下表为我国某城镇2000年和2010年的人口统计数据,读表完成下列各题。

小题1:该城镇2000年至2010年人口统计数据的变化显示(  )

A.出生率上升、死亡率下降,导致常住人口总数上升

B.社会养老负担减轻

C.家庭抚养少儿的负担加重

D.15-64岁人口比例上升是受外来人口增加的影响小题2:以下产业有可能促使该城镇常住人口快速增长的是(  )

A.金融服务业

B.汽车制造业

C.电子装配业

D.文化创意产业

答案

小题1:D

小题2:C

题目分析:

小题1:读表格数据,该城镇0-14岁人口比重下降,说明出生率下降,但人口自然增长率仍大于0,所以常住人口总数上升,A错。表中老龄人口比重上升,人口老龄化来得,社会养老负担加重,B错。儿童比重下降,家庭抚养少儿的负担减轻,C错。人口自然增长率下降,15-64岁人口比例上升,是受外来人口增加的影响,D对。

小题2:该城镇常住人口快速增长,可能是劳动密集型产业发展。金融服务业、汽车制造业、文化创意产业都是知识、技术型产业,不是劳动密集型产业,需要劳动力数量少,A、B、D错。电子装配业是劳动密集型产业,需要劳动力多,C对。

Fate has not been kind to the western grey whale. Its numbers have dwindled to 130 or so, leaving it “critically endangered” in the eyes of the International Union for the Conservation of Nature. Fishing-nets, speeding ships, pollution and coastal development threaten the few that remain. Most recently, drilling for oil and gas in their main summer feeding grounds, near Sakhalin island off Russia’s Pacific coast, has brought fresh risks for the luckless creatures. Yet the rush to develop Sakhalin’s offshore fields may yet be the saviour of the species.

When drilling was first discussed in the 1990s, there were muted complaints. When a consortium called Sakhalin. Energy, led by Royal Dutch Shell, announced plans to build an oil platform and lay pipelines in the only bay where the whales were known to congregate, these protests proliferated.

In response, the consortium established an independent panel to advise it on how best to protect the whales and promised to fund its work. It subsequently agreed to change the route of the pipeline at the panel’s suggestion, although it refused to move the platform, as other critics had demanded. It also agreed either to follow the panel’s recommendations in future or to explain publicly why it was rejecting them.

The platforms and pipelines are now complete. Sakhalin Energy exported its first cargo of liquefied natural gas last week. The project, says Shell, is an engineering triumph and a commercial success despite all the controversy.

But has it been a success for the whales Sakhalin Energy says their number seems to be growing by 2.5% a year, although Ian Craig, the firm’s boss, admits that the cause might be greater scrutiny rather than population growth. The scientists on the panel still seem worried. They complain that the firm has not always provided the information they need to assess the threat to the whales. It also has not always followed advice, the scientists’ advice about how noisy construction might scare the animals away, for example, or the speed that boats should travel to minimize the risk of hitting the whales. The scientists warn that the loss of just a few fertile females would be enough to tip the population into irrevocable decline. Last summer, there seemed to be far fewer whales around than normal.

On the other hand, the panel knows this only because Sakhalin Energy funds lots of research on the whales. As a result, it has discovered that they have a wider range than originally thought, which might explain why so few of them showed up off Sakhalin island last year.

Therefore, it is hard to escape the conclusion that, for creatures with a lot as sorry as the western grey whale, a nearby oil project is something of a blessing.

An appropriate title for the passage is most likely to be()

A. More Efforts Needed to Protect the Endangered Whales

B. The Environmental Risks and Rewards of Offshore Oil

C. The Already Endangered Whales Still in Danger

D. More Offshore Oil Projects, More Chances for Whales
