光阴似箭，日月如梭。不知不觉，现在已是21世纪了，科学在飞速发展，人们生化水平也提高了。现在，在大城市，差不多家家户户都拥有一台爱不释手的东西——那就是电脑。自从我家有了电脑，可以说是发生了翻天覆地的变化，且听我慢慢道来。

我现在已是一个初中生了，在学习这方面也少不了这个好帮手——网络。以前只要老师布置一个查资料的作业，我不是要跑到书店去寻找答案就是在家翻很多书，有时不仅还查不到呢。唉!真是太麻烦了。而现在呢?可就与众不同啦!每次老师叫我们查找课外资料，我只要轻轻松松运用电脑，鼠标一按，键盘一打，就很快能查到了，多么快捷呀!这样，不仅提高了学习效率，还让我们熟悉了电脑。多么方便呀!瞧，网络改变了我的生活，让我生活在一个方便快捷的世界里!

三年级的时候，妈妈为了让我提高写作水平，不仅买了许多的书，还在作文网上为我注册了一个用户。从此，我可以在网上发表文章，写日志，发图片，与各地的同学交流写作方法。作文网上经常举办一些写作活动，如每月的征文、“PK”赛……如果你在这些比赛中得到前三名，就能获得一份精美的礼物。我也很积极参加这些活动，从以前到现在，我参加过许多话题作文：创新、冬天、运动会、趣事……也曾拿到过礼物，这不，上次的话题作文“创新”，我又拿到了第一名!在这些活动中，我不仅提高了写作水平，结交了朋友，还获得了许多乐趣。瞧，网络改变了我的生活，让我生活得多姿多彩!

每当我写完作业，便会打开电脑，开始我的有趣生活，在那里，我感受到欢乐;在那里，我感受到胜利的喜悦;在那里，我学会了分享;在那里，我开动了脑筋……瞧，网络改变了我的生活，让我扩展了视野!

网络，改变了我的生活，让我生活在一个方便快捷的世界里;网络，改变了我的生活，让我生活的多姿多彩;网络，改变了我的生活，让我扩展了视野!

New year is coming.Spring festival is the most important festival in China.Besides celebrating it,Id like to make some new year resolutions.

First,I need to improve my English in 2009,especially to practice speaking.Maybe I can ask my English teacher to help with my oral English.

In the end,I will do more exercise this new year to keep healthy.I like basketball very much,so I can play basketball with my friends to become healthier.

众所周知，《水浒传》《西游记》《红楼梦》《三国演义》是中国的四大名著，其中以《红楼梦》的文学造诣最高，但是我却独爱《三国演义》中的英雄人物，他们不仅是在战场上英姿飒爽还有在政治上的勾心斗角，以及在谋略上的各抒己见无一不深深的吸引我，然而更多的是情节上的遗憾在我心中常驻。

刘备本是中山靖王之子，他品格高尚，拥有高贵的身世，以及温和的性格，使他广结良才，再加上他求贤若渴的精神，更是给他招揽了不少人才，昔水先生曾言“伏龙凤雏两人得一可安天下”而刘皇叔两者皆得文友诸葛孔明，武有五虎上将，而他仍然未能完成霸业兴复汉室实在令人遗憾，关羽杀颜良，诛文丑，更是对刘备推心置腹，昔日曹操与把它为其所用，但当他得知刘备尚在人世过五关斩六将在古城与兄长相会此等虎将何愁大事不成，再说刘备本身在曹操煮酒论英雄中把他的智谋临危不惧而他却不能平定中原实在令人费解，同时也让人遗憾。

世人评价诸葛亮鞠躬精粹，死而后已，但是我却认为他是愚忠，他胸怀大志足智多谋他对刘备忠心耿耿，但对阿斗却也尽心尽力，凭他的聪明才智本早可以一统天下，怎么会只落得个三分天下的局势，诸葛亮一生很小心，除了空城计外，每一计都经过一番周密的考虑，然而却派马稷去守街亭，连司马懿都能看出他一向纸上谈兵，难道心思细腻的军师会不知道？杀一个马稷只能保住军纪却无法守住街亭！

