记得父母教导我们时常说：“我们吃的盐比你们吃的米还多,我们过的桥比你们走的路还长.”我们却总是那般年少轻狂,不以为然.我们忽略了当岁月无声溜走时在他们面庞和两鬓留下的痕迹,自然也忽略了许多无价的智慧经验在他们心田积淀.他们总愿意对我们倾之所有,而我们总固执地认为这已不合时宜.我们便像初生牛犊,乱闯乱撞,直至遍体鳞伤,犄角流血,然后奔向他们,头枕他们的胳膊,舔舔伤口,又继续前行.
我们怀着感激的心接受这一切,听他们的一席话,远胜于读十年书,受益匪浅.我们怀着细腻的心感受着一切,感受亲情的无私与毫琵保留.
时间的流逝,许多往事已经淡化了,可在历史的长河中,有一颗星星永远闪亮,那便是亲情.时间可以让人丢失一切,亲情却割舍不去.即使有一天,亲人离去,但他们的爱却永远留在子女灵魂的最深处.

他在课本剧《狼和小羊》中扮演了一个角色.

我国在世界上扮演的角色越来越重要,这是不争的事实,我国的经济已经成为继美国之后的第二大经济体,而且中国的发展势头和前景相当好,如果国家的大的战略不出意外,大概在2020年左右中国的经济总量将超过美国成为世界第一大经济体.
政治方面中国是联合国安理会五个常任理事国之一,是安理会常任理事国中唯一一个发展中国家,第三世界国家,在很多方面代表了广大的发展中国家的利益,但是由于中国最近30年只是注重发展本国经济,降低了对第三世界国家的帮助,所以虽然中国现在比以前能力强了,反而没当初那般有号召力了.
文化方面中国悠久的历史和文化得到传承,古老的中华文明曾经影响世界相当长的时间,只是到了最近一百多年中国的发展没有跟上世界工业革命的大潮,才导致中国的落后,现在中国的经济重新崛起,使古老的中华文明重新焕发出新的活力.
只要中国保持现在这种务实的思想,中华民族重回世界之颠的时间一定为期不远,几代中华儿女为之抛头颅,洒热血的梦想------振兴中华,必将实现.

人生如戏,那所谓的一场戏只是对个人而言,谁也不会成为谁的主角,只是经过、路过、飘过,像南方的细雨,像北方的沙尘,在特定的季节里完成表演,然后把镜头让给蔚蓝的天空和洁白的云朵.

气流在口腔或咽头受到阻碍而形成的音叫做辅音,又叫子音.（黄）/ 发音时气流受到发音器官的各种阻碍,声带不一定振动,不够清晰响亮的音素叫辅音.（张）/ 气流从肺里出来不一定振动声带,通过口腔时受到一定的阻碍,这种主要依靠阻碍发出的音叫辅音.辅音按发音部位可分为：唇音、双唇音、唇齿音、舌尖音、齿音、卷舌音、齿龈音、齿龈后音、龈颚音、舌面音、硬颚音、唇硬颚音、软颚音、 唇软颚音、小舌音、舌根音、咽音、会厌音、喉音.按发音方法可分为：鼻音、塞音（爆音）、擦音、塞擦音、近音（无擦通音）、闪音（弹音）、颤音.清浊音：辅音发音时声带的振动模式.发浊辅音时,声带有充分振动；发清辅音时,声带完全不振动.VOT(voice onset time)：一辅音从除阻的一刻到声带开始震动,中间所经过的时间.送气与否与VOT有关.气流机制：通过声道的气流的产生机制.在大多数语言中,所有辅音都采取肺呼气机制(pulmonic egressive),但部分语言也会使用紧喉音（喷音）(ejectives)、内爆音(implosives)、搭嘴音（啧音）(clicks)等气流机制不同的辅音.长度：辅音的发音中,阻塞维持的时间.在日语、意大利语、芬兰语等语言中,一般辅音与双辅音(阻塞较长)代表不同的音位.在爱沙尼亚语及少数其他语言中,甚至有三种不同的辅音长度,虽然牵涉其中的发音差异较为复杂.发音时的力道：一个尚未完全确立的特点,因为目前没有观察到任何语言纯綷以力道来区分不同辅音.一般的现行语言有二十到三十个辅音.拉托卡斯语（Ratokas）只有6个辅音p、b、k、g、r、t,是已知语言中最少的.辅音最多的是阿尔瓦语,有四十三个.历史上曾出现的最多辅音是高加索语系的Ubykh语,据说有多达84个辅音音位,同时仅有2个元音.该语言在1992年10月7日宣告消亡.

