Упражнение 2. A. Прочитайте текст и найдите слова или словосочетания, означающие portable, work, generate, at present.
Although most electricity comes from power stations, power
can also be generated by far smaller means. Nowadays, electricity
generators can be small enough to hold in the hand. A portable
generator can provide electricity no matter how far you are from
the mains (сеть). It works by turning the movement of a piston into
electrical energy. Such a generator can produce a 700 watt output,
enough to operate lights, television, and some domestic appliances.
Larger versions provide emergency power to hospitals and factories.

B. Найдите в тексте, приведенном в А, слова, означающие:
1. method, way
2. change, transform
3. principal wire to transmit electricity into a building
4. house
5. to be of no importance
6. much, considerably
7. situation needing action as soon as possible
8. power, energy produced
9. variant, form

I suppose everybody considers modern technologies to be significant in our everyday life.  Nowadays people can't imagine their lives without new devices.  They are everywhere in our everyday life.

Almost nobody washes the clothes by hand.  Almost everybody has a mobile phone. All modern offices are equipped with computers, scanners, printers, and other self-operating machines. The rapid rise of using the Internet is the reality of our time.

 But I think modern technologies can be dangerous to some extent for people because mankind becomes too dependent on them. We and our children depend on how 'clever' appliances work. But, it isn’t always healthy to use them for a long time. Sitting long hours in front of the computer is bad for the eyes and causes back problems. They say cell phones contain negative vibes that influence human organism.

Most people are sure that new technologies are good. Thanks to computers and the Internet we can find more educational resources in no time. Such electronic items as vacuum-cleaner, washing machine, microwave, dishwasher, blender and a lot of others have made our life easier. It's really true.  We can't but agree to it.  I am not against new technologies.  But in my opinion, nowadays the modern world relies too much on them.

In conclusion, I’d like to say that technological progress can be dangerous to some extent for humankind and for surrounding nature too. So it's necessary to make modern devices safer and cheaper for people to use them and make the people's life happier and more pleasant.
