Structural-semantic peculiarities of conditional sentences in english and uzbek

You is the subject of the principal clause, expressed by a personal pronoun, second person, plural, Nominative Case.
Home is an adverbial modifier of place, expressed by a common noun.
Anything is the subject of the subordinate clause, expressed by an indefinite pronoun.
Should is a simple verbal predicate, expressed by the verb change ‘to change'' in the analytical form of the Subjunctive Mood with the mood auxiliary ‘should.
Subordinate Adverbial Clauses of Comparison clauses are introduced by the conjunctions “as if” “as though”:

1. 
   Subjunctive Mood in the synthetic form is used if the actions of the principal and the subordinate clauses are simultaneous:
   

He paid no attention to us as if wе didn't exist.

2. 
   Past Perfect is used in the subordinate clause if the action of it precedes that of the principal clause.
   

We faced each other as if we had been having a beer every afternoon for years.
In Subordinate predicative clauses, if the subordinate clause is introduced by the conjunctions “as if” “as though” Past Simple (the verb “ to be” has the form “were” for all the persons) is used if the actions of the principal and the subordinate clauses are simultaneous:
He looked as if he were ill.
b) If the action of the subordinate clause is prior to the action of the principal clause Past Perfect is used.
The house looked as if it had been deserted for years.
The difference between the indicative and the subjunctive mood employed in a conditional sentence exists. The classical example to show this point is the following one:
(1) If Oswald did not kill Kennedy, then someone else did.⁶⁰
(2) If Oswald had not killed Kennedy, then someone else would have.
The first sentence is surely true, because it is a fact that Kennedy was murdered. So, with the hypothesis that the murder is not Oswald, we are forced to assume that another person shot the president. Conversely, the second sentence could very well be false: Oswald was perhaps the only one to shoot. So, the two moods present two different ways to consider a hypothesis. The first one doesn’t erase the consequences of the hypothesis, contrary to the second one.
In my opinion, this difference is considered with a too much importance. In fact, the two moods share a great number of paradoxes.
The paradox of contraposition:
(3) If it were to rain heavily at noon, the farmer would not irrigate his field at noon⁶¹.
(4) If the farmer were to irrigate his field at noon, it would not rain heavily at noon.
(5) If it rains tomorrow, there will not be a terrific cloudburst⁶².
(6) If there is a terrific cloudburst tomorrow, it will not rain.
The paradox of the transitivity:
(7) If Carter had not lost the election in 1980, Reagan would not have been president in 1981⁶³.
(8) If Carter had died in 1979, he would not have lost the election in 1980.
(9) If Carter had died in 1979, Reagan would not have been president in 1981.
(10) If Jones wins the election, Smith will retire⁶⁴.
(11) If Smith dies before the election, Jones will win.
(12) If Smith dies before the election, he will retire.
The paradox of strengthening the antecedent:
(13) If the left engine were to fail, the pilot would make an emergency landing⁶⁵.
(14) If the left engine were to fail and the right wing were to shear off, the pilot would.
In grammar, mood refers to a verb form that shows the writer's attitude toward the content of his or her words. There are three different kinds of mood in English grammar. Nordquist (2018) states that subjunctive mood expresses a desire, a requirement, a suggestion, or a hypothetical⁶⁶. The other two types of mood are indicative and imperative. Indicative mood asks a question or expresses a fact or opinion, while imperative mood is used to issue a command. According to Nordquist (2018), in English grammar, the subjunctive is the mood of a verb expressing wishes, stipulating demands, or making statements contrary to fact. Etymologically, the word subjunctive is from the Latin, "subjoin, bind, subordinate"⁶⁷
According to Sabin (1996) sentences that express necessity, demand, strong request, urging or resolution in the main clause require a subjunctive verb in the dependent clause that follows⁶⁸. For instance, if the verb in the dependent clause requires the use of the verb “to be”, the form “be” must be used for the all the three persons, and not “am”, ‘is” or “are”. Also, if the verb in the dependent clause is a verb other than “be’, one has to use the ordinary present tense form for all three persons without adding the morpheme, “s” to the third person singular (Nordquist, 2019, Sabin, 1996).
Through the work of Deshors and Gries(2019), it has been stressed that in English, the mandative subjunctive serves the specific function of conveying directives⁶⁹ including, for example, commands, orders or requests (Hoffmann 1997), as illustrated in the following construction⁷⁰.
(1) I demand that this be made available to the public again.
As we can see in the above example, similarly to the imperative, the mandative subjunctive, appearing in italics, is formed by using the base form of a verb (e.g. be in our example), and therefore can only be distinguished in the third person singular. Deshors and Gries (2019) assert that syntactically, it tends to occur in object complement clauses (e.g. that this be made available to the public again) following a suasive verb such as demand, order, request or ask among others although the mandative subjunctive can also be used after adjectives and nouns expressing an emotion Also, Hoffmann (1997) and Hundt (2018), among others, have shown that considerable differences exist between how much different main-clause suasive verbs attract mandative subjunctive mood in English⁷¹.
According to Hoffmann (1997), demand, order, and request prefer the mandative subjunctive (some, such as demand, strongly), particularly with a non-inflected subjunctive, whereas propose prefers the modal variant; thus Hoffmann (1997: 26) concludes that “analysing mandative sentences as a unified grammatical phenomenon makes little sense [as the] differences between the individual suasive items are simply too large for such an undertaking”⁷².
Mandative subjunctive expresses a requirement or necessity as well as suggestions (Nordquist, 2018)⁷³. Examples of the subjunctive mood expressing a requirement or necessity that were wrongly constructed by the students are as follows:
Subjunctive mood expressing a requirement or necessity:
