The professor gave us talk on multicultural Canadian society, topic few of us are familiar with.
A. a; the
B. the; a
C. a; a
D. the; the

(答案→)A. a; the B. the; a C. a; a D. the; the解析：考察冠词。本题第一空后的名词talk表示发言，是一个可数名词，用a表示泛指。第二空名词topic后面有定语从句修饰，表示特指，故使用定冠词the。句意：这位教授给我们做了一个关于多元文化的加拿大社会的报告，这是一个我们中很少有人熟悉的话题。故A正确。
