Dear dad,
It’s so late,almost 11:00 at night.Have you entered into the sweet dream yet?I haven’t seen you for a long time.I miss you so much.Can you hear my sincere words?Maybe you’ll never know I miss you so much!
Do you still remember the happy days when we were all together?During those days we were full of sunshine.You and mum often took brother and me to the park.We always saw the ice-cream tear.Sometimes,you stayed at home and cooked some delicious food for us.We often waited for you and played with you.You could lift me very high.We always had a good time.You also concerned about my lesson.But you have never chastised me and lectured me.You were full of thoughts for me.What’s more,you were my best father in my heart.You were the envy of my friends.I was happy for a long time.But now,all things have changed.You can’t take care of me.You aren’t at home all day.Sometimes,I go to bed late,but I still can’t see you.Are you busy?No!you often play cards with your work friends in the factory.So you can’t go back home early.I’m angry to hear that!Do you know?If you don’t come back,we’ll worry about you.I often see you and mum should divorce in my dream.I’m very scared,because I want to have a happy family.I can’t control my tears and often suffer from insomnia the whole night.
Dad,I want to see you and talk with you.But I have no courage to tell you.But I hope you can care our family.Dad!Could you hear my voice?
Hope you keep healthy and best wishes.
人们都认识电脑,那对电脑的认识又有多少呢?听我的介绍吧。
电脑,又名计算机,这是一种能够按照程序运行,自动、高速处理海量数据的现代化智能电子设备电脑由硬件和软件组成,没有安装任何软件的计算机称为裸机,常见的型号有台式计算机、笔记本计算机,较先进的计算机有生物计算机、光子计算机、量子计算机等。
随着科技的发展,电脑已有了许多种类型,以前的人们习惯地把计算机分成巨、大、中、晓、微五类,即巨型机、大型机、中型机、小型机、微型机。现在人们把计算机分成服务器、工作机、台式机、便携机,手持设备五大类。
电脑非常方便,歇息时有困难可以上网查资料,空闲时可以上网找同学聊天,需要物品时可以网购。有了电脑整个地球就变成了一个小村子,人们可以互相沟通,不管在天涯海角都可以联系。不过任何事物都有两面性,电脑也不例外,如果一直坐在电脑前面就会近视,有些人沉迷网络,得了“网瘾”。
电脑给了人们便利,但同时也带来了危害。
我家有一台联想笔记本电脑,长约30厘米,宽约24厘米,厚约6厘米,和一本大笔记本差不多。它虽然是电脑的微缩型,但价格可比普通电脑贵了差不多一倍,可功能却一点都不少。
笔记本电脑通体漆黑,像一块黑绸缎一样。面板上有一块legend的联想标志闪闪发光。主体四周有一些可以打开的小门,可以放入软盘、光盘;还有许多输入,输出口,可以插入电线,连接许多复杂的小配件,如稳压电源,耳机,“猫”(调制解调器等。
打开盖板,只见盖板里面一块微型液晶板映入眼帘,原来这就是显示器。主体上面是排列非常紧凑的键盘,键盘的下方有一个感应器,具有鼠标的功能。键盘的上面有两个喇叭,以至电脑的背景音乐十分宏亮。左侧面还有一个开关,这是电源总开关,控制着电脑的开和关。右侧面还有一个插口,是鼠标插入的地方。我非常爱用它来休闲。打开它,我就有一种新鲜感。用鼠标在因特网上漫游,可以看到很多奇妙的趣文,十分舒坦。它还能帮助我学习文化知识。记得有一次,我在做数学题时,遇到了一道难题,便请教这位“老师”。它先“讲”出解题的思路,然后列出几种解题算式。让你选择一种正确的。你如果答得好,它还会放一段动画片奖励你呢!有时我也玩游戏,一个人太没意思了,它就会和我“并肩战斗”。
这个电脑可以储电,因为主体体中有蓄电池。白天不在家,就插上插头,给它补补“力气”,也挺有趣的。充满电的它无需电源插头,直接可以使用。与普通电脑相比,它体积小,便于携带,所以人们称它“便携式电脑”。
笔记本电脑是我的好老师,也是我的好伙伴,更是世界高科技发展的象征。
Yesterday was Father's Day. I had planned to give my father a present. But I didn't remember it until in the morning.It was too late to post a card to him. So I decided to buy something. When I was in the department store. I found it was not easy for me to choose something right for him. Suddenly I
got an idea. I ran home and opened my computer. I made a beautiful card and mailed him through the Internet. then I began to make supper. When father came home, he was very glad to find a big meal on the table. then I asked him to check his e-mail. He was amazed to find a beautiful card in his e-mail-box.
What a wonderful surprise!
它,为人类的生活带来许多的方便;它,为人类解决各种不同的问题;它,是现代人最好的朋友;它,就是生活中不能缺少的物品─电脑。电脑的用处有很多,例如:查询资料、看新闻、听音乐、使用文书工具做报告……等,都会需要使用到电脑。
在我写作业时,电脑无意间成了我最好的朋友,协助我完成一样样艰难的任务。有时需要找图片、有时需要查询资料,电脑都能够一一克服这些困难来帮助我完成作业。所谓“成也萧何,败也萧何。”如果我们充分使用电脑,它就能成为协助我们的有效工具;相反的,如果只是利用电脑来玩线上游戏或沉溺于网路交友,那么电脑就会变成一个使人堕落的怪兽。
因为现代人依赖电脑的时间很多,与电脑面对面的时间也很多,因此视力保健就成为一项重要的课题。第一,我们面对电脑屏幕应该要保持适当的距离。第二,我们使用电脑三、四十分钟就要休息十分钟,如果不这么做,就容易造成视力衰退。第三,使用大一点的屏幕,因为使用大一点的屏幕不但看得比较清楚,解析度也比较好。以上几点是使用电脑时大概要注意的事项。
现在,电脑的应用技术还在提升,科技越发达,电脑的\'实用性就会越加提升,人类就可以使用电脑来帮助我们处理更多的事情,电脑就显得更便利。我们能够生在二十一世纪的现代,真是太幸福了!
