At the same time, the places you have been to, the things you have bought, and even your every search, every information transmission, and downloaded applications will be sorted into data, making a clear judgment on your activity rules and even your ideological trends, which may make people lose the protection of personal privacy at any time.

Requirements: choose a good angle, determine the intention, clarify the style (except poetry), write a title yourself, and write a composition of not less than 800 words.

Writing instruction

This material reflects the theme of "technology and life" in the composition of the college entrance examination. The material can be divided into two levels: the first level tells about the great convenience brought by a small smart phone in the era of big data, and the second level tells about the hidden dangers brought by mobile phones to people's lives. This material objectively, comprehensively and truly reveals the advantages and disadvantages of high technology from both positive and negative aspects, and has obvious speculative color.

Everything has two sides. However, living in the high-tech era, people often only care about enjoying convenience and feeling fun, but often ignore the extremes meet. Unconsciously, people become slaves of high technology and even become victims.

To interpret this material, we should examine it with a scientific, prudent, objective and fair attitude, and we should not lose sight of one thing and lose sight of another. It can be analyzed from three dimensions: first, the "benefits" brought by high technology. If you have a mobile phone, people can chat, shop and even have video conversations, and see Wan Li without any obstacles; With robots, the space shuttle can attach heat-proof tiles to complete long-term welding in dangerous positions; With rockets, people can learn more about the earth and make China's dream of flying for 5,000 years come true. It can be said that science and technology achieve dreams; Science and technology have promoted human progress; High-tech has inserted soaring wings into modern life. Second, the "disadvantages" brought by high technology. Whether it is the extinction of species caused by environmental pollution or the loss of personal safety, whether it is the spread of negative comments or online fraud, it has caused great threats to mankind. It can be said that high technology threatens human security; Internet exposes people's privacy; Hi-tech, it is not easy to say I love you; Are caused by the internet; Pay attention to network security. Third, technology is a double-edged sword. Simple affirmation or negation is not rigorous. In the face of high technology, the key depends on how people deal with and use it, learn to turn disadvantages into advantages, and be masters of their own destiny. From this perspective, we should understand: don't be a slave to data (don't be a simple low-headed family); Seek advantages and avoid disadvantages, so that high technology can better benefit mankind; Convenience can also bring inconvenience; Everything has two sides; The world is dialectical.

Materials and applications

Powerful material 1:

In ancient times, many people were seriously ill, and doctors could do nothing but watch patients die painfully. But now because of the development of science and technology, most intractable diseases have been successfully cured, and people don't have to worry about getting sick.

Use case section:

Science and technology is the road to a strong country, and science and technology is the first driving force for the progress of the Chinese nation. How can we live a happy life today without science? Without science and technology, how can we have a comfortable material life and spiritual enjoyment? Without the progress of science and technology, how can we eat hybrid rice 2? Where can I wear cotton-padded jacket? Where can I live in a tall building? In ancient times, people were seriously ill and had to wait for death; In modern times, because of the development of science and technology, most intractable diseases have been successfully cured. People live long and carefree, relying on the power of science and technology.

Powerful material 2:

In the 20th century, the international community made unremitting efforts to ban biological weapons and made some progress. However, in the 2 1 century, the potential threat of biological weapons has greatly increased, and bioterrorism marked by the "anthrax incident" in the United States poses a real threat to international security.

Use case section:

High-tech has brought the Internet, gradually making people unable to speak, write or make friends. High-tech brings population expansion and resource shortage, and resource consumption is getting faster and faster, so a resource grabbing war is bound to break out. In addition, the potential threat of high-tech biological weapons is gradually increasing, and bioterrorism marked by the "anthrax incident" in the United States has posed a real threat to international security. It is not sensational that science and technology create human beings and eventually destroy them.

