今天一早,我在从窗户往外看,外面就像笼罩在大雾中,看不见蓝天、白云、汽车和行人了,就连对面的楼房也朦朦胧胧的看不清,整个城市就像处在仙境中一样。

最近冬天,出现雾霾的次数越来越频繁了。雾霾是雾中悬浮着大量的烟、灰尘等微粒而形成的浑浊现象,使空气质量严重污染,是自然和人为污染环境所形成的。雾霾来源于汽车排放的尾气;电厂、化工厂排出的煤烟和灰尘;燃放烟花爆竹产生的烟雾……这些都是产生雾霾的原因。

雾霾对我们的生活造成的影响是:让我们不能出门;不能呼吸新鲜空气;更不能进行活动;不能上课;容易产生呼吸疾病……但是对我有一个好处是:我有一个弟弟,因为有雾霾,所以他的幼儿园也停课了,我们俩就能在家里一起玩了。那就不会像我一个人在家那么地无聊了,哈哈哈……

雾霾对我们的生活和健康已经造成了很严重的危害,所以我们只有采取各种措施尽量避免雾霾带来的危害:减少外出,抵抗力低的老人和儿童还有患有呼吸系统疾病的人尽量不出门,如果要外出,要佩戴防雾霾口罩。减少户外锻炼;关闭门窗;在家要多喝水、牛奶,饮食清淡,避免劳累。

雾霾对我们的影响很大,所以我们就要想办法减少雾霾。为了减少空气污染,提高空气质量,减少雾霾,那么我们就用实际行动倡导绿色环保理念:少开车,多步行,多坐公交,绿色出行;节约用电;劝亲朋好友少吸烟,不吸烟;春节少放甚至不放鞭炮;多种树,保护森林,改善环境。治霾,从我做起!

我相信,只要大家行动起来,保护环境,保护我们的家园,我们的家园就能变得树更绿、花更红、小鸟的歌声更动听,我们的家园将会更美好!

st important role in the environmental protection today.

In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves.

It gradually turns cool. The sunlight is no longer so strong and the

cicadas have stopped crying. The hot summer went by at last. The favorite season

in the year is coming.

Everywhere we can see the scene of bumper crops: on the fields is golden

rice,on the trees are ripe fruits. The farmers faces are full of smiles. They

are now expecting a good harvest through a summers hard work.

The autumn evening is especially beautiful. When the setting sun goes

slowly down to the west, the sky over the mountains is covered with red rays of

evening sunlight, which shines upon the blue sky and floating clouds, just as

the maple leaves fall onto the sky.

It is getting cool at dusk. The wind blows, the moonlight shines on the

ground,the frogs croak and insects chirp in the fields. Such a situation will

make you forget all the unhappy things in the daytime.

I love the beautiful season.

我们一直提倡要保护环境,可嘴上说简单,又有哪些人在实际行动中做到了呢?地上不还是到处都是垃圾吗?雾霾不还是存在吗?树木不还是被大肆砍伐吗?保护环境可没有想象中的这么容易。 盛夏的阳光真像蘸了辣椒水,坦荡荡的街上没有一块阴凉地。走在路上,迎面的风似热浪扑来。

夏日炎炎,小鸟不知躲藏到什么地方去了;草木都低垂着头;小狗热得吐出舌头不停地喘气。在这样骄阳似火的天气里,可怜的我还抱着个又大又圆的西瓜,累得口干舌燥,恨不得瘫倒在地上,喝上一大桶水。我拿出一张餐巾纸擦擦大汗淋漓的脸,正想往地上一扔走人,忽然想起老师的教诲:保护环境,人人有责。现在因为人类不爱护环境,造成水土流失,破坏自然和生态环境,还减少了氧气,让二氧化碳极度增加!我打消了那个念头,咬咬牙,把餐巾纸捏在手里,重新挺起绿色“大肚子”。

刚开始还能忍受,没过多久,就受不了了。尽管只是张小小的餐巾纸,但太阳光线灼人,小路烤得发烫,脚踏下去一步一串白烟,手里的餐巾纸都热出水了,更别提手,那叫一个难受啊!

