price定价(指卖方对物品所要求的价格,高于cost)
cost价值,成本(指对货物所付的一切代价,如制作、包装、运输等)
value价值(按人的主观判断对物品本身内在的有用评价)。如:I paid him $500 for the painting, but its real value must be about $50,000.
worth价值(指物体本身永远不变的价值,含着一定金额的数量,用法比较特殊)。如:sth be worth +ing(不用动名词的被动式和不定式)。“sth be well worth+钱”是“某物相当值钱”。
charge索价(指为其提供服务后所要求应付的价钱,常用句型:charge sb+钱+for sth。free of charge免费)
expense开支,花费(指对……的实际开支花费的金额,常用于:at the expense of , at one\s expense以……为开支)
(5)询问价格有多种表达方式。如:这个你要卖多少钱?How much do you ask for (want for, sell) it ?=How much does this cost?=How much is this worth?=What
