I m a second year junior high school student, can you talk about the tense of the main clause clause

This should be divided into real and virtual tenses.

You can check it on the website.

The most direct way to buy a book to read, or ask the teacher directly, to put it simply, the second year of junior high school should be: use the present tense if it happens now. The content of the clause takes place in the past tense or the past perfect tense before the main clause.

The consistent relationship between the main clause and the subordinate clause in the main and subordinate compound sentences.

1) In the object clause, the tense between the main clause and the clause is consistent, and the tense of the clause predicate is usually determined by the tense of the subject clause predicate.

a.If the subject clause predicate verb is in the present or future tense, such as: simple present tense, present perfect tense, simple future tense, future perfect tense, etc., the clause can use any tense as you need.

b.If the subject clause predicate verb is in the past tense (simple past tense, past continuous tense, past perfect tense, past future tense, past future perfect tense), the clause predicate verb must also be in the past tense.

a.If the clause action occurs at the same time as the main clause action, the clause is in the simple past tense or past continuous tense.

b.When the clause action occurs before the main clause action, the clause is to be completed with the past.

c.When the clause action occurs after the main clause action, the clause should be in the past future tense.

c.When a clause denotes an objective thing or truth, or a truth that people have already accepted, its tense is not affected by the tense of the predicate verb of the main clause. Even though the subject clause predicate verb uses some tense in the past tense, the tense of the clause is still some tense in the present.

d.When a clause indicates a wish that has not arisen or has not yet been fulfilled, the past tense must be used.

e.Some adjectives can be followed by clauses, which can generally be regarded as object clauses, and their predicates should also be consistent with the tense of the subject clause predicate. Adjectives that can be used with this kind of object clause are:

Afraid, glad, sure, confident, sorry, certain, conscious, aware, etc. The principle of consistency is the same as that of an object clause.

Simple present tense.

Dear: I wish you progress in your studies and have fun every day!

The clause tense should be so, present.

The conditional adverbial clause tense is as follows.

1, the subject will be from the present, the main clause is in the simple future tense, and the clause is in the simple present tense 2, the subject is from the past, when the predicate verb of the main clause is in the past tense, the clause must be used to indicate a certain tense of the past.

3, The main present is never limited, the tense of the main clause is the simple present tense, the present continuous tense, the present perfect tense and other tenses, and the following clause tense is not limited by the main clause, and the future tense can be used or the past tense.

The main clause is in the simple present tense, the clause is added in the simple present tense, the present continuous tense, the present perfect tense, and the simple future tense.
