Today is my shopping day.I wanted to buy some delicious food.there were many kinds of food.I wanted to eat more vegetables and more fruits.I wanted to eat apples in order to lose weight.I liked eating bananas,straw berries,pears and watermelons,I wanted to buy some books,I thought they can help me study not long after my holidays,I wanted to buy a pair of golves for myself because my golves were lost.And I bought some CDs.

Now more and more bike sharing brands have emerged, such as ofo, Mobai,

Wukong bicycle, Xiaoming bicycle and so on, which are convenient for our travel.

As long as we download a software, we can pay some money to rent a car. However,

since I saw some phenomena, I have asked myself, "is bike sharing convenient or

harmful?"

Bike sharing is very popular recently. Ofo software or other sharing

software can be found in almost all mobile phones of "mobile phone family".

However, once my mother came home full of anger, scared me to speak. I shuddered

and asked, "Mom, what makes you so angry?" She put the bag in her hand on the

table and made a loud "pa -". "Your sister helped me install an ofo software in

my mobile phone. I wanted to make it easy to ride back with good medicine, but

today I rented a" broken car "!" I was puzzled: "ofo still has a broken car

"That is, otherwise, how could my feet be bruised?" She moved her foot to me,

and a black wheel mark was still visible. "When I was riding, the chain was

loose. If it wasnt for my fast braking speed, I would have fallen off!" Since

then, Ive been less fond of bike sharing.

Once I went to a make-up class, I saw two workers sitting on a Mobi

bicycle, shaking and laughing. Dad was very indignant and said: "this kind of

person really does not speak of public morality! Make fun of the public car I

know that they wont do this with their cars. My heart is like bleeding. Why,

they want to "bully" bike sharing.

Once I went out to play. The weather was very good and I was in a good

mood. I look up to the side, really do not see do not know, a look scared. A man

secretly removed the wheel of an ofo and replaced it with a bad one on his own.

After that, he rode off on the ofo wheel. Only the ofo little yellow car was

lying alone, and the wheels were not installed properly. It is like a injured

little girl, whose legs have been taken away, like vanca, can not endure the

sunshine of life. At that time, my tears began to drop. Is bike sharing "shared"

or "exclusive"?

There have been news reports that a boy under 12 years old riding a shared

bicycle was run over by a car and killed. At that time, the boys mother shared

the companys money to compensate for her sons death. Its clearly her sons fault.

He didnt ride a bike before he was 12 years old. I didnt say he deserved it. But

the fact is better than eloquence. The death of her son is not the

responsibility of the sharing company, but his own fault!

I once saw a young man riding ofo without scanning the code. A middle-aged

man pushed ofo into his home. Have you ever seen someone use Mobi without

decoding as fitness equipment? The sound of chain jingling is like a demon with

a chain in his hand crawling out of hell. Thats selfish!

Someone took an image that put the broken ofo and Moby together to fill a

small parking lot. After riding shared bicycles, people park them on the side of

the road at will. As long as a passer-by gently knocks down a car, it will fall

down like a domino.

Have you ever thought that sharing resources is closely related to each of

us, but all the harm they bring is due to selfishness. Bike sharing is just one

example. Ive seen shared bookstores where people leave books on their desks

after reading, so that they cant go home. "Convenience to others, convenience to

oneself." As long as we are convenient for others, we will also benefit

ourselves.

生活里的很多东西，慢慢地随时间的流逝都渐渐变质了，太多的太多你已经分不清楚真假的界限。

以前总是说起别人的虚伪和厌恶，其实想想吧，自己又何尝不是那样的人呢?就比如我也对身边的朋友说过谎，不管是出于怎样的理由，那也是不能否认的事实，有时候真相才是最残忍的伤害，为了自尊不能也不没有勇气去揭开疼痛的伤疤。当你能站在别人的角度去理解，就会明白有的事情就是哑巴吃黄莲—有苦难言!有些人在我们的眼里称作为“小人或者卑鄙……”，只是因为他(她)的行为举止让我们觉的不能接受，反过来去思考一下，当一个人有更好的选择的余地，谁也不愿意去做所谓卑鄙的事情，记得一篇武侠小说里有句话很有味道：“一个人要是还有别的路可以走，谁也不会拿绳子勒自己的脖子。”简简单单的言语，实实在在的说出了不得已的无奈，不然可能也就没有"破釜沉舟"之说。

