问题 单项选择题

下列景观的发展演变过程,体现出地貌的什么发育过程?()

A、冲积平原

B、断块山

C、背斜成谷

D、背斜成山

答案

参考答案:C

解析:【分析】本题考查地质构造与构造地貌。地质构造分为:皱褶(背斜、向斜)和断层。皱褶形成的地形一般为:背斜成山;向斜成谷。倒置的地形:背斜顶部受到张力被侵蚀成谷地;向斜槽部受挤压岩性坚硬不易被侵蚀反而成山岭。断层上升岩块成山岭或高地(华山、庐山、泰山),下降岩块(地堑)成谷地或低地(渭河平原、汾河谷地)。图中反映了背斜成谷,向斜成山。所以本题选择C选项。

London taxi drivers know the capital like the back of their hands. Just  36  into one of the city’s 22,000 distinctive (有特色的)shaped cars and tell the driver your  37 . No matter how small and obscure (模糊的) the street is,  38  will be able to get you there without any  39 .

The reason London taxi drivers are so  40  is that they have all gone through a very rough training period known as “the knowledge” to get the special license (许可证) 41  to drive taxis. During this period,  42  can take from two to four years, the would-be taxi driver  43  learn the most  44  route to every single road and to every important building in London. To  45  this, most learners go around the city  46  small motorbikes, practicing how to move to and from different points of the city.

Going around London on a small motorbike can have its problems, particularly during the winter. Collin Sinclair, 40, who has been a taxi driver for 15 years, described his  47  period as a time of  48 , sweat and tears. “There was thick snow everywhere and I had to  49  my mother’s tights (紧身裤) because I was so cold,” he said.

Learner taxi drivers  50  several times during their training period  51  government officers. Sinclair thought his exams were a nerve-racking (伤脑筋的) experience. “The officers  52  you, ‘How do you get from Buckingham Palace to the Tower of London?’ and you have to take them there in a very direct line. When you get to the Tower, they  53  say, ‘Well done.’ They will quickly  54  the next question. After five or six questions, they’ll just say, ‘See you in two months time,’ and  55  you know the exam is over.”
