China has many traditional festivals among the year. But I like Mid-Autumn Festival the most. It means harvest, because it is celebrated in the harvest season. And it is the time for famers to express their thanks for harvest. In addtion, it’s the day for reunion. Some people call it Tuanyuanjie. The people work or study far away from home will come back to get-together with their families. They will eat a big meal and mooncake at that time. I hate parting but love reunion. So Mid-Autumn Day is my favorite festival.

一年之中中国有很多传统节日。我最喜欢的是中秋节。那意味着收获,因为它是在收获的季节里面庆祝的。那也是让农民们感激收获的时候。 此外,它也是团圆的日子。有人把它称为团圆节。在远方工作或学习的人都会回来与家人团聚。他们会在那个时候一起吃一顿丰盛的晚餐和月饼。我讨厌离别,喜欢团圆。所以我最喜欢的节日是中秋节。

广大群众:

大家好!

你们还记得我们人类生活的一样必需品吗?没错,这个东西就是动物和植物,就是除了人类以外的生物。

羊、牛、兔、蚕……为我们提供身上的衣服和脚上的鞋子;猪、鸡、鱼……为我们提供了维持体力的食物;大树为我们挡开自然灾害,为我们净化空气;绿草红花装饰了我们的家园。

可是,现在有很多人在破坏它们。有一些人给竹林撒农药,破坏植物的多样性;有些人到处捕杀动物;有些人砍伐树林……

因此,我提出以下几点倡议:

1、保护植物不破坏。

2、保护动物不捕杀。

3、保护自然环境不破坏。

4、少用农药。

5、污水在经过净化才能排放。

人类是生物大家族的一员,我们理应平等对待家族中的每个成员。大家一起行动吧!

Computers are affordable for almost all people nowadays. As a result, an

increasing number of college students take computers to their dormitory to

browse website, watch movies and play video games and so on. This phenomenon has

caused lots of public concern. Some people believe that computer does bad to

students’ health for college students spend more than five hours staring at

computer without break every day. However, for other people, they are positive

to students’ owing computers because students can search for the newest

information. Standing on my point, I’m more tending to the first opinion.

Reasons are as the following:

Firstly, computers will transfer students’ attention. If students take

computers on campus, they would spend much time on computer than on study. For

instance, lots of my classmates usually play computer for amusement once class

is dismissed instead of going to the library to read more books to enlarge their

knowledge circle.

Secondly, students spend lots of time on computers which hurts their

health. It is quite often seen that students stay in dormitory for almost a

whole day without any breaks playing computers. It is all known that computers

have radiation which hurts eyes and skin.

To be honest, students can use computer to search for the updated

information that they want. But for the reasons above, I firmly believe that

students shouldn’t bring computers to college.

亲爱的人类朋友:

你们好!

我是一只在被在类弄混浊的小河里生活的小鱼。自从我出生以来,清澈见底的小河就是我快乐的的乐园。我和我的好朋友在小河里玩,有时还有小鸟来陪我玩。可是好景不长呀。一天,我和朋友在玩耍,我却一天撞在了一堆垃圾上。我的朋友都被臭死了,我赶快游回了家,这样我才躲过了一劫。

我在家门口,看着灰暗的天空,不由的想起了以前快活的日子,我越想越伤心,不由得哭了起来。

我的同伴们渐渐消失,我想:人类呀!人类,地球不是我们共同的家园吗?我们不是应该一起保护她吗?而不是去破坏她呀,对吗?

一天早晨,我起来看见天空格外的蓝,还有许多小朋友在拾河里的垃圾,小河又变得清澈见底了,我看到这一幕就开心地笑了,我以前欢快的日子又来到了,我又开心地玩了起来。

我真心希望我们的地球能永远美好!

In the people for the rapid development of science and technology, but also experienced a better anxiety and even disaster. In addition to the panic of the development of high-tech, especially biotechnology, war and disease seem to bring mankind directly to the door of hell.

