To see a world in a grain of sand,
And a heaven in a wild flower,
Hold infinity in the palm of your hand,
And eternity in an hour.
一沙一世界,
一花一天堂,
手中即无限,
永恒亦短暂。
随着时代的发展,科学的日新月异,电脑已经进入了寻常百姓家。如今,我们已经走进了一个信息时代。网络已经成了人们生活中必不可少的东西。我们在上网的同时,要做到文明使用网络,上文明网,做文明人,使用文明网络语言。
但在网络中,有一些诱人的游戏和聊天网站,给我们在学习之余带来了许多乐趣,却也给我们带来了一些危害。我听说有的'同学因为沉迷于网络游戏而无法戒掉“网瘾”实在是太可惜了。我们作为一名小学生应该以学习为主,以适当的上网为副,不能整天迷恋网络游戏影响学习,到长大后会后悔一生的。
什么东西,都有它好的一面与不好的一面,网络也是如此。网络改变了人们的生活方式和学习模式。我们经常上网可以在网上寻找资料,在网上学习知识,爸爸妈妈有时还会在网上购物,在网上跟朋友聊天……有些不明白的问题我就登陆百度搜索引擎查找。有一次,我的数学作业有一道题目不会做我便到百度里去搜索,果然找到了答案,不但让我顺利的完成了作业,还学到了解题思路。
网络是非常美好的,我们要吸收有营养的东西,没有营养和不健康的东西我们要自主自觉的屏蔽掉。所以,我们每个人都因当遵守<<全国青少年网络文明公约>>:“要善于网上学习,不浏览不良信息;要诚实友好交流,不侮辱欺诈他人;要增强自护意识,不随意约会网友;要维护网络安全,不破坏网络秩序;要有益身心健康,不沉溺虚拟时空。”
Recently, there is a popular saying: the world is so large that I want to have a look! As more and more people travel around during their holidays, tourists have brought large sum of money to the local people.
However, too many tourists also bring some problems to the local life. The most serious problem is the pollution caused by the uncivilized tourists. It’s reported that there were thousands of tons of rubbish left after the flag-raising ceremony on Oct. 1st. The uncivilized tourists left their rubbish wherever they go, polluting the local environment. Another problem is the traffic jam caused by so many tourists.
Tourist can promote the economic development of the local areas, but the pollution caused by those uncivilized tourists has brought severe problems. The local tourist authority should set up relative laws to protect the environment of the local areas, and every tourist obey the laws and help to make the places of tourist more beautiful!
