either…or…表示两种可能性中任选一种,其后面必须连接两个相同的句子成份。例如:
The sentence can be either true or false.句子要么是对的要么是错的。
You can either come with me or walk home.
你要么跟我一块去,要么走回家去。
Either mum or I cook supper.要么我母亲要么我做晚饭。
neither…nor…连接两个相同的句子成分,表示否定的意思。动词的单复数形式与nor后的单词主谓语相一致。例如:
Neither Li Lei nor Wang Hai was there.李雷和王海都不在那里。
I neither watch TV nor listen to the radio.我既不看电视也不听收音机
问:Either - Or 和 Neither - Nor 有什么区别?怎样决定应该用哪一个呢?
答:两者的不同主要取决于句子在文中是表示肯定还是否定的意思。例如:
I would choose either the chocolate or the strawberry flavoring.
I would choose neither the chocolate nor the strawberry, because I prefer vanilla.
你可以发现,如果是选择两者中的某一个,那么就应该用either - or。如果问中的意思是否定的,那么就选用neither - nor。
