Guo Jingming is a famous writer in China. I think all the students have

known him. He is also my favourite writer. He was born in 1983. He has published

many books, such as "Visionary"," The Summer Still Doesnt Come"…These books are

very touching.

I often cry and shed bitter tears while I am reading his books. I thought

he was a pessimistic person but now I think he is sensational person. He doesnt

want to grow up judged by this. I think he is pure and naive. Although he is a

writer, he studies well.

I admire him very much. His words are common, but they make people feel

quite close to him. I hope he can write better articles and I want to be a

writer like him when I grow up.

and ends on the the full days later. In china,people regard Spring Festival as

the most important thing.People studied and worked throughout the year.No matter

how far and how busy, they must do their best to go back home.Thats a tradition

and now becoming a habit. During this time,transport is extremely busy.Although

the way is difficult,it cant reduce the urgent feeling of going home.I cant

describe this feeling,only the people that experienced it can

understand.Actually,on one hand,people miss their family,and they need to get

comfort in the family.On the other hand,getting together is a symbol of

blessedness and auspiciousness.People in other country dont have this

consciousness that going home is necessary.For example,American could celebrate

the Christmas in everywhere they like or with anybody.This diversity is

occasioned by different culture between two countries.

On Spring festivals eve,the whole family prepare the dinner.Of

course,dumplings is essential.In the

evening,family members always sit at the television and watch Spring

Festival Gala.At 0:00,people set off firecrackers and fireworks,at the same

time,children pay New Year,s call to old people.The old people give money to the

children as a lunar new year gift.Usually,people stay up late or all night.

On lunar New Years Day, the Chinese family eat vegetarian dumplings which

imply they will plain and neat in this year. People change their new

clothes,this stands for a new beginning.Next,people visit relatives with some

gifts.The second day is son-in-laws festival,the husband and married women

visit their side of the family.In a word,Chinese attach great importance to

Spring Festival.

篇3:难忘的童年趣事主题初中优秀

全文共 1215 字

+ 加入清单

回想起童年,那还真有趣。我和文文姐、花飞哥在外婆家的那段美好时光,尤其是姐姐和哥哥带我进猪圈的那件事,始终让我难以忘却。

那是暑假的一天中午,在大人们都熟睡时,我和姐姐、哥哥三人组的疯狂计划便开始执行:我们决定到猪圈一探。我们蹑手蹑脚地低着头走,花飞哥在前面,我在中间,文文姐在后面。我们穿过阴森小道来到后院,刚见到一丝温暖的阳光,密密麻麻的苍蝇、蚊子就向我们袭来,我一拍就死了好几个。呀!一只大蜘蛛!我们的脚走到一半突然全停住了,眼前有只大蜘蛛在枇杷树最显眼的地方织了一张大网,足有一平方米那么大,我们对视了一下,扭头就跑。太可怕了,我的记忆里那只蜘蛛有半个手掌那么大,背上有红黄相间的纹条,大概八条毛茸茸的粗而有力的脚站在网的中间,我看见它大概六只黑珠子似的眼睛好恐怖。姐姐和哥哥向哪儿逃,我也向哪儿逃,最后竟逃到目的地。

由于我刚才被那只大蜘蛛吓倒了,不论怎样也不愿进猪圈了。可是哥哥却满怀期望,因为他可以看到出生满七天的小猪猪了。我看着哥哥打起了坏主意,所以,我便答应进猪圈。

瞧,一头肥肥胖胖,比我们三人还重的老母猪睡得可香了,我们的心跳都伴随着它的呼噜声一上一下,一上一下。旁边的小猪也都睡了,胖乎乎的脸蛋一个比一个可爱,只怕非常爱干净的女孩子会拒绝吧。它们有的趴在妈妈身上,有的睡成四脚朝天,更可爱的是有一个小猪睡在食糟里呢。

哥哥小声地说:“我做为你们的哥哥,由我来捉猪,你们在旁边保护我。冲啊!”我表面上答应了,但心里却想着呆会儿给哥哥来个“狗吃屎”——我哥哥属狗!

哥哥翻过拦猪矮墙,姐姐也翻过了,我虽然爬上去了,但是差点儿掉进食糟里。哥哥早就瞅准小猪猪了,它全身乳白,两只垂猪耳,一只超有型的鼻子。哥哥抱起它就逃,没想我和姐姐溜得比哥哥还快。哥哥翻了墙,手里的小猪猪“嗷嗷”直叫,我真不明白它为什么一点也不挣扎,它真像我被人欺负时好种样子。对了,“狗吃屎”怎么忘了?唉!我们才逃到拦墙外就停了,这时哥哥朝我们眯着眼笑,表示成功了,哪里哪里,我们才刚走半步,腿就开始发抖,因为哥哥一旁的一个庞然大物正气势汹汹得用两只前蹄蹬在拦墙上,本来小得像珠子似的眼睛,现在睁得比那只蜘蛛还大,正瞪着哥哥,他却浑然不知,还问我们:“可爱吗?”