不仅如此,西瓜重达12斤,餐巾纸握在手里也不方便拎啊。我迫切地想要扔掉餐巾纸,但理智战胜了冲动。小玮,保护环境是每个人民的职责,你可不能这么轻易就放弃啊!坚持就是胜利,加油!我暗暗为自己鼓劲。我艰难地挪动着,汗水顺着脸颊流淌。一路上我四处张望,希望发现一个垃圾桶,可惜,连垃圾桶的影子都没看见。真是的,这路上好歹也得装个垃圾桶啊,不然人家在外怎么扔垃圾呢!我愤愤地想。没办法,只能靠自己了。就这样,我凭着坚强的毅力,挪回了家。 一回家,我扔了餐巾纸就倒在地上,吹着凉爽的空调,连水都没力气喝了。虽然又热又累又渴,差点中暑,但我心里还是很开心的,因为那张餐巾纸,体现了我保护环境的精神。我终于当了一次“地球环保小卫士”!

动物是上天给我们的礼物,我们应该去好好地保护它。我很喜欢小动画,特别是小鸟,我总是希望自己能像小鸟一样在天上飞翔。

我家楼下后面有一个林子。那里一年四季绿草如茵、树木繁茂。那里不仅是我们的乐园,还是鸟儿的天堂。

在老师与家长的教育下,我们爱鸟的意识特别强,掏鸟蛋、抓小鸟的坏事是从未发生过。鸟儿也似乎明白了我们的善意,胆子越来越大,叫声越来越亮。这里的树这里的鸟,为我们的生活编织了一道美丽的风景线。

一天放学,我突然发现林子里停着两辆摩托车,几个流里流气的男人拿着气 枪在打鸟。一只只鸟儿从树枝上掉下来,像一块块石头狠狠地砸在我心上。我跑到家叫爸爸去制止他们,爸爸却说:我们惹不起。不一会儿,这些男青年满载而去了。

第二天,他们好像发现了金矿似的,天刚亮就来到林子打鸟。一声声的枪响,使我心如刀绞,我知道如果不马上制止他们,他们非要把林子里的鸟杀绝不可。我心急如焚地敲响了二楼工会主席王伯伯的门,王婆伯伯听了我的诉说,安慰我说:我会向上级汇报的。听了王伯伯的话我很失望。一个个经过林子的阿姨叔叔都摇头叹息,但是无一前去制止他们。我伤心极了,这时,一股勇气猛地涌上我的心头,我大步向前大声喊道:不许开枪!他们先是一愣,继而哈哈大笑。一个留长发的男青年正把枪架在树枝上向鸟儿瞄准。我奋不顾身地跑上去把枪管压下来。他立刻凶相毕露,恶狠狠地把我给推倒了,我的头撞到地上流了血,我便哭了起来,哭声引来了许多人,大家纷纷指责他们。

这时,两个保安人员出现了。保安人员先察看了我的伤情,然后为我包扎伤口,并且没收了他们的气 枪,狠狠地批评了他们一顿,还表扬了我不怕邪恶,有正气,环保意识强。我为环保做了一件好事,心里比喝了蜜还甜。

环境保护雅思英语作文怎么写呢?相信很多同学想知道。以下是小编为大家整理分享的环境保护雅思英语作文,欢迎阅读参考。

环境保护雅思英语作文

You should spend about 40 minutes on this task.Write about the following topic:

The earth is being filled with waste material such as plastic bags and other rubbish. Is this really happening? What are some solutions to this problem?

Gives reasons for your answer and include any relevant examples from your own knowledge or experience.Write at least 250 words.

model answer:

Over the past few decades, the increasing amount of industrial wastes and household garbage has become a major problem in many countries. People have questioned what caused this problem and what can be done to improve the situation. In my opinion, two of the most critical causes of this waste material problem are the increased consumption and a shortage of space for landfill.

To begin with, modern lifestyle has contributed greatly to the increasing amount of waste and garbage we produce everyday. In other words, we have turned into a materialistic and mass-consumption society where we use more and throw away more than ever before. Moreover, countries are running out of space to store garbage and waste material. In fact, securing land for waste disposal raises controversies in many countries.

To solve this intractable problem, every citizen needs to participate in producing less garbage. For example, we can bring our own personal shopping bags instead of using plastic bags provided by stores and shops. Besides, the government can enforce stricter laws on companies to use biodegradable packaging or use recycled material. Indeed, this alone can eliminate much of the waste which is sent to at land fills. Companies can also contribute by developing new raw material which is recyclable and will ultimately lead to less garbage. One good example of this is that tire companies develop new tires for cars which are not made of rubber but of new biodegradable material.

As discussed above, individuals, business and the government can share the responsibility to reduce the amount of waste material and to save the earth. I hope that in the future our offspring will be better off with the well-preserved environment.

环境保护雅思英语作文

Environmental hazards are often too great for particular countries or individuals to tackle. We have arrived at a point in time where the only way to lessen environmental problems is at an international level.

Environmental problems have reached such proportions that people feel international organizations must be set up to intervene in world affairs to resolve these problems. Whether this will resolve the problem is very unlikely as international organizations are just an extension of human behavior. That is, if human conflicts cannot be resolved at home, then they are unlikely to be resolved at the international level. Nevertheless, international organizations do attract attention to the growing problem of aims of the international community to resolve the issue of environmental pollution and support their cause, I do not believe it is the best or only way to protect the environment; in fact, it is only a small part of what is needed in a global initiative.

All world problems, whether it is environmental pollution, war, energy insufficiency, or famine, arise from the abusive behavior of all individuals. Therefore, the solution to all these problems is the need for a collective consciousness. What is meant by this is that each individual must be aware of the impact he or she has on the world and their unique part to play in this world. After all, if one is happy with his life, he will surely not endeavor to harm the environment or anyone else. His behavior will be that of a responsible individual.

What is needed, therefore, is education. Education is the key to all problems and it starts from pregnancy all the way to adulthood and beyond. Furthermore, education means that children all over the world should be allowed to go to schools with good teachers and where teaching materials and methods can be adapted to each individual. Education means raising children to be responsible individuals.

This may sound like utopia, but it is not: if a country had important problems in its educational system, then it should realize that it is contributing to the worlds problems. These are perhaps long term solutions, but they are more realistic solutions than setting up yet another international organization.

篇7:有关电脑的小学英语

全文共 1400 字

+ 加入清单

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.

仍然有很多环保问题在近几年。最严重的问题之一是空气,水和土壤的严重污染。污染的空气严重损害人们的健康。污染的水引起的疾病和死亡。更重要的是,植被已大大减少,随着现代城市的快速增长。

为了保护环境,许多国家的政府都做了很多工作。介绍了立法措施控制空气污染,保护森林资源和海洋资源,制止任何环境污染。因此,各国政府正在发挥环保今天最重要的作用。

我认为,为了保护环境,政府必须采取更具体的措施。首先,政府应该让人民充分认识到环境保护的重要性,通过教育。第二,更应努力把人口规划实施的政策,因为更多的人意味着更多的人意味着更多的污染。最后,那些故意破坏谁应该受到严厉惩罚的环境。我们应该让他们知道,破坏环境就是毁灭人类自己。

There are many diseases that are harmful to human health and even threaten human life. Human into the 21st century, the world has occurred in the number of amazing changes. 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.

放暑假了,妈妈带我去龙江参加英语生日会。

我们到了那里,我看到许许多多的小朋友在看动画片呢。这是,老师来了,给我们唱起来生日歌,我们非常开心。接着老师让我们做一个游戏。老师说:‘’让一个女生,一个男生上去。2人把双手高高举起,然后剩下的同学 手拉手在一起钻山洞,谁被捉住了就要换人。“游戏开始了,我们就都跑了起来。老师说:”STOP。“我被捉住了,我换人了,我后面的杨飞翼也被捉住了。

下面老师给我们发了一顶小帽子,小洋烛灯,还拿来三层的蛋糕,老师让我们手拉手,许一个心愿。开始吃蛋糕了,我们非常兴奋,坐在我旁边的小朋友吃的满脸都是。笑的我们乐开了嘴。

要是下次还能来参加生日会,那该多好呀!
