Question

--- Really? Who will give ______ lecture? What is it about?
--- Professor Chen, ______ President of Peking  University, about pollution.

A．the; a

B．a; the

C．the; 不填

D．a; 不填

Answer 1

C

由Really?(真的吗？)可判断上一句可能是：I hear that there will be a lecture. 因此第一空应填the。President of Peking University在句中用作同位语，故前面不用冠词。
