▲从语法上看,Nobody believes A and B 和 Nobody believes A or B 都对,它们的不同之处在表达的侧重点:
Nobody believes A and B. 没有人相信A和B。(把A和B当作一个整体来看)
Nobody believes A or B. 没有人相信A或B。(把A和B当作两个个体来看;本句可以理解为人们既不相信A也不相信B)
▲例句:
No one doubted his ability, his industry and his integrity. 没人怀疑他的能力、勤奋和正直。(把能力、勤奋和正直作为一个整体来看待)
No one doubted his ability, his industry or his integrity. 没人怀疑他的能力、勤奋或正直。(把能力、勤奋和正直作为三个个整体来看待,既不怀疑他的能力,也不怀疑他的勤奋,也不怀疑他的正直)
