7)Modern technologies

Although many people blame technology for destroying nature and causing pollution, and say that it is the worst evil in the world , I still believe that it has greatly changed our lives for the better as we hardly imagine what would happen if we went for a day without technology. Technology is very popular in our daily life thanks to its advantages. As we know, firstly, technology in household helps people do the housework. For example, housewives do not need to wash manually, but they can use washing machine. Another reason why I advocate the viewpoint that technology has made the world a better place to live is that it makes the world smaller. Nowadays people can travel faster and easier to other places by car, bus and air-plane, and see many new interesting things around the world. In addition, they communicate with people in different countries through the Internet and phones, which saves them lots of time and money. But the most worthwhile benefit technology has brought to us is that it makes us healthier and happier. Clear progress in medicine, use new technologies to diagnose and combat diseases make therapy more effective. It allows us to cure serious diseases such as cancer and cardiopathy. Statistics show that life expectancy is getting longer. In Europe, for example, today life expectancy has climbed past 80 and people are glad to be alive; the longer they live in good health, the happier they feel they are. So, as we go forward into this ‘magical future’, will technology make the world a better place to live? Experts say it will!

8)The application of electronics in everyday life

Electronics is a field of engineering and applied physics deal­ing with the design and application of electronic circuits. The operation of circuits depends on the flow of electrons for gen­eration, transmission, reception and storage of information.

Today it is difficult to imagine our life without electronics. It surrounds us everywhere. Electronic devices are widely used in scientific research and industrial designing, they control the work of plants and power stations, calculate the trajectories of space-ships and help the people discover new phenomena of nature. Automatization of production processes and studies on living organisms became possible due to electronics.

Wireless internet is becoming more common all the time, with laptops set up in cyber cafes where people can drink coffee and check their email all at the same time. The computer user can do all the web searching in relative privacy thanks to the electronic accessories which can be added to the computer. Conversely, more and more transactions are being sent electronically across the airwaves so security is becoming a larger issue than ever before. Merchants who sell products online must be able to assure their customers that information submitted at a website is not being accessed by unauthorized personnel.

Music is a prime user of electronics, both in recording and in playback mode. Stereos, record players, tape decks, cassette players, CD drives and DVD players are all the result of advances in electronics technology in the last few decades. Today people can carry a playlist of hundreds of songs around with them easily in a very small device--easily portable. When you add Bluetooth or headphones the music can be heard by the user, but does not disturb those nearby.

Electronics technology in cameras has increased dramatically. A digital camera is available to most Americans at a price they can afford and cellphones often includes a fairly sophisticated digital camera that can capture still pictures or even video pictures and store them or transfer them to a computer where they can be saved, shared digitally with family or friends or printed out in hard form with a photo printer device. Pictures obtained through a camera or by means of a scanner can be edited, cropped, enhanced or enlarged easily through the marvel of electronics.

Literally thousands of everyday devices that we use constantly make use of electronics technology in order to operate. These are products ranging from automotive engines to automated equipment in production settings. Even artistic efforts benefit from computer modeling prior to the committing of valuable artistic media to create the finished product.

Electronics devices are being used in the health field, not only to assist in diagnosis and determination of medical problems, but to assist in the research that is providing treatment and cures for illnesses and even genetic anomalies. Equipment such as MRI, CAT and the older X-rays, tests for diabetes, cholesterol and other blood component tests all rely on electronics in order to do their work quickly and accurately. Pacemakers and similar equipment implanted in the body is now almost routine.
