标题: never!用and还是or?

石林语法里说

1)否定句的定义

句子出现no, not(有NONOT才是否定句;“Never… …”是肯定句,表示否定的含义

I have never been to U.S.A and Australia.肯定句

2)否定句用or替换and ,

而GWD某一套语法题里Seldom more than 40 feet wide or 12 feet deep but running
                    
363 miles across the rugged wilderness of upstate New York, the Erie Canal connected

 

我想问一下,到底是出现明确no或not否定词等用or还是只要有否定意味的如never,seldom也适用or?盼NN确认
