选择题
I was told that there were about 50 foreign students __________Chinese in the school, most __________were from America.
A．study；of whom
B．study；of them
C．studying；of them
D．studying；of whom
答案
答案：D
考察分词用法和定语从句。现在分词短语Studying Chinese in the school修饰名词students,因为两者之间存在主动关系，所以使用现在分词的形式。第二空是定语从句，whom指代50 foreign students，作为of的宾语。
