笑归笑,我的脑海里却不由得浮起一个巨大的问号:书上说蜗牛是有眼睛的,但蜗牛的眼睛在哪儿?我怎么看不见它呢?为了解答我这个疑问,我便做了一个实验。
第一个实验目标是蜗牛的上身。因为许多动物的嘴巴都在上身,不知道蜗牛的嘴巴是不是也在上身呢?于是,我便找了一只大一点的`蜗牛,把它放在菜叶的旁边。只见它慢吞吞地爬到菜叶上,又慢吞吞地找嫩叶,然后才慢吞吞地吃起来。见他吃得津津有味,我才悄悄直起身,朝我“印象”中嘴巴的位置看去。但放大镜中的蜗牛上身周围,除了细小的条纹外,没有什么像眼睛的。
第一次实验——失败!
第二个实验目标是蜗牛的触角。因为每一次它吃菜叶时,总是要用触角去碰碰,不知道那是不是蜗牛的眼睛呢?于是,我便又找来一只蜗牛,把它放在菜叶子上,看它是不是像我想的那样,吃菜叶时总是要用触角去碰碰。
果然不出我所料,那只蜗牛爬到菜叶上后,便用触角碰了碰,我用放大镜看了看,只见触角顶端有两颗圆圆的眼睛——眼白中间有一点黑圆点。我又观察了其他蜗牛,也都是这样。
第二次实验——成功!
真高兴,我发现了蜗牛的眼睛,在触角的顶端。
世界上有很多的美丽正在等着我们去发现。它或许是心灵美,或许是外貌美。外貌美虽然有时候被衣衫褴褛掩盖,但还是能看出来;心灵美需要观察,它不会被脏乱不堪的衣服掩盖,穿着华丽也不一定心灵美。
在《开学第一课》里,讲述了跳水冠军有事要游泳一万米的不容易、吴斌司机舍己救人的光荣事迹……其中,我印象最深的还是一个在海拔1800多米的地方教书的邓丽老师和她的学生们。
那所学校没有英语课,没有美术课……可是,邓丽老师去到那里之后,给学生们上了他们前所未有的课。
可是后来,同学们担心邓丽老师会被调走,于是想方设法让邓丽老师留下来。他们编歌曲、画画……他们说,就算用尽世界上所有的办法,也要让邓丽老师留下来。终于,他们用美丽的方法留住了美丽的邓丽老师。
看了《开学第一课》,我感慨万千。美丽的宇航员姐姐告诉我:不要等失去了才懂得珍惜;美丽的.叶诗文姐姐告诉我:要成功不容易,但是努力之后成功了,这种喜悦是难得的;美丽的邓丽老师告诉我:要微笑着面对生活,幸福靠自己,要看自己对幸福的定义;美丽的吴斌叔叔告诉我:助人为乐是一种美好的品德,为民牺牲是光荣的……
我以后要创造美,传递美,发现美。我要用一双发现美丽的眼睛来看世界,发现更多的美!
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
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。
掌声是对别人的肯定。
一次文艺汇演,各班的演员们在台上都尽力做到最好,他们都把往日辛苦练习的成果很好地发挥出来,他们都希望可以为班争光,希望获得同学们热烈的掌声,但结果却是令他们失望的,除了自己班的几个同学鼓掌外,基本上就没有人鼓掌,这样也许会使他们觉得:难道我做得不够好吗?假如我们给以他们热烈的掌声,他们一定会做得更好。到他们获奖时,仍是听不到热烈的掌声,即使听到,也是微弱的。为什么我们就不能以热烈的掌声去鼓励他们呢?肯定他们的表现是好的呢?
掌声是一种给人以信心与勇气奋勇前进的`力量。
800米跑不及格的同学在一次在跑道上奔跑,时间一秒一秒地过去,一个女同学在快到达终点时跌倒了,她突然听到一阵热烈的掌声,她抬头一看,她的好朋友正以热烈的掌声与一阵“加油!加油!”的欢呼声给予她勇气,“起来吧,时间快到了!加油!”她顿时充满了信心,尽管脚跌痛了也尽全力爬起来,冲过了终点,时间刚刚好,他及格了!同学们又以热烈的掌声祝贺她。
掌声有时也被不道德的人用来侮辱别人。
俗语说:男儿有泪不轻弹。而这天,却有一个在学校里从没哭过的男同学居然趴在桌子上哭起来了。这是什么回事呢?原来,在下课时,不知是谁在教室门前放了一块香蕉皮,在他走进教室时,就中招了,跌了个四脚朝天,同学们全都哈哈大笑,竟还有人使劲地鼓掌,他因受不住同学们的侮辱而哭了。往往有些人看到一个人被人捉弄时,总会鼓起掌来,这不是对人的一种侮辱吗?他们为什么不去帮助被捉弄的人,而是火上加油,帮助捉弄他的人继续伤害他,他们不觉得可耻的吗?
我们的生活的确非常需要掌声,需要鼓励人的掌声,需要能使人奋勇前进的掌声,需要令我们的生活更美好的掌声。
