题目:

德国经济在席卷全球的金融危机当中受到的冲击与其他发达国家相比较小,主要原因是德国经济建立在先进制造业的基础上,德国的机械装备和汽车制造业保持了很强的竞争力,一些人根据德国的例子得出结论:只有具备强大的制造业竞争水平,一个国家的经济才有变度的稳定性。
如果以下各项为真,哪项能够质疑上述结论( )

A.某国制造业不发达,该国经济一直动荡不安
B.有些制造业不发达的国家在金融危机中受影响较小
C.有些国 * * 持长期经济稳定,却没有发达的制造业
D.有些国家制造业很发达,但经济并没有长期保持稳定

题型:单项选择题

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.

To ease the protest against its projects, Sakhalin Energy()

A. moved its platform from the bay where the whales congregate

B. established a panel to be in charge of its public relationship

C. rejected its program near Sakhalin’s offshore

D. organized some experts to study and protect the whales
