冰淇淋是生活中不可缺少的一道美食。夏天没胃口时，尝些冰淇淋，是一个迅速补充体力降低体温的好方法。尤其对小朋友来说更是挡不住的诱惑，聪明的妈妈能在小朋友不愿吃饭时，偶尔改变方式以冰淇淋取代主食，同样能摄取营养和热量，漂亮的颜色又让人产生食欲。
你知道吗？美国每年能销售10亿加仑的冰淇淋，8%的牛奶最终变成冷冻食品。如今，各种各样的冰淇淋店更是遍布世界。现在就让我们一起看看冰淇淋的历史吧。
The earliest reports of people enjoying flavored ice desserts come from the Romans and the Chinese. Marco Polo returned from his famous expedition with fruit-flavored ices, reporting that Asians had been making them for thousands of years. These delicacies became popular in France in the 1500s, but only among royalty. Over the next few centuries, the process of making them evolved from hauling mountain ice to salt/ice freezing methods. Cream was introduced as an ingredient, and by the 1700s, people were enjoying a dessert that was very similar to today's ice cream.
The hand-cranked ice cream freezer was first developed by Nancy Johnson in 1846. Ice was readily available from large warehouses in that era, so ice cream became a treat that could be enjoyed by almost anyone, not just the rich. Ice cream making was revolutionized again in 1851, when Jacob Fussel started the first wholesale ice cream manufacturing operation in Baltimore, Maryland. Fussel's dairy business had excess cream and he couldn't figure out what to do with it. He tried using it to make ice cream, and before long his ice cream business outsold the rest of the dairy.
The business slowly evolved for the next few decades. Manufacturing methods and ingredients improved, while refrigeration technology became cheaper and more efficient. By the 1920s, home refrigerators and freezers became more common, which gave the ice cream industry another boost. Sugar was rationed in the US during World War I, but the ice cream industry convinced the government that ice cream was an "essential food”. Ice cream factories were allotted sugar rations and production continued.
Ice cream increased in popularity until the Depression years caused a drop in sales for virtually all non-essential goods. Sales increased in the years leading up to World War II before leveling off in the post-war years. The rise of the giant supermarket created demand for cheaper, mass-produced ice cream, but quality suffered. The 1960s saw a resurgence in "premium"ice cream, while the following decades saw the market fragment into low-fat varieties for the health-conscious, including frozen yogurt, fruit bars, ice milk, fat-free ice cream, and dozens of other varieties. However, ice cream still makes up about 60 percent of the market share among frozen desserts. While ice cream is enjoyed worldwide, it has become an American tradition

我家门前的桂花树上有几只蜘蛛，我早就想抓一只研究一下了。可是树太高了，我试了很多办法都捉不到一只。 一天，我又来捉蜘蛛了，这次我学了爬墙的新功夫，希望墙边有蜘蛛。我来到墙边，向头顶上看，遗憾的是更本没有什么蜘蛛。当我摇摇头准备离开时，我发现了一个神秘的礼物：一只蜘蛛正从它的网上垂下来。我立即把瓶子放在蜘蛛的正下方，来一招“守空待蛛”蜘蛛就抓住了，真是“得来全不费工夫”啊。
小蜘蛛在瓶子里乱窜，我更本看不清楚，心想：干脆做作业去算了，你累死吧。这时，小蜘蛛不动了，想必它也累了，绝望了。我不失时机，把它扣在一个玻璃鱼缸里，好仔细观察嘛。这时，我才发现是由圆圆的身子，小小的脑袋和肥肥的腿组成了这只蜘蛛。
我怕它饿得慌，所以天天抓一只活蚊子给它吃。可是，我给它捉了好多蚊子，它都不吃一只。经观察：原来，是玻璃缸的问题。玻璃缸对它来说是个陌生的环境，它不肯织网。我心想：看来不让它织网它就要饿死了，我必须把它放了，它才不会死。于是，我毅然决定把它放了。看着它就要消失的时候的背影，我的心中洋溢着一种前所未有的快乐感觉。
每每当我想起那只蜘蛛，想到它坐在一张网上吃着它自己捕捉的猎物时，这种感觉又涌上了心头。 有时，让别人快乐也能让自己快乐，这是我认为的生活中的乐趣。
