The skills of making definite clauses, how to learn definite clauses?

The structure of the definite clause is: definite clause = antecedent word + relative word + clause.

A definite clause, a sentence is modified and qualified after a word or pronoun (antecedent), which is called a definite clause. Generally speaking, a clause is a definite clause in the whole sentence, and this clause is called a definite clause. A clause acts as a definite component in the main clause.

The modified word is called the antecedent. A definite clause is different from a case where a word is used as a definite clause in that it can usually only be placed after the modified word (i.e., the antecedent).

The definite clause is guided by the relative words (relative pronouns, relative adverbs), and the relative pronouns and relative adverbs are located at the beginning of the definite clause.

The difference between a restrictive clause and a non-restrictive clause.

1) From a structural point of view, a restrictive clause cannot be separated from a precedent by a comma; Non-restrictive clauses must be separated by commas. The relative pronouns that lead to non-restrictive clauses cannot be omitted.

For example: the clock, which my great-grandfather bought, is still in good order

This clock was bought by my great-grandfather, and it is still on track.

2) Two adjective clauses often give different meanings to the same antecedent.

For example: My sister who lives in London is a doctor

My sister, who lives in London, is a doctor.

my sister,who lives in london,is a doctor.

My sister is a doctor and she lives in London.

3) Non-restrictive clauses can treat the entire main clause as antecedents, while restrictive clauses do not have this function. When a non-restrictive clause modifies the entire main clause, it can only be guided by which or as.

For example: I said nothing, which made him still more angry

I didn't say a word, which made him even angrier.

he was a frenchman,as i could tell from his accent.

He was French, and I could tell from his accent.

he was drunk,which seemed to make a bad impression on the policeman.

He was drunk, which seemed to make a bad impression on the police.

The structure of the definite clause is: definite clause = antecedent word + relative word + clause.

1. The meaning of the definite clause.

A definite clause is a clause guided by a relative pronoun or a relative adverb, and its function is to modify a certain component of the main clause as a definite clause.

For example: it's the book that I bought yesterday

In this sentence, I bought yesterday, which is guided by that, is a definite clause that is used to modify the book.

2. Two major concepts of definite clauses.

The core content of the definite clause revolves around antecedents and relative words. A correct understanding of antecedents is the key to understanding definite clauses, and the selection and use of relative words is the main content of definite clauses.

1. Antecedents.

The so-called antecedent is the component modified by the definite clause. For example, in the example above, the book is the antecedent of the definite clause. It is important to note that the antecedent can be a word or a phrase or sentence.

2. Relative words.

The definite clause is always connected by a certain relative word, and the relative word mainly plays two major roles in the definite clause, one is to connect the definite clause and the rest of the sentence, and the other is to refer to the antecedent word, which is used as a sentence component in the definite clause.

It should be noted that both relative pronouns and relative adverbs are indispensable because they are intended to act as components in the clause, but relative pronouns are often omitted when they are used as objects in clauses.

Relative pronouns: who, whom (to person) which (to refer to things) that, whose (to refer to people or things).

Relational adverbs: when, where, why
