III. Grammar: 
Relative clauses replaced by participles and to infinitive
1. Active participles: 
She is Lan’s sister. 
What’s she doing?
g She’s playing with her dog
a. The girl who is playing with the dog is Lan’s sister. 
g The girl playing with the dog is Lan’s sister.
b. The man spoke to John is my brother. 
g The man speaking to John is my brother.
Note: We can use a present participle to replace a relative clause which has an active meaning. 
2. Passive participles
The picture which was drawn by a blind has won the first prize. 
g The picture drawn by a blind has won the first prize. 
Note: We can use a past participle to replace a relative clause which has a passive meaning. 
3. Infinitive relative clauses
a. Which was the first country which won the world cup? 
Have Ss to ask that question in another way. 
g Which was the first country to win the world cup?
b. The last person who leaves will have to turn out the lights. 
g The last person to leave will have to turn out the lights.
Notes: 
We can use a to-infinitive to replace a relative clause. 
We often use a to-infinitive after an ordinary number (first, second) after next, last, after, only and after superlative adjectives.
