I wonder if you can walk.和 I wonder if you can't walk.有什么区别啊?
"The shark dove to the depth of up to 3,215 feet (980 m).But it spent most of its time swimming along the surface,making some scientists wonder if sharks,like ancient mariners,don't use celestial cues to find their way straight across the sea."这是原句子,大家的回答似乎都没有清楚的说明if后面从句的具体用法。不过我同意Ocean17faraway的判断,if这里后面的肯定与否定,意思都一样。但是希望有高手来具体说说他们的差别,抑或肯定他们之间没有差别。
意思相同,后面那句不符合英语习惯.
我想知道你能否走路.
