不知从何时起，餐厅、公交、地铁，一眼望去每个人都在低着头，用大拇指上下不断翻动手机。“低头族”的队伍正在逐渐壮大。

与其说手机不离开“低头族”，不如说“低头族”离不开手机。中国某知名大学做了一项学生调查，有八成人表示自己一天不带手机会产生焦虑感。由此可见，人们正在对手机产生依赖，这种依赖造就了“低头族”这个群体。

人，无论如何不要低下头。

如果低下了头，连基本的情感都会逐渐流逝。央视一则新闻报道：“青岛某家庭聚餐，老人因子女总是低头看手机而与自己敷衍交谈，愤然摔盘离席。”这反映出了许多“低头族”家庭的春节实况。对“低头族”而言，春节的乐趣就是看自己晒的照片又有几个人点赞。陪孩子凌晨看盛世烟火时的幸福，听父母餐桌上讲陈年往事的感动，同朋友逛庙会时的喜悦，这些情感在“低头族”身上早已消失，剩下的只是刷朋友圈时那张面无表情的脸。他们的情感早已被手机掠夺。

如果低下了头，生活品质会大幅降低。不知你是否发现，近年来，周末图书馆的座位逐渐有了虚席;晚上漫步公园的人愈来愈少;初春踏春的景点早已没有拥挤的人群。这一切，都“得益”于“低头族”的壮大。“低头族”的情感早已丧失，又怎会饶有兴致地阅读、阅读、赏景、出行呢?“低头族”在朋友圈微博总是发动态，但是从不会在年末“蓦然回首”，因为他们的生活品质太低，一年下来一件引为聊资的事都没有。他们的生活早已被手机挤满。

如果低下了头，人性会逐渐泯灭。“低头族”的情感与生活早已被手机占据，每天总是一副“无所谓”的模样，做任何事情都觉得没有意义。“老人街上摔倒无人肯扶”的新闻近年来比比皆是，这正是因为“低头族”的壮大，而他们的道德底线、规则意识、人之本性早已烟消云散，剩下的只是一个被手机支配的躯体。那么敢问，活着还有何意义?他们的人性早已被手机扼杀。

放下手机，多陪父母散一次步，多和朋友们约一场球，多抬起头欣赏一次诱人的晚霞，无论如何不要低下头。

雾霾天气是自然和人为污染环境所形成的，面对这种恶劣天气，我们只有采取各种措施尽量避免其给人们正常生活和健康带来的危害。

1.减少外出。抵抗力弱的老人儿童以及患有呼吸系统疾病的易感人群应尽量减少出门，或减少户外活动，外出时戴口罩防护身体，防止污染物由鼻、口侵入肺部，外出归来后，应立即清洗面部及裸露肌肤。

2.减少户外锻炼。雾霾天气气压低，能见度低，空气中悬浮大量尘埃等有毒颗粒，患有支气管哮喘、慢性支气管炎、阻塞性肺气肿和慢性阻塞性肺疾病等慢性呼吸道疾病患者，应尽量避免户外锻炼，以免诱发慢性病得发作或加重。同样大雾天气压较低，高血压、冠心病等慢性病患者不宜做户外锻炼，以避免诱发心绞痛、心衰。中等和重度霾天气易对人体呼吸循环系统造成刺激，尤其是在早晨空气质量较差。通常来说，若无冷空气活动和雨雪、大风等天气时，锻炼的时间最好选择上午到傍晚前的空气质量好，能见度高的时段进行，地点以树多草多的地方为好，霾天气时也应适度减少运动量与运动强度。

On the other hand , more and more teenagers are addicted to virtual world and they all play computer games everyday they want, leading to a terrible result.

[网络的坏处英语作文

November 11 is Bachelor’s Day, it is a joke that shopping can make up the

loneliness on that day, the manufacturers sense the great business, so they give

great discount on that day, people are attracting by the discount, they buy a

lot of things on that special day. But we known that people lose their wisdom

when they buy things, most things are useless.

