Recently, we often show that shopping online is better than in store, but

is this really the case? Actually, there is no consensus of opinions among

people as to the view of shopping online is better than traditional shopping.

Some people consider that online shopping will replace the mall shopping, stores

will disappear in the future, while others argue that stores would unlikely to

be disappeared, it has its own advantages.

Most people shopping online because it is very convenient, there is no need

to go out, just click the mouse gently, they can buy the goods they want. In

addition, goods online are cheaper than entity shop that buyers can save a lot

of money. But even the coin has two sides. Online shopping also has advantages

and disadvantages. In recent years, we see a lot of news about online cheating,

and many buyers complain about poor quality of the goods, which is different

with the description.

However, the situation above is rare in traditional shopping store, because

the guest can communicate with the seller face to face. Buyers can also see

goods intuitively. But the traditional shopping does not convenience as well as

online shopping, for example, if people meet a traffic jam on the way to the

shopping which will affect the happy mood of shopping.

Many years ago, some scholars were strongly against the certification of

English test that was a must for a student to get the degree. So some colleges

canceled the rules. But recently, The Chinese first class university announced

that swimming skill is necessary for degree. It has been the hot issue, then

many people give their opinions.

On the one hand, some people are favorable of this regulation, because

swimming skill is really important. Most of the accidents happened in the river.

The swimming skill can protect them from dying. What’s more, foreign schools

take the swimming class as the regular lesson. So almost every foreign kid can

swim, which is the basic skill.

On the other hand, some people argue that even the student can’t swim, they

can’t be denied by lacking the swimming skill. They need the degree to find a

job. They are equipped with many skills and are capable of a lot of things.

Their ability has nothing to do with swimming skill.

I think that school should open the class for students to learn swimming

skill. If they fail, they still can make up by learning other lesson. The degree

can be got by many ways.

【参考范文】

From the picture we can see a family of three walking on a long red carpet. The son , well dressed, waves proudly in the middle while the father behind bends forward to hold the jacket and the mother in front rolls out the carpet, sweating.

It shows a common phenomenon nowadays that children are the focus of families, shouldering the hope of their parents. Parents arrange everything for their children and spare no effort to pave the way for their success. As a consequence, children become so reliant on their parents that they have no independent thought or creative ideas.

Such a situation is of great concern. In my opinion, overprotection and too much care are extremely bad for children’s development. Instead of doing everything for them, parents should encourage their children to overcome difficulties and inspire them to develop by themselves. Only in this way can they grow up to be independent and become truly successful.

A fun-filled, pain-free lifestyle equaling happiness actually reduces their

chances of ever obtaining real happiness. As a result,many people avoid the very

attempts that are the source of true happiness.And the real happiness always

contains some pain .In the other hand, true happiness has nothing to do with

fun. All those who always have so much fun actually may not be happy at all.

I have a bitter experience. When I was a child, I lived a poor life,and I

had a happy and meaningful life in my childhood. And my parents were always

respecting each other. And now we have some money,and our life has improved a

lot. To tell the truth, it is a good thing. Unfortunately,My father always goes

out and takes part in the gambling activities. And my mother sometimes quarrels

with my father. I am extremely unhappy about it. I think money doesnt equal

happiness. And pain-free lifestyle also doesnt equal happiness. The real

happiness is that everyone loves each other, and does everything useful for our

society. Most of my classmates support me. But some of them think money is

everything. In my opinion,we cant do things without money. But money cant take

the place of everything,such as your life,your time and your happiness.

Why to find suitable for you at the center of the target, you must ask

yourself these questions: where I know I to go and why? I why want to do is do?

What I want to stand and believe what? I get up every morning is for the sake of

what? The things I do every day is for the sake of what? In my life the most

important value? In fact, the reason why you set a goal is far more important

than the goal itself.

Dedicated to the pursuit of their goals and life value is clear why I have

these dreams. They spent a lot of time to think before every important aspect of

his life, they will think about who you are, what they want to do and want to

make what kind of contribution. If you do not have clear goals, also could not

find support for the urgent reason, finish your dream, you cant like

myself.

No dream, no hope, you cant do any meaningful things. If your whole life

just go with the flow, there is no goal that you cannot really love or respect

yourself.

If you just mix one day for a day, every day after work and weekend

holiday, are made with TV and boring dinner party to pass the time, then you

cant get any sense of achievement, there will be no satisfaction, let alone

happiness.

