Unformatted text preview: cing for a local surveyor ○Smith’s family lived in a small English town and possessed little wealth在 ○Smith learned about fossils from books he borrowed from his uncle 在 209 Mail@liuwenyong.com 在在在在在在 www.liuwenyong.com 在在在在在在在在在在在在在在在,在在在在在在在在在在 ○Smith eventually left his village to work on the excavation of an English canal. Paragraph 2: 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 在Smith used mail coaches to travel as much as 10000 miles per year 在 In 1815 he published the first modern geological map “A Map of the Strata of England and Wales with a Part of Scotland”, map so meticulously researched that it can still be used today在 3. Which of the following can be inferred from paragraph 2 about canal building? ○ Canals were built primarily in the south of England rather than in other regions 在 ○ Canal building decreased after the steam locomotive was invented在 ○ Canal building made it difficult to study rock strata which often became damaged in the process 在 ○ Canal builders hired surveyors like Smith to examine exposed rock strata在 4.Accordingto paragraph2在which of the following is true of the map published by William Smith? ○It indicates the locations of England's major canals ○It became most valuable when the steam locomotive made rail travel possible ○The data for the map were collected during Smith’s work on canals ○It is no longer regarded as a geological masterpiece 5. The word meticulously in the passage is closest in meaning to ○carefully ○quickly ○frequently ○obviously Paragraph 3: In 1831 when Smith was finally recognized by the Geological Society of London as the “father of English geology”, was not only for his maps but also for something even more important 在 Ever since people had begun to catalog the strata in particular outcrops, there had been the hope that these could somehow be used to calculate geological time 在 But as more and more accumulations of strata were cataloged in more and more places, it became clear that the sequences of rocks sometimes differed from region to region and that no rock type was ever 在 going to become a reliable time marker throughout the world Even without the problem of regional differences, rocks present a difficulty as unique time markers Quartz is quartz—a silicon ion surrounded by four oxygen ions— there’s no difference at all between two­million­year­old Pleistocene quartz and Cambrian quartz c...
