t: what he said is right or wrong?
ss: wrong. it is used as the subject, not the attribute.

step iv practice
t: now let"s do some exercises on. page 6. first look at ex. 2. rewrite the following sentences with “to be done”. look at the example on the blackboard.
  (bb: he wanted the nurses to take care of the patient. →he wanted the patient to be taken care of. )
t: because “the patient” is the logical object of “take care of”, the passive infinitive should be used in the second sentence. are you clear?
ss: yes.
t, now i give you three minutes to write your sentences in your books. after that, i"ll  ask some of you to read out your sentences.
   (three minutes later, teacher checks their answers.)

 4. in our lives, there is so much to be learnt
 5. the car was reported to have been stolen
 t: do you have any questions about the answers?
(one student stands up.)
s: why is “to have been stolen” used in stead of “to he stolen” in the last answer?
t: a good question. that’s what i’ll explain to you. when the action expressed, by the infinitive happens before the predicate. the perfect infinitive should he used. here “to be stolen” happen   before “report”. are you clear?
ss: yes.
t: ok. look at ex. 3. rewrite the sentences using the infinitive. the example can help you. first do it by yourself. then discuss it in pairs. finally i’ll show you the answers.
