SCIENCE & TECHNOLOGY

Technology is an important part of our lives. We use computers and other electric equipment at work and in the home. However, some people believe we rely too much on machines, and that the more technology improves, the lazier and weaker humans will become.
Technological advances are changing our lives very rapidly. Nowadays we can't do without such gadgets as mobile phones, PCs, digital tape recorders, air conditioners, fax machines and so on. Many people feel ill at ease without their laptop computers or G PS navigation systems.
In my opinion, technology facilitates our lives and saves our time. Computers help us do the most difficult sums and investigate complicated data. People do business, communicate and do the shopping via the Internet. It is much easier to do housework nowadays, thanks to electric equipment such as microwave ovens, washing machines and so on.
However, many people say that technology makes us lazier and weaker. For example, such technological developments as the telephone and the Internet have made communication much easier, but they can cause the loss of social interaction. A lot of people prefer communicating through a keyboard than face to face. That is why people don't meet as often as they did in the past. A lot of people are fond of watching TV and playing computer games. They spend hours in front of the screen. They have no time to read books or to communicate with their friends. They move less, speak less and they even think less. Of course, such way of life does much harm to their health.
To sum up, people should continue to develop technology, but they must do it wisely. Otherwise we may regret in the future.
Some people say that technical devices do more harm than good. However, others think that it is impossible to live without computers or mobile phones nowadays.
Nowadays people can't imagine their lives without different technical devices. Every day we use computers, laptops, mobile phones, i-Pods, digital tape recorders and so on.
I have always wondered if our lives could be better without these technical devices. Personally, I can't do without my computer as it helps me study. For example, it helps me prepare reports and create beautiful presentations. Besides, the computer is a great source of entertainment. I often play computer games, watch films or listen to music. The Internet helps me learn the latest news, access useful information, communicate with my friends and what not. A mobile phone is a vital part of my daily life. It gives me an opportunity to be reachable everywhere and to keep in touch with my friends.
However, many people say that technical devices enslave those who use them. Besides, they do much harm to our health. For example, if people spend much time in front of the screen, they have problems with their eyesight and sleep. They don't go out or exercise, they feel exhausted and depressed. Computer games can cause addiction and make people aggressive. As for mobile phones, they use electromagnetic radiation which can influence our health in a negative way.
To conclude, I would prefer a technological way of life to a natural one, though it has a number of disadvantages. In my opinion, modern society can't do without progress and technology. People can avoid the risk to human life and health if they use technological devices wisely.
Mobile telephones have become very popular nowadays. However, some people say that their use should be restricted.
Mobile phones have changed people's lives. They give us an opportunity to stay in touch and to be reachable everywhere. It is very comfortable, especially for the busy modern lifestyle. So, the mobile phone has become a vital part of our daily lives and it is difficult to imagine how people lived without mobile phones in the past.
In my opinion, the mobile phone is a very useful device. Thanks to it, I can access people 1 need to speak to and I can never miss anything important. If I need some help, I just call my friends and they rush to rescue me. If I have a meeting and I'm late, I can send an SMS with my excuses. It is very fast and convenient. What is more, with the help of my mobile phone I can access the Internet, send and receive photos and video, play games, listen to music and what not.
However, mobile phones have some disadvantages. Firstly, they deprive people of privacy and it is almost impossible to relax with your mobile phone on. Secondly, many people are worried about the harmful influence of mobile phones on their health. Mobile phones use electromagnetic radiation. Scientists say that there is no significant health effect from mobile phone radiation. But still it is better not to use your mobile phone too often.
To sum up, a mobile phone is very useful because it gives us the freedom of movement. It has made communication much easier. But we shouldn't forget that a face-to-face conversation is much better than just a telephone talk.
Most people are used to sending e-mails and SMS messages. But others still prefer traditional paper letters or phone calls.
Nowadays more and more people are sending e-mails and SMS messages, while others say that it may lead to the loss of social interaction.
Personally, I communicate with my friends through e-mails and SMS messages. To my mind, they have a number of advantages. Firstly, both e-mails and SMS messages are rather cheap and quick. Secondly, they are non-intrusive. In comparison with a call, they do not interrupt a person if he or she is in the middle of a meeting and can't answer you right now. Besides, there are no standard rules for writing e-mails and SMS messages, and a lot of words can be shortened. Their objective is to convey a comprehensible message as quickly as possible. That is why traditional rules of grammar, spelling and punctuation are largely ignored.
However, a lot of people say that sending an e-mail or SMS message is not the same as writing a letter. Paper letters are usually intimate and long. They give you an opportunity to tell your friends or relatives all the latest news and to express your feelings. As for e-mails and SMS messages, they are often short and impersonal. You can't see the sender's handwriting, you can't feel the crisp paper and you are not likely to re-read these messages. But I still believe that sending e-mails and SMS messages is more effective than writing letters.
To conclude, when we are short of time, e-mails and SMS messages are the best way of communication. But if we want to give or learn more detailed information, letters or phone calls are better.
The Internet has revolutionized the way people live and work. However, some people think it has more drawbacks than advantages.
The Internet is a great source of information and entertainment for many people. It has made possible new forms of social interaction and has become a major source of leisure.
Personally, I can't imagine my life without the Internet. Thanks to it, I have an opportunity to access news, documents, images, sounds, video, games and sports reports, to make friends, to book tickets and to purchase different things online. There are a lot of different sites for pupils, students, gardeners, engineers, bankers, people who are fond of music, cinema, sports and even for disabled people. What is more, the Internet has revolutionized the way people communicate. Sending electronic text messages is much faster and easier than writing letters. People use email to stay in touch with friends worldwide.
