后面是一个从句 if it is a fine day tomorrow 意思是明天是不是一个好天. he wants to know if it is a fine day tomorrow. 而不是he wants to know ( if it is a fine day )tomorrow. 楼上的说得对
你被 tomorrow给误导了 这句话的意思是他想知道明天的天气是不是一个好天而不是 他明天想知道天气是不是一个好天。 he wants to know if it is a fine day tomorrow. 而不是he wants to know ( if it is a fine day )tomorrow
