Question

 On the surface, the Hudson River is looking good. The sun on a spring morning shines on the water, off bridges and boats. The blue crabs(蟹)are big,and the striped bass(條紋^) are bigger. On the surface, all these would probably make you think the Hudson was about as healthy as it has been since Indian times.

Sadly，it isn't. A study by the environmental group River-keeper examined an important in?dicator of life of any river,fish,and found discouraging news. Ten of 13 species it examined are reducing, and one―the great and delicious shad(西鯡）一is at a historic low.

  The report blames the usual suspects and a few new ones. The river is getting warmer,and the heat helps starve the water of oxygen. Power plants kill untold millions of fish when they suck up river water to cool their machinery. Invasive species, dirty water and fertilizer runoff and over-fishing in the ocean，where species like shad spend much of their lives，all take their toll.

  Not all fish are struggling. Striped bass are on the increase, as are bluefish and spot-tail shiners. But with other species moving slowly downwards, signs point to a sicker, less stable Hudson ecosystem than many had imagined.

  River-keeper's report shows how little we understand the biology of one of the country's most historic and important estuaries (河口，江口). It is a reminder that even the hardest-fought conservation(對自然環(huán)境的保護)victories may look like the easy ones,and that self-satisfaction can be the death of environmental progress.

B篇通過對魚的分析來闡述哈得遜河的環(huán)保問題。

5. A寫作意圖題文章第一段通過對"the blue crabs"和"the striped bass"的描述，特另l| 是"all these would probably make you think the Hudson was about as healthy as it has been since Indian times."這句話，引起讀者對話題的興趣。

6. B態(tài)度推斷題通過文章最后一句"It is a reminder that even the hardest-fought conserva?tion victories may look like the easy ones，and that self-satisfaction can be the death of environmental progress."可以看出作者對現狀并不滿意，但并不是絕望。

7. B細節(jié)推理題通過"Striped bass are on the increase, as are bluefish and spot-tail shiners."此句，反向推斷即可。

8. D詞義猜測題此處是指把水里的氧氣都耗盡。
