答案

(1)A (1分); B (1分)

(2)谷地(1分); 背斜顶部受张力,岩石破碎,易被侵蚀,往往形成谷地。(2分)

山地(1分); 向斜槽部受挤压,岩性坚硬,不易被侵蚀,往往形成山地。(2分)

(3)A (1分);  背斜具有天然的穹形构造,结构稳固;背斜岩层向上拱起,地下水向两侧流,保持隧道干燥。(2分)

(4)C D(1分)

(5)A(1分);   B (1分)

题目分析:

(1)背斜岩层向上弯曲,符合的是A;向斜岩层向下弯曲,符合的是B。

(2)A处背斜成谷,成因是背斜顶部受张力,岩石破碎,易被侵蚀,往往形成谷地。

B处向斜成山,成因是向斜槽部受挤压,岩性坚硬,不易被侵蚀,往往形成山地。

(3)地下隧道应建在背斜处,原因是背斜具有天然的穹形构造,结构稳固;背斜岩层向上拱起,地下水向两侧流,保持隧道干燥。

(4)修建大型工程应避开断层。

(5)背斜是良好的油气储存构造;向斜是良好的地下水储存构造。

     Apple Inc co-founder and former CEO Steve Jobs, counted among the  greatest American CEOs of

his generation, died on Wednesday at the age of 56,  after a years-long and highly public battle with

cancer. Mourners gathered  outside his house in Palo Alto, California, and Apple stores around the world.

Steve Jobs has the Apple II, the Mac, the iPod, the iPhone, the iPad and Pixar.

     Steve Jobs was a college dropout. He was adopted by a machinist and his wife, an accountant,  They

supported his early interest in electronics. He and his friend Steve Wozniak started Apple  

Computer-now just called Apple-in 1976. They stayed at the company until 1985. That year, Steve  

Wozniak returned to college and Steve Jobs left in a dispute with the chief executive.

     Mr. Jobs then formed his own company, called NeXT Computer. He rejoined Apple in 1997 after  it

bought NeXT, He helped remake Apple from a business that was in bad shape then to one of the most

valuable companies in the world today. However, Steve Jobs stepped down as Apple's chief executive

in August, 2011 because of his health. He died a day after the company released a new iPhone version

that met with limited excitement. Steve left behind a company that only he could have built, and his spirit

will forever be the foundation of Apple.
