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
生活缺少的是发现美的眼睛作文【二】
笑归笑，我脑里不由得浮起一个问号：书上说蜗牛是有眼睛的，它不只是靠触角识别方向。但蜗牛的眼睛在哪？我怎么看不见它呢？
于是我捉了几只蜗牛，放进玻璃缸里，扔下几片白菜叶，想看看清楚蜗牛的眼睛到底在哪儿。
第一个探索目标是蜗牛的上身，我想蜗牛的眼睛应该和其他动物一样在嘴巴周围吧，我躲在柜子边偷偷观察玻璃缸中&ldqu;熟睡&rdqu;的蜗牛。不久，一只大一些的蜗牛从&ldqu;门口&rdqu;探出了头，头上的两只触角也伸了出来。只见它慢吞吞地爬到菜叶上，又慢吞吞地找嫩叶，才慢吞吞吃起来。见它吃得正津津有味，我才悄悄地直起身，用放大镜对着它看，朝嘴巴那儿看。也许是它的嘴巴太小了，几乎看不出在咀嚼。但放大镜中的.蜗牛嘴巴周围，除了细小的条纹外，没什么像眼睛的。
第一个探索目标失败！
我的第二个探索目标是蜗牛的触角，因为它吃叶子的时候。都要先用触角碰一碰。
又有一只蜗牛&ldqu;醒&rdqu;了，我正好验证一下是不是每只蜗牛吃食时都用触角碰一碰。
果然不出我所料，那只蜗牛爬到菜叶上后，便伸长了触角碰了碰。我便用放大镜对着它的触角看。只见触角的顶端有两颗圆圆的眼睛‐‐跟其他动物一样，眼白中间有一点黑圆点。
我又反复对其他蜗牛作了观察，结果都一样。
第二个目标探索成功！
真高兴，我发现了蜗牛的眼睛，在触角的顶端。
