生活的变化的英语汇编20篇

今天为大家来介绍一些化学变化。

（一）

前几周我们班进行了一次白糖加热的实验，现在我来帮同学们回忆一下白糖加热这个实验吧。

做这个实验得先准备好材料。白糖加热少不了的就肯定是白糖啦，有了白糖，怎么加热呢？我们可以用身边的蜡烛来担当火源。哦，对了，还要准备好一只长柄汤匙，为的是在加热过程中盛白糖。不过，要是烫到手怎么办呢，那就再准备一副手套吧。

材料都准备好了，该做实验了。先把手套戴好，再拿着汤匙，要拿在汤匙较上面的部分上，因为这样就不容易被蜡烛燃烧起的火烫着。然后再把白糖倒在汤匙上，至于白糖到多少，没有规定，我建议倒半勺。我认为倒少了不容易观察记录，而到满满一勺的话，也许在加热的过程中会溢出来。现在就把蜡烛放在桌子上，桌上最好铺上报纸或抹布，因为同学们都知道蜡烛燃烧后蜡油会滴下来，所以先铺上一些东西比较好。这是，再把蜡烛点燃，把汤匙放在蜡烛上方，进行加热。然后我们就要做观察记录了。

在加热白糖的过程中，我们看到白糖先是由固体变成液体，这样的现象是属于物理变化的，然后继续加热白糖，糖的颜色逐渐变成红褐色，并且如果凑近一点去闻白糖，还可以闻到一股淡淡的香味，这种变化是属于化学变化的。那么我们再来回顾一下还没有加热过的白糖是什么样，首先它肯定是固体，如果我们用放大镜来看，还能看到它是有规则图形的物质，所以它也是晶体，其次，白糖肯定是白色的。而加热过后，白糖不仅变了色，气味儿也有了改变。加热过程中白糖还在冒泡，这充分的说明了白糖加热的过程中，不仅产生了物理变化，还产生了化学变化。

白糖变化奇妙有趣，生活中其实还有很多化学变化，比如下面为你介绍的小苏打的化学变化。

（二）

其实需要的材料并不多，既然是小苏打的化学变化那么小苏打是肯定少不了的；再来就是白醋一瓶啦，还需要一片玻璃，这是为什么呢？原来，在实验过程中会产生许多的气泡，需要一块玻璃来遮挡，把这些气体“困”在反应容器中；除此之外，自然少不了杯子。接下来为大家有请我们俩的好伙伴——杯子小姐来为大家介绍这个实验吧！

大家好，我是杯子小姐，接下我将带领大家进行一次小苏打化学之旅。首先放大约 2克 的小苏打，可千万别太多，不然待会的实验可能会出现小意外哦！接下来是关键，一般来说白醋的瓶盖都差不多大小，将白醋倒满在瓶盖里，然后小心翼翼地把白醋倒入我的“肚子”里，之后就马上盖上先前准备的那块玻璃，你会发现小苏打与白醋产生了剧烈地变化，你可以明显观察到我的“肚子”里正在发生变化，有不明气泡在不停地往上涌，一层雾铺在玻璃上。你将双手放在我的身上，啊呀！不错，是凉凉的，这种感觉很奇妙吧！将小苏打与白醋混合产生的这种新物质到底是什么呢？这种气体形态的新物质到底有什么特点呢？同学们紧接着进行了下一个实验。我看尽大家点燃了一根火柴，他们将燃烧的火柴放进我的“肚子”里了，可是不一会儿这种不明气体就将燃烧着的火柴熄灭了，问题接二连三地来了，同学们的问题也随之增加，一种求知的欲望覆盖在同学们的心上，可是有力的证据显然不足，终于我们的刘老师公布了答案，这种气体就是二氧化碳，从实验中大家得知二氧化碳是一种不支持燃烧的气体，能够通过实验来验证真是太有意思了！

