This week we answer a question from Julio in Peru. He writes: I would like to know the difference between BUY and PURCHASE and when to use each of them. - Julio, Lima, Peru.
本周，我们将回答来自秘鲁的胡里奥提出的一个问题。他写道： 我想知道BUY和PURCHASE的区别以及什么时候使用它们。——来自秘鲁利马市的胡里奥。
Dear Julio, Thanks for asking about these words. As you know, "buy" and "purchase" can be used in similar sentences.
亲爱的胡里奥，感谢您问到了这些单词。如你所知，buy和purchase可用于类似的语句中。
They can both be used either as a noun or a verb. One difference between them is how formal they sound.
它们都可以用作名词或动词。它们之间的区别之一是听起来有多正式。
Compare the following sentences. Put "buy" or "purchase" in the space. I would like to ______ a new home.
比较下列句子。在空格中填入buy或purchase。我想要 ______一套新房子。
She wants to _____ a hamburger. like most English speakers, I would say "purchase" for the home and "buy" for the hamburger.
她想要 _____一个汉堡包。跟大多数讲英语的人士一样，我会说purchase一套新房，buy一个汉堡包。
You probably wonder, why does English have two words with exactly the same meaning? We can understand this better with a little history.
你可能想知道，为什么英语中会有两个含义完全相同的单词？我们可以通过一小段历史来更好地理解这点。
English developed from the languages of Germanic tribes of Northern Europe. Words from that time are what we call Anglo-Saxon.
英语是由北欧日耳曼部落的语言发展而来的。那个时候的言语就是我们所说的盎格鲁 — 撒克逊语。
In the year 1066, William the Conqueror and his forces began to take over England. William was from Normandy, in France.
在1066年，征服者威廉和他的军队开始占领英格兰。威廉来自法国的诺曼底。
For the next 300 years, everyone in English courts and in government spoke French. English was a language for everyday use.
在接下来的300年里，英国法院和政府里的每个人都说法语。英语是一种日常使用的语言。
As a result, French had a great effect on the English language: about 10,000 French words were added to English. We still use many of them today.
因此，法语对英语产生了巨大的影响：英语中增加了大约10，000个法语单词。我们今天仍在使用其中许多的单词。
As you might suspect, English speakers use the French words for more formal situations and the Anglo-Saxon words for common ideas and things.
正如你所猜想的，说英语的人士在较正式的情况下使用法语， 而在表达共同的看法和事物上使用盎格鲁-撒克逊语。
One way you can tell the difference between the French words and the Anglo-Saxon words is their length. Anglo-Saxon words, like "buy," are often short, while "purchase" and other French words are longer.
一种区分法语单词和盎格鲁-撒克逊语单词的方法是它们的长度。盎格鲁-撒克逊语单词通常较短，例如buy，而purchase和其它法语单词通常更长。
Julio asked how to use "buy" and "purchase". We usually use "buy" as a verb.
胡里奥问如何使用"buy"和"purchase"。我们通常将buy用作动词。
For example, I will buy food for the party. It is not so common to see "buy " as a noun, but you do find it in cases like this:
例如， 我将为这次聚会采购食物。"buy"用作名词并不常见，但是在以下情况下确实可以看到：
The police stopped a drug buy on the street. We often use the verb "purchase" for when legal documents are involved, such as in:
警察在街头阻止了一起毒品交易。当涉及法律文件时，我们通常使用purchase，例如：
The government purchased a new contract for 1,000 airplanes. And you should use "purchase" when you need a noun form, as in:
政府签署了新合同，采购了1000架飞机。当你需要使用名词形式时，应使用purchase，例如：
You made a smart purchase when you bought gas before the price went up. In summary, try to use "buy" for simple actions, and "purchase" for more formal exchanges of money for goods.
你在油价上涨前买了汽油，做了一笔好买卖。总之，请尝试在简单行为中使用buy，而在更加正式的买入交易中使用purchase。
