The definite clause is explained simply, and the example sentence of the definite clause is simple

The definite clause is equal to the postposition, and after the noun pronoun it wants to modify, the antecedent is the main component, and here it is the "book".

In fact, many of the adjectives in English are at the back, book of interest, books of interest.

book which he is interested in the book he is interested in.

The above two sentences are both predicatives for book, but one is a simple prescript, and the other is a definite clause, but the position is the same.

These are the books he wrote when he was young: this is the book (which) he wrote when he was young

The definite sentence is generally "·· The form of "is mostly an adjective or an adjective phrase or an adjective sentence.

In sentences like the one you caught, the book is the antecedent, and the adjective phrase he wrote when he was younger. Translated as this, these are the books he wrote when he was young.

Hope, thank you.

To translate a sentence, it is necessary to first analyze the sentence, first analyze the sentence "These are the books he wrote when he was young".

First of all, the trunk is: these are books. Re-analysis, when the book was, it can be seen that "he wrote it when he was young" is a temporal adverbial clause, indicating the time when these books were written.

The translation goes something like this: these books were writen when he was youngor "these were books that were writen when he was young".

The first of these two translations is more concise and focuses on the adverbial clause, and the second sentence uses the definite clause and the adverbial clause. But I personally think that this question is for you to translate the adverbial clause rather than the definite clause.

these book which he wrote at his young age.The antecedent must be the book, because the book is the central language, and what was written when you were young is used to modify the book, that is, it is used to describe the book. Which can also be replaced by that, in which, and relative pronouns can also be omitted.

I think you can't tell who is the antecedent. Nouns preceded by "of" are all antecedents.

The example sentence of the definite clause is simply as follows:

1. Who refers to the person as the subject in the clause.

1）the boys who are playing football are from class one.The boys who play soccer are in the same class.

2）yesterday i helped an old man who lost his way.Yesterday, I helped an old man who was lost.

2. WHOM refers to a person, which acts as an object in the definite clause and can often be omitted.

1）mr. liu is the person（whom）you talked with on the bus.Mr. Liu is the one who chatted with you on the bus.

2）mr. ling is just the boy whom i want to see.Mr. Ling happens to be the boy I want to meet.

3）the man who/whom you met just now is my friend.The man you just met was my friend.

Note: The relative pronoun whom is often replaced by who in colloquial and informal language and can be omitted.

3. Which refers to the object, which is the subject or object in the definite clause, and can be omitted when the object is used.

1）football is a game which is liked by most boys.Football is a game that most boys enjoy.

2）this is the pen（which）he bought yesterday.This is the fountain pen he just bought yesterday. Accompaniment.

4. When that refers to a person, the clan bucket is equivalent to who or whom; When referring to things, it is equivalent to which.

In the definite clause as the subject or object, it can be omitted when the object is made.

1）the number of the people that/who come to visit the city each year rises one million.

2）where is the man that/whom i saw this morning?

5. Whose usually refers to people, but also refers to things, and is used as a definite clause in a definite clause.

1) he has a friend whose father is a doctor.

2) i once lived in a house whose roof has fallen in.
