Polymers

Переведите письменно текст с английского языка на русский, обращая внимание на герундий.

Researchers are being carried out at modifying known polymers with the purpose of developing in them desired properties. By combining molecules of several polymers we obtain polymers with new properties non-existent in any of the known synthetic materials.

Scientists succeeded in developing means of obtaining a synthetic rubber with properties similar to those of natu­ral rubber.

Plastics will occupy an important place in any branch of industry. There will be large but extraordinary light ships made of plastics and totally resistant to corrosion by sea water. The product of oil-producing countries will no longer be transported across the seas in huge tankers, but in strong reservoirs possessing light- and thermo-resistant properties. There will be spaceships made of polymers withstanding high temperatures and cosmic radiation.

Farmers will forget the primitive method of protecting the seeds from frost with bonfire smoke. Better protection against low temperature will provide light-resistant polymer sheets allowing ultra-violet rays to penetrate through them.

Huge wooden framework will no longer be erected for repainting a building. New coatings on houses resistant to light, heat and atmospheric oxygen will change the aspect of towns. Houses built of polymers will be both more durable and cheaper, than those built of brick and concrete. Metal working industry will be entirely transformed. Precision cast units made in polymer moulds will radically decrepit the necessity for finishing parts mechanically. The problem of synthesizing natural polymers, including proteins, is a major task, one of the greatest biological and econom­ical importance.

Its solution will probably require long, concentrated and joint efforts by scientists in various fields.

A Robot's Best Friend

Tired of walking your dog and finding its hair every­where? Sony's robotic dog, AIBO, may be for you.

AIBO is a totally autonomous robot capable of hearing and seeing, sensing balance and touch. Eighteen specialized motors allow such dog-like motions as rolling over, scratching, playing dead, and chasing a pink ball.

Like a puppy, with time and training AIBO devel­ops perfect movements and unique behaviour patterns, Programmed to seek companionship, AIBO simulates emotions like happi­ness, surprise, and anger and is clever at responding verbal commands.
