Present Perfect Practice
This is my first attempt at an exercise. It has three parts: the first practicing irregular verbs, the second contrasting simple past and present perfect and the third practicing for versus since.
PRESENT PERFECT AND PAST SIMPLE
It contains useful exercises to study the past simple and participle forms of some irregular verbs and also some exercises to practice with the present perfect construction of verbs.
Unit 5 - Language focus
3 tasks: 1. Supply the correct tenses of the verbs (in simple past or present perfect); 2. choose the correct relative pronouns to fill in each gap; 3. Put the verbs in the correct tenses and form either in passive or a active voice.
