unit 1 Sources of Energy

1、Unit 1Sources of EnergyListen to thisQuestions:1. What does petroleum mean in Latin?2. What are the sour oil and sweet oil?3. What made oil popular?4. When was the first oil well drilled? 5. When was Standard Oil formed? And whats its business?Ans:Rock oil.Sour oil contains a lot of sulfur and sweet

2、 oil is low in sulfur and often more valuable. A method was found to make kerosene fuel from petroleum, which became popular for heating and lighting. In 1859.By 1870, Rockefeller and his partners formed the Standard Oil Company. Standard Oil and other companies that it owned performed every level o

5、sedimentary rock: 1) layers of sandy or clayey rock (strata); 2) tends to split along layers; mostly brown or gray; 3) may have fossils and water or wind marks. The beauty of sedimentary rocks is that their strata(地層) are full of clues to what the past world was like. Those clues might be fossils, m

6、arks left by water currents or more subtle features seen under the microscope or in the lab. From these clues we know that most sedimentary rocks are of marine origin, usually forming in shallow seas. But some sedimentary rocks formed on land which are called continental or terrigenous（陸源） (land-for
