A.None of the desks is old B. None of the desks is new
C.All of the desks are old D. Some of the books are new
该选哪个呢? 如果选D表示部分否定的话,那不跟Not all of the desks are new 的意思一样了吗? 如选C的话,那与B又有何区别呢? 急煞我也!
对不起,忘记写题了:“All of the desks are not new”means ( )

只能是选D了,因为只能选一题,A 的意思相反.B 和C相同,不可能选两个.那只能是选D了.
不明白你的老师出这些题目有啥意义.只是为了scramble people's mind.

“All of the desks are not new”means "Some of the books are new ".
