Computer is a very useful machine. Some of them are big, but some of them are very small .Many people like playing computer. Computer has many functions, so that people can do a lot of things by computer, like watching movies, listening to the music or playing games. It can make our lives very colorful and convenient. Various people can make good use of computer. Children can use computer to learn and play games. Parents can use computers to work. I think computer is a kind of wonderful and interesting machine, so I like computer very much.
电脑是一种很有用的机器。有的电脑很大,但是有的'很小。很多人喜欢玩电脑。电脑有很多功能,人们可以i用电脑做很多事情,比如说看电影,听音乐或者玩游戏。它可以使我们的生活充满色彩和便利。各种各样的人都可以好好利用电脑。小孩子可以用电脑来学习和玩游戏。父母可以用电脑来工作。我认为电脑是一种神奇有趣的机器,所以我很喜欢电脑。
“我以前是个性格内向、不敢积极回答老师提出的问题的孩子,但现在我也不知怎地,好像喜欢上了积极回答问题,每次老师一提出问题,我总是争先恐后的回答,以前的.我生怕回答错问题。”
记得有一次,老师提出了一个问题,我回答错问题了,老师又提出了一个问题,我心里有些犹豫,到底是举手呢?还是不举手?老师好像猜透了我的心思,说:回答错了并不可怕,可怕的是你没有勇气,不敢回答,听了老师的话,我渐渐地敢举手了。
一晃就是五年啊!在这五年里,我都积极回答老师提出的问题,如果现在让我改掉举手的“习惯”,那是不可能了,因为我已把它当成了我生活中必不可少的一部分,古罗马——西塞罗曾说过:有勇气的人心中必然充满信念。(罗·赫里克)曾说过:要想办成事,就得丢开胆怯,谁畏于启口请教,谁就得不到指教。这几首名言深深地刻在了我的心中,我永远也不会忘记的。
到最后,我想对那些没有勇气的人说,大胆天下去得,小心寸步难行。
终于又到了周末!周末在人们的脑海里是快乐而幸福的,因为可以不用去上班也可以不用去上学,家人可以团聚在一起休闲和玩乐。但是我的周末总是充满着遗憾,因为那些恼人的`作业让我无法尽兴。
假如这个周末没有作业,我就可以尽情地玩耍。我想去天津参观被称为“滨海之眼”的滨海图书馆,在书海中拾贝,而不用担心路途遥远而无法写作业的问题;我想和同学一起去公园骑车、“撕名牌”或者联机打游戏而不被家长催着写作业;我想看自己喜欢的书,想看多久就看多久,一点儿不受作业的干扰;我想下棋、画画等等,总之没有作业我玩什么都痛快。
假如这个周末没有作业,我就可以去看望我的姥姥、姥爷。今天是重阳节,我想去帮姥姥、姥爷做些家务,我想去给他们捶个背洗个脚,晚上吃一顿姥姥做的美味佳肴,夜里我可以和他们睡在一张大床上,听他们讲述他们年轻时候的故事,这将是多么幸福的周末呀!
假如这个周末没有作业,我会是一个好脾气的孩子。其实我的脾气并不差,只是经常在我玩到兴头上的时候,妈妈会问作业写完了吗,然后我会不情愿地放下手中的玩具被迫去写作业,这让我产生怒气积在心里,不知什么时候就会像火山爆发一样发泄出来,然后就会被爸妈一起批评。要是没有作业我哪会发脾气呀。
可惜这只是“假如”,我不得不从这白日梦中醒过来,接受这残酷的现实,继续赶着这周末的作业了。
物体在水中为什么或沉或浮?在我们的生活中经常会发现:巨大的万吨级货轮不知道为什么能浮在水面上?而一些极小的物品为什么能沉到水里?为了探索这些问题,我进行了更深入的观察、实验、分析研究。针对以上疑问我在家里做了一个实验:我用准备好的材料梨”来开始我的实验,因为家里条件的限制,实验只能在浴池里进行,同时我也收集了一些其它材料放在桌子上,包括橡皮、泡沫塑料、剪刀等物品,做同种物体体积轻重和沉浮关系的实验。
实验正式开始了,我把梨放入水中,当然在这之前我也有过猜测,这样大而重的梨究竟是浮的还是沉的,我拿起梨,要对它进行切割,因为梨比较大,我先竖切一刀,把梨的一半放入水中,结果出现的是浮的现象。
再顺手把拿在手上的半个梨横切,把上半部分放入水中,结果出现的是还是浮的现象。
这时,手中的那截的体积已经不是那样大了,我水平切,放入水中,结果出现的是反现象沉。
这个实验原本是很简单的,一直都没有太大变化,而这时候突然出现的现象马上吸引了我的眼球,这是怎么回事,刚才都是浮的梨怎么现在沉了呢?我的内心再次沸腾起来。
我随即再重新放入一次,所得结果还是沉。
到底怎么回事啊?我感到疑惑极了,大块的梨是浮的,小块的梨也是浮的,为什么偏偏会出现那一块沉的呢?我无法猜测得到,也没有找到什么依据。
带着困难,事后我进行深入的分析发现:原来主要是因为这部分沉的梨处于梨的下端,所以富含丰富的水分,也就是说,虽然都是梨的一部分,但是它跟其他部位的梨的密度是不一样的,这从刚开始放入水中整个梨的状态也可以看出,那时候它是浮的,但是是头部上浮的比较多,尾部下沉的比较多。以上的实验反映了一种科学现象,这种科学现象给予了我们启示:使我们找到了其他物体可以沉浮的主要原因是什么,通过查阅资料了解,原来呀!是浮力的作用,物体上、下面浸没在液体中的深度不同,物体下部受到液体向上的压强较大,压力也较大,可以证明,浮力等于物体所受液体向上、向下的压力之差。例如:石块的重力大于其同体积水的'重量,则下沉到水底。浮木或船体的重力等于其浸入水中部分所排开的水重,所以浮于水面。气球的重量比它同体积空气的重力小,即浮力大于重力,所以会上升。这种浸在水中或空气中,受到水或空气将物体向上托的力叫“浮力”。例如:从井里提一桶水,在未离开水面之前比离开水面之后要轻些,这是因为桶受到水的浮力。不仅是水,例如酒精、煤油或水银等所有的液体,对浸在它里面的物体都有浮力,所有物体都一样。在我的观察、试验和分析过程中,逐渐解释、揭示了物体在水中或沉或浮的奥秘,使我增长了知识,把学到的知识联系实际加以应用,既巩固了学到的知识,又提高了学习的兴趣,还初步学会了科学观察和分析方法。
使我不禁感叹!在我们的生活中有太多太多的科学现象等待着我们去发现、探索!

As is shown above, a leader father is sitting in the chair with a seal grasping in the hand, and a lot of money beside him. He seriously said to his son that there is more to life than just money -it is power. Simple as the picture is, but a profound truth is reveled in the picture.
I surely disagree with father ’s philosophy. As a leader, he shouldn ’t use his power to make money. It is his duty to serve people wholeheartedly, just one person said “with great power comes great responsibility ”. If he stick to his philosophy. I believe that he will spend the rest of his life in prison. What’s worse, he could affect his son ’s philosophy, guiding him in the opposite direction , nothing can be done to reverse the trend itself. The only solution is to change father ’s philosophy. Because of many greedy officials in China, it is time to reverse the trend itself by establishing new policy. As Chinese always has been our confidence that we can change for the better and better.
In my opinion, there is more to to life than just money -it is happiness, nothing is important than happiness. We can live a colorful life in our spare time.