事事皆学问，生活就是一部丰富的人生书籍，是你永远也读不完的经典哲理与故事，经历是给你最好的赠品，让你体味了百态人生，所以万事如意也好，大灾小难也好，一切都要保持良好的心态去面对。我曾经恨过一个人，就是想“宁愿玉碎也不为瓦全”，哪怕自己不开心也要拉着他来垫背，总之我要他付出痛的`代价。突然有一天，我累了，这样是为了什么呀他痛了，难道我就快乐吗?佛说，有因必有果!犯下的错就由时间来给他苦果吧!大家都说，做过妈妈的人更懂的宽容，或许是的，不过遗憾的是我没有，以后我也会的，我非常的喜欢小孩，一定会努力做的很好。

学会去原谅，没有什么是一辈子忘不掉的，当然也没有什么是一生不变的依靠，心如止水、随遇而安、淡然看世界、重要的是好好爱自己!

Recently, global warming has become a hot topic among people. It results

from serious air pollution. As the environmental pollution is more and more

strict, the temperature of all the world has dramatic increased. Gradually, some

disaster such as drought, floodandGlaciers Melting follow. How terrible it is!

Therefore, we need to protect our earth and fight against the disaster

together.We should start from the trivial side. Making contribution to

protecting our home.

When I was younger , I went through an thing which deeply influence me.

One day,I went to school as Usually. All of a sudden,I heard a voice

crying.I knew there were something wrong . So I walked towards the direction of

the voice .Then I found a child and his mother wandered off.My heart full of

compassion . So I decided to help him find his mother , and I took him to the

police station nearby . Then I went to school in a hurry , but when I arrived,I

found I’m still late . After my teacher’s preaching , I went back to the

classroom .I was so upset.

In the afternoon, my teacher asked me go out,he said he had wronged me. And

then I saw the child’s mother,she thanked me a lot,and I smiled shyly.

After the thing,I feel very happy to do good things,and I believe that

“give cake and ale to perfect soul”.

仙女湖是肇庆的一个重要景点。那里一年四季景色宜人、风景优美。任何人去到这美丽的地方，都会流连忘返、难以忘怀。

春天，桃花在人们不注意时悄悄开放，在风中轻轻舞动，让人们欣赏自己美妙的身姿。绿油油的柳树也不甘示弱，一条条柳枝像春姑娘绿色的小辫子，真美丽!小草也从土里探出脑袋，换上嫩绿的新衣裳，好奇地打探着世界的每一个角落。

夏天，各种各样的树木长的葱葱茏茏。人们坐在树下乘凉，说说笑笑，欣赏湖边的风景。还有的人在湖上划船。湖上还有一群活泼可爱的小天鹅，他们有的和小伙伴们在碧绿的湖水里嬉戏打闹，有的在静静地欣赏自己映在水里洁白美丽的倒影，还有的在湖面上开心地玩耍，弄得水花四溅!

到了秋天，湖边的菊花欣然怒放，更引人注目了!有的菊花低着头，像个害羞的小姑娘;有的菊花挺着胸、抬着头，像一位娇气的小公主;还有的菊花两朵靠在一起，像是在说悄悄话。风一吹，她们发出“沙沙”的声音。我想，她们是在比美吗?菊花不仅美，颜色也多，有黄色的、粉色的、紫红色的……漂亮极了!菊花不仅颜色多，花瓣也是千姿百态呢!有的花瓣是长条形的，有的是椭圆形的，还有的是针一样的形状。花朵有的含苞待放，有的才开了几片花瓣……这些菊花不禁让我想起了一句诗——不是花中偏爱菊，此花开尽更无花。

冬天来了，天气变得更冷了，所有的花儿都凋谢了，只有腊梅不害怕寒冷顽强地开着。那小小的黄色花朵散发出浓浓的花香，引来人们的一阵夸赞。就像人们说的那样，腊梅的香味是来自寒冷的冬天。

啊，美丽的仙女湖，我愿变成一只小鸟，为你轻声歌唱;我愿变成一道彩虹，挂在你蓝蓝的天空;我愿变成一盏明亮的灯，把你照得更加光彩夺目!

Many animals are in danger of dying out. As is shown in the chart, we can

see the number of animal species decreases faster and faster and this trend will

continue. From 1980 to 2010, at least 1 million animal species have disappeared.

Worse still, more and more wild animals are in great danger. It is not a piece

of sensational news; it is a fact, a harsh reality. Unfortunately, we may not

see these animals in the near future.

From the second picture, we can find some reasons. Why is the number of

animal species declining year by year? Apparently animals have become victims of

fashion industry. Animal skin has been used to make fashionable clothes and

these clothes sell at a high price. So some greedy people begin to kill animals

in a large quantity. This irresponsible behavior not only breaks the balance of

nature but also endangers the living environment of human beings.

As far as I am concerned, something must be done to stop this illegal

action. We believe "no buying, no killing". First, we must make concerning laws

to protect these animals in danger. Second, we must take some measures to

protect animals effectively. Animals are our friends and part of our

environment. Third, we should raise peoples awareness to protect animals and

our environment. In this way, we can build a harmonious society and ensure a

sustainable development.

An essential quality for young people is diligence.Nowdays,the issue on the

most important personal quality of young people is highly debatable,and ideas

vary from peerson to person. Some would claim that confidence is the most

essential. But for my part,the most essential quality for young people is

diligence that helps us a lot.

Diligence enables us to academic results. As we all know,academic results

requires lots of researches. An ancient calligraphy,named Wang Xizhi,devoted

lots of his time practicing writing. As is known to us all,he dried his pool

with his writing brush day after day. Though diligence,he became the greatest

calligraphy,finally.

Deligence helps us to achieve better scores in school. Last semester,one of

my fellow students failed to pass the Listening cours. In fact, questions set in

that paper were not very difficultt. If she had spent a little more time

listening rather than watching TV at her dorm,she could have passed the exam. On

the other hand,one of my roomates worked hard every day and got a high

score.

Diligence provides us more chancs to be succeed. As the saying goes “The

early bird catch the worm”. A diligent man may get up early and have more time

to improve himself. And that is the key to be succeed. If

we spend some time observing people around us,we can easily find some

people,just like Li Jiachen,are diligence and successful.

All in all,as a young people,once we have cultivated the essential quality

of diligence,we can achieve academic achievements,get a high score and have more

chances to be succeed. Once we have this essential quality:diligence,it do helps

us a lot in many ways.

Almost all of us heard the story “Here Comes the Wolf” when we were little

kids. What we can learn from the story is that we must be honest. However,

there’re lots of phenomena of dishonesty nowadays。

Being dishonest does great harm not only to other people but also to

yourself. Take the case of fake milk powder for example. After drinking this

kind of milk, the babies had big heads while their legs and arms were still

thin, which badly affected their health. To our great relief, the producers got

accused and punished for all the serious consequences in the end。

Having the reputation of being honest and reliable will make other people

trust you, which will provide you many benefits and give you opportunities that

others may not get. Being honest, you will find it easier to cooperate with

others and people will be friendly to you and support you. In a sense, if life

is a long journey, honesty will be the backpack that should be taken along all

the way. Let’s pick up our “backpack”—honesty, and start the wonderful

journey!

It was the first day of our summer holiday. All of us were very happy. Why?

Because we have one months to do things we love to do. We are free.Although we

have some homework. But we can finish them in several days. And the rest time we

can make good use of. My god! We have been very tired after hard studying. In

winter holidays, I want to have full sleepand eat good food in order to

replenish myself. Last but not the least, I will have a good rest.

The Advantages of Travel Alone

I like to travel to different places, I can see the beautiful scenery and get to know the different cultures. My friends and I always travel together, we make many plans in advance. But the plans will always be interrupted by all kinds of unexpected incidents, like the bad weather, the holiday being cancelled, so we have to spend another time to wait for the trip. Traveling alone can ignore these problems, I can go to travel whenever I want, I just need to pick up my backpack, and then buy the ticket. It is so free, I don’t have to wait for others, I can go to the places I want to. Traveling alone is good.

