[单项选择] Passage Three
Ten years ago, when environmental
lawyer Kassie Siegel went in search of an animal to save the world, the polar
bear wasn’t at all an obvious choice. Siegel and Brendan Cummings of the Center
for Biological Diversity in Joshua Tree, Calif. , were looking for a species
whose habitat was disappearing due to climate change, which could serve as a
symbol of the dangers of global warming. Her first candidate met the
scientific criteria—it lived in ice caves in Alaska’s Glacier Bay, which were
melting away—but unfortunately it was a spider. You can’t sell a lot of T shirts
with pictures of an animal most people would happily step on.
Next, Siegel turned to the Kittlitz’s murrelet, a small Arctic seabird
whose nesting sites in glaciers were disappearing. In 2001, she petitioned the
Department of the Interior to add it to the Endanger
A. call on people to take actions against global warming
B. make people aware of the danger of environmental damage
C. introduce to people a new concept of environmental protection
D. remind people of the importance of protecting endangered species

Passage Three
Could the bad old days of economic decline be about to return Since OPEC agreed to supply-cuts in March, the price of crude oil has jumped to almost $ 26 a barrel, up from less than $10 last December. This near-tripling of oil prices calls up scary memories of the 1973 oil shock, when prices quadrupled, and 1979 1980, when they also almost tripled. Both previous shocks resulted in double-digit inflation and global economic decline. So where are the headlines warning of gloom and doom this time
The oil price was given another push up this week when Iraq suspended oil exports. Strengthening economic growth, at the same time as winter grips the northern hemisphere, could push the price higher still in the short term.
Yet there are good reasons to expect the economic consequences now to be less severe than in the 1970s. In most countries the cost of crude oil now accounts for a smaller share of the price of petrol than it did in the 1970s.
A. global inflation,
B. reduction in supply.
C. fast growth in economy.
D. Iraq’s suspension of exports.
[单项选择] Passage Three
Within fifteen years Britain and other
nations should be well on with the building of huge industrial complexes for the
recycling of waste. The word rubbish could lose its meaning because everything
that goes into the dumps would be made into something useful. Even the most
dangerous and unpleasant wastes would provide energy if nothing else.
The latest project is to take a city of around half a million inhabitants
and discover exactly what raw materials go into it and what go out. The aim is
to find out how much of these raw materials could be provided if a plant for
recycling waste were built just outside the city. This plant would recycle not
only metal such as steel, lead and copper, but also paper and rubber as
well.
Another new project is being set up to discover the best
ways of sorting and separating the rubbish. W
A. To deal with wastes in a better way.
B. It’s a good way to gain profits.
C. It’s more economical than to dump wastes in some distant places.
D. Energy can be got at a lower price.
