Question

   In 1769,William Smith was bom in a little town in Oxfordshire,England. He received basic village schooling but mostly he wandered on his uncle's farm collecting the fossils in the rocks of the Cotswold hills. When he grew older Smith learned surveying from books and at 18 he learned from a local surveyor. He then began to teach himself geobgy (地質(zhì)學(xué)) .

   When he was 24 ,he went to work for the company that was digging the Somerset Coal Canal in the south of England. This job gave Smith an opportunity to study the fresh strata created by the newly dug canal. He later worked on similar jobs across England all the while studying strata and collecting all the fossils he could find. Smith used mail coaches to travel 10 ,000 miles per year. In 1815 he published the first modem geological map UA Map of the Strata of England and Wales with a Part of Scotland”.

   In 1831 when Smith was recognized by the Geological Society of London as the “father of English geology”，it was not only for his maps but also for something even more important. People had hoped strata could be used to calculate geological time,but scientists found the sequences（順序） of rocks sometimes differed from area to area and that no rock type was ever going to become a dependable time marker. Even without the problem of regional differences,rocks present a difficulty as unique time markers. Quartz （石英) is quartz; there's no difference between two-million-year-old quartz and quartz created over 500 million years ago.

   As he collected fossils from strata,Smith noticed the fossils told a different story from the rocks. Particularly in the younger strata the rocks were often so similar that he had trouble distinguishing the strata,but he never had trouble telling the fossils apart. Some fossils appear in many strata,but others occur only in a few strata,and a few species had their births and extinctions within one particular stratum. Fossils are thus identifying markers for particular periods in Earth's history.

   B. Talented and productive.

   C. Warm-hearted and honest.

   D. Hard-working and devoted.

30. The author mentions quartz to show that .

   A. no rock can be a reliable time marker

   B. no quartz can be found in recent times

   G. quartz can fell people rocks,geological time

   D. the sequences of rocks differ from area to area

31. Which of the following is Smith's greatest achievement?

   A. He drew many maps of strata.

   B. He used fossils to identify strata.

   C. He built a lot of canals in England.

   D. He was the creator of modem geology.

(個(gè)人情況)

本文是記敘文。文章介紹了英國地質(zhì)之父。

28. B.細(xì)節(jié)理解題。由第一段的but mostly he wandered on his uncle,s farm collecting the fossils in the rocks of the Cotswold hills 可知，史 密斯小時(shí)候?qū)Φ刭|(zhì)學(xué)產(chǎn)生了濃厚興趣。

29. D.推理判斷題。由第二段的He later worked on similar jobs across England all the while studying strata and collecting all the fossils he could find. Smith used mail coaches to travel  10.000 miles per year可知，史密斯勤奮而專注地 進(jìn)行科學(xué)研宂。

30. A.推理判斷題。由第三段可知，作者提到石英 是為了舉一個(gè)例子，用來支持no rock type was ever going to become a dependable time marker 或 rocks present a difficulty as unique time markers這個(gè)觀點(diǎn)。

31. B.細(xì)節(jié)理解題。由最后兩段，特別是文章最后 —句 Fossils are thus identifying markers for particuar periods in Eartfi’s history 可知，史密斯 的這錢成就中，用化石鑒定巖層是最重要的成 就。