我们早就被吓得呆若木鸡,只能动眼珠子,哥哥还眯着眼笑,幸好哥哥起身想放它回家。哥哥也真倒霉,刚转过头他就正好挨到那只老母猪的鼻子了,老母猪忍无可忍,它张开嘴一声怒吼,把哥哥吓得不由自主向后一跳,手差点儿松开,眼睛也被吓睁了,他第一个看到的就是一个充满杀气的怪物。哥哥真厉害,这时他也敢动,他一小步一小步移到离老母猪稍微远的地方,刚才还站得笔直的,现在大幅度170°弯腰把小猪猪送回家,他差点儿连猪带人都掉进猪圈,然后“唰”地站直,之后消失得无影无踪,我和姐姐看着哥哥走了,我们也跟着逃走了。

大人们因为被刚才好大怪物的怒吼声吵醒了,出去看个究竟,刚到门前就看到文文姐姐和我大哭,花飞哥却在傻笑。

保护环境英语作文篇1

Through observation, I found that plastic bags on peoples harm and pollution is very large。 People often use plastic bags: mother to buy food and plastic bags; to shopping malls with plastic bags; in the restaurant to eat rice is also packaged with plastic bags to take home; even I buy stationery also with plastic bags。 People do not know what they do to the environment caused by pollution, their own body caused any harm。 Such as: people often put useless plastic bags thrown into the garbage, plastic bags in the rubbish will be smelly, so that the pollution of the air。 People also throw plastic bags anywhere, a wind, plastic bags flying in the sky, the branches also see the tree is a plastic bag, and even the river there are plastic bags。 This plastic bag in addition to pollution of the air, but also polluted our water resources。

We should raise peoples awareness, tell us the neighbors and friends and family together to beautify our environment。 On the road to see the plastic bag quickly picked up, immediately took it to the garbage disposal。 We want to start from my use less plastic bags, so that my mother every day to buy food or shopping when they first take their own bags, this is not very environmentally friendly? Or can use their own holding things as far as possible by hand, no plastic bags。

As the saying goes: "to protect the environment, everyone is responsible" We have to protect the home environment out of a force。

通过观察,我发现塑料袋对人们的危害和污染非常大。人们还经常用塑料袋:妈妈买菜用塑料袋;去商场购物用塑料袋;在饭店里吃不完的饭也是用塑料袋打包带回家;连我买文具也用塑料袋。人们却不知道他们这样做对环境造成的污染,对他们自己的身体造成了什么危害。如:人们常把没用的塑料袋扔进垃圾堆,塑料袋在垃圾里会发臭,这样就污染了空气。人们还把塑料袋随地乱扔,一刮风,塑料袋在天空中漫天飞舞,树枝上也看到满树都是塑料袋,就连小河里也有塑料袋。这样塑料袋除了污染了空气,还污染了我们的水资源。

我们应该提高人们的认识,告诉我们身旁的邻居和亲朋好友一起来美化我们的环境。在路上见到塑料袋就连忙捡起来,马上把它拿到垃圾场处理掉。我们要从我做起少用塑料袋,让妈妈每天买菜或购物时都先拿上自己做的布袋,这样不是很环保吗?或者能用自己手拿的东西就尽量用手拿,不用塑料袋。

俗话说的好:“保护环境,人人有责”我们也要为保护家乡环境出一份力。

篇7:高二语文作文环保主题

全文共 827 字

+ 加入清单

每个人都希望有一个良好的生活环境,这环境要求既清洁,又舒适,又健康。而一个清洁舒适健康的环境需要大家一起努力共同保护。

我们都知道白色污染会影响土壤、空气和生物,其危害非常大。比如,填埋废弃塑料制品的土地,会因为塑料不易分解而使得土地板结,不能生长庄稼和树木,而焚烧这类垃圾又会释放出许多种化学有毒气体,尤其是二恶英,毒性极大。今年6月1日全国开始的限塑令使得人们普遍认识到塑料袋的危害,而且因需付费购买,所以在使用的数量上将大大减少,从长远的角度看,这对环境的保护是有利的。