世人皆称曹操为奸雄，挟天子以令诸侯，但在种人中，也只有他能承担起奸雄二字，曹操本事大局已定，在赤壁之战却把所有的物资被诸葛亮烧毁，他一向多疑怎能听从一个奸细的话，再说草船借箭难道他就想不到用火箭去射杀敌人吗？

《水浒传》中写尽英雄豪杰，西游记中皆载妖魔鬼怪，红楼梦泪谈儿女情长，而我独爱《三国演义》中的不解与遗憾。

日新月异的今天和十几万年前相比，我们是至高无上的，和几千年前相比，我们是居高临下的。由从前的马车到现在的汽车、火车、飞机；由从前的煤油灯到现在的白炽灯；由从前的老电话变为现在的手机。这些变化无时无刻都在影响和改变着我们的生活。

现在的智能手机给我们带来了很多好处：老师利用手机上的软件给我们留作业，检查作业完成情况，及时跟家长沟通我们在校情况。学生们也不会因为没记清作业而被批评，随时打开手机就可以查看。

同时，手机还解决了以前人们通信难的问题。以前给家里或朋友都是写信互通，有的偏僻的地方甚至没有邮局。现在一个电话打过去，随时都可以跟家人和朋友通话，还可以视频聊天。

但是，手机也给我们带来困扰及危害：手机游戏无时无刻都在吸引着中小学生甚至成年人。有的玩游戏忘记了学习，有的玩游戏忘记了工作，有的甚至连饭都顾不上吃，影响了自己和家人的生活。很多孩子也因为长期玩手机游戏造成眼睛近视，还有的走路、吃饭玩手机，因此出了车祸。

科技在发展，好多东西都具有两面性，我们要正确认识利用，避免坏的方面影响，就可以造福人类，让生活变得美好。

life in the city is very different from life in the villages and on the farms. people in large cities are much more careful to respect the privacy of the individual. sometimes this feeling seems to be one of indifference, but it is a convention of city life to curb ones curiosity about the personal affairs of strangers. villagers and farmers are likely to show a great deal of interest in all their neighbors. opportunities for bright young people are greater in the cities and there has been a steady stream of hopeful jobseekers from the villages and farms to the large metropolitan areas.

人工智能越来越接近现实生活，智能家居已经进入现代城市，越来越接近智能生活，智能生活就像有个机器管家一样，只要一句话就能为人们所服务。

现在某网购平台天猫精灵卖的的特别火，因为智能，因为有趣，因为方便，整个套装包括插座、灯泡、遥控器、空调、电水壶等一系列智能产品，让这些家居动起来只需一句话，系统识别语言进行控制家居。

随着科技越来越发达，互联网、物联网逐渐与更多的家庭产品联系起来，只需要一台联网的手机就能完成人们所要做的事。

智能越来越发达，人工智能取而代之是更多的劳动者，每一次科技进步都会有一部分职业进行裁员，需要人劳动的地方就会越来越少，所以我们要想不被社会淘汰，就必须学一些特殊技能，学好更多的知识，做一些机械所不能完成的事。

尤其是在这几年，在国家领导正确的带领下，与多边国家合作，学习国外先进技术，创新出新的科技产品。如今无人超市，无人驾驶，中国高铁，都有明显的成就，有的先进技术已经达到世界前列。

这些智能，这些技术，都将计入新时代下新的征程带来的新成果。

而今年又称为5G元年，中国网络速度也将会大大的提高，电视8K的观看，3D打印机，3D模拟世界带上眼镜就能实现。我们都将会享受科技给我们带来的幸福感，智能带给我们的亲切感，祖国带给我们的安全感。

智能改变生活，科技改变世界，我们所生活的家园会因新时代的到来带来更多的惊喜，更多的便捷，更多的幸福。

When weekends come, everyone is happy about that, because they don’t need

to work and can do what they want. Some people will choose to stay at home and

watch TV all the time, some will choose to go shopping, while for me, I’d like

to go out. I want to see the different things and refresh my mood. I always make

some plans for my weekend.

