生活中无法缺少梦想的作文【一】
21世纪的汽车种类繁多，是人们出行的好帮手，因为汽车给人们出行带来了许多方便，所以大部分家庭都有了汽车。但，现在的汽车还有许多缺陷，我想象中未来的汽车是这样的。。。。
21世纪的汽车有很多安全隐患，每年都有若干人丧生于交通事故，交通事故多次发生使多少的家庭伤心欲绝啊！但未来的汽车却不会这样，假如周围有行人的话，它会在5秒钟内告诉你并采取相应制动措施；有红灯时，它会自动停下来；当你违反交通法规时，他会提醒你，如果你没有及时调整，它会自动替你改正过来；如果与其他车辆发生碰撞，他会在第一时间拍下那辆车的车牌照并自行拨打110、120电话，同时还能自动识别有无人员受伤，如有，则会使用机械手拿出急救包提供给第一现场救护者使用；当警察赶到后，它会全程拍摄事故现场..........这样，会大大减少交通事故发生的可能性，降低事故的伤亡率。
说到这儿，你一定会想：功能这样齐全的车，一定是排量大不环保、又相当昂贵吧！那么，你错了。它不仅环保，还很便宜。它用太阳能充电，不会排放任何尾气污染，而且其本身的制造材料都是循环利用的。把报废的汽车送到汽车厂回收，再加一点钱就可以更换新车了。
这辆车还很实用，可以上天飞行，也可以下海遨游，出去游玩时它会告诉你哪里好玩，你只需要同意它的建议，行程导航立即会设好；如果你告诉它你饿了，它会自动排查联系最近而且又不用排队等候的便利店，直接付钱吃饭；如果嫌到目的地购买门票太烦，它会利用卫星无线网络自动为你订票，节省了许多时间。
未来汽车还有很多好处，我就不再一一介绍了，相信在不远的将来，我们就会驾驶上这种汽车的。
生活中无法缺少梦想的作文【二】
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
生活中无法缺少梦想的作文【三】
汽车几乎家家都有，可是汽车一多，会给交通带来不便，汽车的气会严重地污染环境，我梦想中的汽车比现在的车完美多了。
现在每一辆车都需要有停泊的地方，我的车可以收缩，这样就可以大大节省空间，省下来的地方可植树造林。如果遇上堵车不用担心，我的车会伸出一对翅膀，让你能在天空中自由飞翔。我还在车的底部设有一个吸尘器，它不但可以吸除地面上的灰尘和树叶，而且还可以将它们变费为宝地转化为能量供汽车行驶，这样不仅保护了环境卫生，而且大大节约汽车能源地消耗，真是一举两得啊！
如果你在野外过夜，汽车会变成一个小房子，这个房子会与周围的事物融为一体。比如：在乱石堆中它就会变成一块大石头，这样就不会受到各种野兽地攻击，屋子是密封的，不会有蛇虫入内。当你开夜车困了想睡觉，可以在电脑中输入目的地，按一下“自动驾驶”就可以了。为了进一步绿化空气，我在汽车的排气孔处装置一种设备，它可以在吸收二氧化碳的同时释放出新鲜的空气。不好有位新手要碰车了，何必这么大惊小怪呢？我的这款车有特殊的安全气囊，在汽车受到磋撞时就像碰到海绵上一样根本不会受到伤害，可以说是毫发无损，我还为它设制了特定儿童锁，只要有儿童在车内，车门会死死锁住，这样儿童在车内很安全。
对了这款车的名字叫“21世纪梦想车”，希望这种车早日被科学家们制造出来，造福人类，造福大自然。
