问题 综合

读图,回答下列问题。

(1)此岛最著名的盐场是         盐场,请分析这里有利于晒盐的气候条件。(5分)

(2)该岛西部有我国八大铁矿之一:石碌铁矿,但海南岛的支柱工业中却没有钢铁工业,请分析原因(3分)。

(3)文昌航天发射中心位于中国海南省文昌市附近,前身为中国发射亚轨道火箭的测试基地,后经国务院、中央军委批准在该地建设中国首个滨海发射基地。请分析其区位条件。(5分)

答案

(1)莺歌海 处在季风的背风地带,晴天多;纬度低,气温高,蒸发旺盛。

(2)燃料缺乏,市场狭小,钢铁工业污染重,工业基础薄弱。

(3)有利:纬度低,获得的初速度大;海运便利,可以运输大型的机械设备;地势平坦开阔,面向大海,视野宽阔,有利于观察。不利:为热带季风气候,降水较多。

题目分析:

第(1)题,本题考查盐场形成的区位条件。由图可知,此岛最著名的盐场是莺歌海盐场,由于这里处在季风的背风地带,晴天多;纬度低,气温高,蒸发旺盛,有利于晒盐。

第(2)题,本题考查钢铁工业布局的条件。由于该区域燃料缺乏,市场狭小,钢铁工业污染重,工业基础薄弱,因此虽有丰富的原料,但没有形成钢铁工业。

第(3)题,在海南省文昌市附近建设滨海发射基地的区位条件可从利弊两方面分析。利:纬度低,获得的初速度大;海运便利,可以运输大型的机械设备;地势平坦开阔,面向大海,视野宽阔,有利于观察。弊:为热带季风气候,降水较多。

点评:本题难度较小,以海南岛地形和资源分布为材料考查学生对盐场分布及原因、海南岛的支柱工业中却没有钢铁工业原因、文昌卫星发射基地的区位条件等相关知识的掌握情况。解答本题的关键是明确:(1)对于“有利于晒盐的气候条件”要分析气温降水两大要素。(2)文昌卫星发射中心纬度低,地球自转线速度更大,可以增加发射的有效载荷;濒临南海,有利于大型设备通过海运到达发射基地;火箭残骸落入大海,降低造成危害的概率。

填空题
单项选择题

If you smoke, you’d better hurry. From July 1st pubs all over England will, by law, be no-smoking areas. So will restaurants, offices and even company cars, if more than one per-son uses them. England’s smokers are following a well-trodden path. The other three bits of the United Kingdom have already banned smoking in almost all enclosed public spaces, and there are anti-smoking laws of varying strictness over most of Western Europe. The smoker’ s journey from glamour through toleration to suspicion is finally reaching its end in pariah status.

But behind this public-health success story lies a darker tale. Poorer people are much more likely to smoke than richer ones—a change from the 1950s, when professionals and la-borers were equally keen. Today only 15% of men in the highest professional classes smoke, but 42% of unskilled workers do. Despite punitive taxation—20 cigarettes cost around £ 5.00 ($10.00), three-quarters of which is tax—55% of single mothers on benefits smoke. The figure for homeless men is even higher; for hard-drug users it is practically 100% . The message that smoking kills has been heard, it seems, but not by all.

Having defeated the big killers of the past—want, exposure, poor sanitation—governments all over the developed world are turning their attention to diseases that stem mostly from how individuals choose to live their lives. But the same deafness afflicts the same people when they are ply encouraged to give up other sorts of unhealthy behavior. The lower down they are on practically any pecking order—job prestige, income, education, background-the more likely people are to be fat and unfit, and to drink too much.

That tempts governments to shout ever louder in an attempt to get the public to listen and nowhere do they do so more aggressively than in Britain. One reason is that pecking orders matter more than in most other rich countries: income distribution is very unequal and the unemployed, disaffected, ill-educated rump is comparatively large. Another reason is the frustration of a government addicted to targets, which often aim not only to improve some-thing but to lessen inequality in the process. A third is that the National Health Service is free to patients, and paying for those who have arguably brought their ill-health on themselves grows alarmingly costly.

Britain’ s aggressiveness, however, may be pointless, even counter-productive. There is no reason to believe that those who ignore measured voices will listen to shouting. It irritates the majority who are already behaving responsibly, and it may also undermine all government pronouncements on health by convincing people that they have an ultra-cautious margin of error built in.

Such hectoring may also be missing the root cause of the problem. According to Mr. Marmot, who cites research on groups as diverse as baboons in captivity, British civil servants and Oscar nominees, the higher rates of ill health among those in more modest walks of life can be attributed to what he calls the "status syndrome". People in privileged positions think they are worth the effort of behaving healthily, and find the will-power to do so. The implication is that it is easier to improve a person’s health by weakening the connection between social position and health than by targeting behavior directly. Some public-health experts speak of social cohesion, support for families and better education for all. These are bigger undertakings than a bossy campaign; but more effective, and quieter.

Which of the following is NOT a reason for Britain’s aggressiveness in the public-health campaign()

A. The government is frustrated in curing smoking-related diseases

B. The government is keen on eliminating social unfairness

C. The free health service proves very expensive

D. The gap between the rich and the poor is very big