我喜欢去不同的地方旅行，我可以看到美丽的风景和了解不同的文化。我总是和朋友一起旅行，我们提前订好很多计划。但是计划总是会被各种各样意想不到的事件打断，比如天气不好，假期被取消等等，因此我们不得不花时间等待下次的旅程。独自旅行就能忽视这些问题，我可以随时去旅行，只需要背起背包，买上票。那是多么的自由，我不用等其他人，去我想去的地方。独自旅行真好。

它，是我们在美好的学习、成长的道路上最忠实的朋友之一，它用一如既往的冷静，凝视着渐渐长大的我们。没错，它，就是黑板。

黑板，给我带来了又刻下了多么美好的回忆。它像一位满腹经纶的学者一样，把快乐和知识带给了我们。每每回忆它们，我们心中便充满了温馨，犹如和它结伴归故里――学校。

上个月的数学课，仍像一场电影，我一遍又一遍地回放着，忍俊不禁。

那节数学课，简直可以爆笑全校了!我们的数学老师要求几个学习差的同学上黑板来做题，其他人就在下面快速完成任务，再等在黑板上做的同学完成。

我正埋头苦干，突然班级里发出一阵爆笑，我定睛一看，原来是小施同学在做一题分数简算时，把题目也抄错了，所以做出来错得离谱。

见他一脸不知所措，我也笑得肚子疼，他手忙脚乱地擦去几个数，又重新写上了，还在黑板上仔细地算着。黑板似乎也因为他的粗心生气了，就不让他做对。我们像在看“黑板耍猴”似的，笑得花枝乱颤……

小施终于发现了他的错误，把题目改正后，又开始算了起来，可黑板偏不让他做对，这一遍他依然做得一塌糊涂。

最后还是数学老师亲自上阵，才把黑板这位“老顽童”给镇压住。

黑板虽调皮，却又像一位慈祥的长者，默默地奉献着。

有一次我们组扫地，扫完时挺早，根本不想回家。我们便拿起粉笔，在黑板上写下我们的个性签名和心里想说的话，对黑板倾诉着我们的爱，我们的烦恼，更多的是对学校的热爱，黑板则在一旁慈爱地看着我们玩耍。

黑板呵，你见证了我们几年的成长经历，除了你，谁更了解我们?

Every day, we can see the figures of the volunteers. Actually, they have

formed a kind of scenery of the city. Some people hold that volunteering is

merely a waste of time, because the volunteers have no gains with pains.

However, I believe that doing voluntary is quite rewarding.

In the first place, we can put into practice what we have learnt before,

for instance, when we were asked by a foreigner about the way to some place, we

could practice our oral foreign language, it’s definitely a good opportunity to

express ourselves in a foreign language correctly and clearly.

In the second place, we could make a lot of new friends while we are

volunteering As a proverb says, “At home one relies on one’s parents and outside

on one’s friends”, so it is never a bad thing to have lots of friends.

Finally, helping others is a good way to make you feel happy and when you

help others solve a problem successful, you will feel fulfillment. In this

sense, we reap a bountiful spiritual harvest by doing voluntary work.

On the whole, we can benefit a lot by engaging ourselves in the voluntary

work. Therefore, I suggest those that have abundant spare time registering as

volunteers for the welfare for the public.

在我的心里，家是菜园，我是菜苗，一个茁壮成长的苗，而陪伴我十三年的家风则是甘露、雨滴。是家风耐心的历经春夏秋冬滋润我，没有家风的滋润，我就不能够茁壮成长。

家风伴我从懵懂无知坐向成熟，一步步在人生的阶梯上踏上脚印，是它塑造我的无形力量―家庭的生活方式。在模糊的记忆中，妈妈教我懂礼貌，尊老爱幼，诚实守信，助人为乐等等。品质方面严格把关。

时间不紧不慢的流逝，事情一次一次的发生。外面闪耀的阳光直直的射进窗户，我们家的争议声又一次直逼耳际：

“你说你都多大，干什么都干不好。瞧瞧，让你给你倒杯水，干嘛倒那么满，撒的到处都是。”一向宠爱我的妈妈一边擦着桌上的水，一边又开始唠叨。虽然说，妈妈的“话匣子”有点烦人，但勉强算得上是“音乐”。就听下去吧。原来今天早上我家来位做客的阿姨，妈妈命令我去倒一杯水给阿姨喝，天有不测风云，人有旦夕祸福，不料，我的手不小心抖一下，水就倒满。有点不小心，不过我不是故意的。阿姨走后，妈妈的“低音小喇叭”开始不停地的播放，做事稳重，不要三心二意。我只得改正。

