A simple sentence is modified and defined after a noun or pronoun (called antecedent), which is called an attributive clause. As the attribute in the main component. [1] the modified word is called antecedent. An attributive clause differs from a word in that it is usually placed only after the modified word (the antecedent).

Attributive clauses are guided by relative words (relative pronouns and relative adverbs). Relative pronouns and relative adverbs are located at the beginning of attributive clauses.

The attributive clause guided by relative pronoun

The antecedent of a relative pronoun is the noun or pronoun of a person or thing, and acts as the subject, object, attribute and so on in the sentence. When the relative pronoun is used as the subject in the attributive clause, the person and the number of the subordinate predicate verb should be consistent with the antecedent.

1) who, whom, that

The antecedent of these words is the noun or pronoun of a person, and plays a role in the clause:

Is, he, the, man, who/that, wants, to, see, you?

Is he the one who wants to see you? (who/that is the subject in the clause) He, is, the, man, whom/, that, I, saw, yesterday.

He is the man whom I saw yesterday. (whom/that is the object in the clause)

2) Whose is used to refer to people or things (used only as attributes, and if they refer to objects, they can also be interchanged with of which), for example:

They rushed over to help the down. man whose car had broken, the man car broke down, everyone rushed to help.

Please, pass, me, the, book, whose (of, which) cover is green., please pass me that book with green paper.

3) which, that

The antecedent they replace is the noun or pronoun of a thing, and can be used as the subject, object, etc. in the clause, for example:

A prosperity which / that had never been seen before appears in the countryside. rural unprecedented prosperity. (which / that is the subject in the sentence)

The package which / that you are carrying unwrapped. is about to come your bag is almost gone. (which / that is the object in the sentence)

Attributive clauses guided by relative adverbs

An antecedent in which an adverb can be substituted is a noun of time, place, or cause, used as an adverbial in a clause.

1) when, where, why

The relative adverbs "when", "where" and "why" have the same meaning as "preposition + which" structure, so they are often used interchangeably with the "preposition + which" structure, for example:

There, are, occasions, when (on, which), one, must, yield., when everyone has to give in.

Beijing, is, the, place, where (in, which), I, was, born.,, is my birthplace.

Is, this, the, reason, why (for, which), he, refused, our, offer? That's why he refused us to help him?

2) that instead of relative adverb

That can be used for nouns time and location, and the reason to replace when, where, why and the "preposition + which" attributive clause, in informal style that is often omitted (omitted not in formal writing, for example):

His father died the year (that / when / in which) he was born. his father died the year he was born.

He is unlikely to find the place (that / where / in which) he lived forty years ago., he is unlikely to find the place where he lived forty years ago.

Judgment of relative pronoun and relative adverb

Method 1: whether to use a relative pronoun or a relative adverb depends entirely on the predicate verb in the clause. When there is no object behind transitive verbs, we must ask for relative pronouns. Such as:

(error) This, is, the, mountain, village, where, I,, visited, last, year.

(error) I, will, never, forget, the, days, when, I,, spent, in, the, countryside.

(yes) This, is, the, mountain, village (which), I, visited, last, year.

(yes) I'll, never, forget, the, days (which), I, spent, in, the, countryside.

Traditionally, the nouns of tables, places, or time are associated with relational Adverbs "where" and "when". The two question is the misuse of the relation word.

Method two: to accurately determine the antecedent in the attributive clause in the components (the main, predicate and object, and the like), have the right to choose a relative pronoun / adverbs. The antecedent in the clause, subject and object, should choose the relative pronoun; antecedent in the clause adverbial, should choose d..

For example: (to) Is, this, the, museum, which, you, visited,, a, few, days, ago?

(yes) Is, this, the, museum, where, the, exhibition, was, held?
