Question

“All my classmates don’t speak Japanese” means “________”.
A.All my classmates won’t speak Japanese
B.None of my classmates speaks Japanese
C.Some of my classmates speak Japanese,some don’t
D.Both my classmates and I never speak Japanese

Answer 1

答案C
根据左栏的讲析,原句中所表达的意思为部分否定,与C项意思一致.B、D两项均表全部否定,A项虽表部分否定,但用won’t不符合原句意思,won’t有“不愿意”的含义.
再如：Not all ants go out for food．
相当于All ants don’t go out for food.并非所有的蚂蚁都外出觅食.