总有一种角色适合我
薛崇伟
①曾看过这样一个故事：
②静谧的非洲大草原上,夕阳西下.这时,一头狮子在沉思,明天当太阳升起,我要奔跑,以追上跑得最快的羚羊；此时,一只羚羊也在沉思,明天当太阳升起,我要奔跑,以逃脱跑得最快的狮子.
③话说这只狮子发现了一只羚羊,追了半天也没追上.别的动物笑话狮子,狮子说：“我跑不过是为了一顿晚餐,而羚羊跑却是为了一条命,它当然跑得快了.”
④是的,无论你是狮子还是羚羊,当太阳升起的时候,你要做的就是奔跑,尽管有的为晚餐,有的为生命.因为目的从来是没有过失的,错误与罪恶总是出在手段上,犹如猎手只瞄准而不射击,士兵只呐喊而不冲锋.
⑤也许你奔跑了一生,也没有到搭彼岸；也许你奔跑了一生,也没有登上峰顶,但是抵达终点的不一定是勇士,敢失败的未必不是英雄.不必太关心奔跑的结局如何,奔跑了,就问心无愧；奔跑了,就是成功的人生.
⑥人生之路,无需苛求.只要你奔跑,路就会在你脚下延伸,人的生命就会真正创新,智慧就会得以充分发挥.
⑦生活中,那些所谓的成功者总是被善意地夸张着,好像他一生下来就证明了他是一个不平凡的人,而那些曾和你我一样的凡人,却在一遍又一遍地演绎着试图证明自己不是凡人的闹剧.一次又一次地失败之后,凡人终于发现其实自己也不过是一个凡人.正是由于发现了这一点,所有的一切事情的得失就似乎都算不了什么了.一次次相遇的错过,一次次逝去的优越条件,一个个失败……凡人问自己：“这难道就是凡人的悲哀吗?”凡人就是凡人,凡人只有凡心.于是凡人对自己说：“何必沮丧呢?我干吗要庸人自扰地看着别人的角色而懊丧呢?这个世界一定有一种角色是适合我的.”
⑧凡人渐渐发现,凡人也有成功的时候,一个善意的赞扬、一次深深的感动、一种不菲的收获……都意味着凡人的成功."成功"这个字眼儿并不意味着像爱因斯坦那样闻名于世,像爱迪生那样造福人类……凡人终于知道所有的成功并不一定要轰轰烈烈,也并不一定要出人头地,只要你把握自己,好好地活着,别在烦恼中虚度光阴,你就会发现茫茫人海中,你也是不平凡的一个……
⑨人能奔多远?这话不是问双脚而是要问志向；人能跑多快?这事不是问双脚而是要问素质.

