UNIT 2

Technical Progress

Text A: The role of technical progress

Read and translate the text.

The scientific and technical revolution has changed our life very much.

 

The computers, the mobile phones and other digital devices have entered our everyday life.

 

The atomic, space and energy age was followed by the age of computers. The tasks which had seemed eternal before have been solved one by one by computers. During the last decade many fundamental changes occurred because of electronic devices. It is even difficult to imagine the social and economic consequences of the microelectronic revolution.

 

The large use of computers has influenced our life in such a way that it was difficult to imagine 15 or 20 years ago. On the one hand, computers have simplified our life greatly. If you typed a text on the typewriter and made a mistake you had to type the whole page again. Making several copies of the same document used to be a difficult job too. But now it‘s quite different. Correcting mistakes is easy. Computer also helps us to buy goods, find information, book tickets, make presentations and annual reports, and make difficult calculations. Time is saved for leisure.

 

Leisure time is also influenced by computer and other periphery devices. You no longer go to the music shops – many things are available on the internet. You needn‘t write letters to your relatives or friends – you can send an e-mail. And your photo albums are on computer too. Computer games are probably also a part of your free time. They became more and more realistic and complicated, and for many people it becomes impossible to tear themselves away. This means that electronic devices, such as computer and TV set are used mostly for entertainment and consume most of the time that could be spent on work, going for a walk and sleeping. Man becomes a slave of devices which were designed to make him stronger.

 

Is there a way out? In fact, there is, but many people don`t know it and are still slaves. The best decision is not to give these equipments place in your heart. They should do their work. And when you have a rest, prefer real communication to virtual one and living an active life to watching films about crime. Then electronics will be not our lord or enemy but our friend!

Text B: Sun Powers Cars

Read and translate the text.

 

Each day, millions of people across the world fill their cars with gas1to make them move. But can you imagine2running a car on just a tank full of sunshine3! That's what some college students did this pastsummer in the U.S.

The students built cars for an unusual race4 called "Sunrayce USA". The students had to drive their cars from Florida to Michigan, more than 1,600 miles, in the fastest time. The only power5 their cars used was solar power, or energy from the sun.

The students' solar-powered cars were different from any gas-powered car on the road today. Here's how.

The outside6 of the solar cars was covered with rows7 of dark, shi-ny8 panels9made of special materials. These panels caught the sun'srays and turned sunshine into electricity that powered the cars' motors. The panels also saved10 solar power in special batteries so the cars could run on cloudy11 days.



The solar cars were much lighter12 than gas-powered cars. Their tires13were as thin as bicycle tires. Some race cars14had parts made ofthe plastic material used in drinking cups.

The cars had to be light because their motors didn't have as much power as cars with gas-powered motors. Each car ran on about the same amount of energy needed to run a hair dryer15!

The cars were also built in strange shapes16. One car looked like a giant pizza box with a bubble17 on the top. Another was shaped like a teardrop18. These shapes helped air pass smoothly19over and aroundthe cars so they could move easily along the rode. Will people be able to buy solar cars soon? Most scientists say no. But scientists hope the race will help them learn new ways to build cars that are lighter in weight20and use less fuel.
