"What excited me most was whether there were planets(行星)in other solar(太阳的)systems where life might exist," he says. "I decided to try to find planets orbiting(沿............. 轨道运行)other stars like our sun.”

And he did. " My fellow researcher Paul Butler and I found our first planet in 1995 ，”Dr. Marcy says. "We worked for ten years without finding anything！But we stuck with it,and our patience paid off.”

Since then,the two scientists have discovered 65 of the more than 100 planets found orbit?ing other stars. Dr. Marcy and Dr. Butler also spotted the first " family" of three planets. In June 2002 they announced another discovery：a Jupiter-like(像木星一样的)planet orbiting star 55 Cancri.

At first, the two researchers found only planets that orbit close to stars. Recently, the sci?entists found planets farther out. The planet orbiting 55 Cancri is a major breakthrough;it is the first sighting of a large gas planet about the same distance from the star as Jupiter is from the sun.

Why is this important? Scientists think that life on the earth may exist because of two spe?cial features(特征)in our solar system. The first is Jupiter.

"Because it's so big,Jupiter pulls comets and asteroids(小行星)，or they all come and hit the earth. " Dr. Marcy explains. " Without Jupiter, life on the earth would likely have been destroyed.”

A second feature is that the earth is a rocky planet where liquid water，which is necessary for life，can exist. Unlike gas planets，rocky planets like the earth have surfaces where water can gather in pools and seas,which may support life. A huge space exists between the Jupiter?like planet and two other planets that lie close to 55 Cancri. Is there an Earth-like planet in the space, too small for us to notice? If so,says Dr. Marcy, "We would have two striking similarities to our solar system：a Jupiter-like planet and an Earth-like planet. And there may be life!"

A new generation addiction is quickly spreading all over the world. Weboholism, a twentieth century disease, affects people from different ages. They surf the net,use email and speak in chat rooms. They spend many hours on the computer, and it becomes a compulsive habit. They cannot stop,and it affects their lives.

Ten years ago，no one thought that using computers could become a compulsive behavior that could affect the social and physical life of computer users. This obsessional behavior has af?fected teenagers and college students. They are likely to log on computers and spend long hours at different websites.

They become hooked on computers and gradually their social and school life is affected by this situation. They spend all free time surfing and don't concentrate on homework, so this ad?diction influences their grades and success at school. Because they can find everything on the websites, they hang out there. Moreover, this addiction to websites influences their social life.

They spend more time in front of computers than with their friends. The relation with their friends changes. The virtual life becomes more important than their real life. They have a new language that they speak in the chat rooms and it causes cultural changes in society.

Because of the change in their behavior，they begin to isolate themselves from the society and live with their virtual friends. They share their emotions and feelings with friends who they have never met in their life. Although they feel confident on the computer, they are not confi?dent with real live friends they have known all their life. It is a problem for the future. This ad?dictive behavior is beginning to affect all the world.

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.