We all need to have a goal to release the full potential. The target is

larger, the greater the can inspire the potential of the. Studies show that many

people are not happy, feel pressure big, like the debate and argumentative,

because cant find meaning in life, goals and direction. They think life is too

目前环保还存在着许多问题。最严重的问题就是空气、水和土壤的严重污染。污染的空气对人类的健康十分有害。污染的水引起疼病,造成死亡。更有甚者,随着现代社会的迅速扩建,植被大大的减少。以下是小编为大家整理分享的爱护环境学生英语作文,欢迎阅读参考。

Now, our side of the car constant more up, the environment also increasingly worse! That the air around us there are many harmful substances。 Therefore, we want to Sue around things start to do。 For example, we can go to school by bike or walk, it can exercise。 If you have time can use less elevator, many climb stairs。 We can not only physical exercise, but also to protect our environment。

此刻,我们身边的汽车不断的多了起来,环境也越来越糟糕!以至于我们周围的空气有很多有害物质。所以,我们要苏身边的小事做起。比如,我们能够骑自行车上学或者步行,这样还能够锻炼身体。有时光的话能够少用电梯,多爬楼梯。我们不仅仅能锻炼身体,也能保护我们的环境。

爱护环境的学生英语作文

There are still many problems of environmental protection in recent years。 One of the most serious problems is the serious pollution of air, water and soil。 the polluted air does great harm to people’s health。 The polluted water causes diseases and death。 What is more, vegetation had been greatly reduced with the rapid growth of modern cities。

To protect the environment, governments of many countries have done a lot。 Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution。 Therefore, governments are playing the most 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。

保护环境

目前环保还存在着许多问题。最严重的问题就是空气、水和土壤的严重污染。污染的空气对人类的健康十分有害。污染的水引起疼病,造成死亡。更有甚者,随着现代社会的迅速扩建,植被大大的减少。

为了保护环境,各国政府做了超多的工作。采用了立法措施控制大气污染,保护森林资源和海洋资源,制止任何环境污染。因此,在当今的环保中政府起着最重要的作用。

我的看法是,为了保护环境,政府应当采取更具体的措施。首先,应当透过教育的方法使人们充分謒到环境保护的重要性。第二,应更加努力把计划生育政策付诸实施,因为人口多就意味着污染严重。最后,要严惩那些故意破坏环境者。使他们破坏环境就是毁灭人类自我。

On the other hand, the lack of knowledge about the importance of protecting environment hinders the solving of the problem. It is urgent that immediate and effective actions should be taken right away. First, more trees need to be planted to help improve and beautify the environment. Besides, stricter laws concerning global warming and irresponsible use of fuel resources have to be put into effect and achieved good results. In a word, there is a long way to go before we can take a comfortable world for granted again .

近日的雾霾天气,持续时间之长,范围之大,让我们不得不将环境问题列为重点关注的对象。打赢治理雾霾这样一场攻坚战和持久战,对环境、对人类身体健康,意义非凡。世界卫生组织(WHO)更是列出了世界空气最差的20个城市,可见环境问题的火热程度。环境问题作为重要的社会热点,很有可能在考研英语的作文中命题。据统计,环境问题作为考研英语六大热门写作话题之一,在99、00、09年均有设题(见下表)。今天我们就随都教授一起来学习一下。

一、闪光句型积累

保护和改善生活和生态环境:protect and improve the living environment and the ecological environment

增强环境意识:enhance the awareness of the importance of raise the consciousness about environmental protection

享受国家一级保护:enjoy first-class protection of the State

宣传教育开展保护野生动物:advocate to educate the public the protection of wild animals

帮助减缓全球变暖速度:help slow down the pace of global warming

使用清洁能源:burn clean fuel

加大污染治理力度:strengthen pollution control

二、精彩每日一句

KK教授的每日一句给出了这样一个有关环境的闪光句子,值得考生仔细研究和记忆:As we all know, our country has been under growing pressure to address the causes of air pollution as the PM2.5, a key indicator of air pollution, increasingly hits the new record and even smog frequently smothers the countrys large cities.

