Compound sentence –
this is a complex sentence, parts
which are connected
coordinating conjunctions and
grammatically independent friend
from each other, that is, they are in
relations of equality,
equivalence.
THE TRANSPARENT FOREST ONE TURNES BLACK, AND
THE FIR IS GREEN THROUGH THE FROST, AND THE RIVER
IT SHINES UNDER THE ICE.

Complex sentence
this is called a complex sentence, parts
which are interconnected by subordinates
conjunctions (or allied words) and are in
relations of formal inequality.
Example: . I don't want the world to recognize my mysterious
story. (M. Lermontov)
The first part is the main part, and the second part is
dependent (called subordinate clause).
The dependence of the second on the first part is formally
is revealed in the very possibility of logical
question from main to dependent. Associated parts with
using the subordinating conjunction so.

NON-UNION COMPLEX SENTENCE –
THIS IS A COMPLEX SENTENCE, PARTS
WHICH ARE CONNECTED IN MEANING AND
INTONATIONS.

Material used

Complex sentences with different types of connections- This complex sentences , which consist of at least out of three simple sentences , interconnected by coordinating, subordinating and non-union connection.

To understand the meaning of such complex structures It is important to understand how the simple sentences included in them are grouped together.

Often complex sentences with different types of connections are divided into two or several parts (blocks), connected using coordinating conjunctions or without unions; and each part in structure is either a complex sentence or a simple one.

For example:

1) [Sad I]: [there is no friend with me], (with whom I would drink the long separation), (whom I could shake hands from the heart and wish many happy years)(A. Pushkin).

This is a complex sentence with different types of connections: non-union and subordinating, consists of two parts (blocks) connected non-union; the second part reveals the reason for what is said in the first; Part I is a simple sentence in structure; Part II is a complex sentence with two attributive clauses, with homogeneous subordination.

2) [Lane was all in the gardens], and [grew at the fences linden trees, now casting, under the moon, a wide shadow], (so fences And gates on one side they were completely buried in darkness)(A. Chekhov).

This is a complex sentence with different types of connections: coordinating and subordinating, consists of two parts connected by a coordinating conjunction and, the relations between the parts are enumerative; Part I is a simple sentence in structure; Part II - a complex sentence with a subordinate clause; the subordinate clause depends on the main thing and is joined to it by the conjunction so.

A complex sentence can contain sentences with different types of conjunction and non-conjunction connections.

These include:

1) composition and submission.

For example: The sun set and night followed day without interval, as is usually the case in the south.(Lermontov).

(And is a coordinating conjunction, as is a subordinating conjunction.)

The outline of this proposal:

2) composition and non-union communication.

For example: The sun had long since set, but the forest had not yet died down: turtle doves were murmuring nearby, a cuckoo was crowing in the distance.(Bunin).

(But - coordinating conjunction.)

The outline of this proposal:

3) subordination and non-union connection.

For example: When he woke up, the sun was already rising; the mound obscured him(Chekhov).

(When - subordinating conjunction.)

The outline of this proposal:

4) composition, subordination and non-union connection.

For example: The garden was spacious and there were only oak trees; they began to bloom only recently, so that now through the young foliage the entire garden with its stage, tables and swings was visible.

(And is a coordinating conjunction, so that is a subordinating conjunction.)

The outline of this proposal:

In complex sentences with coordinating and subordinating conjunctions, coordinating and subordinating conjunctions may appear side by side.

For example: The weather was beautiful all day, but as we approached Odessa, it began to rain heavily.

(But - a coordinating conjunction, when - a subordinating conjunction.)

The outline of this proposal:

Punctuation marks in sentences with different types of communication

In order to correctly place punctuation marks in complex sentences with different types of connections, it is necessary to select simple sentences, determine the type of connection between them and select the appropriate punctuation mark.

As a rule, a comma is placed between simple sentences in complex sentences with different types of connections.

For example: [In the morning, in the sun, the trees were covered with luxurious frost] , and [this went on for two hours] , [then the frost disappeared] , [the sun has closed] , and [the day passed quietly, thoughtfully , with a drop in the middle of the day and anomalous lunar twilight in the evening].

Sometimes two, three or more simple offers most closely related to each other in meaning and can be separated from other parts of a complex sentence semicolon . Most often, a semicolon is in place of the demon union communications.

For example: (When he woke up), [the sun had already risen] ; [the mound obscured it].(The sentence is complex, with different types of connections: with non-union and union connections.)

