Task 1

1. Both the metals and the polymers can be alloyed.

2. It is possible to develop polymeric substances with the scheduled properties.

3. The so-called "aging" of the polymers is due to chemical and physical changes caused by the effect of light, heat and humidity.

Task 2

1. Polymers are characterized by their viscosity colour and softening points.

2. The properties of the polymers depend on their super-molecular structure.

3. The main concern of researchers and engineers is to improve the quality of mass produced goods.

Task 3

1. Polymers are widely used in industry.

2. Light, heat and humidity affect the polymers.

3. The main concern of the researchers and engineers is to improve the quality of polymers.

Голландцы были первыми европейцами,посетившими Австралию. Многие мореплаватели попадали на западный берег Австралии. Но голландцы точно не знали,на сколько простирается страна в восточном направлении,и потому в 1642 году капитан Абель Тасман был послан,дабы выяснить,как далеко восток. Тасман заплыл слишком далеко на юг и не увидел континент,но зато обнаружил остров,названный Тасманией в его честь. 
Никаких тщательных исследований континента в течение века не проводилось. И только в 1770 году капитан Джеймс Кук назвал его Новым Южным Уэльсом и отрапортовал обратно в Англию,что большая часть материка выглядит пригодной для заселения. В Лондоне британское правительство посчитало,что это хорошее место для ссылки преступников. В мае 1787 года первая группа заключенных и несколько солдатов (11 кораблей и 500 человек) прибыли в Австралию из Англии. Для первых переселенцев жизнь была тяжела. Колонисты в обеспечении едой и другими принадлежностями во всём зависели от английских кораблей. Заниматься сельским хозяйством было трудно. Это было в то время,когда люди начали разводить прекрасных овец-мериносов ради шерсти. Позднее шерсть стала важной индустрией. Многие заключённые освободились и остались в Австралии. Многие свободные английские поселенцы видели возможности континента: в начале 19 века были основаны несколько свободных колоний. Шесть наиболее ранних выросли и стали штатами современной Австралии: Новый Южный Уэльс,Виктория,Квинсленд,Южная Австралия,Западная Австралия и Тасмания (островной штат). Независимые колонии вскоре поняли потребность совместных действий в определённых вопросах: они поняли,что нужно объединяться. Конституция была написана и одобрена Британской короной,и 1-ого января 1901 года шесть отдельных колоний стали штатами нового Австралийского союза.