同学们，这个实验可真是有意思，不仅观察到了小苏打与白醋混合产生的变化，还了解到了二氧化碳的一种特性。时间不早了，杯子小姐要跟你说再见了！我们有机会再见。

其实这些化学变化只是科学世界里的一小部分，神秘的科学世界还有许多未解之谜等待我们去探索。

生活中充满着变化，正是这个无时无刻不在变化着的世界，为世人演绎着精彩的乐章。

我是千千万万独生子女中的一员，或许会因为是家中唯一的宝贝而更受父母宠爱，或许会从家人亲戚那里获得更多的关心与照顾，但是独生子女特有的孤独感却是这些爱所无法代替的。从小就缺少兄弟姐妹陪伴的我习惯了爸爸妈妈出门上班后要自己按时起床，一个人坐在小椅子上抱着布娃娃给它讲外婆告诉我的故事，习惯了从冰箱拿出妈妈提前做好的饭菜用微波炉热好后作为午餐，习惯了一个人趴在窗台旁发呆，心里默默念叨着，盼望着爸爸妈妈能快点下班回来陪我……正是这样，我从小就安静而内向，我时常幻想着这样枯燥的日子能发生些改变，而我也不再感到如此孤独，直到小学一个暑假，一只咖啡色卷毛的泰迪狗闯进了我原本单调的生活。

那天晚上，妈妈刚下班就打了个电话告诉我要带来一个小伙伴，我欣喜若狂地迎接这位特殊的“朋友”，我隐约意识到我的生活将因此发生改变。“一身毛茸茸的蓬松到让人总想上去抱抱，一双无时无刻不透露出天真无辜的大眼睛，同镶嵌着的两颗黑色玻璃珠一般，总是湿漉漉的小鼻子下是一张看似总在撇嘴笑着的嘴巴，而粉嘟嘟的舌头伸出了一大截。”就是这样一只可爱的小家伙，陪着我度过了那些本该独自在家的日子。”又是爸妈都不在家的一天，不过我的失落感并没有持续多久，就被眼前这个活蹦乱跳的小家伙感染了，它一个劲的往我身上蹭，好像在说：“快抱抱我，我可比你的布娃娃有意思多了。”

我一把抱起她，边帮它抓抓痒，边笑话它那滑稽的摸样。紧接着，她开始耐着性子听我讲最拿手的童话故事;过会儿又静静地趴在钢琴踏板旁仰着头陪我练琴，就连午饭的时侯，它都像模像样地坐在小椅子上看着我吃，偶尔赏它两片小肉就可以让它高兴半晌……她从不抱怨什么，只是乖乖的作为一个朋友来陪伴我。悠悠的贴心与懂事着实令我惊奇，如果要让我找出它犯过的错误，那可真算是件难事，因为它是我见过最棒的朋友之一。

悠悠，你知道吗，我多么感谢有你的陪伴，你的来到给我的生活带来了欢笑，使我不再感到孤独，使我变得像你一样开朗活泼，无忧无虑，我真为有你这样的朋友而感到荣幸，是你，让我的生活变得更加精彩。

I imagine a lot about lives in the future。I think two words can summarize my imagination。The first word is fast。In the future，we will have more quickly transportation means。

Now matter how far we go，it takes only a short time。With the development of science and technology，we can travel to the moon，Mars or somewhere outer space。People may can live in other planets。The second word is convenient。

Because of the fast development of our society，many work can be done by computers or even robots。

Lots of things are fully automated。Humans just need to give some simple instructions to complete complecated tasks。

我对未来生活充满了想象。我认为可以用两个词来概括我的想象。第一个词是快速。将来，我们会拥有更快的交通方式。不管我们去得多远，它总能在短时间内把我们带到目的地。

随着科学技术的发展，我们可以到月球，火星或者其他外太空旅游。人们也许可以在其他星球居住。第二个词是便利。

由于社会的快速发展，很多工作可以用电脑或者机器人来完成。很多东西都是全自动的。人们只需要提供一些简单的指令来完成复杂的任务。

I am going to shool from Monday to Friday,and every day in school I am very busy.In the morning,I have four lessons,and in the afternoon I have three lessons.Of course I take two hours to go home for lunch.And we begin classes at 2:30,the school is over at 4:55.