Powerful material 3:

It is reported that there are about 400 million discarded mobile phones in the world every year, including nearly 654.38 billion in China, and the total weight of these mobile phones is 654.38+0 million tons. Waste mobile phones contain harmful substances such as lead and cadmium, which will cause serious pollution if discarded directly. The pollution intensity of a waste mobile phone battery is 100 times that of ordinary dry batteries, which can pollute 60,000 liters of water. If the used mobile phones are transported to the garbage dump for incineration, the plastic shell will also produce chlorine-containing toxic substances, even the first-class carcinogen "dioxin".

Use case section:

Everything has two sides. As a high-tech product, mobile phone has really brought great convenience to people's lives and made great contributions. However, a large number of used mobile phones contain harmful substances such as lead and cadmium, which are directly discarded and seriously polluted. Incineration and destruction of used mobile phones will produce toxic substances, even the first-class carcinogen "dioxin". You didn't see that the invention of air conditioning made life comfortable, but it caused frequent air conditioning diseases; X-ray can see through the body and examine the patient, but some people use it to identify the sex of the fetus and ignore human life; Transgenic technology improves crop yield, but it also "evolves" pests. All these have advantages and disadvantages. How to seek advantages and avoid disadvantages should arouse people's deep thinking.

"network" aria

Now is the era of "trapping" the world.

Network, you are Prometheus, stealing the flame of Zeus, lighting the lightning, illuminating the darkness before dawn, making the wind of dawn reverberate in your ears, and the world is wonderful because of you. Internet, you fire thief, you stole the light, but also brought darkness.

Give me back my privacy. This is an era of individuality, but it is also an era of lack of privacy. People are dissected and dismembered by big data bit by bit, and exposed to the public without leakage. Network, you stole the fig leaf of human beings and turned people into naked "invisible people"! The "prism incident" that broke out not long ago reflects the hidden worry of information security. High-tech stole our information invisibly, and defeated the enemy without fighting. Not long ago, a girl named Qiqi, who was at a loss because of a Weibo, was mercilessly ridiculed by someone who dug up her personal information on the Internet, and finally committed suicide in anger. Everyone has secrets in his heart, just as every bud has worries. Forcibly peeling off the petals will definitely make the buds wither and mercilessly uncover personal privacy, which will definitely lead to human tragedy.

Give me back my distance. Living in the internet age, although thousands of miles apart, we can talk face to face, so the distance between people is very close, but the distance between hearts is very far. I have recalled countless times that "after three months of war, a letter from home is worth a ton of gold". Although the war continues, and we live in different parts of the world, we can "walk along Wan Li Road". However, in this era of big data, neon lights adorn the night sky, and mobile phones are the mainstay, which has become the protagonist of the party. When "let's play with mobile phones and have dinner by the way" has become the mantra of young people, we can't help but sigh that human feelings have changed: without Zhu Ziqing's feeling of "and heaven remains our neighbourhood, how can I get it", there is the helplessness of the Canadian female writer's feeling that "the farthest distance in the world is not that you are at the ends of the earth, but that I am in front of you, but you don't know I miss you". Network, you stole the distance, where can you find the hometown of your heart?

Give me back my poetic life. How can we not yearn for Yasunari Kawabata to see the flowering of begonia at 4: 30 in the morning, for Rousseau's cabin by Walden Lake, for Wilde to look up at the stars in the gutter, and for Cangyang Gyatso to walk through the snow in Xun Mei? On the other hand, there are no poems and paintings at present, and screen slaves are everywhere. When praising and brushing Weibo has become the main theme of life, where has our real life gone?

Network, when I put you in the spotlight again, I studied it carefully and finally got a glimpse of your true colors. You were just a tool in the high-tech era, and it has nothing to do with good or bad, merits or demerits. If properly used, it can make people play around the world, transmit information, spread knowledge and benefit mankind. If it is not properly controlled, it can also deprive privacy and spread rumors. Sexual violence and high-tech crimes push people into the abyss of perdition.

Advantages and disadvantages, black and white, there is no definition between the two poles, but the extremes will be reversed, depending on how you control it. The internet can send you to heaven or hell. How to make high technology benefit mankind depends entirely on human wisdom.

