Question

“All my classmates don’t speak Japanese” means “________”.

1. A.
   All my classmates won’t speak Japanese
2. B.
   None of my classmates speaks Japanese
3. C.
   Some of my classmates speak Japanese, some don’t
4. D.
   Both my classmates and I never speak Japanese

Answer 1

C
根據(jù)左欄的講析，原句中所表達的意思為部分否定，與C項意思一致。B、D兩項均表全部否定，A項雖表部分否定，但用won’t不符合原句意思，won’t有“不愿意”的含義。
再如：Not all ants go out for food．
相當(dāng)于All ants don’t go out for food.并非所有的螞蟻都外出覓食。