After school,sometimes I’ll stay in the classroom.But sometimes I play games with my friends when I go home after school.I think my school life is busy but happy.

The word "low carbon" has become the pronoun of 21st century, low carbon is also because now people realize the importance of protecting the environment, to create a word. So I decided to, in the future life, I also want to "low carbon" everywhere, protect our survival homeland.

Everything from the beginning of the trip, I go out less as far as possible to get a taxi, short distance of walking, long distance sit bus. I found that, after a period of time, I will save money, and exercise the body, is the best of both worlds.

Then, we should start from the water. I try to use the laundry water to clean the toilet, mop the floor... Every time to drink water, I will pick up as much as they remember to drink water, not pick up more, save water resources. Slowly, I found that mop and clean, even I can do.

In the end, is the power saving. Brightly lit at night, our family, each room the lights are on, sometimes, no one in front of the TV, TV is still open, waste a lot of electricity. I told mom and dad, the door after you leave the room. Dont watch TV, remember to turn off the television, and less use the computer. In the daytime, can not turn on the light, dont turn on the light. Our family all do that, I believe that our electricity will be a lot less. Two months later, the mother to go for electricity time-consuming, found many degrees less electricity!

I learned from the Internet, in Beijing, people in order to make cars less discharge exhaust, with single and double car that runs on different dates. To develop car free day, also hope you can low carbon life, the protection and preservation of our home!

低碳”这个词已经成为21世纪的代名词，低碳也是因为现在的人们终于认识到保护环境的重要性，才创造出的这个词。所以我决定，在以后的生活中，我也要处处“低碳”，保护我们生存的家园。

一切从出行开始，我出门尽量少坐出租车，距离短的就步行，距离长的就坐公交车。我发现，一段时间后，我既节省了路费，又锻炼了身体，真可谓两全其美。

接着，就要从节水做起了。我尽量用洗衣水来清洁马桶、拖地……每次喝水，我会记着要喝多少就接多少水，绝不多接，节约饮用水资源。慢慢的，我发现，地拖得越来越干净，连我都能照的出来了。

最后，就是节电了。一到晚上，我们家就灯火通明，每个房间的灯都开着，有时，电视机前没有人，电视依旧开着，浪费了不少电。我告诉爸爸妈妈，离开房间后要随手关灯。不看电视时，记得将电视关闭，并且少用电脑。在白天，能不开灯，就不要开灯。我们一家人都那么做，我相信，我们家的电费一定会少不少的。两个月后，妈妈再去交电费时，发现少了好几度电呢!

我从网上了解到：在北京，人们为了让汽车少排出尾气，有了单双号汽车在不同日期行驶。制订了无车日，也是希望大家可以低碳生活，保护我们赖以生存的家园!

Today is the last day of the winter vacation, I think it should be a review of the harvest of this winter vacation.

Shortly after the winter vacation, my brothers are coming back from the field.

[关于生活习惯英语作文

When I go to high school, our school has the rule to ask students to live

in the dormitory. Most students live with their parents before, so we all feel

excited and afraid of the group life. Luckily, I have three nice roommates. Soon

we become close friends. Living with others, we learn to do the house work, such

as everyone needs take turn to clean the floor, when we have something good to

eat, we will share with each other. The group life makes us have less private

space, but we enjoy the moment when we have the little talk before sleep, the

secrets that we dont want our parents know can talk to these girls. Whats

more, I become much independent. I learn to take care of myself and have really

grown up.

I was happy this summer holiday! Do you know why? Because I had enjoyed a good summer holiday! In the morning, sometimes I went toYueXiuParkto play badminton with my families or friends. We always went to McDonalds to have lunch after we finish the game. My sister and me like swimming, so in the afternoon, we went to swimming with our father. It was so cool! It feels so great to swim in such hot summer days.

这个暑假我很开心。你知道为什么吗?因为我度过了一个愉快的暑假!早上，有时候我和家人或者朋友到月秀公园打羽毛球。游戏结束后，我们经常去麦当劳吃午餐。我姐姐和我都喜欢游泳，因此，下午我们通常和爸爸去游泳。游泳是如此凉快。在这么炎热的夏天游泳感觉是那么的棒。

生活中变化的例子太多了，举不胜举。人的品格会变化；四季会变化；天气会变化，时阴时雨；人的长相会随着年龄的增长在变化；地位也会变化，你可能会从天上落到地下；心情也会变化，表扬一个人，他一定会高兴，相反，如果他受批评，一定会不高兴，所以心情也在变化着；身体也在变化着，你上午还好好的，到了下午便病倒了，这也是变化；名誉也会变化，现在你如天上的太阳，可一百年后、一千年后你可能是受人唾弃的一个对象呢，别说我胡说，秦桧不就是这样的人吗？最切合实际的变化，那便是时间了。借用朱自清的一句话吧“天黑时，我躺在床上，他便伶伶俐俐的从我身上跨过，从我脚边飞去了。等我睁开眼和太阳再见，这算又溜走了一日”。以上例子表明了一个问题：生活之中无不体现着变化。

变化，是时间进军的步伐；变化，也是一件成就，只为它改变了原来的，变成了现在的。每个人干一件事都应有变化。

让我说说人类的成就造成的变化吧：以前住的是小平房，只有一层；现在一幢幢楼房拔地而起，高达二三十层；这不是变化吗？以前出门的交通工具是马车，速度慢；现在大部分人家都有汽车，很快了。不说小的，如果你从西藏要去吉林，你坐马车要走上几年呢！变成飞机，几小时便到了。这不是变化吗？以上的成就表现出一个标题：人类的成就也是变化。

发现变化，是看你有没有一双善于发现的眼睛，并不是凭空出现的。正是因为时代的变化，所以生活为了适应时代才有如此多的变化。我相信：再过一百年，变化一定更多。记住，变化始终在继续着。

living in a city has both advantages and disadvantages. it is often easier to find work. there are always many choices of public transport. besides, there are a lot of interesting things to do and places to see. you can eat in good restaurants, visit museums, go to cinemas and go to parks whenever you want to relax. however, living in a city is often very expensive. you must find a well-paid job, otherwise, you will not be able to afford the things you will do. whats more, the city is always crowded, noisy and dirty. it is very difficult to find a good place where people can enjoy peace and fresh air as in the countryside.

Today, after school, my friends asked me to have dinner with them, I felt so happy and went the restaurant with them. Then I found they wanted to eat buffet, I was so happy, because I always wanted to have buffet, I could eat a lot of food.

As we paid the money more than we usually spent, so all of us wanted to eat as more as possible, even though we were full enough, we still tried to eat. I would go the wash room many times, so that I could continue to eat. I found eating the buffet should be a happy thing for me, but now it seemed to be a kind of torture, I always told myself to eat more than I could bear, my stomach hurt.

The experience to eat buffet lets me realize that I should enjoy the food instead of eat more than I could bear.

"Low carbon" start small, since the sixth grade, as long as I dont save, mom and dad will speak of the words in my ear. To this end, I decided that I really want to be a low-carbon life. Remember once, mom after using the mask, just ready to throw away, just let me see, I hurriedly shouts to prevent a mother: "mom, cant throw away!" Mother heard after, immediately stop. I ran over and took the mother in the hands of the mask. Then said to his mother: "mom you have finished using the mask cant throw, said on television the mask after use can wipe furniture, not only a bright shine, and its fragrance.

"After listening to his mother, smiled and patted my head say:" my daughter really understand low carbon life. "I cant agree in front of dad, in a few days ago, because our wardrobe very damp, mom and dad are there, then I thought of my grandma often use newspaper mat in the wardrobe, she told the newspaper can be moistureproof, still can absorb peculiar smell, so I went to the newspaper, but used the newspaper all let me away, now also really didnt have the newspaper in the home, the somebody else all say" books to time square hate less "but I want to say today" newspaper when hate nothing ". Well, by the way, today I thought I saw daddy came home from work with a newspaper, I hurriedly found the father, "dad you back a newspaper today? "Dad puzzled nodded, I cant wait to say:" quick contribution out, I have an idea. "

When dad see me the paper pad in the wardrobe, harm my dad cant find newspapers and buy one. Now, I walk to school every day, no longer let father motorcycle send me; Every time I go shopping bring your own bag... I want to live a low-carbon life. Low carbon starts from me, lets construction of a new civilization, happiness, charm, donggang.

“低碳从小做起”，自从上六年级以来，只要我不节约，爸爸妈妈就会在我耳边说起这句话。 为此，我决定真的要做个低碳生活的执行者。 记得有一次，妈妈用完面膜之后，刚准备要扔掉，恰巧让我看到了，我连忙大喊一声阻止妈妈：“妈妈，不能扔掉!”妈妈听见了之后，立即停下。我飞快跑过去，夺下了妈妈手中的面膜。然后对妈妈说：“妈妈你用完的面膜不能扔，电视上说面膜用完之后可以擦家具，不仅擦得亮，而且还有香味。

”妈妈听了后，微笑着拍拍我头的说：“我女儿真的懂得低碳生活了。” 在爸爸面前我也不能服输，就在前几天，因为我们家的衣柜很潮湿，爸爸和妈妈都无计可施，这时我想到了奶奶常常用报纸垫在衣柜里，她说过报纸可以防潮，还可以吸收异味，于是我就去找报纸，但是以前用过的报纸都让我扔掉了，现在家里还真的没有报纸，人家都说“书到用时方恨少”今天我却想说“报纸用时方恨无”。嗯，对了，今天我好像看见爸爸下班时拿回来了一张报纸，我连忙找到了爸爸：“爸爸你今天是不是拿回来一张报纸?”爸爸疑惑不解的点点头，我迫不及待的说：“快贡献出来，我有办法了。”

当爸爸看我把报纸垫在衣柜里时，害的我爸爸找不到报纸又买啦一张。 现在，每天上学我都步行，再也不让爸爸摩托车送我;我每次逛街都自备口袋……我要过真正的低碳生活。 低碳从我做起，让我们一起来建设文明、幸福、魅力、新东港吧。

The world is changing all the time, and my hometown is no exception. In recent years, my new eyes have witnessed the welcome changes in my hometown.

The mountain in the hometown changed, the former bald "steamed bread", now green oil; The water in my hometown has changed. Once full of mud and mud, the water is now crystal clear. The road in my hometown has changed. Once the muddy dirt road, now not only became the spacious asphalt road, but also repaired the traffic light; The house in my hometown has changed, and  bungalow, formerly short and small, is now a spectacular high-rise building. The transportation tool in my hometown has changed. Once upon a time, it was the goal of the people to have a bicycle, and now the streets are almost all beautiful cars. The clothes of the family changed, and there was a patch on the clothes of the old people. In the past, there was another saying, "three years, three years, three years of sewing." And now, peoples clothes are colorful, fashionable, there are suspenders, suits, skirts, dresses, and so on, very beautiful...

My hometown is changing day by day.

Home is changing little by little.

I opened my eyes wide, observed carefully, searched carefully, and carefully found... I wish I could change all the changes of the mountains and rivers of my hometown, and put them all into my mind and become a part of my beautiful memory.

Once upon a time, there was nothing at the edge of the Yellow River.

Now, the yellow side construction is very good, there are a lot of colorful lights on the Yellow River, there are a lot of lights on the bridge, the bridge is also full of colored lights, some of the bridge also has spotlights!

The sculpture on the edge of the Yellow River is also beautiful, with the Yellow River mother, the tang priest in the journey to the west, and so on, the statues are all vivid, as if they were real.

The most beautiful is the music fountain. The music fountain has a acoustics next to it. It has a wonderful music. The fountain will go up and down with the music rhythm. The pool also has colorful lights, very beautiful.

When the foreigner came to lanzhou, they said that the Yellow River was comparable to the bund in Shanghai.

Ah! I am pleasantly surprised to find that my hometown is undergoing rapid changes, and our motherland is also undergoing earth-shaking changes! The change of hometown is a microcosm of the prosperity of our motherland!

