Answer 2

Answer:

Fill in the blanks with correct form of verbs:

1. These days, more and more are (1) keeping (keep) pets but they have still (2) to know (know) about their physiology. Before (3) bringing (bring) a pet into

the house it is better (4) to acquaint (acquainted) yourself with its habits.

(1) 'Keeping' is playing the role of main verb in Present continuous Tense because 'are' has been placed before it.

(2) 'To know' is a 'To - infinitive.'

(3) 'Bringing' is a gerund or present participle.

(4) 'To acquaint' is again a 'to-infinitive'.
