core interests既然是核心利益，谓语为什么又用复数又用单数？

CoreinterestsusuallynoteareasofgreatimportanceforBeijingconsideredvitaltonationalsurvival,andnotupfornegotiation.

What are Chinas core interests?

虽然做“利益”讲的时候用复数名词形式，可逻辑上应该和profits一样谓语用单数才对，为什么例句里谓语又有复数又有单数？

Coreinterestsusuallynoteareasof greatimportanceforBeijingconsideredvitalto

nationalsurvival,andnotupfornegotiation.

【答】Coreinterests是复数作主语，谓语动词用复数note，这是正常的。

What are Chinas core interests?

【答】此句中的 Chinas core interests 是主语，What 是表语，谓语动词用are 也是正常的。
