奥运第5天:比赛进入白热化 - August 02, 2012

LONDON — South Africa is the lone African gold winner so far at this year's Olympics, with three medals. But that is not surprising. More than half of sub-Saharan African countries have never won gold, and many have never won a single Olympic medal.

A total of 39 African nations have never won gold at the Games. Of those, 28 have never won any medal. That list includes the small, the poor, the coup-prone and the otherwise blighted.

Egypt won its first-ever fencing medal, a silver, on Tuesday.
