下面再看始动性动词become和延续性动词remain之间的语义逻辑关系：

19） a． John became a smoker．

b．John didn't remain a non－smoker．

（约翰开始吸烟。／约翰不再不吸烟了。）

20） a．John became a non-smoker．

b．John didn't remain a smoker．

（约翰开始戒烟。／约翰不再吸烟了。）

21） a．John didn't become a smoker．

b． John remained a non－smoker．

（约翰并没有开始吸烟。／约翰继续不吸烟。）

22） a． John didn't become a non－smoker．

b． John remained a smoker．

（约翰并没有开始戒烟。／约翰继续吸烟。）

上面四组例句中become和remain的语义逻辑关系如下：

become a smoker = not remain a non-smoker
become a non-smoker = not remain a smoker
not become a smoker = remain a non-smoker
not become a non-smoker = remain a smoker

下面再以 be awake／be not asleep和be asleep／be not awake为例，说明始动性动词和延续性动词之间的

语义逻辑关系：

23） a． John is already awake．

b． John is no longer asleep．

（约翰已经醒了。／约翰不再睡了。）

24） a． John is already asleep．

b John is no longer awake．

（约翰已经睡了。／约翰不再是醒着。）

25） a． John is not yet awake．

b．John is still asleep．

（约翰还未睡醒。／约翰还在睡。）

26） a． John is not yet asleep．

b．John is still awake．

（约翰还未睡着。／约翰仍是醒着。）

上述 be awake和be asleep之间的语义逻辑关系，可以总结如下：

be already awake = be no longer asleep
be already asleep = be no longer awake
be not yet awake = be still asleep
be not yet asleep = be still awake
