问题
选择题
— Did you happen to see _______ black and _______ white cat?
— Are they missing? I told you to take care of them.
A．a; 不填
B．the; 不填
C．the; the
D．a; the
答案
答案：C
Are they missing? 中的代词they 是一个很重要的信息词，它表明上文中的 _______ black and _______ white cat 是两只猫而不是一只猫，所以C。the black and white cat 可视为 the black cat and the white cat 之省略。若选A，则表示“一只黑白相间的猫”。
