second sentence, the noun in instrumental case "sister" is nominal part of compound predicate "was sister."

The predicate may be a noun with a preposition or without, standing in the oblique case. For example: "It broke". Here, "without a penny" - predicate. It can also be the whole phrase in which the main word is a noun in the genitive (meaning qualitative assessment). For example: "the boy tall". In this sentence the phrase "tall" is the predicate.

Secondary parts of the sentence expressed by a noun

Words explaining in the proposal the principal and other members, is called a minor sentence. According to the grammatical values of allocate Supplement, definition and circumstance.

Most often the noun in the sentence is a complement. It is a minor member, indicating the subject and answering the questions of indirect cases. For example: "Even in school I chose (what?) profession." The noun "profession" in this sentence is in the accusative case and is the Supplement.

It can also be expressed using an integral phrase which included nouns in oblique cases. For example: "On a winter vacation Masha went to the grandparents". Here the phrase "grandparents" - Supplement.
A special kind of determination – the application is always expressed by a noun, which is in the same case that defined the word. For example: "On the threshold appeared the watchman-the old man." The noun "man" application.

Another minor part of the sentence – definition, labeling the features of the subject, answers the questions: what and whose? It can also be expressed syntactically a noun or a whole noun phrase (noun and adjective). For example: "Hunting (what?) with the dog beautiful." The noun "dog" in this sentence is the definition. Or: "In walked a woman (what?) high growth." Here as the definition stands indivisible phrase "high growth."

The fact answers the questions: how, why, when, and why? It explains a verb or other sentence, and denotes the sign of the action or any other sign. It can also be a noun. For example: "Mary (?) with curiosity considered the book". "Three girls under the window spun (when?) late in the evening". "Joy (why?) she clapped her hands".

Advice 2 : What is the subject

The subject is one of the two main parts of the sentence. A word or a few words at this role point to the object, to which we report. A subject can be allocated in a simple sentence, main and subordinate parts of a complex and sometimes in predicative structures, which are formed of non-personal forms of the verb.
What is the subject
The subject may be expressed by different parts of speech. This is usually a noun in the nominative or its equivalent – personal, relative, indefinite, interrogative and negative pronouns. Also subject can be a numeral, a proper noun and even a verb (indefinite form).
The composition of this part of the sentence in the Russian language is not always limited to one word. Sometimes the subject is represented syntactically or lexically indivisible phrase. These may be catch phrases, compound names of institutions and geographical names, idioms. Nouns denoting quantity, can play the role of subject, if combined with a noun in the genitive case (many people). Numbers "how many", "few", "many" should also be combined with a noun in the genitive case, and indefinite pronouns with adjectives.
May become subject design, consisting of a noun or personal pronoun in the nominative case, the preposition "with" and a noun in the instrumental case. Another such scheme is an adjective, pronoun or numeral in the nominative case along with the preposition "of" and a noun or pronoun in the genitive case.
A definite answer to the question of whether the subject hierarchical top offers, does not exist. Grammatist, for example, claimed subject top, because it, unlike the predicate refers to an entity. Other researchers have proposed to identify dominant supply, removing grammatically dependent. The result of this analysis, the core of the sentence becomes the predicate, and the subject falls into one category with other nominal parts of a sentence that depend on the predicate (actants).
However, the function to be differentiated from other nominal parts of the sentence. Typical features include its Autonomous subject or unmarked form of the name (in Indo-European languages the nominative case), a particular syntactic position, consistent with the predicate, autonomy references correlation with reflexive pronouns, the omission in subsequent predicates of the presumption of the existence of the designated object, the ability to be the subject of the participial turnover (in Russian).
The presence of this member of the sentence is not always necessary. In cases where it is not, the object can be determined from the context.
