新概念3册1课
课文中出现一句experts confirmed that a puma will not attack a human being
从句是不是应该用would啊书印错了么?

是正确的.
would 是 will 的过去式,一般用在过去时态中和表示委婉语气的情景下.如：I would like a cup of tea.我想要一杯茶.
此处之所以用will,是因为它阐述的是一个自然现象,应用一般现在时态或者将来时态.美洲狮不会袭击人类,就是一个自然的存在现象.所以用will.
你考虑的是宾语从句的时态一致问题,有时候不一定要完全一致的,特别是在阐述自然现象的时候.如：He said the sun rises every day. 太阳每天升起就是一个自然现象,不需要变成过去式.

英语的虚拟语态新概念第三册第一课就有一个句型:a puma will not attack a human being experts were convinced that the animal was a puma.experts we 关于UnlessUnless表示if not.在新概念三第一课里有一句...,and experts confirmed 新概念3中第一课 A puma at large中,HAVE的用法疑惑新概念3第一课puma at a large 新概念英语3第一课“A puma at large” Were the experts sure that the animal was a puma?Why? 新概念三的英语问题!新概念三第一课中：A wild puma had been spotted forty-five m 《新概念英语》（第三册）第一课《A Puma at Large》有谁知道A puma at large在英语新概念三册的第几课? 71：some experts are not surprised that 从句.这个that 从句在句中充当什么成份新概念英语第三册第一篇课文里单词PUMA的发音究竟是?
