I know you are fond of swimming. A river lies not far away from my home. We can go swimming there. I think it would be very pleasant and refreshing to swim in such hot summer days. In every big room of my home there is an air-conditioner. We can watch TV, play CDs or read books very comfortably at home.
A mountain about two miles away from here is beautiful and it is worth touring. We can go there on foot. When we climb to the top of the mountain, we can have a wonderful bird-eye view of the whole village. Just phone me before you set off. There is no need for you to take anything. Ill prepare everything for you.
I am looking forward to seeing you soon.

英语作文我同学的周末【三】
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！
