石林语法里说
(1)否定句的定义
句子出现no, not时(有NO,NOT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
