Revision of reduced relative clauses
In English, relative clauses can be replaced by to infinitive and participles.
Relatives clauses can be replaced by to infinitive when:
the nouns prior to relative pronouns go with the first, the last, the only.
Example:
+ I was the last student who handed in the test paper.
à I was the last student to hand in the test paper.
the verbs in the clauses indicate something should be done, can be done or must be done.
Example:
+ Do you have any paper which you can sell?
à Do you have any paper to sell?
Relative clauses can be replaced by present participle phrases when the main verb in the clause carries an active meaning.
Example:
+ The girls who are standing at the school gate are in grade 11A.
à The girls standing at the school gate are in grade 11A.
Relative clauses can be replaced by past participial phrases when the main verb in the clause carries a passive meaning.
Example:
+ The cars which are made in Japan are the best.
à The cars made in Japan are the best.
