问题补充：

—Look at your hands, John. of them is clean.

—OK, I’ll wash them at once.

A. Neither

B. None

C. Both

D. Either

答案：

(答案→)A. Neither

B. None

C. Both

D. Either

解析：根据Look at your hands可知，手是两只，而none是指三者或三者以上的都不，故排除B；根据is可知，前面不能用both；根据I’ll wash them at once.可知，本句的意思应是“没有一只是干净的。”故用neither。所以本题选A。
