1) The picture shows a street of terraced houses in a city. I don't know where it is exactly. Perhaps it is in Germany, but it is probably in Britain orIreland somewhere. The houses are quite small and they haven't got front gardens. But some houses look very colorful. Перевод: Картина показывает улицу таунхаусы в городе. Я не знаю, где именно. Возможно, он находится в Германии, но это, вероятно, в Великобритании илиИрландия куда-то. Дома довольно мало, и они не получили палисадники. Но некоторые дома выглядят очень красочные. 2) Oh, and there is someone washing his car in the background. - На переднем плане есть некоторые маленькие дети, которые играют в футбол на улице 3) It is not a very beautiful street, but the atmosphere seems very friendly and relaxed. - Это не очень красивая улица, но атмосфера, кажется, очень дружелюбны и расслаблены. 4) The houses are quite small and they haven't got front gardens. But some houses look very colorful. In the foreground there are some young kids who are playing football in the street. And there are two old men on the right who are chatting to each other in front of one of the houses. Perhaps they are gossiping about the neighborhoods. Oh, and there is someone washing his car in the background. It is not a very beautiful street, but the atmosphere seems very friendly and relaxed. - Домов довольно мало, и они не получили палисадники. Но некоторые дома выглядят очень красочными. На переднем плане есть некоторые маленькие дети, которые играют в футбол на улице. И есть два старики справа, которые, болтая друг с другом перед одним из домов. Возможно, они сплетничают о кварталах. Ох, и есть кто-то моет машину в фоновом режиме. Это не очень красивая улица, но атмосфера, кажется, очень дружелюбной и расслабленой. Why? I think the author would show us that not only external beauty plays an important and "beautiful" role in life, but also internally. - Почему? Думаю автор хотел показать нам что не только внешняя красота играет важную и "красивую" роль в жизне, но и внутреняя.
Plastics are non-metallic, synthetic, carbon-based materials. They can be moulded, shaped, or extruded into flexible sheets, films, or fibres. Plastics are synthetic polymers. Polymers consist of long-chain molecules made of large numbers of identical small molecules (monomers). The chemical nature of a plastic is defined by the monomer (repeating unit) that makes up the chain of the polymer. Polyethene is a polyolefin; its monomer unit is ethene (formerly called ethylene). Other categories are acrylics (such as polymethylmethacrylate), styrenes (such as polystyrene), vinys (such as polyvinyl chloride (PVC)), polyesters, polyurethanes, polyamides (such as nylons), polyethers, acetals, phenolics, cellulosics, and amino resins. The molecules can be either natural — like cellulose, wax, and natural rubber — or synthetic — in polyethene and nylon. In co-polymers, more than one monomer is used.The giant molecules of which polymers consist may be linear, branched, or cross-linked, depending on the plastic. Linear and branched molecules are thermoplastic (soften when heated), whereas cross-linked molecules are thermosetting (harden when heated).Most plastics are synthesized from organic chemicals or from natural gas or coal. Plastics are light-weight compared to metals and are good electrical insulators. The best insulators now are epoxy resins and teflon. Teflon or polytetrafluoroethene (PTFE) was first made in 1938 and was produced commercially in 1950.Plastics can be classified into several broad types.1. Thermoplastics soften on heating, then harden again when cooled. Thermoplastic molecules are also coiled and because of this they are flexible and easily stretched.Typical example of thermoplastics is polystyrene. Polystyrene resins are characterized by high resistance to chemical and mechanical stresses at low temperatures and by very low absorption of water. These properties make the polystyrenes especially suitable for radio-frequency insulation and for parts used at low temperatures in refrigerators and in airplanes. PET (polyethene terephthalate) is a transparent thermoplastic used for soft-drinks bottles. Thermoplastics are also viscoelastic, that is, they flow (creep) under stress. Examples are polythene, polystyrene andPVC.2. Thermosetting plastics (thermosets) do not soften when heated, and with strong heating they decompose. In most thermosets final cross-linking, which fixes the molecules, takes place after the plastic has already been formed.Thermosetting plastics have a higher density than thermoplastics. They are less flexible, more difficult to stretch, and are less subjected to creep. Examples of thermosetting plastics include urea-formaldehyde or polyurethane and epoxy resins, most polyesters, and phenolic polymers such as phenol-formaldehyde resin.3. Elastomers are similar to thermoplastics but have sufficient cross-linking between molecules to prevent stretching and creep.
