不可缺少的勇气800字作文【一】
别人眼中的勇气，是即使你害怕的事，你勇敢去做，不害怕。勇气，是到了新的'班级，主动大大方方向别人自我介绍；勇气，是跟好朋友吵架后，主动自己先握手言和；勇气，是勇敢面对比赛。
自信心和勇气是两位好朋友，”它们”总是一起工作，为什么？一个拥有了勇气，自信也就像跟屁虫一样跑出来。
“啊──”从一零一上面跳下，这是勇气吗？绝不是，这是”傻气”；台风天跑去爬山是勇气吗？不是。我与好朋友分离时，是双面人的我，在与朋友分开时，我吞下那想哭的，一回家，我觉得受够了，我泪雨如下，疯狂地哭着，有时我会闷闷不乐，我没有勇气当着朋友的面哭。我最有勇气时，是我写字比赛的时候，我会全力以赴，尽我所能做到最好；我最胆小时，是我自己的失误、失败、粗心。
勇气像空气，在日常生活中，不可或缺，在生活中我们常听见：”我没勇气！”这样会让我们更没勇气喔！找找自己真正的勇气吧！

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
不可缺少的勇气800字作文【三】
有个穷人生活在一个城市里，他只有一个哥哥一个弟弟，但哥哥因而把家产赌光了被警察抓去坐牢了，弟弟出车祸而，现在，这个家只剩下他了。这几年，他靠捡破烂卖钱为生。这个穷人心地善良，卖了钱，自己只花一小部分，剩下的他全部的捐给了孤儿院，为那些可怜的孤儿创造了一些美好的环境。
一天，这个穷人，又骑着那辆小三轮车去捡破烂了。他走遍了街巷，翻遍了每一个垃圾桶，找遍了每一个角落。到了中午时才捡了三袋子的塑料瓶。这穷人虽然很累，但脸上挂满笑容。可是他非常不幸，就在这时，从远方走来了一个城管，这城管不仅不关心这个苦命的穷人，并且还非要拉走穷人的`小三轮车，以免他在骑着三轮来这儿捡破烂。穷人没有办法，只好把车留在这儿，拿走那三袋辛辛苦苦捡来的瓶子，自个背着去卖，但是从这儿到垃圾回收站太远了！穷人不得不打个车过去。他走到车站等了一会儿，一辆公交车停拉下来。穷人走了上去，但又被赶了下来。因为司机先他脏，怕他扰乱了生意。穷人只能自己往回收站走了。
当快到回收站时，路过一家公司，一个大老板从公司急匆匆地走出撞到拉穷人。穷人辛辛苦苦捡来的瓶子撒了一地，而那大老板反而站那儿就破口大骂，穷人病性大发晕了，那大老板却跑了。时间一分一秒过去了，却没有一个人把他送入医院。最终，跑来了一个小男孩，小男孩仅仅才七岁，他哭着让他爸爸把穷人送入了医院。
在医院里，没人照顾穷人，没有人为穷人救诊，只有两个好心的女护士把他扶到了一个角落的床上。后来，来了一位富翁，来这看病。这富翁却让最好的医生和院长来给他治，医生却口口声声的答应了。
傍晚时分，医生们下班了，一个医生看到了穷人。当医生去喊他时，发现他已没有呼吸。这件事传到了警方的耳朵里。几个警察查了一下这市区的摄像头，并找到了城管、公交车司机、穿着华丽的大老板和那些医生。
警察问他们的时候，他们却都有自己的理由，并且推托责任。警察没再追问处理。
以上，这几种人是世上最可耻的人，最自私的人，他们连一个七岁的小孩都不如。
如果，有一个人关心了穷人，穷人就不会得到如此下场。所以，我们的世界还是缺少关心。
世上没有穷苦富贵之分，只有心肠好坏之分。只要是人，就要有一颗火热的心，就要有懂得关爱他人，同情他人的美好品质！
因为，世上有两种人：一种是幸运的人，另一种是不幸的人。幸运的人应该照顾不幸的人，这，是他们的职责！
请不要再让我们共同的世界缺少关心！
