伊凡有6条绳.每条长25厘米.他用这些绳结在一起形成一条长90厘米的新绳.新绳上每一个结用去的原来绳子的长度都相等.请问每一个结他用去原来绳子的长度是多少?答案是用去2厘米,相当于6条绳分别首尾打结,形成一条长绳.
How many pieces of string does he use in one knot?您这样问,意思是有多少条绳子,不是问长度了.你也不能说How many strings does he use in one knot?这也是问有几条绳子,所以用了How much string……,把绳子长度当成不可数的.或者可以这样:How many lengths of string does he use in one knot?再或者How many centimeters of string does he use in one knot?这样就应该更清楚了吧.
