2013 —— 转折点

世界, 科技

北京市丰台区云岗中学高二年级 宋广皓

       不知不觉中，来到方舟上已经快半年了，这里的水比人的血还要珍贵。海水淡化机组即使二十四小时不停地转，也永远没有填平过如此巨大的供给缺口。然而比这更加棘手的是：剩下的粮食只够维持两年，那时，我们将穷途末路。
从今天的广播中我们得知，方舟正驶向距北极点一百公里左右的挪威斯瓦尔巴群岛，那里有一座大型的地下种子库，是科学家们专门为了预防全球性灾难而建立的。感谢上帝不仅给了我们方舟，还给了我们希望。另外方舟上的人会对做出这个英明决定的人感恩戴德的，虽然他未曾被人知晓。
想想一年以前，电视中还在不知疲倦地报道面临灭绝的动植物数字，我想如果电视机有思想的话，那么它也会发现一个现象——这数字从来只增不减。现在想想，我们一边乱伐森林，滥垦草原，这一切都只为了让一个叫GDP的数字更高一些。而另一边却用这数字来“吓唬”自己，何必呢？1996年，当我还是个婴儿时，国际保护自然联盟做出的报告就写道：地球上经人类影响后的物种平均灭绝速度是人类出现前的一百万倍。而一年后我不得不相信，因为事实就摆在我面前。忽然又想到了哲学中讲到的“量变最终导致质变”的原理，真是让人难以理解，如此简单的道理，那些叱咤风云的政客们却不懂。
当我正在房间里发呆时，方舟猛地一动，我一下子被甩到了床上，接着便收到了通知：

关于2013年太阳风的通知

       同胞们，经科学家们证实，2008年12月由美国宇航局预测的2013强太阳风暴即将到来。由于方舟上的防磁暴装置无法抵御，遂决定快速驶向挪威，在太阳风暴来临之前尽量将种子种植下去，以解决生存问题。

2013年9月9日多国联合声明

       看来再伟大的人类工程奇迹也拗不过大自然的脾气。由于地球防御太阳风的“铠甲”——磁气圈是从大气中“偷”走电子来维持自身存在的，而近百年来大气的质量每况愈下，使磁气圈越来越薄。终于，随着南极的臭氧层出现空洞，磁气圈也随之破了一个大洞，致使地球防御太阳风的能力降到了历史新低。能否在太阳风暴袭击地球之前将种子送到世界各地，谁也不知道。
而我们唯一知道的就是，当风暴到来时我们若还在海上航行，方舟便会无法操作，我们都将会成为历史的尘埃。
现在我能做的只有祈祷了。

后记：
三十年后的今天，我偶然发现了我的这篇随笔。后来，我回到了中国的土地上，但与以前不同的是，现在再没有国界，各国政要组成了联合政府，他们采纳了一个孩子的意见，将新政府命名为“地球联邦”。
由于没有了战争，没有了破坏与歧视，我们将自己与灾难前的人类相分开，作为另一个物种站在大自然的面前，我们给予了自己新的名字——新人类。
而2013年，被认为是新人类诞生的一年。
人类从此走向了另一条路。在孩子的课本上总印着这么一句话：如果你想活着，与其造一个方舟，不如把地球变成方舟。

Dinosaurs and their descendants

English Reports, 世界, 科技

Dinosaurs are ancient creatures, which lived on the earth millions of years ago. What is left of them now are bones which have been hardened over the years called fossils. Fossils are remains of living components, which have mixed with mud and soil. After a period of 6 million years the first humans appeared on earth. Over the years’ technology improved, and life became more and more complicated until today.

It is said that the only living descendants of these magnificent creatures are modern birds. Rumour is that dinosaurs evolved into birds. The first living bird-like creatures were called Archaeopteryx. Archaeopteryx had feathers but couldn’t fly. Instead they resolved to gliding from branches. For example, a dinosaur slowly grew feathers over a period of time. With these feathers they were able to leap from tree to tree. Slowly, these feathers evolved into wings and enabled the dinosaur to glide from one place to another. Over a period of time, these wings became better and the muscles became stronger, and they finally became the first birds. It is good if birds are studied carefully, and if they are, there is a chance that we may find out more about dinosaur bones. With the dinosaurs, there were also aquatic animals.

Today’s sea creatures, such as sharks, whales and fish, are descendants of these ancient aquatic creatures. The people who excavate and study about dinosaurs are called paleontologists. When we reach a higher level of technology, we might be able to extract DNA from fossils and recreate genetically engineered dinosaurs. If we can do this, we can even reverse the extinction of these great creatures.

Usage of Technology for Educating Children in USA Schools: A Bliss

English Reports, 科技

Technology has changed every aspect of our lives including the education system and the process of learning which forms an integral part of every individual’s life. Inculcation of technology in education has not only reduced the burden of the teachers and students, but has also made the learning process very interesting and easy to understand for the students.

Everyone seems to be fascinated by the usage of technological equipments used while teaching like projectors and smart boards. As per the data, the percentage of computer usage for teaching in schools has almost increased by 80% in the past one decade. Only 18% of public schools in US had computers for instructing the children in the year 1981 which increased drastically to 98% in the year 1991.

Teachers are well versed with the usage of technological equipments who help the students in learning the matter in a better manner. Children enjoy the audio and visual effect of the smart borads used by the teachers for teaching the students. The animations used for teaching various topics add to the interest of the students and makes them more inquisitive to learn more about the topic.

The fact can’t be denied that the inculcation of technology has helped both the teachers and the students. While the burden on the teacher is reduced, the efficiency of the students have also increased with the active learning process.

Now, the teacher is not the center of attention, but she acts as a facilitator or a guide and helps the students in getting the information in a better manner through technological methods. With technology involved in education, the students are more active in their learning. Usage of technology in the classroom gives opportunity to the students to be more interactive during the session and even clarify the parts with the teacher or ask her to repeat the instructions using the smart board.

According to the information provided by the teachers using latest technological methods for teaching students, students showed high level of motivation by learning using technological equipments. The main reason for this was their freedom from the normal classroom setting and the boring lecture sessions which couldn’t retain the attention of the students for a longer duration.

手机-优点

世界, 科技

相比西方国家，中国，作为发展中国家，各项科技发展起步较晚，但是，在快速借鉴西方发展国家的科学技术的发展成果的基础上，中国的科技进步十分迅速。尤其是中国的电信行业的发展，其成就令人鼓舞。

记得在高中时期，能拥有一部手机就是莫大的荣幸。那时候，诺基亚还是手机行业的领头羊，无论班上哪一位同学使用一部智能手机，其他的同学都会向他（她）投来羡慕的眼光。相比北上广，我所在的城市只是中国的一个小小的三线城市，因此，学生们都不知道“苹果”手机。而那时，也没有花样繁多的社交软件，QQ就是大家使用最大的聊天软件，手机的主要功能也只是看视频，玩游戏和通话。

现如今，只要你身在中国，无论你走在那一个城市，放眼望去，你可以可以看到大家都在使用各种智能手机，而且，“苹果”和“三星”这样的国际品牌在中国已经家喻户晓。如今，手机的功能也不仅仅限于通话和看视频等基础功能。各种APP 的应用已经普及到大家日常生活的方方面面。购物支付，医院挂号，水电充值等等生活琐事都可以运用手机解决。从2G到3G，3G到4G，每次数据网络的提速用时不到一年。也就在这几年信息化浪潮之中，我们许多优秀的企业也渐渐崛起，例如“华为”“中兴”“小米”等，不仅在中国的销售市场十分火爆，在海外市场，我国的企业也都占有重要的一席之地。
