为什么每次考试总在either...or上栽跟头?因为90%的人都不知道:动词永远只认最近的那个主语!
什么是「就近原则」?
当either...or、neither...nor、not only...but also等连词连接两个主语时,动词必须像磁铁一样紧紧吸附最近的名词。例如:
Either the teacher or the students are responsible.
(动词are跟着复数名词students)
三大必考场景拆解
▍场景1:单数 vs 复数
当两个主语单复数不同时,动词永远向右边看齐:
Neither the book nor the pens were on the desk.
(距离动词更近的pens是复数)
▍场景2:人称混搭
当出现不同人称的主语时,动词形态跟着最后一棒选手:
Either you or I am going to present.
(动词am匹配最近的主语I)
▍场景3:倒装陷阱
在倒装句型中,动词依然死守就近原则:
Not only does she sing, but also dances.
(dances与she保持单数一致)
高频翻车现场
❌ Either the dogs or the cat are hungry.
✅ Either the dogs or the cat is hungry.❌ Not only Mary but also her brothers has arrived.
✅ Not only Mary but also her brothers have arrived.
终极记忆口诀
"Either左or右排排坐,
动词只跟右边走。
单复数来分不清?盯紧最后准没错!"
