基础写作：衣食住行的变化与未来

With the science and technology developing fast， life is new every day and the present is quite different from the past. And what will life be like in the future?

Living in houses made of wood or grass in the past， people now live in tall buildings or flats and maybe they will live underwater or in other planets in the future. Riding a horse was common in the past， which was too slow but today most people travel by motorbike， car， train or plane and will travel in spaceships in the future， which will enable them to go anywhere at any time they want.

People used to wear clothes made of silk or cloth by hand， but now the clothes are made of wool， nylon and cotton and we can imagine that in the future people will not have to wash the clothes they wear.

As to reading， people read only scrolls or paper made from bamboo in the past but now we can read not only books but online books while in the future people will read electronic materials or on cellphones. With a very small machine in hand， they can take out whenever they want to read.

We live a happy life now and the future is wonderful. We should value what we have today and work hard for the bright future.

读写任务：面对日新月异的电子产品该如何选择

Varieties of electronic gadgets, without which some of us can’t live, come into being. Despite their conveniences, they bring people much stress, so people have to balance their advantages and disadvantages before buying them.(34 words)

I can’t agree more with the author. With the development of science and technology, more and more fantastic electronic gadgets come into being, which dazzles people. People can’t resist the temptation to buy and update them since these gadgets become outdated too quickly.

I have a lot of favourite electronic gadgets， one of which is a video MP3. As well as carrying my favourite music， a video MP3 player can play up to 150 hours of movies and TV programmes. However， it cost me 2，000 yuan. Besides， the loud volume will damage my hearing if I overuse it.

If I want to buy a necessary electronical gadget， the first factor that should be taken into consideration is whether it’s practical.(120 words)

篇三：科学作文

关于科学精神的小作文

想起小时候，7岁的我是一个特别爱幻想的小女孩，常常躺在床上，望着窗外湛蓝的夜空中，一颗颗像水晶葡萄似的星星，我忍不住伸长手，想抓来一颗尝尝它的滋味。就因为我这种天马行空的想象力，为我亲爱的老妈带来了一连串的“灾难”。

“天哪！”一大早，老妈的惊呼声，把我从美好的梦境中，拉回了现实。我循声而去，只见老妈一脸无奈，嘴里念念有词：“这什么鬼天气,昨天还阳光明媚，晚上就下起倾盆大雨，晾的衣服全湿透啦。可这条裙子和短袖我同学聚会时要穿的呀！这下??唉！”我知道这是老妈最心仪的一套衣裙，爱美的她可是要在同学面前一展风采的呀。看着老妈在一旁唉声叹气，我不禁在心里开始打起了如意算盘，妈妈不是常鼓励我要当一名科学家吗？哈哈，我大显身手的时候到啦！

为了讨好老妈，好不容易等到她出门后，我马不停蹄地开始了我惊人的计划——把裙子和短袖用最快最特殊的方法晒干。我——古雪，当然不走寻常路。可是用什么方法才能成功呢？我托着下巴，像一位资深的科学家一样沉思着。目光四处搜寻，当扫过微波炉时，眼前顿时一亮。想起它能把冰冷的东西变热，是不是也能把湿润的衣物变干呢？我偏着脑袋想了一会儿，最后拍了拍微波炉，一本正经地说道：“老兄，一切都看你的啦！”接着，我便满怀希望地双手捧着裙子毕恭毕敬地送进了它的“嘴”里，我为自己的伟大发明感到无比自豪。 微波炉开始运作起来，我眼前似乎浮现出妈妈表扬我的情景：她满脸惊喜，一个劲儿夸我是个天才呢！“滴滴滴”微波炉给出停止提示音，我满怀希望地打开了微波炉——啊！我的妈呀！眼前的景象让我吓了一大跳。经过微波炉的“煎熬”，原本漂亮的裙子冒着一缕缕青烟，已是千疮百孔，似乎在向我伤心

拿着破烂的裙子，我好不心疼，我又内疚，又害怕，此时此刻已经不敢想象当妈妈见到这条裙子时的表情。不行！我不能在这儿坐以待毙，我得振作起来，不是还有一件短袖吗，这下只许成功，不许失败！

我努力地寻思着，“卡嚓”脑袋里灵光一闪，一个词语蹦了出/来——吹风机。它可是能把湿发吹干，那么把湿衣吹干也是小菜一碟吧！可先前的教训提醒了我。没有经过实验可不能轻易下手呀，我迅速找来一块湿布，用吹风机“扫瞄”起来，一会儿，原来湿漉漉的布变干了，并且完好无损。我一阵狂喜，拿起短袖小心翼翼地铺在桌上，像战士握着冲锋枪似的，沉着、冷静、勇敢地开始正式实验，生怕有一点闪失。吹风机欢快的吐着热气，数分钟后衣服全变干啦，那种成就感刹时来临，我开心地拿着衣服蹦起八丈高。