【参考译文】如我们所知,我国正面临着越来越大的解决空气污染的压力,因为PM2.5(空气污染的主要指标)不断的刷新纪录,雾霾甚至窒息了我国的主要城市。

三、PM2.5知识拓展:

严重的雾霾,让PM2.5这个数字飞入了寻常百姓家,下面我们一起来了解一下,以便积累考研英语作文的写作素材。

PM2.5的“PM”,是英语“particulate matter”的缩写,意为“细颗粒物”。大家在

家中都看到过这样的现象:一缕阳光射入屋内,光柱中有无数微尘在翻飞,这些微尘就是PM50和大于PM50的颗粒物。桌面上,落了一层灰,那是远远大于PM50的颗粒物。所以PM2.5是无法被肉眼看到的。但其虽小却具有极大危害。PM2.5携带了许多有害的有机和无机分子,是致病之源。细菌是人所共知的致病之源,PM2.5和细菌有得一比。能引发呼吸道阻塞或炎症,使得致病微生物、化学污染物、油烟等“搭车”进入体内致癌,影响胎儿发育造成缺陷,还能通过气血交换进入血管。

通过今天的学习,相信各位考生都积累了不少写作素材。的确,考研英语的写作题型是对考生英语综合能力的考察,同时,由于题目一般接近社会生活热点,所以考生在平日综合素质的积累也在一定程度上帮助考生获得高分。时间所剩不多,各位抓紧!预祝各位考生取得自己理想的成绩!

考研成功难又不难,一旦大家开始准备就要全力以赴。自制力差的学生可以找几个研友,互相激励,因为坚持下来也确实不容易,也看个人习惯,有的同学可能一个人学习更有效率;在这个过程中更主要的还有大家坚持的信念,坚持完成一件事情本身就是成功。

在三百多天的日子里,老师会一直陪伴着大家,里边的每条微博、微信、咨询都是温暖大家并激励大家前行的动力。奔跑吧,2016的考生们!

虽然有突破口、也有规律可循,但这并不意味着我们可以一劳永逸、高枕无忧,要知道,想要精通世界上任何一门语言,除非有天生的语言天分,否则偷不得半分懒,只能勤勤恳恳反复练习。一遍不懂读两遍,默念不行就大声念出来,遇到不认识的单词就查,不懂的句子就静下心来拆分结构。总之,读书百遍、其义自现,英语学习之路上没有笨蛋,只有懒人。 综上就是小编给大家提供的高分技巧,技巧就是牢固的知识点和强悍的答题思路,预祝所有考生2016考研有个好成绩。

小提示:目前本科生就业市场竞争激烈,就业主体是研究生,在如今考研竞争日

渐激烈的情况下,我们想要不在考研大军中变成分母,我们需要:早开始+好计划+正确的复习思路+好的辅导班(如果经济条件允许的情况下)。20xx考研开始准备复习啦,早起的鸟儿有虫吃,一分耕耘一分收获。加油!

Finally, we must control the pollution by law, according to which, polluted water and air exhausted from factories should be forbidden.

These are some of the measures that we can take to protect our environment and they are not hard tasks for us. Remember, the earth is the only planet we could live at present.

篇18:环境问题

全文共 2090 字

+ 加入清单

当前,威胁人类生存的十大环境问题是:

(一)全球气候变暖

由于人口的增加和人类生产活动的规模越来越大,向大气释放的二氧化碳(CO2)、甲烷(CH4)、一氧化二氮(N2O)、氯氟碳化合物(CFC)、四氯化碳(CCl4)、一氧化碳(CO)等温室气体不断增加,导致大气的组成发生变化。大气质量受到影响,气候有逐渐变暖的趋势。由于全球气候变暖,将会对全球产生各种不同的影响,较高的温度可使极地冰川融化,海平面每10年将升高6厘米,因而将使一些海岸地区被淹没。全球变暖也可能影响到降雨和大气环流的变化,使气候反常,易造成旱涝灾害,这些都可能导致生态系统发生变化和破坏,全球气候变化将对人类生活产生一系列重大影响。

(二)臭氧层的耗损与破坏

在离地球表面10~50千米的大气平流层中集中了地球上90%的臭氧气体,在离地面25千米处臭氧浓度最大,形成了厚度约为3毫米的臭氧集中层,称为臭氧层。它能吸收太阳的紫外线,以保护地球上的生命免遭过量紫外线的伤害,并将能量贮存在上层大气,起到调节气候的作用。但臭氧层是一个很脆弱的大气层,如果进入一些破坏臭氧的气体,它们就会和臭氧发生化学作用,臭氧层就会遭到破坏。臭氧层被破坏,将使地面受到紫外线辐射的强度增加,给地球上的生命带来很大的危害。研究表明,紫外线辐射能破坏生物蛋白质和基因物质脱氧核糖核酸,造成细胞死亡;使人类皮肤癌发病率增高;伤害眼睛,导致白内障而使眼睛失明;抑制植物如大豆、瓜类、蔬菜等的生长,并穿透10米深的水层,杀死浮游生物和微生物,从而危及水中生物的食物链和自由氧的来源,影响生态平衡和水体的自净能力。

