The Present Perfect Continuous tense is a unique case and poses certain difficulties for English language learners. It is unique in the sense that it has an easy aspect and a difficult aspect.
The difficult aspect is its formation. It needs the auxiliary verb ‘to have’ in its perfect form plus the main verb in its continuous form. This is too complicated for most students, and they usually struggle to get it right.
On the other hand, the easy aspect is its usage. It is used in very specific situations that connect the past with the present, and almost always with specific time expressions like ‘for’ and ‘since’. Hence it is virtually impossible to mix it up with another tense.
This ebook offers clear explanations about both the formation and the usage of the Present Perfect Continuous tense, along with examples. Students who master them can move on to the activities at the end of the book.