现在，每当我回想起那次尝试，就忍不住巴哈哈大笑。不过，从中我领悟到科学的尝试虽然离不开天马行空的想象，但也有可能付出代价哦！

科学实验

今天我做了一个挺有意思的实验，发现了一个非常有趣的现象：蚂蚁怕樟脑球。

我翻箱倒柜地找出一颗樟脑球，在墙角找到了一群蚂蚁，我选中一只最大的蚂蚁，实验就可以进行了。

我把蚂蚁放在水泥地上，用樟脑球在它前面画了一条线，只见蚂蚁慢慢地向前爬行，一对触角不停地摆动着，蚂蚁走了几步，刚好碰到线上，可不知为什么，它就像触了电似的向后退，不走了。我把蚂蚁向前推了一下，正好推到线上，它连忙一个冲刺冲过了线。

于是，我又用樟脑球在它前面画了一条线，这回蚂蚁走路变得小心翼翼了，它走两步就停了下来，当走到线那儿时，又向后退了几步，就向旁边爬去了，我用手指挡住它的去路，没办法，它只好向另一侧爬去了，我又用手指挡住，它还是不向前走，我只好又把蚂蚁推到线上，它像疯了似的向后退了又向前进，折腾了半天，终于冲过了“防线”。

我又在小蚂蚁周围画了一个圆，只见蚂蚁东碰西撞沿着这个圆走，想找出口，但一直找不到，便放弃了，它爬到圆中心，呼吸新鲜空气，我趁机又画了一个小一点的圆，蚂蚁迅速爬到了圆中心，我又画了一个更小的圆，蚂蚁闻到樟脑球的气味，神魂颠倒起来，它像无头苍蝇似的乱撞，却始终不肯走出包围圈，可这个圈离圈外总共才只有五厘米一段距离，如果它能向外冲一冲，就有生存的可能，如果它老呆在圈内，那只有坐以待毙了。

我身边的科学作文

奶奶终于来了我家，我坐在沙发上看电视。忽然，我听见奶奶喃喃地说：“嗯，肚子有点儿饿了，热几分钟吧！”于是，奶奶拿出装在金属碗里的红烧肉，说：“在微波炉热几分钟吧！”奶奶刚刚想放进微波炉。妈妈看见了，连忙跑到奶奶身边，一把抢过奶奶手中的金属碗，说：“妈妈，您知道吗？金属碗是不可以放在微波炉里打的，不然，有可能会爆炸的......”这句话被我听到了，心想：还好，还好！平时妈妈不在的时候，没有乱用微波炉打东西，不然可惨？我就早变成一只“小乌鸡”了！我迅速跑到妈妈旁边，小声地问：“为什么金属制品放到微波炉里打，会爆炸呢？”“这是因为——”妈妈一本正经的说，“在微波炉里放金属制品，尤其是比较大的金属制品，容易造成微波发生反射而损失磁控管。磁控管是微波炉内发射微波的大功率器件，就很容易爆炸了......”“哦......”我点点头，说。

“同学们，你们知道了吗？金属制品是不可以放进微波炉里加热的哦！可要记住啦~”

剥鸡蛋皮

早晨第一缕温暖的阳光射入我的房间。随着一阵闹钟铃声和妈妈的唠叨声，我终于从床上爬起来。穿好衣服后，我一面打着哈欠一面走进洗手间。一阵忙碌后，我又来到饭桌前。

“哇！”我顿时提起了精神。原来桌上摆着的锅里有刚煮熟的鸡蛋。哈哈!它可是我的最爱！我连忙拿起一个，哎呀！好烫啊！我使劲地把鸡蛋往桌上一磕，嘴里不停地吹气，左手甩动着，右手轻轻剥开，可蛋壳似乎在和我作对，紧紧粘在蛋白上，怎么也剥不掉，还把一块块蛋白给剥了下来。 妈妈从厨房里走出来，见我这副狼狈样，端起锅说：“你等等！”

“妈，你要干什么呀？”我像丈二和尚摸不着头脑，一脸疑惑地望着妈妈。 只见妈妈把锅端到水池，打开水龙头，给鸡蛋洗了个“清凉澡”。她走出来，递了一个鸡蛋给我，我接过鸡蛋有点迟疑，只得轻轻敲开，没想到两三下接剥开了，里面的蛋白光滑又平整。咬一口，真香！

妈妈在一旁笑着说：“刚煮熟的鸡蛋温度高，在膨胀，用冷水一冲，蛋遇冷就收缩，这样一来，蛋白和蛋壳分开了，鸡蛋也就容易剥开了！” 噢！我恍然大悟，原来是热胀冷缩的道理呀！

生活处处藏着科学，只要我们认真去发现，去观察，不仅给我们的生活带来方便，还能增长不少知识呢！
