首先我要去新华书店买书,我已经是那里的常客了。什么类型的书我都爱看,只要有趣味的书我就会废寝忘食。这个周末我决定去买高尔基自传体三部曲之一的《童年》,另外两本《在人间》和《我的大学》,等我看完之后再逐一将它们收归我的囊中,嘻嘻!
如果不去买书的话我就去市民广场溜旱冰。那地方宽阔平整,绿树成荫,空气清新,我可以在那样优美的环境里尽情的溜,而且那里教溜冰的'老师已经认识我这个热爱溜旱冰的小朋友了,他们经常会给我一些好的建议,对我学习花样溜冰很有帮助。我已经开始想像,我穿上溜冰鞋,戴上头盔、护膝、护肘、手套、臀垫、护腕,哗真是全身披甲上阵,先是来个单足蹬冰,双足向前滑行,完了再来个单足向前滑行,然后是双足向前弧线滑行、前交叉步滑行、向后双足滑行……哦!我已是迫不及待了,真想马上就开始我的“冰上之旅”啊!
再或者我去我朋友家玩,我们一起玩孔明锁。孔明锁,也叫八卦锁,相传由三国时期的孔明发明而得名。这种三维的拼插玩具,外观看是严丝合缝的十字立方体,动动脑筋可拆解,但想装上可不是那么容易的。可因为它有一定的难度,所以我们才喜欢玩。哦!孔明锁,此刻开始我想念你了!

妈妈说就我们两个人,炒一盘马铃薯就可以了。于是,在妈妈的指导下,我迅速刨了一个大的马铃薯,虽然刨的皮不是很干净,但妈妈说已经很好了,洗干净就行了。紧接着,我要将马铃薯切成细丝,“咣,咣,咣……”一口气切完了,天哪,这哪里丝,成了马铃薯条了,妈妈看着我的战果,笑了。“挺不错的,第一次能切成这样,很好啦!”正在这时,弟弟拉便便了,裤子也弄脏了,一点征兆都没有。我只好放下手中的活,去帮妈妈了。十几分钟后,等我再回到厨房,惊讶地发现黄色的马铃薯条已经变成了红色,过了一会,甚至变成了褐色,这让我大吃一惊。
我跑去问妈妈,“妈妈,马铃薯怎么变色了呀?”
妈妈看我一副好学的模样,语重心长地说:“因为马铃薯里含有淀粉,淀粉如果接触到空气就会氧化就会变色。而且当马铃薯削皮后,植物细胞中的酚类物质便在酚酶的作用下,与空气中的氧化合,产生大量的醌类物质。新生的醌类物质能使植物细胞迅速的`变成褐色,这种变化称为食物的酶促褐变。”
哦,原来是这么一回事啊!
妈妈又给我讲了好多关于马铃薯的知识,让我受益匪浅。我只知道,马铃薯就是我们常说的“土豆”,其实它还有很多亲昵的称呼:法国人称它为“地下苹果”;德国人称它为“地梨”;俄罗斯人称它为“第二面包”。在我国,马铃薯也有不少美称;东北人叫它“土豆”,西北人叫它“洋芋”,华北地区叫它“山药蛋”,江浙一带叫它“洋番芋”。原来生活中有这么多的科学,我立马来了兴趣,也不感觉饿了,就决定做一个实验,看看如何才能使土豆不变色。实验开始了,我先把一个土豆切成4份,一份用柠檬水泡着,一份用盐水泡着,有一份用糖水泡着,还有一份用冷水泡着,过20分钟,看看会发生什么变化。20分钟过去了,我一看,呀!在柠檬水、盐水、糖水、冷水里泡着的马铃薯都没有变色。看来,以后切开马铃薯都要放进水里泡着,不管什么水都可以,这样就可以避免马铃薯变色。
最后,妈妈趁着弟弟睡着后匆匆炒完菜,我们俩才算吃了顿午饭,吃完饭已经快两点了。
经过这一次体验生活,我明白了一个道理:生活中处处有科学,我们应该多观察、多发现、多研究,让我们和科学一起成长!
Last Sunday we went to the countryside. There was golden wheat all over the fields/The fields were covered with golden wheat. Large and colourful apples and pears were hanging on the trees. We could see some peasants were busy getting in the crops in the fields,and others were picking fruits under the trees. All the baskets were full of lovely fruits. It was also the fruit of the peasants'labour."No pains,no gains."What a magnificent/beautiful picture(it was!It seemed as if we were wandering in a splendid/wonderful world.
I love autumn. I love the harvest time.
It was a sunny day. We decided to have a picnic outside the city. In the morning, we took an early bus to Nanhui. It was quite a colorful world. there were GREen trees, orange leaves,red peach blossoms.
At noon, we reached the place, we sat by the river bank and took out a lot of things, such as bread, orange juice, apples, cakes, eggs and so on.But all of a sudden, it began to rain. Unluckily there was no shelter nearby. We had to take a bus to go back home in a hurry.
What an unforgettable picnic it was!
