Условие.

A Read the introduction below. Then look at your clothes. What fabrics and substances are you wearing? Are any of your clothes ‘special’, eg waterproof, quick dry or no-wrinkle?

acrylic • canvas • cotton • glass
leather • nylon • plastic • polyester
rubber • silicon • silk • viscose • wool

Science and technology have entered our lives in ways we don't even realize. Simple chemistry is one element of science that has changed our lives. Take clothes, for example, and look at how chemistry has changed our choices.

Once, clothes were only made of natural fibres like cotton, silk or wool. Then, thanks to organic chemistry, we discovered synthetic or artificial fibres like nylon, polyester, acrylic and viscose. What are you wearing? Are your clothes made of natural fibres, or synthetic, man-made fibres? They're probably a mixture of both.

Now think about the kind of clothes you can get that make life more convenient. There are clothes that do not need ironing, which you can't stain and that keep you dry from the outside and dry from the inside. This is all chemistry. But how does it work?

Решение.

Решение 2.

Прочитайте введение ниже. Затем посмотрите на свою одежду. Какие ткани и материалы вы носите? Есть ли у вашей одежды что-то 'особенное', например, водонепроницаемость, быстрая сушка или отсутствие складок?

Ответ:

I am wearing a T-shirt and jeans. My T-shirt is mostly cotton, and my jeans are a blend of cotton and a little bit of polyester for stretch. I also have socks on, which are probably cotton with some synthetic fibres. My clothes are not special like waterproof or quick-dry; they are just regular everyday clothes.

На мне футболка и джинсы. Моя футболка в основном из хлопка, а джинсы — это смесь хлопка и немного полиэстера для эластичности. На мне также носки, которые, вероятно, хлопковые с добавлением синтетических волокон. Моя одежда не особенная, не водонепроницаемая и не быстросохнущая; это просто обычная повседневная одежда.