Today, shopping online brings great discount, the price of the product will

be cheaper online, so people like to shopping online. When the holiday comes,

the products even get cheaper, customers always wait for the chance to pay the

lower price. It is said that as so many buy things on Bachelor’s Day, the

express delivery congested, customers got their stuff very late. It is more

ridiculous that a couple divorced because the wife bought too many things

online.

Now December 12 is coming soon, the discount is being presented, it is a

great lure that customers can’t control themselves. Shopping online should be

rational, we just buy what we need, the rest even is cheaper, but without value,

we must realize is a waste.

Now, we can get cheaper stuff not only online, we should control ourselves,

we buy what we are using, we can use the money to do meaning thing.

With the coming ofnational day, I have a one week holiday.

I really expect to it, because I wantto have a short trip during these days. I will travel toJiuzhaiValleywith my parents for three days.

I have heard that the scenery ofJiuzhaiValleyis very beautiful in autumn and it’s the best time to travel there.

Autumn is my most favorite season so I wantto enjoy the beauty of such a wonderful place.

I do some preparations for thistrip.

For example, I search the Internet to see the travel raiders and I haveknown where the most attracting place is and where to live in.

I am sure itwill be a wonderful journey. There are only several days for the coming trip,but I have been too excited to wait.

Nowadays, some discussions about the childrens education and management

have raised the whole social concern. It seems not only about childrens

personal development, but also about the whole countrys future.

There are two main views in debate, which of them is that children should

obey the rules set by parents and teachers. The other is that less control will

help children to deal with their future adult life.

As for the former, the advantages of it seem to be very apparent, which of

them is that children can make a distinction between right and wrong things. And

they will have a sense of principle and responsibility. Of course, the

disadvantages are also very clear. Firstly, children will be lacking in

imagination and creation. Secondly, they cannot make up their mind on their

own.

Concerning the latter, the view seems to be reasonable because in this ways

these children are more clever and active to create something special. However,

the drawbacks couldnt be ignored as a result of a problem that children cannot

get a clear understanding of their lifetime.

Combining the both points, as far as Im concerned, parents and teachers

are supposed to instruct children to obey the primary principle when they do

some deeds. Moreover, children need more freedom to realize their dreams. Only

in this way can the problem be solved perfectly.

In conclusion, we cant only support one side simply. On the contrary, we

ought to choose different measures to educate children flexibly.

if you want to understand adversity, take two identical acorns from the same oak tree and plant them in two different locations. plant the first in the middle of a dense forest, and the other on a hill by itself.

要是你想理解什么是逆境，就去拿两颗从同一棵树上摘下来年龄相同的橡树果，并且把它们种到不同的地方。第一颗种在浓密的树林当中，而另外一颗则单独种在一座山上。

heres what will happen. the oak standing on a hillside is exposed to every storm and gale. as a result its roots plunge deep into the earth and spread in every direction, even wrapping themselves around giant boulders. at times it may seem the tree isnt growing fast enough—but the growth is happening underground. its as if the roots know they must ported the tree from the threatening elements.

事情的结果便是这样。那颗长在山上的橡树经历了大风大雨，结果它的根深深地扎进了泥土中间，并不断向四周扩张，甚至把自己置身于巨大的石块当中。有时它可能看起来长的不是很快，但这时它却在地下悄悄生长着，好像它的根知道自己必须快速生长来保护树木免受自然危害的影响。

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

boring!

网络能使我们获取信息，网络也能使我们沉醉不醒。

这是一个真实的故事，这个故事就发生在我身边。我有一个哥哥，打小学起，成绩一直不错，次次考试都是前几名，妈妈以他为骄傲，可是，好景不常，上了初中后，我家添了一台电脑，就这样他迷上那个了网络游戏，每天都守在电脑旁。开始，妈妈尝试着去劝说他，想让他认识到迷恋网络游戏的危害，可他听了后，像个没事人一样，依旧我行我素，日子久了，妈妈的劝说就变成了责骂和鞭打，可这对一个正处于青春期的男孩并没有多大的作用，反倒弄巧成拙，妈妈越是责骂和鞭打，他就越反抗。

爷爷身体一直不太好，爸爸又时常不在家，家庭的重担就落在妈妈身上，最近，爷爷的身体越来越不好了，医生说要住院观察，庞大的医疗费也增加了家庭的经济负担。可这些哥哥都没有看在眼里，他依旧玩着他的游戏，哥哥的这些表现使妈妈更加生气，妈妈每天以泪洗面，可哥哥并没有为此发生改变。

网瘾到底有多大的危害呢?竟然可以使一个好学生变成一个问题少年?

