Here is a Cultural Literacy worksheet on Angola. This is a full-page worksheet with a reading of four compound sentences and nine comprehension questions. This is a good general introduction to the country including its geography and its history, including the relatively recent history of the Angolan Civil War. Early on, during the 1970s the Angolan conflict was a proxy war pitting, essentially, the United States against the Soviet Union, i.e. a “war which came in from the cold,” as the late Hampshire College professor Eqbal Ahmad put it.
So, this would make a good independent practice (i.e. homework) assignment. Or, because it is formatted in Microsoft Word (as is the majority of material you’ll find on this site), you can revise it to suit the needs of your students.
If you find typos in this document, I would appreciate a notification. And, as always, if you find this material useful in your practice, I would be grateful to hear what you think of it. I seek your peer review.
