(1)图中设计修建从B村到A村公路的 ①和②两个线路方案中,   较为合理,理由是                                  。(3分)

(2)修建从B村到D村的公路不走直线, 而绕道C村的主要原因是         

                                                       。(2分)

(3)因发展需要,该地拟建一人工运河以沟通Ⅰ、Ⅱ两条河流。请在图中用“〓”画出运河开凿的最佳位置,并说明理由。(5分)

答案

(1)②(1分)  地势平坦,工程量小、建设成本低(2分)。

(2)方便C村居民出行,增加线路货、客流量,提高经济效益(2分)

(3)如下图(2分)在该位置开凿,运河的里程短,工程量小,工程造价低(3分)

题目分析:(1)山区的道路应避开陡坡,而呈之字型分布,故②线路符合。(2)从经济效益方面考虑,经过C村可增加运量。(3)开凿人工运河,应考虑线路长短,即工程量,应从两河之间的最短距离位置开凿。

点评:本题难度低,学生只要掌握地形、线路长短等自然因素和社会经济因素对交通线建设的影响即可判断,注意比较分析。

单项选择题

No blueprint exists for transforming an economy from one with a great deal of government control to one based almost solely on free market principles. Yet the experience of the United Kingdom since 1979 clearly shows one approach that works: privatization, in which under-performing state-owned are sold to private companies.

By 1979, the total amount of debt, liabilities, and losses for state-controlled enterprises in the UK topped 3 billion annually. By selling off many of these companies, particularly those in the depressed industrial sector, the government decreased its debt burden and ceased pumping public funds into money losing enterprises. According to government spokesperson Alistair McBride, "Far from past practice of throwing good money after bad, the Queen’s government this year expects to take in 34 billion from the proceeds of the sale." That, say some analysts, may only be the beginning. Privatization has not only been credited with rescuing whole industries but the nation’s economy to boot.

Due to increased tax revenues from the newly privatized companies along with a rebound in the overall economy, economic forecasters predict that Britain will be able to repay nearly 12.5% of the net national debt within two years. That is good news indeed for the economy as a whole at a time when many sectors are desperate for any ray of sunshine. British Airways this week announced a 20% jump in overall ticket sales and profits over this quarter a year ago. British Gas announced its first profitable quarter in nine years. At Associated British Ports, a new labor contract was finalized, the first union contract signed at the port without a work stoppage in twelve years. Closer to home for most Britons, the nation’s phone service, British Telecom, no longer puts new subscribers on a waiting list. Prior to privatization, new customers would sometimes have to wait months before phone service could be installed in their home. Now, according to a company press release, British Telecom is promising 24-hour turnaround for all new customers.

Part of this improved productivity has to do with new efforts to allow employees to hold a stake in the company’s future. Companies now give their employees stock options that allow employees to share in the company’s success (and profits). The response has been enthusiastic to say the least. At British Aerospace; 89% of those eligible to buy company shares did so. At British Telecom nearly 92% of eligible employees took part. Finally, at Associated British Ports, long synonymous with union disagreements, walkouts, and labor strife, almost 90% of employees now can call themselves owners of the company.

"When people have a personal stake in something," said Henry Dundee of Associated British Ports, "they think about it, they care about, they work to make it prosper." At the National Freight Consortium, itself no stranger to labor problems, the new employee-owners actually voted down an employee pay-increase and, pressured union representatives to relax demands for increased wages and expanded benefits. "Privatization was only the start," says one market analyst, "what we may have here is a new industrial revolution.\

Many companies give their employees stock options to()

A. make them the real owners of the enterprise

B. help them share the success and profit of the enterprise

C. boost the overall productivity of the enterprise

D. avoid union disagreements, walkouts, and labor strife
