Question

Ex. 1 Put the verbs in brackets into the Present Perfect Simple or Present Perfect Continuous (раскрой скобки употребив глагол в Present Perfect Simple или Present Perfect Continuous)

Don't walk here. I…........(just/clean) the floor.
Jane is hungry. She …............(not /eat) anything for six hours.
She is tired. She …......(study) for four hours.

Sandy …...................(teach) English for 10 years.
Chris …..................(not/do) the washing up yet.
He …......................(walk) all the morning.
They.......................................(play) in the garden for two hours.

Answer 1

1. have just cleaned

2. hasn't ate

3. has been studying

4. have seen

5. has been teaching

6. hasn't done

7. has been walking

8. have been playing

Во втором можно сказать, что обозначается процесс, но если там использовать Present Perfect Continuos, но так, мне кажется, это будет просто отрицание.
