根据材料和图，结合所学知识，回答下列问题。

云南苍山洱海地区山清水秀、林茂粮丰，大理古城宛如一颗明珠镶嵌在青山绿水之间，人与自然和谐统一。  

（1）图中A地、B地的地貌分别为_______、_________ ，从内外力作用的角度分别说明它们形成的主要过程。

_________________________________________________________________________________________________________________。

（2）如果在洱海西岸大规模建设住宅，可能对地理环境产生哪些不利影响？

_________________________________________________________________________________________________________________。

答案

（1）断块山；洪积－冲积平原；内力作用形成断层，断裂面两侧岩体以垂直方向运动为主，A侧岩体相对上升，形成断块山；B侧岩体相对下降，形成谷地，同时流水等外力不断将风化、侵蚀产物搬运到谷地边缘堆积，形成洪积－冲积平原。

（2）占用耕地和湿地，影响农业生产，湿地的功能减弱、效益降低。人口增多，林地遭破坏，入湖污水增多，生物多样性减少，自然灾害增多，环境质量下降，不利于大理古城的保护，人地关系恶化。

A Talent Shortage Hits Green Start-ups


On May 1 applications closed for the first intake of a novel kind of executive-education programme. Set up by a bunch of venture-capital firms and other companies in New England, the three-month course will teach its "fellows" about renewable energy. To qualify for a fellowship, applicants must be successful entrepreneurs from other industries, such as IT or health care, and be zealous about profiting from greenery.
"A lack of talent, especially entrepreneurial talent, was one of the biggest bottlenecks to growth we identified in the clean-tech industry," says Peter Rothstein of Flagship Ventures, a venture-capital firm that is one of the programme’s founders. That bottleneck worries investors, who have been pouring cash into everything from solar energy to hybrid electric cars: last year global investment in renewable-energy businesses alone rose by 60%, to $148.4 billion, according to New Energy Finance (NEF), a research firm.
Although the prospect of minting money while helping to save the planet has attracted a stream of executives from other industries to clean-tech start-ups, few of them have much experience of their new field. In a recent global survey of 75 senior executives involved in clean-tech firms conducted by NEF and Heidrick & Struggles, a headhunter, over 90% cited top-level recruitment as a serious concern.
Counting on converts from other industries is risky, because some of the skills needed to run clean-tech companies are very different from those required to, say, launch a website. For one thing, the bosses of renewable-energy start-ups need to understand enough about the science to be able to pluck scientists from obscurity. For another, they need a grasp of project-financing techniques for costly prototype power plants. They also need to be able to deal with capricious regulatory and fiscal regimes. "If you’ve never done anything in the energy space, it can be intimidating,"says Bill Davis, the boss of Ze-gen, a start-up that generates electricity from waste.
Hence the New England bootcamp’s goal of helping 25 aspiring green entrepreneurs a year to make the transition. As well as giving them an overview of the latest scientific research, the course also includes sessions on project finance and government regulations.
Start-ups also face a battle for engineers and scientists. And as small firms take advantage of a growing enthusiasm for greenery in East Asia and the Middle East, they also need more staff with international experience. Tracking down such rare pearls can be a distraction for busy bosses.
Ann Cormack, the head of DI-BP Fuel Crops, a firm based in London that develops crops for biodiesel, reckons talent-spotting takes up about a fifth of her time. She has spent several months hunting for an agronomist, for instance, to no avail.
Like the bosses of many other clean-tech firms, Ms Cormack is using headhunters. They like the clean-tech business because wages, on which their commissions tend to be based, are rising fast. Not so long ago, executives would do meaningful green jobs for menial pay. But in recent years, wages have soared as the industry has grown and attracted big utilities and private-equity firms. Now what matters to the geeks is a different kind of green. "Good people can set their own price tag," says one recruiter, "and they want jam tomorrow, not in five years." It looks like they’ll get it.

What does the expression "a different kind of green" (Line 5, Last Para.) refer to

A. Salaries.
B. Commissions.
C. New employees.
D. Renewable energy.
