A good book not only brings happiness to people, but also comforts; it can

not only make you think deeply, but also enlighten you. A good book is a wise

man, a mentor, a friend, and a partner. My favorite thing is reading.

books also bring me much joy. I remember one time, my mother bought me

"Insects", the book records many insects and their habits. I couldnt put it

down, and when I got home, I picked up the book and read it with interest. When

I read the firefly insect, a beautiful scene immediately appeared in my mind: On

a summer night, I was walking in the park, and at this time, many fireflies were

flying around me. Illuminate the way forward... The more I think about it, the

more excited I am, and I read it more seriously. When I read about ants, an

insect, I couldnt help but be shocked by its unity. Together, ants can move

things that are several times heavier than them. I also feel that we must learn

from the spirit of ants. Reading and reading, I forgot the time. It wasnt until

my mother came to ask me to eat, I reluctantly put down the book and swallowed a

spit, as if swallowing wisdom into my stomach, my heart was still in the

colorful world of insects.

Gorky once said: "I am on books, like hungry people are on bread." Food

feeds only our bodies, and books feed our souls. Books can increase our

knowledge, broaden our horizons, and improve our writing skills; they can bring

us inspiration and happiness. "When the book is used, we hate less", so I think

we need to read more and read more books to make our achievements bloom like

sesame seeds.

一枝香烟中的尼古丁可以毒死一只小白鼠,25g的香烟里的尼古丁可 毒死几头牛,40至60毫克纯尼古丁可以毒死一个人。

尼古丁的危害也是相当的大,它可以引起胃痛或其它胃病;还会使人引起心律不正诱发心脏病;严重的还可能引起癌症的爆发。

据科学家测定,烟草中含有数百种复杂的化学成分,大部分对人体有害,其中焦油、尼古丁、酚类、醇类、酸类、醛类等40种是有毒和有致癌作用的物质。烟在点燃后,所产生的烟雾,包含了烟草中所有的化学成分,同时比烟草本身又增加了一些有害物质,如一氧化碳和烟焦油等。这是因为除烟草本身外,在制成卷烟的过程中,要在原料中加入一些可可、甘草、糖、甘油、乙二醇等调味、湿润、产香、助燃物质。这些添加剂虽然本身无害,但在燃烧过程中却起了变化。例如,在鼠背涂上可可燃烧后产生的烟油,可长出皮肤瘤。甘草中的甘草酸在燃烧后,与其他成分化合,可生成有致癌作用的多环芳烃。糖与烟草一起燃烧后增加了焦油量,而糖燃烧后的产物是烟中的一个重要致癌物。甘油和乙二醇在燃烧后的物质,不但可能使吸烟者患膀胱癌,而且所产生的丙烯醛可抑制气管和纤毛分泌物从肺内排出,从而增加患气管炎和肺气肿的机会,并使患有这两种病的人病情加重。

Human, science and nature, the three phase was quoted rates are inseparable. The wonders of nature, a little thing, through the baptism of the time, and meticulous observation, often can give a person with enlightenment.

Vast forests, sunshine give plants grace, to be able to get the nutrients and thrive. Such as the morning sun open the eyes of animals, everything is ready. Squirrels, squirrel, embarks from the house, looking for full sweet red pine nuts, all kinds of plant seeds and slowly by seeding them to other places. While the weasel feed on smaller herbivores, sable and then ate the weasel... As if people eat the big fish, big fish eat small fish, small fish eat shrimp, shrimp eat plankton, interlocking between RACES, interdependence restricts each other.

Foreign scientists have done an experiment: introduce the sheep in a rare nature reserve, where the bamiyan, natural environment is superior, and there is special personnel to the group of kids to their natural enemies, Wolf, moved to another place. So the sheep started in the breeding. Until grass and low shrubs are eaten, the number of sheep instead of less. Because they live too comfortable, there is no enemy attack, the number that is too carefree life let their constitution also fell. Then the scientists tried to introduce wolves again. The result is in the relationship between predator and prey, good robust species to survive, wolves eat sick defect part. Natural selection and evolution, has been the nature and even the survival of human society the same criteria.

Cut down some trees, is to destroy a part of birds and insects; Killing of bees, small fish, can also cause cannot spread pollen, fish cannot reproduce problem... Sabotaged a part of the food chain, will bring ill-defined disaster. Because in front of the natural fair, each species, each independent individual organisms is so beautiful and full of value.

Because of the diversity of species and colorful nature. Want to live in harmony with her and get the kind of treatment, will be good to nature, to understand the nature, and have good at discovering and innovative mind.