At the site of the non-union connection between simple sentences within a complex possible Also comma , dash And colon , which are placed according to the rules for placing punctuation marks in a non-union complex sentence.

For example: [The sun has long since set] , But[the forest has not yet died down] : [doves gurgled nearby] , [the cuckoo crowed in the distance]. (The sentence is complex, with different types of connections: with non-union and union connections.)

[Leo Tolstoy saw a broken burdock] – and [lightning flashes] : [the idea of an amazing story about Hadji Murad appeared](Paust.). (The sentence is complex, with different types of connections: coordinating and non-conjunctive.)

In complex syntactic constructions that break up into large logical-syntactic blocks, which themselves are complex sentences or in which one of the blocks turns out to be a complex sentence, punctuation marks are placed at the junction of the blocks, indicating the relationship of the blocks, while maintaining the internal signs placed on their own syntactic basis.

For example: [The bushes, trees, even stumps are so familiar to me here] (that wild felling has become like a garden to me) : [I caressed every bush, every pine tree, and Christmas tree], and [they all became mine], and [it’s the same as if I planted them], [this is mine own garden] (Priv.) – there is a colon at the junction of blocks; [Yesterday a woodcock stuck his nose into this foliage] (to get a worm from under it) ; [at this time we approached], and [he was forced to take off without throwing off the layer of old aspen foliage from his beak](Priv.) – there is a semicolon at the junction of blocks.

Particular difficulties arise placement of punctuation marks at the junction of the composing And subordinating conjunctions (or coordinating conjunction and allied word). Their punctuation is subject to the laws of the design of sentences with coordinating, subordinating and non-conjunctive connections. However, there are also special attention require sentences in which several conjunctions appear nearby.

In such cases, a comma is placed between conjunctions if the second part of the double conjunction does not follow. then, yes, but(in this case subordinate clause may be omitted). In other cases, a comma is not placed between two conjunctions.

For example: Winter was coming and , When the first frosts hit, living in the forest became difficult. - Winter was approaching, and when the first frosts hit, it became difficult to live in the forest.

You can call me, but , If you don't call today, we'll leave tomorrow. – You can call me, but if you don’t call today, then we’ll leave tomorrow.

I think that , if you try, you will succeed. – I think that if you try, you will succeed.

Syntactic analysis of a complex sentence with different types of connection

Scheme for parsing a complex sentence with different types of connection

1. Determine the type of sentence according to the purpose of the statement (narrative, interrogative, incentive).

2. Indicate the type of sentence based on emotional coloring (exclamatory or non-exclamatory).

3. Determine (based on grammatical basics) the number of simple sentences and find their boundaries.

4. Determine the semantic parts (blocks) and the type of connection between them (non-union or coordinating).

5. Give a description of each part (block) by structure (simple or complex sentence).

6. Create a proposal outline.

Complex sentences with different types of connections- This complex sentences , which consist of at least from three simple proposals , interconnected by coordinating, subordinating and non-union connections.

To understand the meaning of such complex constructions, it is important to understand how the simple sentences included in them are grouped together.

For example:

1) [Sad I]: [there is no friend with me], (with whom I would drink the long separation), (whom I could shake hands from the heart and wish many happy years)(A. Pushkin).

Punctuation marks in sentences with different types of communication

As a rule, a comma is placed between simple sentences in complex sentences with different types of connections.

For example: (When he woke up), [the sun had already risen] ; [the mound obscured it].(The sentence is complex, with different types of connections: with non-union and union connections.)

For example: [The bushes, trees, even stumps are so familiar to me here] (that wild felling has become like a garden to me) : [I caressed every bush, every pine tree, every Christmas tree], and [they all became mine], and [it’s the same as if I planted them], [this is my own garden](Priv.) – there is a colon at the junction of blocks; [Yesterday a woodcock stuck his nose into this foliage] (to get a worm from under it) ; [at this time we approached], and [he was forced to take off without throwing off the layer of old aspen foliage from his beak](Priv.) – there is a semicolon at the junction of blocks.

Particular difficulties arise placement of punctuation marks at the junction of the composing And subordinating conjunctions (or coordinating conjunction and allied word). Their punctuation is subject to the laws of the design of sentences with coordinating, subordinating and non-conjunctive connections. However, at the same time, sentences in which several conjunctions appear nearby stand out and require special attention.

In such cases, a comma is placed between conjunctions if the second part of the double conjunction does not follow. then, yes, but(in this case the subordinate clause may be omitted). In other cases, a comma is not placed between two conjunctions.
