Revision of reduced relative clauses
In English, relative clauses can be replaced by
to infinitive and participles.
1. 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.
 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?
 Do you have any paper to sell?
2. 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.
 The girls standing at the school gate are in
grade 11A.
3. 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.
 The cars made in Japan are the best.