人类、科学、自然,这三者相生相息密不可分。大自然的奇妙之处在于:一件小小的事物,经过时间的洗礼以及细致入微的观察,往往能给人以启示。

广袤的森林中,阳光雨露给予植物恩泽,使其能够得到养料然后茁壮成长。等清晨的阳光掀开动物们的眼睛,一切也准备好了。松鼠、灰鼠从居所里出发,寻找饱满香甜的红松子,各种植物的种子于是慢慢的被他们带到其他的地方落地生根。而此时黄鼠狼以体型较小的草食动物为食,紫貂继而吃掉了黄鼠狼……就好像人吃大鱼,大鱼吃小鱼,小鱼吃虾米,虾米又吃浮游生物一样,各种族之间环环相扣,相互依存相互制约着。

外国的科学家曾做过一个实验:将一种稀有的羊引进自然保护区,那里水草丰美,自然环境优越,并且还有专门的人员为这群天之骄子将她们的天敌——狼,迁往另外的地方。于是羊群开始在此生息繁衍。直到草和低矮的灌木被吃光了,羊群的数量反而越来越少。原来是因为它们生活的太过安逸,没有天敌进犯,数量过于膨胀,太过悠闲的生活让它们的体质也下降了。后来科学家们尝试着再一次引进狼群。结果是在捕食者与猎物的关系中,健壮优良的品种得以存活,狼群则吃掉病弱残疾的部分。物竞天择,优胜劣汰,一直都是自然界乃至人类社会不变的生存准则。

砍掉了某种树林,就等于灭绝了一部分鸟类、昆虫;捕杀蜜蜂、幼小鱼类,也会造成花粉无法传播,鱼群无法繁衍的问题……大肆破坏生物链中的某一环,都会带来难以言说的灾难。因为在公平的自然面前,每个物种,每个独立的生物个体都是如此的美丽而富有价值。

大自然因为物种的多样性而五彩缤纷。想要与她和谐相处并得到其慈祥的对待,就要善待自然,了解自然,并拥有一刻善于发现与创新的心。

The so-called food safety, is the food does not contain any harmful substances to human body. If food spoilage or containing toxic substances, will bring harm to our body and even life-threatening. Food safety is about peoples life and health. Inferior food greatly endanger peoples health, light diarrhea diarrhea, or poisoning coma, moreover may cause death. Indeed, food safety is directly related with the health and quality of life of the masses. Schools around there are many small shops, the inviting "gourmet" from the fragrance, the classmates to withstand the snack temptation, you, me one yuan to buy a lot of snacks, the results some buy snacks classmates because bought not health food and have loose bowels.

Remember once I saw a news on TV: a famous yogurt brand for some reason, the expired yogurt repackage again, also good food quality supervision administration found in time, otherwise the consequence is unimaginable. Look at these factories, how hard, in order to market competition, regardless of the health of consumers.

The above examples are enough to prove that the importance of food safety, food unsafe events caused great influence to peoples life, food regulators have also been attaches great importance to this problem. Believe that relevant departments can seriously, strict management, give you a rest assured food environment. We, as a primary school student, as a member of a society, we should also be constantly improve the self-protection ability and the ego to protect consciousness, render and do our work with regulators.

在人的生活当中,衣食住行,样样缺不得。特别是食品,它是与我们每个人紧密相连的,是我们每天的必需品。俗话说得好,民以食为天,一顿不吃饿得慌。所以我们更该关注食品安全。 食品安全是我们生活中日益关心的话题之一,工商部门积极管理的同时,也常常实施着食品检查的工作。

所谓食品安全,就是食品里不含任何对人体有害物质。如果食品变质或者含有毒物质,就会给我们身体带来危害甚至危及生命。食品安全关乎人的生命健康。劣质食品极大得危害了人的健康,轻则拉肚子腹泻,重则中毒昏迷,更有甚者可能会引起死亡。的确,食品安全直接关系着群众的身体健康和生活质量。学校周边有许多小店,那诱人的“美食“发出阵阵香味,同学们抵挡不住零食的诱惑,你五角,我一元地买了许多零食,结果有些买零食的同学都因为买了不卫生的食品而拉肚子。

记得有一次我在电视里看到了一个新闻:某一知名酸奶品牌因为某种原因,把过期的酸奶重新包装了一遍,还好食品质量监督管理局及时发现,不然后果不堪设想。看看这些厂家,多么毒辣,为了市场上的竞争,竟不顾消费者的健康。

以上事例都足以证明食品安全的重要性,食品不安全的事件给人们的生活造成了很大的影响,食品监管部门也一直很重视这个问题。相信有关部门能够严肃处理,严格管理,给大家一个放心的食品食用环境。而我们作为一名小学生,作为社会的一份子,我们也应该要不断提高自我保护能力和自我保护意识,以及尽自己的绵薄之力配合监管部门工作。