Comments: This essay begins with "Internet, you fire thief, you stole the light, but also brought darkness", both sides are accurate. Then, from the aspects of invasion of privacy, stealing distance, losing poetic life, etc., this paper emphatically analyzes the disadvantages brought by the network. Finally, re-examine, highly summarize the advantages and disadvantages of the network, and draw the conclusion that "how to make high-tech benefit mankind depends on human wisdom", closely follow the topic and remind people. The article is rich in content, rigorous in interpretation, exquisite in language and rich in literary talent.

Terminal cancer

"What about your family?" "No, I live alone. Doctor, just say it! " "Young lady, your situation is not optimistic. Let me get this straight, this is the third stage of gastric cancer ... "

Zhen' ai doesn't remember what the doctor said later. Only then did she know how shocking the word "gastric cancer" displayed on Baidu's mobile phone screen was in the bumps of the bus. She stared at the phrase "the average cure rate in the middle and late stage is 30%" and waited for a while. Suddenly, she heard the announcer announce that the station "Chang 'an Road has arrived", and then she came to her senses and got off in a hurry.

Back to the rental house, Zhen Ai used her mobile phone to check the balance of her bank account. How can we avoid the clutches of death? Outside the window was a restless crowd, and her eyes were red with the scorching sun.

It was not until the dark sky was dyed black and neon lights danced strangely on her bed through the glass that Zhen 'ai's thoughts were pulled back by the tips of her mobile phone. When I opened Weibo, a blog post appeared: "This morning, on the No.95 bus, a young woman just sat in her seat and played with her mobile phone, completely ignoring the old man standing beside her and the strange eyes around her ..." She hurriedly clicked on the picture and suddenly showed that she was staring at her mobile phone. She collapsed in an instant. When I opened the comment area, there were more than 5000 comments. All people incarnate as messengers of justice, stand on the altar of morality and accuse this kind of "social garbage" of "disrespect" and "quality corruption". Zhen Ai opened her mouth and tried to say something, but she didn't say a word.

The next morning, this accusation of "justice" quickly evolved into human flesh search. Someone exposed Zhen Xuan's real name, age, telephone number and work unit on the Internet ... No one cared about her swollen eyes and desperate expression in the picture. People only know that they are madly slandering and slandering. The indignant people kept forwarding blog posts, making phone calls and making fun of her with all the vicious words in the world. Cherish has become the target of public criticism and has been pushed to the forefront. She curled up on the sofa with her knees, feeling like a child who accidentally broke a vase and was covered in sewage.

Two days later, Zhen' ai went to the hospital for reexamination. When I was waiting in line to register, I suddenly heard bursts from somewhere: "Isn't she the woman who didn't give up her seat on the bus?" For an instant, all eyes were on her face. These eyes were like stingers, blinding her and only hearing ridicule, abuse and shouting. Zhen' ai was overwhelmed by this anger. She fainted to the ground and vaguely heard a shrill scream: "What a suck! Karma! "

After waking up from a deep coma, Zhen Zhen has been lying in bed for three days. She doesn't remember what happened in these three days. Unconsciously, she turned on her mobile phone and found that in just a few days, the focus of people's attention in Weibo had already become the 16-year-old girl who announced the live broadcast of the suicide process. The girl asked in despair, "Can't I die?" Some netizens said: "No, you must die. I have been waiting for a long time. " Others said: "Liar, pay for my traffic!" In this way, a teenage boy died.

Think about what happened to me these days, think about the tragedy of teenage girls, and then think about the foul language on the Internet. Zhen Ai gave a hysterical cry: "Oh, my God! In the late stage of cancer, it is me or this crazy online world! "

Comments: Through the narrative of a terminally ill patient's experience, this narrative vividly and intuitively exposes the harm that the Internet has brought to people in the high-tech era. The story is complete and thought-provoking. The article focuses on the description of the environment to set off the psychology of the characters and promote the development of the story, such as "there is a restless crowd outside the window, and the sinister sun reddened her eyes" and "until the sky was dyed black, neon lights danced on her bed through the glass" and so on. The author skillfully ends with the protagonist's hysterical cry, which inspires the deaf and reveals the theme.
