选择题
Dr. Peter Spence, ____ headmaster of the school, told us, “____ fifth of pupils here go to study at Oxford and Cambridge.”
A．a; A
B．不填；The
C．the; The
D．不填; A
答案
答案：D
题目分析：句意为：____ headmaster of the school作了Dr. Peter Spence的同位位，官职，头衔作同位语时前面要使用零冠词，故第一个空应不填；第二个空a fifth表示的意思是one fifth即五分之一的意思，故第二个空应为a.所以答案为D。