Many years ago, one emperor, in order to dress pretty, will not hesitate to spend all his money. He did not care about his troops do not like to go to the theater, he did not like coach逛公园- except to show off his new clothes. Hour each day to change a new set of clothes. It is mentioned that he always said: "The king in the locker room."
One day, his capital to the two swindlers claiming to be woven work that can be woven out of the world's most beautiful cloth. This kind of cloth colors and patterns are not only exceptionally beautiful, and sewing clothes out there is a strange characteristic: Any foolish or incompetent person was hopeless, can not see these clothes.
"That's the best clothes!" Thought the emperor, "I wear such clothes, I can see the kingdom who are not competent; I can identify people who are smart and who is the fool. Yes, I would like to ask them to immediately woven cloth to such! "He paid a lot of cash to the two swindlers and ask them to start work immediately.
They put two loom, pretending to look at work, but they loom in the shadow of something even none. An urgent request that they give some of the most fine gold, raw silk and the best. They have these things into their own pockets, only two air-to-air in the busy looms until late at night.
"I'd like to know how well woven fabrics exactly," said the Emperor would like to. However, think of anything stupid or incompetent person can not see it on the cloth, his heart did not feel natural. He believes that there is no need for fear of his own, but still feel that first sent a person to see the progress of the work more appropriate circumstances. The whole city of people have heard about how this fabric has a magic power, so are we all like to take this opportunity to test this: their neighbors, how stupid, how stupid.
"I want to send an honest old minister to the weavers there," the emperor thought, "he can see what this fabric is, because he is very sensible on this point incompetent, and he who does not."
The good old minister of the two swindlers came to the house and saw the empty loom that they are too busy to work on.
"May God have mercy on me!" The old minister would like, he was particularly large eyes, "I did not see anything!" But he dared not saying that these exports.
The two swindlers requested that he approached at the same time pointing to the two asked him loom overhead pattern is not very beautiful, color is not very pretty. The poor old minister of the more open the eyes bigger, still can not see anything, because nothing really.
"My God!" He thought. "Do not be foolish I am? I have never doubted their own. This must not be aware of this matter. Is it you I was incompetent? Not! I can not make people know that I did not see the cloth."
"Hey, you did not point it?" A crook that is weaving.
"Oh, beautiful! Really beautiful!" Said the old minister of the side of the glasses from his side in a careful look, "What a beautiful pattern! How beautiful colors! Yes, I will be reported to the emperor, I have cloth very satisfied. "
"Ah, we listened very pleased." Liar two said in unison. So they had a rare color and a description of the pattern, but also to add more terms. Old minister listened attentively, in order to return to the emperor could still back out there. In fact, he will do so.
The two swindlers have more money, more silk and gold, said that the need for weaving. They took these things into the pockets of the whole.
But soon enough, the emperor sent another honest officials to see the progress of the work. The official head of the luck is not a minister than good: he看了又看, but the two on the loom overhead with nothing, anything he can not see.
"You look beautiful this cloth?" Asked the two swindlers. They pointed to, to describe a number of beautiful patterns - in fact they do not exist.
"I'm not stupid you!" The official thought, "This is probably there now, I do not deserve it such a good official. This is really funny, but I can not see it!" He did not see him a lot of praise of the cloth, while ensuring that he was the color of these beautiful and clever is very satisfied with the pattern. "Yes, it is really beautiful," he said to go back to the emperor.
Everyone in town talking about the beautiful fabrics.
Emperor will be very interested to see one in person. He selected a group of special delineation of the entourage - including already seen to be honest the two ministers. He would go there two to cunning liar. These two guys are fully the spirit of weaving, but also the shadow of an invisible wire.
"You do not look at this gorgeous gorgeous fabric?" Two honest officials said, "His Majesty see: how the United States and the pattern! How beautiful colors!" They pointed to the loom overhead, they believe others see fabrics.
"This is how all about?" Thought the emperor. "I did not see anything! That the appalling. Should I be a stupid people? Why can I not qualified to do the emperor it? This is the most horrible thing." "Oh, really beautiful!" Said the emperor. "I am very satisfied!"
He expressed satisfaction over his head. He carefully looked at loom like to say he did not want to see nothing. With him to all his entourage also看了又看carefully, but they did not see more than others things. Like them, like the emperor, but also said: "Oh, really beautiful!" They proposed to the emperor in this novel, the beautiful clothes made of cloth, wearing these clothes to take part in the procession at the ceremony is about. "This fabric is gorgeous! Exquisite! The unique!" Echo of everyone. Tell everyone happy. The Emperor gave each a liar, "Royal appointment weaving division" of the title, sealing them to jazz, and can be linked to an award of the Medal in the buttonhole.
The next morning, the procession ceremony will be held. The night of the first day, two swindlers night for more than 16 points from the candle. People can see that night they are in a hurry, it is necessary to the completion of the emperor's new clothes. They pretended to remove from the loom fabric shears with two CD in the air for a while, at the same time with no threading a sewing needle pass. Finally, they said in unison: "See! Good sewing new clothes!"
The emperor himself with a group of the most noble knights come. The two swindlers raised one hand, it seems like anything with a. They said: "Please look at it, this is pants, this is the gown, which is a coat." "It's like a spider's web, like soft clothes, wearing them will feel as if nothing like this is these clothes advantages. "
"Is also pretty good," Knight said all. But they could not see anything, because what does not.
"Now please take off their clothes the emperor," two swindlers said, "so that we in the large mirror in front of you put on new clothes."
Emperor to all his clothes off. Two swindlers pretended to put one by one they have just seam to give him a good new clothes. Them around his waist get there for a while, I think it was a tie on something like: This is after裾(Note: after裾(Slaebet) is dragging behind in a long dress of a piece of cloth; it is feudal an era of aristocratic dress in Europe.).转了转before the emperor himself in the mirror, twisted the扭腰.
"God, how these clothes fit ah! Conference ah how nice!" Everyone says that. "What a beautiful pattern! How beautiful colors! This is really expensive clothes!"
"Everyone is waiting outside, ready for the canopy in order to give His Majesty the head in a ceremony to participate in the procession." Ceremony official said.
"Yes, I have put the." King said, "It All my clothes are you?" So he put himself in the mirror before turning a bit, because he make you see that he carefully watched his beautiful lift.
After those who will be holding in the Hill裾hands are touching the floor East West touch, as if they are picked up after裾like. They started walking, holding the hands of the air - they did not dare make瞧出They really did not see anything.
In this way, the emperor in the procession under the rich canopy up. Standing on the street and people say that the window of the house: "Good! Emperor's New Clothes is beautiful! His shirt after the following裾how beautiful! This dress is really All his!" People who do not want to know what can not see anything because it will show their own incompetence, or too stupid. All the emperor's clothes have never received such praise.
"But he did not wear the clothes my children!" Finally, a child called out loud.
"God, yo, you listen to the voices of the innocent!" Said his father. So we put the children privately whispered words spread.
"He did not what to wear! Have a child that he did not what to wear it!"
"He is not what to wear it!" All the people the final say. Emperor trembled a bit, because he felt that people say they have seems to be true. However, such a mind of his own thinking: "I have to hold this ceremony completed the procession." Therefore, he assumed a more proud of the air, he's in Jackson were walking behind him, holding hands after a dress that does not exist .

