关于小知识的：
在生活中我们经常看到英文字母，但是意思却各不相同 。现在给大家举几个例子：
处方笺上的“R”：在医院的处方上印有一个大写字母“R”，意思是“取下列药品” 。图书统一书号上的“R”：有的图书统一书号后面印有一个“R”和两组数字，这里的“R”表示该书是少年儿童读物 。商标上的“R”：我们经常看到在商品包装的一角上印有一个“R”标记，它表示这些商品的商标是经过注册的 。注册商标符号是世界通用的 。电影上的“R”：是Restricted的第一字母 。在美国指限级电影，未满17岁者必须有成年的监护者带领才能入场 。荧光屏上的“R”：当我们收看电视节目时，有时电视屏幕会出现一个标记，并且还会一闪一闪的，它是英文Repeat的第一个字母，表示“慢镜头重放” 。
另外，几何和工程图中的“R”表示半径；热学中的“R”表示普通气体常数；电学中“R”表示电阻；试卷中的“R”表示正确 。

在银行柜台，银行职员认真仔细的检查了每一张钞票看，是否有假 。这种做法使老妇人很不耐烦，最后实在忍不住说：“相信我，先生，也请你相信这些钞票 。
这都是真正的美元，是从美国直接带来的 。” He Won Tommy: How is your little brother, Johnny? Johnny: He is ill in bed. He hurt himself. Tommy: That's too bad. How did that happen? Johnny: We played who could lean furthest out of the window, and he won. 他赢了 汤姆：约翰尼，你小弟弟好吗？ 约翰尼：他害病卧床了 。
他受了伤 。汤姆：真糟糕，怎么回事儿？ 约翰尼：我们做游戏，看谁能把身子探出窗外最远，他赢了 。
I Have His Ear in My Pocket Ivan came home with a bloody nose and his mother asked, "What happened?" "A kid bit me," replied Ivan. "Would you recognize him if you saw him again?" asked his mother. "I'd know him any where," said Ivan. "I have his ear in my pocket." 他的耳朵在我衣兜里 伊凡鼻子流着血回到家里 。他妈妈问，“发生了什么事？” “一个男孩咬了我一口，”伊凡说 。
“再见到他你能认出来吗？”妈妈问 。“他走到哪里我都能认出他，”伊凡说 。
“他的耳朵还在我衣兜里呢 。” A Good Boy Little Robert asked his mother for two cents. "What did you do with the money I gave you yesterday?" "I gave it to a poor old woman," he answered. "You're a good boy," said the mother proudly. "Here are two cents more. But why are you so interested in the old woman?" "She is the one who sells the candy." 好孩子 小罗伯特向妈妈要两分钱 。
“昨天给你的钱干什么了？” “我给了一个可怜的老太婆，”他回答说 。“你真是个好孩子，”妈妈骄傲地说 。

Drunk One day, a father and his little son were going home. At this age, the boy was interested in all kinds of things and was always asking questions. Now, he asked, "What's the meaning of the word 'Drunk', dad?" "Well, my son," his father replied, "look, there are standing two policemen. If I regard the two policemen as four then I am drunk." "But, dad," the boy said, " there's only ONE policeman！" 醉酒 一天，父亲与小儿子一道回家 。这个孩子正处于那种对什么事都很感兴趣的年龄，老是有提不完的问题 。
他向父亲发问道：“爸爸，‘醉’字是什么意思？” “唔，孩子，”父亲回答说，“你瞧那儿站着两个警察 。如果我把他们看成了四个，那么我就算醉了 。”
“可是，爸爸，”孩子说，“那儿只有一个警察呀！” Hospitality The hostess apologized to her unexpected guest for serving an apple-pie without any cheese. The little boy of the family left the room quietly for a moment and returned with a piece of cheese which he laid on the guest's plate. The visitor smiled, put the cheese into his mouth and then said: "You must have better eyes than your mother, sonny. Where did you find the cheese?" "In the rat-trap, sir," replied the boy. 好客 由于客人在吃苹果馅饼时，家里没有奶酪了，于是女主人向大家表示歉意 。这家的小男孩悄悄地离开了屋子 。
过了一会儿，他拿着一片奶酪回到房间，把奶酪放在客人的盘子里 。客人微笑着把奶酪放进嘴里说：“孩子，你的眼睛就是比你妈妈的好 。
