Следует отметить, что наличие большого количества At times, the English language does not simplify the process of learning at all and often leads to deep depression not only of students, but of the teachers themselves. Imagine - the teacher explains the difference between the verb in the past simple, long and perfect tenses when they are translated into Russian in exactly the same way!
Essentially, the timing is in English -it is the substitution of the present tense verb in the clause of the sentence with the corresponding form of past tense. This is done if there is a past tense in the main part (see examples). But all verb forms remain unchanged when in the main part the present or future tense. Thus, the table of times can be an indispensable tool for learners and practitioners of the English language. Make it, and it will be useful to you more than once!
I wonder (the present) whether Anna (past) knew about what would happen tomorrow (the future).
In English with literal translation withoutcoordination instead of a clear and intelligible sentence you get a motley and even funny "mess" from the set of words. Compare how two students translated this sentence, one (1) of whom relied on their imaginary knowledge and did not take into account the rules of the English language, and the other (2), not being confident in grammar, used the table of times.
1. I’m interested in what I’m like (Future Simple) tomorrow. (Wrong, read it again, it sounds clumsily to the ear.)
2. I wondered if I knew (Past Simple) the next day. (That's right - read in one breath.)
These simple examples show thatcoordination of tenses in English is a mandatory section in the learning process. And the knowledge of these rules and competent application in English speech will open for you wide boundaries for communication with foreigners.
