This was before the steam locomotive, and canal building was at its height. The companies building the canals to transport coal needed surveyors to help them find the coal deposits worth mining as well as to determine the best courses for the canals. This job gave Smith an opportunity to study the fresh rock outcrops created by the newly dug canal. He later worked on similar jobs across the length and breadth of England, all the while studying the newly revealed strata and collecting all the fossils he could find. Smith used mail coaches to travel as much as 10,000 miles per year. In 1815 he published the first modern geological map, "A Map of the Strata of England and Wales with a Part of Scotland," a map so meticulously researched that it can still be used today.

Which of the sentences below best expresses the essential information in the highlighted sentence in paragraph 3? Incorrect choices change the meaning in important ways or leave out essential information.

A．The discovery of regional differences in the sequences of rocks led geologists to believe that rock types could some day become reliable time markers.

B．Careful analysis of strata revealed that rocks cannot establish geological time because the pattern of rock layers varies from place to place.

C．Smith"s catalogs of rock strata indicated that the sequences of rocks are different from place to place and from region to region.

D．Because people did not catalog regional differences in sequences of rocks, it was believed that rocks could never be reliable time markers.

Watts steam engine soon showed what it could do. It liberated industry from dependence on running water. The engine eliminated water in the mines by driving efficient pumps, which made possible deeper and deeper mining. The ready availability of coal inspired William Murdoch during the 1790s to develop the first new form. of nighttime illumination to be discovered in a millennium and a half. Coal gas rivaled smoky oil lamps and flickering candles, and early in the new century, well-to-do Londoners grew accustomed to gaslit houses and even streets. Iron manufacturers, which had starved for fuel while depending on charcoal, also benefited from ever-increasing supplies of coal; blast furnaces with steam-powered bellows turned out more iron and steel for the new machinery. Steam became the motive force of the Industrial Revolution, as coal and iron ore were the raw materials.

In paragraph 3, the author mentions William Murdochs invention of a new form. of nighttime illumination in order to

A．indicate one of the important developments made possible by the introduction of Watt"s steam engine

B．make the point that Watt"s steam engine was not the only invention of importance to the Industrial Revolution

C．illustrate how important coal was as a raw material for the Industrial Revolution

D．provide an example of another eighteenth-century invention that used steam as a power source

听力原文：G : Hello !

M : May I speak to Mr. Golden ,please?

G : Yes, I am Golden.

M : Good morning, Mr. Golden. This is Mary Thomson from Business Weekly. I want talk with you about 3M’s intrapreneurship. Could you introduce it to our viewer?

G : Ok! We took advantage of the 3M policy that allow scientist to spend up to 15% their time on project of their own choosing.

M : Could you tell me more about the policy?

G : Of course, this policy dates back to 1923, when 3M’s chief executive William Mcknight discovered Dick Drew working on the tape project that he’s been ordered to abandon. Recognizing the people do their best work on projects that interest them, McKnight didn’t stop Drew. How wise he was! The project Drew wouldn’t give up produced the transparent tape that most of us know as Scotch tape. Since then, 3M has established a corporate culture that encourages teamwork but also stresses individualism.

M : This is really a great story of 3M corporation.

You will hear a news reporter A is making phone interview with B concerning this intrapreneurship.