“那么大，连点规矩都不懂，客人来也不知道打声招呼，只顾忙自己的。”妈妈一送走客人，回来就又“赠”我一句。我怎么这么倒霉，“……!”长篇大论过后，妈妈竟然一点点也不累：“要知道尊重别人，得有礼貌。”从此以后，家里来客人我一刻也不敢怠慢，急忙左一声“阿姨好，”右一声“叔叔好。”

我在妈妈的话匣子里学到懂礼貌，尊重他人，做事专心，我伴着岁月，年龄不断增长，妈妈却毫不松懈。告诉我：“这些事情虽然微不足道，是‘鸡毛蒜皮’的小事，但可以直接影响你的成长。”我的家风由我的妈妈培养出来，一步一步，一件一件。

没错，无形中好的家风的养成，是正能量的传递，也是以后对自己教育的回馈，只要家风好，国风才会好。

我们家的家风，愿它常驻我家。愿那不辍的改进之风飘在中国民族的上空，飘进千家万户之中。愿我的家庭会因它变得更充实，更美好。

Since we went to school, we have been educated to be polite, no matter to

the young or old people. People follow the manner rules and have a nice

communication between each other, but some people ignore the rules and they

treat their rude behaviors as something cool. Today, people advocate the

individuality, so the young generation wants to do something different and catch

peoples attention. For example, they dont care other peoples feeling and

criticize others as they like, or just interrupt when other people is talking,

they just show what they want to say and they believe they are special and cool.

This is very rude behavior that they dont respect others and have the wrong

idea about individuality. We can do something special on the base of respect

others and follow the rules, or we are just the rude people.

书这个字，我想大家一定都现熟悉不过了，不过，现在有的学生最讨厌书，像你知道未来的书是怎样的呢?这时我想大家的脑子里已经有了个大大的问号吧!要是你们知道未来的书是怎样的，我想你们对书的态度会有翻天覆地的变化，就让我来为大家讲讲未来的书是怎样的吧!

未来的书功能可大了，外形像手机一样，跟纸那么厚，却比纸要硬得多，比铁还要硬，怎样都是毫发无损。就这个小小的机器，就能打电话、听歌、上网、玩游戏最重要的是，这里面什么书都有，比得上十个大图馆。你们看多么的精妙绝伦。

这本书能打电话，而且能在全球通话，这一点就比手机电话要好得多了吧!这本书还有一个优点，就是通话时能看到对方在干什么，能看到对方的脸，这样即使亲人朋友离得再远，两人也能天天见面了。

这本书还能上网、听歌，就给了人们娱乐时间了，在搭车时，也能给枯燥的行程增添点乐趣了，要是父母怕孩子们整天抱着它上网，影响学习，那你就错了，这个机器有心灵感应的功能，如果有人沉迷于此，就会自动关机，并且给你设定时间，如每星期只能打五小时，这样，父母就不用担心了，更何况这还能查资料，有助于孩子学习。

书，当然以看为主了，这个机器里有十多个大图书馆。有漫画故事还有学生要学的科目的书，上学时，就不用背着重重的书包了，让人更加轻松，也可以旅游时带着它，会更加的方便。

如果真的有这样的书，那么大家肯定能空出的时间去做别的事，这会让人类的生活变得方便，希望那些科学家真的能发明出这样的书来，那肯定会轰动全世界的。

每年春节到来的时候，家家户户都张灯结彩，贴上了美丽的窗花，各种各样的大“福”字和春联，到处都是喜气洋洋的.。

Every year, when the Spring Festival comes, every family will put on lights

and decorations, paste beautiful window flowers, all kinds of big "Fu"

characters and spring couplets, which are full of joy.

然而2020年的春节却完全不一样，一场不见硝烟，不闻炮响的战争打响了，不宣而战，“新型冠状病毒“肺炎席卷而至，各地各部门积极响应，共同对抗疫情。白衣天使们，志愿者们……许许多多奋战在一线的勇士们，他们作为生命的逆行者，开启了2020的新篇章。

However, the Spring Festival in 2020 is totally different. A war without

smoke and guns has started, and the "new tubular virus" pneumonia has swept

through. All departments have responded positively and fought against the

epidemic together. Angels in white, armed police officers and soldiers,

volunteers. Many brave men are fighting in the front line. As the lifes

reverser, they have opened a new chapter in 2020.

