英语选择题The coat is only fifteen dollors .I'll _it

The coat is only fifteen dollars .I'll _it A.sell B.take C.sale D.buy
答：BD
译：这件上衣只要15美元.我就买这件.
析：本题考词汇和习惯表达.买东西时,说“这个我买了”,“我就买这个”说：I'll take it. =I'll buy it. 并不表示自己不用花钱就“拿走”这件大衣.sale是名词,排除C. sell 是卖,是商家的行为.而这句话应该是顾客说的.排除A.出题者可能是根据书上现成的对话编的题目.而原题句很有可能是take, 认为这里只能用take,不能用buy,而汉语翻译及思维常常是“买”,所以用了buy这个“干扰”项.确实让大家很困惑：这里buy对不对?行不行呢?
评：本题语境不是很明确,难以判断第一句话是顾客还是卖家说的话.如果是对话,最好是用--,--并分成两行.这题给人的感觉是一顾客说了两句话.但作为顾客,不会当着卖主的面说：“这上衣只要15美元” 的话的.这很象是卖主的推销用语.买主通常情况下是说东西贵了,要求便宜一点的.
不过很有可能是在购物时对朋友说的话.
现在常考小语境单选题,我们在做题时,经常要考虑这个语境.是什么人在什么情况下对什么人说的这个话.
这个问题不弄清楚,这题就有争议.
请看网上支持B项的语言实例：
The woolen coat is cheap enough.I'll take it 这毛衣很便宜.我买了.
网络上有关于用take还是buy的讨论,摘取其中一个：（大海）
I'll take it/them. 我要了,我买了.
当你认为某种东西称心,价格合理,决定要买时,可用I'll take it(them).或I'll have it(them).有时还可以在这两个句型后加上一个副词then(那麽）.意思与I'll buy it/them一样,你要说I'll buy it/them别人也是会懂的,但英语人一般不习惯说 I'll buy it.另外还要注意的是毕竟take意思很多,所以I'll take it还有别的意思,可用于别的场合.
实例：
--How much is the bike?
--Two hundred yuan.
--Oh,it's cheap. I'll take it.
--这辆自行车多少钱?
--200元.
--噢,很便宜.我买了.
--How much do these books come to?
--Five hundred yuan.
--Oh,that sounds reasonable.I'll have them then.
--这些书总共多少钱?
支持I'll buy it的对话：
"I'll buy it. How much do you want?" John said. "One hundred thousand dollars," the man said. This was a lot of money, but John paid him. Then he sent the bird to his mother with a birthday card.
有一篇很有意思的文章,叫“杀猪匠A给漏屋与大学英语老师khxia上一课：I’ll buy it.永远不等于I’ll take it.”,大家自己搜索一下找来看看.度娘不让链接.