Sometimes I will ask my friends to go to watch the movies or we go out for

the gourmet. I like to see movie so much, watching the movie is like reading a

book, my mind will gain things and I will feel satisfied. Eating the delicious

food is the things I will do mostly, I like to find the new food, and ask my

friends to enjoy it. We will talk happily while eating the delicious food.

so I will go hiking with my friends on weekend. We will bring little food and

take a backpack, heading to the park or beautiful mountain. We can enjoy the

beautiful scenery, at the same time, to exercise our bodies.

When I was young at high school,I couldnt stop dreaming about my college life again and again.Suffering too much pressure form college entrance test,I always admired college students for their relaxed life in college.

In my personal opinion,living in university is  an enjoyment.Every day we can open our eyes naturally,and put on clothes in our own style without warring about teachers rigid control.Communicating with great master is no longer beyond our reach.Each course we take can be a feast for our mind and soul.After class,we will lead a rich and colorful life filled with various leisure activities such as .Library in  university is another factor I pursue.I think its an access to enhancing our comprehensive abilities to read even just scan all  sorts of

writings.Whats more,we will have so much disposable time that we can do whatever worthy.And our contact group will be extended signally via organizing and participating many activities.All in all,I once imagined that I can live a life that is substantial but meaningful.

However,I just have to admit that what I just describe is really dream.Now living in SD I cant figure out what I pursue and make a feasible career planning.So many young cynics in this schoolyard  argue for something meaningless.Worse still,the academic atmosphere has already done with nothing left.I havent found a busy but rich thing to try my best.As a matter of fact,I even cant choose a lifestyle I prefer.What a tragedy it is between dream and reality.

When someone disagrees with you or offends you, don’t lose your temper. Why? Because it is of no use to do so. You ought to (should) be patient and keep calm lest you should quarrel with him. You must know that patience is not cowardice, but a virtue. I hope that everybody practices it.

In addition, patience will also bring us success. When you meet with difficulties in your work, it is no use losing heart. You must keep on fighting until (till) the final victory belongs to you.

I really had a busy and happy winter holiday. I did my homework and helped my parents with the housework every day. I like drawing so much that I spent lots of time drawing pictures and read books about drawing every day. I sometimes went to the library to read books and surfed the internet.During the Spring Festival, i visited my grandparents, friends and relatives. We really had a great time together. I prepared for the new lessons and read English,too. I really enjoyed my winter holiday.

我寒假过得很忙很快乐。我每天做作业并帮助父母做家务。我是如此喜欢画画以致于我每天花大量的时间画画和看绘画方面的书籍。我有时去图书馆看书和上网。春节期间我去拜访我的祖父母和亲朋好友。我们一起很愉快。我也准备新课程和读英语。我非常喜欢我的寒假。

When winter holiday is around corner,I have so many plans,but now I just like coughpotato.

My sister and I sleep in the morning,my parents get mad at us.They force us to get up,we lock the bedroom door until we are both hungry.Ha...

Because of final exams,our skin in bad condition,my sister said that sleeping is good for skin.Yeah,female do care about their appearence all the time.

Afternoon belongs to friend.Call them out and go shopping toghter.We gossip all the people we know.This feeling is so cool,you may find that friend is so important in the world,no on can live without them.

My day is simple.

Fortunately, more and more people have realized the serious situation. Many countries have passed laws to prevent the environment from being further polluted.

Definitely, controlling the increase of population is one of the most efficient ways.

However, in future more efforts will be needed to win the battle against pollution, The laws controlling pollution must be strictly enforced, And above all, attention should be paid to the education of the people so that everyone will show his concern about environmental protection.