Family structure theory suggests that family structure is the division of roles of family members, during which contact with a certain character, and how interaction and organization, interaction and impact of this interaction and impact of the formation of the family model type. According to sociological and anthropological point of view, the main focus of the family structure is the family structure of the basic triangle, the famous sociologist Fei Xiaotong that in a marriage contract which includes not only a relationship, but includes two kinds of associated social relationship - the relationship between his wife and child relationship. These two relations can not separately, husband and wife relationship is the premise of parent-child relationships, parent-child relationship with his wife as a necessary condition for the relationship. This is a trilateral triangle, is not the shortage, and the "DINK" The family is built on the marriage-based, contain only a social relationship, the relationship between husband and wife Jesus, but a simple horizontal family relationships. It is the backbone of the family and the nuclear family as the mainstream in this context of a useful exploration of the family structure and then the formation of a new type of family relationship.
Sino-US differences in family structure, it is clear there are: "DINK" family formation of the reasons. In the United States does not want born Dink, while in China because no raw and Dink.
The family structure is a combination of status of family members, it is inter-generational family structure and population structure of the unified form of combination. West differences in family structure reflects the different Chinese and Western family values.
Genetic relationship between the Chinese people attach importance to China's relations with the blood on behalf of the strong affinity, passing three major characteristics of strong and sustained strong. But in China's modernization process, constrained by the social environment, or promote, our family structure showing a significant change in the following characteristics: (1) family size small: the nuclear family or small families on the rise; (2) Stem Family (referring to a family with more than two generations, each generation is only a couple) is still a considerable proportion; (3) diversity of family types: the core of family-oriented, and other non-core-oriented small families, such as inter-generational family , DINK families, empty-nest families, single-parent families, single-parent families are also being posed by urban and rural family structure important content.
By contrast, Westerners are not as for the genetic relationship between the Chinese people are so great importance. In Western countries, the nuclear family overwhelmingly dominant position, while the backbone of the family negligible, in addition to single-parent families, single-parent families, cohabitation and family forms.
2. The relationship between the individual and the family
Deeply influence of Confucianism, the Chinese people's strong family values. In the individual, family, group three, the family holds a very prominent position. In dealing with the relationship between the individual and the family home will always be sacred, the first one, and personal interests subordinate to the interests of the family (and family interests and family interests are closely linked), and often combined.
In Western cultures, individuals and groups occupy a much more important than the family's position. The family is the basic unit of society, but it can be further broken down into individual. For the Westerner, not only the main body of knowledge, natural domination, but also the masters of society and family in the personal and family relations, personal interests and aspirations of the dominant factor, while the family is of secondary importance

