b/ wonderful scientific and technological inventions[?] and discoveries[?]

c/ science and technology making human life easier / electronics, information technology, medicine, telecommunication, transportation/

Mankind[?] has come a long way during its existence. In pre-historic times, people´s lives and their needs were simple – everything needed for life was at hand. People hunted[?] for food and made tools[?] from stones and simple clothes to protect them from cold.

Step by step, people started changing the world trying to make their lives easier and more comfortable[?]. They invented wheel and started transporting goods. They learnt to use water and wind for energy and built water and wind mills[?].

Important discoveries and inventions came in the 15th and 16th centuries – discovery of America, invention of the printing press[?], development in astronomy, medicine and biology. The industrial revolution[?] of the 18th and 19th centuries completely changed the world. It brought important inventions: the steam engine[?], the electric light bulb[?], the electric motor and the first petrol-driven car.

The development of science and technology went on rapidly and the 20th century brought such inventions as the airplane, the television, the computer, the mobile phone and the Internet. Research[?] in medicine brought new drugs and vaccines[?] that prolong[?] people lives. Antibiotics[?], x-ray[?], computer tomography (CT), laser surgery [?]and transplantation have improved [?]or even saved many lives.

Research in chemistry brought pesticides [?]and fertilizers[?] that enable us to plant more crops and new machinery helps to produce more food for the constantly growing population of the Earth.

At the beginning of the 3rd millennium, science and technology have deep influence[?] on our lives. They influence communication; we can talk to our friends or relatives in any part of the world using phones, satellites or computers. We can talk part in online chats and discussions. Internet banking and Internet shopping are becoming[?] more and more popular among people because they save our time and money. Travelling by plane has become more available [?]and distance can be overcome[?] much faster than ever before.

New technologies are everywhere, even surrounding[?] us at home. Our households are equipped [?]with modern appliances, such as refrigerators and freezers, vacuum cleaners, washing machines, dishwashers, microwave ovens, computers, TV sets, stereos, and DVD players. All these appliances and entertainment [?]equipment [?]have made our lives much easier and more comfortable than the lives of our great grandparents.