作为少先队员的我也应该积极奉献自己的一份力量，做到今年过年，不串门，不聚餐，督促家人做好卫生防疫，不得已去公共场所必须规范戴好口罩，使用过的口罩按规定丢入“有害垃圾“桶。注重个人卫生，常通风，勤洗手，不随地吐痰，打喷嚏咳嗽时应做出正确遮挡。在家开展学习，加强锻炼，保护野生动物。

As a young pioneer, I should also actively contribute my own strength to

this years new years Eve, do not visit the door, do not have a dinner party,

and urge my family to do a good job in health and epidemic prevention. I have to

go to public places and wear masks in a standardized way. The used masks are

thrown into the "hazardous waste" bin according to the regulations. Pay

attention to personal hygiene, often ventilate, wash hands frequently, do not

spit everywhere, and make correct shelter when sneezing and coughing. Study at

home, strengthen exercise and protect wild animals.

2020年的钟声已经敲响，万紫千红的春天已经不远了，我想信在全国人民的共同努力下，我们一定能打赢这场“战役“，迎来我心中美好的2020!

The bell of 2020 has been ringing, and the spring is not far away. I

believe that with the joint efforts of the people of the whole country, we can

win this "battle" and usher in a better 2020 in my heart!

Now the earth is in bad condition。 For example， in some places， the air and

water pollution is so serious that it causes many deaths。 At the same time， many

animals and plants are in danger because of the destruction of their

habitats。

Luckily， we human beings have realized the problem。 On April 22nd， millions

of people across the world do something good for the earth。 Some clean up

beaches and water， some pick up rubbish， others give speeches to call on more

people to take action。 But can we save the earth only by one day’s work? The

future of our planet depends on our efforts。 What we should do is to make every

day Earth Day。 Only by taking good care of it every day can we hope to live in

harmony with nature。

上次参加王子行的生日聚会，结束的时候他给我们每个同学都发了一个小礼物，我的小礼物就是环保的“盐动机器人”。

“盐动机器人”，顾名思义，就是光用盐水就可以驱动的机器人，完全不需要电池，很神奇吧?而且，只要滴几滴盐水就可以让它走动，很环保。

先说说它的结构吧。这个迷你的机器人是由一个底盘，一个电池盒，一个电池盖，支柱，枢轴，两个机器手臂，电池片(包含铝片，布片，碳片)，马达和轮子组成。

为了让它能动起来，可以说是大费周折。光是调盐水，就花了我不少时间。调盐水必须要达到“饱和”的标准，让机器人动起来就更是难上加难了。

刚开始调盐水的时候，盐水仿佛在和我“作对”。起先，我一点儿也不知道“饱和”是什么意思，问了妈妈才恍然大悟。原来是盐水浓的不能再溶解更多的盐了，那才叫“饱和”。第一次，我往水杯里加了一勺盐，一搅拌，白花花的盐就消失了，再加一勺，一会儿又溶解了，就这样反反复复加了很多勺盐以后，总算水杯里的水“吃”不下再多的盐了，盐粒沉到了水底。我用滴管吸满了盐水后滴在了组装好的机器人电池盒上，可是，机器人纹丝不动。我看了下说明书，发现可能有很多问题会造成机器人不能动。于是我像一个工程师一样，一个个进行原因的排查。我先多滴了几滴盐水，机器人不理我，我想给它个助力，帮它启动，可当我滑完了它的轮子后，它还是不动。我担心是不是铝片与碳片接触了，觉得换一个大一点的布片应该会好些，可是换好了，它还是不动。为了让弹片与铝片和碳片分别有更好的接触，我就把弹片使劲往下按了按。“呼呼”，功夫不负有心人，这个小家伙终于动了。可真是花了我一大笔时间啊!但机器人把我弄了个措手不及。只见它如飞出去的箭一样一下子跑到了餐桌的边缘，幸好我在危急的时候拦住了它，要不然它就会被摔得粉身碎骨了。如果那样，我花那么长的时间就是前功尽弃了呀!

大家说说，我的“盐动机器人”有趣儿吗?