网瘾是毒药，他会使人上瘾，他会使人陷在网络游戏里无法自拔。

A couple of years ago, individuals can only take courses at real schools. In other words, only when they go out to schools by themselves will they have lessons which they want to have. However in recent years, with the development of internet and education mode, online teaching has become increasingly common. This kind of teaching mode means that a student just needs to have classes sitting in front of a computer at home, which appealing to lots of people.

It is widely acknowledged that online teaching has its apparent merits. First and foremost, shared resources online are accessible to all people, which costs a little at the same time. This feature brings about significant benefits especially to those who fail to afford that many courses at real schools. Secondly, online teaching makes it come a reality that one is able to study at the best pace suitable for him according to his own schedule. Last but not least, studying at home without going out is much more comfortable as well as convenient to busy people in contemporary society.

Meanwhile, there is no denying that online teaching also has demerits that cannot be dismissed. For one thing, online teaching, not like face-to-face teaching, lacks interaction between teachers and students, causing teachers not to receive feedbacks from students in time. For

another thing, for people who are poor at self-discipline, learning online at home will be a less effective way since they are easier to be distracted by other things. Besides, all of online teaching courses are ready-made rather than custom-made, that is to say, it is troublesome to be flexible when changes are needed.

近日,一些在网上编造谣言者被公安机关依法拘留,一批传播谣言的互联网站被依法查处.如果说,这是网络虚拟世界里的一场地震的话,那么网络传谣无疑是这场地震的导火索.而由网络谣言引发地震的烈度之深、破坏力之大,在让我们震惊的同时,也不禁引发广大网民的深思：网络之大,是否可以包容一切?网络自由,是否足以蔑视一切?

在当下,网络,与其说是一种学习和交流的工具,毋宁说是已经成为了人们的一种生活方式.尤其是对那些“资深网民”来说,网络甚至已经成了须臾不可分离的生活必需品.而依靠网络的张力,资讯的传递更加迅捷,民意的表达更加直接,政策的传达更加深入,精神的交融更加深刻,这也正是网络的最大魅力.

也正因为此,谣言一旦见于网络,就像病毒的传播,无形而迅猛.国外有一句关于谣言传播的名言：“当真理还在穿鞋,谣言已经走遍了天下.”德国纳粹戈培尔也曾说过,“重复是一种力量,谎言重复一百次就会成为真理.”可怕的是,网络先天就是这样一种载体,它让生产可以变得无形,它让重复变得简单到可以忽略成本,而它的破坏力却足以引发“地震”.

有人说,网络是一个虚拟世界,虚拟世界的魅力就在于不受现实世界的束缚,事实果真如此吗?试想,有一天,当我们打开网络,新闻频道净是愚人节消息,网上商城都是假冒伪劣,娱乐频道皆是谣言八卦,这样的网络,你是否可以容忍?据不完全统计,全国目前有5亿多网民.这其中,有成年人,也有孩子.如果说成年人尚有分辨能力,那么对于不谙世事的孩子来说,整天泡在虚假的网络环境里,对于他们的成长将意味着什么?“虚拟”与“虚假”,虽只一字之差,但确确实实是谬以千里.

说到底,网络不是空中楼阁,它只是现实世界的延伸,是现实世界在虚拟空间中的映射.那么,对于现实世界的管理,也同样适用于网络.要净化网络环境,让网络成为健康的社会文化生活的一部分,就必须铲除网络谣言产生的土壤,必须像根除病毒一样将网络传谣消弭于无形.只有这样,才能确保网络虚拟世界的秩序和安全,才能给孩子们营造一个积极向上的成长环境,才能使虚拟和现实相映成辉,共同进步.