However, there are still a lot of people who think that the Internet has too many disadvantages. Internet-addiction is a topical problem nowadays. Spending much time in front of the screen becomes a kind of obsession for many people. The symptoms of Internet addiction include sleep deprivation, decreased physical activity and social interaction with others. People who spend most of their time in the virtual world forget about the real one. They neglect their relatives and ruin their families. Besides, there is a lot of rubbish online and you can't always trust what you read on the web.
To sum up, the Internet becomes dangerous when it is misused. But if it is used wisely and moderately, it helps you work, study or entertain and saves plenty of time.
Internet dating is becoming more and more popular. However, many people say that meeting people online is dangerous.
Nowadays a lot of young people feel that meeting people online is just the same as meeting in a bar. Many of them make friends online and even fall in love with their virtual interlocutors.
To my mind, it is silly to trust a person you have never seen. You can never be sure that you communicate with the individual whose personal information and photos you see. For example, a "young" boy may turn out to be a 50-year-old man. Besides, it is very dangerous to give detailed personal information to complete strangers. Your online friend may be a swindler or even a murderer. So meeting such a person in real life may be extremely risky.
On the other hand, some people say that internet dating has many advantages. Firstly, it is easier for shy people to chat through a keyboard than face to face. Secondly, you can search the Internet when you are not busy. Besides, you can talk to lots of people at the same time and you can have several online boyfriends or girlfriends. One can list all his or her romantic requirements and then find exactly what he or she wants. But I still believe that face-to-face dating is much better.
To sum up, internet dating may help you find love. If you don't meet someone in real life, it seems a great alternative. But Internet daters must be cautious because you never know what you are going to get from online romance.
Various social networks have aroused great interest among Internet users. However, some people say that they have a lot of drawbacks.
Social networks are very popular among users of different ages and professions. But many people are concerned about the influence of social networks on their lives.
Personally, I think that social networks have a lot of benefits. Firstly, they link together users of the Internet who have common interests and give people an opportunity to look for old and new friends, to build communities, to send messages and to share news and pictures. There are other sites which allow classmates from school or university to keep in contact with each other. Secondly, many people use social networks to communicate and exchange personal information for dating purposes. Thirdly, social networks are being used by teachers and students. Teachers often help pupils with homework and post assignments, tests or quizzes. Social networks also serve to foster teacher-parent communication. Parents can ask questions without having to meet teachers face to face. Finally, some people search for job opportunities with the help of social networks.
However, some users are worried about data theft and viruses. The problem is that many people give out too much personal information that may be passed to third parties for different purposes. To protect user privacy, social networks allow users to choose who can view their profile or contact them. This prevents unauthorized users from accessing, adding, changing, or removing personal information and pictures.
To conclude, the popularity of social networks continues growing because more and more people find it easier to communicate digitally. What is more, millions of people use them for fun as well as for business and educational purposes.
Artificial intelligence performs quite a lot of jobs nowadays. However, many people are worried about computers doing the same things that people can do.
In the 90s and early 21st century artificial intelligence achieved its greatest success. Today clever machines are taught to think and make decisions. But is it safe that artificial intelligence is invading the world?
To my mind, computers and robots are very helpful. There are more and more jobs which humans leave to robots such as exploring another planet, defusing bombs or just doing boring household chores like cleaning. Computers can perform a lot of functions: they can control cars and planes, give us the news or compose music. Many factory jobs are performed by industrial robots nowadays. It has led to cheaper production of various goods, including automobiles and electronics. Artificial intelligence has successfully been used in a wide range of fields including medical diagnosis, stock trading, robot control, law, scientific discovery and toys.
However, there are some reasons to worry about robots. Firstly, the use of robots in industry leads to unemployment as many jobs are performed by machines. Secondly, industrial robots can be dangerous and cause harm to human workers. Besides, many people fear that highly intelligent robots may take over and destroy the human race. There are a lot of books and films about people losing control over clever machines that begin to kill their creators. But I believe that it is early to worry because robots are still clumsy and not very intelligent.
To conclude", artificial intelligence serves to help people and make their lives easier. That is why I think that we should promote research in artificial intelligence. But people must be careful and pay more attention to security.
Some people think that science plays the most important role in the development of our civilization; others believe that our world would be impossible without poetry.
What does science have in common with poetry? Science is a product of people's intellect. Poetry is a product of their imagination and inspiration. Science deals with bacteria, atoms, electricity, magnetic fields and so on. Poetry deals with human feelings such as love, jealousy, hatred and others.
I believe that the world wouldn't develop without science. The aims of science are making discoveries and increasing human knowledge and understanding. Science deals with such areas as the theory of evolution, the method of creation of the universe and the Earth, the origins of life and many others. Science has already helped people answer a lot of complicated questions. With the help of the latest achievements of science and engineering we can solve many problems and make our lives better.
However, many people are not sure that all we need is science. Some of them are convinced that our lives would be dull without poetry. People's feelings are so intense, that they want to express them using beautiful language. Poetry serves to stir our imagination and to evoke emotional or sensual responses. While reading poetry we forget about our problems and experience the poet's deepest dreams and fears. A good poem often makes us laugh or cry. It also makes us think about other people's feelings.
In conclusion, I'd like to say that it's rather difficult to live both without science and poetry. Science helps develop technology and solve many problems. Poetry helps make our lives more colourful and romantic. Besides, it helps us not to forget about human feelings, values and beliefs.
