借款。
To Mr. Charles Green, May. 18, 20xx

兹借查尔斯•格林先生叁仟美元(U.S. $3000)，年息四厘，自即日算起，一年内归还。
借款人 戴维•史密斯 20xx年5月18日
I. O. U.= I owe you 也可写成IOU, 即“我欠你”的意思，译成汉语为“今欠”、“今借到”。
借条(I.O.U.)：
借条是熟人间的便笺形式。留下字据，表示欠某人某物。与收据一样，借条需写明借钱物名称和数量、立据人及日期。具体写法是：将时间写在正文的右上角，在正文的右下角署名，正文中须指明向借用人借用何物，文字要求简洁，其中所涉及的数字，须用英文拼出，相当于汉语的“人民币大写”，若是定期偿还的借据，还须注目偿还时间。常用的短语如: “Borrowed from „”, “I.O.U.(I owe you)” 意思是” 兹借到„„”。

Dear Xiao Wang:
I wonder if I could borrow your electronic dictionary for a few days. Now I am translating some important articles. There are many new words which I have to look up the dictionary usually. I just have a paper dictionary but of course it’s not as convenient as the electronic one, which has a bad effect upon my velocity of my translating. So I think your electonic dictionary is more suitable for me to complete my work. I promise that I must be very careful of your dictionary and make no damage done on it. Thank you very much!
Yours ever
