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.

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。

人的爱好多种多样，有新奇绝妙的，有平淡无奇。我的爱好虽不新奇，但广泛得连父母都时常感叹。而在这众多的爱好之中，我还是对读书情有独钟。

爱看书还得从七年前说起。那是贪玩的我并不怎么爱看书，但有一次，从玩具堆中发现了一本被翻开的书。好奇心促使我看了下去。一下子，我马上被书中那精美的插图与那精彩的内容给吸引了。而且一发不可收拾，从此，我就爱上了读书。

长大后，懂事的我越来越爱看书了，每天都要看，少看一天都不行，成了一个不折不扣的“小书虫″。为此，我还闹出了笑话呢!记得有一次，妈妈让我烧水，烧水时，我便拿起一本书，津津有味地品读书中的精彩内容，看得忘乎所以。结果，水壶被烧坏了，搞得满屋子烟。这时，妈妈看见了，就问我怎么回事。我这时才回过神来。“糟糕!我的水呢?”妈妈见我这副模样，无可奈何地唉声叹气：唉!你这个小书虫!我提醒过你多少次了……’’

虽然我因为看书误了事,但我仍然爱读书.因为从书中,我学会了许多知识,悟出了许多道理,认识许多朋友：丑小鸭、快乐王子、孙悟空、鲁迅、冰心、爱迪生……读书还使我的作文水平提高了不少呢!

现在,书成了我每天必需的营养品,生活中没有书,就好像鸟儿没有翅膀，生命没有书,就好像生活没有阳光,书是人类进步的阶梯，书是知识的源泉!

我爱读书,因为读书使我的生活丰富多彩，使我的生命充满阳光!

Have you ever wondered about theStars? In some ways， stars are like people. They are born， then grow old， and at last they die.

A star is born from dust and gas. Slowly the dust and gas make a ball. The ball gets very hot. Then it stars to give off light.

The young star grows into a giant. Many years go by. The older star begin to get small again. At last its light goes out. The stars life is over.

刚开学，我们班上就来了个新的英语老师——熊老师。

熊老师瘦瘦的，鼻子上还架着一副白色的眼镜，黝黑的长发上有一个发卡。

第一天，熊老师刚走进教室，闹哄哄的教室立刻安静了下来，大家都目不转睛地望向这位新的英语老师。刚开始，熊老师的声音很小，几乎第一排的同学都听不见，好在熊老师有扩音器。看来熊老师还 有点“胆小”。

熊老师对我们的要求很高，要我们每个人听得懂、读得来，考试要考好。另外，熊老师还在班上分了小组，让每个小组比赛，来培养兴趣。结果，大家通过比赛都提高了成绩，有了学习英语的兴趣，看 来熊老师真有办法，我们慢慢喜欢熊老师了。

熊老师，她真好！

I have a new classmate.She is Huang Jie.She is girl.She is twelve years old.She has long hair.She has big eyes and small nose.She is tall.My classmate likes reading book,playing computer games,listening to music,but sometimes she likes playing sports.

This is my classmate,What about you.

Nature, the environment which human beings live by, is magnificent and unique. There si only one earth with super living conditions in the universe. We should have cherished nature and preserved it. Conversely, however, we have been continually spoiling it, even to a shocking degree. Now lets see what we have dong.

Thousands of trees have been cut down per year, which has caused soil erosion. Hundreds of thousands of tons of CFCS have been left in the higher sky in the last decade which has led to the ozone layer leak above the South Pole that covers an area of that of the United States. Million tons of fuel containing nitrogen and sulphur have been consumed per year, which has eventually resulted in acid rain throughout the world.

Similarly, ecology has been affected as well. And considerable number of species have been extinct as the years go by many creatures which were common in the past are becoming less and less, even rare. The Tibet antelope, for instance, is a good example. Since the antelopes of Tibet have a part of fur on their body which can be made into a precious cape, driven by some lawless dealers many villagers killed antelopes excessively and shocking for the large suns of fortune. Because of this, the number of the antelopes of Tibet has sharply fallen from over one million to less than one hundred thousand. And whats more, the number has now decreased by 20 thousand per year. Qing Zang Platean, which was their homeland, is their tombs now.

This is how nature has suffered what we have done to it. However, nature and suffer any more. She lost her temper and could no longer possibly put up with humans. She gave humans harsh punishment, which she thought they deserved. The acid rain has caused the less of more than 100 billion dollars throughout the world per year. And because of desertification , soil is becoming more and more barren. The soil of many planes is now until for growing plants. The air is less fresh, and a lot of people even get many stranger diseases. Those are all the punishment of nature to humans pollution. On the other hand, human being suffer a lot as well.

So it leads to a serious of questions--

Why cant we live harmoniously with nature?

Why cant we set a balance between human and nature?

Why cant we pay more attention to nature and try to reserve it?

Therefore, before we take immediate measures to do something, we should be aware of the fact that "Conquering the nature" will never be our goal, instead, we should take the nature as our intimate friend. Preserving nature is not only preserving our home, but the civilization of human community as well.

自然,人类生活的环境,是宏伟的和独特的。si只有一个地球和宇宙中超级生活条件。我们应该珍惜自然,保护它。相反,然而,我们一直在不断地破坏它,甚至令人震惊的程度。现在让我们看看我们有盾。

每年成千上万的树木被砍伐,造成了水土流失。成千上万吨的氯氟烃已经在更高的天空在过去十年里导致南极上方的臭氧层漏洞,美国的占地面积。几百万吨含氮和硫的燃料消耗,这最终导致全世界酸雨。

同样,生态也受到影响。和相当数量的物种已经灭绝,随着年龄的增加许多生物这在过去是很常见的正变得越来越少,甚至罕见。例如,西藏羚羊就是一个很好的例子。自西藏的羚羊有毛皮在他们身体的一部分,可以做成一个珍贵的披肩,由一些不法经销商许多村民杀羚羊过度和令人震惊的大太阳的财富。正因为如此,西藏的羚羊的数量已经从一百万降至不到十万。,更重要的是,现在每年减少了2万。清代藏高地,这是他们的家园,现在他们的坟墓。

这就是大自然遭受了我们所做的。然而,自然和痛苦。她失去了她的脾气,不再能忍受人类。她给了人类严厉的惩罚,她认为他们应得的。酸雨造成的少每年全世界超过1000亿美元。正因为沙漠化,土壤变得越来越贫瘠。现在许多飞机的土壤,直到种植植物。空气不新鲜,很多人甚至许多陌生的疾病。这些都是自然对人类的惩罚污染。另一方面,人类遭受了很多。

所以它会导致一个严重的问题—

为什么我们不能与自然和谐生活吗?

为什么我们不能建立人与自然之间的平衡?

为什么我们不能更加关注自然和试图储备吗?

因此,我们立即采取措施做某事之前,我们应该意识到这样的事实:“征服自然”永远是我们的目标,相反,我们应该以自然为我们亲密的朋友。保护自然不仅是保护我们的家园,但人类社会的文明。

烟里有一种对人身体不好的东西——尼古丁。

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。

香烟是隐藏在我们身边的隐形杀手，是大家所应警惕的。

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。

烟对人的危害是多么大啊!所以我们不能吸烟。杜绝吸烟，造福后人。