另外一个关系到环境保护的问题是汽车尾气污染。这种污染随着汽车数量的增多而日趋严重。经分析,汽车尾气中含有的大量有害气体如铅、一氧化碳、氧化氮等对人体的危害非常大。还因为汽车尾气一般在1.5米的高度以内最浓,所以儿童受到的危害最大——即铅中毒。吸入过多的铅会导致头晕、头痛、失眠、记忆力减退等问题,而儿童铅中毒智商会降低。所以为保护环境有的城市推行“公交日”,号召人们少用私家车多乘公交车,其实如果不是太远的路程,倒是应该提倡安步以当车,因为步行对身体非常有好处。

保护环境方面还包括节约能源问题。“节约能源,每个人都能在举手投足间做到。”比如,刷牙时不要让水一直在流淌,公共场合及时关闭水龙头,都是节水方面的好习惯;再比如随手关灯,空调温度调到适宜(夏天不过低,冬天不过高),则是节电的好习惯。一个人是否节约,不在于他是否在乎水电费用高低,而关键在于自身意识的提高,所以光靠提高价格是不能解决什么问题的。主要是让所有的人都明白一个道理:我们决不能透支环境资源,要给下一代留下点儿。

保护环境当从我做起,从身边小事做起。我们每天都要扔垃圾,既不应提倡随手乱扔也要注意各种生活垃圾的分类处理:比如电池应扔入专门的回收箱,塑料、纸张、易拉罐等能回收的要卖给收破烂的(他们不光赚了钱,还保护了环境,功不可没!)。

综上所述,保护环境人人有责。我们应担当起责任,努力为自己为他人创造更美好的环境!

篇8:初中生应把握中考英语作文的评分标准

全文共 434 字

+ 加入清单

写作,作为中考英语三大重点模块之一,满分15分,是整张试卷中最难拿满分的部分,也是很多同学头疼的地方。

中考英语作文分四档:第一档(15—13分),第二档(12—9分),第三档(8—5分),第四档(4—0分),每一档都有具体的评分细则。

乐加乐中考研究中心胡赛楠老师强调:“充分认识到写作评分标准的重要性,按照标准要求规范自己的写作并多加修改,才能做到知己知彼、百战不殆。”

首先,审题要准。要点齐全,8分以上;要点不全,直接进入三类文;

其次,一档文应“观点正确”“语言准确”。“观点正确”是文章要积极向上,不可出现反动消极言论;所谓“语言准确”是要忠诚于词汇的惯用法和辨析,要有非常好的文字功底才能达到。

最后,第一档的“句式多样,词汇丰富”与第二档的“语法结构和词汇基本满足文章需要”不同,要求更多的句式和词汇。因此,应在作文中适量使用定语从句、感叹句、倒装句、祈使句等特殊句型;此外,一二档文的差别还在于“逻辑性”,在句式、词汇都相当的基础上,逻辑性强的文章容易得高分。

清明的前一天,各大超市可火了,人们推着购物车,仔细地挑选祭祀用的糕点、水果和糖果,生怕给长辈的祭祀品不够好。妈妈每年都是这个购物团中有力的一个,你看她挑好满满一车的祭祀用品,排在长龙般的队伍中,然后急冲冲地回家整理,就怕出一点点差错。

经过漫长的路途,来到久违的家乡,吃上几个美味的青团是再惬意不过的事了。农村人做青团也特别热闹,七姑八婆聚在一起,边做边谈笑风生。

青团是由糯米粉、小麦粉掺在一起,做成皮;馅一般分甜咸二种,甜的基本上都是豆沙馅,香香甜甜,吃起来甜而不腻;而咸的一般用笋、猪肉、花生米等炒在一起,咬起来脆生生,闻起来香喷喷。再在青团外面包上二片“青叶娘”,往锅里一蒸,清香扑鼻而来,咬一口,香味就在你的嘴里弥漫开来,让你吃完一个还想吃一个。

清明节的重点当属祭祀了,走着不常走的崎岖山路,欣赏着不常见的乡野风光,一路上倾听春风的歌声,我们来到了一座座长辈的坟茔前点上香和蜡烛,倒上三杯陈年老酒,摆好精心挑选的祭祀品,再在坟前全心全意地拜一拜,保佑自己平平安安,万事如意。

不过,现在人们防火意识越来越高,烧冥币、放鞭炮等习俗逐渐被敬献鲜花等文明的祭祀方式所取代。虽然上了年纪的奶奶还是十二万分的不高兴,但也拗不过我们的集体劝说。我呢,总是亲手采摘一些野花,扎成一束,恭敬地放在坟前,看到这个,奶奶也笑了!

如果你的家乡有竹林,那挖笋也是别有一番乐趣的。

扛上锄头,来到竹荫下,在层层落叶中找寻那冒尖儿的笋。一旦找到,就会引来无数羡慕的眼神,然后你抡起锄头,要非常有技巧地刨开笋周围的泥土,最后插到笋的根部,用力一撬,一个胖胖的笋娃娃就咕碌碌滚了出来。带上自挖的竹笋回家,炒个小菜,不是很有情趣吗?

