Rushtosummer的学习笔记(23)Relative Pronouns
Introduction and General Usage in Defining Clauses
Relative pronouns are that, who, whom, whose, which, where, when, and why.
In English, the choice of the relative pronoun depends on the type of clause it is used in. There are two types of clauses distinguished: defining (restrictive) relative clauses and non-defining (non-restrictive) relative clauses. In both types of clauses the relative pronoun can function as a subject, an object, or a possessive.
Relative pronouns in defining clauses
Defining relative clauses (also known as restrictive relative clauses) provide some essential information that explains the main clause. They are opened by a relative pronoun and ARE NOT separated by a comma from the main clause.
The table below sums up the use of relative pronouns in defining clauses:
Function in
the sentence
| Reference to
| People
| Things / concepts
| Place
| Time
| Reason
| Subject
| who, that
| which, that
| | | | Object
| (that, who, whom)*
| (which, that)*
| where
| when
| why
| Possessive
| Whose
| whose, of which
| | | | In American English, whom is not used very often. Whom is more formal than who and is very often omitted in speech.
General remarks: That, Who, Which compared
The relative pronoun that
can only be used in defining clauses. It can also be substituted for who (referring to persons) or which (referring to things). That is often used in speech; who and which are more common in written English.
Some special uses of relative pronouns in defining clauses
that / who
Referring to people, both that and who can be used. That may be used to refer to someone in general. However, when a particular person is being spoken about, who is preferred.
that / which
There are several cases when that is more appropriate than and is preferred to which:
After the pronouns all, any(thing), every(thing), few, little, many, much, no(thing), none, some(thing);
After verbs that answer the question WHAT? For example, say, suggest, state, declare, hope, think, write, etc. In this case, the whole relative clause functions as the object of the main clause.
After the noun modified by an adjective in the superlative degree;
After ordinal numbers, e.g., first, second, etc.;
If the verb in the main clause is a form of BE;
Relative Pronouns in Non-Defining Clauses
Non-defining relative clauses (also known as non-restrictive, or parenthetical, clauses) provide some additional information which is not essential and may be omitted without affecting the contents of the sentence. All relative pronouns EXCEPT "that" can be used in non-defining clauses; however, the pronouns MAY NOT be omitted. Non-defining clauses ARE separated by commas.
The table below sums up the use of relative pronouns in non-defining clauses:
Function in
the sentence
| Reference to
| People
| Things / concepts
| Place
| Time
| Reason
| Subject
| who
| which
| | | | Object
| who, whom
| which
| where
| when
| why
| Possessive
| whose
| whose, of which
| | | | Some Special Uses of Relative Pronouns in Non-Defining Clauses
a.which
If you are referring to the previous clause as a whole, use which
b.of whom, of which
Use of whom for persons and of which for things or concepts after numbers and words such as most, many, some, both, none
Defining vs. Non-Defining and ESL Tips
Defining vs Non-Defining Clauses: Difference in Meaning
the following summary may be helpful if you need to make a quick decision:
1.Use that if the main clause poses the question WHAT? answered by the relative clause;
2.Do not use that presenting non-essential, additional information (that is, in non-defining relative clauses); use who or which instead;
3.Use who to refer to people;
4.Use which to refer to things or to refer to the previous clause as a whole;
5.If you choose between who or that, use who in writing;
6.If you choose between which and that, use which in writing;
7.Do not put a comma before that.

Pattern Four: Compound Sentence
Independent clause [ ; ] independent marker [ , ] independent clause [ . ]

Pattern Five: Complex Sentence
Dependent marker dependent clause[ , ] Independent clause[ . ]
