«Science and 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 GPS 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.
