问题补充：

—What do you think of the songs? —In fact, of them sounds beautiful.

A. not all

B. no one

C. not everyone

D. not every one

答案：

A. not all

B. no one

C. not everyone

(答案→)D. not every one

解析：句意：--你认为这首歌曲怎么样？--实际上，它们的声音并不都优美。分析：因为谓语动词是单数，所以首先排除A. A做主语谓语用复数；no one 指人，不和of 短语连用；not everyone 不能和of 短语连用；只有every one of 才可以和of 连用，这里用的是部分否定，意思是 并非所有的....故选D
