取非意思就是假如某个选项是错的。 大体有三种情况: 1. all----not all/some---none/always----not always/sometimes----never/everywhere---not everywhere/somewhere---nowhere/only one, exactly one---none, more than one/at least one, some---none
有个疑问,是不是取非有时也有两种结果?比如: some---none或all sometimes---never或always everywhere---not everywhere或nowhere somewhere---nowhere或everywhere -- by 会员 icefiremin (2010/1/15 21:57:54)
我觉得不是你说的这样。 取非应该就是只有一种结果。1. all----not all/some---none/always----not always/sometimes----never/everywhere---not everywhere/somewhere---nowhere/only one, exactly one---none, more than one/at least one, some---none 但是,如果句子是 some...not ,那取非后就是none...not,即是all 你说的其他各项就是: some...not--->none...not=all sometimes...not--->never...not=always everywhere...not--->not everywhere...not=nowhere somewhere...not--->nowhere...not=everywhere -- by 会员 finvina (2010/4/18 9:26:17)
他那个例子应该是两种,也可以说是一种或多种, some取非是 not some, 而not some包括 none和all. |
