Exercise 1: Present Simple, Past Simple or Present Perfect
These sentences are written in the present simple, but they are not all correct.
E.g. People nowadays often hate/have hated/hated the effort required to write an essay. The word 'nowadays' tells you that this should be in the present simple, so you should select 'present simple' in the drop down at the end of that sentence.
Then, select which format you think is correct for each sentence. Click 'submit' to see if your answers are correct and read why each sentence sounds better in the present simple, past simple or present perfect.
