Two-part sentences are simple sentences based on both the subject and the predicate. As a rule, both main members agree with each other in gender, number and person, for example: The young man laughed. - The girl laughed. – Children laughed.
If simple two-part sentences have only main members, then they are non-common: The sun was setting. And if other members of the sentence are included in them, complementing and revealing the meaning of what was said, then they are common: The shining sun was setting over the horizon.
Two-part sentences. Subject
Subject is one of the main members of a sentence, which is usually expressed by a noun, pronoun or any part of speech used in the meaning of a noun. Acting as the subject, they are in the nominative case and are connected grammatically and in meaning with the predicate: 1) Clouds floated in the sky. 2) We had a lot of fun. 3) The adults were sitting at the table. 4) The audience listened to the report.
Two-part sentences can also have a verb in the indefinite form or a numeral as a subject. These parts of speech areIn this case, they do not acquire the meaning of a noun, but turn into the main member of the sentence, because they answer the question "what?" and the predicate applies to them: I wanted to drive the ball until the evening. (What did you want? - Drive (the ball)). It's very easy to ask about it. (What is simple? - Ask). Note that if you change the word order in these sentences, they will become impersonal.
Predicate
Besides the subject, a two-part sentence has one more main member - a predicate, denoting the action or the state in which the person or object indicated by the subject is located. The main role in the predicative connection between the subject and the predicate belongs to the predicate. It should be clarified that this connection is based on the form of words, their order, intonation connection and the presence of function words: I will tell the whole truth. There are people who think differently.(Form of words).
Distinguish between simple and compound predicates. Please note that the forms of the future tense: I will sing, I will read, etc. - are considered a simple predicate, unlike compound ones, in which there is a linking verb "was" and a semantic word: He was cheerful.
The predicative connection is especially pronounced with the help of intonation, in the case when the predicate is a noun or a full adjective: Paris is the capital of fashion. Spring is sunny, early. In scientific speech, at the place of this intonational pause, the word is often used: Hydrogen is gas.
Two-part sentences. Examples of dashes between subject and predicate
As a missing link between subject and predicate expressednouns in the nominative case, put a dash: the Moon is a satellite of the Earth. Hyacinth is a beautiful flower.
If the predicate has a negative particle "not", then the dash is not put: Laughter is not a sin.
Also, dashes are put in sentences with subject and predicate in the indefinite form of the verb: Fly - soar above the clouds. Before the words: "this", "here", "this means", etc., before the predicate, a dash is also necessary: Starting work now means not finishing it before nightfall.