随着时代进步科技的发展，各种各样的科学软件产品开始出现在人们的视野，我们这个年纪的孩子们也对这些东西有了浓厚的兴趣，有的会抢红包，有的会打游戏，有的会制作小电影嘿，我真幸福！生活在科技高速发展的新时代。

我想奶奶啦，妈妈我们什么时候去看看奶奶啊？每到寒暑假我总是磨着妈妈去北京，哎呀，奶奶在那么远的地方，咱们这么千里迢迢去多麻烦，还要辛苦姑姑他们带着我们出去玩儿，看你这小样儿？来来来，妈妈教你看个好东西是什么是什么！不等妈妈话完，我便急不可待地想知道。

你看，这智能手机不是有微信吗，咱们先打电话跟奶奶说加她微信，这样就可以通话可以见到奶奶啦！妈妈笑嘻嘻地教我，咦，有这么神奇吗？我这心里的疑问可大得很？不一会儿，我们就打通了奶奶的电话和奶奶加上了微信，奶奶，你看到我了吗！这才加好微信，我就兴致勃勃地开始比划着，你看，这么一按，你马上就能见着奶奶了！妈妈这手起刀落的一个指头点下去，奶奶慈祥的笑脸咻地一下就出现在手机屏幕上，不一会儿姑姑也来了，简直太幸福了！姑姑，你能看见我吗，你能看见我吗！我在手机的这端亢奋地喊着。姑姑看见你啦！姑姑在手机的那头向我挥了挥手，妈妈，你这是怎么做到的？还能隔着手机就能看见远在北京的奶奶，这样以后我是不是想奶奶了随时就能看见奶奶呢？是呀，随着科技的发展，微信开始被广泛使用，你看，这打过去奶奶要是接通了，我们就能看见她啦！原来是这样，我再也不用天天‘求着’妈妈了，哼，让她还用完成各种练习‘要挟’我！我在心里自个儿悄咪咪地乐着，。嘿，朋友们，我们真幸福！这科技的发展可真了不起！

生活在这样一个科技发达的时代，虽然也会出现这个不合适，那个不适应，但是对于我们生活的便利总是会愈来愈多。随着高水平的科技发展，我们越来越离不开手机、电脑，、互联网总有新闻说现在科技发展的太多太神速对青少年的身心健康不利，总会有孩子走上歧路，但是只要我们善用科技，科技的发展就会令我们的生活更加阳光向上更加璀璨多姿。

嘿，我真幸福！在这个科技飞速前进的新时代健康成长，在美好的科技时代增长自己的见识，增强自身的技艺，探索科技中无穷无尽的奥秘！

七十多年前，爱因斯坦曾致信罗斯福总统。信中提到，在“制造一种极有威力的新型炸弹很快就能变成现实”的情况下，希望政府“如有必要，应迅速采取行动”。之后美国率先造出了原子弹，然而原子弹却给人类造成了史无前例的破坏。当年爱因斯坦提出质能方程时他又怎会想到这个公式会成为千万人痛苦的来源。一直在致力于世界和平的爱因斯坦，晚年无比后悔当初写的那封信。甚至在他去世的那个月，还与罗素发表了《科学家要求废止战争》的宣言，敦促各国政府承诺绝不在世界大战中使用核武器。在那个年代，人类社会笼罩在硝烟的阴霾下，科学技术一度起了反作用。理论科学的发展，竟然导致了人类社会的灾难。

三十多年前，比尔盖茨从哈佛大学退学。之后创办了伟大的微软公司。他当初的梦想是让每个人家里都有一台计算机。后来他成了世界首富。在那个年代，信息技术革命的浪潮不可阻挡。科学技术极大地推动了社会的进步，社会发展在各方面达到了前所未有的高度。

然而几年前在即将退休之际，比尔盖茨却将全部财产捐给了比尔梅琳达基金会用来回报社会。在哈佛大学毕业典礼的演讲上，他提到：“我离开哈佛的时候，根本没有意识到这个世界是多么的不平等，根本不知道发展中国家里有无数的人们生活在无法形容的贫困和疾病之中。我花了几十年才明白这些事情。”于是他的梦想改变了：“事实上有条件上网的人只有总人口的六分之一。很多人连面包都吃不上，那些计算机又有什么用?”