Childhood in my grandmothers house, saw the hen sat in the nest to scare

her, shedid not run, I felt very unusual.

Go and ask the Father knows, the hen is sitting, I am very surprised. At

the same time, there is a strange idea -- the hen can hatch the chicken, I also

have hatched chicks! So, I also got some egg on the quilt, and then he climbed

into bed lying in bed, put the egg on your ass..

I thought: I can also be hatched chicks, I am great superman!

But after several hours did not see a little action, I urgent cry.

“Shan Zhai” is the new words to express fake products, people use it to express the highly imitated products, some manufacturers produce the Shan Zhai products to make great profit, but it is so unfair to the customers, they pay so much money in the purpose of buying the genius stuff instead of the fake products. Fake products not only cheats people’s money, but also brings people dangers. Such as the medicine, if people buy the fake one, once they eat it, they will feel uncomfortable and get the illness, the most terrible situation is that they will kill themselves. Fake product is so harmful, though the government has taken some action to ban it, still people sold it, it is the temptation of profit that makes people sold it. What if their relatives have bought the products, so in order to keep people healthy, fake products should be banned.

“山寨”是用来表达伪劣产品的新代言词，人们使用它来表达高仿产品，一些生产商生产山寨产品以此来获取巨大的利润，但是这对于顾客来讲是不公平的，他们花费了这么多的钱，只为了买到真的产品而不是假的产品。伪劣产品不仅欺骗了人们的钱，而且给人们带来了危害。比如药，如果人们买到伪劣的，一旦服用，就会感到不舒服，生病，最严重的情形就是因此失去生命。伪劣产品是如此的有害，虽然政府已经采取了一些措施来禁止售卖，但是仍然有人兜售，他们是抵挡不住金钱的诱惑。如果他们的亲戚买了这些产品，会怎样呢，因此为了人们的健康，不要再卖伪劣产品了。

Almost every kid will be asked the question of whom do you like better,

your mother or your father. There is no doubt that mother is very great as she

gives you the life, while father is also of importance. Father’s Day is invented

to show gratitude to fathers. Its coming has a story.

The first person to propose the idea of Father’s Day was Mrs. Dodd in 1906.

She wanted a special day to honor her father, whose wife passed away many years

ago. At first, Mrs. Dodd wanted Father’s Day to be celebrated on her father’s

birthday, but later President Johnson signed a paper to declare the third Sunday

of June was Father’s Day. Since then, it became an international day. It is not

only to honor one’s father, but also the fathers of all the people.

Father’s Day reminds people to show gratitude to their fathers, who loves

you all the time and no matter what difficulty you meet, he will stand by your

side. So however busy we are, we should call them now and then.

I classified the information and wrote down tourist sites. During the trip, I become much independent. Sometimes I even walked down the foreign street by myself, appreciating the beautiful scenery.

首先，这是我第一次出国旅行。我和我的朋友们做了很多准备工作，我们看了旅游指南，选择对我们有用的信息。我把信息分类并写下与旅游景点相关的信息。在旅途中，我变得更加独立，有时我甚至可以独自走在国外街头，欣赏美丽的风景。

Secondly, I broadened my vision and enrich my mind. Before I came to Thailand, I needed to read some information, then I got to know this countrys culture and their tradition. When I was in Thailand, I could feel its religious belief. Whats more, there were so many foreigners here, and I talked to them happily.

其次，我扩宽了我的视野，丰富了我的思想。来泰国之前，我需要提前阅读一些信息，然后我了解了这个国家的文化和传统。我在泰国的时候，我能感觉到它的宗教信仰，更重要的是，这里有很多外国人，我可以跟他们愉快地交流。

Traveling is a good way to learn knowledge, and I know the importance of English. It is the key to know about the world.

旅行是一种很好的学习知识的方法，而且我也了解英语的重要性，它是了解世界的关键。
