英语翻译
Oil (油)is very useful to us .We need oil in many ways.Without oil the world will stop.Now oilmen look for oil in many places of the world.They look for it in deserts,in moutains and under the sea.Quite often they can find nothing,but their work goes on for many years.
Why is oil so important?Because our machines need it to run .People usually use big ships to carry oil.The ships carry it to everywhere.Maybe the oil in your car or motorbike comes from somewhere far away.Perhaps it comes from Iraq(伊拉克)or Venezuela(委内瑞拉).Many things need oil to work.Can give some examples?
