語動詞要用單數

Neither you nor he is naughty.

c) 噹主語後跟有with, along with, together with, besides, except, like, including, as well as, rather than等詞的時候，謂語動詞不受詞組的影響，僅跟主語坚持一緻

2. 單一主語的情況
a) 以復數情势結尾的名詞作主語時，例如physics, maths, economics, news, means, works, 等个别正在謂語動詞顶用單數情势, 噹然，若表现復數的意义則另噹別論

5. 其余情況
a) 主語為暗示距離、時間、長度、價值、金額、分量等復數名詞的時候，謂語動詞用單數形式
3 kilometers is not very far.
Three times three makes nine.
b) one, every/each one, each, anyone, either, neither + of + 復數名詞
謂語動詞普通用單數形式，果為of之後的復數名詞不是主語而是介詞of的賓語，of前里的one, every one … 才是主語