Water pollution on the human body harm, the body in the process of metabolism, with drinking water and food, the water of various elements through the digestive tract into the various parts of the body. When the lack of water in some of the human life process necessary elements, will affect human health. For example, in some areas of water iodine deficiency, long-term consumption of this water, it will lead to "big neck disease", is the medicine called "endemic goiter." When the water contains harmful substances, the greater harm to the human body. Carcinogenic substances can be consumed by eating contaminated food (food, vegetables, fish, etc.), into the human body, but also through the water into the human body. According to the survey, drinking contaminated water, suffering from liver cancer and gastric cancer and other cancer incidence, than drinking clean water is about 61,5% higher. When the sewage contains mercury, cadmium and other elements into rivers and lakes, the aquatic plants put mercury, cadmium and other elements to absorb and enrich them, fish eat aquatic plants, and in its body to further enrichment, people eat poisonous Fish, mercury, cadmium and other elements in the human body enrichment, so that the human body and death. In this way, from the aquatic plants → aquatic small animals → small fish → big fish → the body, forming a food chain. The body eventually became mercury, cadmium and other elements of the "foothold."

Water pollution hazards to aquatic organisms Water lives in a variety of aquatic animals and plants. Biological and water, between biological and biological complex material and energy exchange, from the number to maintain a dynamic balance. But under the influence of human activities, this balance has been destroyed. Some of the beneficial aquatic organisms are poisoned when humans release pollutants into the water, and some of the stained aquatic organisms will multiply, consume a lot of oxygen dissolved in the water, so that the beneficial aquatic life is forced to relocate due to hypoxia Or death. In particular, some toxic elements, both difficult to dissolve in water and easy accumulation in the body, causing great harm to humans. Such as mercury in the water content is very low, but the content of aquatic organisms is very high, the content in the fish is also surprisingly high. Assuming that the concentration of mercury in the water body is 1, the concentration of mercury in the aquatic organisms is about 700, and the concentration of mercury in the fish is as high as 860. Thus, when the water is contaminated, on the one hand led to biological and water, biological and biological balance between the damage, on the other hand some of the toxic substances continue to transfer and enrichment, and ultimately endanger human health and life.

每个月的15号,爸爸都会带上我回老家。 On the 15th of each month, my dad will bring me back to my hometown.

爸爸说有两个原因,一是回来看望奶奶,二是给村上的池塘清清垃圾洗洗……

我心里觉得很奇怪,为什么池塘也要洗澡呢?爸爸告诉我:“如果你十天半月不洗澡会怎么样呢?身体臭臭对不对?那池塘也是一样,那么多的垃圾被扔到里面,也会臭臭哦,那么池塘里的小鱼和其他小动物也会被污染的,我们也就吃不到干净的小鱼小虾,不能用干净的水洗米洗菜,也不能下池塘游泳了哦。“

我问爸爸为什么其他那么多人不去干活,为什么要你去捡垃圾呢?爸爸说他是党员,要起带头作用,要让更多的人知道水资源的珍贵,让更多人知道保护水源的意义。于是,我帮着爸爸一起捡起池塘边各种大大小小的垃圾,心里觉得很开心。

就这样捡着捡着,突然间想起不久前妈妈带着我到施光南玩,看着那广场上弯弯曲曲的小河流水,我感到很开心很兴奋,狂奔着跑向小河,挽起裤管刚想下去玩水游泳,结果被妈妈阻止了,但还是嘟着嘴坚持要下去,想着那就是我的天堂,妈妈真不够意思。这时妈妈走过来,摸摸我的头,微笑着说:”宝贝,那小河里被扔进了很多的垃圾,会产生很多的细菌,你要是下去玩水,身上也会粘满细菌,对身体不好哦,要不我们先一起把小河里的垃圾捡起,等下再去买把水枪喷射好了,告诉正在扔垃圾的其他人不可以这样做好吗?“

虽然觉得妈妈的话很有道理,虽然玩水枪一样玩得很开心,但是心里觉得还是有点遗憾,我是多么想下去玩玩水,游游泳啊!

多么希望每个人都能够讲卫生,不往水里扔垃圾,多么希望明年的今天回到这里时可以看到清爽干净的水,可以不再只是玩水枪,而是可以下水玩个够啊!