(三)生物多样性减少

《生物多样性公约》指出,生物多样性“是指所有来源的形形色色的生物体,这些来源包括陆地、海洋和其他水生生态系统及其所构成的生态综合体;它包括物种内部、物种之间和生态系统的多样性。”在漫长的生物进化过程中会产生一些新的物种,同时,随着生态环境条件的变化,也会使一些物种消失。所以说,生物多样性是在不断变化的。近百年来,由于人口的急剧增加和人类对资源的不合理开发,加之环境污染等原因,地球上的各种生物及其生态系统受到了极大的冲击,生物多样性也受到了很大的损害。有关学者估计,世界上每年至少有5万种生物物种灭绝,平均每天灭绝的物种达140个,估计到21世纪初,全世界野生生物的损失可达其总数的15%~30%。在中国,由于人口增长和经济发展的压力,对生物资源的不合理利用和破坏,生物多样性所遭受的损失也非常严重,大约已有200个物种已经灭绝;估计约有5000种植物在近年内已处于濒危状态,这些约占中国高等植物总数的20%;大约还有398种脊椎动物也处在濒危状态,约占中国脊椎动物总数的7.7%左右。因此,保护和拯救生物多样性以及这些生物赖以生存的生活条件,同样是摆在我们面前的重要任务。

(四)酸雨蔓延

酸雨是指大气降水中酸碱度(PH值)低于5.6的雨、雪或其他形式的降水。这是大气污染的一种表现。 酸雨对人类环境的影响是多方面的。酸雨降落到河流、湖泊中,会妨碍水中鱼、虾的成长,以致鱼虾减少或绝迹;酸雨还导致土壤酸化,破坏土壤的营养,使土壤贫瘠化,危害植物的生长,造成作物减产,危害森林的生长。此外,酸雨还腐蚀建筑材料,有关资料说明,近十几年来,酸雨地区的一些古迹特别是石刻、石雕或铜塑像的损坏超过以往百年以上,甚至千年以上。世界目前已有三大酸雨区。我国华南酸雨区是唯一尚未治理的。

(五)森林锐减

在今天的地球上,我们的绿色屏障——森林正以平均每年4000平方公里的速度消失。森林的减少使其涵养水源的功能受到破坏,造成了物种的减少和水土流失,对二氧化碳的吸收减少进而又加剧了温室效应。

(六)土地荒漠化

全球陆地面积占60%,其中沙漠和沙漠化面积29%。每年有600万公顷的土地变成沙漠。经济损失每年423亿美元。全球共有干旱、半干旱土地50亿公顷,其中33亿遭到荒漠化威胁。致使每年有600万公顷的农田、900万公顷的牧区失去生产力。人类文明的摇篮底格里斯河、幼发拉底河流域,已由沃土变成荒漠。中国的黄河流域,水土流失亦十分严重。

(七)大气污染

大气污染的主要因子为悬浮颗粒物、一氧化碳、臭氧、二氧化碳、氮氧化物、铅等。大气污染导致每年有30-70万人因烟尘污染提前死亡,2500万的儿童患慢性喉炎,400-700万的农村妇女儿童受害。

(八)水污染

水是我们日常最需要,也上接触最多的物质之一,然而就是水如今也成了危险品。

(九)海洋污染

人类活动使近海区的氮和磷增加50%-200%;过量营养物导致沿海藻类大量生长;波罗的海、北海、黑海、东中国海(东海)等出现赤潮。海洋污染导致赤潮频繁发生,破坏了红树林、珊瑚礁、海草,使近海鱼虾锐减,渔业损失惨重。

(十)危险性废物越境转移

危险性废物是指除放射性废物以外,具有化学活性或毒性、爆炸性、腐蚀性和其他对人类生存环境存在有害特性的废物。美国在资源保护与回收法中规定,所谓危险废物是指一种固体废物和几种固体的混合物,因其数量和浓度较高,可能造成或导致人类死亡,或引起严重的难以治愈疾病或致残的废物。
