Answer 1

Answer 2

She (read) a book. Present progressive active. Present perfect progressive active.

The present progressive active is used to describe an action that is happening right now in the present. The present perfect progressive active is used to describe an action that started in the past and is still continuing or has just finished in the present.

To form the present progressive active, we use the verb to be in the present tense and the present participle of the main verb (the verb with -ing). For example:

- She is reading a book. (present progressive active) - He is writing an essay. (present progressive active)

To form the present perfect progressive active, we use the verb to have in the present tense, the past participle of the verb to be (been), and the present participle of the main verb. For example:

- She has been reading a book. (present perfect progressive active) - He has been writing an essay. (present perfect progressive active)

The difference between the present progressive active and the present perfect progressive active is that the present progressive active focuses on the action itself, while the present perfect progressive active focuses on the duration or result of the action. For example:

- She is reading a book. (This sentence tells us what she is doing right now.) - She has been reading a book. (This sentence tells us how long she has been doing it or what effect it has on her.)

Some more examples of the present progressive active and the present perfect progressive active are:

- They are playing soccer. (present progressive active) - They have been playing soccer. (present perfect progressive active) - I am studying for the exam. (present progressive active) - I have been studying for the exam. (present perfect progressive active)
