This question is very serious. A little earlier, the article talked about the importance of determining the type of subordinate part. In addition, in this matter, it is necessary to focus on the questions asked, and not on alliances.

The fact is that there is a certain grammatical rule. It is connected with the type of sentence and the use of present/future tense in it.
If a adverbial sentences Answer the questions: "Under what conditions is the action performed?" or "When (when) will this happen?", then they express condition or time respectively. The future tense (with the verb will) is not used in such sentences. The present is used instead. Although the situation clearly points to the future, and it was at this time that it was translated into Russian.
Compare:

• 
  Makes a cake when you arrive - Makes a cake when you arrive.
  
• 
  I will be happy if I get this job.
  

As it is easy to see, in the next case the above example refers to a type - type I subordinate condition. This rule does not apply to the other two types of conditional clauses, because there are completely different constructions to express the grammatical meaning.
In many cases, complex sentences make it possible to better express the speaker's thoughts. Subordinate parts are united by means of special unions. Adverbial time and additional conditions are distinguished as the main varieties.
The English language imposes certain grammatical rules on the use of such structures. To learn them reliably, you need to understand the theory well once, and then do as many exercises as possible so that the correct usage example is cemented in your memory. Later, when necessary, it will automatically appear in the speech.
If ... Past Perfect ..., ... would have + past tense...
or
... would have + past tense... if ... Past Perfect ...

Usage

The third type of conditional sentences in English describe events that could have happened in the past but did not. Note that these sentences are translated into Russian in the subjunctive mood, with the particle "by".
For example:
If you had invited them, they would have come .
If you invited them, they would come . ( But you didn't invite them, so they didn't come. )
If you had worked harder, you would have passed the exam.
If you were more engaged , you would have passed the exam. ( But you didn't study and therefore didn't pass the exam. )
If I had won this award, my life would have changed .
If I won this prize, my life would change .
If he had studied science, he would have found a better job.
If the science he studied , he would have found the best job.
