2. It took a lot of time to finish the report .
3. Please give the boy sth to play with .

5. Her wish is to become a pop singer .
T: Tell me the function of the underlined part in each sentence.

S: No.3 is used as the attribute.
S: No.4 is used as the adverbial for purpose.
S: No.5 is used as the predicative.

S: Subject:(8)
Attribute(2)(3)
Object(1)(9)
Adverbial(4)(5)(6)(7)(10)
Step IV Practice
T: Now let’s do some exercises on P6, Ex2 and Ex3.Rewrite the sentences with “to be done” or “to have been done”.
He wanted the nurses to take care of the patient.
—He wanted the patient to be taken care of.
Because “the patient” is the logical object of “take care of”, the passive infinitive should be used in the second sentence.
The car was reported to have been stolen.
But when the action expressed by the Infinitive happens before the predicate, the perfect infinitive should be used.
