1. Have you ever stopped to think how your life would change if the world ran out of oil? Take a look at your day. The roof of your home is probably made waterproof by an oil product, bitumen. The same product is used for the road surface outside your home. Before you leave to go to work or school, just examine your surroundings. Is the room warmer than the cold air outside? Oil, or electricity from oil-fed generators may be keeping you comfortably warm. If you are comfortably cool in a tropical climate, your air conditioning unit may also depend on oil-fed generators. 1、你曾想过没有，如果世界上用尽了石油，你的生活会发生什么样变化呢?请看一看你的日常生活。你家的屋顶可能是用一种叫沥青的石油产品做成防水的。沥青同样可用来铺你家外面的路面。在你离家去上班或上学之前，请观察一下你周围的环境。房间里会比外面冷空气暖和吗?这是石油或由燃油发电机发出来的电使你感到舒适温暖。如果你在炎热的气候里感到舒适凉爽，那么你家的空调器可能也是靠燃油发电机工作的。 2. In the kitchen and the bathroom you will probably see some plastic fittings such as tiles and working surfaces; polystyrene cups; curtains made from synthetic materials; disinfectants and detergents. All owe their origin to the oil known as petroleum , found deep in the earth. Look inside the medicine cupboard for more petroleum products, medical paraffin and petroleum jelly. Cosmetics such as face creams, lipsticks and hair preparations are often based on petroleum. |
