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(条紋^) 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(西鲱)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(对自然环境的保护)victories may look like the easy ones,and that self-satisfaction can be the death of environmental progress.

 Deserts are found where there is little rainfall or where rain for a whole year falls in only a few weeks' time. Ten inches of rain may be enough for many plants to survive if the rain is spread throughout the year. If it falls within one or two months and the rest of the year is dry, those plants may die and a desert may form.

Sand begins as tiny pieces of rock get smaller and smaller as wind and weather wear them down. Sand dunes(沙丘)are formed as winds move the sand across the desert. Bit by bit,the dunes grow over the years,always moving with the winds and changing the shape. Most of them are only a few feet tall,but they can grow to be several hundred feet high.

  There is,however, much more to a desert than sand. In the deserts of the southwestern United States, cliffs(悬崖)and deep valleys were formed from thick mud that once lay beneath a sea more than millions of years ago. Over the centuries, the water dried up. Wind,sand,rain,heat and cold all wore away at the remaining rocks. The faces of the desert mountains are al?ways changing―very,very slowly―as these forces of nature continue to work on the rock.

  Most deserts have a surprising variety of life. There are plants, animals and insects that have adapted to life in the desert. During the heat of the day,a visitor may see very few signs of living things, but as the air begins to cool in the evening, the desert comes to life. As the sun begins to rise again in the sky,the desert once again becomes quiet and lonely.

C.     Because most deserts come from seas.

D.     Because rocks are hard to be worn down.

A. in the morning    B. in the afternoon

C. in the evening    D. all day and night

(   ) 4. Which of the following can act as the title of the passage?