解题思路：（1）生态系统的组成：树等绿色植物能进行光合作用是生产者；虫、鸟等动物不能进行光合作用是消费者；细菌、真菌能将动植物遗体中的有机物分解，分解产生的二氧化碳、水、无机盐又被生产者利用，是分解者．
（2）根据光合作用的定义分析解答．生态系统中能量流动的特点．
（3）生态系统的组成包括非生物部分和生物部分．
（4）食物链是指生产者和消费者之间吃与被吃的关系．

（1）生态系统的组成：树等绿色植物能进行光合作用是生产者；虫、鸟等动物不能进行光合作用是消费者；细菌、真菌能将动植物遗体中的有机物分解，分解产生的二氧化碳、水、无机盐又被生产者利用，是分解者．
（2）绿色植物通过叶绿体利用光能把二氧化碳和水合成有机物，并储存能量，同时释放出氧气的过程叫光合作用．光合作用实现了能量转化，把光能转化为储存在有机物中的能量，因此能量的最终源头太阳光能．
能量流动是指生态系统中能量的输入（通过植物的光合作用把光能转化成化学能）、传递（流入下一营养级，流入分解者）和散失（各生物的呼吸作用散失）的过程．下一营养级的能量来源于上一营养级，各营养级的能量有三个去向：①该生物呼吸作用散失；②流入下一营养级；③流入分解者．营养级越多，能量流动中消耗的能量就越多，所以，营养级越高，储能越少，个体数量越少．因此，在生态系统中，对生物的个体数量起决定作用的是生态系统中的能量；这就决定了：大多数食物链一般只有3-4个营养级．一般地说：输入到下一营养级的能量中，只有10%-20%的能量能流入下一营养级，例如：第一营养级：草，固定的太阳能为1000千焦，则第三营养级最多能获得多少千焦？（40千焦）；由此可以得出：能量的流动是沿食物链逐级递减的，单向不循环．
（3）生态系统的组成包括非生物部分和生物部分．非生物部分有阳光、空气、水、温度、土壤等．
（4）食物链是指生产者和消费者之间吃与被吃的关系，植物被昆虫吃，而昆虫又被鸟吃了．
故答案为：（1）生产者；消费者；消费者；分解者；（2）太阳光能；逐级递减的；单向不循环；（3）非生物；阳光、空气、水、温度、土壤等；（4）植物→虫子→小鸟．

点评：
本题考点： 生态系统的组成及各部分的作用；生态系统中的食物链和食物网；生态系统中物质和能量的流动．

考点点评： 此题关键是理解生态系统的组成，知道生态系统中生物的数量变化以及食物链的知识．

Four main roles
* Sheng (生,Male role)
* Dan (旦,Female role)
* Jing (净,Painted face male role)
* Chou (丑,Clown role)
The three roles other than the second role represent male characters.
There is an explanation about why the roles take the names above.It is said that they were chosen to have opposite meanings.Sheng in Chinese may mean "strange" or "rare",but the chief male role is a well known character.Dan,which means "morning" or "masculine",is contrary to the feminine nature of the characters.Jing means "clean",but in fact the paintings on their faces make the characters look unclean but colorful.And Chou in Chinese sometimes represents the animal "ox",which,in some senses,is slow and silent - in contrast,the Chou characters are usually quick and talkative.