Last Qingming Festival,i return home to worship my grandfather.Qingming

Festival is a folk Festival.In the past,the Qingming Festival was called "Arbor

Day". But Today, Chinese visit their family graves to tend to any underbrush

that has grown. Weeds are pulled, and dirt swept away, and the family will set

out offerings of food and spirit money. Unlike the sacrifices at a familys home

altar, the offerings at the tomb usually consist of dry, bland food. One theory

is that since any number of ghosts rome around a grave area, the less appealing

food will be consumed by the ancestors, and not be plundered by strangers.

With the passing of time, this celebration of life became a day to the

honor past ancestors. Following folk religion, the Chinese believed that the

spirits of deceased ancestors looked after the family. Sacrifices of food and

spirit money could keep them happy, and the family would prosper through good

harvests and more children.

篇15:以圆为主题的作文初中

全文共 709 字

在原来,圆规并没有被发明出来,那么古代人,是怎样画圆的呢?在课堂上,我们猜想,人们曾经可能用过这样的几个方法:其一,是一只手的大拇指固定不动,中指张到最大,围绕着大拇指旋转一周,但这个方法不能保证大拇指的位置是否移动,显然这个方法是行不通的;其二,是用水杯的底部,围绕着它,画一个圆,这个方法能够保证圆的准确性,但无法改变大小,还是不够完美;其三,张开一只手臂,贴在黑板上,抡起来画一个大圆,这个方法更加行不通,圆太大了,连黑板都没有了它的容身之地;其四,找一根鞋带或细线,一头系上铅笔,用手固定住另一头,将线拉直,用铅笔围绕着另一头旋转一周,一个完美无瑕的圆就画好了。这个方法最大限度地模拟了圆规,既能控制大小,又很精确。

而现在,圆规已经很普遍。学会使用圆规,也是很重要的:首先,用右手拿起圆规的把柄,将两脚分到指定的半径距离,然后,将尖脚扎在圆心上(不能移动),用力旋转,最后,按要求标圆心、半径和直径。

那么,与圆有关的概念又有什么呢?我们认为应有以下几点:1、圆心(O):用圆规画图时,尖脚所在的点。圆心确定圆的位置。2、半径(r):连接圆心和圆上任意一点的线段,有无数条。半径决定圆的大小。3、直径(d):通过圆心并且两端有在圆上的线段,有无数条。4、在同圆或等圆中,所有半径等相等,所有直径都相等。5直径长度是半径的2倍:2r=d;半径长度是直径的?;?d=r。6、圆是轴对称图形,直径所在的直线就是圆的对称轴。圆有无数条对称轴。而关于圆的周长的,有以下几点:1圆周率(π):是圆的周长与直径的比值。是无限不循环小数,π=3.1415926535……,实际应用通常取π=3.14.2、公式:C=πd=2πr。

应对自然气候的恶化,于是人们从日常的行为开始保护地球家园,开始了低碳生活。

“叮呤呤……”,随着一阵清脆悦耳的铃声,睁开朦胧的睡眼,期望的晨曦射进窗户―――新的一天又开始了!早上的洗漱穿戴一如既往,但洗脸刷牙的水用得少了,只为节约水资源;背上书包,和走下楼,钻进小汽车里送上学,们家的小汽车不再是加油的汽车,而是环保的加气汽车,能够减少碳排量。

跨入校门,欢声笑语依旧,空调等大功率用电设备已闲置多时,取而代之的是高科技的太阳能取暖设备,就连电灯用的电也是用的风能电力。

放学了,校门外很是喧闹。以前的零食小摊已不复存在,此时因为同学们为了保护环境已不吃零食了,因为零食在制作过程中会有超多的碳排出。

回到家,迅速地做完作业,和其他同学一样为了不熬夜,少开电灯节约用电。

闹钟也是用带发条的那种代替电池的那种,因为制造过程中产生很多碳,废旧的电池也对地球土壤成份具有很大的破坏作用。

吃晚饭时炖肉用的酒精炉烧的是用麦秸等原料制作的生物酒精,电视机也集中到一齐看,有时会因为频道的喜好产生分歧,但为了节约用电,还是透过民主的举手表决方式,少数服从多数来决定。

地球,我们这些祖国的花朵都爱护着您,唯一的期望就是让您斑驳的面庞重新光彩照人,不再有吞噬人类的海啸地震,空气能够清新起来,天空能够湛蓝起来,大地能够绿化起来,此时构成人与自然的和谐统一。