这就是当今的世界。它在摆脱了战争，摆脱了落后之后，迎来了新的挑战。在这个新技术加速发展的时代，不平等是这个社会面临的最大问题。因为不平等，才会出现目前地球上数以万计的儿童面临死亡，美国宇航局却有数十亿美元的经费向火星航行的情况。科技发展曾带来痛苦和灾难，也曾为无数人的生活带来方便。然而如今，在社会与科技都高速发展的时候，问题变得复杂了。

我们所谓科学与技术，其实是有区别的。科学的目的在于探求真理，这是意义高于生活的象牙塔。而技术却是为了改善生活，它更多地服务社会，有着实际看得见摸得着的作用。但同时科学与技术可以相互促进。在望远镜设备不发达的从前自然没有现在掌握的宇宙知识丰富。可同时是理论知识的进步才导致了望远镜的不断更新。所以科技合一才能极大地推动人类的发展。这个推动力，是长远的一个积累。历史之所以有其意义，正是因为时间的沉淀与证明。科技也是这样。可能现在看似无关的研究对解决那些问题帮助不大，就像理论先要影响技术才能继而影响生活。表面上科技对这些不平等熟视无睹，但终有一天——即使我们看不到这一天——就像几千年的科技发展才形成了今天的生活，但我们依然坚定地相信：科学技术会解决而且能解决这些问题。科技对生活的影响是长远的。

而人文社会的事业，则更着重于当下的意义。正因为有了那些有责任有勇气的记者奔赴贫困战乱的地区，我们才能了解难民的生活，真正触及他们瘦骨嶙峋下那脆弱无助的心灵;正因为有了那些为自由与解放事业而奋斗的领导人，他们的人民才能摆脱枷锁，获得重生，获得希望;也正因为有了那些投身慈善去帮助同胞的公益人物，从自己做起却不断影响身边的人一块做，从身边做起却让这个社会也更多了份爱心与责任。正是因为有了这些人文领域的社会各界的人士，他们发出了自己的声音，作出了自己的行动，才给这个社会树立了榜样，让我们开始关注世界的改变，并试图用每个人的力量去影响世界的改变。

与此同时，人文社会潜移默化地受着科技的恩惠。是信息的传递让这一切发挥力量。可能非洲的某个地方疟疾横行，中东的某个国家暴动袭击。我们在遥远的中国几小时之内就能得知具体情况。这个世界变得越来越小，是为了让人们的生活变得越来越好。当社会进步了，拥有了人文精神，科技也会发展得更为稳健。当那些宇航员飞上太空，看到美丽的地球，一定会知道这可爱星球的宝贵。人们那时看着他，也一定会明白探索宇宙的意义。

“改变世界的阻碍，并非人类的冷漠，而是这个世界实在太复杂。”确实是这样，我们并不是不在乎，而是我们不知道怎样去做，从哪里做起。但是我相信，科技的力量，人文的力量，一定会让我们的生活越来越好。

健康的生活习惯对于成长中的我们是非常重要的。你认为健康的生活习惯应当是怎样的呢？请根据下面的信息提示，写一篇短文，首句已给出。

眼下，科技越来越来发达，人们逐渐进入了信息时代。现在就让我来介绍“信息时代”标志性的物品之一——手机。

手机的外型小巧玲珑，很轻便。它的功能可不少，能发信息、拍照、查日历、上网、录像……

其中功劳最大的，也是最常用的就是快速的发信息和通话了。要想在古代，人们见一次面，传递个消息，都得用上几天或更长的时间。还有写信，你在东城，我在西城，从东城送一封信给我，有时要十天半月甚至几个月的时间。多漫长的等待呀!

可是，自从有了手机，生活就改变了。有紧急情况，不用急，只要发一条信息，也就几秒的时间对方就收到了。要在哪里碰个面，只要打个电话就行。多快捷呀!让我们节省少了许多富贵的时间。

当然，手机并不代表所有科技。现在的因特网呀，人造通讯卫星呀等等都让人类的生活更加舒适，更加便捷。总之科技让我们的生活改变了很多。