Abstract:the sand monk is the ancient Chinese novel " journey to the west " of the characters,he looks ugly,but the personality honest,bear hardship without complaint,modesty,and Buddhist precepts.Sand monk in " journey to the west " in the text not much,image and no other three lead as outstanding,but he is from the team indispensable figure,he played the role of a foil and harmonic in four.Keywords:Journey to the West; the sand monk; modesty; harmonic function

动物从古到今都是我们人类的朋友.可是现在我们身边的动物却越来越少,但我们还在不停的去猎杀动物,穿动物的皮毛,吃动物的肉.可是我们现在却到处可以看见保护动物的标识.这是为什么呢?所以我们要保护好我们身边的每一个动物.现在我们看见的都是一些有害的动物,有益的动物却越来越少.我是很喜欢可爱的动物但是这些动物却不断的被我们猎杀吃掉.就算我们在多写保护动物的标识可是我们要是没有保护动物的意思写这么多保护动物的标识干什么哪?所以我想只有让我们有保护动物的意思才能真的学会如何的爱护我们身边的动物,所以千万不要让我们人类成为世界上最后一种动物,千万不要.我们应该阻止猎杀这些可怜的动物,相反不要在让哪些可怜动物的皮毛出现在我们的身上,不要再让哪些可怜的动物出现在我们的餐桌上.不要再让电视上在出现某些动物被猎杀,某些动物全球仅剩多少只.我们已经经受不起这样的新闻了.我希望所有的动物都像天上的星星一样数不尽数.动物的濒临灭绝不仅对大自然不好也对生态平衡也是有害处的,所以我们要好好保护我们身边的每一个动物.最重要的是我们要有保护动物的意思.我最大的愿望是我们和动物和睦相处,尤其是动物希望它们可以天天开开心心的.找个安全的地方繁衍生息.朋友们,动物是大自然留给人类起,从我做起,保护动物,使世界变得更美好吧!保护动物,就是保护人类自己!的无价之宝,它是我们人类的朋友.它们的生衍死灭与我们人类的生活是密切相关的.动物的大量毁灭对人类将产生严重的不良后果,造成生态严重不平衡,从而使人类的生存环境遭到破坏.让我们从现在做起.

　　最珍贵的东西
　　我发现了生活周围最珍贵的东西.
　　那天,带着一些不高兴的情绪回到家,迎来的是父母开怀的笑脸,本已为他们听了老师的告状会把我臭骂一顿,可他们却是如此的反常.
　　带着疑惑走进了房间,翻开书包,拿起作业就在书桌前埋头苦干.
　　时间过得真快,不久就到了晚上九点多,可作业去丝毫不见减少,妈妈悄悄地拉开了房门,蹑手蹑脚的进了房间,坐在床前.虽然我在写作业,但仍听着妈妈对我说的话.妈妈说我老大不小了,该懂事了什么都不用妈妈讲明白,但那是我却心里几万个不服气：“要说就说嘛,何必拐歪末角的.”便又投入到作业之中.
　　完成作业已是十一点多,回想起妈妈所说的话越想越气,他怎么这么受我虽没表达清楚但我知道他是在拐着弯说我,想着吧,还真越想越气.何必那么气呢?放松放松,好好迎接明天辛苦,繁忙的一天吧!
　　理好书包,躺在床上翻来覆去睡不着,随手拉亮了床头的那盏明灯,随手拿起了床上那本《读者》,里面写道：“最珍贵的东西是免费的,阳光是免费的,空气是免费的,亲情是免费的,友情是免费的,爱情是免费的……..”有人看见指或许会不削一顾,但想想它们难道不是最珍贵的吗?
　　回想起刚才妈妈并没有把事情讲明,不正是在给我的面子上留有余地,给我爱的鼓励,爱的警戒吗?妈妈给了我最珍贵的东西,而我却只是抱怨.她给与我是免费的,或许以后我就不在会拥有.
　　是啊,它们往往不经意地出现在我们的周围,我们都会忽视它,而真正到了失去的时候才追悔莫及.细心感受周围的一草一木,或许你会感受到不一样的东西.
　　闭上眼睛,用心来体会周围最珍贵的东西,如果你发现在思绪的另一头有阳光,那你才真正体会到了珍贵的所在.