I love my lovely hometown!

As is known to all, the survival environment, is the human is very concerned about a word. Why do humans are very concerned about it? This is because the living environment, to human, to animals, all living things upon earth has great significance. The lack of a species, what cant seem to affect in humans, but in fact, the lack of a species, will produce great threat to all life on earth.

Take shrimp, for instance, imagine that. If the earth did not have the sharks... What? I dont think should be like this: the shrimp, fish will starve to death, (though in fish recipes and other food, dried shrimp is a major food fish), and the big fish, also didnt eat for the extinction of small fish, also be starved to death...

Thus, if less a creature in nature (including animals, plants, microorganisms, etc.), would be terrible, even have a high IQ of human mind, also be restrained food chain, so human attaches great importance to this problem.

So how can I have a good living environment? This is very simple, as long as everyone can "low-carbon life"!

But the biggest problem is how a "low-carbon life", the so-called "low carbon life", is refers to the life work and rest when try your best to reduce the energy consumption, thereby reducing carbon, especially carbon dioxide emissions, thus reducing the pollution of the atmosphere, slow ecological deteriorating, mainly from power saving throttle and recovery of three links to change life details.

Should do low carbon life, electricity from solar terms and recovery of three links to change life details.

众所周知，生存环境，是人类非常关注的一个词。为什么人类非常关注它呢?这是因为生存环境，对人类，对动物，对地球上所有生物都有着极大的意义。缺少一个物种，对人类似乎造不成什么影响，可事实上，缺少一个物种，就会对地球上所有生物产生极大的威胁。

就拿虾米来说吧，设想一下。如果地球上没有了鲨鱼。。。。。。那会怎样呢?我想应该是这样：没了虾米，小鱼就会活活饿死，(虽然在小鱼食谱还有其他的食物，可是虾米是小鱼主要的食物)，而大鱼呢，也因为小鱼的灭绝而没有吃的，同样被饿死。。。。。。

由此可见，大自然中若少了一种生物(包括动物·植物·微生物等)，将多么可怕啊，就连有高智商头脑的人类，也要被食物链克制着，所以，人类非常重视这个问题。

那么怎么才能拥有一个良好的生存环境呢?这非常简单，只要人人都能‘低碳生活’就行啦!

可最大的问题就是怎么个‘低碳生活’，所谓的“低碳生活”，就是指‘生活作息时所耗用的能量要尽力减少，从而减低碳，特别是二氧化碳的排放量，从而减少对大气的污染，减缓生态恶化，主要是从节电节气和回收三个环节来改变生活细节。 ’

做到低碳生活，应该从节电节气和回收三个环节来改变生活细节。

It has been two years since I first got to university. Some of my

classmates say that the college life is boring, because they have plenty of time

but do not know what to do. However, from my point of view, the campus life in

college is interesting and colorful as long as you make it meaningful.

In the first semester in college, I didnt relax and I still worked hard as

I was in the senior school. I usually spent two hours in study at night and I

went to the classroom forautonomous learning.But the difference is that I have

many extracurricular activities. For example, I went to the English Corner

regularly on Tuesday night, in which I could practice my spoken English and make

friends with common interests.

Besides, I join the Student Union of my department. In the Student Union, I

have a group of workmates who work hard together and support to each other.

Actually, it looks like a big, warm family that we can share our lives together.

During various activities, I realize the importance of team spirit that helps us

go further.

Finally, college is great stage to improve a student and show ones

abilities. In college, I know more about our society and get more channels to

explore the outside world. I realize that I am not only a student but also an

adult who is preparing to step into the society.

In short, I cherish my life in college campus and I will try hard to make

it colorful as well as meaningful.

Nowadays ,many people are talking about low carbon living. I think each and every one of us is responsible for the greenhouse gases we emit in our daily actions and choices. Therefore, combating climate change is going to take the combined efforts of everyone on the planet.

2010 World Expo was held in Shanghai. Shanghai Expo theme is "Better City, Better Life." As a student, we should do something about environmental protection. For example, plant trees, save water and less your car.
